WHAT A DIFFERENCE 50 years makes. For those of you who have been in the business as long as I have, you can probably remember when 2500 PSI was considered high pressure, seals were made of leather, and check valves were the size of your two fists.

I’m a second-generation owner of Baltimore Hydraulics Inc. and currently in the process of passing it to my son Chris. Significant and positive changes have taken place in my time, and I’m confident that they will continue under Chris’s guidance.

I’ve seen us go from a company that repaired automotive jacks and air tools to one that builds components and systems, powering some of the country’s most critical operations. In the beginning, all we needed was 1,200 square feet, some basic shop equipment and an assortment of hand tools. Today we are outgrowing a 40,000 square foot building filled with specialized tools, machinery and test equipment.

We’ve gone from manually operated lathes and mills to CNC machines that produce quality parts in half the time, allowing faster service to our customers.

I’m sure we all have stories of how the world has changed in our lifetime, but I can promise you that some basic truths have never changed. These are values that every customer has sought after in my 50 years, and I’m sure are the keys to success in the future.

Quality – Quality comes first. Every decision we make must be weighed against its ability to improve the quality of the products and services we offer.

Integrity – We must do what we say and use our knowledge and experience for the benefit of those who need our products and services.

Relationships – We work on equipment, but we work for and with people. We must be trustworthy and respectful to all individuals with whom we work while earning their trust and respect in return.

Teamwork – We must constantly be building a team of individuals who wish to use their skills and talents for the benefit of the whole. We are to provide the tools and training required to allow each individual the opportunity to increase their contribution and advance their personal well-being.

My father was a man of faith and it came natural for him to operate with these values guiding him through life. Today, Baltimore Hydraulics has adopted these as the core values of our business. They guide every decision we make and consistently reveal the right thing to do in all situations. If you put yourself in your consumers’ shoes, you’ll see that this is precisely what you would want with every purchase you make. 

New Problem:

Building a Windmill

By Ernie Parker, CFPAI, CFPSD, CFPS, CFPMM, CFPMT, CFPMIP, CFPMMH, CFPMIH

»

IF ONE WERE to build a 10’ diameter windmill connected to an air compressor with a direct drive and a steady wind of 15 MPH, how many CFM would you expect to get from an air compressor at 100 PSI with 25% overall efficiency? How many SCFM?

olution to the Previous Problem: Decreasing Downstream Pressure to Increase Flow

Air velocity cannot exceed the speed of sound (sonic velocity) which occurs when the pressure drop across an orifice drops 47% of the absolute inlet pressure (when the downstream pressure is reduced to 53% of the absolute inlet pressure). A mistake that is often made is to neglect to calculate using absolute pressure.

To determine the minimum downstream gauge pressure that would that would no longer increase flow, multiply the absolute inlet pressure by 53% and then subtract one atmosphere. The absolute pressure is 0.690 MPa + 0.101 MPa = 0.791 MPa x 0.53 = 0.419 MPa. Subtracting atmosphere of 0.101 MPa = 0.318 MPa. 114.7 psia x 0.53 = 60.791. Subtracting one atmosphere of 14.7 psia = 46.091 psig or 46 PSI, not 47 PSI. Dropping the pressure below 46 PSI will not increase the flow.

Calculating for pressure drop: The absolute pressure is 0.690 MPa + 0.101 MPa = 0.791 MPa Pressure of 0.791 MPa x 0.47 = 0.372 ΔMPa or (100 psi + 14.7 psi = 114.7 psia). 114.7 psia x 0.47 = 53.909 Δpsi.

A Change Will Do You Good: Nine Steps to Lead Your Team Through Uncertain Times

By Kate Zabriskie, President, Business Training Works, Inc.

»

IF THERE IS one thing about business that doesn’t change, it’s that business will always change! Be it through the advent of new technology, loss of a key employee, new laws that govern the way your industry does business, or even a takeover by another company. No matter what the change may be, the last thing your team wants to hear from you is…

“Ok, now what do we do?”

An effective leader will need to lead their team through any change that should occur and do so with confidence to inspire others to be confident as well. The transition should be as smooth as possible and be done so in a way that looks as if the change were already expected.

Employees and contractors may feel unsure and fearful about any new direction a business may be taking or change they are forced to deal with; so as their leader, their cues as to how to act and how to feel will come directly from you. As such, it is important that you have a solid action plan in place to deal with just such a scenario.

Below are nine tips to help you when leading your team through uncertain times:

1

THE PATH TO THE EVENTUAL GOAL IS NOT ALWAYS LINEAR. As a team is dealing with change in the workplace, it is not as simple as announcing it, adapting to it, and moving toward goals.

Employees and even leaders may have changing feelings about the process and that is normal.

Recognizing and addressing these concerns as they arise is a healthy way to deal with them and is expected in a situation that may feel full ofturmoil or even traumatic at times.

CONTINUALLY DEFINE THE CHANGE AS NECESSARY. During a time of uncertainly, rumors abound.

When your team doesn’t know some aspect concerning the change at hand, they will begin to speculate. This can lead to confusion, worry, and employees looking elsewhere for employment.

The best plan of action is to be upfront and communicate with your team any information you have as you get it. Simply knowing what is going on will instill confidence and quell fears, even if the information is not all that good to begin with.

6

DON’T DISCOUNT THE PAST. Oftentimes, new changes mean discarding the old ways of doing things, and projects once seen as vital are “kicked to the curb,” so to speak. This can leave those team members who worked on such projects feeling slighted and that their contributions were worthless. An effective team leader will highlight such projects and give credence to past accomplishments as jobs well done, while at the same time leading the team into the new direction.

2

IDENTIFY KEY LEADERS AND STAKEHOLDERS EARLY. As the process of change begins it is important to identify those in your team who represent true leadership qualities. They can be seen as stakeholders in the process and support you in your efforts to lead the team through the change and onto greater success. These individuals will be crucial in helping to instill confidence and keep the team moving together toward the stated goals.

3

CONSTRUCT A SOLID PLAN. Even small changes need a plan. That plan should address changes in processes, products, and expectations of the people involved. If a change is drastic, you might have to construct an entirely new business plan. Creating a plan and sharing it with your team will go a long way toward giving them a feeling of stability as they move together in this new business environment.

4

IDENTIFY GOALS CLEARLY. Failing to communicate clearly defined goals is one of the worst errors people can make when leading change. If employees don’t have a firm sense of what they are moving toward, they may end up just … moving. Clearly define objectives and how you will support your team in meeting them. Your key stakeholders as identified above will play a vital role here as they lead by example in making decisions and actions that support accomplishing these goals.

7

DON’T HIDE THE CHALLENGES. There will be times when even an effectively created plan will hit a stumbling block or even come to a screeching halt. Don’t hide challenges when they occur; instead, share them with your team. They may have valuable input and will feel more invested in helping to overcome any obstacles as you bring them into the discussion.

8

CAREFULLY LISTEN TO CONCERNS. One issue that many leaders fail at is truly listening to their team. They may take a “this is the way it is now, so deal with it” approach, and this can do much to lower morale and make team members feel defeated in an already scary situation. Instead, make yourself available to your team and listen to them. Sometimes, simply venting about the changing environment will do wonders to help someone deal with what is going on. And other times, their insight could be invaluable in helping you do your job as well.

9

CLEARLY STATE NEW OR ADJUSTED PERFORMANCE OBJECTIVES. Of all the things that will affect the changing workplace environment, uncertainty among team members can be the greatest obstacle to overcome. One way to combat that early on is to clearly state any changes in performance objectives and reviews. Employees will want to know exactly how and when they will be reviewed and what criteria will be a factor. This will allow them to focus on their own objectives and give them a sense of confidence as they move through the changing environment.

Change can be scary, full of surprises, and extremely challenging at times. But if you have a plan of action, communicate effectively with your team, and move toward new objectives with confidence and a team that is committed, you can survive and even thrive in the new adjusted business environment. 

THE EFFECTS OF

PRESSURE COMPENSATED COMPONENTS ON CONTROL SYSTEMS

PRESSURE COMPENSATION (HYDROSTAT FUNCTION) WITH PROPORTIONAL DIRECTIONAL VALVES To maintain a relatively constant flow to an actuator regardless of variations in inlet or load pressures, a pressure compensated flow control can be used to achieve and maintain a somewhat regulated speed. This type of control typically consists of a normally open pressure control (essentially a pressure reducing valve) in series with a fixed or manually variable orifice (flow control).

In this application, the normally open pressure control is commonly known as a hydrostat and can be located either upstream or downstream of the flow control. A 100-150 psi bias spring (typically) holds the hydrostat in the normally open position. See the figure below. With the hydrostat sensing the pressure both upstream and downstream of the flow control and therefore both supply and load pressure, a constant pressure differential equal to the value of the bias spring can be maintained, regardless of changes in the sensed pressures.

By maintaining a constant pressure differential, a regulated flow relative to the setting of the flow control valve can be obtained. Assuming that a proportional directional valve is essentially an electrically adjusted flow control, it can be seen that a hydrostat can regulate flow is a similar manner.

In the example shown, a hydrostat is connected to the P port of a 4 port, three position proportional directional valve. The valve A and B work ports are connected to the inlet ports of a shuttle valve and the shuttle output is connected back to the hydrostat. In operation, when the proportional valve is shifted, pressure at the outlet of the hydrostat (port 1) is picked up by the pilot line and is ported back to hold the hydrostat in the open position. At the same time, load induced pressure developing at the active work port (in this example, port A) is sensed through the shuttle valve and is ported back to the hydrostat (port 3). This load induced pressure along with the bias spring acts to hold the hydrostat in the open position. The outlet pressure acting to close the hydrostat and the load induced pressure trying to keep it open cancel each other out. It is the bias spring then that keeps the hydrostat in the open position and is, therefore, what determines the differential pressure across the proportional valve inlet to the active work port. It is this differential pressure that limits the flow rate across the proportional valve for a given displacement of the valve spool. This technique is called restrictive, meter in pressure compensation. Other types of pressure compensation include 3 port bypass using a normally closed pressure control and post pressure compensation which is used primarily in mobile valves and is not part of the scope of this article.

Although hydrostats used for pressure compensation to regulate flow can provide for a relatively constant actuator speed, their application does not come without an impact on performance, potential cost and physical size. Since a hydrostat only allows for a pressure differential equal to the bias spring to be realized across the proportional valve, flow for a particular proportional valve size will be limited versus being non-compensated. This means that a larger valve than otherwise required may be necessary to pass the specified flow. Larger valves have bigger spools with more mass and require more solenoid force to shift against heavier centering springs. They require more time to move and are not as quick to respond to an input signal as a smaller valve flowing at a higher pressure differential. Should the flow rates be high enough to dictate the need for a pilot operated, two stage valve, the pilot valve itself will contribute to the overall response time of the proportional valve. Smaller valves respond faster and are more sensitive to changes in input signals thereby controlling output flow.

to maintain control of the load. This tends to cause cavitation in the piston end of the cylinder and may require a different type of proportional valve spool or additional circuitry to prevent potential stability issues. See the text “Know How to Size the Proportional Valve” earlier in this section.

When properly applied, pressure compensating hydrostats can be a practical means regulating flow but are most effective in open loop (non-feedback) systems. 

Proportional Directional Valve with Hydrostat and Shuttle Valve

When rapid response and high accuracy are of concern (as typically is the case in industrial systems), one must exercise caution in using pressure compensation for flow regulation in systems that utilize closed loop feedback control. This is particularly the case in the fast acceleration of high mass loads to a target position or velocity. It is also true if the mechanical system has an inherently low natural frequency where the hydrostat is yet another spring-mass system that can introduce disturbances as the feedback loop modulates the proportional valve to target the system set point.

Another area of concern is with tractive (overrunning) cylinder loads that are controlled with a proportional valve having a symmetrical (equal flow area) spool. If the cylinder has a large diameter rod relative to the piston diameter, the resulting high differential area requires the proportional valve to be significantly restricted WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

EATON CONTAMINATION CONTROL SYSTEM DOES THE

rk

DIRTY WORK D

irty hydraulic fluid causes up to 80% of all hydraulic system problems. If hydraulic oil is contaminated, there are a number of detrimental effects that diminish performance or damage system components.

Ramifications include surface corrosion and accelerated fatigue of metal components. Another effect is distinct changes in the physical characteristics of the oil itself, resulting in a different viscosity or compressibility, which can adversely affect the ability of the oil to transfer power.

Recently, Vac-Con, a manufacturer of industrial vacuum trucks and loaders, noticed a clear spike in warranty costs. The company undertook a comprehensive analysis of its entire operation, including issues related to hydraulic oil contamination.

The company enlisted the help of an Eaton distributor to assist with the evaluation, which included an in-depth look at assembly procedures and the quality of the hydraulic oil used in its new trucks. The goal was to minimize any water or other contaminants from entering its trucks’ hydraulic systems.

The company discovered some areas for improvement. It made changes in the assembly areas and changed procedures to ensure that hydraulic oil met cleanliness standards and was free of contamination.

Once a revamped process was in place, the company began looking for a method to reliably test the oil to measure the success of its new procedures. It also wanted to keep records of the readings for warranty purposes.

Knowing particle size distribution of any contamination, water saturation and temperature enables the company to evaluate the precise condition of the system and to determine whether procedural changes were working. This information helps the company take action and cost-saving measures before failures occur.

Eaton’s CCS 4 contamination control system helped provide a real-time snapshot of hydraulic fluid’s condition in the field. The system provides access to simultaneous instant readings of particulate contamination and fluid aging with a single measurement using calibrated in-line sensors.

Monitoring hydraulic fluids in real-time makes it possible to immediately diagnose component and seal wear, and it provides a measurable basis for filter and fluid change intervals. The procedure tests the condition of new fluids as they are introduced into a system to verify the effectiveness of offline filtration systems, and the correct storage and transport of the fluids.

The difference between knowing the condition of new fluids and waiting for a time-consuming laboratory analysis could be the difference between an efficient, reliable system and an early failure.

The testing system eliminates the wait of four or five days for results from a lab. The mobile unit hooks directly to the truck to test the oil in a closed atmosphere.

While the portable testing system duplicates much of the analytical capability offered by traditional lab-based services, it does not eliminate 20

the need for periodic laboratory tests. It simply changes their frequency and the nature of the tests performed. For example, when particle counts begin to increase, operators should still send samples to a lab to identify contaminants and resolve these issues early on.

Industrial vacuum trucks are a significant investment for Vac-Con, so managing hydraulic oil contamination is vital. The company was so impressed with initial testing of the contamination control system that it constructed a new building to use the equipment and test every vehicle’s hydraulic fluid prior to delivery to its customers. The company stopped testing trucks for hydraulic oil contamination with its previous procedures.

Since the introduction of the CCS 4 contamination control system, the company has not had to replace a single valve or pump in its assemblies.

It has not had a single failure in the field and its warranty costs have dropped significantly.  WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

Shipments – Cumulative year‐to‐ date % change (2019 vs. 2018)

This graph of raw index data is generated by the total dollar volume reported to NFPA by CSS participants and compared to the average monthly dollar volume in 2018. For example, the December 2019 total dollar volume for pneumatic shipments are 81.5% of the average monthly dollar volume in 2018. (Base Year 2018 = 100)

The table above is expressed in terms of cumulative percent changes. These changes refer to the percent difference between the relevant cumulative total for 2019 and the total for the same months in 2018. For example, November 2019 pneumatic shipments figure of ‐3.9 means that for the calendar year through November 2019, pneumatic shipments decreased 3.9% compared to the same time‐period in 2018. (Base Year 2018 = 100)

Pneumatic, Mobile and Industrial Hydraulic Orders Index Each point on this graph represents the most recent 12 months of orders compared to the previous 12 months of orders. Each point can be read as a percentage.

For example, 89.8 (the November 2019 level of the industrial hydraulic series) indicates that industrial hydraulic orders received from December 2018 to November 2019 were 89.8% of the orders received from December 2017 to November 2018. (Base Year 2018 = 100)

Total ‐ Hydraulic and Pneumatic Shipments This graph of 12‐month moving averages shows that in December 2019, both hydraulic shipments and pneumatic shipments decreased. (Base Year 2018 = 100)

Husco Hires Graduates from NFPA Fast Track/FAMTEN Hub School

By Lynn Beyer

»

NFPA’S WORKFORCE DEVELOPMENT programs are designed to introduce students to fluid power and connect them to fluid power careers at member companies. Husco is the most recent company to take advantage of this growing talent pool after hiring two full-time employees from Waukesha County Technical College’s (WCTC) Automation Systems Technology program and one intern from the school’s Dual Enrollment program.

Nathan Lodl started as an intern and was quickly brought on full-time while he finished his last semester at WCTC. He is currently working first shift as an automation technician in Husco’s automotive division. Edward McKibbon also started as an intern and was taken on full-time shortly after starting with Husco. He is also working as an automation technician in their automotive division but on a split shift. Spencer Lee was hired as a part-time intern and is working in the same role as Nathan and Edward but as an intern.

New Composite Tubing for Pneumatic and Hydraulic Cylinders

» Mechanical Joining Tools Create Secure, Leak-Proof Joints

»

MECHANICAL JOINING TOOLS join tubing to flanges and fittings, creating secure, leak-proof joints that withstand up to 20,000 pounds of hydrostatic pressure. Superior to welded, brazed or crimped joints, mechanically joined parts will not leak, pull apart, or loosen due to pressure, vibration, or temperature changes. This method allows joints to be rolled to a torque or diameter spec. Rolling to a torque ensures consistent results, regardless of tolerance and variations of the tube OD, wall thickness and component ID. Rolling to a consistent diameter guarantees a consistent ID of the tube, which makes it possible to “iron out” and round up the ID of the tube.

Virtually any annealed or ductile product can be mechanically joined, including mild steel, stainless steel, aluminum, titanium, copped, cupronickel, Inconel and more. A mechanical joining tool (MJT) is ideal for applications in which joints loosen due to vibration, and temperature and altitude changes, and where high pressure is present, including those common in the automotive, fluid power, and the aerospace industries.

HOW IT WORKS A tube is inserted into the flange, then the MJT is inserted into the tube. A generous chamfer or radius should be provided on the backside of the flange.

The opposing end should include a shoulder that the tube can bottom out against to ensure proper position. Flange grooves with sharp corners at the top edge and the bottom of the groove are required. Width of the groove can be 0.062” to 0.375” (1.6 to 9.5mm), with depths from 0.005” to 0.0320” (0.13 to 0.81 mm). Both dimensions are dependent on flange width, thickness and hardness of tube.

When the tube has been rolled to about 25% of MJT expansion required, it makes metal-tometal contact with the flange. At about 50% MJT expansion, the tube metal begins to flow into the grooved serrations of the flange.

When the MJT is completely expanded, grooved serrations are filled to the predetermined groove-fill percentage of the tool. (Groove fill percentages vary by industry and application.)

Once the correct joint has been completed, the rotation of the tool is reversed so that it can be extracted from the assembly, and the cycle can be repeated with new components.

The MJT is ideal for a variety of applications, including hydraulic fittings, fitting and block assemblies for hydraulic components, hydraulic lines, tube installation into transmissions, differentials on large equipment and all types of fluid lines in aircraft.

A NEW COMPOSITE tubing for pneumatic and hydraulic cylinders replaces metallic material in a variety of cylinder applications.

Polygon’s new PolySlide is made of continuous filament-wound glass fiber and polymer resins. The fiberglass filament and resin materials combine to form a high-strength component that exhibits dimensional stability, is non-corroding, impingement resistant and is non-conductive. PolySlide promises strong performance in harsh environments, high and low temperatures, grease, grit, salt, chemicals and other extreme conditions.

PolySlide cylinder tubing sizes range from as low as 0.25-inch inner diameter up to industrial-sized 24-inch inner diameters. The tubing allows the seal to slide over the bore surface contour, minimizing interlocking friction. The inside diameter of the tubing has a smooth finish. Contact with the non-metallic rod guide bearing prevents galling and provides for a low coefficient of friction. A wear-resistant material incorporated into the bore surface further increases the lifespan of the composite cylinder tubing.

The tubing is supplied as a cylinder tube ready for customer assembly or as fully engineered cylinder assemblies for equipment manufacturer applications.

Commonly found in pneumatic and low-pressure hydraulic applications such as fifth wheel actuation, gate valve actuators, water treatment flow control mechanisms and tie rod cylinders, among others, a translucent version of the composite cylinder tubing is also available.
