Greater efficiency with the right torque

Choosing the most suitable torque sensors from ZHYQ’s range can help to maximise efficiency and accuracy.

Torque is a measure of the force that causes an object to rotate while rotational torque is the force exerted on an object to make it rotate spontaneously. The torque sensor is a kind of precision measuring instrument for measuring torque, rotational speed and mechanical power.

Torque sensors use strain gauges that are fitted to the axis of rotation. With this method, a device is required to supply the strain gauge bridge, as well as a device to receive signals from the axis of rotation. This can be achieved by using slip rings or rotary transformers. Nowadays, adjustment electronics and A/D converters are added to the rotating shaft for easier and faster data transfer.

Torque sensors can be used to measure torque in rotating systems and are widely used as automation control tools in various industries.

Static and dynamic are two main types of torque sensors and they’re defined by the way torque or force is measured. A static torque sensor has simpler working principles and measuring methods than a dynamic torque sensor.

Both static and dynamic sensors have a mechanical stop function to improve overload capacity and provide protections in installation and operation process.

There are other common torque sensors such as reaction torque sensor, rotary torque sensor, proximity torque sensor and magnet-to-restrictive transducer. Choosing the most suitable torque sensors can help to maximise efficiency and accuracy.

ZHYQ’s torque measuring instruments are widely used as process control tools to help manufacturers to maximise productivity. They’re mainly used for: •motor, engine, internal combustion engine and other rotating power equipment output torque and power detection •fan, water pump, gear box, and power detection •detection of torque and power in railway locomotive, automobile, tractor, aircraft, ship and mining machinery •detecting torque and power in sewage treatment system •laboratory or other testing, production monitoring and quality control purpose

Controlling lubricants for better bearing

Separation of the rolling elements of a ball or roller bearing depends on a continuous presence of an extremely thin – micron-sized – elastohydrodynamic film of lubricant between rolling elements and raceways.

Under high magnification, even the smoothest surface will appear rough but the lubricant nevertheless must be able to maintain separation if the bearing is to work to its full service life.

The coefficient of friction in a rolling element bearing in hydrodynamic lubrication conditions is in the range of: μ ≈ 0.001 – 0.01 If this is not maintained, then mixed friction results.

If there is insufficient lubricant, or if the lubricant has lost its lubricating properties, an oil film with sufficient load-carrying capacity cannot form. The result will be partial lubrication with metal-to-metal contact – mixed friction — between the rolling elements and raceways, and it will lead to adhesive wear. Mixed friction is μ ≈0.01 – 0.2

In the worst case, where the separating film breaks down completely, there will be boundary friction in the range of μ ≈ 0.1 – 0.25

It’s critical to maintain a separating oil film for friction and to reduce wear. As can be seen from figures above, in approximate terms the hydrodynamic friction coefficient in a rolling element bearing is 10x-20x less than the mixed friction coefficient and 25x-100x less than the boundary friction coefficient.

The presence of separating oil film depends on selecting the correct lubricant with the right properties for a purpose — plus its correct application. This means the lubricant will be replenished at the right rate to maintain the film separating bearing elements.

Discoloured (blue/brown) raceways and rolling elements are a sign of failed lubrication, and mean wear rates will increase. Higher wear rates will in turn create excessive heat — leading to catastrophic failure.

Adhesive wear is a result of lubrication failure under mixed-friction or boundary-friction conditions. Microscopic projections on the sliding interfaces between components will weld together on contact and then be torn apart by the sliding forces. This will create minute cavities on one surface and a build-up on the other.

This damage has a compounding effect because, once it starts, the lubrication problems increase due to surface damage problems followed by a higher increase rate of surface damage. Adhesive wear includes scoring, galling, seizing and scuffing.

Skid smearing occurs when rolling elements slide, rather than rotate, as they pass from the unloaded zone to the loaded zone, especially in large bearings — and this will be exacerbated by old or too-stiff grease.

When smearing occurs on roller surfaces and in the raceways of spherical roller bearings and roller rotation is retarded in the unloaded zone, the lower rotational speed then results in sliding and more smearing as the rolling elements then accelerate in the loaded zone.

Correct lubrication depends on: •The right amount of lubricant – less is more. Rolling element bearings in most applications operate at their optimum temperature when the minimum amount of lubricant is used. The quantity of lubricant required also depends on the other functions it must perform, such as in slow moving and/or heavily loaded bearings, corrosion protection, sealing and purging. However if this is a requirement then ideally provision should be made to lubricate the seals separately to the bearings. •The right lubricant – consideration needs to be given to bearing type, speed, load, vibration, temperature and conditions. •Clean lubricant

Ultrasonic flowmeter a lightweight, quality choice

The KATflow 200 is a lightweight flowmeter that’s incredibly easy to use and can be operated onehanded, which makes it an ideal tool for use in confined spaces or when working at height.

Used for non-invasive and non-intrusive flow measurement of liquid and liquefied gases, the KATflow 200 offers performance normally associated with more complex and expensive devices.

The KATflow non-invasive flowmeters work on the transit time ultrasonic principle. This involves sending and receiving ultrasonic pulses from a pair of quality and robust sensors and examining the time difference in the signal.

Katronic uses clamp-on ultrasonic transducers (sensors) that are mounted externally on the surface of the pipe and which generate pulses that pass through the pipe wall.

The flowing liquid within causes time differences in the ultrasonic signals, which are then evaluated by the flowmeter to produce an accurate flow measurement.

The advanced electronics of the flowmeter compensate for and adapt to changes in the flow profile and medium temperature to deliver reliable measurements.

The flowmeter is equipped with one measurement channel to monitor the flow in one single pipe at a time.

The instrument is supplied with an internal data logger and software for the recording and download of measured values.

Additionally, the KATflow 200 can be equipped with an integrated wall thickness gauge to provide further information about the application parameters.

Thanks to its intuitive instrument menu, Setup Wizard, and Audible Sensor Positioning Assistant™ the flowmeter can be set up and its sensors correctly installed in a matter of minutes.

Flexible, complementary accessories

The key requirements for MFB Products’ accessories range are power, air and cable management, and shelving. Accessories complement MFB’s enclosure cabinets and the range offers flexible options.

Stable and reliable power distribution access is key to all server enclosure installations. The MFB range of horizontal and vertical power distribution units (PDUs), can be defined in two categories – passive and active. MFB’s standard passive range of PDUs are available in 10-amp, 15-amp, 20amp- and 32-amp wiring configs with Australian outlets, IEC C13 or IEC C19 Outlets. MFB’s range of plugs include Aust, IEC or Captive (screw lock) fitted to a 2.5 meter lead by default. MFB’s Australian-designed and manufactured IP Networked (active) range of PDUs are available in a vertical or horizontal format in 230V single phase or three phase. Outlets same as per passive with optional locked IEC outlets.

The Sentinel range has a variety of options to view power, temperature and humidity levels via a web browser or receive SNMP-based alarms when conditions exceed defined thresholds. Information on total amp draw, humidity and temperature are also displayed directly on the PDU via touch screen.

Both the standard range of PDUs and MFB’s custom range are manufactured in Australia in compliance with AS/NZS 3000:2018

Heat build-up in server cabinets demands consideration. MFB offers as standard roof-mounted fan trays, door fan units (Class B&C) and 19” rack mounted fan trays. Using 120mm x 120mm 230V AC fans with an airflow of 87 CFM per fan, MFB fan trays provide an effective airflow solution which draws the heat out of cabinets and directs it to the atmosphere.

Optional accessories include thermostats to regulate the fan cycle according to ambient temperature, and/or optional speed controller to manage the speed of fans reducing airflow and noise.

Cable management is a key attribute in effective server cabinet installation. With increased equipment use, unmanaged cabling becomes a problem when fault-finding and maintaining airflow. Good cable management not only saves time but reduces on-site labour costs.

MFB offers a large range of cable management systems, from 19” rack mount wire management trays, cable retaining hoop panels, to round, square and rectangle lacing rings to sophisticated, ful-llength vertical cable ducts typically designed for excessive cabling. Finally, MFB’s vertical cable trays act as a wire management system, using toolless mounting (No cage nuts or screws required) `To further complement MFB’s enclosure range, shelving is available in both a static (fixed) format, or a telescopic format for regular, easier access. MFB’s standard fixed shelves are load-rated to 50kgs or for more grunt, out heavy-duty shelves are load rated to 200kgs – with equipment evenly distributed. For telescopic shelves and drawers, MFB uses the Accuride slide systems for their smooth action under heavy loads, for Accuride’s superior features and extreme durability. MFB also offers front mounting, cantilever shelves for smaller, lightweight equipment.

Servo cylinder boosts mineral recovery

SMC’s IN-777 air servo cylinder

One of the world’s largest gold mining companies operating in Australia sought a means to improve air cylinder operation for the dart valves in their flotation cells. They installed new air servo cylinder technology from SMC Corporation Australia|New Zealand and achieved numerous benefits including product recovery.

The SMC air servo cylinder series IN-777 has enabled the reduction and removal of pinch points thus improving safety. It has also saved time during calibration and improved positioning, delivering increased froth velocity for enhanced gold and copper recovery. “The optimised speed of the IN-777 means that it responds quickly to changes in process conditions, maintaining a constant froth velocity,” explains Vince Marcucci, Global Accounts Manager, Resources Sector for SMC Corporation ANZ.

IN-777 in action

The IN-777 air servo cylinder is designed for rugged mining applications in mineral processing, and bears IP67 rating (full protection against dust and water). It is predominately used in concentrators, specifically for flotation cells, designed to recover valuable commodities such as nickel, zinc, lead, gold, copper, silver, molybdenum and phosphate.

“The recovery process is achieved through froth,” explains Vince. “A bond forms between the minerals and the bubbles created during the aeration, agitation, and introduction of specific chemicals to the pulp. The minerals adhere to the bubbles (froth) which float to the top of the cell and cascades over into the ‘Concentrate Launder’.”

The IN-777 features HART Communication protocol, allowing for integration with mining communication systems, for enhanced control, feedback and diagnostics. “In addition, this cylinder delivers high positioning repeatability of 0.5 mm, providing accurate level control for maximum froth velocity, and adjustable speed control levels”. With one-touch stroke calibration, LED diagnostics and failsafe ports, the IN-777 is favoured for its low-maintenance operation.

“SMC is pleased with the outcome of these installations and is proud to partner with the mining industry to increase their extraction rates and improve efficiencies” concludes Marcucci.
