Maintenance

1.1

General

These instructions concern the repairs which can be handled by a local service engineer. Please note that during all mentioned repairs all precautions are to be taken and the pump always has to be disconnected from the electrical supply. The numbers mentioned after the parts refer to the position numbers of these parts in the exploded view drawing of the pump concerned.

Protect the pump if there is a risk of frost. Proceed as follows: 1. Close all pump valves.

2. Drain each pump and/or the system.

3. Remove all plugs from the pump.

4. Open the shut-off and fill/air vent plug, if present.

1.3.2

WARNING Never allow the pump to run dry

1.2

Turn the shaft every three months1. This protects the seals from seizure.

Replace VE non-return valve

After an extended period of nonoperation or storage During first start-up, check the mechanical seals for leakage due to seizure or dehydration of the lubricating film. If so, please proceed as follows: 1. Turn shaft manually; 2. Check if the mechanical seal is still leaking.

If the seal is still leaking: 1. Disassemble the mechanical seal.

2. Thoroughly clean and degrease the sealing surfaces.

3. Assemble the mechanical seal again and retry start-up.

ID0996

Figure 1: replace VE non-return valve

0996/15082003

If this doesn’t solve the seal leakage, replacement of the mechanical seal is necessary.

To replace the non-return valve of the pump types VE, proceed as follows: 1 2 3 4

Use a pair of pliers to remove the non-return valve.

Remove the O-ring.

Install a new O-ring.

Install the new non-return valve.

Figure 2: Motor model

Every impeller creates axial load. The larger the impeller inlet diameter, the more pressure is forcing the pump shaft downwards (axial load). The more impellers the bigger the axial load.

The pump bearing is only meant to centre the shaft and, is not designed to carry any axial load. The axial load is designed to be carried by the bearing in the motor.

General motor specifications • AC squirrel cage induction motor.

• T.E.F.C. Totally enclosed fan cooled.

• Protection IP55 (single phase IP54).

• Insulation class F. • Temperature rise class B. • Noise levels conform IEC 60034-9.

• > 2.2 kW standard 3 x PTC. There are 3 possible mounting configurations.

Specific features

DP motors have specific features for use on multistage vertical pumps. A number of specific features are to be taken into consideration:

The required driven end bearing type for this 4 kW motor is 6306-2Z-C3.This particular bearing has a dynamic bearing load of 28100 N, which is used to calculate the guaranteed running time of the bearing before the wear exceeds the factory tolerances.

• • • •

Long term testing of the worst case pump model with an axial load of 2448 N (V(C/S) 2, 4, 6/... B at 60 Hz) shows its suitability to drive the pump with an expected minimum life time of 20.000 hours.

Reinforced bearing; Axially fixed driven-end bearing; High temperature grease; Smooth shaft without keyway.

ability to function and shorten the lifespan, caused by losing its lubricating properties or because it becomes too fluid which can cause the bearing to lose the grease.

Using a motor with a different bearing on the driven end, consequently leads to a different expected lifetime of the motor.

At long term running, the bearings could lose their grease and shorten the lifetime of the motor bearing.

When the motor bearing is damaged the axial position of the pump shaft is incorrect which could lead to extreme damages of the hydraulic assembly of the pump.

2.6

•

2.4

Fixed axial play

Regarding the above mentioned, it is also important to avoid axial movement of the motor shaft, which directly influences the axial position of the pump shaft and impeller in relation to the diffuser. An incorrect position of the hydraulic assembly could influence the hydraulic performance of the pump (Internal leakage or flow disturbance per stage).

2.5 10

High temperature grease ATTENTION Only applicable for motors of 1.5 kW and up!

When the motor is subjected to the maximum load and the ambient temperature is high (up to maximum 40 °C), the winding can reach its maximum allowable temperature difference of Δt=80 °C (insulation class F/ temperature rise class B). In these situations it is important that the bearing grease does not lose its

Smooth shaft without keyway

The pump shaft (210) is coupled to the motor shaft with a clamp coupling (862). To avoid imbalance and to insure maximum grip between the shafts and the coupling, the motor shaft is not provided with a keyway.

In case of a special / other brand motor which is provided with a keyway, it is recommended to assemble a half key in the keyway prior to clamping the coupling on the shaft.

2.7

Voltage range

To make standard DP motors applicable for most countries and power supply ranges, they have an extended voltage supply range and can be used at 50 Hz and 60 Hz. WARNING The motor/pump combination must be selected for 50 Hz or 60 Hz operation.

Nominal current

The current of the motor depends on the load, used voltage and frequency. On pumps of design version B, motors ≥ 0.75 kW are not subjected to a load higher then the nominal power output. Therefore the current as mentioned on the nameplate of the motor is the value which is to be used to protect the motor/ pump combination. No current will be mentioned on the nameplate of the pump.

2.9

Motor temperature ratings

The electric motor's insulation system separates electrical components from each other, preventing short circuits, winding burnout and failure. To prevent failure of the insulation it is important that it is not subjected to temperatures to which it is not resistant.

A thermal class (insulation class) is used to indicate the maximum temperature at which the insulation is designed to be able to operate for a long and predictable running life of 20,000 hours or more. The table below provides a summary.

When operating at service factor loading, the hot spot temperatures can exceed the insulation rating, resulting in shortened motor life.

The table shows the temperature ratings, temperature rise allowances and hot spot allowances for various enclosures and service factors of standard motors. The table also shows the highest allowable stator winding temperatures for long insulation life.

The standard motors for the V(S) are designed to operate cooler than their thermal class allows. The standard motors have Class F insulation with a Class B temperature rise. This gives an extra thermal margin.

2.9.1

Ambient temperature

Ambient temperature is the temperature of the air surrounding the motor or the room temperature in the vicinity of the motor. This is the temperature that the entire motor would assume when it is shut off and completely cool. The basic ambient temperature rating point of all standard motors is 40 °C.

2.9.2

Figure 3: Insulation classes

Temperature rise

Temperature rise is the change in temperature of the critical electrical parts of the motor when it is being operated at full load. If the motor is located in a room with a temperature of 20 °C, and operates continuously at full load, the winding temperature rises from 20 °C to a higher temperature. The difference between starting temperature and final elevated temperature, is the motor’s temperature rise.

The amount of temperature rise is always additive to the ambient temperature.

11

2.9.3

Hot spot allowance

The average temperature rise of a motor can be determined by measuring the difference between the cold and hot ohmic resistance of the winding. As there will always be regions inside a motor that are hotter then others, an allowance is added to the average temperature to indicate what the maximum temperature is. This is called the 'Hot spot allowance'.

2.9.4

Insulation class

Standard DP motors are designed with insulation class F - B-rise. This means that the motor is capable to withstand temperatures according to class F but at nominal power will only have an increase in temperature according to class B. This difference in thermal capability be used to allow for:

• • • • • •

Higher ambient temperatures (Limited) overload High or low voltages, voltage imbalance, blocked ventilation, high inertia loads, high frequent starts Operation in environments with lower ambient pressure Any other factors that can produce above normal operating temperatures Applying a motor at lower powers extends the motor life expectancy

2.9.5

Insulation life

Insulation life is affected by many factors aside from temperature. Moisture, chemicals, oil, vibration, fungus growth, abrasive particles, and mechanical abrasion created by frequent starts, all work to shorten insulation life. On some applications if the operating environment and motor load conditions can be properly defined, suitable means of winding protection can be provided to obtain reasonable motor life in spite of external disturbing factors.

As the load increases with the frequency it is important that the combination of motor, pump and frequency is chosen correctly to prevent overload of the motor.

Efficiency and power factor

The total power required by an inductive device as a motor or similar consists of: • Active (true or real) power (measured in kW) • Reactive power - the non working power caused by the magnetizing current, required to operate the device (measured in kilovar, kvar) The power factor defined by IEEE and IEC is the ratio between the applied active (true) power - and the reactive power, and can in general be expressed as:

This means that when the power factor is low, the reactive power is high. Because the reactive power is not measured but still has to be supplied by the energy company, motor manufacturers make an effort to make the power factor as high as possible within the possibilities of the construction.

The efficiency of a motor is defined as: η = P shaft / P active . 100 % where η (eta) = efficiency P shaft = power which flows through the shaft (W) P active = electric power through the mains (W) For example:

Pmotor = Pshaft / η

For models with a taper piece, assemble the taper piece.

Assemble the motor (800/801) with the hexagon head bolts (901.02) and washers (554.02).

Insert the pin for coupling (560) in the shaft.

Assemble the coupling shells (862) and loosely fasten them with the hexagon socket head cap screws (914.01) and nuts (920.01).

Use a tool like a suitable tire lever under the coupling to lift the shaft (210) 1.5 mm. Make sure that the coupling shells can move freely over the motor shaft. For motors with an angular ball bearing make sure the motor shaft is not lifted.

While the shaft is lifted, fully tighten the hexagon socket head cap screws (914.01) in a crosswise fashion to the specified torque.

Make sure that the gaps between the couplings are equally divided on both sides. See figure 26 Tighten the coupling DPV(S) 2 - 25 B / 15 C or see figure 27 Tighten the coupling DPV(S) 40 125 B.

WARNING The torques given in the table below are valid for materials at 20 °C, therefore it is essential that pumps are assembled at 20 °C ambient temperature.

Assembling the motor and adjusting the pump shaft DPV 10/15 B For models with a taper piece, assemble the taper piece.

Assemble the motor (800/801).

Insert the pin for coupling (560) in the shaft.

Assemble the coupling shells (862) and loosely fasten them with the hexagon socket head cap screws (914.01) and nuts (920.01).

Use a tool like a suitable tire lever under the coupling to lift the shaft (210) 1.5 mm. Make sure that the coupling shells can move freely over the motor shaft. For motors with an angular ball bearing make sure the motor shaft is not lifted.

While the shaft is lifted, fully tighten the hexagon socket head cap screws (914.01) in a crosswise fashion to the specified torque.

Make sure that the gaps between the couplings are equally divided on both sides. See figure 71 Tighten the coupling DPV(S) 2 - 25 B.
