| Breakdown Case |
Produce Reason |
Obviate Method |
| Have not running-water, intermittent water outlet, have a small amount of .water |
1 、 The engine is not started up.
2 、 The pipe-line is chocked.
3 、 The pipe-line is broken.
4 、 The filter-net is chocked.
5 、 The absorbed-water-pipe is out of water.
6 、 Electric submersible pump reverses.
7 、 The pump's threads or its impellors are damaged.? |
1 、 Repair the electricity-line, and the motor troubles or pump jam occurs.
2 、 Get rid of the chock.
3 、 Re-repair the pipe-line's leak.
4 、 Clear the dirty.
5 、 Add a sending-pipe or change the new-pump with the high-lift.
6 、 Change the motor's running-direction.
7 、 Change the new mouth-circular and impellor |
| The electric current increases or the current pointer swings regularly. |
1 、 The current of pump is large the lift is low and exceed the operation-procedure, and its overload.
2 、 The guide bearing of motor, the rubber-bearing or the bearing-cover and the mouth-circular on the pump is damaged.
3 、 The bearing is damaged and the cover board of impellor is wore and tear.
4 、 The bearing is bent.
5 、 The variable water-level drops, so as to be the intermittent water outlet.
6 、 The rotor of motor is bread off. |
1 、 Check the diving-depth and see if it reaches the standard-lift. If necessary, use the valve and control its flow.
2 、 Change the new bearing or use the new mouth-circular.
3 、 Change the bearing and adjust its distance into the best-condition.
4 、 It should be repaired in the factory and then change the new-axle.
5 、 Change the other new pump.
6 、 Change the new rotor. |
| The insulation resistance in thermal state lower than 0.38 megohms. |
1 、 The electromagnetic-wire with water-proof is reduced.
2 、 The rubber electric-wire is damaged.
3 、 The electric-wire's joint lost the function or the insulation. |
1 、 Open the winding-can, find out the faults and then pack it well by the self-adhesive rubber tape.
2 、 Find out the leakage, and then pack it well by the self-adhesive rubber-tape.
3 、 Open the cable-joint, connect them and pack it again. |
| The motor can not start up to run or to be some noises. |
1、 The lead is not connected firmly or the running-parts are not firm.
2 、 The bearings strike together and lead to the stop.
3 、 There are some unusual things which touch the pump, so as to be the jam.
4. The voltage is lower.
5 、 The hot equipment leaps.
|
• Repair the broken-wires and then connect with the fuse.
2 、 Repair or change the new bearing, or axle.
3. Clear the unusual things.
4 、 Adjust the power-pressure.
5 、 After the replacement became cooling or replacement by hand. |
| The pump-sets cause the noise or strong-vibration. |
1 、 The main-body of the motor is not balanced.
2 、 The impeller is not balanced.
3 、 The axle bents.
4 、 The bearing and its cover is damaged.
5 、 The flanges or its bolts are not tight. |
1 、 Make the impeller-pieces to be balance.
2 、 Make the impeller to be balance.
3 、 Repair or change the new axle.
4 、 Change the bearing.
5 、 Fasten the loose bolt. |
| The motor's winding-can is damaged completely |
1、Water is not enough in the inner of motor.
2、The single-way is running.
3、It cant not be stopped for a long time. |
1. The inner chamber of motor must be full of the clear-water.
2、Check the power-equipment and starting.
3、Reduce flow , reduce its load and adjust its main-equipment, so as to control the electric-current and voltage. |
