Litlhokomelo tsa Tšireletso

This well submersible pump is designed for clean water. It is strictly prohibited to discharge sediment and mud in the newly drilled well. The voltage standard of the submersible pump is 380/50HZ. Other voltage levels of the submersible motor need to be customized. Underground cables must be waterproof and equipped with start-up equipment, such as distribution box, etc. Start-up equipment should have common motor comprehensive protection functions, such as short circuit overload protection, phase loss protection, undervoltage protection, grounding protection, idling protection, etc., so that the protection device can trip in time in case of abnormal conditions. The pump must be reliably grounded during installation and use. It is prohibited to push and pull the switch when hands and feet are wet. The power supply must be cut off before installation and maintenance of the pump. An obvious "anti-electric shock" sign must be set up where the pump is used. Before going down the well or installation, the inner cavity of the motor must be filled with distilled water or non-corrosive clean cold water, and the water / drain bolts must be tightened. When testing the pump on the ground, water must be injected into the pump chamber to lubricate the rubber bearings. The instantaneous start time shall not exceed one second to check whether the steering is correct, as indicated by the steering indicator. Pay attention to safety and ensure that the pump is erected to prevent overturning and causing injury. Strictly in accordance with the provisions of the pump lift and flow range of use, to prevent the pump with a large flow at low lift, or at high lift with a large pull, resulting in extreme wear of thrust bearings and other parts, the motor overload burnout. After the pump into the well, the need to measure the insulation resistance of the motor and the ground, not less than 100MΩ. After the start, regular observation of voltage and current, check whether the motor winding insulation meets the requirements of the provisions. If the temperature of the storage location is lower than the freezing point, the water in the motor cavity should be drained to prevent the water in the motor cavity from freezing and damaging the motor due to low temperature.

5.A fuse is burned out.
6.The water supply pipe is damaged.
7.The motor's thermal insulation resistance is lower than 0.5 megaohm.
Unit disassembly:
1.Untie the cable tie, remove the pipeline part, and remove the wire plate.
2.screw down the water bolt, put the water in the motor chamber.
3.remove the filter, loose the fixed screw on the coupling to fix the motor shaft.
4.screw down the bolt connecting the water inlet section with the motor, and separate the pump from the motor (pay attention to the unit cushion when separating, to prevent the bending of the pump shaft)
5.the disassembly sequence of the pump is: (see figure 1) water inlet section, impeller, diversion shell, impeller...... check valve body, when removing the impeller, use special tools to loosen the conical sleeve of the fixed impeller first, and avoid bending and bruising the pump shaft in the process of disassembly.
6.the disassembly process of the motor is: (see figure 1) place the motor on the platform, and remove the nuts, base, shaft head locking nut, thrust plate, key, lower guide bearing seat and double head bolt from the bottom of the motor in turn, and then take out the rotor (pay attention not to damage the wire package) and finally remove the connecting section and upper guide bearing seat.
7.unit assembly: before assembly, the rust and dirt of the parts should be cleaned, and the mating surface and fasteners coated with sealant, and then assembled in the opposite order of disassembly (the motor shaft moves up and down after assembly for about one millimeter), after assembly, the coupling should be flexible, and then the filter screen test machine. Submersible pumps shall be taken out of the well for dismantling and maintenance according to Article 5 after a year of operation, or less than a year of operation but two years of diving time, and the worn parts shall be replaced.
