 This well submersible pump is a pump suitable for clean water. It is strictly prohibited to dig new wells and pump dirty water containing sediment. The voltage grade of the pump is 380/50HZ, and other submersible motors with different voltage grades need to be customized. Underground cables must be waterproof cables and must be equipped with starting equipment, such as distribution boxes, etc. The starting equipment should have common comprehensive motor protection functions, such as short circuit overload protection, dephase protection, undervoltage protection, grounding protection and idling protection, etc., in order to prevent timely tripping when abnormal conditions occur. During the installation and use process, the pump must have reliable grounding. It is strictly prohibited to push and pull the switch when your hands and feet are wet. The power supply must be cut off before installation and maintenance of the pump. An obvious sign "anti-electric shock" must be set up where the pump is used. Before going down the well or installation, the motor must be filled with distilled water or non-corrosive clean cold water, and the water inlet and outlet bolts must be tightened. When testing the pump on the ground, water must be filled into the pump chamber to lubricate the rubber bearings. The instant start time shall not exceed one second to check whether the steering is correct. Pay attention to safety when the pump is upright to prevent toppling and injury. Strictly in accordance with the provisions of the pump lift and flow range, to prevent the pump with a large flow at low lift or produce a large pull at high lift, resulting in extreme wear of thrust bearings and other parts, the motor overload and burn. After the pump into the well, the measurement of the motor to the ground insulation resistance should not be less than 100MΩ. After starting, regularly observe the voltage and current, and check whether the motor winding insulation meets the requirements; if the pump storage temperature below freezing point, should be drained to prevent the water in the motor cavity from freezing and cause the motor damage due to low temperature.

The pump part is mainly composed of pump shaft, impeller, shunt shell, rubber bearing, check valve body (optional) and other components. The motor part is mainly composed of base, pressure regulating diaphragm, thrust bearing, thrust plate, lower guide bearing seat, stator, rotor, upper guide bearing seat, sand ring, water inlet section, lead cable and other components.

Awọn ẹya akọkọ ti ọja naa pẹlu:

1. 1.The motor is a water-filled wet submersible three-phase asynchronous motor. The motor cavity is filled with clean water, used to cool the motor and lubricate the bearing. The pressure regulating diaphragm at the bottom of the motor is used to adjust the expansion and contraction pressure difference of the water in the body caused by the temperature rise of the motor.
2. 2. In order to prevent the sand particles from entering the motor, two sand seals are installed at the upper end of the motor shaft extension, and a sand control structure is formed by installing the sand ring.
3. 3. In order to prevent the pump shaft from jumping when starting, the pump shaft is connected with the motor shaft through a coupling, and the thrust bearing is installed at the bottom of the motor.
4. 4. The lubrication method of the motor and the pump bearing is water lubrication.
5. 5. The stator winding of the motor adopts high quality submersible motor winding wire with high insulation performance.
6. 6. The pump is designed by computer CAD, with simple structure and excellent technical performance.

• 1.After the submersible pump is installed, check the insulation resistance and three-phase conduction from the switch again, check whether the instrument and the connection of the start equipment are wrong, if there is no problem, the trial machine can be started, and observe whether the indicator readings of the instrument exceed the rated voltage and current specified on the nameplate after the start, and observe whether the pump has noise and vibration phenomenon. If everything is normal, it can be put into operation.
• 2. After the first operation of the pump for four hours, the motor should be shut down to test the thermal insulation resistance quickly, and its value should not be less than 0.5 megaohm.
• 3. After the pump is shut down, it should be started after five minutes to prevent the water column in the pipe from being completely reflowed and causing excessive motor current and burnout.
•  
• 4.After the pump is running normally, in order to prolong its service life, it is necessary to check the power supply voltage, running current and insulation resistance regularly to see if they are normal.If the following conditions are found, the equipment should be shut down immediately to troubleshoot.
• (1)Under the rated working conditions, the current exceeds 20% of the rated value.
• (2)The dynamic water level drops to the inlet part, resulting in intermittent water discharge.
• (3)The submersible pump vibrates violently or emits noisy noise.
• (4)The power supply voltage is lower than 340 volts.
• (5)A fuse is burned out.
• (6)The water pipe is damaged.
• (7)The thermal insulation resistance of the motor to the ground is less than 0.5 megaohm.
• These inspections will help to ensure the normal operation of the pump, improve its reliability and stability, so as to ensure its durability and service life.
•  
• 5.unit disassembly:
• - untie cable rope, remove the pipeline part, remove the wire plate.
• - dabaru boluti omi, fi omi sinu iyẹwu motor.
• - remove the filter, loose the fixed screw on the coupling fixed motor shaft.
• - screw down the bolt connected with the motor at the inlet junction, separate the pump and the motor (pay attention to the unit cushion when separating, prevent the bending of the pump shaft)
• - pump disassembly sequence is: (see figure 1) inlet junction, impeller, guide housing, impeller...... check valve body, when removing the impeller, use special tools to loosen the conical sleeve of the fixed impeller first, avoid bending the pump shaft and each part in the disassembly process.
• - motor disassembly process is: (see figure 1) place the motor on the platform, remove the nut, base, shaft head lock nut, thrust plate, key, lower guide bearing seat, double head bolt from the bottom of the motor in turn, then take out the rotor (pay attention not to damage the wire package) and finally remove the connecting section and upper guide bearing seat.
• - unit assembly: Before assembly, the rust and dirt of the parts should be cleaned, and the mating surfaces and fasteners should be coated with sealant. Then they should be assembled in the reverse order of disassembly (the up and down momentum of the motor shaft is about 1 mm after assembly). After assembly, the coupling should be flexible, and then the filter screen test machine.
•  
• 6.The submersible pump should be dismantled and repaired according to Article 5 for each operation year, or less than one year, but the submersible time has reached two years, and the worn parts should be replaced.
