6, after the pump down the well, the measurement of the motor to the ground insulation resistance should not be less than 100M, after the start to observe the voltage and current, check the motor winding insulation, whether in line with the requirements; pump storage location temperature if less than freezing point, should be dry the motor cavity water, prevent the motor cavity water ice damage caused by low temperature.

1.Structure brief: pump part is mainly composed of pump shaft, impeller, diversion shell, rubber bearing, check valve body (optional parts) and other components. The motor part is mainly composed of base, pressure regulating film, thrust bearing, thrust plate, lower guide bearing seat, stator, rotor, upper guide bearing seat, sand throwing ring, water inlet node, cable and other components

2.The main feature of this product is the use of water-cooled wet submersible three-phase asynchronous motor. The motor chamber is filled with water, used to cool the motor and lubricate the bearing. The voltage regulating film at the bottom is used to adjust the pressure difference caused by the temperature rise of the motor. In order to prevent the sand in the well water from entering the motor, two oil seals are installed on the top of the motor shaft extension end, and a sand throwing ring is installed to form a sand control structure. This design ensures the long-term reliability and stability of the motor, which is an ideal choice for pump users.

3. In order to prevent the pump shaft from running up when starting, the pump shaft and the motor shaft are connected by a coupling, and an upper thrust bearing is installed under the motor.

4.The lubrication of the motor and the pump bearing is water lubrication.

5.he motor stator winding is made of high quality submersible motor winding wire, with high insulation performance.

6. The pump is designed by computer CAD, with simple structure and good technical performance.

7. Cable joint, cut off a 120mm rubber sleeve from one end of the outgoing cable and the matching cable with an electrician's knifethen stagger the length of the three core wires in a stepped shape, peel off a 20mm copper core, scrape of the oxide layer on theoutside of the copper wire with a knife or sand cloth, and insert the two connected wire ends in palirs.After tying the layer tightly with fine copper wire, solder it thoroughly and firmly, and sand of any. burrs on the surface. Then, forthe three joints, use polyvester insulation tape to wrap them in a semi stacked manner for three lavers. Wrap the two ends of thewrapping layer tightywith nyion thread,and then use a semi stacked method to wrap the tape for three layers. Wrap the outellayer with high-pressure insulation tape for three layers. Finally, fold the threestrands together and repeatedly wrap them for fivelayers with high-pressure tape. Each layer must be tightly tied, and the interlayer joints must be tight and fimm to prevent water frompenetrating and damaging the insulation, After wrapping, soak in water at room temperature of 20 ’c for 12 hours, and measurethe insulation resistance with a shaking table, which should not be less than 100M Ω

1. (1)After installing the submersible pump, it is necessary to recheck the insulation resistance and three-phase continuity of the switch, and check whether there are errors in the connection between the instrument and the starting equipment. If there is no problem, the test machine can be started. After starting, observe whether the indication readings of the instruments exceed the rated voltage and current specified on the nameplate, and observe whether the pump has noise and vibration. If everything is normal, it can be put into operation.
2. (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. (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. (4)After the pump is put into normal operation, in order to prolong its service life, it is necessary to check whether the supply voltage, working current and insulation resistance are normal regularly. If the following conditions are found, the pump should be shut down immediately to troubleshoot.

 7 unit assembly: before assembly, the rust and dirt of the parts should be cleaned, and the mating surface and fasteners should be coated with sealant, and then assembled in the opposite order of disassembly (the momentum of the motor shaft is about one millimeter after assembly), after assembly, the coupling should be flexible, and then the filter screen test machine. 6. The submersible pump is known for its durability and efficiency, providing you with a lasting pumping solution. When the operating time is more than one year per year, or if the operating time is less than one year, but the immersion time is up to two years, it must be disassembled and inspected in accordance with Article 5 to replace the worn parts. This pump is well designed to ensure efficient operation and reliability, so that you can rest assured. Whether it is used for pumping water from a family pond or pumping water for agricultural irrigation systems, this product can meet your needs. Choose this high-quality pump to keep your pump system in the best condition at all times, ensuring smooth operation and extending its service life.
