The motor is filled with clean water, and the special wear-resistant sleeve with water as the medium (no grease and no pollution). The impeller group is made of stainless steel 304, which is corrosion-resistant, wear-resistant, energy-saving and environmentally friendly, suitable for extracting underground drinking water, fountains, seawater, and can also be used for beverage, food, petrochemical industry, marine fire protection, etc.
1, power supply: three-phase AC 380V (tolerance + / - 5%), 50HZ (tolerance + / - 1%).
2, water quality:
(1) water temperature is not higher than 20 °C;
(2) solid impurities content (mass ratio) is not greater than 0.01%;
(3) PH value (pH) 6.5-8.5;
(4) hydrogen sulfide content is not greater than 1.5mg/L;
(5) chloride ion content is not greater than 400mg/L.
3, the motor is closed or water-filled wet structure, before use the submersible motor cavity must be full of clean water, to prevent false full, and then tighten the water injection, air release bolts, otherwise not allowed to use
4, submersible pump must be completely submerged in the water, the diving depth is not greater than 70m, the bottom of the submersible pump from the bottom of the well is not less than 3m.
5, the well water flow should be able to meet the submersible pump water output and continuous operation, the submersible pump water output should be controlled at 0.7 - 1.2 times the rated flow.
6, the well should be straight, the submersible pump can not be used or dumped, only vertical use.
7, the submersible pump must be matched with the cable according to the requirements, and the external overload protection device. 8, the pump is strictly prohibited without water no-load test machine

1, well submersible pump for clean water pump, prohibit the new well, pumping sediment and muddy water,
2, well water pump voltage grade of 380/50HZ, the use of other voltage grades of submersible motors need to be customized. The underground cable must use waterproof cable, must be equipped with starting equipment, such as distribution box, start not ready should have commonly used motor comprehensive protection function, such as short circuit overload protection, phase protection, undervoltage protection, grounding protection, idling protection, in case of abnormal conditions, the protection device should be timely action trip.
3, the installation and use of the pump must be reliably grounded, prohibit the push and pull switch when the hands and feet are wet, the installation and maintenance of the pump must be cut off the power supply, the use of the pump place to set up "to prevent electric shock" obvious signs:
4, down the well or before installation, the motor cavity must be filled with distilled water or non-corrosive clean cold boiling water, tighten the / water bolt, the pump on the ground test run, must be to the pump chamber water lubrication rubber bearings, instant start not more than a second, see whether the steering is the same as the steering instructions. When the pump is upright, pay attention to safety, prevent overturning injury.
5, strictly according to the provisions of the pump lift, flow range of use, to prevent low flow or high lift pumping force, the thrust bearing and other parts of the wear, the motor overload burned
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.
This product is a submersible pump. After installation, the insulation resistance and three-phase continuity should be rechecked to ensure the connection between the instrument and the starting equipment.If everything is normal, the machine can be tested. After starting, observe whether the readings of the instruments are correct. If the rated voltage and current beyond the nameplate, pay attention to whether the pump has noise or vibration.If everything is normal, it can be put into operation. After the first operation for four hours, the pump should be closed and the motor thermal insulation resistance test should be carried out quickly, and the value should not be less than 0.5 megaohm. After stopping the pump, it is necessary to restart it at an interval of five minutes to prevent the water column in the pipeline from completely reversing, causing excessive current and burning the motor. After normal operation, the power supply voltage, running current and insulation resistance should be checked regularly. If abnormal conditions are found, the machine should be stopped immediately to troubleshoot. When disassembling, it is necessary to untie the cable rope, remove the pipeline part, remove the line protection plate, and dry all the water in the motor cavity side by side. The disassembly sequence includes taking off the filter element, loosening the bolt of the coupling fixed to the motor shaft, unscrewing the bolt connecting the water inlet and the motor, separating the pump and the motor (pay attention to keeping the unit level when separating to avoid bending the pump shaft) and other steps. For motor disassembly, it is necessary to remove the nut, base, shaft head lock nut, thrust plate, key, lower guide, bearing seat, screw (pull rod screw), take out the rotor, and finally take out the connection part and upper guide bearing seat. When assembling the unit, it is necessary to clean the rust and dirt of each part, apply sealant and assemble in reverse order according to the disassembly. When running once a year or the operation time is less than one year but the immersion time is two years, it is necessary to disassemble and inspect in accordance with the provisions and replace the worn parts. Storage needs to empty the water in the motor cavity, pay attention to the anticorrosive wire mesh plate and tie the cable, stored in a room with a temperature below 40 DEG C and no corrosive substances and gases, and pay attention to rust prevention when not used for a long time.
