Product overview of oil-filled submersible pumps in Fengxian District, Shanghai
Model oil-filled submersible pumps (hereinafter referred to as electric pumps), implementation standards, production license numbers. The electric pump consists of three parts: a water pump, a seal and an electric motor. The water pump is located on the upper part of the electric pump and has a centrifugal or axial flow structure. The motor is located at the bottom of the electric pump and is an oil-filled three-phase asynchronous motor. The water pump is sealed with an integral mechanical seal box between the motors. Each fixed stop seal is sealed with a shaped oil-resistant rubber seal ring for static sealing.
Submersible electric pumps work underwater. It is compact and lightweight, does not pump water from the well and does not require a long drive shaft. Therefore, submersible electric pumps are very suitable for rural well water irrigation. The most widely used type is the B-type submersible electric pump. This kind of submersible electric pump uses waterproof measures such as mechanical seals or air seals to keep the inside of the motor dry and free from water intrusion. Pay attention to the following points when using:
Check whether the seals on the air vent, water drain, oil drain hole and cable joint of the pump are loose. If they are loose, they must be tightened.
Use a voltmeter to check the insulation resistance. It should be no less than . megohm. If it is lower than this value, open the water and vent holes for drying or sun-drying.
Check the cable. If it is cracked or broken, it should be replaced to avoid leakage.
Before starting, check all circuits and switches to see if the wiring is correct and secure. Then let it idle for 3 to 3 minutes on the ground (the time should not be too long to avoid damaging parts or burning the motor windings), and check whether the motor is rotating in the correct direction. If there are no problems as mentioned above, it can be put into water for use.
When the submersible electric pump is put into the water for use, the cable must not be stressed. It should be tied to the wooden frame at the wellhead with a rope. The maximum depth that the electric pump can be put into the water is 3 meters, and the minimum depth is . meters (from the center of the impeller).
During operation, changes in water level in the well should be frequently observed. The motor must not be exposed to the water or sink into the mud, so as not to affect the heat dissipation of the motor and burn the windings. The electric pump should be raised and lowered at any time as the water level in the well changes. If the water volume decreases or is interrupted, the cause should be immediately identified or shut down for inspection. The cable must not rub against the well wall to prevent well water from seeping into the motor along the cable core after the cable is worn out.
For new or replaced submersible pumps with integral sealing boxes, after using them for hours, you should check whether the sealing is in good condition. In the future, check once a month. Also check whether the sealing of the shielding sleeve between the motor rotor and stator is in good condition.
After one year of use, the pump should be inspected for corrosion, removed and painted.
If the submersible electric pump will not be used for a long time, it should be carefully inspected and stored in a dry and ventilated house.
