deep well submersible pump
There are six common faults in the use of deep well submersible pumps:
1. The deep well submersible pump cannot pump water or the head is seriously insufficient: At this time, the pump does not rotate when it rotates, and when the deep well submersible pump is idling, there is still a lot of noise. Most of this phenomenon is that the bearing of the deep well submersible pump is damaged.
2. Poor sealing: The shaft extension end of the deep well submersible pump motor has a double-end mechanical seal part, which is made of high wear-resistant materials. After the deep well submersible pump has been used for a period of time, the seal is not well sealed due to wear or natural aging. And oil leaks. In addition, each mechanical mating surface has a circular rubber sealing ring to form a gasket to prevent water from infiltrating the pump body. However, due to the high speed of the motor used in the deep well submersible pump, the end face of the mechanical seal will inevitably be severely worn in long-term use.
3. The water outlet pipe is damaged and leaked: the normal rotation sound of the impeller of the deep well submersible pump hanging in the deep well can be heard (the electric meter also rotates normally), but the water cannot be pumped or only a small amount of water comes out. The tube is damaged.
4. Pump stuck: The pump does not turn, but a humming sound can be heard, which is mostly because the impeller of the pump is stuck by a foreign object. For example, the high sand content of well water due to geological reasons can easily cause damage to the filter screen cover.
5. Electric leakage: Electric leakage is one of the common faults of deep well submersible pumps. The fault phenomenon is that when the guillotine knife is closed, the leakage protector in the power distribution room will automatically trip. This is due to the water in the deep well submersible pump. Winding leakage phenomenon.
6. Startup capacitor failure: a buzzing sound can be heard when the power supply is connected, but the deep well submersible pump motor does not rotate; at this time, if the impeller is gently moved and the deep well submersible pump can rotate immediately, it can be judged that the capacitor is damaged.
The deep well submersible pump will encounter some new problems during the operation. It is necessary to comprehensively analyze and judge the fault phenomenon, and formulate a reasonable maintenance plan to ensure the long-term and efficient operation of the equipment.
