Deep well submersible pumps common faults

Today, by the Shanghai Weihu submersible pump manufacturers for everyone to explain wells with submersible pump common faults.
(1) can not carry out pumping work, or a serious shortage of head affect the work: when the wells with submersible pumps will appear when the turn does not turn the phenomenon, and wells with submersible pumps in idling, there is a large noise, which Most of the phenomena are deep well submersible pump bearing damage.
(2) bad seal: well submersible pump motor shaft extension of the end of a double-end mechanical seal parts, this component is made of high wear resistance of the material made of deep well with submersible pump in the use of a section After the time, the seal due to wear or natural aging caused by poor sealing and oil leakage. In addition, in the mating surface of each machine, are equipped with a circular rubber seal, as a gasket protection to prevent water from penetrating into the pump body, but because the deep well with submersible pump motor speed is very high, if long-term use Will cause serious wear on the mechanical seal face.
(3) outlet pipe leakage leak: can hear the wells hanging in the deep wells with submersible pump pump wheel normal sound (the meter is also normal rotation), but not pumping water or only a small amount of water, this situation Most of the pipes that are out of water are damaged.
(4) card pump: the pump does not turn, but can hear the buzzing sound, which is mainly because the foreign body will pump the impeller stuck. For example, due to geological causes of well water quality sediment concentration, this situation is likely to cause damage to the filter cover.
(5) leakage: leakage is one of the most common failure of submersible pumps, the main phenomenon is that when the gate is closed, the distribution room in the leakage protection device will automatically trip, which is due to well Submersible pump pump body water and cause the motor winding leakage phenomenon.
(6) start capacitor failure: connected to the power can hear the buzzing sound, but the well with submersible pump motor does not turn; this time if we gently toggle the impeller, well with the submersible pump if you can immediately turn It is judged that the capacitor is damaged.
