Single stage centrifugal pump without water or low pressure and the use of centrifugal oil filter

　　No pumping fault of centrifugal pump: no pressure or low pressure at pump outlet after single-stage centrifugal pump starts

　　Cause analysis:

　　1) . before starting the pump, the pump body is not drained, the system is not full of water or the system leaks seriously

　　2) , pump inlet and outlet water channels are blocked.

　　3) . motor reversal

　　Treatment method:

　　1) Before starting the pump, open the drain valve of the pump body and then fill the pump body with water. When the drain valve sees water, close the drain valve. If

　　In case of serious steam leakage in the system, the steam leakage shall be handled first and the pump shall be started.

　　2) Check whether there are sundries blocking the inlet and outlet flow channels of the pump.

　　3) . change the motor to positive transmission.

　　Preventive measures: the pump body shall be deflated in time during startup, inspection shall be strengthened, maintenance and problems shall be found in time.

　　Features of centrifugal oil filter:

　　◆ high filtering accuracy and strong ability to remove impurities

　　The centrifugal oil filter adopts multi-stage barrel filter, which has strong ability to remove impurities. The primary filter adopts the large flow cleanable filter element with high filtering efficiency, which can remove a large number of impurities in the oil. The "layered and gradually dense" high-efficiency fine filtering device has large scale capacity, high strength, long service life, and can remove the fine particles in the oil.

　　◆ strong ability to remove water and demulsify

　　This series of vacuum oil filter adopts the world's leading "cavitation" principle and coalescence separation technology, combined with the demulsification device of special polymer material, which can not only separate the liquid water and free water in the oil quickly and easily, but also remove the dissolved water in the oil. Can make emulsified lubricating oil clear

　　Transparent, meet the use requirements of hydraulic lubrication equipment.

　　◆ high degree of automation, safety and reliability

　　The control system of this series of vacuum oil filter for lubricating oil dehydration is safe and reliable. All the control appliances are imported products, and the advanced automatic liquid level control system, automatic overpressure protection system for filter element blockage alarm, automatic temperature constant control system, automatic condensate separation system, and automatic electrical protection control system are adopted. Make the operation simple, safe and reliable. It can also be equipped with computer full-automatic type according to the needs, which can realize man-machine separation operation.
