ZYB high-pressure gear oil pump 8 factors cause no oil or insufficient flow because many materials are cast iron or plastic. If only ZYB high-pressure gear oil pump made of these materials is used, it is difficult to meet the needs of customers, if there is a lot of corrosion Sexual medium can not be discharged, such as sulfuric acid, hydrochloric acid, nitric acid, etc.; this is one of its characteristics. ZYB high-pressure gear oil pump 8 factors cause no oil or insufficient flow. ZYB high-pressure gear oil pump causes 8 factors that cause no oil or insufficient flow. Because there are many materials that are cast iron or plastic, if you only use these materials to make ZYB high-pressure gear oil pump, it is difficult to meet the needs of customers. If there are many corrosive media, it can not be discharged, such as sulfuric acid, hydrochloric acid, nitric acid, etc. This is one of its features. Another feature is that it is resistant to high temperatures in addition to rust. Therefore, many manufacturers have produced high-temperature resistant stainless steel "target=_blank> stainless steel high-pressure gear oil pump. Although it is stainless steel "target=_blank> stainless steel, but there are a lot of auxiliary materials can not withstand much high temperature, generally within 120 ° is no problem, If some chemical plants need to withstand more than 200 degrees of high temperature, they still have to choose a centrifugal pump.

1. ZYB high-pressure gear oil pump often has insufficient flow or no oil during operation. The main reasons are:
(1) The installation height of the oil pump is too high, so that the impeller immersion depth is not enough, resulting in a decrease in the oil output of the oil pump;
(2) The oil pump turns to the opposite direction;
(3) The oil outlet valve cannot be opened;
(4) The oil discharge pipe is not smooth or the impeller is blocked;
(5) The wear ring at the lower end of the oil pump is seriously worn or blocked by debris;
(6) The liquid density of the pumping liquid is too large or the viscosity is too high;
(7) The impeller is detached or damaged;
(8) When multiple oil pumps share the output of the pipeline, the one-way valve is not installed or the one-way valve is not tightly sealed.
2. Exclusion measures (1) Control the allowable deviation of the installation height of the oil pump, and do not expand at will;
(2) Before the oil pump is tested, the motor is idling, and the steering is checked to make it consistent with the oil pump. If the above situation occurs during use, check whether the power phase sequence changes.
(3) Check the valve and maintain the valve frequently;
(4) Clean up the blockage of the pipeline and the impeller, and Botaibang often salvage the debris in the oil storage tank:
(5) Clean up debris or replace the wear ring;
(6) Look for the cause of oil quality changes and treat them;
(7) Reinforce or replace the impeller;
(8) Add or replace the one-way valve after checking the cause.
