The quality of products is constantly improving. Here are some knowledge and difficult questions about diesel multistage pumps. I hope these problems and solutions can help you. The following is about how to improve the self-priming time of multistage pumps and how to improve the self-priming ability of multistage pumps.

As you may know, the length of the self priming time of the diesel multistage pump determines the size of the self priming capacity of the diesel multistage pump. So how to improve the self priming time of the multistage pump has become the focus of attention. The difference between the self - priming centrifugal pump and the general centrifugal pump is that it can be self - priming, so the operating characteristics of the pump are also determined by self - priming.

How to improve the self suction time of the diesel pump? When opening, the valve must be opened first, then the gas in the suction pipe of the multistage pump must start after the pump starts, so the valve must start and the gas can be discharged from the discharge port. At the same time, we should ensure that the pump cavity must have enough liquid. If there is no liquid in the self suction centrifugal pump chamber, no mixture of gas and liquid can be formed, nor can it be pumped.

Show in a number of experiments, the pumping capacity and pump multistage pump the liquid inside is very relevant, when the multi-stage pump liquid is less than 1.5L when the vacuum degree is very small, and the working state of the pump instability, air leakage into the pump, the cycle will not interrupt, continuous pumping. When the water in the pump is more than 2.OL, the back water is blocked by the tongue. The air will not leak in the pump, and then the gas is continuously pumped.

In order to ensure the reliability and speed of the pumping of the diesel pump, we should pour enough fluid into the pump cavity when starving, so that the time and speed of the pump will be increased. In this way, the working efficiency of the pump will also rise.
