Reason analysis of self priming pump with long self-priming time

All kinds of self suction pump has self-priming performance are different in the use of all kinds of self suction pump products are often encountered in the self-priming pump self-priming process takes a long time to suck water, such as auto suction time is too long will delay the emergency rescue and production need to use emergency drainage or water production, so we it is necessary for everyone to share a self-priming pump self-priming time is too long and the reasons of self-priming pump self-priming time is too long for the solution for reference:

Self priming pump self suction causes too long is likely to import pipeline leakage phenomenon is minor, the self-priming time is too long after the solution of a self suction pump filled with water running 5 minutes to ensure quiet environment there is no air inlet pipe close to the ears to listen to the sound of a suspected leak point. Because after the pump running for a period of time will form a negative pressure in the import, after shutdown if leakage in the case of the negative pressure pipe outside the air inlet pipe to the inside.

Because it is a self-priming pump self suction causes long time self-priming pump inlet pipe length caused by, because there is too long the air inlet pipe after pipe, self suction pump to the inlet pipe of the air inlet pipe net after formation of negative pressure suction to water inlet pipe is too long so the air will be a lot of self suction pump the exhaust will take some time to drain, the self-priming time is too long the solution is to reduce the vacuum self suction pump inlet pipe or switch to our self suction pump can solve the problems

Because of the curved pipe of the imported pipeline, especially when the imported tube is used, it is easy to appear, and the solution can straighten the inlet pipe. There is a self-priming pump self suction causes too long because of self suction pump outlet pipe end submerged in the liquid inside the pump suction air to take them very difficult due to the self-priming pump self-priming time is too long the solution is to expose the end of the air outlet pipe in the air discharge.

It may also be the self priming pump cavitation phenomenon caused by the high temperature of the self priming pump. The solution for such self priming pump is too long to absorb the liquid, or to fill the pump body with cold water before starting.

The suction pipe is larger than the pump caliber, which will cause the suction time of the self priming pump too long. Because the inlet pipe will reduce the self suction ability of the self priming pump after the increase of the inlet pipe. It is advisable to choose the pipeline matching the self suction pump inlet.

If you are using a self suction centrifugal pump products to convey the particles containing sewage started self-priming time soon, and after a period of time is likely to be slow, the pump body suffered blocking phenomenon, the self-priming pump self-priming time is too long, the solution can only be replaced Self-priming sewage pump the product right.
