Description

A kind of centrifugal pump manual exhauster and centrifugal pumping apparatus

Technical field

The invention belongs to centrifugal pumping apparatus technical fields more particularly to a kind of centrifugal pump manual exhauster and centrifugal pump to set It is standby.

Background technique

Centrifugal pump usually has the gas accumulated in direct work inside pump case exists, because atmospheric density is smaller, therefore leaf The centrifugal force generated also very little is taken turns, impeller center just only has faint negative pressure, and negative pressure at this time is not enough to suck liquid, from The suction inlet of heart pump also can not just form vacuum, will generate air sinuses phenomenon, cause impeller to dally so as to cause centrifugal pump damage It is bad, so before centrifugation pump startup all interior gas discharge must will be pumped in pump case and suction hose inner filling water.

And it solves problem above at present and mainly has three ways, such as and is following:

The first is washed by water in assembly bottom valve portion, and bottom valve is the inlet that check valve is located at water inlet pipe, but this method pair Loss caused by bottom valve head is larger, reduces the working efficiency of water pump；

Second is to install a drainage tank additional, and drainage tank is between water pump and water source, using preceding by drainage tank and centrifugation Topped up with water in pump will cause the very billow of water resource although the simple diversion tank volume of operating method is larger, at high cost Take；

The third is using large-scale vacuum air extractor, which is easily damaged and is difficult to repair, internal in use process It is easy that there are air, it is difficult to which Self-discharged needs manually to dredge, if things go on like this will cause the loss of machine, water pump is caused to start When, the case where not taking out water can be generated, working efficiency is reduced.Each product is using preceding requiring that manually liquid will be filled in pump case Then body restarts power supply and works, cause to be artificially infused to that program is cumbersome, and working efficiency is low every time.

Summary of the invention
