Description

Quick processing apparatus that industrial pump entry bottom valve is closed not tightly

Technical Field

The utility model relates to a water pump fault handling technical field specifically is an industry pump entry bottom valve closes quick processing apparatus not tight.

Background

In industrial production, some equipment needs to be cooled frequently, and a common cooling method is to pump up water in an industrial water tank by using a double-suction centrifugal water pump to boost the pressure and then provide cooling water for other equipment. When the water pump is stopped, the water in the water pump inlet pipe and the pump body can flow in the instantaneous reverse direction, the two valve plates of the bottom valve are impacted to be closed, the water injection valve is opened to inject water to the pump inlet, the pump body and the inlet pipeline are continuously guaranteed to be full of water, and the water pump is in a normal standby state. Sometimes, after the water pump is stopped, the valve plate of the bottom valve of the water pump is blocked due to foreign matters between the rotating shaft and the hole, so that the bottom valve is not closed tightly, the pump body is not filled with water, and the water pump is started again to cause the water-pumping failure. The water pipe, the bottom valve and the filter screen need to be hung out together when the water-free fault is treated, which is laborious and time-consuming, and because the inlet pipeline is thick and long and the space is relatively narrow, the safety risk exists during the treatment.

Based on this, the utility model designs an industry pump entry bottom valve closes not tight quick processing apparatus to solve the above-mentioned problem.
