Description

Quick exhaust device for self-priming pump

Technical Field

The utility model belongs to the technical field of self-priming pumps, and particularly relates to a quick exhaust device for a self-priming pump.

Background

In some water treatment systems, water is required to be taken from a low-water-level water source, the self-priming pump is widely applied to the self-priming centrifugal pump, and the self-priming pump has the advantages of compact structure, convenience in operation, stable operation, easiness in maintenance, high efficiency, long service life, stronger self-priming capability and the like, and can be used for self-priming pumps of different materials by only ensuring that quantitative liquid is stored in the pump body before working. The working principle of the self-priming pump is that water is filled in the pump shell before the water pump is started (or water is stored in the pump shell). After the impeller is started, the impeller rotates at a high speed to enable water in the impeller channel to flow to the volute, at the moment, the inlet forms vacuum, so that the water inlet check valve is opened, and air in the suction pipe enters the pump and reaches the outer edge through the impeller channel.

Because all self priming pumps need to be added with water diversion to discharge air in the pump when starting, the problem is that: the discharged water flow is mixed with air to spray out too fast, on one hand, the effect of atmospheric pressure alone is utilized to not carry out effective gas-liquid separation, and the self-priming pump is easy to corrode by forming gas foam, on the other hand, the exhaust speed can not be adjusted to adjust the internal air pressure.
