Description
Technical field
The present invention relates to fluid machinery, be related specifically to a kind of internal-mixing self-priming pump with flap valve return port.
Background technique
Self-priming pump belongs to self priming centrifugal pump, it have compact structure, easy to operate, operate steadily, safeguard easily, efficiency is high, the life-span is long, and have the advantages such as stronger suction capacity, self-priming pump need not be poured water before starting, operate through the section time, by the effect of pump self, water can be drunk up, normal operation input, and reflux is a critical component of internal-mixing self-priming pump, how to ensure effective backflow of reflux during pump startup, and when preventing pump from running well, the backflow of reflux is a key issue relating to self-priming pump self-priming performance.Conventional backflow device is just provided with reflux valve to ensure the normal work of reflux, but the problem such as backflow when can not effectively stop pump normally to work, have impact on pump performance.
Summary of the invention
For solving the problem, the present invention adopts a kind of internal-mixing self-priming pump with flap valve return port to solve above problem.Flap valve is equipped with in return port (3) outlet port, can ensure self-priming performance during pump startup, can effectively stop again liquid medium in the backflow at return port place, strengthens self-priming performance and the efficiency of pump.
Realizing the technological scheme that above-mentioned purpose adopts is: flap valve is mainly installed on the tail end of drainage pipe, has the check valve preventing outer water from pouring in down a chimney function.Flap valve is formed primarily of valve seat, valve plate, Mi Tufengquan, hinge four part.Proterties is divided into circular and square.The material of flap valve is various fabricated metals traditionally, has developed into multiple composite material now.
According to above principle, adopt a kind of internal-mixing self-priming pump with flap valve return port, this self-priming pump comprises liquid storage room (1), reflux valve (2), return port (3), fill hose joint (4), the pump housing (5), titting water outlet (6), air-water separation chamber (7), volute casing (8), impeller (9), mechanical seal (10), bearing body part (11), the main structures such as suspension strut (12), its major character is: flap valve is equipped with in return port (3) outlet port, can effectively stop liquid medium in the backflow at return port place, its reflux is primarily of return port (3), flap valve (14) and reflux valve (2) composition, flap valve is primarily of valve seat, valve plate, Mi Tufengquan, hinge four part is formed, during pump startup self-priming, flap valve (14) is opened, during pump normal working, flap valve (14) is closed, flap valve (14) adopts aluminum alloy material, aluminum alloy density is low, intensity is high, the flap valve of less quality is conducive to backflow during pump self-priming.
The invention has the beneficial effects as follows: the use of flap valve well solves reflux problem when self-priming pump runs well, and the self-priming performance of pump is good, and the efficiency of self-priming pump increases.
The present invention tries out through user, and reaction effect is good.
