Pump body structure of self-priming pump with split liquid storage chamber and gas-liquid separating chamber

Abstract

The invention discloses a pump body structure of a self-priming pump in which a liquid storage chamber and a gas-liquid separation chamber are separated, which belongs to the pump structure. The pump body structure of the existing integrated self-priming pump is complicated, the casting process is poor, and the rejection rate of the pump body castings is low. High, low production efficiency, the pump body structure of the present invention is formed by connecting the inlet cavity and the pump body through fasteners, the inlet, flow channel, and liquid storage chamber are arranged on the inlet cavity, and the volute chamber, gas-liquid separation chamber, The return hole is set on the pump body. On the basis of satisfying the self-priming function of the self-priming pump, the pump body structure of the self-priming pump is optimized, the casting process of the pump body is improved, the reject rate of the pump body casting is reduced, and the production is improved. efficiency and reduce production costs.

Description

technical field [0001] The invention belongs to a pump structure, in particular to a self-priming pump body structure in which a liquid storage chamber and a gas-liquid separation chamber are separated. Background technique [0002] The traditional self-priming pump body structure is: an integrated pump body structure including a gas-liquid separation chamber, a volute, a liquid storage chamber and an S-shaped flow channel. The disadvantages are that the pump body structure is complex and the casting process of the pump body is poor. , the rejection rate of pump body castings is high, and the production [0003] The efficiency is low and the relative production cost is high. Contents of the invention [0004] The technical problem to be solved and the technical task proposed by the present invention are to overcome the defects of the existing integrated self-priming pump, such as the complex structure of the pump body, poor casting process, high rejection rate of pump bod...
