Description
Technical field
The utility model relates to liquor pump, especially a kind of pump housing in the liquor pump.
Background technique
The existing pump housing mainly adopts intermediate clapboard that the active chamber of pump body is divided into the first active chamber and the second active chamber, and the pump housing of this structure is because the design of intermediate clapboard so that processing technology is complicated, has reduced work efficiency.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and the pump housing that a kind of technique is simple, work efficiency is high is provided.
For achieving the above object, the utility model adopts a kind of pump housing, offers oil inlet hole and oil outlet on this pump housing, wherein, offer the work through hole on the described pump housing, described oil inlet hole is communicated with by filler opening between the through hole with work, and oil outlet is communicated with by oil outlet between the through hole with working.
The pump housing has been cancelled intermediate clapboard compared with the prior art, and intermediate clapboard is arranged on the mandrel, simplifies the processing technology of the pump housing, improves the work efficiency of the pump housing; Adopting the structure of moveable partition board is that arcuation matches so that be not easy leakage of oil with the inwall of rotor and the pump housing.
Wherein, described oil inlet hole and oil outlet all are positioned at the below of work through hole.
Wherein, described pump housing inwall between filler opening and oil outlet offers locating slot.
Wherein, the sectional shape of described locating slot is circular.
The utility model pump housing is compared with existing pump housing cancellation intermediate clapboard, and simplified processing process is guaranteed quality of processing, improves work efficiency, makes things convenient for pump sealed at both ends, improves the installation precision of pump.
