Description

Technical Field

[0001] The utility model relates to the field of pump casings, in particular to an explosion-proof hydraulic vane pump casing. Background Art

[0002] The hydraulic vane pump is a common hydraulic transmission element, mainly composed of a pump body, vanes, rotor, shaft and housing. The vanes move inside the rotor, causing the volume of the pump chamber to change periodically, thereby sucking in and squeezing out liquid. Hydraulic vane pumps are usually used in hydraulic systems that require higher pressure and larger flow, such as construction machinery, agricultural machinery, aerospace and industrial equipment.

[0003] The pump casing of a hydraulic vane pump usually consists of a pump housing, an end cover and a flange plate. The end cover is installed on the end of the pump housing by bolts, and the pump housing can be installed at a designated position through the flange plate for operation. When the pump housing is produced, the pump housing and the flange plate are cast as one piece. Since the pump housing is cast as one piece, its overall pressure resistance and explosion-proof performance can be improved. However, when the pump housing is installed at a designated position through the flange plate for use, the top or bottom of the pump housing is subject to collision impact, which can easily cause the pump housing to rupture, thereby reducing its overall explosion-proof performance. It is inconvenient to protect the top and bottom of the pump housing when the pump housing is installed through the flange plate. Utility Model Content
