Problems solved by technology

[0002] At present, due to the medium such as dimethyl ether, the lubricity itself is not good. Generally, the single-stage vane pump for dimethyl ether vehicles has poor stability in use, often occurs shaft holding, and the skeleton seal is damaged, which reduces the use time and increases the maintenance cost. The application and promotion of energy causes difficulties

Abstract

The invention discloses a single-stage blade pump for dimethyl ether vehicles, comprising a blade, a shaft pin screw, a screw, an end cover, a pump cavity, an oil-taking ring, a small oil passage, a pump body shaft sleeve, a framework seal, a retainer ring, a snap spring, a shaft, an oil-outlet cavity. A swirl oil line is arranged on the inner surface of the pump body shaft sleeve axially; and bythe swirl oil line, the quantity of lubrication oil between the shaft and the pump body shaft sleeve is improved, the problems of easy occurrence of shaft clasping of the single-stage blade pump and short service life of the framework seal are solved, and reliable equipment guarantee for taking dimethyl ether as the fuel for vehicles to replace diesel is provided.

Description

Technical field: [0001] The invention relates to a single-stage vane pump, which is a single-stage vane pump suitable for dimethyl ether vehicles. Background technique [0002] At present, due to the medium such as dimethyl ether, the lubricity itself is not good. Generally, the single-stage vane pump for dimethyl ether vehicles has poor stability in use, often occurs shaft holding, and the skeleton seal is damaged, which reduces the use time and increases the maintenance cost. The application and popularization of energy causes difficulties. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a single-stage vane pump with a helical oil line in the pump body bushing to improve the lubrication effect between the shaft and the pump body bushing, and the skeleton oil seal is suitable for dimethyl ether The material used reduces the corrosion of dimethyl ether and improves the stability of the single vane o...
