Abstract

The antiwear cam rotor pump has several recesses homogeneously distributed in the inner surface of pump cavity, and antiwear metal strips embedded inside the recesses. Embedding antiwear metal strips to the inner surface of the pump cavity can raise the abrasion resistance of pump cavity greatly and increase the service life of the pump greatly.

Description

Anti-wear rotor pump
Technical field
The pump that the present invention relates to is especially for using the lobed rotor pump of carrying high viscosity medium in oil field, the chemical industry.
Background technique
Be used to carry the lobed rotor pump of viscous crude, by cooperating rotation work in the pump chamber of pair of cams rotor in the pump housing.The pump housing of viscous crude lobed rotor pump mainly is to adopt the cast iron materials manufacturing at present, its wear resistance is bad, at work because the friction effect of the impurity such as sand grains in the medium, pump chamber wall in the pump housing is easy to wearing and tearing, the matching gap of interior pump chamber of the pump housing and rotor is increased, the leakage rate of pump is increased.Therefore, greatly reduce the flow and the working pressure of pump, increased maintenance and user cost, reduced working life pump.
Summary of the invention
The objective of the invention is to improve, provide a kind of manufacturing easy, can effectively improve the lobed rotor pump of pump chamber wall wear resistance at the shortcoming deficiency of above-mentioned prior art.
The pump housing 1, pump cover 2, casing 3, driving shaft 4, driven shaft 5, driving shaft 4 and driven shaft 5 driving gears 41,51 have been the present invention includes, be arranged on the pair of cams rotor 6a, the 6b that also are installed in respectively in the pump chamber in the pump housing 1 on driving shaft 4 and the driven shaft 5, it is characterized in that uniformly on the pump chamber internal surface in the pump housing 1 offering some grooves, welding is embedded with antifriction metal (AFM) bar 7 in this groove.
The present invention improves the wear resistance of pump chamber internal surface by inlay antifriction metal (AFM) bar 7 on the pump chamber internal surface greatly, and its manufacturing is easy, has prolonged the working life of the pump housing 1 greatly, has fully reduced maintenance frequency and maintenance cost.
Description of drawings
Fig. 1 is an embodiment of the invention structural representation.
Fig. 2, the 3rd, the structural representation of the pump housing 1, wherein Fig. 3 is the A-A sectional view of Fig. 2.
Embodiment
The pump housing 1, pump cover 2, casing 3, driving shaft 4, driven shaft 5, driving shaft 4 and driven shaft 5 driving gears 41,51 have been the present invention includes, the pair of cams rotor 6a, the 6b that are arranged in the pump chamber in the pump housing 1 and are installed in respectively on driving shaft 4 and the driven shaft 5 constitute, pump chamber internal surface in the pump housing 1 be pump chamber in uniformly on the hole face 21, bottom surface 22, two dead axle periphery 23a, 23b offer some grooves, in this groove, use the welding rod built-up welding of high-abrasive material, polish then, form the antifriction metal (AFM) bar 7 that is embedded on the pump chamber internal surface.Its manufacturing is easy, and the wear resistance of pump chamber internal surface is improved greatly.
