Description
Technical field
The utility model relates to Pulp pump technical field, more particularly, and particularly a kind of abrasion-proof slurry pump.
Background technique
In the industries such as mine, metallurgy, electric power, coal, the remote brute force conveying of material is very general, and especially in heavy media coal separation system, due to medium pipeline conveying is the dielectric suspensions that hardness is large, abrasiveness is strong, general employing be that Pulp pump is carried, but general Pulp pump is owing to carrying these raw materials, and its working life is all very short, need often to change Component, not only consume very large manpower and materials, but also often stop, cause manufacturing efficiency low.For this reason, be necessary to design a kind of abrasion-proof slurry pump.
Model utility content
The abrasion-proof slurry pump that the purpose of this utility model is to provide a kind of and increases the service life, enhances productivity.
In order to solve problem set forth above, the technical solution adopted in the utility model is: a kind of abrasion-proof slurry pump, comprise impeller, pump cover, the pump housing and pump shaft, described pump cover is installed on the pump housing, described impeller is installed between pump cover and the pump housing by pump shaft, the inner side of described pump cover is also provided with apron plate, the inner side of the described pump housing is also provided with rear backplate, also sheath is provided with between described apron plate and rear backplate, described impeller is positioned at the space that apron plate, rear backplate and sheath surround, and described apron plate, sheath and rear backplate all adopt high-abrasive material to make.
According to a preferred embodiment of the present utility model: also comprise the decompression lid coordinated with the pump housing, described decompression is covered on the pump housing between pump shaft, described decompression lid also matches with rear backplate.
According to a preferred embodiment of the present utility model: be also provided with axle sleeve between described decompression lid and pump shaft, between described decompression lid and axle sleeve, be provided with Sealing.
According to a preferred embodiment of the present utility model: described apron plate and rear backplate are all installed on the inner side of pump cover and the pump housing respectively by bolt assembly.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts the apron plate of high-abrasive material, sheath and rear backplate by arranging, avoid medium directly to contact with pump cover, the pump housing, greatly improve the wear resistance of Pulp pump, extend its working life, improve its manufacturing efficiency.
