Abstract
The invention relates to a slurry pump for a swirler for preventing impurity in a pump from impacting a vane wheel. The slurry pump mainly comprises a bearing frame, a pump body is arranged at one end of the bearing frame, and the end surface of the pump body is connected with a pump cover through a bolt; a rotating shaft is arranged in the bearing frame, the vane wheel is arranged at one end of the rotating shaft, and the vane wheel is positioned in the pump body. The slurry pump is characterized in that a guard plate is connected to the inner wall of the pump cover. The slurry pump has the benefits of simple and compact structure and high stability, and is suitable for pumps with heavy calibres. Through the regulation of a gap between the position of the guard plate and the vane wheel, and the regulating amount can reach more than 10 mm, so that the working efficiency of the pump is effectively improved, and at the same time, the service lives of flow passage components are prolonged.
Description
Technical field:
The present invention relates to pump technical field, be specifically related to a kind ofly avoid the cyclone separator Pulp pump that in pump, impurity and impeller clash into.
Background technique:
Pulp pump weares and teares comparatively fast in running, especially the damage in impeller as revolving part is particularly serious, after wearing and tearing, the gap of impeller and backplate increases, the volumetric efficiency of pump significantly declines, common Pulp pump can control the gap between impeller and apron plate to a certain extent by the distance of adjustment rotating shaft, but because the distance of structural limitations rotating shaft adjustment is generally limited in 3-5mm, can not meet the demands in a lot of occasion
Summary of the invention:
Technical problem to be solved by this invention is the defect overcoming prior art, provides a kind of and avoids the cyclone separator Pulp pump that in pump, impurity and impeller clash into.
Technical problem to be solved by this invention realizes by the following technical solutions.
A kind ofly avoid the cyclone separator Pulp pump that in pump, impurity and impeller clash into, mainly comprise bracket, bracket one end is provided with the pump housing, pump body end surface is bolted pump cover, rotating shaft is provided with in bracket, rotating shaft one end is provided with impeller, and impeller is positioned at pump body, it is characterized in that: described pump cover inwall is connected with backplate.
Described backplate is parallel with impeller.
Described pump cover is provided with mounting hole, is provided with bolt in mounting hole, and backplate is connected with pump cover bolt.
Described mounting hole and bolted joint reach hydraulic seal.
Beneficial effect of the present invention is: 1). structure is simple, compact, good stability, is applicable to Application of Large-diameter Pump, 2). backplate is adjustable, and regulated quantity is larger, Pulp pump weares and teares comparatively fast in running, especially the damage in impeller as revolving part is particularly serious, after wearing and tearing, the gap of impeller and backplate increases, the volumetric efficiency of pump significantly declines, common Pulp pump can control the gap between impeller and apron plate to a certain extent by the distance of adjustment rotating shaft, but because the distance of structural limitations rotating shaft adjustment is generally limited in 3-5mm, can not meet the demands in a lot of occasion, the design can by regulating the gap between backplate positioning control backplate and impeller, and adjustment amount can reach more than 10mm, the working efficiency of effective raising pump, improve the working life of flow passage components simultaneously.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Embodiment:
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
As shown in Figure 1 a kind of avoids the cyclone separator Pulp pump that in pump, impurity and impeller clash into, mainly comprise bracket 1, bracket one end is provided with the pump housing 2, pump body end surface is bolted pump cover 3, rotating shaft 4 is provided with in bracket, rotating shaft one end is provided with impeller 5, and impeller is positioned at pump body, wherein pump cover inwall is connected with backplate 6.
Wherein backplate is parallel with impeller.
Wherein pump cover is provided with mounting hole, is provided with bolt in mounting hole, and backplate is connected with pump cover bolt.
Wherein mounting hole and bolted joint reach hydraulic seal.
More than show and describe basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
