The raw materials is prepared, polyurethane performed polymer, PVA, MOCA and carborundum, polyurethane composite body sets up in the inboard of the pump body, regard the pump body as the skeleton, pours into a mould the raw materials to the inner wall of the pump body, then the solidification back drawing of patterns in 3 hours that keeps warm under 90~100 DEG C condition, and just the temperature was vulcanized under being 80~110 DEG C condition through 8~10 hours, polyurethane composite body sets up in the inboard of pump cover, the unanimity of pouring procedure and the pump body, with the pump body and the pump cover fixed connection that have a polyurethane composite body after the shaping. The utility model discloses simple structure, installation easy maintenance, light in weight still has the resistant cavitation characteristics of wear -resisting, corrosion -resistant, resistant oil simultaneously, and stability and reliability are high.
Description
Technical field:
The utility model is related to pump technical field, specifically a kind of centrifugal type slurry pump pump head and its manufacture method.
Background technology:
The pump head structure composition of the current Pulp pump of China is entirely pump case, pump cover, sheath, apron plate and rear backplate group
Become, with pump case, sheath, apron plate and rear backplate are wrapped, sheath, apron plate, rear backplate as flow passage components, in reality
Application in, flow passage components because of situations such as abrasion, corrosion it is therefore desirable to frequent maintenance and change flow passage components, and due to
The scope of operation of Pulp pump is mostly severe, the less poor environment in space, and is all metal casting part again, very heavy,
So maintenance and replacing flow passage components are very difficult, in prior art, the flow passage part of Pulp pump is generally two kinds of materials, a kind of
Alloy-steel casting, high another kind of is rubber structure part, and alloy components machining and Technology for Heating Processing complex although
Better than conventional cast steel and ironcasting on anti-wear performance, but in corrosion resistance, performance is not high, intolerant to cavitation, in addition existing
Have in technology using common rubber parts as liner thus improving the technology of its wearability, but the oil resistivity of rubber parts is relatively
Difference, easily aging, easily scratch rubber parts in solid particle, not wear-resisting, so effect is unsatisfactory.
Utility model content:
Technical problem to be solved in the utility model is to provide a kind of structure simple, convenient to install and maintain, lightweight,
Also there is wear-resisting, corrosion-resistant, the centrifugal type slurry pump pump head of oil resistant resistance to cavitation feature and its manufacture method simultaneously.
Technical problem to be solved in the utility model employs the following technical solutions to realize:
A kind of centrifugal type slurry pump pump head it is characterised in that: include the pump housing, pump cover, connecting plate and polyurethane compound body, institute
The pump cover stated is arranged on the rear side of the pump housing, and described connecting plate is arranged on the rear side of pump cover, and the described pump housing is passed through tightly with pump cover
Firmware is fixed together, and described polyurethane compound body is arranged on the inner side of the pump housing and pump cover.
Described polyurethane compound body is arranged for split, and is cast in the inner side of pump cover and the inner side of the pump housing respectively.
A kind of manufacture method of centrifugal type slurry pump pump head it is characterised in that: comprise the following steps,
1) raw material is prepared, and described polyurethane compound body is made up of following raw material, base polyurethane prepolymer for use as, pva, moca and carbon
SiClx；Moca is mocha.
2) polyurethane compound body is arranged on the inner side of the pump housing, first becomes the pump housing with die casting, then using the pump housing as skeleton, right
Raw material is poured into a mould by the inwall of the pump housing by solidification mould, and then under conditions of 90～100 DEG C, heat preservation solidification was carried out after 3 hours
The demoulding, then through 8～10 hours and temperature be 80～110 DEG C under conditions of vulcanize, obtain approved product after cooling；
3) polyurethane compound body is arranged on the inner side of pump cover, first becomes sheet metal pump cover with Making mold, then pump cover is made
For skeleton, pouring procedure is consistent with the inner side polyurethane compound body of the pump housing, obtains the approved product of pump cover；
4) pump housing with polyurethane compound body after shaping and pump cover are fixed together by securing member.
The pump housing in the utility model with traditional pump case, sheath and backplate in front and back effect so that traditional pump case, shield
Set and apron plate as end together with, replaced by the our pump housing.The utility model polyurethane compound body passes through certain bar
The manufacture of part is so as to produce chemical reaction, and curing molding, can firmly be bonded on the pump housing and the inwall of backplate, become
Integrally, stability and better reliability, noise is low.
The main body head of Pulp pump is set up separately by the utility model counts into two parts, only includes the pump housing and pump cover, will pass
The passage curve of system designs on the pump housing and pump cover, does not change the runner form within traditional pump head.
The beneficial effects of the utility model are: the utility model structure is simple, convenient to install and maintain, lightweight, also simultaneously
There is wear-resisting, corrosion-resistant, oil resistant resistance to cavitation feature, stability and reliability are high, long service life.
