Description
Technical field
The invention belongs to air-conditioning and manufacture field, it is more particularly related to the system of a kind of shielded electric pump electric machine casing
Preparation Method.
Background technology
The housing of the preparation method of prior art shielded electric pump electric machine casing typically uses metallic plate to make, this structure
During electric pump transporting low temperature medium, cause motor temperature relatively low because medium enters motor cavity, and the formation temperature difference of surrounding, from
And condense, typically can freeze at motor housing, condense in rosette, icing repeatedly, condensation, cause housing corrosion, not only shadow
Ringing outward appearance, even reduce rosette insulating properties, cause electric leakage or short circuit, housing and stator module are that split is arranged, both groups
After dress, tightness is strong, can shake in the course of the work, and noise is relatively big, housing that prior art metallic plate is made and wiring
Box, the magnetic residual that there is also metal material also produces the defect of eddy-current loss, and the cost of metal material is high, weight relatively moulding
Weight, the technology difficulty of assembling is big.
Summary of the invention
The technical problem to be solved is to provide a kind of light-weighted shielded electric pump electric machine casing convenient for assembly
Preparation method.
To achieve these goals, the technical scheme that the present invention takes is a kind of shielded electric pump electric machine casing of being provided
Preparation method, comprise the steps:
(1) plastic pellet of drying is put in injection machine；Plastic pellet drying time 2 ~ 3 hours, oven temperature is adjusted to 80 ~ 90 DEG C；
(2) after heating plasticizing, regulation injection temperature and pressure, injects injection mould in mold cavity by screw rod by molten plastic
Middle molding；Injection temperature is 170 DEG C ~ 200 DEG C；Injection pressure 30 50MPa；Cover half is heated to 70 ~ 80 DEG C, and dynamic model is heated to 50
~60℃；
(3) mold filling cooling；The time of cooling molding is 35s ~ 40s；
(4) open mould to isolate product and be positioned on conditioning beds and carry out shaping and repairing burr.
A kind of preparation method of shielded electric pump electric machine casing, plastic pellet be ABS plastic or phenolic resin, Lauxite,
The mixture of one or more in melmac, unsaturated polyester resin, epoxy resin, organic siliconresin, polyurethane.
Using technical scheme, use this technique to make shielded electric pump electric machine casing, the finished product of preparation has heat
The high fluidity of plastic material, applies when electric machine casing this complicated shape goods, can keep excellent physical characteristic and one-tenth
Type；It has good impact strength, excellent moulding processability, higher impact strength and case hardness, and heat becomes
Shape temperature is high, good stability of the dimension；The electric machine casing using this plastics to manufacture, facilitates the assembling of electric machine casing and the pump housing,
Meanwhile, use plastic, lightweight compared with the metal shell of prior art, meet light-weighted requirement.
Below with reference to embodiment, the present invention is described in detail.
