Abstract

The invention discloses a kind of casting technique of the pump housing, the casting technique of the pump housing is comprised the following steps that：1）Make evaporative pattern；2）Evaporative pattern is packed into sandbox, using natural silica Sand filling in sandbox, the sandbox after filling placed on a vibration table, ram-jolt is uniform；3）Negative pressure；4）Burnt in smelting furnace and melt raw scrap material；5）Water solution is poured into ladle, water solution is poured into a mould using ladle the evaporative pattern in sandbox, obtains pump housing idiosome, taken out after shaping to be cooled；6）The mechanical works such as mechanical hole milling, polishing are carried out to the pump housing idiosome after shaping.Using the technical program, the pump housing casting technique overcome using casting technique of the prior art cast out come its hardness of the pump housing and poor abrasion resistance the problem of, so as to improve the hardness and abrasion resistance of the pump housing, and its inherent quality is also guaranteed, and extends the service life of the pump housing.

Description

A kind of casting technique of the pump housing
Technical field
The present invention relates to a kind of casting technique of the pump housing, technical field is manufactured applied to electric machine casing.
Background technology
Pump is a kind of machinery for conveying liquid or being pressurized liquid, and it is by the mechanical energy of prime mover or other external energies Liquid is transmitted, increases liquid energy.When casting the pump housing of pump using casting technique of the prior art, cast out what is come Pump body cast inherent quality is generally poor, and hardness and abrasion resistance can not often meet the application environment demand of pump, thus limit Manufacture of the pump housing in casting field is made.Therefore, we design a kind of casting technique of the pump housing.
The content of the invention
To solve the defect of prior art, the invention discloses a kind of casting technique of the pump housing.
The invention discloses a kind of casting technique of the pump housing, the casting technique of the pump housing is comprised the following steps that：
1）Evaporative pattern is made, producing design drawing according to the pump housing makes evaporative pattern, 60-70 parts that evaporative pattern is made up of parts by weight Epoxy resin, 45-50 part phenolic resin, 6-10 parts of carragheens, 2-3 parts of zinc stearate extrusion formings；
2）Evaporative pattern is packed into sandbox, using natural silica Sand filling in sandbox, the sandbox after filling is placed on shake table On, ram-jolt is uniform；
3）Negative pressure, by the air in mold cavity under negative pressure pump air-extraction function, range of negative pressure 0.05-0.07Mpa discharge sand Air in case；
4）Burnt in smelting furnace and melt raw scrap material, burning melts temperature at 1400-1600 DEG C, adds C：4-8%, Si：2-4%, Mo：0.5- 1.5%, Cu：1-3%, Ni：0.5-1.2%, Cr：0.5-1.3%, Mn：0.5-0.88%, Ni：0.4-0.9%, Sn：0.03-0.05%, Mg：0.03-0.05%, rare earth element：0.1-0.4%, Fe：65-75% mixing burning is melted, and obtains water solution；
5）Water solution is poured into ladle, water solution is poured into a mould using ladle the evaporative pattern in sandbox, obtains the pump housing Idiosome, takes out after shaping to be cooled；
6）The mechanical works such as mechanical hole milling, polishing are carried out to the pump housing idiosome after shaping.
The beneficial effects of the invention are as follows：The pump housing casting technique overcomes to be cast out using casting technique of the prior art The problem of its hardness of the pump housing and poor abrasion resistance for coming, so that the hardness and abrasion resistance of the pump housing are improved, and its inherent quality Also it is guaranteed, extends the service life of the pump housing.
Embodiment
The invention discloses a kind of casting technique of the pump housing, the casting technique of the pump housing is comprised the following steps that：

2）Evaporative pattern is packed into sandbox, using natural silica Sand filling in sandbox, the sandbox after filling is placed on shake table On, ram-jolt is uniform；
3）Negative pressure, by the air in mold cavity under negative pressure pump air-extraction function, range of negative pressure 0.05-0.07Mpa discharge sand Air in case；
4）Burnt in smelting furnace and melt raw scrap material, burning melts temperature at 1400-1600 DEG C, adds C：4-8%, Si：2-4%, Mo：0.5- 1.5%, Cu：1-3%, Ni：0.5-1.2%, Cr：0.5-1.3%, Mn：0.5-0.88%, Ni：0.4-0.9%, Sn：0.03-0.05%, Mg：0.03-0.05%, rare earth element：0.1-0.4%, Fe：65-75% mixing burning is melted, and obtains water solution；
5）Water solution is poured into ladle, water solution is poured into a mould using ladle the evaporative pattern in sandbox, obtains the pump housing Idiosome, takes out after shaping to be cooled；
6）The mechanical works such as mechanical hole milling, polishing are carried out to the pump housing idiosome after shaping.
Finally it should be noted that：Above example only not limits technology described in the invention to illustrate the present invention Scheme；Therefore, although this specification with reference to each above-mentioned embodiment to present invention has been detailed description, this Field it is to be appreciated by one skilled in the art that still can be modified to the present invention or equivalent substitution；And all do not depart from this The technical scheme of the spirit and scope of invention and its improvement, it all should cover in scope of the presently claimed invention.
