Abstract
The invention discloses a lining plastic corrosion resisting fan. An outer shell of the lining plastic corrosion resisting fan is composed of a pump cover and a volute. The inner walls of metal layers of the pump cover and the volute are coated with plastic layers. The metal layers are cast steel layers or steel plate layers, and the plastic layers are coatings in which molding powder of a powder body is attached to the surfaces of the metal layers after being melted. The lining plastic corrosion resisting fan is low in manufacturing cost, short in manufacturing period and simple in technology, and local damage of the inner lining plastic layer can be quickly repaired. The plastic layers and the metal layers are combined integrally in a hot melting mode, binding force is strong, synchronous expanding and contracting can be achieved, delaminating is not easy, impact resistance strength is high, surface smooth friction coefficient is small, scaling is not easy, manufacturing and processing are convenient, and large devices with any structures and shapes can be manufactured.
Description
Technical field
The present invention relates to the blower fan field, especially a kind of lining is moulded corrosion resistant fan.
Background technique
The many employings of existing corrosion resistant fan are ceramic-lined, and shell adopts cast iron to carry out armouring, and the shortcoming of this blower fan is that cost is high, and the manufacturing cycle is long, complex process; Pottery is brittle material, and shortcoming is to be subjected to mechanical collision easily broken, and shock heating quenching then can burst, and rear unrepairable breaks; Make and processing difficulties, can not make large equipment, general ceramic products diameter is no more than 1.2 meters, highly is no more than 1.5 meters.And the hardness of pottery is very high, can only process with abrasion wheel grinding, and difficulty of processing is large, and cost is high, and environment is had pollution.
Summary of the invention
The applicant is ceramic-lined for the many employings of above-mentioned corrosion resistant fan, has the shortcomings such as cost is high, manufacturing cycle length, complex process, provides a kind of lining rational in infrastructure to mould corrosion resistant fan, thereby effectively reduces cost, and expanded the application area of blower fan.
The technical solution adopted in the present invention is as follows:
A kind of lining is moulded corrosion resistant fan, and its shell is comprised of pump cover and volute, the metal layer internal face coating plastic layer of described pump cover and volute.
It is further characterized in that: described metal layer is cast steel layer or steel plate layer.
Described plastic layer is the coating that is attached to layer on surface of metal after the molding powder melting of powder.
Beneficial effect of the present invention is as follows:
Low cost of manufacture of the present invention, the manufacturing cycle is short, and technique is simple, and the local damage of the lining plastic bed of material can be repaired fast.Plastics and metal layer hot melt are combined as a whole, and combination force is strong, and dilation is difficult for delamination synchronously, and impact strength is high, and the smooth surface friction ractor is little, and is less scaling; Manufacturing and easy to process can be made any structure shape large equipment.
Description of drawings
Fig. 1 is the sectional view of pump cover of the present invention.
Fig. 2 is the sectional view of volute of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Such as Fig. 1, shown in Figure 2, the shell that lining of the present invention is moulded corrosion resistant fan is moulded volute 5 by plastic lined pump lid 3 shown in Figure 1 with lining and is formed, wherein the material of pump cover 3 is cast steel layer 1, volute 5 adopts 4 welding of A3 steel plate or casting to form, at the internal face coating plastic layer 2 of pump cover 3 with volute 5, specifically, metal shell is warming up to 200 ℃, utilize artificial molding powder (PO with powder, PE, PP etc., for example the trade mark is LL0209AA, and Sai Ke company in Shanghai produces) evenly spread upon the metal material internal face, at high temperature molding powder generation melting also is attached to the metal layer internal face, more than thickness 5 ㎜ of plastic layer, namely become one after the cooling.
Above description is explanation of the invention, is not that limited range of the present invention is referring to claim, in the situation that without prejudice to spirit of the present invention, the present invention can do any type of modification to the restriction of invention.
