Abstract
The utility model discloses a lining plastic corrosion-resistant fan. A casing of the lining plastic corrosion-resistant fan consists of a pump cover and a volute, wherein plastic layers are coated on the inner wall surfaces of metal layers of the pump cover and the volute; the metal layers are cast steel layers or steel plate layers; and the plastic layers are coatings formed by fusing molding powder of a power body and attaching the fused molding powder to the surfaces of the metal layers. The lining plastic corrosion-resistant fan disclosed by the utility model is low in manufacturing cost, short in manufacturing period and simple in process; and locally-damaged lining plastic layer can be quickly recovered. The plastic and the metal layer are combined together by hot melting; the lining plastic corrosion-resistant fan can synchronously expand and shrink and can be manufactured into large equipment with any structural shape; and the lining plastic corrosion-resistant fan has the advantages of strong binding force, low possibility of delaminating, high impact resistant strength, smooth surface, small friction coefficient, low possibility scaling and convenience in manufacturing and processing.
Description
Technical field
The utility model relates to the blower fan field, and 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 a brittle material, and shortcoming is to receive mechanical collision broken easily, and shock heating quenching then can burst, and can not repair after breaking; 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 big, and cost is high, and environment is had pollution.
The model utility content
The applicant is ceramic-lined to the many employings of above-mentioned corrosion resistant fan, has shortcomings such as cost height, manufacturing cycle length, complex process, provides a kind of lining rational in infrastructure to mould corrosion resistant fan, thereby has effectively reduced cost, and expanded the application area of blower fan.
The technological scheme that the utility model adopted is following:
A kind of lining is moulded corrosion resistant fan, and its shell is made up of pump cover and volute, the metal layer internal face coating plastic layer of said pump cover and volute.
It is further characterized in that: said metal layer is cast steel layer or steel plate layer.
Said plastic layer is attached to the coating of layer on surface of metal after the molding powder fusion of powder.
The beneficial effect of the utility model is following:
The utility model low cost of manufacture, the manufacturing cycle is short, and technology is simple, and the local damage of plastic lining layer can be repaired fast.Plastics and metal layer hot melt are combined as a whole, and combination force is strong, and the contraction of can expanding synchronously is difficult for delamination, 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 the pump cover of the utility model.
Fig. 2 is the sectional view of the volute of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described.
Like Fig. 1, shown in Figure 2, the shell that the described lining of the utility model is moulded corrosion resistant fan is moulded volute 5 by plastic lined pump lid 3 shown in Figure 1 with lining and is formed, and wherein the material of pump cover 3 is a 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 ℃, and the artificial molding powder with powder of utilization (PO, PE, PP etc., for example the trade mark is LL0209AA; The production of Shanghai Sai Ke company) evenly spread upon the metal material internal face; The fusion of molding powder generation at high temperature and attached to the metal layer internal face more than thickness 5 ㎜ of plastic layer, promptly becomes one after the cooling.
More than describing is the explanation to the utility model, is not the qualification to model utility, and the utility model institute restricted portion is referring to claim, and under the situation of the utility model spirit, the utility model can be done any type of modification.
Claims (3)
