Abstract
The utility model discloses a fluoroplastic alloy self sucking pump with a novel structure. The fluoroplastic alloy self sucking pump with the novel structure comprises a pump body, a rear cover, an impeller and a pump shaft used for driving the impeller to rotate. The pump body is composed of a water sucking chamber, a liquid storing chamber and a gas-liquid separation chamber, the front end of the pump body is further connected with a front cover, and the pump body and the front cover are of round structures and connected through round equal part sealing pressing bolts. An outlet in the upper end of the pump body is further provided with a liquid adding hole, a liquid discharging hole is arranged in the bottom of the front cover, and a flow passing component of the pump, the front cover and an outlet connecting flange are all fluoroplastic linings, and combining positions with fluoroplastic are all provided with dovetail grooves and reinforcing holes. According to the fluoroplastic alloy self sucking pump with the novel structure, the problems that casting of the pump body is difficult, machining technology is complicated, lining layers are prone to come off and corrosion resisting performance is poor are solved; the liquid adding hole is added in a liquid outlet position of the pump body, the liquid discharging hole is added in a front cover position, and therefore speed and convenience of liquid adding and liquid discharging are ensured.
Description
Technical field
The utility model relates to a kind of pump, especially relates to a kind of new structure fluoroplastic alloy self-suction pump.
Background technique
Fluoroplastic alloy self-suction pump is a kind of outer mixing centrifugal self-priming pump, can be overall plastic structure, also can be metal shell inner lining fluoroplastics structure.Inside bearing strip, its mechanical strength is higher, and decay resistance is strong, and manufacture cost is lower, mostly is applied to the industries such as petrochemical industry, smelting, papermaking, medicine, food processing.At present, its pump housing of pump of the same type has whole manufacturing type, split manufacturing type, various structural type.
Whole manufacturing type, general pump body adopts line with rubber to carry out preservative treatment, and corrosion resistance is relatively poor, and application area is narrow, and inner liner rubber and steel body be easy to shell also, thereby affects the use of self-priming pump.Split manufacturing type, in general, local part designs simplification, but complicated integral structure, the patent No. of announcing such as State Intellectual Property Office: a kind of steel lining fluoroplastic alloy self-suction pump of 200710135169.8, its number of spare parts is many, the pump housing is by three part manufacturings, and it is many to open molding jig, and manufacture cost is relative also higher, increase user's user cost, be unfavorable for promoting the use of of the type pump.In addition, because its number of spare parts is many, the bolt tie point is also many, and seal leakage point increases, and for anti-corrosive pump, seal leakage point increases, and will increase the potential safety hazard that pump uses.
The model utility content
The purpose of this utility model is to provide a kind of Novel fluoroplastic alloy self-suction, a series of defectives such as can solve effectively that pump housing casting is difficult, processing technology is complicated, backing layer easy to shell, decay resistance are relatively poor.
The utility model is achieved through the following technical solutions:
A kind of new structure fluoroplastic alloy self-suction pump, include the pump housing, bonnet, the pump shaft of impeller and impeller rotation, the described pump housing is by suction chamber, liquid storage room and the three of gas-liquid separation chamber consist of, pump housing front end also is connected with protecgulum, the joint of protecgulum and the pump housing is provided with the protecgulum seal ring, pump housing upper end is connected with the outlet adpting flange, be fixedly installed a dividing plate in the pump housing, the bottom of described dividing plate is fixedly connected with the liquid storage room outer wall, it is indoor that its top extends to gas-liquid separation, the described pump housing is the integral type structure of global formation, the described pump housing and protecgulum are round structure, the pump housing and protecgulum are connected by circular equal portions sealing hold-down bolt, protecgulum be connected by the tight bolt of a symmetrical sealing pressing between pump housing inserts is U-shaped, described pump housing inserts is monolithic construction, the upper end outlet of the described pump housing also is provided with liquid filling hole, described protecgulum bottom is provided with taphole, and described pump flow passage components and protecgulum and outlet adpting flange are fluoroplastics lining, with the fluoroplastic junction dovetail groove and reinforced hole are arranged all.
The ectosome of described pump structure parts is the HT200 material.
Described pump housing gas-liquid separation chamber uses the external outer pipe of pump in the part.
The beneficial effects of the utility model are:
1, the utility model adopts whole manufacturing forming process, designs simplification, and the pump flow passage components are fluoroplastics lining, metal shell and plastic junction car dovetail groove, brill reinforced hole, lining is moulded tightr, fine and close, is difficult for shelling, and the decay resistance using scope is wide, rate of fault obviously reduces, and reduces customer using cost.
2, the utility model pump housing inserts is designed to integrated type, improves bulk strength, so that reinforced hole is bored at the not yielding lining place of moulding when the mould compression moulding, so that lining is moulded is tightr, fine and close, is difficult for the disengaging inserts.
3, the utility model protecgulum with increased by two place's bolts between pump housing inserts is U-shaped and be connected, make sealing surface stressed evenly, multi-sealed, it is best that the sealing between the pump housing and the protecgulum reaches.
4, the utility model pump housing outlet port is provided with liquid filling hole, only needs once to add to draw liquid, before the restarting, need not add and draw liquid, and moment fluid, without secondary self-priming time, energy saving.
5, the utility model protecgulum bottom is provided with tap hole, is convenient to the cleaning of pump body liquid, is convenient to maintenance.
