Abstract
The utility model discloses a high-performance anticorrosion metering pump, which comprises a motor, a transmission case body, a thermal plastic pump body and a front cover. The motor is connected with the transmission case body. One end of the thermal plastic pump body is connected with the transmission case body while the other end is connected with the front cover. A diaphragm cell is formed inside one thermal plastic pump body end which is adjacent to the front cover. A diaphragm is equipped inside the diaphragm cell. An eccentric device and a connecting rod are equipped inside the transmission case body. A connecting rod channel is formed inside the thermal plastic pump body. The connecting rod traverses the connecting rod channel and is connected with the diaphragm. By adopting the thermal plastic pump body, the metering pump can effectively prevent the pump body from being corroded by the chemical agents. The metering pump can be repeatedly used for a plurality of times. Furthermore, the adopted thermal plastic pump body which can be formed by one-time injection molding has a simple producing technology. The raw material cost and the processing cost are both relatively low. Therefore, the producing cost is effectively reduced.

Background technique
Metering pump is a kind ofly can satisfy various strict process requirementss of process, flow can be in the 0-100% scope step-less adjustment, be used for carrying a kind of special displacement pump of liquid.Metering pump also claims metering pump or dosing pump.Metering pump belongs to reciprocating volumetric pump, is used for accurate measurement, and require the steady state accuracy of metering pump to be no more than usually ± 1%.Along with modernization industry continuous development towards automation mechanized operation, this situation of far distance automatic controlling, the matching performance of metering pump is strong, adapt to medium (liquid) widely advantage particularly seem outstanding.
The Environmental Conditions majority that metering pump is commonly used is a caustic chemical environments, and traditional metering pump pump housing all is a metal body at present, be easy to react with chemicals, corroded by chemicals, and metering pump employing metallic material, weight is heavier, can not second use, also do not meet the environmental protection and energy saving requirement, and can prevent metal (as titanium) to chemical corrosion for some, its cost is often again than higher.Have metering pump to adopt the metallic material can not be one-body molded again, and therefore processing charges also than higher.
The model utility content
At above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model provides a kind of good corrosion resistance, the metering pump of low cost of manufacture.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of high-performance corrosion protection metering pump, comprise motor, transmission case body, the thermoplastic materials pump housing and protecgulum, described motor is connected with described transmission case body, one end of the described thermoplastic materials pump housing is connected with described transmission case body, the other end of the described thermoplastic materials pump housing is connected with described protecgulum, the described thermoplastic materials pump housing is near forming a diaphram tank in the end of described protecgulum, be provided with a barrier film in the described diaphram tank, be provided with eccentric and connecting rod in the described transmission case body, form a connecting rod passage in the described thermoplastic materials pump housing, described connecting rod passes described connecting rod passage and is connected with described barrier film.
Preferably, be provided with wear-resisting copper sheathing in the described connecting rod passage.
Preferably, the material of the described thermoplastic materials pump housing is teflon, poly-trifluoro-ethylene, polyfluorinated ethylene, polypropylene, polyphenylene sulfide, PVC, polymeric liquid crystal copolymer (LCP) or ABS material.
Preferably, be provided with oil sealing in the described connecting rod passage.
Preferably, an end of the close described transmission case body of the described thermoplastic materials pump housing is provided with the flange of outside protrusion, and described flange covers described transmission case body.
Technique scheme has following beneficial effect: the pump housing of this metering pump adopts the thermoplastic materials pump housing, can effectively prevent the corrosion of chemical agent to the pump housing, the metering pump pump housing can be repeatedly used, but and employing thermoplastic materials pump housing single injection-molded, production technology is simple, be that expense of raw materials or processing charges are all lower, effectively reduced cost of production.
