Description
Technical field
The utility model belongs to reciprocating pump technical field, especially relates to a kind of high pressure reciprocating pump fluid end structure.
Background technique
Reciprocating pump a kind ofly relies on the to-and-fro motion in pumping cylinder of piston, plunger or barrier film to make swept volume in cylinder alternately increase and reduce the positive displacement pump carried liquid or make it supercharging.At present, various high pressure reciprocating pump is all applied at high pressure water jet auxiliary rock coal breakage, underground hydraulic pressure pillar feed flow, Cleaning by High Pressure Water Jet, metallurgical de-scaling, powder metallurgy, shipping cleaning scrubbing, foundation engineering, Liquid transfer, engineering driving and various sebific duct, metal tube, oil drilling wellhead equipment pressure testing pump.In reciprocating pump the working life of fluid end assembly and power end assembly be then its application key, the main Problems existing of reciprocating pump hydraulic-end in prior art, one, flow is relatively less than normal, its two be stuffing box structure complexity, not quick detachable.
Summary of the invention
It is simple that problem to be solved in the utility model is to provide a kind of structure, reduces fluid end rate of fault, improve the working condition of stuffing box on fluid end, stable working, can adapt to the high pressure reciprocating pump fluid end structure of large discharge requirement.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of high pressure reciprocating pump fluid end structure, comprise pump head, valve group, stuffing box, described valve group is arranged at pump head inside, described pump head is connected with bracket, described stuffing box is fixed on pump head by bracket, described stuffing box, bracket is connected by socket head screw with pump head, described pump head and stuffing box connecting part are provided with the first O-ring seals, described stuffing box comprises stuffing box, plunger, stuffing box spring, spring press-cover, packing seal, sealed pressing sleeve and locking mother, described plunger is arranged at stuffing box inside, near pump head position above and below described stuffing box, be respectively arranged with upper process structure and lower process structure, described stuffing box spring, spring press-cover, packing seal, sealed pressing sleeve and locking mother are set in turn between stuffing box and plunger, the second O-ring seals is provided with between described sealed pressing sleeve and stuffing box, U-shaped seal ring is provided with between sealing gland and plunger.
Described upper process structure is provided with lifting bolt.
Described packing seal adopts flower filler.
Described first O-ring seals and the second O-ring seals all adopt fluorine rubber.
Described U-shaped seal ring adopts nitrile butadiene rubber.
Owing to adopting technique scheme, by the reasonable disposition to stuffing box, make this reciprocating pump flow large, stable working, and this stuffing box is connected with pump head with bracket by socket head screw, structure is simple, easy dismounting and change, avoid dismantling pump head, convenient for maintaining, reduce fluid end rate of fault.
The beneficial effects of the utility model are: have structure simple, reduce fluid end rate of fault, improve the working condition of stuffing box on fluid end, stable working, can adapt to the advantage of large discharge requirement.
