The utility model is exactly for the problems referred to above, provides a kind of reciprocating pump that a kind of efficiency is high, stable.
For achieving the above object, the utility model adopts following technological scheme, a kind of reciprocating pump, comprise fluid end and power end, it is characterized in that: fluid end comprises cylinder body, cylinder body top is provided with liquid feed valve, inferior part of the cylinder block is provided with liquid valve, cylinder body side is provided with guide pipe, plunger is provided with in guide pipe, between plunger and guide pipe, be provided with stuffing box packing chamber, stuffing box packing is provided with stuffing box packing in chamber, is provided with the feeding port communicated with stuffing box packing chamber above guide pipe, feeding port is provided with buckle closure, and in guide pipe end, stuffing box packing chamber opening is provided with capping; Opposite side relative with guide pipe on cylinder body is provided with capping flange, and capping flange is provided with flange nut; Described power end comprises housing, and housing comprises actuator chamber and drive link passage; Be provided with the bent axle be connected with motor shaft in actuator chamber, bent axle is by connecting rod connection for transmission bar, and drive link end is provided with crosshead, and described connecting rod is connected in described crosshead; Between actuator chamber and drive link passage, be provided with sealing cut off, sealing cuts off middle part and is provided with import and export, described drive link is placed in described import and export, sealed pressing sleeve is provided with between the import and export that drive link and sealing cut off, be provided with water pushing plate in drive link front end, the front end of drive link is connected with plunger one end not in cylinder body.
As a kind of preferred version of the present utility model, described shell is stainless steel casing; Stainless steel casing is firm in structure, long service life.
The utility model beneficial effect.
The utility model efficiency is high, and in using process, pressure change affects flow hardly, thus can provide constant flow.And there is suction capacity, can conveying liquid, gas mixture, particular design can also slurry conveyed, concrete etc.; Complete function.In addition, reciprocating pump can be used for providing high pressure liquid source, and the high pressure water as hydraulic press supplies, and it and reciprocating pump all can be used as the drilling mud pump of oilfield.
Accompanying drawing explanation
Fig. 1 is the utility model fluid end structure schematic diagram.
Fig. 2 is the utility model power end structural representation.
In figure, 1 be liquid valve, 2 be capping flange, 3 be flange nut, 4 be cylinder body, 5 be liquid feed valve, 6 be buckle closure, 7 be stuffing box packing chamber, 8 be stuffing box packing, 9 be plunger, 10 be actuator chamber, 11 be bent axle, 12 be connecting rod, 13 for sealing cut off, 14 be sealed pressing sleeve, 15 be drive link, 16 be water pushing plate, 17 for drive link passage.
Embodiment
As shown in the figure, a kind of reciprocating pump, comprise fluid end and power end, it is characterized in that: fluid end comprises cylinder body 4, cylinder body 4 top is provided with liquid feed valve 5, cylinder body 4 bottom is provided with liquid valve 1, cylinder body 4 side is provided with guide pipe, plunger 9 is provided with in guide pipe, stuffing box packing chamber 7 is provided with between plunger 9 and guide pipe, stuffing box packing 8 is provided with in stuffing box packing chamber 7, above guide pipe, be provided with the feeding port communicated with stuffing box packing chamber 7, feeding port is provided with buckle closure, and in guide pipe end, stuffing box packing chamber 7 opening is provided with capping; Opposite side relative with guide pipe on cylinder body 4 is provided with capping flange 2, and capping flange 2 is provided with flange nut 3; Described power end comprises housing, and housing comprises actuator chamber 10 and drive link passage 17; Be provided with the bent axle 11 be connected with motor shaft in actuator chamber 10, bent axle 11 is by connecting rod 12 connection for transmission bar 15, and drive link 15 end is provided with crosshead, and described connecting rod 12 is connected in described crosshead; Between actuator chamber 10 and drive link passage 17, be provided with sealing cut off, sealing cuts off middle part and is provided with import and export, described drive link 15 is placed in described import and export, sealed pressing sleeve is provided with between the import and export that drive link 15 and sealing cut off, be provided with water pushing plate 16 in drive link front end, the front end of drive link 15 is connected with plunger 9 one end not in cylinder body 4.
Described shell is stainless steel casing; Stainless steel casing is firm in structure, long service life.
When plunger 9 moves from left to right, the volume of cylinder body 4 inside just increases, and pressure is along with reduction, and when the fluid pressure entered is greater than the pressure in cylinder body 4, liquid, under differential pressure action, is opened liquid feed valve 5 and enters in cylinder body.After turning over 180 degree when bent axle, piston 9 is moved to the left.Because liquid water compressibility is not very large, liquid is compressed by piston 9 immediately and pressure raises rapidly, and cylinder body 4 internal pressure is raised.Until the fluid pressure in cylinder body arrives greatly when enough opening liquid valve 1, liquid is discharged from liquid valve.
