Abstract
A novel plunger type supercharging device comprises a valve body, wherein a low-pressure oil supply opening, a high-pressure oil port and a center axial hole are arranged in the valve body, a first one-way valve and a second one-way valve are arranged on the low-pressure oil supply opening and the high-pressure oil port, a plunger rod is arranged in the center axial hole of the valve body, and a guide sleeve, an adjusting gasket and a pressing nut are sequentially sleeved on the plunger rod from inside to outside. The pressing nut abuts against the rear end face of the adjusting gasket and is in threaded fit with the valve body. A plunger cylinder and the valve body are combined as a whole, so the novel plunger type supercharging device is simple in structure, convenient to machine, not prone to deformation, capable of effectively preventing the sticking phenomenon from occurring, and long in service life.
Description
Technical field
The utility model belongs to the ultrahigh-pressure hydraulic equipment technical field, particularly a kind of novel plunger-type supercharging device.
Background technique
at present, the radial plunger pump pressure structure that uses in hydraulic system is mainly plunger coupled parts, be that plunger and plunger case form through abrasive machining, be processed with screw thread on plunger case, be connected with valve body by screw thread, its working principle is: the low pressure hydraulic fluid port passes into low pressure oil all the time, low pressure oil is pushed plunger to left end by low pressure check valve, and the plunger left end is connected with the eccentric shaft of pump case inside, eccentric shaft rotates a circle and pushes plunger to right-hand member, fluid in plunger case is pressed in valve body at this moment, and the pressure of low pressure check valve upper end is greater than the pressure of low pressure hydraulic fluid port, so low pressure check valve is closed, fluid flows into the high pressure hydraulic fluid port by the high pressure one-way valve, and then the fluid of low pressure hydraulic fluid port is pushed plunger to left end again, then ceaselessly repeats above-mentioned motion, until the pressure of high pressure hydraulic fluid port is more and more higher.This plunger coupled parts is very high to processing request, difficulty of processing is large, its bedding-in gap is also very little, because of the plunger case right-hand member with valve body for being threaded, because plunger case after screw thread is tightened, can produce certain pretightening force, this pretightening force can cause the plunger case slight deformation, over the bedding-in gap, will cause plunger and plunger case stuck when amount of deformation; Simultaneously, after the gap experience wear of plunger and plunger case became greatly, the pressure of pump just rose not get on, and this plunger and plunger case will be scrapped.In addition, plunger and plunger case gap are very little, in case there is impurity in fluid, also are easy to cause plunger and plunger case stuck.
The model utility content
The utility model provides a kind of simple in structure, novel plunger-type supercharging device of being convenient to process, be difficult for stuck and long service life.
For achieving the above object, the technical solution of the utility model is: a kind of novel plunger-type supercharging device, comprise valve body, valve body is provided with low pressure oil supply mouth, high pressure hydraulic fluid port and central axial bore, low pressure oil supply mouth and high pressure hydraulic fluid port place are provided with respectively the first one-way valve and the second one-way valve, be provided with plunger rod in the central axial bore of described valve body, from inside to outside be arranged with successively guide sleeve on plunger rod, adjust pad and gland nut, the gland nut top is pressed in to be adjusted on the pad ear end face, and gland nut coordinates with valve body screw thread.
Be arranged with V-shaped seal ring on described plunger rod, V-shaped seal ring is between guide sleeve and adjustment pad.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises valve body, valve body is provided with the low pressure oil supply mouth, high pressure hydraulic fluid port and central axial bore, low pressure oil supply mouth and high pressure hydraulic fluid port place are provided with respectively the first one-way valve and the second one-way valve, be provided with plunger rod in the central axial bore of described valve body, from inside to outside be arranged with successively guide sleeve on plunger rod, adjust pad and gland nut, the gland nut top is pressed in to be adjusted on the pad ear end face, gland nut coordinates with valve body screw thread, this structure is integrated plunger case and valve body, it is simple in structure, be convenient to processing, not yielding, can effectively prevent stuck phenomenon, not easy to wear, long service life.
2, be arranged with V-shaped seal ring on plunger rod, V-shaped seal ring is between guide sleeve and adjustment pad, the good seal performance of V-shaped seal ring, high pressure resistant changes the adjustment pad to the application of force size of V-shaped seal ring by rotatably compressing nut, can adapt to different working pressures; V-shaped seal ring can in time be changed after damaging, and is easy and simple to handle, high working efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Novel plunger-type supercharging device as shown in Figure 1, it comprises valve body 1, is provided with low pressure oil supply mouth 2, high pressure hydraulic fluid port 3 and central axial bore 4 on valve body 1, low pressure oil supply mouth 2 and high pressure hydraulic fluid port 3 places are provided with respectively the first one-way valve 10 and the second one-way valve 11.Be provided with plunger rod 5 in the central axial bore 4 of valve body 1, from inside to outside be arranged with successively guide sleeve 7, V-shaped seal ring 9 on plunger rod 5, adjust pad 8 and gland nut 6, gland nut 6 tops are pressed in to be adjusted on pad 8 ear end faces, adjustment pad 8 tops are pressed on V-shaped seal ring 9, gland nut 6 and valve body 1 screw-thread fit.The good seal performance of V-shaped seal ring 9, high pressure resistant changes by rotatably compressing nut 6 application of force size of adjusting 8 pairs of V-shaped seal rings 9 of pad, can adapt to different working pressures; After V-shaped seal ring 9 damages, can in time change, easy and simple to handle, high working efficiency.
In the present embodiment, guide sleeve 7 is copper sheathing, and plunger rod 5 right-hand members coordinate with copper guide sleeve 7, and guide sleeve 7 can prevent that stuck phenomenon from appearring in plunger rod 5, and guide sleeve 7 be subject to high pressure after sealability also can become better.
