Problems solved by technology

[0007] The invention patent with the application number 201720584115.9 uses the hydraulic control check valve to release the pressure oil on the other side of the hydraulic control valve when it is reversing. After the booster piston makes corresponding feedback, the control oil circuit is disconnected, the hydraulic control check valve is reset, the spool and booster piston are in an uncertain state, and the commutation is abnormal.

Embodiment 1

[0073] like Figure 12 As shown, the supercharger piston 2 and the booster plunger are connected to form a piston assembly through a half ring 2.4, a circlip 2.5, a valve seat 2.6, and a steel ball 2.7. This structure can ensure that the piston rod has a certain axial direction relative to the piston. Radial floating prevents the piston rod from being stuck in the cavity and affecting normal work.

[0074] The hydraulic control reversing slide valve 4 adopts a slide valve structure, such as Image 6 Shown: it consists of left valve body cover 4.1, valve body 4.2, piston 4.3, right valve body cover 4.4 and oil passages a, b, 4.x, 4.y, p2, t and corresponding seals components and fasteners. The working principle has been briefly described above and will not be repeated here. In the background, it is introduced that the standard hydraulic control reversing valve 3 needs to control the oil ports x and y to supply oil / return oil in the relevant state in order to keep the positio...

Embodiment 2

[0081] The main structure and reversing principle are similar to those of Embodiment 1, except that the spool 4.3 of the liquid-changing control reversing slide valve 4 is slightly different from Embodiment 1. In this embodiment, two radial ring grooves are provided. In Embodiment 1, four radial annular grooves are provided on the valve core of the control component, communicating with p2, t, x, and y respectively. At the working position on the left and right sides of the spool, the corresponding oil circuits are connected: if the y side of the reversing valve is connected to the control oil p, and the x side is connected to T, the spool moves to the left, such as Figure 8 and Figure 9 As shown, at this time, P--B is connected, A--T is connected, the reversing mechanism completes the action switching, the right side function enters the working state, and the supercharger piston assembly moves to the left under the pressure difference between the two ends of the piston, as s...

Abstract

A hydraulic control reciprocating supercharger comprises a hydraulic control reversing sliding valve of a hydraulic control reversing control mechanism, it can be guaranteed that a valve element of a hydraulic control reversing valve of a reciprocating supercharger system is located at a determined position, that is, when a hydraulic control reversing valve control component controls an oil port a to supply oil and b is communicated with an oil tank, the valve element moves to the right side, and at the moment, corresponding oil supply channels are communicated; a right side control oil port y of the hydraulic control reversing valve is communicated with control oil, a left side control oil port x is communicated with an oil tank, a right side machine works, and a piston assembly moves rightwards; uninterrupted supply of a control oil way is achieved, it can be guaranteed that under the stroke, the position of a valve element of the hydraulic control reversing slide valve is fixed, and it is guaranteed that a piston of the reciprocating supercharger moves towards the right side; and when the piston moves to the left limit position, the actions are repeated, it is ensured that the motion direction of the piston of the supercharger is smoothly switched, the piston moves to the right side, and the hydraulic control reciprocating motion of the supercharger is achieved and system pressurization is ensured through reciprocating circulation.

Description

technical field [0001] The invention belongs to the field of hydraulic technology, and relates to a hydraulically controlled reciprocating supercharger, in particular to a hydraulic supercharger with hydraulically controlled automatic reversing using a hydraulically controlled reversing valve. Background technique [0002] Synthetic equipment for synthetic diamond in my country is a six-sided hydraulic press, which uses an ultra-high pressure hydraulic system with an oil pressure of 100MPa. The working process of the hydraulic system mainly includes: emptying the oil cylinder, quickly increasing the pressure to 6MPa, then slowly overpressurizing to about 100MPa and maintaining it, and finally the pressure relief process. [0003] At present, the mainstream overpressure devices are ultra-high pressure oil pumps and reciprocating superchargers. Ultra-high pressure oil pumps can overpressure without restriction within the rated pressure but the flow rate is small. To achieve th...
