DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figure 1 shown, a technical solution provided by the present utility model is as follows:

[0021] A high-pressure oil supply system includes a lubricating oil pressure tank 2. One end of the lubricating oil pressure tank 2 is provided with a pneumatic pressure reducing valve A 1, and the other end of the lubricating oil pressure tank 2 is provided with a pneumatic pressure reducing valve B 12. The pneumatic pressure reducing valve A 1 is connected to the pneumatic pressure reducing valve B 12; a booster cylinder 8, one end of the booster cylinder 8 is connected to the lubricating oil pressure tank 2, and the adjacent side of the booster cylinder 8 is connected to the pneumatic directional control valve 11 through two pipelines, and the other end of the pneumatic directional control valve 11 is connected to the pneumatic pressure reducing valve B 12; a lubricating oil valve 3, the oil inlet end of the lubricating oil valve 3 is connected to the oil outlet end of the booster cylinder 8; a check valve B 6 is further connected between the lubricating oil pressure tank 2 and the booster cylinder 8; a check valve A 5 is also connected between the booster cylinder 8 and the lubricating oil valve 3; an accumulator 4 is further provided between the check valve A 5 and the lubricating oil valve 3; magnetic switches A 9 and B 10 are respectively arranged at the upper and lower ends inside the booster cylinder 8; a booster cylinder boosting chamber 7 is arranged at the upper end inside the booster cylinder 8;

[0022] In this embodiment, different piston area ratios of the booster cylinder can achieve different ratios of boosting effects. The gas circuit is configured with two pneumatic pressure reducing valves, namely pneumatic pressure reducing valve A1 and pneumatic pressure reducing valve B12. The oil circuit is configured with an accumulator 4, which can effectively reduce the pressure fluctuation generated by the commutation of the booster cylinder. The pressure tank provides pneumatic back pressure so that the lubricating oil in the pressure tank can be quickly replenished into the boosting chamber 7 of the booster cylinder. The one-way valve A5 and the one-way valve B6 can ensure that the lubricating oil will not flow back and relieve pressure when the boosting piston extends and retracts.

[0023] Working principle: The pneumatic directional control valve 11 is energized for commutation -> the cylinder 8 of the booster cylinder returns -> the magnetic switch B10 is lit -> the lubricating oil in the lubricating oil pressure tank 2 quickly enters the boosting chamber 7 of the booster cylinder -> the pneumatic directional control valve 11 is de-energized -> the piston of the cylinder 8 of the booster cylinder presses upwards -> a part of the high-pressure oil is output and a part is reserved -> as the high-pressure oil is slowly consumed, the magnetic switch A9 is lit -> the pneumatic directional control valve 11 is energized for commutation again.

[0024] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
