[CN 201721124164.0] Pressure-boosting oil cylinder and ultra-high pressure plate hydraulic press
[CN 201721124164.0] Title of a booster cylinder and ultra-high pressure plate hydraulic press: Application number of a booster cylinder and ultra-high pressure plate hydraulic press: CN 201721124164.0 Applicant: Zhu Mianxue Application Date: 2017-9-4 Patent Type: Utility Model The utility model discloses a booster cylinder and an ultra-high pressure plate hydraulic press including a booster cylinder. The booster cylinder includes a cylinder barrel and a plunger, and the plunger is located in the cylinder barrel and slidably connected with the inner wall of the cylinder; the plunger is provided with a cavity inside, and a booster piston is arranged in the cavity. The booster piston is slidably connected with the inner wall of the plunger. The plunger is also provided with a pump pressure port and a booster oil port. The pump pressure oil port sequentially penetrates the plunger, the isolation sleeve and the booster piston; one end of the booster oil port opens on the outer wall of the upper part of the plunger, and the other end opens to the connection between the upper part of the plunger and the booster piston. In the utility model, through the combination of the plunger and the booster piston, through the secondary pressurization, the booster cylinder forms an ultra-high pressure, without a supercharger, an ultra-high pressure valve group and an ultra-high pressure pipeline, which simplifies the hydraulic system of the hydraulic press, Reduce costs; ban the ultra-high pressure pipeline, improve safety, improve pressing efficiency, and reduce energy consumption.
