Abstract

The invention discloses a pressure boost oil cylinder and an ultrahigh pressure sheet bar hydraulic machine. The pressure boost oil cylinder comprises a cylinder barrel and a plunger, and the plunger is located in the cylinder barrel and connected to the inner wall of the cylinder barrel in a sliding mode; a cavity is formed in the plunger, a pressure boost piston is arranged in the cavity, and the pressure boost piston is connected to the inner wall of the plunger in a sliding mode; a pumping pressure oil mouth and a pressure boost oil mouth which are communicated with each other are further formed in the plunger, and the pumping pressure oil mouth penetrates through the plunger, a distance sleeve and the pressure boost piston in sequence; an opening is formed in the end, located on the outer wall of the upper portion of the plunger, of the pressure boost oil mouth, and the other end of the pressure boost oil mouth is formed in the connection portion between the upper portion of the plunger and the top of the pressure boost piston. According to the pressure boost oil cylinder, the plunger is combined with the pressure boost piston, through secondary pressure boost, the pressure boost oil cylinder forms ultrahigh pressure, a pressurizer is not needed, through an ultrahigh pressure valve group and an ultrahigh pressure pipe, a hydraulic system of the hydraulic machine is simplified, and the cost is lowered; the ultrahigh pressure pipe is removed, the safety is improved, the pressing efficiency is improved, and the energy consumption is lowered.

Description

technical field [0001] The invention relates to a hydraulic device, in particular to a pressurized oil cylinder and an ultra-high pressure plate hydraulic press. Background technique [0002] At present, the oil pressure of pressurized cylinders of hydraulic presses such as plate heat exchangers at home and abroad is mostly ultra-high pressure (50-100MPa), and the oil supply is composed of superchargers, ultra-high pressure valve groups, and ultra-high pressure pipelines. ultra-high pressure oil supply system. This kind of oil supply system is relatively complicated, the fault is not easy to judge, and the efficiency of the reciprocating supercharger is low, which affects the production efficiency. In addition, the quality of ultra-high pressure pipeline installation and manufacturing is crucial to machine safety, especially personal safety. [0003] Therefore, providing a pressurized oil cylinder and an ultra-high pressure plate hydraulic press to solve the above-mentione...
