Supercharger without power system

Abstract

The invention discloses a supercharger without a power system. The middle part of the inner cavity of the oil cylinder is threadedly connected with an end cover of the booster chamber, one end of the oil cylinder is threadedly connected with the nitrogen cylinder, and the piston rod of the nitrogen cylinder piston cooperates with the oil cylinder in clearance; the other part of the oil cylinder One end is threadedly connected with an oil cylinder end cover and sealed. The invention is safe and reliable, has a large pressurization range and low manufacturing cost; it does not need an additional external power source, and the pressure in the pressurization process is stable, and the oil pressure of the pressurization chamber can be compensated by the change of the stroke of the nitrogen cylinder piston rod without leakage. , the hydraulic system can be boosted after the hydraulic source is disconnected, and it can also act as an accumulator. The boosting effect is excellent, saving huge energy and greatly reducing costs; especially in flexible production lines, robots and equipment In the coordinated automatic production process, the circuit pressurization and pressure maintenance of the engineering series hydraulic system have more perfect performance, which can replace the high-pressure pump station by pressurization, reduce labor, improve productivity, and ensure product quality.

Description

technical field [0001] The invention relates to the technical field of superchargers, in particular to a supercharger without power system. Background technique [0002] With the continuous advancement of science and technology, the requirements for superchargers in the industrial field are getting higher and higher, which not only requires the supercharger to meet various needs of the mechanical structure, but also requires the miniaturization and high performance of the supercharger. The supercharger in the prior art adjusts the system supercharging by adjusting the spring force. When the system is depressurized, the pressure of the booster system drops, and it cannot maintain the pressure and act as an accumulator. A check valve needs to be installed at the pressurized outlet, and the check valve needs to be dismantled when returning oil, the structure is complex, and the process is cumbersome. The supercharger needs to continuously replenish power during the entire sup...
