Problems solved by technology

[0002] In order to prevent the three-dimensional hydraulic cylinder or the vertically moving working parts from sliding down due to their own weight, the current market is mainly to set appropriate hydraulic resistance on the down circuit of the vertical cylinder, but the resistance is not adjustable and not stable enough. It also lacks safety. Once the circuit is out of control due to liquid resistance, the maintenance cost is very high

Embodiment Construction

[0007] Below in conjunction with accompanying drawing, further illustrate the present invention.

[0008] Such as figure 1 The structural representation of the present invention shown, it comprises oil pump 1, overflow valve 2, electromagnetic valve 3, sequence valve 4 and hydraulic cylinder 5, the intermediate place of the output end of described oil pump 1 and the input end of electromagnetic valve 3 is provided with overflow Valve 2, the output end of electromagnetic valve 3 is connected with the input end of sequence valve 4, the output end of sequence valve 4 is connected with one end of hydraulic cylinder 5, and the other end of hydraulic cylinder 5 is connected with electromagnetic valve 3.

[0009] Such as figure 1 As shown, the adjustment pressure of the sequence valve 4 should be slightly greater than the pressure of the mass of the working parts in the stroke of the lower cavity of the hydraulic unit 5. When the self-weight is large, the pressure of the sequence va...

Abstract

The invention discloses a hydraulic system for preventing a hydraulic circuit from being influenced by the dead weight of a part. The hydraulic system comprises an oil pump, an overflow valve, an electromagnetic valve, a sequence valve and a hydraulic cylinder, wherein the overflow valve is arranged between the output end of the oil pump and the input end of the electromagnetic valve; the output end of the electromagnetic valve is connected with the input end of the sequence valve; the output end of the sequence valve is connected with one end of the hydraulic cylinder; and the other end of the hydraulic cylinder is connected with the electromagnetic valve. The system is stable and reliable, and has high adjustability and low maintenance cost.

Description

technical field [0001] The invention relates to a hydraulic system which prevents the balance of a hydraulic circuit from being affected by the self-weight of parts. Background technique [0002] In order to prevent the three-dimensional hydraulic cylinder or the vertically moving working parts from sliding down due to their own weight, the current market is mainly to set appropriate hydraulic resistance on the down circuit of the vertical cylinder, but the resistance is not adjustable and not stable enough. It also lacks safety. Once the circuit is out of control due to liquid resistance, the maintenance cost is very high. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to solve the deficiencies of the prior art, provide a hydraulic system that prevents the balance of the hydraulic circuit from being affected by the self-weight of the parts, and prevent the three-dimensional hydraulic cylinder or vertically moving working parts...
