Abstract

The invention provides a hydraulic system for oil cylinder control, and belongs to the technical field of oil cylinders. The hydraulic system comprises an oil tank, a hydraulic pump, an oil cylinder assembly and a control assembly. The oil cylinder assembly comprises a first three-position four-way reversing valve, a first hydraulic control one-way valve, a second hydraulic control one-way valve and an oil cylinder. The control assembly comprises a first reversing valve, a second reversing valve, an energy accumulator and an overflow valve. A first oil port of the first reversing valve communicates with an oil outlet of the hydraulic pump; a second oil port of the first reversing valve communicates with the energy accumulator; an oil inlet of the overflow valve respectively communicate with an oil outlet of the hydraulic pump and a first control oil port of the overflow valve, an oil outlet of the overflow valve communicates with an oil return port of the oil tank, a second control oilport of the overflow valve communicates with a first oil port of the second reversing valve, and a second oil port of the second reversing valve communicates with the energy accumulator. The hydraulic system provided by the invention can still keep normal work of the oil cylinder under emergency conditions.

Description

technical field [0001] The disclosure belongs to the technical field of oil cylinders, and in particular relates to a hydraulic system for oil cylinder control. Background technique [0002] In the hydraulic system in the marine field, the control of various output devices, such as oil cylinders and motors, can be realized through hydraulic oil. [0003] In the related art, the hydraulic system controls hydraulic oil to enter the rod chamber or the rodless chamber of the oil cylinder, so as to realize the control of the expansion and contraction of the piston rod of the oil cylinder, and then convert the hydraulic energy into the mechanical energy of the piston rod. [0004] Ships sailing at sea will encounter emergency situations such as harsh natural environments, which will increase the load on the oil tank. However, the pressure of the above-mentioned hydraulic system is constant, so that the load output by the oil cylinder is constant, which will make the load of the o...
