Embodiment Construction

[0018] like figure 1 As shown, a single-system single-outlet hydraulic system of the present invention includes a fuel tank 1, a first high-pressure oil pipe 10, and a supporting hydraulic cylinder 17. The inlet of the first high-pressure oil pipe 10 extends into the fuel tank 1. A hydraulic pump 5 driven by a motor 4, a one-way valve 11, an accumulator 14 with a pressure relay 13, a first electromagnetic reversing valve 15, a second electromagnetic reversing valve 16, and a supporting hydraulic cylinder are arranged in sequence along the direction of oil flow. 17.

[0019] The first high-pressure oil pipe 10 is provided with an oil suction filter 3 and a pipeline fine oil filter 8, the oil suction filter 3 is located between the fuel tank 1 and the hydraulic pump 5, and the pipeline fine oil filter 8 is located between the hydraulic pump 5 and the unit between valve 11.

[0020] The first high-pressure oil pipe 10 is provided with a relief valve 7 located between the hydrau...

Abstract

The invention discloses a single-system single-outlet hydraulic system. The single-system single-outlet hydraulic system comprises an oil tank, a first high pressure oil pipe and a supporting hydraulic cylinder; an inlet of the first high pressure oil pipe extends into the oil tank; a hydraulic pump driven by a motor, an one-way valve, an energy storing device with a pressure relay, a first solenoid directional valve, a second solenoid directional valve and the supporting hydraulic cylinder are sequentially arranged on the first high pressure oil pipe in the oil flowing direction. The single-system single-outlet hydraulic system under normal running has the characteristics of being long in pressure maintaining time, free of pressure leaking, low in energy consumption, fast to release pressure, safe and reliable; the braking power or supporting power can be provided to a brake; in addition, the electricity energy consumption can be reduced; an integrated oil circuit is small in size, high in practical and easy to be popularized and used.

Description

technical field [0001] The invention belongs to the technical field of hydraulic pressure, and in particular relates to a hydraulic system with single system and single outlet. Background technique [0002] With the call for energy saving and consumption reduction in corresponding countries, various methods have been adopted in the braking power source of the brake to reduce the power consumption, especially the electrohydraulic propeller used in the normally closed brake. Work wastes a lot of power consumption, and some adopt hydraulic methods, electromagnetic methods or electromagnetic hydraulic methods, etc., but all have the defects of complex structure, short pressure holding time, high energy consumption, and slow pressure relief. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a single-system single-outlet hydraulic pressure pump with integrated oil circuit, small volume, simple structure, accumu...
