Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Such as figure 1 As shown, the present invention connects a primary degassing valve 6 between the hydraulic pump 20 and the actuator 5, and one outlet of the primary degassing valve 6 is connected to the actuator 5 through the hydraulic oil outlet pipeline 4, and the primary degassing valve 6 The other outlet of the gas-oil mixture outlet 7 is connected to the oil distribution tank 14; the hydraulic oil stored in the oil distribution tank 14 flows into the main oil tank 1 after being degassed by the secondary degassing system 8, and the primary degassing valve 6 is connected in series in the hydraulic mechanism ; The secondary degassing system 8 that runs alone is connected in parallel in the hydraulic mechanism.

[0029] Its working principle is: when the hydraulic mechanism is working, the hydraulic oil is driven by the hydraulic pressure 20 t...

Abstract

The invention discloses an energy-saving environmental-friendly noise reduction system applied to a hydraulic mechanism. A primary degassing valve is connected between a hydraulic pump and an execute component; one outlet of the primary degassing valve is connected with the execute component and the other outlet of the primary degassing valve is connected with a branch oil tank; hydraulic oil stored in the branch oil tank flows into a main oil tank after being degassed by a secondary degassing system; the primary degassing valve is connected in series into the hydraulic system; the independently operated secondary degassing system is connected in parallel into the hydraulic mechanism; and the secondary degassing system which is connected in parallel to the hydraulic mechanism is controlled by a hydraulic detection circuit and works intermittently, the content of gas in the hydraulic oil is reduced again and the hydraulic oil is conveyed to the main oil tank by an oil return pipeline. The energy-saving environmental-friendly noise reduction system is applied to the hydraulic mechanism, has functions of energy saving, consumption reduction, noise reduction and environmental-friendliness and has a wide industrial application value.

Description

technical field [0001] The invention relates to a hydraulic and fluid mechanical noise reduction system, in particular to an energy-saving, environment-friendly and noise reduction system applied to a hydraulic mechanism. Background technique [0002] Noise is a sound that makes people sound uncomfortable and disturbing, and directly endangers human emotions, health and the surrounding environment. In addition to the harm to the human body, the noise generated by hydraulic components and systems will also cause damage to hydraulic components and affect their service life. In some cases with high precision requirements, it will directly affect the quality of the system. Fluid noise and mechanical noise are common in hydraulic components and systems, and fluid noise is the focus of research on hydraulic noise control. Fluid noise is basically divided into four types: cavitation noise, vortex shedding noise, pressure shock noise and pressure pulsation noise. Among them, fluid...
