When the hydraulic press just bought the noise is good, gradually the longer the noise is greater, the noise of the hydraulic press how to solve it.
1. Selection of low-noise hydraulic components
Specific measures: hydraulic machine selection of low noise hydraulic pump and control valve; reduce the speed of hydraulic pump, the goal: to reduce the noise of a single hydraulic component.
2. Reduce mechanical noise
Specific measures: improve the processing and installation accuracy of the hydraulic pump unit of the hydraulic press, adopt flexible coupling, and adopt integrated connection without pipe and telephone; The vibration isolation body, anti-vibration pad and hose section are used for pump inlet and outlet. The hydraulic pump unit is separated from the oil tank; The oil tank is provided with reinforcing ribs; Reasonable determination of pipe length and pipe clamp configuration.
3. Reduce fluid noise
The hydraulic components and pipe fittings are well sealed to prevent air from entering the hydraulic system; Eliminate the air mixed into the system; Adopt anti-noise oil tank structure; Reasonable piping, the oil tank is installed higher than the hydraulic pump, and the pump suction system can be improved; The pressure valve is gradually lowered; Add an oil drain throttle valve or set a pressure relief circuit; Reduce the reversing speed of the reversing valve and adopt DC electromagnet; Change the pipe length and pipe clamp position; Adopt accumulator and muffler to absorb sound; cover the hydraulic pump or the entire hydraulic station, invade the pump in the oil, and select materials reasonably to prevent noise from spreading in the air; absorb noise and reduce noise.
