What is the source of noise from hydraulic hammers

Once the crushing hammer is in high intensity operation for a long time,it is prone to some malfunctions,and noise is the direct response to the malfunction.There are generally three main factors that generate noise:aerodynamic,mechanical transmission,and hydraulic components.But many users do not know what the noise source of hydraulic hammers is.Next,the editor will provide a detailed introduction to everyone:

1、Noise in the transmission system

The noise of the transmission system comes from direct mechanical friction between gears.During use,attention should be paid to the decibel of noise.If the sound is abnormal,it is necessary to promptly increase lubrication or check for wear.

2、Engine noise

During the start-up process of large mechanical equipment,the engine may produce significant noise,and aerodynamic noise is an important component.Therefore,we need noise reduction measures as the main way to solve the problem.

3、Hydraulic noise

The vibration and noise in the hydraulic system are accompanied by vibration and noise,mainly due to the sudden changes in the clearance between them and the lateral force borne by the reciprocating piston.In this regard,piston clearance,piston pin hole offset,piston height,number of piston ring,cylinder liner thickness,lubrication conditions and other aspects can be improved.

Structurally,it can be divided into engine noise,transmission noise,hydraulic noise,vehicle body noise,noise caused by the connection and coordination of chassis components,braking system noise,operating impact noise of working devices,etc.Among them,the noise generated by the engine and its related components accounts for more than half.Therefore,vibration reduction and noise reduction of the engine have become one of the key factors in noise control of engineering machinery.
