Analysis of the noise caused by the failure of the hydraulic parts

Analysis of the noise caused by the failure of the hydraulic parts The failure of hydraulic components leads to noise and suction. It is one of the main reasons for the high noise of hydraulic pumps. The distributor of hydraulic pumps is also one of the most important components that easily cause noise. Here we will introduce in detail.
1. plunger pump or motor noise
(1) the phenomenon of air suction is one of the main reasons for the high noise of the hydraulic pump. When the air is mixed into the air, it is easy to form cavitation phenomenon in its high pressure area and propagate in the form of pressure wave, resulting in oil oscillation, resulting in cavitation noise. The main reasons are as follows:
(1) the oil filter of the hydraulic pump, the plugging of the inlet pipe or the high viscosity of the oil can cause the high vacuum at the inlet of the pump to make the air infiltrate.
(2) the damage of the oil seal on the shaft end of the hydraulic pump, the pilot pump, or the bad seal of the inlet pipe, resulting in the air entry.The oil level of the oil tank is too low to make the hydraulic pump suck into the air directly.When there is high noise in the work of the hydraulic pump, the above parts should be checked first and the problem should be dealt with in time. (2) the internal components of the hydraulic pump excessive wear, such as piston pump cylinder and valve plate, the plunger and the plunger hole with pieces of the wear and tear, injury, make a serious leak in the hydraulic pump, when the hydraulic pump output pressure and flow pulsation will produce small flow oil, causing high noise. At this time, the deflection angle of the pilot system variable mechanism can be appropriately increased to improve the effect of internal leakage on the output flow of the pump. The servo valve spool and the flow control piston of the hydraulic pump will also cause the piston to fluctuate during the movement due to local wear and tear. It will cause the fluctuation of the output and pressure of the hydraulic pump, resulting in larger vibration and noise at the outlet of the pump. In this case, the brush plating and replacement can be done for the elements with serious wear and tension.
(3) the flow plate of the hydraulic pump is also one of the most important components of the noise. Because of the surface wear or sludge deposition at the opening of unloading groove, the unloading slot will be shortened and the unloading position will be changed, resulting in the phenomenon of trapped oil, which will cause higher noise. During the normal repair process, the disc repaired by flat grinding will also have the consequences of shortening the unloading slot. If it is not properly slender in time, it will also cause great noise. During the assembly process, the large unloading groove of the distributor plate must be installed in the high pressure chamber of the pump, and the direction of its sharp angle must be opposite to the rotation direction of the cylinder block, otherwise, it will also bring great noise to the system. 2. hydraulic cylinder noise
(1) the air in the oil liquid or the air in the hydraulic cylinder is not completely exhausted, and the cavitation phenomenon is produced under the action of high pressure, which causes large noise. At this time, the air must be exhausted in time. (2) the oil seal of the cylinder head is too tight or the piston rod is bent. In the process of movement, the noise will be caused by the strength of the cylinder. At this time, the oil seal or the straightening piston rod must be replaced in time.
3. pipe noise
Too much pipe dead bending or fixed clip loosening can also produce vibration and noise. Therefore, arrangements should be in the pipeline to avoid dead corner Nagarze to loose to be timely tightening.
Noise of 4. overflow valve
The overflow valve is prone to generate high frequency noise, mainly due to the unsteady performance of the pilot valve, which is the noise generated by the air vibration caused by the high frequency oscillation of the pilot valve's front chamber. The main reasons are as follows:
(1) the air is mixed with the oil, and the cavitation phenomenon is formed in the front of the pilot valve, which causes the high frequency noise. At this time, the air should be exhausted in time to prevent the air from reentering the outside world. (2) during the operation of the needle valve, excessive wear is caused by frequent opening. The conical valve and the valve seat can not be tightly closed, causing the noise of the pilot flow to be unstable and generate pressure fluctuations. At this time, it should be repaired or replaced in time.
(3) the pressure regulating function of the pilot valve is unstable due to the fatigue deformation of the spring, which makes the pressure fluctuate and cause the noise, and the spring should be replaced at this time>
