Forging equipment is used more and more in life, hydraulic parts is one of its components, so how to solve its noise fault? 

Let's give you a specific introduction. 

1. Excessive wear of the internal components of the hydraulic pump, such as wear and tear of the cylinder block and distribution plate, plunger and plunger hole of the piston pump, resulting in serious leakage in the hydraulic pump, flow pulsation will occur when the hydraulic pump outputs high pressure and small flow oil. 

Cause high noise. 

In this case, the deflection angle of the pilot system variable mechanism can be appropriately increased to improve the influence of internal leakage on the output flow of the pump. 

Second, the servo valve spool of the hydraulic pump and the piston controlling the flow rate will also pulsate during the movement of the piston due to local wear and strain, resulting in the fluctuation of the output flow and pressure of the hydraulic pump, resulting in greater vibration and noise at the outlet of the pump. 

At this time, the components with serious wear and tear can be treated by brush plating or replacement. 

Third, the distribution plate of hydraulic pump is also one of the important components which are easy to cause noise. 

In use, due to surface wear or sludge deposition at the opening of the unloading tank, the unloading tank will be shortened and the unloading position will be changed, resulting in the phenomenon of oil trapping, which will lead to higher noise. 

4. In the process of normal repair, the distribution plate repaired by flat grinding will also have the consequence of shorter unloading groove, if it is not properly slender in time, it will also produce a lot of noise. 

In the process of assembly, the large unloading slot of the distribution plate must be installed in the high pressure cavity of the pump, and its sharp angle direction must be opposite to the rotation direction of the cylinder block, otherwise it will also bring more noise to the system. 

The above is to solve the forging equipment in the hydraulic parts noise fault methods, I hope to help you, if you want to know more knowledge, welcome to contact us, we will serve you wholeheartedly.
