Hydraulic piston rod machining quality control standard
Jun 07, 2018

The hydraulic piston rod is a connecting part that supports the piston to do work, and most of them are used in the cylinder and the cylinder movement execution part, belonging to a moving part with frequent movement and high technical requirements. Taking a hydraulic cylinder as an example, it is mainly composed of a cylinder barrel, a piston rod, a piston, and an end cap. Therefore, the quality of the hydraulic piston rod directly affects the life and reliability of the entire product.


Under normal circumstances, the hydraulic piston rod processing quality requirements are more stringent, requiring its surface roughness Ra0.4 ~ 0.8um between, but also on the coaxiality, wear resistance and strict requirements. In addition, the basic feature of the cylinder rod is the processing of the elongated shaft, which is difficult to process, so the entire machining process is more complicated for the processing personnel.


In practical applications, the use of hydraulic piston rods is not only closely related to the processing technology, but also has a close connection with daily use and maintenance. As a user, do you know how to perform daily maintenance and maintenance of the piston rod? Next, we will specifically introduce some methods for maintaining the piston rod. If the piston rod is formed by roll forming, a layer of cold hardened layer is formed on the rolling surface, thereby reducing the elasticity and plastic deformation of the grinding auxiliary contact surface, thereby improving the wear resistance of the surface of the cylinder rod and avoiding Burn caused by grinding.


For hydraulic piston rod products manufactured by rolling process, during routine maintenance, the hydraulic oil tank filler cap must be dismantled first, then the filter cap should be dismantled, and the inspection hole and hydraulic oil pipe and other components should be removed. However, when the system oil gallery is exposed, it must avoid dust, and the disassembly site must be thoroughly cleaned before it can be opened.


CAUTION During daily work, the surface of the hydraulic piston rod should be periodically cleaned. When removing the hydraulic fuel tank cap, remove the dirt around the fuel tank cap. After loosening the fuel tank cap, remove any debris that remains in the joint and confirm that it has been cleaned. Only then can you open the fuel tank cap. The hydraulic piston rod is cleaned and then assembled.http://www.xhychromerod.com/
