On the one hand, it is necessary to check the quality and installation of the cylinder, including whether there is any leakage; whether the bolts of the installation and assembly parts are loose or not, to prevent accidents. Secondly, in the case of an adjustable buffer device, and the piston is in motion, the throttle valve should be placed in a small flow position, and then the throttle size should be gradually adjusted until the requirements are met.
It is also necessary to adjust the exhaust device used in conjunction with it. The specific method is to first reduce the working pressure in the cylinder to (0.5--1) MPa, then reciprocate the piston rod and open the exhaust plug for exhaust. When the vent plug is exhausted, the humming sound can be heard, and then the white turbid foamy oil is sprayed, and the oil ejected when the air is exhausted is clear.
