Cylinder fault basic maintenance skills

Cylinder in the process of action, can't say that any part of the body in its journey, so as not to hurt. In the cylinder in the maintenance of the equipment, you must first remove gas source, gas discharge, to ensure that the cylinder running until equipment in the stationary state. In the maintenance of the cylinder end, should check any part of the body is not placed within the scope of its stroke, can open air test run. , when the air is part of the gas should be rushed into the air and make the cylinder rushed to its original position, and then connected to the plug. Use of cylinder block stomatal aperture with the hand, then remove the plug shaft by hand and the widening of reaction, on the piston will automatically rebound in situ; Pull push rod and block pore, large reaction also press the push rod with the hand, on the piston automatically rebound. Bad cylinder can't pull resistance or resistance is very small, in front of the piston movement or action to slow, pull out and reaction, but continuous slow decline; Small pressure, no pressure, pressure, but pressure is small. Discovered sealing ring and cylinder cover, remove the cover, remove the circlip, remove the push rod, remove the sealing ring, clean all parts, check the degree of wear and tear. If there is a slot, grinding smooth, prevent leakage and ensure not to increase sealing ring wear. Install the new sealing ring in the right direction, and painted in oil on the surface. According to remove the steps to install cylinder seal check cylinder in turn. After opening the cylinder, it is necessary to evaluate the values of the component. If the push rod or cylinder wear very much, for a new sealing ring cannot be used for a long time. Push rod, cylinder and sealing ring seat deformation, beyond repair.
