Two-way balance hydraulic cylinder oil cylinder description:

Methods of improving the quality of the sleeve oil cylinder:

There is a big difference in the overlap between post-plating polishing and post-plating polishing. Especially the mass production is more obvious. Strictly clean the burrs and burrs of mechanical components, in particular, the finishing of sealed bores in the cylinder uses rolling. Can significantly improve the fatigue strength and stress corrosion resistance of the cylinder surface. The stress on the surface of the friction pair is generally controlled between Ra0.4 ~ 0.8.When the oil cylinder is installed, the connection place of the oil cylinder cannot be fixed. Due to the effects of hydraulic pressure and thermal expansion in the cylinder, there is expansion. Will cause deformation of various parts of the cylinder. When disassembling or disassembling the hydraulic cylinder, use a hammer to hit the cylinder barrel and piston surface. If the cylinder bore and piston surface are damaged, they can be sanded with sandpaper and carefully polished with fine oil stone.

During the use of the guide sleeve and the piston rod cylinder, such problems sometimes occurs. The hydraulic cylinder cannot be operated immediately after the hydraulic cylinder operation command is issued. It should take a short time before you can move or sometimes move and stop, shows irregular operation. 

The cause of this fault and the troubleshooting method are mainly air in the hydraulic cylinder.

Remedy: Exhaust through the exhaust valve. Check if there is suction air in the seal ring on the moving part of the piston rod. If so, replace the seal ring.
