Prevent twisting the rubber O-ring Notes

　　Prevent twisting the rubber O-ring Notes

　　1) Install the rubber O-ring groove concentricity size, should not generate distortions from the convenience and processing two aspects to consider.

　　2) The cross-sectional dimensions should be uniform, and at each installation site should be fully applied in the sealing oil or grease. Sometimes you can use the felt impregnated with lubricating oil refueling device.

　　3) Under the conditions permit, we should try to increase the cross-sectional diameter, dynamic seal ring with cross-sectional diameter should generally be greater than the static seal; in addition, imports of rubber O-ring is used to avoid the large-diameter piston seal.

　　4) at low pressure also distorting damage, it can be used in conjunction with the ring.

　　5) reducing the cylinder and the piston rod surface roughness.

　　6) the use of low friction coefficient material seals.Ring

　　7) Under certain circumstances, it can not easily produce distortions instead of the rubber O-ring.
