What are the main factors affecting the performance of internal high pressure seals

　Internal high-pressure seal is widely used in the need for sealing industry, what are the main factors affecting the performance of internal high-pressure seal.

　　1, what are the main factors affecting the performance of the internal high-pressure seal, movement speed moving speed is very low, to consider the smoothness of the operation of the device and whether there is crawling phenomenon. When the moving speed is very high), the device lubrication effect of the ink may be destroyed, due to the failure of good lubrication, the seal may be friction and heating, which leads to a much lower life. It is recommended that the rubber seal in the speed range of 0.3m / s ~ 1.2m / s is more appropriate.

　　2、Low temperature will reduce the elasticity of the rubber-plastic composite seal, causing leakage and even make the whole oil seal hard and fragile. High temperature will make the volume of the oil seal expand and soften, resulting in a rapid increase in the frictional resistance of the oil seal movement and a decrease in pressure resistance.

　　3、The main factor affecting the performance of internal high pressure seal is what working pressure. Whether there is a start pressure sealing requirements. The required low voltage operation to be used in the low friction performance of the seal with low pneumatic resistance. At or below 2.5Mpa, compound seal rubber is not appropriate to consider, where the high pressure compression seals, to resist extrusion ring groove processing has special requirements.

　　4, the main factors affecting the performance of the internal high-pressure seal is what the working medium, the need for strict requirements in accordance with the production of enterprises The manufacturer's recommendation of some advice selected to study the working environment outside the medium, it is vital to maintain the work as the clean development of the medium. Oil aging or pollution problems will not only make the management system between the components failure, accelerate the aging and wear of the oil seal, and for which the spoil may scratch or embedded in the seal, so that the seal failure. We have to check the oil seal quality analysis and its cleanliness regularly, and replace the oil filter or fluid according to the maintenance specification of the equipment. High compression of air trapped in the fluid in the cylinder can generate high temperatures that can burn or even carbonize the seals. Avoid the use of the situation occurs constantly, in the hydraulic control system safe operation of the initial, should be designed exhaust treatment. The hydraulic cylinder should also run slowly at low pressure for several minutes to confirm that the residual air in the fluid has been exhausted before normal operation.
