Seals The Main Seal Is Subjected To System High Pressure Characteristics
Jan 06, 2017

Seal The main seal to withstand the system should have the characteristics of high pressure:

By analyzing the hydraulic system, the main seal to withstand the system pressure, should have the following characteristics:

(1) high-pressure, the sealing material should have a high mechanical strength.

(2) low friction and wear, sealing material should have a lower coefficient of friction and mechanical seal high wear resistance, seal design to ensure that it mechanical seal in a better lubrication conditions work.

(3) return oil capacity, to ensure that the oil film brought back in the back when the system can be internal to achieve dynamic balance to prevent the formation of back pressure.

(4) pressure relief function, that is, a one-way valve seal function, the system pressure is low or reduced to zero, if the back pressure has been formed immediately down to prevent the phenomenon of trapped oil.
