Note hydraulicNote hydraulic seal damage prevention

 

If the compartment pressure hydraulic seals aging, should be replaced with new parts: relief sheet gasket should be installed on the suction chamber (port) side (low pressure chamber), and to ensure a certain degree of preload pressure. As pressure mounted on the liquid chamber side, hydraulic seals will soon be damaged, causing high pressure chamber communicates with the low pressure chamber, the hydraulic pump incapacity.

 

More hydraulic reversing ring and seal retainer. Note, however, the choice of hydraulic seal surface should be smooth; no wrinkles, no cracks, no holes, no scratches.

 

Regret round too serious, can be taken to increase the replacement of hydraulic piston ring sealing its way to recovery; if roundness, cylindricity error exceeds 0.05mm, then respond cylinder honing process, replace the piston to increase to return to normal with the gap.

 

Hydraulic compression ring size can directly affect the sealing performance and service life, the amount of compression is too small, the sealing effect is not good; the amount of compression is too large, the hydraulic seal ring assembly adverse, increasing frictional resistance movement, life will be shortened . Therefore, seal design process, to control the amount of compression of the reasonable good hydraulic seal rings, generally 7% to 30% compression rate prevail. Diameter compression section of a hydraulic mounting ring 5% to 3.5%, for the fixed value is too large to obtain seal, for sealing activities taking small value.

 

Axial sliding surface oil spills, it is more difficult to solve. Election dust resistance, wear resistance, low temperature performance and to ensure a good hydraulic seal ring groove dimensions and accuracy, the correct choice of the roughness of the sliding surface, dustproof bellows, try not to make the hydraulic cylinders bear partial load, often rub in addition to the dust on the piston rod, avoid bump, scratch, do a good job managing the cleanliness of the hydraulic oil.

 

High oil temperature and hydraulic seals and hydraulic oil incompatibility deterioration. High oil temperature is a common situation, the greater the depth from the ground, the oil temperature will be higher. Chemically stable PTFE material may also stand up to such a high temperature test, began defeated. seal damage prevention
