Hydraulic seal lasting deformation how to do?

??Because the use of hydraulic seal consisting of elastic rubber materials attributed to data, the initial planning of the compression and rebound blocked amount to the long-term use, decreased flexibility, lasting deformation occurs, resulting in seal decline, after the onset of the leak.

??High temperatures can accelerate the aging of rubber. The higher the operating temperature, the greater the hydraulic seal compression variables. When persistent deformation greater than 40%, the hydraulic seal hydraulic seal on lost and can attack the leak.

??Low temperature elastic rubber materials will decrease, even disappear. Temperature hydraulic seal minus job, in the case of -50 ? ~ -60 ?, the low-temperature resistance rubber elastic material will be a sharp decline, set to lose elasticity.

??Pressure of the hydraulic system is an important factor causing the hydraulic seal lasting deformation. Construction machinery hydraulic system operating pressure has gradually improved, long equipment duty cycle. Long-lasting high pressure causes the hydraulic seal deformation.

??Sealing apparatus in motion, conflict and wear are important factors affecting hydraulic ring damage. Adding conflict forces, the O-rings between the hydraulic piston rod occurred heat, resulting in rubber aging, resulting in the failure of hydraulic seals, destroyed the sealing function. Heat also causes conflicts rubber adhesion, further increases the power of the conflict, constitutes a vicious circle.

??Distort refers to a hydraulic seal in the axial direction to change the attack scene, resulting in many seals distorted elements, the most important element is the piston therebetween. Piston and the cylinder gap uneven, migraine pain is too large. Hydraulic seal uneven cross-section diameter, and thereby forming various distorted and uneven force point attack. Other hydraulic equipment seals in the process, we must pay attention to the normal condition of the hydraulic seal, to avoid distortion of the device constituting the scene.

??Dynamic sealing devices because there is a certain gap between the kinematics and technical equipment and other factors, cooperative member. If the material is too soft hydraulic seal, and seal the gap is too large, under pressure of the hydraulic oil will cause hydraulic stress seal ring portion will set in motion the process of being cut off to form a hydraulic seal gap bites.

??Because there is a dash of accuracy and precision equipment error between the piston and the cylinder, it will increase the gap bites also have a greater impact, the higher the pressure of the hydraulic system, the smaller ring hardness, the scene was grim bite.

??Avoid bites gap approach; maintenance equipment on sealing gap must be strictly controlled, precision beyond the size of the error, must be timely replacement of parts, to be satisfied with the choice of ring stiffness targets. Also it can be equipped with proper protection seal rings.

??Seals, is an important element of mechanical parts, it is seals prevent fluid or solid particles between the surface and prevent leakage from adjacent binding and other foreign matter such as dust and moisture into the interior parts of the material or equipment parts in machinery and equipment we use plays an important role. Axially attack scene change, resulting in many seals distorted elements, the most important element is the piston therebetween. Piston and the cylinder gap uneven, migraine pain is too large. Hydraulic O-ring cross-section diameter is uneven, and thereby constitute each of the point of attack uneven distorted. Other O-rings in the process equipment, must pay attention to the normal status O-ring, to avoid distortion of the device constituting the scene.

??Dynamic sealing devices because there is a certain gap between the kinematics and technical equipment and other factors, cooperative member. If the O-ring material is too soft, and seal the gap is too large, under pressure of the hydraulic oil will cause hydraulic stress will be part of the O-ring set in motion the process of being cut off to form an O-ring hydraulic gap bites .

??Because there is a dash of accuracy and precision equipment error between the piston and the cylinder, it will increase the gap bites also have a greater impact, the higher the pressure of the hydraulic system, the smaller ring hardness, the scene was grim bite.

??Avoid bites gap approach; maintenance equipment on sealing gap must be strictly controlled, precision beyond the size of the error, must be timely replacement of parts, to be satisfied with the choice of ring stiffness targets. Also it can be equipped with proper protection seal rings.
