Seal hydraulic seal failure of the main performance
At high temperature and pressure conditions of high levels of H2S and CO2, seal hydraulic seal failure mainly for swelling and aging rubber material, causing hydraulic seal shape changes, restitution, seals inelastic, seals and equipment resilient contact between stress is released, resulting in acid gas leak.

Describes a combination of seals
Grid to circle: Glyd by rubber seals and filled PTFE quality seal square superposition use constituted, to circle grid can be divided into the hole with a grid to ring and shaft cell to circle, but their sealing mechanism is the same, according to its own deformation on the sealing surface higher initial contact stress, stop without pressure liquid leakage. Hydraulic cylinder working pressure oil so that the elastic deformation of the rubber seals extruded rubber seals square, making it close to the sealing surfaces, and the initial contact stress together and prevent leakage of pressure oil.

Swelling and aging hydraulic seal
Imports of hydraulic acid Xinhua Xu rubber products seals Xinhua Xu rubber products importing acid and alkali resistance EPDM rubber seals, acid-resistant seals, alkali resistance seal in the trench initial deformation (interference) its sealing capability is very important: [View Details] -
Rubber O-ring technology elements
In the same formulation, the supporting elements of advanced technology employed, such as: curing conditions, and other economic and technical points and the final production of the rubber O-rings are closely related. So, in the past a lot of rubber formulations, but the ratio of the material, if not reached some level of technology and process conditions, can not be regarded as a complete recipe. Selected through a small test with a rubber O-ring recipe, there may be chance, in order to ensure good formulations, it must be carried out in batch and pilot test. Finally reclassification recipe, be sure to prepare operating instructions, specific provisions to the various processes, while complying with technical specifications and test specifications. It is officially put into production use. [View Details] -
Y-shaped hydraulic seals have three sealed hydraulic reciprocating motion in the system: non-operating state, the state and the static pressure reciprocating state. Compression preload Nonoperating that is, after the Y-shaped hydraulic seal installation naturally occurring; hydrostatic working condition namely Y-ring constant hydraulic pressure is applied and the Y-shaped ring remains stationary working condition; reciprocating piston reciprocates work state that is (an inner and an outer stroke stroke constitute a work cycle) working condition. 3 operating state can be carried out by the ANSYS software simulation analysis, the author mainly analyzes static working condition, the initial finite element model of the piston rod to move axially and pressed Y-shaped hydraulic seal obtained.

Construction Machinery Hydraulic Seals
In the hydraulic system is running, the hydraulic oil in the air easily separated and invade the hydraulic system so that it reduces the efficiency in the work process, a "cavitation" phenomenon. When the air into the hydraulic system when the hydraulic oil easily lead to oxidation occurs, it is difficult to protect the quality of the hydraulic press. In the hydraulic machine when changing the hydraulic oil, which will not be completely discharged air to start work; pump suction nozzle not be closed, so that the exposed surface of the oil. In addition, too much water in the hydraulic system, resulting in various parts of the hydraulic machine elements subjected to corrosion, wear it aggravation, reducing the efficiency of construction machinery hydraulic system. [View Details] - Oil formulas to specifically addressed: oil formulation means that the formulation must be oil resistance as the first performance of the formulation. [View Details]
