One fluorine rubber rubber O-ring temperature best rubber products
Rubber O-ring can withstand high temperatures, more commonly used silicon rubber O-rings and Viton O-rings. The so-called high-temperature O-ring, we must understand the normal use temperature O-ring is the number, select the appropriate O-ring material, depending on the temperature range. Fluorine rubber O-ring temperature limit of 240 degrees, we recommend long-term use at temperatures below 220 degrees, it can be said fluorine rubber O-ring is one of the best rubber products. Silicone rubber O-ring temperature limit of 250 degrees, we recommend long-term use at temperatures below 230 degrees. If the primary is in die-casting mold cooling water seal with the words, with silicone rubber O-ring or fluorine rubber O-rings can all be used. If the oil is not required, you can choose EPDM O-ring, which is EPDM O-ring. Resistant pure natural gas, the general rubber O-rings can be used basically. [View Details] -
Y-shaped hydraulic seals are commonly used in hydraulic reciprocating motion of the sealing element
Y-shaped hydraulic seal is one of the commonly used hydraulic reciprocating motion of the sealing element, it not only determines the sealing performance of the hydraulic system, but also affect ancillary mechanical equipment performance and service life. Due to the high cost of reciprocating seal test, a long time, such a large investment in human sealing performance based on ANSYS attention. [View Details] -
1. Hydraulic Seals material (material) good flexibility, particularly the requirements of good resilience, permanent deformation should be smaller.

Note 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.

Friction characteristics of a hydraulic problem O-ring and the basic requirements
Domestic and foreign scholars on the stress distribution of hydraulic installation and use of O-rings in contact failure form had extensive theoretical research, and carried out experimental analysis of hydraulic O-ring friction mechanism under water lubrication conditions and seal pressure, compression experimental study of the amount of friction and slip velocity on the law.

Dust-proof rubber O-ring Practical features
Dust-proof rubber O-ring with automatic elastic compensation feature that automatically eliminate the gap generated when the dust ring wear, coupled with high wear resistance and dust ring material, its working life doubled. Non-metallic dust and dust rubber O-ring low friction, high wear resistance and high strength ring can prevent silt embedded, without causing dust surface, so good scraper effect, especially for poor working conditions and sticky dirt, polluting the workplace; [View Details] -
With the gap in the cylinder head and the piston rod 0.03 ~ 0.05mm. O-ring seal mounted hydraulic easy extrusion, clamping cylinder working stroke short at 15 ~ 20mm, less seal wear.

Specific rubber O-ring implementation process
(1) selection of seal size ?50mm?3.1mm more in line with the requirements, but considering to increase seal life for all, or choose to seal ?50mm?3.5mm can meet the requirements of the rubber O-ring seals have a certain amount of pre-compression, so that you can increase the seal All life.

Hydraulic seal oil resistance properties as the first recipe
Hydraulic seal oil resistance, in the course of chemical stability. If the chemical stability below standard, because the chemical structure of the rubber effect of the oil medium is changed, resulting in other physical properties change: such as strength, deformation, hardness, elasticity, performance degradation, or is completely lost. Thus, the hydraulic seal oil resistance is the first performance of the formulation. [View Details] -
The mechanical properties of rubber seals
Rubber seals mechanical performance than the usual high-density polyethylene. It has outstanding impact resistance, stress cracking resistance, high temperature creep resistance, low coefficient of friction, self-lubricating properties, excellent chemical resistance, fatigue resistance, noise damping resistance, radiation resistance and the like.
