[Three rain valve to recommend the star product - Mechanical seal] Description: rubber into natural and synthetic rubber. Assistant general mechanical seals seals are made of a variety of synthetic rubber. Not the same synthetic rubber have different characteristics, and sometimes needs based on their rational use those properties to choose rubber. Some other information mentioned above, poly vinyl chloride because of its excellent chemical stability, heat resistance and low friction coefficient of the strengths of the mechanical seal, are widely used in a variety of temperature, pressure, corrosive media conditions. Choice of quenching methods available PTFE O-ring seal patience 58B-95 aircraft, the choice of filling approach can improve the stability of the wedge-shaped Teflon seals scale. At high temperatures, but also the choice of swelling graphite or metal hollow ring seals do adjuvant. [Three rain valve to recommend the star product - Mechanical seal] Description: preparation of construction machinery seal proposition before: Before mechanical seal advocate hydrostatic test, check the mechanical seal is not a leak appearance. If the leak is more, should try to find out the reason for cancellation. If still valid, you should disassemble and inspect equipment from scratch. General hydrostatic test pressure for 2 to 3 kg / cm. Press the pump rotation disk drive 58B-75 mechanical seal, check the light is not uniform. Such as hard disk drive, or not moving, you should check the equipment standards are not at fault, the device is not reasonable. Secondary seal; play a secondary seal, the secondary seal ring divided compensation and non-compensation of ring seals. It can be an O-ring, V-ring, wedge ring, rectangular ring, etc., used to seal the shaft seal and mechanical seal, mechanical seal and housing. 58B-110 mechanical seal, mechanical seal Baicheng, 58B series mechanical seal manufacturers selected three rain provided by Valve Co., Ltd.
