[Three rain valve to recommend the star product - Mechanical seal] Introduction: mechanical seal operation: 1, the pump starts, if slight leakage, should be observed for some time. As four hours of continuous operation, the leakage is still decreasing, you should check the pump stops. 2, the operating pressure of the pump should be smooth, the pressure fluctuation is less than 1 kg / cm. 3, the pump is in operation, the phenomenon should avoid taking the time to avoid dry friction and sealing sealing surface damage. 4. Always check the seals. Operation, when the leakage exceeds the standard, heavy oil is not more than 5 drops / min, the light oil is not more than 10 drops / min, such as 2-3 days, still no signs of improvement, the pump should be stopped to check the sealing means. [Three rain valve to recommend the star product - Mechanical seal] Description: seal failure main reasons: the sealing surface of the mechanical seal is opened when the repair, 85 percent of seal failure is not due to wear and tear caused by mechanical seal, but had worn before leaked. When the sealing surface is opened, the medium of solid particles into the sealed surface under the action of the liquid pressure, the sealing surface is closed, these solid particles can be embedded soft ring (usually right ink ring) of the surface, which has become a real " Wheel "will damage the hard ring surface. Due to the tightening ring or rubber ring on the shaft (sleeve), when the shaft when moving string 109-55 mechanical seal, ring 109-25 laminating machine can not be blocked, leaving open the sealing surface and the sealing surface of the lag closed, causes the solid particles into the sealing surface. There are also between the shaft (sleeve) and the sliding parts have solid particles affect rubber ring or ring slide (relative dynamic seal point, common fault). In addition, the media also have a rubber ring and the shaft (sleeve) crystals friction parts, there will be in the spring at the solid material, will open the sealing surface. 109-55 Shuangyashan mechanical seal mechanical seal _ _ mechanical seal manufacturers selected three rain provided by Valve Co., Ltd.
