[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. 4 hours of continuous operation, such as timing closure, 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, light oil is not more than 10 drops / min, such as 2-3 days, still no signs of improvement 109-60 mechanical seal, you should check the seal pump stops devices. [Three rain valve to recommend the star product - Mechanical seal] Introduction: Advantages a reliable sealing in the long run cycle 109-25 mechanical seal, seal state is very stable, very small amount of leakage, according to rough statistics, the leakage amount typically only 1/100 of soft packing seal; 2, long life oil, aqueous medium generally up to 1 to 2 years or longer 109-55 mechanical seal, usually in the chemical medium can reach six months above; 3, friction power consumption is small mechanical seal friction power is only soft packing of 10% to 50%; 4, the shaft or sleeve essentially from wear and tear; 5, after the long repair cycle can automatically compensate for face wear, general Under the circumstances, no need regular maintenance; 109-40 mechanical seals, mechanical seal 109 selected three rain (already certified, Qiqihar mechanical seal is provided by Valve Co., Ltd. Tianjin three rain Valve Co., Ltd. Tianjin three rain. (www.tjsymf.com) is a leader in Tianjin, seals, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In three rain valve leadership with the staff Warm welcome to all inquiries negotiations to create three rain valve a better future.
