[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 mechanical seal should be smooth 113-60, 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] Introduction: HG9 type mechanical seals are single end mechanical seal, unbalanced rubber bellows structure, HG9 type mechanical seal its compliance with DIN24960 standard G60, G50 line with European standards, G55 in line with US standards, its floating regulation performance, can enhance or reduce the number of turns of the spring, to accommodate axial installation requirements, simple structure, easy installation 113-48 mechanical seal, good performance, is recognized by the international authoritative pump factory, by users. Vice friction materials and auxiliary materials were selected according to the actual working conditions. Scope: Sealed Medium: cold water, hot water, beverages, weak acid weak base, with a variety of media particles. Seal chamber pressure: ≤0.8Mpa sealed chamber temperature: -20 ℃ ~ 140 ℃ line speed: ≤10m / s 113-65 mechanical seal, mechanical seal selection Tianjin rain (certified), Karamay mechanical seal pumps from Tianjin three rain Valve Co., Ltd. offers.
