[Three rain valve to recommend the star product - Mechanical seal mechanical seal] Technical requirements: a good thermal shock resistance to this end, require materials with high thermal conductivity and a small linear expansion coefficient, to withstand thermal shock will not crack. Smaller coefficient of friction sealing ring should match the smaller coefficient of friction. Good self-lubrication in the event of a short work of dry friction, does not damage the seal faces. Thus, the sealing ring to have a good self-lubricating, sealing ring material and sealing fluid should have a good wettability. [Three rain valve to recommend the star product - Mechanical seal] Introduction: HU5 type mechanical seals according to DIN24960 standard 106-90 mechanical seal, mounted back to back in line with DIN24960 standard double mechanical seal mechanical seal, are part of a balanced, rubber bellows tubes, single spring, single face structure, by a rubber ring bellows-driven interference, floating, good spring also played the role of transferring torque. Vice friction materials and auxiliary materials should be selected according to the actual conditions. Scope: Sealed Medium: containing particles of waste water, oil, sewage. Seal chamber pressure: ≤1.6Mpa sealed chamber temperature: -20 ℃ ~ 140 ℃ line speed: ≤10m / s 106-85 _ mechanical seal mechanical seal selected three rain (certified) _ Foshan mechanical seal from Tianjin three rain Valve Trade Limited. 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.
