Maximum operating parameters pressure: ≤1.2MPa temperature: 0 ~ + 150 Maximum speed: 20m / s [three rain valve to recommend star products - mechanical seals] Introduction: Mechanical seals used in pumps, compressors, and so the reaction was stirred tank rotary fluid machine, H7F-20 mechanical seal, but also for gear boxes, valves, swivel joints, stern shaft seal. Thus, H7F-30 mechanical seal, mechanical seal is a universal shaft sealing device. Determining whether the elastic member with the axis, i.e., the use of a rotary spring or spring structure according to the size of the static speed value. When the speed <20-30m / s, Nanning mechanical seal, use spring rotary structure; when higher speed, unbalanced mass of rotating parts can lead to strong vibrations, use spring stationary structure.
