Mechanical seal manufacturer Effect of the underlying element
The collision pair shall be closely fitted to form a sealing surface to avoid medium leakage. This requires that the pump mechanical seal should have outstanding wear resistance; The moving ring can move axially to actively compensate for the wear of the sealing surface, making it fit the stationary ring well; Static ring has floating and buffering effect.
2) Elastic elements (tension spring, bellows, barrier, etc.)
It plays an important role in compensating, pre tightening and buffering, and is also an element of reasonable specific pressure on the sealing face. Request it Mechanical seal for kettle Always adhere to elasticity to overcome the conflict between auxiliary seal and transmission parts and the inertia of moving ring, so as to ensure that the end face conflict pair fits well and the moving ring compensates.
3) Auxiliary seals (O-ring, V-ring, wedge ring and other special-shaped seals)
It mainly plays the role of sealing the relative stop parts, and also plays the role of floating and buffering together. It is required that the auxiliary sealing element of the stationary ring can ensure the sealing between the stationary ring and the gland and make the sealing ring have a certain buoyancy; The auxiliary sealing element of the request moving ring can ensure the sealing between the moving ring and the shaft sleeve. The data shall be heat and cold resistant and compatible with media touch.
4) Transmission parts (transmission pin, transmission ring, transmission seat, transmission sleeve, transmission key)
It has the effect of transmitting the shaft torque to the moving ring; The drive pin, press ring, drive ring, drive pin and drive seat of the central drive all have transmission effect. Data request corrosion resistance and abrasion resistance.
5) Fasteners (set screw, tension spring seat, gland, assembly sleeve, shaft sleeve)
It has the effect of positioning, fastening and packing of static and dynamic rings. It is required to locate it accurately, ensure that the conflicting sub sealing surface is in an accurate position, and adhere to the tension spring pressure ratio of excellent fitting. It is requested that the assembly and disassembly is convenient, easy to be in place, and can be repeated. Attention should be paid to the chamfer of the sealing ring with the device and the ring pressure, especially to the corrosion resistance and wear resistance of the auxiliary sealing ring with the moving ring and the shaft sleeve. If necessary, hard surface coating can be used.
