The Effect Of Mechanical Sealing Of The Fundamental Components

1) Face collision pairs (static and moving rings)

The collision pair should be tightly fitted to form a sealing surface to avoid media leakage. This request pump mechanical seal conflict pair to have excellent wear resistance; The moving ring can move axially, actively compensate the wear of the sealing surface, and make it fit with the static ring excellently; Static ring has floating and buffering effect.

2) Elastic elements (spring, bellows, barriers, etc.)

It is the main effect of compensation, pre-tightening and buffering, but also on the sealing face of a reasonable ratio of pressure factors. Request it with mechanical seal always adhere to the elastic to overcome the auxiliary seal and transmission parts of the conflict and the inertia of the moving ring, to ensure that the end conflict pair outstanding fitting and moving ring compensation effect.

3) Auxiliary seals (O-ring, V-ring, wedge ring and other special-shaped sealing ring)

It mainly plays the sealing effect of the relative stop parts, and also plays the floating and buffering effect. The auxiliary sealing element of the static ring can ensure the sealing between the static ring and the gland and make the sealing ring have a certain buoyancy; Request the auxiliary sealing element of the moving ring to ensure the sealing between the moving ring and the shaft sleeve. The data should be heat - resistant, cold - resistant and compatible with medium touch.

4) Transmission parts (transmission pin, transmission ring, transmission seat, transmission sleeve, transmission key)

It plays the effect of transferring the shaft torque to the moving ring; The drive pin, press ring, drive ring, drive pin and drive seat of the center drive all play a driving effect. Data request Corrosion and wear resistance.

5) fixing parts (set screws, spring seat, gland, assembly sleeve, shaft sleeve)

It plays a static and dynamic ring positioning, fixing and dressing effect. Request it to be positioned accurately, ensure that the sealing surface of the conflict pair is in an accurate position, and adhere to the tension spring ratio of outstanding fit. Together with the request for convenient disassembly, easy to place, can repeat the effect, and auxiliary sealing cooperation should pay attention to the device sealing ring chamfering and ring pressure elasticity, especially should pay attention to the moving ring auxiliary sealing ring and shaft sleeve cooperation in corrosion resistance, wear resistance, if necessary, can take hard surface coating.
