Mechanical seal installation considerations - 2020
2 mechanical seals play an absolutely important role, the installation of mechanical seals, there were many small details to attention, or it will cause the damage of the seal, and at the same time is also significant for mechanical hazards, so what we need to pay attention to when installation?
First to determine the size, carefully the instructions, determine the good size.
Then, before the installation for the parts will be ready to complete, to ensure the good performance, seal, shaft, such as scrub clean, want to reduce the friction resistance, can be coated in a layer of lubricating oil, if oil not easily, can clean soap and water.
Finally, the static ring is installed on the shaft, as far as possible don't run into machinery, mechanical seal after market place position must be strict on tight.
You may be interested in the article: during the period of pump shaft rotation, mounted on the shaft seal ring sealing surface and the opposite of static friction ring seal faces.
The contact between the two sealing interface similar bearings, and wear.
Any form of system leaks must be through the sealing contact surface.
Effect on axial force that seal ring always keep contact friction, its source can be mechanical or hydraulic pressure, in a lot of design, take the sum of the both.
The stable contact can prevent from the friction surface leakage or leakage to small.
Is different from the kettle with mechanical seals, pumps with mechanical seal sealing medium is liquid, the mixture of solid and liquid and more atmospheric gases, etc. ;
While cauldron-using machinery seal used in high pressure gas or liquid gas mixture, leak and biological cause serious threat to the environment.
Pumps with mechanical seal are delicate, complex mechanical structure is one of the basic element, is the key to the pump mechanical parts.
The sealing performance and service life depends on many factors, such as selection, the precision of the machine, the correct installation use, etc.
There are many different kinds of pumps with mechanical seal.
Different models, its maintenance is difficult to discern and judgment.
