Use of mechanical seal
Want to switch to the conventional packing mechanism to mechanical seals? Well, it is certainly a great decision.
Because of immense benefits, the modern engineering processes prefer it over the traditional methods. Here is the fundamental understanding of the mechanical seal, its components, and use.
Why are Mechanical seals quite popular in the modern engineering?
The mechanical seal is widely used because they offer excellent prevention against the leakage of fluid as compared to other methods.
It seals the rotating part of the shaft against the stationary component of the pump or other mechanical devices.
Several varieties of mechanical seals are there to choose from. The choice depends on the functionality and application.
Engineers choose the appropriate type after checking the functional needs and operating conditions.
What makes a mechanical seal ideal?
A mechanical seal prevents the leakage of the fluid to the external surroundings. It seals the rotating part against stationary one. Experts give a good score to it because:
- The leakage is near to zero (though some leakage is necessary for lubrication). Hence, these seals are ideal for processes that use harsh chemicals like HCL or Sulfuric Acid, or toxic compounds.
- The improved throughput of the pump as the mechanical seal offers low frictional drag. Also, there is a significant drop in the power consumption.
- Longevity of the mechanical components. The sleeves and shafts do not wear out fast.
- If installed well, mechanical seals reduce the need for preventive maintenance. The seals are quite robust and long-lasting.
- Mechanical seals can bear high speeds and pressure than the conventional methods of packing.
- They are available in the wide spectrum of design specifications to suit all varieties of pumps and other machines.
Components of the mechanical seal
Though the components vary depending on the application and type of the mechanical seal, here is an example of a typical mechanical seal:
- The rotating face: It is the part connected to the rotating shaft. It is the moving component and a vital part of the seal.
- The fixed face: It is the motionless part which is connected to the pump housing.
- Secondary sealants: In between the two faces of the mechanical seals shaft and insert mountings work as the secondary sealant. The examples are wedges, V-ring or O-ring.
- Hardware: Examples of hardware used in the mechanical seal is pins and bellows, compression rings and gland, etc.
The mechanical seal has replaced the earlier methods completely because it is far more superior and better than the conventional seals.
It can sustain aggressive operating conditions such as high temperature and pressure, and toxic or corrosive fluids.
When you switch to this mechanism, it assures prevention against fatality, accidents as well as environmental damage.
From operation engineers to the maintenance department, everyone is happy with it. No more downtime because of wear and tear or leakage, and there is a great saving on operational cost.
However, just ensure you consult an expert before switching to it. You must be sure about what you are investing into is what you need.
