What is the principle of mechanical seal?
A mechanical seal consists of 2 principle components. One component is stationary and the other rotates against it to achieve a seal (Figure 2). There are many types of mechanical seal, ranging from simple single spring designs to considerably more complex cartridge seal types.
What are the three types of mechanical seals?
Mechanical seals are critical components in centrifugal pump systems….The most common seal types include the following:
- Balanced seals.
- Unbalanced seals.
- Pusher seals.
- Non-pusher seals.
- Conventional seals.
- Cartridge seals.
What are mechanical seal components?
Every mechanical seal possesses five basic elements: One ring (usually the seal face) circulating synchronously with the rotating part (shaft) Secondary seal (usually O-ring) between shaft and ring. A stationary ring (usually the stationary seat) arranged in the stationary part (casing)
What are the functions of seal?
Seals are used to prevent the leakage of fluids in rotating equipment. A seal prevents lubricants, such as oil and grease, from entering the environment and (dirty) water from entering the installation.
Where are mechanical seals used?
They are used in various applications ranging from automobiles, ships, rockets and industrial plant equipment, to residential devices. Mechanical seals are intended to prevent the fluid (water or oil) used by a machine from leaking to the external environment (the atmosphere or a body of water).
What is the most common failure of a seal?
Improper installation is probably the most common cause of seal failure. Using the right tools is critical to prevent seals from being installed in the wrong direction or becoming damaged during installation.
How many mechanical seals are there?
8 Types of Component Mechanical Seals.
Why do we need mechanical seals?
Mechanical seals are the ideal choice when seal leakage is not an option for equipment or applications. This is usually the case when pump leakage can cause environmental or safety issues. Mechanical seals are much more durable than packing seals and are the better choice for long-term operation of your pumps.
