Describe difference between mechanical seal and oil seal – Whether it is a mechanical seal or oil seal, it prevents the fluid seeping the liquid to other parts of the machine, or it keeps the rotating parts lubricated.
Both sealing types are popularly used in different mechanical engineering applications. How are they different? The article explains the fundamental working mechanism of both categories of seals.
The mechanical seal is used in a pump, mixer and other mechanical engineering scenarios to contain the fluid within a vessel where a shaft rotates through a stationary (or rotating) housing.
Why is mechanical seal important in this situation? It is because the rotating shaft has to move in a wet environment, but there should not be the leakage of pressurized fluid. Hence, the role of a seal is quite critical.
Does it mean the seal stops the leakage completely? Well, on the practical grounds yes because there is no ‘visible leakage’.
There is a little leakage as the fluid vapors get released into the atmosphere from the faces of the seal, though. Since the quantity is hardly quantifiable, the seals are considered leak proof.
Oil seals close off the space between stationary and moving components in the mechanical equipment. It saves the lubricant from escaping through the equipment and ensures smooth operation of the machine.
Oil seals are called rotary shaft seal or radial lip also.
Since oil seals are versatile and multipurpose, they are suitable for all types of mechanical engineering situations, e.g., manufacturing units, automobiles, pumps, etc.
When there is a need for rebuilding a cylinder and pump instead of building a new one.
It is possible to get custom-made seals manufactured at reasonable rates from good-quality manufacturers if the readymade seal specification doesn’t meet the requirement.
It is critically important that you choose the appropriate seal for an application. The seals should be ordered from a manufacturer of high repute. To get the best seals, it is important to give accurate design specifications. We describe the difference between mechanical seal and oil seal here.
