For MRO buyers: check this list of FAQs on mechanical seal
Mechanical seals for a very important part of the MRO inventory in many industries such as automobile factories and industrial units. Mechanical seals are used for preventing the fluid (water or oil) used by a machine from leaking. If you are an MRO buyer who wishes to know about mechanical seals, here is a list of frequently asked questions and their answers that you may find helpful:
Question 1: What is the main purpose of a mechanical seal?
Machinery that has a rotating shaft, such as pumps and compressors, needs mechanical seals on the power transmitting shaft. They are used in automobiles, ships, rockets and other machinery to prevent leakage of the fluid. In the absence of mechanical seals, the liquid will leak.
Question 2: What is the difference between a stuffing box and mechanical seal?
Though a stuffing box and mechanical seal serve the same purpose, mechanical seals are often preferred over a stuffing box. The axis of the stuffing box wears and needs lubrication to prevent wear. With a mechanical seal, the axis does not wear. There are hardly any leaks.
Question 3: Are seals and gaskets the same?
Both gaskets and mechanical seals are an important part of packing and sealing inventory. However, the two are not the same. Gaskets are used for creating a connection between two components that have flat surfaces. On the other hand, seals are used between parts that rotate.
Question 4: What is the first thing to consider when selecting seals?
Mechanical seals can operate for many years, provided they have been properly selected for their application. Here are a few factors that you need to consider at the time of selecting seals:
- Type of liquid will decide the material of the seal.
- Pressure will determine the size of the mechanical seals.
- Different seal materials are rated for different temperatures.
Question 5: What causes a mechanical seal to fail?
Some of the factors leading to the failure of a mechanical seal are:
- Poor lubrication
- Increased friction
- Poor maintenance
- Improper installation
- Shaft misalignment
- Wrong assembly length
- Dust and debris
Question 6: Can you reuse a mechanical seal?
Yes, a mechanical seal can be reused. However, it must be checked by a competent person. After it has made sure it is good to use, it can be reassembled and reinstalled as per the manufacturers' instructions.
