Why do Mechanical Seals Fail?

Mechanical seals are usually included at the face of machines, inserted to protect and obstruct the exchange of gaseous substances, liquids. The major flaw in using this kind of seals is that they wear out easily and often leak.

Seals inserted within machines are generally are placed at the face or the opening where the machine comes in contact with various substances which come in contact. Generally the main purpose of the mechanical seals is to obstruct mixing of various substances. But often these seals wear out as they are subjected to constant abrasion and other extreme factors like temperature and pressure. Other major reason which makes the seals faulty and inappropriate for use is external factors like climatic changes and various others.

However as compared to the other varieties of seals available widely in the market these seals fail mostly due to the some of the common factors, which are enlisted below so if you are planning on choosing mechanical seals the elaboration below will offer insights about the flaws to keep in mind about mechanical seals, depending on the various kind of machines.

Generally, mechanical seals are placed on the faces of machines, which are stationery. So in this placement commonly the seals of this kind wear out due to thrust growth because of various elements within machines. Often the rise in temperature causes the seals to corrode and flaking appears which if not replaced can impact the productivity.

When placed in radial shafts or machines often mechanical seals dislodge and wear out. Also the other reason for the failure is the corrosion due to dripping lubrication from the bearings or due to abrasion against bearings. Often due to the vibrating movement of machines in which the seals are inserted, they imbalance due to constant motion. Often they start chipping, peeling and sometimes even the mechanical seals stretch, swell or clog and even the slide down after corrosion into the cavity of machines.
