Seal in the application affected by what

We found out the problem that the repair team faced. When they switched to a newer and better oil, the seals began to leak. The oil in the cylinder was found to be contaminated with metal debris. Did you find a problem in the piston cylinder?

The costs associated with accidental spills are often enough to make you reevaluate certain elements of your job. Based on the information provided, the problem appears to be with the hydraulic system or the seals and piston cylinders of a large piston compressor. The answer to this question is that both of these problems, along with a host of other factors, can cause a seal to leak. In either case, a root cause analysis should be performed to determine the source of the problem.

In order to alleviate seal leakage problems and select the best solution, you must first consider the type of seal being used. There are four main types of seals: static seals (gaskets and o-rings), dynamic rotating contact seals (lip seals and mechanical face seals), dynamic rotating non-contact seals (labyrinth seals), and dynamic reciprocating contact seals (piston rings and piston seals) . Rod Packing) which are the types of seals discussed here.

The purpose of the seal is to prevent contaminants from entering while retaining lubricant. Dynamic reciprocating seals attempt to seal sliding metal surfaces. With each stroke, oil leaves the system and contaminants are drawn back in, so determining the cause of seal failure is often difficult, and even harder to fix.

Seals can be affected by many factors, including lubrication, temperature, pressure, shaft speed, and misalignment. Most conventional oil seals are designed for low pressure applications. The seals also need to be constantly lubricated with a high performance grease of the correct viscosity compatible with the seal material. The oil temperature and the ambient temperature should be evaluated as the temperature range cannot exceed the range of the sealing elastomer. In addition, shaft and bore misalignment can cause wear to be concentrated on one side of the seal. However, shaft speed is one of the most important factors in seal selection and determines all other factors.
