The Compressor Seals With A Polymer Composite
May 17, 2017

Compressor Seals as a general machinery, since its inception has been widely used in petroleum, chemical, natural gas, gas separation and other industries. At present, the commonly used compressor models are piston compressors, screw compressors, scroll compressors, centrifugal compressors and so on.

Piston type compressor (crankshaft connecting rod type) has the advantages of simple structure, mature technology, low technical requirement of processing and manufacturing, easy compression ratio and so on, Compressor Seals and has the dominant position in the compressor market.

Valve, packing, piston, cylinder and other seals in a variety of harsh conditions more and more become the focus of piston compressor design and manufacturing. In recent years, new materials have become a major direction in the study of piston Compressor Seals performance.

Here we come to understand the current mainstream sealing material

status quo

Piston Compressor Seals performance is an important indicator of the compressor unit, a direct impact on the exhaust pressure, displacement and other important parameters, the user's actual production and production efficiency plays a qualitative role. The sealing point of this type is mainly distributed in key parts such as packing, piston ring and valve. Due to the complicated working conditions (working seal), poor working environment (high temperature, high pressure and oil pollution), the high temperature and anti- Made clear and strict requirements.

At present, the piston Compressor Seals ring with polymer composite materials are mainly divided into polytetrafluoroethylene (PTFE) and polyether ether ketone (PEEK).
