The use of pneumatic seals - Introduction
Pneumatics, which is one area of fluid technology, is the science of the behaviour of gases. The term pneumatics, which is derived from the Greek pneuma, is today mostly considered to be the transfer of energy by compressed air. Pneumatic drives and actuations, used to an increasing extent for the mechanisation and automation of production processes, are essentially constructed from valves and cylinders. The working of pneumatic equipment requires the sealing of volumes of air under pressure. Pneumatic seals are divided into cylinder seals and valve seals. The differentiated sub-division of valve seals, similar to the classification used for cylinder seals, would not be sensible. Valve seals are special seals which conform to the differing valve constructions of individual manufacturers.
Use of hydraulic seals
Different requirements and loads in numerous instances have led to the development of various types of seals. Hydraulic seals can be categorised according to their function and design Moreover, hydraulic seals are sub-divided into seals with a symmetrical cross-section and such with an asymmetrical cross-section. Asymmetrical seals are designed with interference on the entire axial width of the static diameter to achieve a firm seat in the groove. Therefore, the correct pre-load on the dynamic diameter is only reached after fitting into the housing
These Shaft Seals prevent the excessive wear and heat buildup at the shaft often caused by internal pressure.
- Economical seals are reliable at pressures up to 300 psi.
- Built with touch fluoroelastomer sealing element, strong metal case and large, pressure-activated PTFE anti-friction element.
- Can be used in a broad range of equipment, in rotary or reciprocating motion.
