Omega Air pressure vessels
TPV, TPH
Storing of compressed air
The size of the pressure vessel is defi ned
according to the quantity of the
supplied air from the
compressor on
which is connected, control system and
consumption of compressed air.
Storing of compressed air
Compressed air produced by a
compressor is stored in a pressurized
container. Needs for the compressed air can be covered
without the
compressor operating. In the meantime, it is
in standby mode and does not consume electricity.
Pressure vessel capacity covers momentarily and peak consumptions
of compressed air. Thatswhy compressed air motor
is not put in operating so often, which results in lower
operating costs.
Pulsating supply of compressed air
Due to its way of operation, the piston
compressors are
causing pulsating volume fl ow of compressed air. This
mode of operation harms the diff erent devices that are
connected to such system. For example, in particular the
process control and measuring equipment at such a course
are not working properly. Pressure vessel regulates this
fl uctuations and calms it. There are no such problems in
screw
compressors application, because there is a constant
supply of compressed air.
The collection of condensate
Compression leads to condensation of water in the air. This
water usually enters with a stream of air in the pressure
vessel, where the heat, which was introduced into the
system at compression, is passing to the surrounding area.
Cooling of the pressure vessel results in the large amounts of
condensate which generates on its walls. Condensate is collected at the
bottom of the container, where it has to be drained out of the system.
Pressure vessels, which are drained irregular, are subject to corrosion caused
by condensate. The rust protection can be galvanic or with epoxy coating.
Final inspection and puting into the service
Pressure vessels are loaded from internal pressure, so they are dangerous for its
operation. Their manufacture, testing, installation and operation must be carried
out in accordance with the Pressure equipment directive. The content of the directive
changes, so it is necessary to constantly follow the content. Documentation
of Pressure Vessels should be carefully kept. Pressure vessel must always bear the
inscription plate with the content required by the PED 97/23.
