DESCRIPTION OF FUNCTIONS
The air pressure is supplied to the reciprocating pump from the pressure tank 1 via a tube or
hose line
2 and a pressure control valve 3.
The air supply from the pressure tank to the reciprocating pump can be interrupted by the ball valve
4.
The ball valve
5 is used for manually releasing condensation (an automatic steam trap would be
preferable here).
The safety valve
6 protects the pressure tank against inadmissible rises in air pressure (e.g. in the
event of heating).
Since as a rule the air pressure supply
is not installed for the reciprocating pump and because it
is obligatory, the reciprocating pump is also provided with a safety valve
7.
During operation of the drive (air motor) of the reciprocating pump, the air pressure escapes into the
atmosphere via the silencer
8.This releases its pressure.
The fluid (coating or auxiliary agent) is sucked into the reciprocating pump from a container
9 via
the suction line
bl and supplied under pressure to the spray gun bo via the high-pressure screen
bm and pressure line (hose or pipe) bn.
A sieve (dirt trap)
bp protects the reciprocating pump against foreign bodies which have accidentally
entered the fluid.
A liquid unit (detergent unit)
bq is essential in reciprocating pumps of this design. The operating
position (attachment position) of the reciprocating pump will depend on it.
Since the appliances also use AIRLESS PLUS for spraying (air-boosted high-pressure spraying
equipment), it is recommended to attach a filter regulator
br at the air pressure branch.
EQUIPMENT COMPONENTS – IMPORTANT INFORMATION
The following components are required in an operational system:
THE RECIPROCATING PUMP
Functional description of the reciprocating pump; following part "Technical Description of
Product B.6.20.44-P".
AIR PRESSURE SUPPLY
The air pressure supply consists of the compressor, the pressure tank with steam trap,
possibly an air pressure drier and pipeline.
The air pressure supply is generally already available to the user.
- When air pressure supply needs to be installed, the relevant accident prevention
regulations, safety rules and user information must be observed, in particular the
information supplied by the manufacturer of the compressor.
