3.4 Exhaust port pipe
Connect the pump exhaust port and the duct pipe etc. with NW40.
In addition, this has no silencer function by default. In consideration of the work environment,
attach the silencer (a paid option) as necessary.
If the pipe diameter is small or any foreign substances adhere to the
inside of the pipe in wiring to the exhaust port side, the pump inner
pressure increases. As a result, the casing or the oil level gauge may
rupture, oil leak may occur, or the electric motor may be overloaded.
(1) For duct piping, be sure to use conducting materials (electricity
can be conducted). If a non conducting material is used, static
electricity occurs and static buildup may cause a spark when
exhaust gas passes, becoming a source of ignition.
(2) In the process where combustion or flammable gas flows, use
diluent gas. Supply the diluent gas from the intake port so that
the exhaust gas concentration is lower than the explosion limit.
(3) If the exhaust pipe is a thin metallic pipe, accordion, bellows, etc,
the pipe resonates with the exhaust pulse and the noise may
become higher than the work environment standard. Use pipes
with high pressure resistance.
