4. Operation
4.1 Caution on Operation
WARNING
Never run the Vacuum pump on blocking up the exhaust outlet,
putting any device that hampers the gas passage. There is a risk that
pressure in the pump rises, and the main body of the pump and the
oil level gauge might explode, or the motor become an overload.
This product is not made as the withstand pressure structure.
Ensured pressure value of the Pump shall be 0.03MPa (0.3kgf/cm2)
(Gauge pressure).
If any valve was put to a pipe after the Exhaust outlet, check and
ensure that it is open.
CAUTION
Ensure to flow the cooling water during operation. Required Cooling
water shall be;
Cooling water volume:
PMB100D : air cooling
PMB300D : 2 L/min or more
PMB600D : 2 L/min or more
PMB1200D : 3 L/min or more
PMB2400D : 3 L/min or more
Cooling water temperature: 5°C ~ 30°C
Shortage of the cooling water might give damage on the bearing, gear
and shaft sealing, which results in contact of the rotor and casing and
operation stop.
CAUTION
Never fail to lubricate the machine.
If the lubrication oil came down lower than limit level during
operation, it might give damage on the bearing, gear and rod sealing
and result in leak, noise, motor overload and operation stop.
Never fail to conduct the lubrication oil out gassing before starting
operation when lubricated a new the Mechanical booster pump or left
it a long time after lubrication.
Starting operation without out gassing might generate a lot of
bubbles and cause them flow in the Rotor chamber.
CAUTION
Metal noise of high frequency might arise from the Mechanical seal
section during operation. That noise is indicating the oil shortage in
the Mechanical seal section.
In such a case, stop running the Pump and lubricate it following the
description of the “3.6.2 Lubrication to the Mechanical seal” and
restart operation after several minutes.
