Mini Lab Rotary Vane Vacuum Pump System Anti Corrosion

Rotary Vane Vacuum Pump Application

1. Whit the inlet port widely opened to atmosphere the pump is not allowed to work more than one minute.

2. The pump is not suitable for pumping over-oxidized, poison, explosive and corrosive gas as well as gases which react chemically with the pump oil contain particles of dust.

3. The pump is one of the basic equipment to exhaust a sealed vessel. It can be used either independently as main and can also be served as for pump for booster pump diffusion pump and molecular pump or as holding pump for a vacuum system and as a pre-pumping for different kinds of the pumps.

4. The pump is allowed to work continuously for many hours at a stretch under atmospheric temperature of 5℃-40℃ and intake pressure below 1230pa.While the pumped gas containing moisture of a relative humidity of more than 90% gas-ballast valve should be open.

Rotary Vane Vacuum Pump Specification

Rotary Vane Vacuum Pump Operating procedure

1. The pump should be erected on a dry airy and clean place.

2. The pump, with a handle at top and with four rubber pillarets at footings, is of portable type .Therefore in most case the pump is merely placed at a flat and stable surface.

3. To wire the motor, note the direction of rotation viewing from the fan end of the motor, the rotation should be clockwise.

4. The diameter of the pipe, which joints the vessel to be exhausted and the pump, should not be smaller than that of the inlet port of the pump. The pipe should be short and should have as few bends as possible in order to reduce the loss of pumping

speed. Meantime leakage of the pipe should be noticed .If rubber pipe is adopted, the pipe should preferably be desulfurized.

5. When the pump is started with the inlet port widely opened to atmosphere, little amount of oil mist will be brought out. It might affect the working environment, use plastic pipe to lead it away to open air.

6. The pump is equipped with such device which can prevent suck-duck of oil when it is stopped. Therefore it is not necessary to mount a magnetic operated valve on the inlet port.
