Note - when using anticorrosive vacuum pump

1, anticorrosive vacuum pump vibration on the process and the environment have influence? If you don't allow the process, should choose no vibration of the pump or vibration control measures.

2, understand to pumping gas composition. The gas does not contain condensable vapor, whether whether particles of dust and corrosive. When choosing anticorrosive vacuum pump, you need to know the gas composition and gas pumping by choosing appropriate pump. If the gas contained in the steam, particles and corrosive gas, should consider to install auxiliary equipment in the inlet pipe of pump, such as condenser and dust collector.

3, anticorrosive vacuum pump should be able to remove the vacuum equipment in the process of its work under the pressure of all gases.

4, anticorrosive vacuum pump has been assembled correctly. Because the anticorrosive vacuum pump has selective pumping function, so sometimes a pump cannot meet the pumping requirements, so you need to combine multiple pump to complement each other to meet the pumping requirements. For example, titanium sublimation heat pump pumping speed of hydrogen is very high, but it can't take helium, and three pole sputtering ion pump ( Or double was asymmetrical cathode sputtering ion pump) For argon has certain pumping speed, use a combination of these, the vacuum degree of vacuum unit will get better. In addition, some of the water ring vacuum pump can't work under atmospheric pressure, need to vacuum in advance. Some water ring vacuum pump outlet pressure below atmospheric pressure, and the need to pump before, so you need to combine.

5, anticorrosive vacuum pump equipment requirement for oil pollution. If equipment strict with oil free, should choose a variety of oil pump, such as water ring pump, molecular sieve adsorption pump, sputter ion pump, cryogenic pump, etc. If not strict, you can choose to have an oil pump, add some oil pollution prevention measures, such as adding cold trap, baffle, grease traps, etc. , can also meet the requirements of clean vacuum.

6, the correct selection of anticorrosive pump working point. Each pump has a certain working pressure range.

7, water ring vacuum pump in oil vapor how to affect the environment. If you don't allow pollution environment, you can choose oil-free water ring vacuum pumps, oil or steam exhaust to the outside.

( 1) Regularly check whether corrosion of the vacuum pump pipe and connector is loose. Turn the water ring vacuum pump with the hand, see whether the water ring vacuum pump flexible.

( 2) Bearing grease is added in the bearing body. Should observe the oil level in oil mark the center line, and shall promptly replace or add lubricant.

( 3) Unscrew the liquid ring vacuum pump body drain plug is filled with water ( Or mud) 。

( 4) Close the outlet pipe gate valve, outlet pressure gauge and inlet vacuum gauge.

( 5) Motor running, please try to see if normal rotating motor.

( 6) Start the motor. When the normal operation of water ring vacuum pump, open the outlet pressure gauge and the inlet water ring vacuum pump. After pressure display appropriate, gradually open the valve and check the motor load.

( 7) Try to anti-corrosion pump control the flow and head within the scope of the instructions on the label, to ensure that the water ring vacuum pump to run at top efficiency, to achieve energy saving effect.
