Edward vacuum pumps not only need to know the utility of the equipment before use, but also need to be clear about the instructions for the equipment, which will make us smoother. Operating in accordance with the instructions in the use of vacuum pumps will also allow users to protect the environment and safety. Sex has more attention.
- Equipment use requirements: Edward vacuum pumps are used to pump clean gases, but be careful not to pump toxic, flammable, explosive, corrosive gases or steam, chemicals, solvents and powders. Such as flammable gas, special or high-concentration strong acid and alkaline gas containing special chemical composition, or high-concentration gas in semiconductor process, organic solvent, crystallization gas, etc. These gases are easy to make the bearing invalid.
- Temperature requirements: The intake air temperature needs to be lower than 50 ° C, otherwise a cold trap needs to be added between the evacuated chamber and the pump inlet to reduce the temperature to below 50 ° C.
- When pumping a gas containing water vapor, open the gas ballast valve for pumping, and the water vapor content of the pumped gas is required to be below 23 g / day. If this limit is exceeded, the life of the gas ballast valve will be shortened.
- It is necessary to install a motor protection switch, and regularly check to make sure that the pump is safely grounded.
- Do not move the Edward vacuum pump by one or two people. This is handled, installed, configured, wired, operated, maintained and inspected by professionals, otherwise there will be a risk of electric shock, injury or damage to the pump or even the vacuum chamber.
- Do not continue to use the damaged pump, otherwise there will be danger of injury, electric shock or even damage to the pumping system.
- The exhaust pipe should be connected to the exhaust port to prevent dust from entering the pump.
- Do not touch the pump motor or metal parts when the pump is working or just stopped, if it really needs to be contacted, take corrective measures to prevent injury.
- Install a shut-off valve at the air inlet. After the vacuum pump stops, the vacuum degree at the air inlet decreases because the atmosphere at the air outlet returns to the air inlet, not the cause of the Edward vacuum pump. To ensure the vacuum degree in the vacuum chamber, a shut-off valve should be installed between the vacuum chamber and the pump.
- Be careful not to scratch the inlet and exhaust flanges to avoid damaging the flanges and causing the vacuum to go up.
The importance of the environment and the requirements for the use of Edward vacuum pumps are reflected in the equipment’s instructions for use. Proper operation will not only bring corresponding benefits but even make the equipment more effective.
