In the process of using vacuum pump, we need to pay attention to many aspects. If used improperly, it will have a great impact on the whole vacuum system, and even bring great economic losses to the enterprise. According to many years of practical experience, the technical staff of our factory summarized the matters needing attention in the use of vacuum pump as follows, hoping to be helpful to everyone.
If there are condensable vapors or volatile liquids or corrosive gases in the pumped experimental system, vacuum pumps can not be used directly to pump the system. Condensers, gas washers or absorption bottles should be connected between the system and the intake pipe of the pump to remove the above gases.
A three-way piston is connected to the intake pipe of the pump.
Before the vacuum pump stops running, the intake port of the pump should be connected with the atmosphere through the three-way piston to prevent the pump oil from sucking back and polluting the experimental system.
