The oil mist filter is used in the exhaust port of the vacuum pump to capture and filter the oil mist discharged by the vacuum pump to prevent the oil mist from polluting the air. Especially in the use of gas or large extraction flux. At the same time, the oil captured in the oil mist filter can be returned to the vacuum pump, of course, we should ensure that the gas is not contaminated pump and pump oil.
The performance characteristics of
● prevent oil spray to meet health and safety requirements.
● use the oil return assembly to return the oil from the oil mist filter to the pump to reduce pump oil consumption.
● when the oil filter element is blocked, the internal safety valve opens automatically.
Oil return assembly: the filtered oil in the oil mist filter can be returned to the vacuum pump to reduce pump consumption. For example, the gas retarder assembly can be installed on the vacuum pump with the gas retarder.
Double-stage vacuum pump mechanical selection
The vibration of the vacuum pump during the operation of the process and the environment has no impact. If the process is not allowed, should choose no vibration of the pump or take anti-vibration measures.
Know the composition of the gas being pumped, the gas does not contain condensable vapor, there is no particle dust, there is no corrosive, etc. When choosing the vacuum pump, you need to know the gas composition and select the corresponding pump for the pumped gas. If gas containing particle, and corrosive gas and vapor, should be considered in the pump inlet piping installation of auxiliary equipment, such as condenser, filter, etc.
The vacuum pump in its working pressure, should be able to discharge all the gas produced in the process of vacuum equipment.
