Compared with the oil pump, the oil-free vacuum pump has low vacuum and small pumping capacity, but is compact in size, easy to install, simple to maintain, easy to move, does not produce soot, and does not pollute the environment, especially in laboratories with higher requirements. It is also one of the most frequently equipped equipment in the laboratory.
Therefore, when purchasing an oil-free vacuum oil pump, it is necessary to first determine the degree of vacuum required to work. If the demand is high, the vacuum pump selected should be higher than the required vacuum. Otherwise, the vacuum requirement will not be reached. Not working requirements. The second is the pumping rate of the oil-free vacuum pump, which is slightly larger than the required pumping rate during the selection, so that it can better meet the needs. Finally, see if the extracted gas is corrosive, corrosive gas will corrode the pump, and special materials must be used to meet the demand.roots-vacuum-pump-manufacturing
