Anti-freezing measures for oil-free vacuum pump

Oil-free vacuum pump is a kind of mechanical vacuum pump that can operate without any oil as lubrication, which is composed of stator, rotor, rotary disc, cylinder body, motor and other main parts. Oil-free vacuum pump as a kind of mechanical equipment mainly composed of metal, so has most of the characteristics of metal, such as in the cold conditions will increase brittleness, easy to break, so in winter oil-free vacuum pump anti-freezing measures are essential.
Compared with the oil pump, the oil-free vacuum pump has low vacuum degree, small air volume, small size, easy to install, easy to maintain, easy to move, no smoke, no pollution of the environment, especially in the laboratory with higher requirements. The pump can be used for air conditioning, refrigeration equipment repair, medical equipment suction device, printing machinery, vacuum packaging, vacuum blister, physical and chemical experiments and need a vacuum environment for small devices and other vacuum operations. It can also be used as a small oil booster pump, oil diffusion pump, molecular pump and so on. However, the pump is not suitable for removing gases that are corrosive to ferrous metals, chemically reactive to pumping oil, containing particulate dust, and containing excessive oxygen and explosive toxic gases. Can not be used as a transport pump (i.e. pumping from one container to another).
The anti - freezing measures of oil - free vacuum pump are summarized by professional oil - free vacuum pump manufacturers.
After the oil-free vacuum pump is out of service in winter, we should release all the water stored in the pump and pipeline to avoid the water pipes or pump bodies from freezing and cracking after the temperature drops, and clean the external dirt and dust.
Place the pump at room temperature. Just below zero.
Apply a steel wire brush to clean the rust of cast iron parts such as the pump cavity and connecting parts of the oil-free vacuum pump, then apply anti-rust paint, and store in a ventilated and dry place after drying.
If the water pump freezes, use hot water or pour boiling water into the pump to internalize the ice. Or heat pump housing.
Adopt insulated oil-free vacuum pump. Add steam or hot water to the insulation. In case of ice.
In addition, can be added in the oil-free vacuum pump outside the tube heat exchanger, improve the temperature of the use environment and buy insulation equipment when the purchase to avoid the product freezing phenomenon, in addition to the daily use, but also to do a good job of cleaning.
