Vacuum pump four characteristics
With the rapid development of vacuum industry, the application of vacuum pump is more and more widely, can adapt to a variety of environments for use. Vacuum pump equipment itself is also numerous advantages, many people do not understand its specific characteristics, in fact generally summed up in the following points:
(1) vacuum pump (liquid ring vacuum pump, screw vacuum pump, water jet vacuum pump) — large pumping speed in a wide pressure range
(2) vacuum pump (liquid ring vacuum pump, screw vacuum pump, water jet vacuum pump) — the rotor has good geometric symmetry, small vibration, smooth operation. There is a gap between the rotor and the rotor and the shell, without lubrication, friction loss is small, can greatly reduce the driving power, thus can achieve a higher speed
(3) vacuum pump (liquid ring vacuum pump, screw vacuum pump, water jet vacuum pump) — there is no need for oil sealing and lubrication in the vacuum pump chamber, which can reduce the pollution of oil vapor to the vacuum system
(4) vacuum pump (liquid ring vacuum pump, screw vacuum pump, water jet vacuum pump) — the rotor surface is a curved cylinder with complicated shape, which is difficult to process and check
Liquid ring vacuum pump and roots vacuum pump which suction?
Liquid ring vacuum pump, can be simply understood as vacuum, compressor
Roots vacuum pump, can be understood as a booster pump, increase the pressure.
The two are not in the same breath. But it can be combined with a liquid ring roots unit to maximize pressurization and increase suction.
