Roots vacuum Main features: 1, in a wide pressure range (1 ~ 1 × 10 4pa) have relatively the pumping speed. 2, oil-free pump chamber Hebei Roots vacuum outlets, avoiding oil vapor contamination vacuum system. 3, small vibration, low noise. 4, a small mechanical friction loss, so the drive power is small. 5, easy to maintain and repair, low cost production and wholesale Hebei Roots vacuum pumps, high life. Advantages Roots vacuum pump inlet pressure is lower still has a large Roots vacuum pumping speed, but can not be used alone Hebei Roots Roots vacuum pump uses must be supporting the use of pre-stage vacuum pump. When the current stage vacuum pump system pressure pumped Roots vacuum pressure allowed to start before start Roots vacuum pump. Depending on the operating pressure and process conditions, pre-stage Roots vacuum pump can be mechanical seal pumps, liquid ring vacuum pumps, reciprocating pumps and so on. Different types of pre-configured Houluo Ci vacuum pump can achieve the ultimate pressure is different.
