Roots vacuum pump features: Start fast, low power consumption, low cost of operation and maintenance of Henan Roots vacuum supply prices, pumping speed, high efficiency, and insensitive to be pumping gas contained a small amount of water vapor and dust in 100 ~ 1 Pa pressure range greater pumping rate can quickly rule out a sudden release of gas. This happens in a pressure range between mechanical pump seals and diffusion pump. So Henan Roots vacuum outlets, it is often in series between the diffusion pump and mechanical seal pumps, used to increase the range of the intermediate pressure exhaust volume. At this time it is called mechanical booster. BZJ series two-stage Roots pump main features: 1, no oil and water pumping chamber, no secondary pollution; 2, with two single-stage Roots vacuum pump series offer compared to Henan, compact, small footprint; 3, fewer parts, easy maintenance and repair, reduces the cost; 4, the internal connection between the high and low vacuum chamber Roots vacuum, reducing the amount of leakage between the two pumps connected to the pipeline, improve the performance of the unit; 5, inside optimize the structure and improve the efficiency of the vacuum pump, reducing power consumption; 6, the control system of the entire unit is more simple and convenient; 7, reducing the unit auxiliary fittings, more conducive to the production crew and maintenance Henan Roots vacuum use, Roots vacuum pump Zhucheng East Han Machinery Co., Ltd. is provided by the East Han Machinery Co., Ltd. Zhucheng. Zhucheng East Han Machinery Co., Ltd. (www.dhlcfj.com) strong, credible, Shandong Weifang fan, ventilation equipment industry has accumulated a large number of loyal customers.
