The main features of the Roots blower Roots blower biggest feature is the use when the pressure changes within the range allowed to regulate the flow of coal washing blower little pressure, a wide, has forced gas transmission characteristics. When the transmission medium is not oil. Simple structure, easy maintenance, long life, low vibration machine. Vacuum pumps. Because of the periodic suction, exhaust and compression caused by fluctuating instantaneous isometric flow velocity and pressure, and thus will have a greater aerodynamic noise. Also send mine oxygen Roots blower, the gap between the rotor and the rotor and between the cylinders can cause gas leaks, thereby reducing efficiency. Roots blower displacement is 0.15 to 150 m3 / min, the rotational speed of 150 to 3000 r / min. Single-stage pressure ratio is typically less than 1.7, up 2.1 food packaging vacuum blower, you can use multi-level series. Clover Roots blower with high-quality, high life, high efficiency, it is small, light weight, traffic, low noise, smooth operation, reasonable structure, is a new energy saving products and meet the IS09001: 2008 quality system standards request, by the power, building materials, chemical, textile, food, metallurgy, aquaculture, vacuum packaging, mining, pneumatic conveying systems, air separation industries and sewage treatment industries trust and recognition. Mine carries oxygen Roots blower, blower, Zhucheng East Han Machinery Co., Ltd. is provided by Zhucheng East Han Machinery Co. Zhucheng East Han Machinery Co., Ltd. (www.dhlcfj.com) (www.dhlcfj.com) strong, credible, Shandong Weifang fan, ventilation equipment industry has accumulated a large number of loyal customers.
