One, JZJX Roots rotary vane vacuum unit overview: JZJX Roots rotary vane vacuum unit is ZJP Roots pump to do the main pumping, single-stage or two-stage rotary vane pump as before the pump is low, high vacuum equipment, the entire unit mounted on a rack, with pipes, valves and electrical control box, in addition to a minimum of two specifications, compact unit comes with a cooling water pipe system, easy to use. When 2X-type rotary vane vacuum pump reaches constant pumping speed limit lowered, ZJP Roots pump allows crew to maintain a relatively large vacuum pumping speed at the limit. Roots rotary vane vacuum unit high vacuum, sustainable work and low noise. In order to improve the pumping performance Roots rotary vane vacuum unit, to achieve high ultimate vacuum and pumping speed characteristics improve before when low inlet pressure and large vacuum unit is equipped with a very small size pump, Roots rotary vane vacuum Unit also has three units from the secondary roots vacuum pump series. According to the size of the system is evacuated and gas state, on behalf of Roots pumping than the speed of rotary vane vacuum pump between each unit is generally between 4:1 to 10:1, the former suitable for large vacuum systems and long hours low inlet pressure or extreme working under vacuum conditions. JZJX Roots rotary vane vacuum unit in order to prevent the front-stage rotary vane vacuum pump oil back down, a solenoid valve on the first stage pipeline, usually with DDC series of electromagnetic vacuum solenoid valve or DYC series vacuum pressure valve for the front-stage rotary vane vacuum pump motor linkage. Second, the use JZJX Roots rotary vane vacuum unit: JZJX Roots rotary vane vacuum unit suitable for pumping air and other no-condensable, non-corrosive gases, widely used require large pumping speed and the need to obtain low and high vacuum of various vacuum systems. For example: vacuum smelting, steel liquid degassing, vacuum sintering, a large space simulation of dynamic vacuum acquisition, power capacitors, transformers, vacuum impregnation treatment, fluorescent tubes, exhaust bulb automatic production lines, continuous discharge of Vacuum Flask vacuum coating equipment in the pre-pumping, pumping magnesium reduction process, silicon refining process, degassing and so on.
