Huangshan dry screw vacuum pump secondary tertiary roots vacuum pump 02 Zhongni GP dry vacuum pump customized dry screw vacuum pump is mainly used in high-purity vacuum process, and can reach extremely high vacuum degree; it is especially suitable for chemical, biomedicine, electronics and other industrial fields. Compared to other types of dry pumps, dry screw vacuum pumps have higher efficiency and lower energy consumption. 02 Performance characteristics 1. Corrosion resistance design The surface of the parts in contact with the gas (cylinder inner surface and rotor surface) is nickel plated, and Teflon material PFA or PTFE coating can be used to avoid gas corrosion on the compression cavity parts, and is suitable for sucking toxic, corrosive and condensing gases. 2. the oil-free and water-free purification system runs a pure working process without oil and water, which is very easy to recover chemical gas media. 3、Low noise system mechanical design, no contact between metal and component interface during operation, to ensure long system life, low vibration, low noise and low wear. 4. Low exhaust temperature - rotor cooling system with water jacket, reinforced cooling from the inside in the compression zone, with this method, the gas temperature can reach below 150℃. 5. single stage twin screw - no need for intermediate cooling, easy solid impurity discharge system. 6. short air circuit -02 can make the compressed gas discharge quickly, so as to effectively avoid gas condensation and condensation corrosion of the machine cavity. 7、Compact all-in-one unit, small footprint. 8. low vacuum and high flow dry screw vacuum pump can ensure that the vacuum limit pressure reaches 0.05mbar, can operate continuously under any pressure, and the screw rotor has extremely high working efficiency. 9. Adopt high-precision mechanical seals to prevent process gas leakage. 10 It can be cleaned with inert gas, steam, and solvents, which is convenient for maintenance. 02 Typical application processes Low final pressure and long continuous operation make the pump suitable for use in the following fields: thinner (solvent) recovery, vacuum drying treatment, vacuum degassing treatment, continuous distillation in production, evaporation coating, continuous sterilization or intermittent sterilization, vacuum packaging, raw material addition and coating processing processes, etc. Dry screw vacuum screw 02
