Edwards EH4200 Roots pump repair, pump repair dry Edward QDP40

 By a pair of leaf cavity pump rotor synchronous, urging action to move the reverse rotation of the vacuum pump exhaust gas is achieved. Roots mechanical vacuum pump means having a pair of high-speed rotating rotor synchronous soles Edward GV250 dry pump maintenance, this pump is not pumping alone, the first stage to be equipped with seals, water ring may be straight rows atmosphere. Its structure and working principle similar to Roots blower, while working with its suction port is evacuated container or vacuum system main pumping phase. Between this vacuum pump rotor and the rotor, between the rotor and the casing do not touch, the gap is generally 0.1 to 0.8 mm; no oil lubrication. There arc line rotor profile, involute and cycloidal. Involute rotor pump high capacity utilization Edward GV160 dry pump maintenance, easy to guarantee precision Edwards EH4200 Roots pump repair, so multi-rotor profile involute. Roots vacuum pump speed can be up to 3450 ~ 4100 rev / min; pumping rate of 30 to 10,000 liters / sec (1 liter = 10-3 m 3); ultimate vacuum: Single-stage of 6.5 × 10-2 Pa, two-stage for 1 × 10-3 Pa. Roots vacuum pump Features 1.JZJ2B series Roots water ring vacuum unit uses energy-efficient water ring vacuum pump as before, so JZJ2B series Roots liquid ring vacuum unit than JZJ2S series Roots liquid ring vacuum unit has a high efficiency compact, no leakage (2BV series of mechanical seals standard design, unlike 2SK series of packing seal), corrosion (2BV series aluminum bronze impeller), the advantages of the high degree of protection. 2. Roots vacuum unit before the pump working fluid to use more water, may also have an organic solvent (available as methanol, ethanol, xylene, acetone and other organic solvents) or other liquid Edward, the former as a closed loop pump system , greatly reducing the pollution of the environment, while greatly improving the recycling of organic solvents. Its ultimate vacuum is determined by the saturation vapor pressure of the working fluid.
