2X Two Stage Rotary Vane Vacuum Pumps

2X Series rotary vane vacuum pump. its structure is equipped to use eccentric rotor and the stator chamber pot sliding in the rotor by spring tension and separatist wall close to the two stator vane. stator will be divided into two working chamber, rotary vane while expanding capacity to gas inhalation, while another volume continued to narrow. compressed gas from the valve to reach the atmospheric pressure above the second repeat operations every turn. 2X - for the two-stage rotary vane vacuum pump structure, when inhaled at high pressure, while the exhaust cavity ranks, inhaled at low pressure gas from entering the High suction mouth cavity, compressed into the lower airway through the wall cavity, compressed again, from low-level discharge valve. When the town pump with a gas valve, which contains a small amount of water vapor may allow extraction of steam condensable gases. 2X-2A,4A,8A,8,15 pump eccentric structure from top to bottom. ranks connecting the rotating rotor using convex form. 2X-30A,70A pump eccentric side of the structure, the lower rotor sets in the form of senior rotor axis of rotation, shell links using cooling water pump, cooling pump with a low temperature, low pressure characteristics of the total limit.
