2XZ rotary vane vacuum pump disassembly steps are as follows: 2XZ rotary vane vacuum pump removal methods and installation steps, disassembly: 1. Drain the oil 2. Loosen the inlet Tsui flange screws, pull out Gas Tsui, loosen gas flange flange bolts, pull out the gas valve. 3. Remove the fuel tank. 4. Remove the check valve cotter and remove the check valve impeller. 5. Remove the bearing and pump connection screws, remove the pump parts, motor dismantling depending on convenience. 6. Loosen the cap screws, remove the pump cap, and pull out the two rotors and the rotors. When removing the lower rotor, he first removed the split pin. Second, 2XZ-type rotary vane vacuum pump assembly: 1. Wipe parts with gauze to prevent the plug wire plug back, it is best to use cleaning fluid and brush cleaning. 2. Rotor into the rotor slot, the rotor into the stator that is spring body, install L senior pump cover, pins, screws, keys, coupling, hand rotation, there should be no leakage and significant weight, Should be installed when the stator top down, to make the rotor close to the arcuate surface of the stator, the gap is best in 0.0lmm. Low-level rotor assembly method above. 4. Check valve impeller and other check-back parts, should make the check valve head plane aligned into the oil hole, according to the work of the rotation of the rotor and gently hands. The reverse blocking the impeller, the oil hole should be opened and closed when the valve head to adjust the maximum opening height of O.8 ~ 1.2 mm, the specific removable check valve seat, rubber check valve head position in the stem hole to achieve . Simple check: face the impeller so Φ3mm drive pin in the right hand horizontal position, turn the impeller clockwise, then the check valve head plane opening height is near the maximum should be 0.8 ~ 1.2mm. Rotor stop in any position, hands loose from the impeller, the check valve head should automatically fall off the oil hole. 5. Install 2XZ rotary vane vacuum pump valve, oil repellent plate and other parts. 6. The pump, keys, couplings, motors mounted on the support. 7. Install the fuel tank. 8. Insert the inlet nozzle, gas valve, fitted with flange fastening. Note: 1. Friction surface assembly clean vacuum pump oil. 2. Remember the original parts with parts, can reduce running time. 3. Fasteners should be loose. (Editor: Huang Nengwen QQ :)
