The 2XZ rotary vane vacuum pump has excellent performance, which can prevent the pump oil from flowing back after the pump is stopped and contaminate the pumped container and pipeline. The oil tank is treated as a compartment, and an oil and gas separation device is arranged on the exhaust port, which does not spray oil and reduces oil mist pollution. The motor is made of aluminum alloy and has high heat dissipation efficiency. The motor and pump are integrated. Use anti-vibration rubber feet to reduce vibration noise. Although the advantages are outstanding, it is inevitable that some small faults will occur. For these problems, let's talk about the elimination of common faults.
First, 2XZ rotary vane vacuum pump limit vacuum is not high and its elimination 1. The oil level is too low, there is a large exhaust sound, you can add clean vacuum pump oil. The oil is contaminated by condensable steam, which can be cleaned or replaced with new oil. The oil hole of the oil inlet nozzle is blocked, and the oil inlet nozzle can be dialed out to clear the oil hole.
2, 2XZ rotary vane vacuum pump external pipe, container, test instrument pipeline, joints and other air leaks. When there is a large leak, there is a large exhaust sound, and the exhaust port has a gas discharge, and the leaking portion should be found and eliminated. The rubber seal diagram of the inlet nozzle or gas ballast valve is improperly assembled, damaged or aged, and should be adjusted or replaced.
3. The vacuum system is seriously polluted, including containers and pipes, and should be cleaned.
4. The rotary vane, pump body or pump cover is worn out. If the clearance is too large, it should be inspected, trimmed or exchanged. The rotor spring is broken and should be replaced.
5. If the temperature of the pump is too high, ventilation and cooling should be improved. If the temperature of the pumped gas is too high, it should be cooled before entering the pump.
Second, 2XZ rotary vane vacuum pump injection oil level is too high, you can enter the excess oil. There is pump oil or debris in the mist eliminator and should be removed.
3, 2XZ rotary vane vacuum pump oil leakage 1, oil drain screw plug, oil tank gasket or improper assembly, screw tightening; oil standard is not tightened, plexiglass overheat deformation.
2. The connection between the pump body parts and the support 挚 the gasket is not well padded; the oil package is improperly fitted or worn; it should be adjusted or replaced.
4. 2XZ rotary vane vacuum pump noise 1. The rotary vane spring is broken and the spring can be changed.
2, there are burrs, dirt or deformation, running obstacles, should be checked for grinding and cleaning. The bearing is worn and the parts are worn. It should be trimmed or replaced.
3, the motor is out of order, should be checked.
5, 2XZ rotary vane vacuum pump returning oil 1, the check valve is not closed, after stopping the pump, the oil level will drop quickly, can be opened again and then stopped, observe the change or open the inspection.
2. The oil package in the two pump covers is improperly fitted or worn and can be exchanged. The pump cover or pump body is not flat and can be trimmed.
3. The exhaust valve is damaged and should be exchanged.
