First, the introduction of 2XZ rotary vane vacuum pump: 2XZ rotary vane vacuum pump is a two-stage high-speed direct-coupled rotary vane vacuum pump. It is eccentric in the pump chamber rotor, rotor slot and the rotor. When the rotor drives the rotary vane to rotate, the vane is closely attached to the cavity wall to separate the inlet and exhaust ports, and the intake cavity volume is cyclically expanded and inhaled while the exhaust cavity volume is periodically reduced Compress the gas and push the exhaust valve off to get the vacuum. 2XZ rotary vane vacuum pump equipped with gas-operated valve, with extended pump oil usage time and prevent pump oil mixed water role. 2XZ rotary vane vacuum pump with small size, light weight, low noise, easy to start and so on. In addition, there are measures to prevent back to oil (2XZ-8) and no measures to prevent oil spill contaminated sites. 1,2XZ rotary vane vacuum pump is the basic equipment to obtain vacuum, it can be used alone, can also be used as a variety of high-vacuum system before the pump and pre-pump. 2, the pump inlet continuous open air operation, not more than three minutes. 3, the pump does not apply to the removal of the metal corrosive, the pump oil from the chemical reaction, the gas containing particles of dust to the body oxygen content is too high, there is explosive gas. 4, the pump has to be used for compression pump or pump. 5, the pump working environment: temperature 5 ℃ -40 ℃ range, the relative temperature is not more than 90%, the inlet pressure is less than 1333Pa conditions allow long-term continuous operation. 6, when connected to the power supply, according to the provisions of the motor label wiring, should pay attention to the direction of rotation of the motor and the bearing on the direction of the arrow. 7, continuously being pumped containers, the diameter of not less than the diameter of the pump inlet, and the pipe should be short and less elbow, while paying attention to the pipeline leakage. 8, before each start to focus on the oil level to stop pumping oil to the oil glass diameter of 4/5 height is appropriate. 9, with a clean pump SY1634-70 No. 1 vacuum pump oil. 10,2 XZ rotary vane vacuum pump in the atmosphere or any vacuum under a start. XZ-1 single-stage pump If the start-up difficulties, you can dial the intake manifold plug start, and then put into operation. Second, 2XZ rotary vane vacuum pump failure and its elimination method: 1, 2XZ rotary vane vacuum pump is not high and the ultimate vacuum to eliminate (1) the oil level is too low, there is a large exhaust sound, you can add a clean vacuum pump oil. (2) The pump oil is contaminated by the condensable steam, which can be purged or replaced with fresh oil. (3) 2XZ-type rotary vane vacuum pump external pipes, containers, test instrumentation pipes, joints and other leaks. Big leak, there is a large exhaust sound, exhaust vent vent, should find the leak site, to eliminate. (4) inlet nozzle or gas ballast rubber seal improper assembly, damage or aging, should be adjusted or replaced. (5) 2XZ-type rotary vane vacuum pump into the oil hole blocked, can be set aside into the oil nozzle, clear the hole. (6) serious pollution of the vacuum system, including containers, pipes, etc., should be cleaned. (7) 2XZ-type rotary vane vacuum coil spring break, should be replaced. (8) Rotor, pump body or pump wear, the gap is too large, should be checked, trimmed or replaced. (9) pump temperature is too high, should improve ventilation and cooling. If the pumping gas temperature is too high, it should be cooled before entering the pump. 2,2XZ-type rotary vane vacuum pump fuel injection (1) the oil level is too high, can enter excess oil. (2) there is pump oil or debris in the mist eliminator, should be removed. 3,2XZ rotary vane vacuum pump oil leakage (1) oil drain plug, gasket gasket or improper assembly, screw tightening; (2) oil tighten, plexiglass overheating deformation; (3) 2XZ rotary vane vacuum pump Body parts and bearings are not good pad connection gasket; Improper or worn oil seal assembly; Should be adjusted or replaced. 4,2 XZ rotary vane vacuum pump noise (1) spin-leaf spring break, can change the spring. (2) glitches, dirt or deformation, the operation of obstacles, should check the grinding cleaning. (3) bearing wear, wear parts. Should be trimmed or replaced. (4) motor problems, should be checked. 5,2 XZ rotary vane vacuum pump back to oil (1) check valve is not closed, stop the pump, the oil level dropped quickly, and then re-open to observe changes or open inspection. (2) Two pump cover oil seal improper assembly or wear, can be exchanged. (3) pump cover or pump flat surface, can be trimmed. (4) exhaust valve damage, should be replaced. Note: Check the pump ultimate vacuum to compression mercury vacuum gauge shall prevail. Third, 2XZ-type rotary vane vacuum pump Note: solemnly declare: violation of the above provisions of the operation and use of the resulting personal injury and property losses, the Company shall not be responsible. Direct-coupled vacuum pump is strictly prohibited pumping out flammable, explosive and toxic gases; Direct-coupled vacuum pump can not be extracted from the metal corrosive and can react with pump oil gas; Direct-coupled vacuum pump can not be removed with the particulate dust And a large number of water vapor of gas; was pumping gas temperature not exceeding 80 ℃, the use of ambient temperature in order to -5 ℃ -60 ℃; direct-coupled vacuum pump shall not be used for compression pump and pump; ; When the pump is running, it is forbidden to block the exhaust port; ①The direct-connected vacuum pump uses the voltage of 192-248V, the 50Hz socket must be grounded; ② When unplugging the power, be sure to hold the plug and do not catch the power cord; ③ Direct-connected vacuum pump Do not place heavy objects on the power cord, do not let the power cord be squeezed; ④ direct-coupled vacuum pump do not use broken plugs and sockets; ⑤ direct-coupled vacuum pump do not use wet hands Power plug; ⑥ Direct-connected vacuum pump in a gas leak place do not plug the power plug and press the switch.
