First, the X-type rotary vane vacuum pump features and uses: X series single-stage rotary vane vacuum pump is the first to remove a large number of water vapor new products, due to the pump itself with oil regeneration device and reliable gas-town device, Extended pump life. The basic equipment used to evacuate gas from a hermetically sealed container for use in electronics manufacturing, vacuum drying, filtration, dipping, coating, welding, smelting and laboratory equipment. Features: 1, Compared with the XD series single-stage vacuum pump has a high vacuum limit, for the slide valve vacuum pump can be adjusted by noise reduction needle valve to control noise, due to its rotor eccentric mass is small, and the balance of the rotor, so the vibration is small. 2, X series rotary vane vacuum pump suction efficiency. 3, X series rotary vane vacuum pump gas town performance is good. X-Series rotary vane vacuum pumps have a specially designed gas ballast to fill the vent chamber with dry gas, greatly reducing the partial pressure of steam in the vent gas. When it is below the saturated vapor pressure at the pump temperature, the pump can be evacuated with air filling to avoid condensation in the pump. 4, X series rotary vane vacuum pump with temperature control water volume control valve. Pump work through the pump itself with the above adjustment of water pressure, pump temperature can be adjusted to 75oC ± 5oC, thereby increasing the discharge pump, but should not exceed the pump temperature 80oC (tank temperature measurement point). 5, X series rotary vane vacuum pump with water separator. It allows the accumulation of impurities and condensate in the pump oil to the bottom of the water separator, through the drain valve installed at the bottom of the pump. Second, the X-type rotary vane vacuum pump unboxing Installation: Carefully remove the X-type rotary vane vacuum pump body, spare parts and manuals and keep it for future use. Remove the filler, wipe the surface of the pump dust, dirt. According to the packing list count the number. X-type rotary vane vacuum pump installed in a clean environment, well-ventilated, well-lit room to meet the requirements of Article 4. According to the use of the pump should be installed in a certain margin of the site, in order to facilitate operation and maintenance. Pump dimensions see. X-type rotary vane vacuum pump can be placed on a solid flat ground, without special foundation, if necessary, can be fixed plus additional screws and solid foundation, ground screw size see. X-type rotary vane vacuum pump, such as close to the use of precision instruments, should consider increasing the shock device. The vacuum vessel or flange to be sucked by the vacuum vessel is connected with the X-type rotary vane vacuum pump. If the flange is connected, the rubber ring groove shall be provided on the flange, the form and the size are shown in Fig. 50. The diameter of the connected suction vessel is not Should be less than the diameter of the pump inlet, pipe should be short, the joint should be less, otherwise affect the pumping speed, pipe and fittings leakage should be small. The amount of gas pumped by the container should be adapted to the pumping speed of the pump. The pumping speed relationship of the X-type rotary vane vacuum pump is shown in FIG. 4. It is advisable to install a vacuum valve between the pump and the vessel to be evacuated in order to control the gas flow. For the pump and recommended to install a bleed valve (or solenoid valve) to stop the pump bleed, to prevent the return oil and easy to start. Connect the power supply according to the voltage indicated on the motor label and the wiring method, and it is recommended to adopt the safety device to avoid overloading. Make sure that the rotation direction of the motor should be in the same direction as the arrow on the pump. Remove the exhaust plug and install the exhaust hood, or remove the cover of the nozzle. X-type rotary vane vacuum pump to be connected to the water source. Such as the pump must be pumped to remove toxic and corrosive ferrous metals gas, the vacuum oil from the chemical changes of gas, and more than room temperature and dust gas, the intake pipe should be installed in the neutralization, cooling, filtration and other related Device with the use, otherwise it will affect the X-type rotary vane vacuum pump performance and life expectancy. Remove harmful gases, should be placed on the appropriate pipeline, the exhaust gas to the outdoor away from the work area for processing. Note: The installation should be careful to prevent the iron, dirt, dust and other fall into the pump three, X-type rotary vane vacuum pump instructions: 1, X-rotary vane pump operation Note: (1) intermittent start 1-2 times, observe whether there is abnormal noise in operation and special vibration, no problem can be run continuously. (2) Note that the oil surface should be between the two oil sight lines of the sight glass. If the oil quantity is too high, it will cause difficulty in starting, returning oil and injecting oil, otherwise it will affect the degree of vacuum. Fuel shortage should be refueling hole refueling. Pay attention to stop the pump oil level to decline, the pump continuous operation a few revolutions, the oil will rise. (3) Open the cooling water (4) Open the valve on the pump intake nozzle, the size of the opening as the case may be. 2, For the first time installed X-type rotary vane vacuum pump, should do a test run first, when the pump should be installed without proper vibration and no special impact sound, the motor should not be overloaded, the oil temperature and ultimate vacuum should be consistent with technology specification. 3, stop X-type rotary vane vacuum pump should first shut off the valve on the inlet nozzle, with a deflation valve on the pump deflated, then cut off the power supply, and then stop water. 4, X-type rotary vane vacuum pump Notes: (1) Always pay attention to the oil level. (2) Open the valve slowly after starting the pump. (3) often pay attention to whether the normal pump operation, with or without special sound, the motor is overloaded operation. (4) Note that the cooling water is interrupted. (5) Note that the temperature rise of the pump does not exceed 40 ℃ (6) After the X-type rotary vane vacuum pump is stopped, the temperature of the rotary vane vacuum pump should be kept below 5 ℃.
