 2X-type vacuum pump use and use of 

 2X-type vacuum pump for the two-level structure, and its performance from the high pressure stage and low pressure stage components, it is with the vacuum suction device or vacuum container, the container in running a large number of gas inhalation and discharged. When the equipment to obtain vacuum, high-level chip will be closed exhaust valve, high pressure level and the gas will be transferred to the second level, and by the second stage suction and discharge, vacuum equipment available so that a certain vacuum. The technical parameters of the pump 6 × 10-2pa. The use of the user, can be equipped with a vacuum booster pump, the pump before the pump as, due to the booster pump suction force to enhance, before the pump continuous extraction can make your device a higher vacuum. The pump is suitable for metallurgy, chemical industry, electric light vacuum, vacuum coating, food packaging, pharmaceutical, plastic, electronics, dry areas of use. 


 l, 2X-type vacuum pump is pumping gas one of the basic equipment, it can be used alone or with booster pumps, diffusion pumps, molecular pumps connected as a former high vacuum pump to use, widely used in electronic devices manufacturing, vacuum drying, filtration, impregnation, coating, welding, smelting and laboratory equipment. 
 2,2 X-type vacuum pump in the temperature range 5 ℃ ~ 40 ℃, the inlet pressure less than 10 under the conditions of care, allow long-term operation, has been pumping gas relative humidity above 90%, should the gas ballast valve. 
 3,2 X-type vacuum pump inlet through the atmosphere continuously operating spacious shall not exceed 3 minutes. 
 4,2 X-type vacuum pump is not used for pumping corrosive to metal, to pump oil from a chemical reaction, the gas containing dust particles, and high oxygen, explosive, poisonous gas. 



 Operating instructions 
 1, see the oil level. Oil level should be marked in the center of the oil, the oil level is too low, the exhaust valve can not be sealed, the vacuum effect; the oil level is too high will cause the fuel injection start time. Operation before the first belt off, turn the motor adjustment, and then start to avoid injection. Operation, the oil level increased slightly, is a normal phenomenon. Insufficient fuel, the use of vacuum pump oil No. l, from the filling hole to join. Oil to be filtered, to avoid debris into the plug hole. 
 2,2 X-type vacuum pump connection port solenoid valve if fitted, should be action with the pumps. 
 3,2 X-type vacuum pump began to start, should be to move the start button once or twice, so that the hydraulic pump chamber to the fuel tank, and then officially start operation. 
 4, the ambient temperature is high, the oil temperature increases, viscosity decreases, saturated steam increases, the vacuum will cause the limit down, ventilation should be strengthened. 
 5, check the limits of the vacuum pump should be used compression mercury vacuum gauge. Gauge port should be directly connected to the pump, running 30 minutes to reach ultimate vacuum. 
 6,2 X-type vacuum pump shut off before the suction port at the valve, and vacuum system isolation, and then stop the pump. 
 7, with a gas valve in the suction pump as the gas contains more condensable vapor, to open air
