How to choose the type of vacuum pump
The vacuum pump is a rotary varactor vacuum pump to be used before the foreline pump can be used in a wide range of pressure has a larger pumping speed on the gas to be extracted gas is not sensitive to dust and water vapor is widely used Metallurgical, chemical, food, electronic coating and other industries. Mainly WLW series vertical oil-free vacuum pump model, W reciprocating vacuum pump model, 2X, 2XZ rotary vane vacuum pump model, ZJ, ZJH Roots vacuum pump (ZJH type for the patented vacuum pump products), 2SK, SK water Ring vacuum pump, 2BV, 2BA water ring vacuum pump, H, 2H slide valve vacuum pump, TLZ-type vacuum pump, SL Roots blower, JZJHX Roots rotary vane vacuum unit, JZJHS Roots water ring vacuum unit, JZJHWLW Type vertical oil-free vacuum unit, JZJP Roots water jet vacuum unit, JZJHBA Roots water ring vacuum unit, RPP-type water jet vacuum pump, JZJH2H Roots-spool valve vacuum unit and other vacuum pump models. 2BV water ring vacuum pump 2BV water ring vacuum pump working principle works: 1. First, you should fully understand the composition of gas being drawn. Such as gas containing non-condensable vapor, whether the particles of dust, whether corrosive, explosive and so on. If the gas contains vapors, particles, and corrosive gases, consideration should be given to installing auxiliary equipment such as condensers, dust catchers, etc. on the pump inlet piping. If the extraction of gas is also corrosive, you must use stainless steel. If the extracted gas is explosive, you should choose water ring vacuum pump and explosion-proof motor, because the water ring vacuum pump is the whole process isothermal. 2. Vacuum equipment or components of the oil pollution requirements. If the equipment is strictly required oil-free, should choose a variety of oil-free pumps, such as: water ring vacuum pump, molecular sieve adsorption pump, sputtering ion pump, cryogenic pump. If the requirements are not strict, you can choose to have a pump, and add some oil pollution control measures, such as adding cold trap, baffle, oil well, etc., but also to achieve clean vacuum requirements. 3 different types of vacuum pump oil discharged from the environment on how the impact. If the environment does not allow contamination, choose an oil-free vacuum pump such as a water ring vacuum pump or vent the vapor to the outside. 4. If more than one large water ring vacuum pump at the same time, the circulating fluid should be cooled, or affect the degree of vacuum. The cooling unit can be equipped with a cooling tower and pressurized booster pumps are required. 5. Vacuum pump working pressure should meet the ultimate vacuum vacuum equipment and work pressure requirements. Vacuum pump is usually selected to be higher than the degree of vacuum vacuum equipment vacuum to an order of magnitude. 6. Vacuum pump in its working pressure, should be able to drain away all the gas generated in the process of vacuum equipment. 7. Vacuum pump vibration generated during the process and the environment have no effect. If the environment is not allowed, should choose a vibration-free vacuum pump model or take shock measures.
