Air cooled roots vacuum pump
Because of its special structure design, air-cooled Roots vacuum pump can operate reliably for a long time under high pressure difference and high compression ratio. Cooling gas from both sides of the pump body into the pump suction chamber, so that the pump will not appear because of compressed gas overheating, but the pump pumping performance has no impact. The rotor rotates in the pump cavity and completes the process of suction and exhaust. Coolers and motors are necessary accessories for each pump. The specifications of coolers and motors are determined according to different operating conditions.
The working principle of the air cooled roots vacuum pump:
Gas circulating cooling Roots vacuum pump is mainly composed of rotor 1, rotor 2, pump 4, cooler 7 and so on. Because of its special structure design, it can operate reliably for a long time under high pressure difference and high compression ratio. Cooling gas from both sides of the pump body into the pump suction chamber, so that the pump will not appear because of compressed gas overheating, but the pump pumping performance has no impact. The rotor rotates in the pump cavity and completes the process of suction and exhaust. Coolers and motors are necessary accessories for each pump. The specifications of coolers and motors are determined according to different operating conditions. Pumps can be used alone or in series with more than one pump, or with liquid ring vacuum pump and ordinary Roots vacuum pump in series into a unit to achieve higher vacuum to meet various technical requirements.
The characteristics of the air cooled roots vacuum pump:
1. The scope of application is wider and wider.
Because the exhaust can withstand ultra-high pressure, so effectively and thoroughly solve the ordinary Roots vacuum pump due to excessive pressure difference, vacuum pump caused by the difference in the overload, overheating phenomenon.
2. Work at higher inlet pressure.
The air-cooled Roots vacuum pump can theoretically work under the condition of atmospheric pressure at the inlet, and the maximum pressure difference can be calculated according to the process conditions to determine the required motor power.
3. It can directly discharge the atmosphere without waste water discharge.
4. It can be connected to the roots pump set in series with the front pump.
Air-cooled Roots vacuum pump can work perfectly under high pressure difference, so it can reduce the front-stage pump to achieve energy saving and emission reduction effect, energy saving effect is more remarkable.
5. Easy maintenance and maintenance, low cost and high life.
General Roots vacuum pump is not easy to maintain, maintenance costs, and life is not high, air-cooled Roots vacuum pump completely solved this problem, easier to maintain and high life.
Gas-cooled Roots vacuum pumps can be widely used in any vacuum system requiring large and medium pumping speeds, such as vacuum coating, vacuum welding furnace, vacuum heat treatment furnace, large-scale space simulation test, lamp and bulb manufacturing, laser manufacturing, vacuum packaging equipment, automobile manufacturing, centralized vacuum pumping system, etc. Chemical processing, vacuum degassing, vacuum degassing, vacuum dehydration, vacuum freeze drying, vacuum distillation.
