The roots vacuum unit has the remarkable energy saving effect, the vacuum degree is high, the high vacuum interval extraction quantity is large, may be widely used in the power industry transformer, the power line cable, the capacitor vacuum impregnation, the vacuum drying process. Vacuum coating, vacuum smelting, vacuum heat treatment, vacuum oil filtration, freeze drying; Ideal vacuum equipment for air simulation test. If a small amount of water vapor or dust is sucked, a filter device should be added.
Roots vacuum unit can be used for deacidification of rice bran oil. It is flexible in installation, low in operating power and low in maintenance cost. The refined rice bran oil produced can meet the requirements of the national standard four-level refining rice bran oil, which is suitable for the small-scale physical refining production line.
Working principle of roots vacuum unit:
Roots vacuum pump is one of the biggest advantages in low inlet pressure has high extraction rate, but it cannot be used alone, there must be a front stage vacuum pump series, the pressure in the stay by the pumping system is the front-end of the roots vacuum pump vacuum pump allows the population pressure, roots vacuum pump to start work, and in the general case, roots vacuum pump is not allowed to work when high pressure difference, otherwise it will overload and overheating and damage, so using roots vacuum; The front stage vacuum pump must be chosen reasonably and the necessary protective equipment must be installed.
The former stage vacuum pump is usually oil seal mechanical pump, but if the limit pressure is not high, other types of crude vacuum pump can be used as the former stage pump. Especially in the extraction of a large amount of steam gas, the use of water ring vacuum pump as the front pump is very ideal, of course, the limit pressure can be reached less.
Scope of use:
Roots vacuum unit is suitable for sucking air and other non-condensable and non-corrosive gases.
Roots vacuum unit is widely used in need large pumping speed and required to obtain a variety of low and high vacuum in the vacuum system, such as: vacuum smelting, steel fluid degassing, the dynamic simulation test of vacuum to obtain a large space, power capacitor, transformer vacuum impregnation process, fluorescent tubes, light bulbs on the automatic production line of exhaust gas, thermal insulation inside edge exhaust, fore-sucking for vacuum coating equipment, in the process of magnesium reduction extraction, monocrystalline silicon degassing in the refining process and so on.
Roots pump in use process if the results in the decrease of vacuum degree, the need to check the essential point is whether there are any changes in the clearance between the roots pump rotor, if the rotor of roots pump clearance, you need to replace the roots pump, because this kind of roots pump is not in the process of production and processing of roots pump rotor do static and dynamic balance, or the collar seal.
