A common classification and characteristics of vacuum unit

full vacuum system software is made up of vacuum pump and vacuum unit and its various pipes, precision measuring equipment, gate valves, electrical equipment automatic control system and a series of supporting facilities of auxiliary components together. Screw vacuum pump manufacturers are easy to introduce in the common vacuum unit classification and its main purpose.

vacuum unit generally named according to the types of the main valve, can then be based on features of goods in order to develop the category, such as the oil content of vacuum units with no oil vacuum units; More generally, by the vacuum to use category, can be divided into low vacuum unit, vacuum pump in the generator, high vacuum and high vacuum unit unit.

low vacuum for its high working pressure, large displacement, and how to vacuum equipment, transport presoak, vacuum filter, vacuum drying machine equipment such as vacuum degassing. Low common main valve, vacuum unit capacity of reciprocating pump, water ring pump, vacuum pump skeleton seal mechanical pump, screw vacuum pump, try the wet roots vacuum pump and jet pump, carbon molecular sieve adsorption pump, such as the discharge air type vacuum pump can be directly, but the level of the cleaning is based on extraction body, environment humidity, and his standard, shall be equipped with dust removal equipment, water equipment for oil and gas separator, dry manic trap.

in the vacuum unit, must apply large pumping speed and get all kinds of vacuum in the vacuum system software, such as coating machine, vacuum smelting, true air quality treatment and medicine, chemical, electric welding welding and other manufacturing industries. Skeleton in the past by vacuum unit roots vacuum pump + time + vacuum sealed mechanical pump, water ring vacuum pumps and double roots vacuum pump as the composition. With screw vacuum water pump has no oil vacuum pump, such as roots vacuum pump + screw vacuum pump in the vacuum unit also slowly increase without oily be soiled, wider adaptability.

high vacuum in the molecular structure of flow unit work cases, work pressure section in the 10 ^ - 2 ~ 10 ^ - Pa 6, displacement and large pumping speed, general condition main pump the diffusion pump, molecular pump, titanium sublimation pumps and ultra-low temperature condensate pump to fill, because they can't work under air immediately, and therefore must be equipped with pump and drainage pump, etc. , in front of the special circumstances in order to avoid the standard air pressure fluctuation must also be equipped with pump and air compressor air tank, etc.

high pressure vacuum unit work section in 10 ^ - 6 ~ 10 ^ - 10 pa, must in the limits of the main valve vacuum 10 ^ - 7 ~ 10 ^ - Above 8 pa and in ensuring working pressure segment relatively pumping speed, such as accidentally ion pump, turbo molecular pump, etc. , and the system up to protect the materials rules can bear 200 ~ 450 ℃ high temperature baking and ensure that the low leakage rate and the exhaust rate.

the main products are vacuum pump manufacturer V, VG, VI, VZ,. vn, LRP, 2 bv series water ring vacuum pump, X, GVD (gnu visual debugger) series rotary vane vacuum pump, what ZJ had roots vacuum pump series, GXS, DHS, VSD, GHS series screw vacuum pump, DZS series claw pump, the central vacuum system, etc. Contact phone number 13928410990.
