Description

The usual vacuum system cannot meet the requirements of clean oil and corrosion resistance, a large number of oil vacuum system was replaced by oil free clean vacuum system, dry oil-free vacuum products, clean and environmental protection would accelerate alternative water ring pump, reciprocating pump, mechanical pump of oil seal type. Screw vacuum pump belongs to the type of non-contact dry pump, it is a kind of ideal pump that is appears in the early ***0s. The advantages are wide range of pumping speed, simple and compact structure, suction cavity components without friction, long life, low energy consumption, without oil pollution, etc.
Screw vacuum pump is a studio that composed of a pair of parallel spiral rotor and the pump body, there is no friction and keeps a certain gap between the rotors and the pump body, the two rotors and the pump body formed a sealed cavity. When the rotors rotate, the gas in the sealing chamber is continuously pushed to the exhaust port. Screw vacuum pump does not need oil to lubricate and water to sealed, pump cavity completely without oil, so the screw vacuum pump is dry vacuum pump oil. It is updated products of a reciprocating pump, water ring pump, oil seal type vacuum pump, rotary vane vacuum pumps, roots pump unit.
Screw vacuum pump of a guide process is equivalent to the level of pump, a plurality of guide screw vacuum pump the equivalent of multistage pump series, relative to multistage tandem dry vacuum pump(the claw type vacuum pump, multi-stage Roots vacuum pump).The gas pressure of the suction is higher than that of the discharge source. Such design makes the discharge of gas will not be mixed with oil material. The power of the motor is transmitted to the active shaft through the coupling device, and the main rotation shaft is transmitted to the driven shaft through the timing gear.   
2.Structure principle and characteristics

●Screw Rotor
 Rotor is divided into uniform pitch and variable pitch of two kinds of structure. The type of LG is uniform pitch. The type of LGP is variable pitch. The rotor is made of five axis machining center precision machining center,After machining, the dynamic balance test of precision G1 level was adopted, to guarantee equipment performance。Screw rotor material according to different working condition is composed of the following three categories:
A、High NI - P alloy plating spherical graphite cast steel surface, suitable for general gas medium or small acid alkali medium.
B、**6L and other stainless steel materials, suitable for stainless steel is not a strong reaction of the acid and alkali media.
C、TA, TC series of titanium material, suitable for most of the medium of acid.
●Timing Gears
   Equal proportional gear is one of the most important parts of screw pump,it can make the screw rotor and the rotor to keep a fixed gap.
●Bearings
   Fixed end bearing is SKF double row thrust ball bearing. Extended end bearing is high load roller bearings. These bearings are able to support high speed and high load operation. At the same time, it can keep the gap between gears and rotors.
●Shaft Seal
The sealing device is composed of a multi lip dry stainless steel rotary sealing and sealing compound.This kind of composite sealing device can prevent the oil material from the former end plate into the shell, and prevent the pump from the pump into the bearing lubrication chamber, and prolong the service life of the pump and reduce the maintenance and improve the reliability of the equipment.
●Lubricating Oil
  Vacuum pump gear box used oil lubrication, oil should be added to the oil more than half of the mirror. If the oil is too little,Bearings, gears and mechanical seal will suffer from abnormal friction. Therefore, when the pump is not in working, please check the oil quantity and condition of oil pollution, in order to decide whether to need to increase or replace the lubricating oil.
3.Features:
1. Clean and environmental protection:This is dry vacuum pump; in the working chamber without lubricate oil. It is in favor of recycling medium, so can acquire the clean vacuum. Without waste oil and waste water to be discharged in working, it is environmental protection vacuum pump.
2. High vacuum:Rotor lines profile optimization design,The ultimate pressure of one LG pump≤1pa,LGP≤5Pa.It has large swept volume in the high vacuum area, high efficiency and lower power consumption.。
3. Anti-corrosion(patent technology):Material of the flow passage components has many choices. Such as titanium alloy, stainless steel, nodular cast iron and so on. Also it can be sprayed by nano ceramic and NIP alloy anticorrosive coating.
4. It can pump condensable gas and the gas with little dust
5. The special design to shaft seal. It can effectively prevent the gear cavity lubricating oil and the pump cavity medium seepage polluting each other (patent technology).
6. The type of LGP is energy saving and low noise (patent technology): When **0L/S screw pump working, the power just 7.5 KW, and noise is lower than *9 dB without muffler.
7. Anti overload design:Variable pitch screw pump with the design of variable frequency speed control  can be started and run at any pressure。
8. Smooth operation
9. Highly standard configuration
*0. Accessories complete
*1. Different industries and different design
*2. Quality and sound spare parts supply
4. Purpose and scope
1. Electrotechnics:Transformer, mutual inductor, epoxy resin vacuum casting, capacitor vacuum oil immersion, Vacuum pressure impregnation.
2. Chemical industry、pharmacy:Product distillation, dry, degassing, material handling.
3.Industrial furnace:vacuum brazing、vacuum sintering, vacuum annealing, vacuum pressed gas quenching, etc
4.Vacuum coating
:Vacuum vapor plating, vacuum magnetron sputtering deposition, continuous coating film winding, ion plating, etc
5. Metallurgy:Special steel smelting, vacuum induction furnace, vacuum desulfurization, degassing.
6.
Aviation、spaceflight。
7.Dry:Voltage transformation vacuum dry, wood drying, Kerosene air box drying, etc.
