Product Name:LGF/LGBF Series Anti-corrosive Screw Dry Vacuum Pump
Screw vacuum pump has a series of advantages, such as wide pumping range, simple and compact structure, no friction components in the pump cavity, low energy consumption, no waste liquid discharge and low operating cost. Therefore, it is widely used in semiconductor, photovoltaic industry, chemical industry, pharmacy, petrochemical, space simulation, low pressure wind tunnel and other fields. Working principle of screw vacuum pump: a pair of synchronous gears drive the counter rotating screw. There is a certain gap between the screw and the screw, and between the screw and the pump chamber. There is no metal to metal contact. Thus, during the rotation of the screw, the extracted gas is sucked in from the air inlet and discharged to the exhaust port, as shown in the figure below.
Advantages
1.New rotor: The new variable pitch rotor has uniform meshing and good sealing
2.Cooling mode: Air-cooled structure, wider application scenarios
3.Anticorrosion: A variety of anti-corrosion coatings are available
4.Simple maintenance: Simple structural design, open the front cover to clean the pump chamber, 1 person can easily complete on site.
5.Low energy consumption: Replace water ring vacuum pump, solve sewage discharge and reduce energy consumption
6.Intelligent: PLC intelligent control, with functions of automatic cleaning, liquid level alarm, vacuum regulation, etc
7.Lightweight: Small and lightweight, it is easy to move

Application scenario
Especially suitable for vacuum applications where cooling water is absent: including oil and gas recovery; Organic solvent recovery; Dye, coating, adhesive processing; Plastics and resin processing; Laboratory; Food processing; Coating technology
Requirements for vacuum pumps in chemical processes
Due to the harsh working conditions and long working cycle of the chemical process, the vacuum pump must be reliable, durable and stable, and must also have the following properties:
1.Capable of handling vapours from various solvents without damaging the pump
2. It will not pollute the process and environment
3.Waste generated shall be minimized
4. The vacuum pump shall be corrosion resistant
5. Capable of handling flammable gas or steam
Vacuum Solutions
Dry vacuum technology is essentially a non-contact, non-wear design that does not rely on sealing fluids or lubricants to generate and maintain the desired degree of vacuum. In modern industrial manufacturing, dry vacuum pump is helpful to reduce operating costs, improve working conditions and extend normal production time. In addition to faster and more efficient operation, dry vacuum pumps also have significantly lower maintenance requirements and longer service life. Yining dry vacuum pump compact design, low noise, good cooling effect，is the best alternative to liquid ring pump products.
