Product Name:
LG Series Equal-Pitch High Vacuum Screw 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 equal 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

The limit pressure of claw type dry vacuum pump developed by Shandong Yining Environmental Protection Technology Co., Ltd. is ≤ 1Pa, and the pumping speed is (4~1600) L/s. Our company has developed a claw type dry vacuum pump made of graphite composite materials, which can be applied to the working conditions of strong corrosive media in the chemical industry, such as perchloric acid, hydroiodic acid, sulfuric acid, hydrofluoric acid, hydrobromic acid, hydrochloric acid, nitric acid, etc. At present, the vacuum pump has been used in the chemical industry in evaporation, distillation, drying, concentration and other working conditions.
