Vacuum pump is a large-volume and wide-ranging product. The output is large and the output value is not high, but it is An indispensable basic product that directly affects the performance and quality of vacuum complete equipment. It has a wide range of applications in the industrial field.

According to different working conditions and needs, there are many types of industrial vacuum pumps. Today we will introduce several main types Industrial vacuum pumps, their characteristics and main application areas.

· rotary vane vacuum pump
Introduction: Rotary vane pump is one of the main pumps to obtain low and medium vacuum. According to the required vacuum degree, a single-stage rotary vane pump or a two-stage rotary vane pump can be used. Among them, the application of two-stage rotary vane pumps is more common.
Features: low cost, low noise, easy maintenance, more energy saving.
Application fields: various production and scientific research fields, such as vacuum packaging machines, waste oil extraction.

·Roots vacuum pump
Introduction: Roots pump is a kind of vacuum pump without internal compression. The pump is equipped with two blade-shaped rotors that rotate synchronously in opposite directions. There are small gaps between the rotors, the rotor and the inner wall of the pump casing without contacting each other. .
Features: compact structure, can be installed horizontally or vertically; condensable gas can be pumped out; quick start-up, reaching the ultimate pressure in a short time.
Application fields: petroleum, chemical industry, plastics, pesticides, aerospace simulation, metallurgy, textile and other industrial fields.

·Dry screw pump
Introduction: High-tech products. The core part of the screw pump is the screw rotor, which is designed and solved by a three-dimensional curved surface mathematical model. The entity of the model is processed on the coordinate-free CNC equipment. It has high precision, reliable quality and stable performance, ensuring long-term trouble-free operation of the product.
Features: high vacuum; anti-corrosive gas; good performance of removing solids; no contact between the rotors, no friction, continuous long-term operation.
Application areas: papermaking, food, medicine, medical equipment, information engineering, bioengineering, microelectronics, metallurgy, chemical industry, petroleum, aerospace, etc.

·water ring vacuum pump
Introduction: The water ring pump is a kind of rough vacuum pump. The ultimate vacuum it can obtain is 2000-4000Pa. It forms a unit with the vacuum pump, and the vacuum degree can reach 1-600Pa. It can also be used as a compressor.
Features: simple structure, easy maintenance, flexible configuration, stable and reliable work.
Application areas: coal mines, chemicals, pharmaceuticals, building materials, electrical appliances, plastics, metallurgy, etc.

· scroll vacuum pump
Introduction: The new generation of oil-free mechanical pumps have very high technical content in design and production, and have incomparable advantages in the field of oil-free cleaning, so they are highly praised by the market.
Features: Clean and oil-free, low operating cost, long working life, high reliability, and low noise.
Application fields: pharmacy, chemical industry, scientific research, laboratory, etc.

· Clawless Vacuum Pump
Introduction: The claw pump is a variable volume dry vacuum pump with a claw-shaped rotor.
Features: oil-free, non-contact operation; long-term stable maintenance of ultimate vacuum; high pumping efficiency; almost zero maintenance during operation.
Application fields: coating, single crystal furnace/polycrystal furnace, vacuum drying, leak detection equipment, gas recovery system, energy saving lamp, central/home air conditioner, etc.

· turbomolecular pump
Introduction: It is a vacuum pump that uses a high-speed rotating impeller to transfer momentum to gas molecules, so that the gas molecules produce a directional flow and pump air.
Features: The pumping speed is between 10 and 2700L/S; it is not affected by high load or impurity gas intrusion; intelligent design; small size; powerful.
Application areas: coating, optical industry, semiconductors, transformers, etc.

· oil-free piston pump
Introduction: Also called reciprocating vacuum pump, it is divided into single cylinder and multi-cylinder in structure. When working, the reciprocating action of the piston in the cylinder causes the cylinder internal volume to change repeatedly to achieve the purpose of suction and discharge.
Features: high efficiency and energy saving, stable operation, low noise, low temperature rise, small size, simple structure, safe and oil-free operation.
Application areas: spreaders, scientific research, laboratories, printing industry, etc.

Others include: micro-oil screw pumps, carbon vacuum pumps, and various vacuum units. Industrial applications are also very important.
