3. What is the operating principle of an air compressor?
An air compressor is a mechanical device that compresses air into high-pressure gas. It is a gas compression equipment with stable operation, low noise, high efficiency and low maintenance cost. Its working principle is to use twin-screw motion to compress the gas to a high-pressure state. The working process includes suction, compression, exhaust and entering the cycle. The specific steps are to suck air into the compression chamber through the air inlet valve, then compress the gas through the rotating screw, and then discharge the gas through the air outlet valve, and the gas will enter a new compression cycle.
4. What is a screw compressor?
Screw air compressor is a common type of air compressor. It is divided into single-screw air compressor and twin-screw air compressor. It adopts high-efficiency pulley transmission to drive the main engine to rotate for air compression. It sprays oil to the air inside the main engine. The compressed air is cooled, and the mixed gas of air and oil discharged from the main unit undergoes coarse and fine separation to separate the oil in the compressed air, and finally obtain clean compressed air. Its main components include the host machine, motor, control system and accessories. It provides continuous trouble-free movement, long service life and simple maintenance, which can save more maintenance costs.

6. What does two-stage compressor mean?
Two-stage air compressor, also known as two-stage compression screw air compressor, refers to a device that compresses air or gas to high pressure. Unlike traditional single-stage compressors, two-stage compressors use two compressor stages to compress the gas separately for primary and final compression. The working principle is: after the air is compressed in one stage, it is cooled by the interstage spray curtain of two-stage compression, which reduces the suction temperature of the second-stage compression, making the compression process tend to be isothermal compression. Compared with single-stage compression, in principle, two-stage compression saves 5~8% energy compared with single-stage compression. The two-stage air compressor has an integrated upper and lower design. There is no pipeline connection between stages. The structure is compact and the pressure loss is small, which also guarantees the energy saving of the whole machine. Two-stage compressors can provide more efficient compression, higher pressures and larger flows and are widely used in industrial, manufacturing and production processes.
7. What is a centrifugal air compressor?
The centrifugal air compressor uses an impeller to drive the gas to rotate at high speed, causing the gas to generate centrifugal force. Due to the expansion flow of the gas in the impeller, the flow rate and pressure of the gas after passing through the impeller are increased, and compressed air is continuously produced.
Centrifugal air compressors are speed compressors. When the air load is stable, centrifugal air compressors work stably and reliably.
① Compact structure, light weight, wide exhaust range;
② Few wearing parts, reliable operation and long life;
③The exhaust is not contaminated by lubricating oil and the air supply quality is high;
④The efficiency is high when the displacement is large, and it is conducive to energy saving.
8. What is a turbine blower?
A turbine blower is a gas compression device based on the centrifuge principle. It consists of a rotating blower wheel and a fixed flow duct. When the gas enters the blower wheel through the air inlet, the blower wheel rotates at high speed, compresses the gas and discharges it from the outlet. Turbine blowers can generate very high air pressure, so they are widely used in various fields that require high-pressure gas.
The turbine blower uses a high-speed rotating turbine (impeller) to create a pressure difference between the suction end and the exhaust end through rotation, thereby generating airflow pressure and also compressing the airflow. The turbine blower has certain pressure ratio and flow characteristics, and can automatically adjust the pressure and flow, and can also work stably in a wide range. Turbine blowers are widely used in high-speed, low-flow scenarios, such as aircraft, air gliders, general engines, etc.
9. What is an oil-free vacuum pump?
An oil-free vacuum pump is a mechanical vacuum pump that can operate without any oil for lubrication.
Advantages and Disadvantages: It has the advantages of simple structure, easy operation, convenient maintenance, and does not pollute the environment. The oil-free vacuum pump has good durability and is a dual-purpose vacuum pump for vacuuming and compression. It is a basic equipment for obtaining vacuum with a very wide range of applications.
Compared with oil pumps, oil-free vacuum pumps have lower vacuum degree and smaller air pumping capacity, but they are small in size, easy to install, simple to maintain, easy to move, do not produce oil smoke, and do not pollute the environment. They are especially suitable for use in laboratories with higher requirements. It is also one of the most commonly prepared equipment in the laboratory. Therefore, when purchasing an oil-free vacuum pump, you must first determine the required working vacuum degree. If the required degree of vacuum is high, the selected vacuum pump must be higher than the required vacuum degree. Otherwise, the vacuuming requirements will not be met. to job requirements. The second is the pumping rate of the oil-free vacuum pump. When selecting the pump, it should be slightly larger than the required pumping rate, so that it can better meet the needs. Finally, check whether the extracted gas is corrosive. Corrosive gas will corrode the pump, so special materials must be used to meet the needs.
Working principle: Its working principle is the same as that of a general positive displacement pump, and it is composed of stator, rotor, rotary vane, cylinder, motor and other main parts. The rotor with rotary vanes is installed eccentrically in the fixed cylinder. When the rotor rotates at high speed, the four radially sliding vanes in the rotor slot divide the pump chamber into four working chambers. Due to the centrifugal force, the rotary vanes are closely attached to the The cylinder wall separates the stator's inlet and outlet, and operates over and over again to change its volume. The inhaled gas is discharged from the exhaust port, thereby achieving the purpose of air extraction.
10. Why use screw compressor?
A screw air compressor is a type of air compression equipment commonly used in industrial and commercial applications. As a new type of air compressor, it is more convenient to operate than traditional piston air compressors, not only because of its stable performance, but also because of its low vibration frequency and low noise, so there is no need to worry about piston noise. Their main purpose is to compress a large amount of air into a smaller volume and provide high pressure and high flow rate of compressed air. The purpose of using screw air compressors is as follows: 1. Providing power: Screw air compressors are the power source for many industrial equipment and tools, such as pneumatic tools, spray painting equipment, refrigeration equipment, etc. They compress air to high pressure and then pipe it to equipment that requires compressed air for power. 2. Store energy: An air compressor can store compressed air in an air tank for emergency use. This method of storing energy can cope with peak gas consumption and sudden gas consumption, providing a stable and continuous supply of compressed air. 3. Processing and production: Screw air compressors play a key role in many production processes. They are used in gas separation, pipeline transportation, material transportation and other processes to provide stable compressed gas and play a vital role in many industrial fields. Screw air compressors can also be integrated with other equipment and systems, such as cooling systems, air conditioning systems, pumping stations, etc., to achieve wider applications and benefits. The most important thing is that the screw air compressor can have continuous trouble-free movement, long service life, and simple maintenance, which can save more maintenance costs.
