Screw air compressor and scroll air compressor are common compression equipment, they have their own characteristics and applicable scenarios. The following is a detailed comparison of these two air compressors:
screw air compressor
working principle:
the screw air compressor is pressurized by the mechanical movement of the master and slave screws. In the suction stage, the air pressure in the screw compression chamber is lower than the atmospheric pressure, and the air is sucked into the compression chamber after passing through the filter device. In the compression stage, the air is confined by the gap between the housing of the compression chamber and the rotating screw. The interaction of the gear and the rack causes the gas to be compressed, and the air pressure and temperature in the chamber gradually increase. When the gas is compressed to the pressure standard, it will be discharged through the outlet valve.
Features:
high efficiency and stability: The screw-type rotating structure has high compression efficiency and can maintain stable output pressure under high load.
Low maintenance cost: simple structure design, less wearing parts, reduce maintenance frequency and cost.
Energy saving and green: adopt advanced control system to automatically adjust the running state and reduce energy consumption.
Customizable: according to the actual needs of enterprises to choose different configurations and models.
A wide range of applications: suitable for heavy industries such as chemical industry, petroleum, electric power, metallurgy, etc., as well as light industries such as food, medicine, and electronics.
Scroll air compressor
working principle:
the scroll air compressor is formed by the intermeshing of two dynamic and static scroll discs of the double function equation type line. The gas is sucked into the periphery of the static disc through the air filter element. As the eccentric shaft rotates, the gas is gradually compressed in several crescent-shaped compression chambers combined by the static and dynamic disc, and then continuously discharged from the axial hole of the central part of the static disc.
Features:
high reliability: Due to simple structure and few moving parts, it is reliable and durable.
Low noise and low energy consumption: smooth operation, low vibration, and almost zero resistance loss of intake and exhaust, so noise and energy consumption are very low.
Low maintenance cost: fewer host parts, fewer wearing parts, small maintenance workload and low maintenance cost.
A wide range of applications: suitable for manufacturing, chemical industry, food and beverage industry, medical industry, textile industry, electronics industry and other fields.
Summary
screw air compressor and scroll air compressor have their own unique advantages and application scenarios. Screw air compressor is famous for its high efficiency, stability and wide range of applications, while scroll air compressor is favored for its high reliability, low noise and low maintenance cost. When choosing, the decision should be made according to the specific application requirements and scenarios.
It is normal to carry water vapor in the compressed air discharged from the air compressor, but it can be effectively controlled by technical means. The following are the cause analysis and solutions: 1. water vapor causes compression and heating effect. When air is compressed, the temperature rises sharply (every 100k increase
Whether the oil-free air compressor is durable depends on a number of factors, including the quality of the air compressor, the use of the environment, the workload and maintenance. First of all, from the quality point of view, the choice of certified brands and models of oil-free air compressor is to ensure
Air compressors are generally not recommended to be placed directly outdoors. The following is a detailed explanation of this problem: the influence of the 1. outdoor environment on the air compressor weather factors: sun and rain: outdoor air compressor is easily eroded by direct sunlight and rain, and long-term exposure may lead to the machine
Whether the electric air compressor belongs to large machinery is actually a bit subjective. Because the term "large machinery" does not have a strict definition, its size is often relative. Generally speaking, electric air compressor
The use of air compressor is as follows: 1. before the operation of air compressor, the following problems should be paid attention to: 1. Keep the lubricating oil in the oil pool within the scope of the scale. Before the operation of air compressor, the oil quantity in the oil injector should not be lower than the scale line value. 2. Inspection
The air compressor is indeed used in the semiconductor process, and its role is very important, which is embodied in the following aspects: 1. provide clean compressed air. The semiconductor manufacturing process has extremely high requirements for air cleanliness, and any tiny dust, Particles or oil mist may affect the core
Cold dryers (freeze dryers) are usually used in conjunction with air compressors to remove moisture from compressed air and ensure the quality of the air source. The working principle of the cold dryer is to use refrigeration technology to cool the compressed air to a certain dew point temperature, so that the water vapor in it condenses
How much is the air volume of 20 cubic meters per minute for the air compressor-take the water lubricated oil-free air compressor of Shanghai Greenland Group as an example. In industrial production, the air compressor is the core equipment providing air source power, and its selection is very important to ensure the stability of the production line.
Q: Air compressor always has water in the air pipe? Answer: Please check whether the cold dryer or suction dryer is working normally, and whether the automatic drain of the gas tank is blocked. Whether the air-water separation device of the air compressor fails, first look for the reason from the above points. If you still can't do it, you need it.
Air compressors are general equipment. General-purpose equipment usually refers to those versatile, versatile mechanical equipment. According to the general engineering equipment classification of mechanical and electrical engineering equipment, air compressors are clearly classified as one of the important equipment. This classification is obtained.
