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.
In the air compressor industry, permanent magnet frequency conversion technology is leading a revolution in energy efficiency. As a leader in this field, Shanghai granklin group takes its water lubricated screw air compressor products as the core, showing excellent innovation ability and market competitiveness.
Compressed air quality standards for the semiconductor industry usually include a number of indicators, such as particulate matter, humidity, oil content, microbiological and chemical pollutants. The specific values of these standards may vary depending on the production process and application requirements. A
The solution to the excessive water output of the air compressor 1. the core reason for the excessive water output. During the operation of the air compressor, the temperature rises when the air is compressed, and the water vapor in it will condense into liquid water with the decrease of temperature. If there is too much water, it is usually caused by the following reasons: ring
The continuous working time of oil-free air compressor is a very interesting topic! Although it is called "oil-free", it does not mean that it can work endlessly! In fact, the continuous working time of the oil-free air compressor will be affected by many factors.
Air compressor (referred to as air compressor) is a kind of equipment that compresses air and stores energy. Its output compressed air is widely used in industrial, commercial, civil and special fields as a power source or process medium. The following are the main application scenarios and specific use of air compressors
The oil-free lubrication compressor realizes lubrication and heat dissipation in an oil-free environment through special design. Its core methods are as follows: 1. lubrication method Water lubrication technology principle: water replaces lubricating oil, and realizes lubrication, cooling, sealing and noise reduction through water film Four functions. Water under pressure
The difference between oil-free screw air compressor and oil-free screw air compressor is mainly reflected in the following aspects: 1. working principle Oil screw air compressor: lubrication and cooling: during the compression process, lubricating oil participates in the compression to lubricate the main engine The role of internal running parts, while taking away the cause
There is often a need to repair screw air compressor technology search air compressor universal password, really universal password? The answer is: NO. The passwords of each manufacturer are different. I can set whatever I want. I can only say that some of the machine passwords that have been repaired have been put on the Internet by technicians.
View detailsThe cold dryer in the air compressor, that is, the freeze dryer, plays a vital role. The following is a detailed description of its function: 1. remove moisture and impurities. Working principle: The cold dryer uses the refrigerant to exchange heat with the compressed air to reduce the temperature of the compressed air to the dew point.
Whether the air compressor is a contraband can be summarized from the following aspects: From the perspective of laws and regulations: According to the current relevant laws and regulations and entry-exit regulations, the air compressor is not classified as a contraband. However, specific provisions may vary by region and time
