What is the second air compressor?
Two-stage compression adopts double head and double motor. The compression process for secondary increase is called secondary air compressor.
Two stage compression in the screw air compressor industry, is a very common demand!
Users need no oil, water lubrication, but also need to reach a certain pressure, then the first level of compression can not reach how?
The best way is to use two-stage compression to increase the pressure.
water lubrication is very mature and extensive in the application of oil-free air compressors. During the process from suction to exhaust, no drop of grease is involved in the work process.
Compared with the oil screw machine, the water lubricated air compressor uses water as the lubricating sealing material, which will be lower when the pressure and gas volume are the same as the power.
However, with the development of science and technology today, no oil is the future trend, and no one wants to reduce the yield of products because of a drop of oil.
Shanghai Granklin Group, the production of water-lubricated screw compressors can be used as secondary air compressors according to pressure requirements. Increase the outlet pressure.
Screw compressor and scroll compressor which is good? Screw compressor and scroll compressor have their own advantages and disadvantages, suitable for different applications. The following are some comparisons between them: Efficiency: Screw compressor: Usually in the middle and high
The choice of air compressor oil or not is not a simple question, but needs to be considered according to the specific application scenarios and needs. The following is a comparative analysis of oil-free air compressors and oil-free air compressors to help you understand the advantages and disadvantages of the two more clearly:
Air compressor is not the greater the working pressure, the better. The following is a detailed analysis of the working pressure of the air compressor: Work efficiency and energy consumption: The working pressure of the air compressor is set too high, which will cause its operating efficiency to decrease and energy consumption to increase. Because under high pressure, the air compressor needs to consume
Air compressor blowing out of the gas with water is a normal phenomenon. The following is a detailed explanation of this phenomenon: The cause of 1. moisture Humidity in the air: The air in its natural state always contains a certain amount of moisture, the so-called humidity. When the air is compressed, this water
When choosing which is more suitable for continuous operation between oil-free and oil-free air compressors, multiple factors need to be considered, including the working environment, use requirements, maintenance costs, and equipment life. The following is a comparison of two kinds of air compressor: oil air compressor: advantages
Compressed air plays a vital role in the pharmaceutical production workshop. Its use is extensive and strict, which is directly related to the quality, safety and production efficiency of drugs. The following are the core uses and key requirements of compressed air in pharmaceutical production workshops: 1. core uses
The working pressure of the air compressor is an important technical parameter, which is usually determined according to the specific application requirements and the design of the air compressor. Generally speaking, the working pressure range of the air compressor is wide, which can meet the needs of different industrial occasions. In common industrial applications
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.
Q: National standard food industry requirements for compressed air? A: Oil-free compressed air. The following are the compressed gas standards for the food industry: 1. Indirect contact; blowing bottles, packaging, etc. The quality of compressed air shall conform to the following ISO8573.1-2010
The replacement time of the air compressor is not a fixed value, but is affected by a variety of factors, including the type, quality, use environment, maintenance, frequency and intensity of use of the air compressor. The following is a detailed analysis of these factors, and based on
