Oil-free air compressor brand, the market response to good Shanghai Grencklin Group specializes in air compressor research and development and production and sales of manufacturing enterprises.
Air compressor (English: air compressor), it is the main body of the air source device, which belongs to general machinery. It is a device that converts the mechanical energy of the motor into pressure energy or kinetic energy. It is used to increase the pressure of the air and is compressed air. Generating device.
The use of compressed air is generally divided into two categories:
power gas source: Compressed gas is used to drive other power machinery.
Process gas source: Compressed gas becomes an integral part of the final product.
air compressor commonly used terminology:
air compressor pressure: usually the discharge pressure given on the compressor nameplate is gauge pressure, not absolute. against the pressure.
Common pressure units: bar, MPa, air compressor industry said "kg" refers to "bar", that is, 1kg refers to 1bar,1MPa (MPa) = 1000kPa (kPa),1bar (bar) = 0.1MPa.
Air compressor volume flow: It is also called displacement or nameplate flow in China. The gas volume discharged by the air compressor per unit time is converted to the intake state, that is, the volume of suction. According to national standards, the air compressor The actual displacement of ± 5% of the nominal flow is qualified.
Common units: m3/min, L/s.
oil content of air compressor gas: the mass of oil (including oil droplets, suspended particles and oil vapor) contained in unit volume of compressed air, usually what we call PPM is the unit of weight ratio: PPM, and one millionth of 1kg is milligram.
Air compressor pressure dew point: refers to a certain pressure of the gas cooled to a certain temperature, which contains unsaturated water vapor into saturated water vapor precipitation, this temperature is the pressure dew point of the gas. Atmospheric dew point refers to the temperature at which the gas is cooled to the temperature at which the unsaturated water vapor contained in the gas is converted into saturated water vapor under standard atmospheric pressure. In the air compressor industry, the dew point indicates the degree of drying of the gas.
Specific power: refers to the power consumed by the compressor unit volume flow. It is an important index to evaluate the energy efficiency of the compressor. Air compressor specific power unit: KW/m3.
If you need to purchase a water-lubricated air compressor, please contact granklin group. our professional sales will match you with the air compressor type suitable for your pressure and flow.
For ordinary production industries, the requirements for air compressors are not very strict. At this time, you can choose an air compressor with oil or micro-oil. After all, the cost of an air compressor with oil or micro-oil is different. And for some of the air compressor requirements are more stringent enterprises, such as laser cutting, medical and other industries, will be more stringent requirements on the air compressor, the need for air compressor can reach the standard of oil-free. This time to choose an oil-free air compressor.
Permanent magnet variable frequency air compressor has always been sought after by industrial enterprises with the characteristics of high efficiency, energy saving and environmental protection, and its energy saving effect is also very considerable. In recent years, more and more air compressors with high energy consumption have been replaced by permanent magnet variable frequency air compressors on the market.
When choosing an air compressor, when transitioning from an oil-injected screw air compressor to an "oil-free screw air compressor", we will always have doubts about unknown products that we do not understand ". After all, air compressor family after years of development, has produced many kinds of compressor. The "water-lubricated screw air compressor" produced by Shanghai Granklin Group is one of the "oil-free screw air compressors.
What is the difference between a fixed screw air compressor and a variable frequency screw air compressor? Most of the variable frequency air compressors are also fixed, and the fixed screw air compressors include variable frequency air compressors and water lubricated air compressors produced by Grantklin Group are also fixed.
View detailsAir compressor in the mechanical processing industry is very important, can be very efficient to promote the mechanical processing capacity, today to talk about how to choose air compressor in this industry. CNC machine tool is an important tool of modern manufacturing industry, is a kind of high-tech mechatronics
When we choose an oil-free water-lubricated air compressor, in addition to conventional parameters such as displacement and power, we generally pay attention to its cooling method. Generally, there are two main cooling methods for an oil-free water-lubricated air compressor: water-cooled and Air-cooled, then these two cooling methods
With the blockade of China's high-tech technology and equipment by the United States in recent years, such as the recent mention of advanced technology and equipment used in the semiconductor and chip industries: Japan's Shin-Yue, the United States Dow, Asmai, etc. However, the realization of the semiconductor and chip industry's gradual national
The reputation of "oil-free air compressor" depends on the users who have used it. When a brand reaches a certain user base, most people say that it is easy to use and the gas supply is stable, then this "oil-free air compressor manufacturer" must be a "oil-free air compressor enterprise" with good reputation and excellent product quality ".
The water lubricated air compressor produced by Shanghai granklin group is widely used in metallurgy, machinery manufacturing, mining, electric power, textile, petrochemical, textile and other industries. Our cases cover all provinces and cities in China.
How long the air compressor can generally work continuously depends on a variety of factors, including the type of air compressor, the use of the environment, maintenance and load conditions. From the perspective of air compressor types, common piston air compressors are usually not suitable for long periods of time due to structural characteristics.
