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.
The water-lubricated air compressor produced by Shanghai granklin group does not need to be treated. because water lubrication is adopted, it can be used only by matching the cold dryer and air storage tank at the back end and configuring filters according to special needs.
View detailsChina is rich in coalbed methane resources. Accelerating the development of coalbed methane can not only alleviate the contradiction of natural gas shortage, but also ensure the safety of coal mines and reduce air pollution. Choosing air compressor for coalbed methane project, the better choice is to choose the current market
Small air compressor common piston air compressor, screw air compressor, screw air compressor miniaturization integration in today is also very common. The 5.5KW screw air compressor is a small product. The small water-lubricated air compressor produced by Shanghai Grank Group has stable gas supply and no oil. Many small businesses, as well as laboratories and other users are very fond of purchasing small air compressors.
View details1. Check the dryer: The dryer is a good way to remove moisture from the air, and the dryer is an inseparable part. Like compressors, dryers are affected by changes in temperature and humidity. As the seasons change and the warm days come
View detailsShanghai Granklin Group is engaged in the production of water-lubricated air compressors. It is a large-scale enterprise in the oil-free screw air compressor industry. There are many cases to visit in China. For the problem of the price of oil-free water lubrication screw air compressor, many people will encounter it when purchasing equipment. Why is the oil-free water lubrication screw air compressor so expensive?
View detailsIs there really a "oil-free air compressor manufacturer" with 100% oil-free compressed gas? For companies that have not used "oil-free air compressors", it is normal that they do not understand "oil-free air compressors".
The choice of medical air compressor is one of dry oil-free air compressor and water lubricated oil-free air compressor, which scheme will be better. I need to talk about the advantages and disadvantages of the two schemes in order to better choose a suitable medical air compressor.
Traditional air compressor lubricating substances used in the oil, then the oil-free screw air compressor is through what lubrication? Common water as a lubricating substance can be done in the air without oil, compression process without oil involved in compression to maintain the purity of the gas.
View detailsGenerally, the service life of carbon steel itself is not long. In addition to the process of making gas storage tanks, the service life of gas storage tanks is about 10 years, which was generally 7 years before. If it is a simple pressure vessel, it must be replaced after 10 years. If it is fixed
[Water lubricated single screw air compressor] In order to make the water lubricated single screw air compressor run normally and reliably and ensure the service life of the air compressor unit, a detailed maintenance plan must be formulated, and the fixed person operation, regular maintenance, and regular inspection Maintenance, keep the oil-free silent air compressor unit clean, oil-free, and dirt-free.
