for compressed air, the user's requirements are also different, so the technical indicators for calibrating compressed air are: pressure, flow, and quality. Every user ultimately needs a certain pressure, a certain flow, a certain quality of compressed air.
01. Selection of working pressure
working pressure, usually called exhaust pressure, working pressure refers to the highest pressure of the air compressor discharge gas; There are many expressions of pressure units. The commonly used working pressure units are: Mpa or bar,1Mpa = 10bar; The pressure unit is usually called: Kg (kg) 1bar = 1Kg. When preparing to buy an air compressor, first determine the working pressure required by the gas end, add a margin of 1-2bar, and then select the pressure of the air compressor.
02. Volume flow
volume flow is usually called exhaust volume. Volume flow refers to the volume of gas discharged from the air compressor per unit time under the required exhaust pressure, which is converted to the intake state; the volume flow unit is: m3/min (Cubic/minute) or L/min (liter/minute),1m3 (cubic) = 1000L (liter); the commonly used flow unit is m3/min (cubic per minute). Should first understand the gas consumption of all gas equipment, the general recommendation is that the air compressor exhaust volume needs to be 1/4 larger than the total gas consumption of gas equipment, which is conducive to overload and the use of additional dust blowing in daily work.
03, the power of the air compressor
the power of the air compressor refers to the nameplate power of the matching drive motor or diesel engine; the unit is KW (kilowatts) or HP (horse/horsepower),1KW is about 1.333HP. The selection power of the air compressor is to meet the working pressure and volume flow conditions, the power supply capacity can meet the use of power.
Power frequency and frequency conversion
power frequency and frequency conversion selection, if the daily working time is more than 20 hours, it is recommended to buy permanent magnet frequency conversion air compressor, permanent magnet plus frequency conversion adjustment machine, primary energy consumption is conducive to energy saving. If the daily working hours are short and the gas consumption time is less, it is recommended to choose a cheap and durable power frequency air compressor. Both have their own advantages and choose according to their own needs.
The factory needs to expand production capacity and prepare to purchase a new set of screw air compressor. At this time, the problem facing is how to choose the brand of screw air compressor. Before purchasing screw air compressor, I sorted out the brands of screw air compressor sold in the domestic market: the first-line brand of screw air compressor is good: Granklin
View detailsSingle screw air compressor in the selection process is often in order to purchase oil-free air compressor, so in Shanghai to do single screw compressor and oil-free air compressor industry to do better is which? "Shanghai Granklin Group" in the water lubrication oil-free air compressor research and development, production, sales, is a comprehensive production of air compressor enterprises.
View detailsCompressed air is ubiquitous in modern industry. Electronics, medicine, food, chemical and many other fields have high requirements for the quality of compressed air, requiring pure oil-free and dust-free compressed air. Water-jet screw oil-free air compressor is an emerging technology
Structural aspect: The twin-screw air compressor has few moving parts and simple structure. The rigidity of the male rotor is higher than that of the female rotor, but the male rotor also bears most of the load. The rigid load ratio of the male and female rotors is close, the deformation is uniform, and the volume coefficient is high. The single screw air compressor has three rotating shafts
Air compression is called air compressor for short. What is the air compressor used for? Xiao Shen sells as an air compressor to solve your doubts: The main function of the air compressor is to compress gas and provide it to production and processing after pressurization at atmospheric pressure. Simply put, an air compressor is a kind of gas supply equipment, which is a device that converts mechanical energy into gas pressure. Its structure
In the post-processing equipment of the screw air compressor, there are mainly air storage tanks, dryers and filters. Dry compressed air can ensure the operation of air compressor air system and production process. The role of the dryer is to eliminate the condensed water in the compressed air and ensure the discharge of dry and clean compressed air. In the equipped with the relevant dry
Air compressor is one of the main mechanical power equipment of many enterprises, and it is very necessary to maintain the safe operation of air compressor. Strict implementation of the air compressor operating procedures will not only help extend the service life of the air compressor, but also ensure the safety of the air compressor operator.
The main function of energy-saving variable frequency air compressor is to provide compressed air for all kinds of industrial systems. Obviously, as industrial equipment, it can only be trusted by everyone with good performance, and a good energy-saving variable frequency air compressor is also proved in actual use. It is able to adapt to all kinds of high-demand industrial operations.
It is best to use the original lubricating oil or the lubricating oil recommended and specified by the manufacturer. One is the oxidation resistance and thermal stability of compressor oil. For compressor oil, its oxidation resistance and thermal decomposition resistance can not only prevent oil thickening, deposition and sludge formation, but also extend the service life of compressor oil, thereby saving the high cost caused by replacement, shutdown and oil cleaning;
Medical oil-free air compressor refers to the kind of air compressor suitable for use in medical environmental health conditions. It requires precision, stronger reliability, environmental protection and quiet, fresh and clean compressed air, and the output gas can directly contact the human body. Displacement in less than 1m 3/min medical air compressor is mostly micro screw reciprocating air compressor, also known as oil-free air compressor, foreign also called micro screw swing air compressor.
