Many customers have some difficulties in the difference between oil-free scroll air compressor and oil-free screw air compressor. There are many similarities and differences between the two. The following is a comparison between oil-free scroll compressor and oil-free screw compressor based on compressed air quality, pressure ratio, structure, manufacturing cost, operating cost, exhaust pipe working pressure, power range and flow range.
Compressed air quality: they can produce all oil-free clean gas, to achieve high-grade gas requirements.
Pressure ratio: oil-free scroll air compressor single pole pressure ratio is high, can achieve 10. General oil-free screw machine single-pole pressure ratio is low, generally <3, for power with refrigeration compressor to use 2-stage compression.
Manufacturing cost: In comparison, the cost of oil-free scroll air compressor is lower, with no oil seal, no shell, no interlayer, no synchronous gear, no air seal, and low manufacturing precision.
Operating cost: The operating cost of the two oil-free air compressors is lower than that of general equipment.
Discharge pressure: oil-free scroll compressor in the middle of 0.6 ~ 0.9Mpa, oil-free screw <0.25mpa (single pole).
Power range: oil-free scroll compressor 0.3 ~ 37Kw middle, oil-free screw compressor in the middle of 45 ~ 250Kw.
Flow range: oil-free scroll compressor 0.39~6.8m & sup3;/min, oil-free screw compressor 7.2~44.0m & sup3;/min.
There may be many reasons why the air compressor cannot start after being shut down for too long, mainly including the following aspects: Electrical problems: The start-stop control system of the air compressor is composed of various control circuits and safety circuits. When it cannot be started after being shut down for too long, it needs to be checked first
As the main gas equipment of the production enterprise, the operation and management of the air compressor should be carried out by professionals. Of course, there are also requirements for managers. The management personnel shall clarify their responsibilities and do a good job in the operation and maintenance of the air compressor to ensure the stable operation of the equipment. So...
View detailsRefueling air compressor and oil-free air compressor have their own characteristics. Which one is better depends on your specific needs and preferences. Refueling air compressor, like a powerful strong man, because of the use of lubricating oil, it can run more smoothly, reduce the machine
How long does the air compressor need to discharge water once, mainly depends on the use environment of the air compressor, the working load and the characteristics of the equipment itself. The following are some general guidelines: Routine water discharge frequency: Under normal working conditions, air compressors are generally recommended
The choice of air compressor with oil or without oil depends mainly on the specific use needs and environment. Oil compressors require lubricating oil during operation, which may cause pollution in some environments. However, they usually have high durability and low cost
In the field of air compressors, PPM(Parts Per Million) is usually not a parameter used to directly describe the performance of air compressors. However, in the quality detection of compressed air, PPM is an important indicator, it is the representation of volume concentration, used to quantify the compressed air
The pressure of the air compressor used in the factory and its importance In industrial production, the air compressor, as an important power equipment, provides the required power source for various pneumatic tools and machinery. The pressure of the air compressor is one of the key indicators to measure its performance.
There are obvious differences in the design and operation principle of micro-oil and oil-free screw compressors. The following are the main differences between them: Lubrication method: Micro-oil screw compressor: Use a very small amount of lubricating oil to lubricate the screw rotor and bearings. These lubrication
In the air compressor industry, permanent magnet frequency conversion technology has become the key technology to improve energy efficiency and stability. So, which brand of permanent magnet variable frequency air compressor is better? This article will focus on the water-lubricated screw air compressor produced by Shanghai Grankering Group, with its
The air compressor will produce a large amount of moisture and sediment during operation. If the moisture is not discharged in time, it will cause damage to the equipment. The following is the method of discharging water from the air compressor: manual drainage method: turn off the power supply of the air compressor to ensure safety.
