Q: Is there any difference between an oil-free air compressor and an ordinary air compressor?
Answer: There is a difference.
The oil content of the gas compressed by the oil-free air compressor is oil-free. For example, the water-lubricated oil-free air compressor produced by Shanghai Granklin Group uses water as a lubricant at the head of the air compressor, and there is no lubricant involved in the work.
Ordinary air compressor because the air compressor head needs lubricating oil, so the compressed gas oil content is relatively high. Can not be used in medicine, chemical, food and other fields.
The exhaust pressure of most air compressors is set to 8kg (0.8MPa or 8bar), mainly because this pressure value has reached a comprehensive balance in terms of applicability, equipment compatibility, energy consumption and safety, and is the "golden pressure" in industrial applications.
As the key equipment in industrial production, the reliability and stability of air compressor are very important to ensure the continuity of production process and product quality. Regular maintenance of air compressors is to ensure long-term stable operation, prolong service life, improve energy efficiency and avoid sudden
The main uses of the 1. power industry: compressed air system for instruments, compressed air system for ash removal, compressed air system for miscellaneous factories, water treatment including boiler make-up water treatment and industrial wastewater treatment system, and equipment power pressure in hydropower stations.
The exhaust temperature of a water-lubricated oil-free machine is affected by many factors, including the efficiency of the cooling system, the ambient temperature, and the workload of the machine. Under normal circumstances, the exhaust temperature of water-lubricated oil-free machine is not higher than 65 ℃. This temperature range is in the machine
The inspection cycle of the air compressor can be determined according to different standards and actual conditions. The following are some common inspection cycles and their basis: 1. national mandatory inspection cycle According to relevant national laws and regulations, air compressors are special equipment and require mandatory inspection
There is a close relationship between the gas production and gas consumption of the air compressor. Gas production refers to the ability of the air compressor to continuously produce compressed air per unit time, usually expressed in cubic meters per minute (m & sup3;/min) or liters per second (L/s). Gas consumption, on the other hand, refers
Air compressors are widely used in the biomedical industry, mainly in the following aspects: Equipment cleaning and disinfection: The compressed air provided by the air compressor can be used for equipment cleaning and disinfection. By purging the surface and interior of the equipment with high-pressure air, there can be
There is a close relationship between air compressor and gas consumption. The main function of the air compressor is to compress and provide air, so its performance directly affects the air consumption. Specifically, the displacement of the air compressor (that is, the discharge per unit time, converted to the suction state
In food production, compressed air directly contacts food or production equipment, and its quality directly affects food safety. The following are the core standards and application specifications of compressed air for food: 1. international general standards 1. ISO 8573-1:2010 quality grade solid particles
The normal negative pressure value of the air inlet of the air compressor should generally be between 0.5 and 0.7bar. This range can ensure the normal operation of the air compressor and avoid overheating or overpressure. At the same time, the limit value of the suction negative pressure of the air compressor is about-50kPa (I .e. -0.5bar), but the actual
