The oil content of compressed air refers to the mass or volume concentration of liquid or solid grease, particles and other impurities carried in the compressed air. This parameter is very important for many industrial applications, because compressed air with high oil content may have adverse effects on some industrial equipment and production processes, such as wear of mechanical parts and product quality. In addition, in the food, pharmaceutical and other industries, it is also necessary to use compressed air with low oil content to ensure that the products produced meet hygiene standards.
The oil content of compressed air is usually expressed in ppm (parts per million), which indicates the amount of a trace substance in a mixture. In practical applications, the oil content of compressed air is affected by many factors, such as the quality of the oil and gas separator, the blockage of the oil return pipe or the oil return check valve, the opening pressure of the pressure maintaining valve is too low, the use pressure is too low, and The quality of the oil appears foam.
In order to ensure that the quality of compressed air meets the relevant standards and requirements, it is necessary to regularly test and maintain the compressed air system. This includes monitoring the oil content of the compressed air system, replacing the oil and gas separator core and other components in time, maintaining the smooth flow of the oil return pipe and ensuring the normal operation of the pressure maintenance valve. In addition, some advanced compressed air treatment technologies, such as adsorption, infrared spectroscopy, ion migration, etc., can be used to detect the oil content in compressed air to ensure that the quality of compressed air meets relevant standards and requirements.
Air compressor plays a key role in coal chemical process. Its core role is to compress gas volume, improve gas purity, optimize process quality, and directly improve the production efficiency of coal chemical industry. The following is a specific analysis: 1. gas compression and volume optimization coal chemical industry.
Q: What is the difference between micro-oil air compressor and oil-free air compressor? A: The compression process of micro-oil air compressor is still involved in lubricating oil. Oil-free air compressors such as Shanghai Granklin Group's "water-lubricated oil-free air compressor" are 100%
Answer: In terms of stability, screw air compressor and scroll air compressor are almost the same, exhaust pressure and exhaust volume are very stable, and the failure rate is low.
On the site, multiple units or types of work may use air compressors, depending on the specific needs of the site and the type of work. Generally speaking, the following units or types of work may use air compressor: construction unit: construction unit is carrying out concrete spraying
The appropriate gas flow rate of the factory gas shall be comprehensively determined according to the specific equipment requirements, process requirements and future expansibility. The core principle is that the total gas consumption shall cover the gas demand of all in-use equipment and reserve 20% allowance. The following is a specific analysis: 1. gas flow demand
There is no definite time standard for the replacement of air compressor maintenance oil. For general mineral lubricating oil, 2000-3000 hours are recommended, semi-synthetic lubricating oil 4000-6000 hours are recommended, and fully synthetic lubricating oil 6000-8000 hours are recommended. Maintenance and replacement of lubricating oil depends not only on oil
When choosing a permanent magnet variable frequency air compressor, you cannot rely solely on the brand, but also need to consider the actual needs and budget, so as to choose the appropriate model and specifications. Shanghai Granklin Group also produces permanent magnet variable frequency air compressors, which use high-efficiency permanent magnet synchronous motors.
Q: What is the difference between power frequency and permanent magnet frequency conversion? A: The motor of the power frequency air compressor is running at a fixed speed and full load every time it starts. The motor of the permanent magnet variable frequency air compressor has less impact on the power grid, which is to gradually increase the speed to reach the air pressure and maintain the pressure.
Screw air compressor host imbalance may have the following reasons: power supply problems: voltage imbalance or power supply fluctuations, and poor contact of a contactor may lead to host imbalance. Check whether the three-phase voltage is balanced, if the voltage is unbalanced, it will
When choosing the size of the air compressor, the skin care factory is really a bit like choosing a fitting dress for the factory. If the choice is too large, it may waste energy and space; if the choice is too small, it may not meet the production needs. So, how can I find that & ldqu
