The exhaust oil content of micro-oil screw air compressor is a key performance index, which directly affects the use effect of air compressor and the safety of subsequent equipment. The following is a detailed explanation of the exhaust oil content of the micro-oil screw air compressor:
standard of oil content:
generally speaking, the exhaust oil content of the micro-oil screw air compressor should not exceed 5ppm (one part per million). However, in practical applications, this value may be affected by many factors.
According to publicly released information, the discharge oil content of micro-oil screw air compressors usually contains 30 to 40 milligrams of oil per cubic meter of compressed air. This range can be converted to ppm units, that is, 30ppm to 40ppm. However, please note that this is a rough range, and the specific oil content may vary depending on the equipment model, brand and conditions of use.
factors affecting the oil content:
performance of the oil separation core: If the oil separation core is damaged, such as damaged or perforated, its oil and gas separation function will fail, resulting in a large amount of cooling oil not being separated and discharged together with the gas.
The working status of the oil return pipeline: If the oil return pipeline is blocked, broken or incorrectly installed, the oil accumulated at the bottom of the oil separation core cannot be transported back to the compressor, resulting in oil during the exhaust process.
Control of system pressure: If the system pressure control is too low, the centrifugal force in the separator will be less than the centrifugal force required by the work, making the oil and gas separation incomplete.
The amount of cooling oil added in the compressor: If the cooling oil added is too much and exceeds the range of the compressor, the gas will involve the excess cooling oil in the gas discharge, resulting in excessive oil content in the discharge gas.
how to reduce the exhaust oil content:
regularly check and maintain the oil separation core and oil return pipeline to ensure that they are in good working condition.
Reasonably control the system pressure to avoid the adverse effects of too low or too high pressure on oil and gas separation.
In strict accordance with the requirements of the compressor to add the right amount of cooling oil, to avoid too much or too little oil on the exhaust oil content.
In general, the exhaust oil content of the micro-oil screw air compressor is a complex and important indicator, which is affected by many factors. In order to ensure the normal operation of the air compressor and the safety of subsequent equipment, it is necessary to regularly inspect and maintain the air compressor, and strictly control various operating parameters.
shanghai granklin group is a professional engaged in "water lubricated air compressor" manufacturer. They have successfully developed a variety of special gas compressors, such as gasoline gas compressors, nitrogen compressors, oxygen compressors, carbon dioxide
General air compressor pressure is how much depends on its type, specifications and the use of the environment. The following are some common air compressor pressure ranges: Low pressure air compressor: The working pressure is usually between 0.7 and 1.2 MPa (MPa), that is, 7 to 12 bar. Medium pressure
Scroll compressors and screw compressors have their own advantages and disadvantages, and the choice of which is better depends on the specific application needs and scenarios. Scroll compressor: Advantages: compact structure, stable operation, low noise, high energy efficiency, and can still maintain a relatively high level of partial load
Explosion-proof air compressor usually refers to the whole machine explosion-proof, that is, including motors, pipes, containers and other components are required to meet the explosion-proof standards, not just the motor explosion-proof. The following is a detailed explanation of explosion-proof air compressor: the definition of 1. explosion-proof air compressor explosion-proof air compressor is applied to equipment
The replacement cycle of the filter element of the air compressor pipeline filter is a problem that needs to be flexibly judged according to the actual situation. Generally speaking, a good air compressor pipe filter can be used continuously for 1500-2000 hours, but the specific replacement time still needs to consider the following factors: 1.
The hospital is a place with very high requirements for air quality. The use of compressed air in the hospital is much more extensive than most people think, and it runs through almost all aspects of diagnosis and treatment, surgery, nursing, and logistics.
The power and pipe size of the air compressor should be considered according to the actual gas consumption and work requirements. Here are some basic steps and recommendations: Determine gas consumption Calculate total gas demand: First, estimate or measure the total gas demand of all gas-using equipment, usually based on
Oil-free air compressor, as the name suggests, is a compressor that does not require oil lubrication during operation. This kind of compressor is widely used in various scenarios where a gas source is required but oil pollution is required to be avoided. The following are its main uses and features: provide clean
Oil-free screw air compressor, as the name suggests, refers to the screw air compressor that does not use lubricating oil for lubrication during its operation. However, this does not mean that the oil-free screw air compressor does not need any lubrication at all. In fact, the lubrication method of oil-free screw air compressor and
In the manufacturing process of cement products, whether an air compressor is needed depends on the specific production process and equipment requirements. However, from a general point of view, air compressors do play an important role in the manufacture of cement products. The manufacture of cement products usually involves a series
