The detection of water content in the air of air compressor should be carried out according to national standards or industry standards. In general, the standard GB/T3853-2018 "Technical Conditions for Air Compressors" stipulates that the saturated water content of compressed air is 30 mg/m & sup3 when the relative humidity is 100 at 30 ℃; Under the standard gas volume system, the mass flow rate of the open package shall not exceed about 0.1 mg/m & sup3; The amount of moisture. Air compressors used in specific industries should also be tested according to the industry's standards.
In addition, the water content in the air outlet of the air compressor should not exceed 80ppm (water content per cubic meter of gas does not exceed 80 mg). Detection of water content in the air compressor, the general use of dew point meter or capillary method. Among them, the dew point meter has higher accuracy and can detect the water content of 0.001ppm, while the capillary method has a certain error in detecting the water content, but the operation is simple, and it can be considered for smaller air compressors.
In addition, air compressor oil water content standards usually vary according to different applications and industries. In general, the water content in air compressor oil should be less than 100ppm (I. e. 0.01%). In some special areas, such as food processing, pharmaceuticals, etc., the water in the air compressor oil is more demanding, generally requiring a water content of less than 20ppm (I. e. 0.002%).
Specific water content standards may vary by region, industry regulations or user requirements. Therefore, when selecting and using air compressors, it is best to refer to relevant industry standards, equipment manufacturer's recommendations or communicate with suppliers to ensure compliance with specific application requirements.
The drainage of oil-free air compressor is an important maintenance step. The following are detailed drainage steps and precautions: Turn off the power 1. manual drainage steps: Before performing any maintenance operations, first make sure that the air compressor has been turned off and cut off the power. To ensure safety.
The reasons why the air pressure of an oil-free air compressor cannot be increased may involve several aspects. First of all, we need to consider whether the air inlet of the air compressor is blocked. If the air inlet is blocked, the air flow will be restricted, resulting in no air pressure.
Two screw air compressors can supply air in series. The following is a detailed analysis of the series air supply of two screw air compressors: The feasibility of series air supply: The working principle of the screw air compressor enables it to adapt to the series air supply method. In a series configuration, the front
As an efficient, environmentally friendly and stable compression equipment, water-lubricated air compressor has received extensive attention and application in the market. Among many brands, the water-lubricated screw air compressor produced by Shanghai Granklin Group stands out for its excellent performance and reliability.
Air compressors, I .e. air compressors, usually belong to the category of industrial equipment or electromechanical equipment. In a more specific classification, it may be classified into subcategories such as pneumatic tools, compression equipment or industrial compressors. These classifications help users or purchasers in finding, purchasing, and
Micro-oil screw compressor and oil-injected screw compressor are two common types of screw air compressors, which are significantly different in lubrication mode, working principle, application scenario and maintenance requirements. The following are the specific differences between the two: 1. Lubrication methods and work
22 kW air compressor displacement analysis-take the water lubricated air compressor of Shanghai Greenlin Group as an example. In the air compressor market, 22 kW air compressors are favored by users because of their moderate power and wide range of application scenarios. This article
Air compressor is not special equipment. However, as long as the working pressure of the gas storage tank and the connected pipeline is greater than or equal to 0.1Mpa, the volume and the pipe diameter are greater than or equal to 25mm, it belongs to special equipment. Special equipment refers to the boiler, pressure capacity involving life safety and greater risk.
The main difference between oil-free compressed air and oil-free compressed air is whether lubricating oil is used in the compression process. The following is a specific comparison: Use of lubricating oil: Oil compressed air: During the compression process, lubricating oil is needed to lubricate the inside of the compressor
The slow air output of the air compressor may be caused by a variety of factors. The following are several common reasons and solutions: Common reasons for poor valve sealing. Explanation: During the operation of the air compressor, the long-term repetitive impact of the valve plate makes it match the sealing surface. Wear, causing low-pressure cylinder
