Condensed water is a big killer of air compressor. If it is not discharged in time, it will rust the inside of the unit, reduce the performance of lubricating oil and affect the operation of the unit. So how is the condensate produced? And how to discharge?
Air compressor condensate water mainly comes from the air. The air sucked by the air compressor contains moisture. These gases containing moisture enter the unit. As the operating temperature of the unit rises, these moisture will evaporate. The evaporated moisture will enter the air storage tank for cooling with the compressed air. Many liquid water, we call it condensed water. If the air humidity is higher in the rainy season, the more condensed water will be.
Secondly, the low temperature operation of the air compressor will also produce condensed water. The operating temperature of the unit is lower than the moisture evaporation temperature, which will cause the moisture in the air to be directly precipitated to form condensed water. Therefore, long time low temperature operation of the machine should be avoided.
The discharge time of condensate is not clearly defined. It is usually based on the unit's intake air humidity and operating conditions. Usually the user will be in the boot or shut down, the condensate is fully precipitated, so that it will not affect the normal use of the unit can also ensure the effect of drainage.
Drainage shall be carried out after the air compressor is shut down, there is no pressure in the oil and gas separation tank, and the condensed water is fully precipitated. General air compressor will be equipped with a gas storage tank, at the bottom of the gas storage tank will be equipped with a drain valve, open the valve can drain. In order to facilitate the discharge of condensed water, most users will install automatic drainers. The automatic drain will handle the closed state without pressure. When the condensed water reaches a certain amount, the drain will automatically open. The water will be discharged under the action of air pressure. At the same time, the buoyancy will decrease and the air bottle will drop to block the drain.
Air compressors themselves are not directly classified as dangerous goods. It is a commonly used mechanical equipment, mainly used to compress and store air, and provide power source for various pneumatic tools, equipment and systems. However, when using air compressors, it is necessary to follow certain safety
Air compressor motor is one of the important parts of the air compressor, but customers are often easy to ignore its importance, routine maintenance will always lack of "care" for it ". How to properly maintain the air compressor motor? Today, I 'd like to introduce you to the motor dimension.
The use efficiency of industrial air compressors is usually between 60% and 90%, and the specific value depends on factors such as model, technology, operating conditions and maintenance status.
The compressor does not belong to, and the air storage tank matched with the air compressor belongs. Compressor dynamic equipment does not belong to special equipment, but 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 pipe diameter are greater than or equal to 25mm, it belongs to special equipment. If you are
The design service life of the air storage tank pressure vessel is mainly affected by a number of factors, the following is a detailed summary and analysis of these factors: design life and standards: the air storage tank in the design stage will be based on the design standards and specifications to determine a set.
The water content standard of compressed air varies according to the application scenario. The core is to control the moisture content in the air to avoid adverse effects on equipment, products or processes. The following is a brief description of the relevant standards: Key indicators of water content: dew point temperature Moisture in compressed air
Whether the compressed air tank belongs to special equipment depends on its design pressure and volume. According to publicly released information, only industrial compressed air tanks with a design pressure greater than 0.1MPa are regarded as special equipment and need to be managed in accordance with specific laws and regulations.
Air compressors are used in a wide range of applications: steel, electric power, metallurgy, shipbuilding, electronics, textile, mining, chemical, petroleum, light industry, papermaking, printing, machinery manufacturing, food, medicine
The replacement cycle of the lubricating oil of the new screw air compressor is affected by the type of lubricating oil, the working environment and the frequency of use. The following is a detailed guide: 1. the first oil change cycle, the running-in period of the new machine: it is recommended to replace the first lubricating oil after 500 hours of operation to remove the initial oil.
Air compressor is a kind of equipment widely used in various industries. Its main function is to compress and store air so as to supply other equipment or processes. Different types of air compressor, the pressure range is also different. The following is a common type of air compressor pressure range
