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:
the moisture content in compressed air is usually expressed in "dew point temperature. The lower the dew point temperature, the drier the air; on the contrary, the higher the dew point temperature, the more moisture in the air. When the compressed air is cooled to the dew point temperature, the moisture in it will begin to condense into liquid water.
general industrial scenario(e. g. machinery manufacturing, textiles):
the requirement for the dryness of compressed air is relatively low, and the dew point temperature is usually controlled above 0 ℃, mainly to avoid corrosion caused by the accumulation of condensed water in the pipeline or affect the operation of the equipment.
Precision Manufacturing and Electronics Industry:
more dry compressed air is required, and the dew point temperature is usually below -20°C to prevent moisture from causing corrosion or short circuits to precision components (such as chips and sensors).
Pharmaceutical and Food Industry:
the cleanliness and dryness of compressed air are required to be extremely high, and the dew point temperature should be controlled below -40 ℃ to ensure that there is no moisture in the air to avoid contamination of the product or affect the aseptic requirements of the production environment.
in order to meet the standards of different scenarios, drying equipment is usually installed at the rear end of the air compressor:
Through proper selection of drying equipment and regular maintenance, it is ensured that the moisture content of the compressed air continues to meet the requirements of the application.
The replacement cycle of the air filter (air filter) of the screw air compressor depends on the use environment and working conditions of the equipment. The following are some general suggestions on the replacement cycle of the air filter of the screw air compressor: the running-in period of the new machine: the newly purchased screw air compressor is running for about 500
Air compressors, cold dryers and dryers play an important role in the compressed air system, and they are closely related and complement each other. The following is a detailed analysis of the relationship between the three: 1. equipment function air compressor: definition: air compressor is a kind
At present, many industries continue to purchase air compressors, which is mainly due to the wide application of air compressors as important industrial equipment and their indispensable role in many production links. The following are some of the main industries that continue to buy air compressors: Machinery Manufacturing: On-machine
Take a look at it every day, check it every week, and do physical examination every month. The water lubricated air compressor should pay more attention to the water circulation and water quality at this rhythm. The overall inspection burden is lighter than that of traditional machines.
Frequency conversion screw air compressor and power frequency air compressor are two common compressed air equipment in the industrial field, each of which has different characteristics and application scenarios. The following is a detailed comparison of these two air compressors: 1. working principle of variable frequency screw air pressure
The pressure of the air compressor usually varies according to its type, specification and usage scenario. The following is a summary of the pressure range of different types of air compressors: 1. common air compressor pressure range low pressure air compressor: the working pressure of this type of air compressor
Q: Can the screw air compressor work continuously? A: Yes. The "water-lubricated oil-free screw air compressor" produced by Shanghai Granklin (Group) can be operated for a long time. When the pressure reaches the air compressor will automatically stop (permanent magnet
The displacement on the nameplate of the air compressor (usually marked as "volume flow" or "displacement") is the core parameter reflecting the performance of the air compressor. Its definition, unit and importance are as follows: 1. Definition Displacement refers to the specific import state (standard work
In the sterile supply room, compressed air is widely used in a variety of equipment to ensure thorough cleaning, disinfection and drying of medical equipment, thereby improving medical quality and safety. The following are some of the specific use of compressed air gas equipment: 1. automatic cleaning machine should be
If the filter element is not replaced during air compressor maintenance, the following situations may occur: Affect the performance of the air compressor: The main function of the filter element is to filter impurities in the air to ensure that the air entering the air compressor is pure. If the filter element is not replaced for a long time, it will cause blockage and cause
