Core Technical Measures of Air Compressor to Ensure No Water
compressed air will carry a large amount of water vapor due to the increase in temperature during the compression process, and it is easy to condense into liquid water after cooling. To ensure a dry gas output, the moisture is controlled by the following steps:
cooling: through after cooler(Air cooling/water cooling) The high-temperature compressed air is rapidly cooled to ambient temperature, which promotes the condensation of water vapor into liquid water.
Mechanical drainage: Install at the low point of gas storage tank and pipeline automatic drain valve, Timed discharge of condensate (such as electronic timing valve or float drain).
principle: The use of silica gel, activated alumina and other desiccant adsorption of moisture, two towers work alternately to achieve continuous dehumidification.
Effect: The pressure dew point can reach below -40 ℃ (suitable for high clean scenes, such as food and electronics).
fine filter: Configure after dryer 0.01μm oil-water separator, intercept residual liquid water and oil mist.
dew point detection: Install online dew point meter to monitor the water content of compressed air in real time to ensure compliance with ISO 8573-1 standard (such as Class 4 dew point ≤ 7 ℃).
replace the desiccant (adsorption dryer every 2-3 years).
Clean the condenser (refrigerated dryer once a month).
Verify drain valve function (quarterly).
Through the above measures, the problem of moisture in compressed air can be systematically solved to ensure the safety and quality of downstream equipment or processes.
When there is water in the air compressor pipeline, the following measures can be taken to deal with it: 1. confirm the cause of water production First, it is necessary to clarify the cause of water production in the pipeline so that targeted measures can be taken. Common causes include water vapor condensation due to insufficient cooling of the air compressor,
Q: How much air compressor is used in the factory? A: If you don't know how much flow of compressed air the factory needs, you can consult the supplier of your production equipment first, they will have an accurate flow rate. In assessing whether other aspects
There are many kinds of gases used in the production of rubber and plastic industry, such as oxygen, nitrogen and compressed air. Compressed air is involved in all aspects of production in the rubber and plastic industry. Compressed air is required to participate in raw material processing, rubber extrusion, rubber molding, etc.
Screw air compressors are not suitable for frequent starting. The following is a detailed analysis of this problem: Large starting current: The screw air compressor requires a larger current when starting. Frequent starting and stopping will cause the motor to repeatedly withstand large starting currents, which may lead
Factory compressed air pressure requirements need to be determined according to specific application scenarios and equipment requirements. Granklin water lubricated screw air compressor can provide a wide pressure range of 0.3MPa to 4MPa to meet the needs of different industries. The following are from the conventional pressure range, special scenario requirements and
Whether the air compressor room needs anti-explosion or not involves many considerations. The following is a detailed analysis of this problem: Risk analysis of 1. air compressor room Explosion risk: During the operation of the air compressor, if the operation is improper Or the equipment is defective, it is possible
The air compressor belongs to the general mechanical type. The air compressor (English: air compressor) is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy.
First of all, we need to clarify the meaning of "kilogram" in the pressure unit. Here, "kilogram" actually refers to "kilogram force/square centimeter" (kgf/cm²), which is a commonly used unit of pressure, especially in a certain
With the rapid development of industry and the gradual improvement of people's living standards, the requirements of the society for the required products have been greatly improved. At the same time, the upgrading of the air compression system has promoted the oil content, water content, and decibels of the compressed gas. The requirements are getting higher and higher. Air compressor plant
Permanent magnet variable frequency screw air compressor: the preferred scheme of high efficiency, energy saving and stable operation 1. core advantages analysis of high efficiency and energy saving, reduce operating costs. Permanent magnet variable frequency screw air compressor through intelligent adjustment of motor speed, accurate matching of gas demand, to avoid the traditional air compressor"
