Compressed air can be pressurized, cooling, adsorption and other methods to remove the water vapor, and can be through heating, filtration, mechanical separation and other methods to remove liquid moisture.
Refrigerated dryer is a kind of equipment that cools the compressed air to remove the water vapor contained in it and obtain relatively dry compressed air. The rear cooler of the air compressor also uses cooling to exclude the water vapor contained therein. Adsorption dryer is the use of adsorption principle to remove the water vapor contained in compressed air.
The cold dryer is based on the principle of freezing and dehumidification. The compressed air is forced to pass through the evaporator for heat exchange and cooling, so that the gaseous water and oil in the compressed air are cooled by isobaric cooling, condensed into liquid water and oil, and entrained with dust. The water is discharged out of the system to obtain clean compressed air.
Reasons for high evaporation temperature of cold dryer:
the evaporation temperature increases with the increase of the evaporation pressure. The reasons for the increase of evaporation pressure are:
① The load of the cold dryer exceeds the rated value;
the working pressure of compressed air is too low;
the temperature of compressed air entering the cold dryer is too high;
④There are problems with the refrigerant system, such as: too large opening of the expansion valve, too much refrigerant liquid charge, poor heat dissipation of the condenser, resulting in too high condensation pressure, etc;
⑤ There is a problem with the compressor. If the evaporation temperature is too high, the dew point of the compressed air will rise, resulting in the phenomenon of endless water removal and exhaust with water.
Oil-free air compressor does not need to add any lubricating oil, from the source to ensure that the discharge of compressed air does not contain oil and oil vapor, eliminating the risk of oil pollution to the air and end products, but also eliminating the possibility of increasing costs due to oil, is a green product. Compression
If the permanent magnet air compressor condensate is not discharged for a long time, it will cause rust inside the unit, reduce the effect of lubricating oil, and affect the operation of the air compressor. In summer, it will even cause the air compressor to start and stop constantly. So what is the basic principle of this air compressor?
The highly integrated, energy-efficient integrated mainframe produced by Shanghai Granklin Group comes from the Granklin Group Air Compressor Technology Research and Development Center. Water lubricated screw air compressor host, water vapor cylinder, water filter and air filter, intake valve, cold dryer, air storage tank, etc. are integrated into one, forming an integrated air compressor system. The built-in three filters are easy to maintain, and there is no pipeline loss inside. It takes up very little space and is the key first step to form a small lightweight air compressor; at the same time, it also provides enough maintenance space.
Select the air compressor manufacturer quotation, the first choice of qualified air compressor manufacturers, the factory in the after-sales service and technical support is not the same. Most large-scale projects such as chemical manufacturing and medical equipment production will choose to find "Shanghai Granklin Group" and communicate with sales and technical departments to adopt appropriate technical solutions.
View detailsThe wiring is as follows: 1. The three live wires of the air switch are respectively connected to the three inlet ends of the AC contactor of the air compressor, and the three outlet ends are respectively connected to the motor. 2. Any live wire is connected to the coil of a 380V AC contactor, and the other end of the coil is connected to the normally closed contact of the thermal relay.
In the case of permanent magnet variable frequency screw air compressor which is good to use (commonly used single-stage compression screw machine), the permanent magnet variable frequency air compressor is often unfamiliar with the equipment of permanent magnet variable frequency air compressor and does not know what brand of permanent magnet variable frequency compressor to choose.
How much is the price of Guangzhou air compressor and how much is the price of Guangzhou air compressor? A screw air compressor for decoration is used to determine the skills. Experienced teachers will determine the silent air compressor. This is also an effort to make money. The music of ordinary screw air compressor is very loud when working.
Oil-free air compressors are often used in production and life. Many companies will purchase them, but there are some parameters that need to be understood when purchasing. The precautions for choosing oil-free air compressors are as follows: 1: First of all, you must choose a truly oil-free air compressor. There are many types of oil-free air compressors on the market, but there are not many that can be completely oil-free, granklin water lubricated air compressor when running
There are many types of air compressors, and they are generally subconsciously divided into oil-free screw air compressors and oil-free air compressors. This two in addition to the lubricating oil method is not the same as what is not the same? Mentioned oil-free air compressor many people's first reaction is not oil,
To purchase air compressor products, first you have to learn to calculate an account, service life, after-sales air compressor, whether there is a manufacturer to provide technical support. It takes a long time to purchase an air compressor. If you spend hundreds of thousands of dollars to purchase the air compressor, it will take only 2 years to have various problems.
