The production of graphite cooler is not a simple and easy thing, it needs many processes. What are the conditions and requirements for the production of graphite cooler to achieve a good graphite cooler equipment.
The first thing to ensure is the safe production of graphite cooler. When the graphite cooler stops working, the first thing to do is to safely close the water inlet valve of the graphite cooler for a period of time and then completely cut off the power switch of the pump and fan to stop the water supply. In winter and other seasons, horizontal and combined graphite coolers should be drained. If the graphite cooler is not working for a long time, drain the refrigerant and cut off the connection with other pipes.
If the graphite cooler equipment is running, check the openness of all piping and related valves, including the inlet valve, outlet valve, inlet valve, outlet valve, equalizer valve, shut-off valve in front of the safety check valve, and the valve of the liquid level indicator. At this time, the drain valve and air vent valve should be closed. In the case of production, it should be noted that the condensing pressure generally does not exceed 1.5Mpa. For ammonia compressors, the cooling water should be tested regularly for ammonia by chemical analysis to determine whether the graphite cooler will leak ammonia. It needs to be checked once a month, so that even if problems are found, they can be dealt with in time.
Graphite cooler manufacturers believe that the graphite matrix is an excellent thermal conductor and corrosion resistant. It can resist almost all acids, alkalis and high temperatures. However, some graphite capacitors are alkali resistant due to impregnation limitations, while others have other limitations. One may ask if it is possible to use a graphite matrix instead of impregnation as a condenser? This question starts with the formation of graphite. The graphite typically used as a structural material for equipment is manufactured graphite, and the raw materials are primarily petroleum coke, anthracite and coke. There are two key processes in graphite forming, one is high temperature roasting and the other is graphitization. Both processes are carried out at a temperature of two to three thousand degrees, which contains a large amount of water, the ash is evaporated, and then the graphite material formed has certain pores. Obviously, this material is not suitable for the structure material of condenser, so it is filled with impregnant to make it impermeable material, so it can be used as condenser.
Graphite cooler manufacturers believe that the water-cooled condenser mainly uses water as the cooling medium, and takes away the condensation heat of the system through the temperature rise of the cooling water. Cooling water is circulated in the system, so the cooling system should be equipped with cooling facilities such as cooling towers or cooling pools. According to the different structure of water-cooled condenser, it can be divided into shell and tube condenser and casing condenser, of which the shell and tube condenser has a relatively wider range of applications.
The above is about graphite cooler some knowledge points, I hope you can seriously learn to understand the relevant knowledge, choose the right products and equipment for their needs, to ensure their own benefits, if you want to know more details, you can contact us, I believe that we can certainly give you a satisfactory answer.
