The correct choice of electroplating industrial cold water machine
First of all we want to know in the water chiller according to the cooling mode is divided into water-cooled and air-cooled, but according to the structure can be divided into open and closed type, finally according to the compressor consists of screw type, vortex type, centrifugal type and piston type chiller.
Secondly, we must determine the cooling capacity of the chiller must be greater than the amount of heat generated in the electroplating process, so that the tank can be cooled. And we know the solution of the plating tank is sulfuric acid solution, to prevent corrosion of refrigeration equipment, is equipped with corrosion resistance to heat exchanger coil in the plating tank, cold water machine out of the frozen water enters the heat exchanger coil corrosion, and by the groove of the acid liquid for heat exchange, cooling away slot solution the heat to cool. If in the plating tank is placed in corrosion resistant heat exchanger, in the groove can be arranged outside a corrosion resistant water heat exchanger, the side walk chilled water walking electroplating solution.
If the acid liquid directly into the cold water machine, the direct cooling method, the heat exchanger inside the cold water heater must be made of corrosion-resistant materials, its cost is higher than the general cold water machine. So in understanding of the advantages and disadvantages, we should according to the actual situation to determine the need for cooling, and then choose the chiller.
The role of electroplating cold water machine:
Electroplating process in the production of electroplating bath solution to produce heat accumulation, the solution temperature increases, the temperature of the solution in the tank when the high technology requirements, the production of electroplating products surface coating fastness, evenness, smoothness and surface roughness has great influence. Therefore, it is required to use the chilled water cooler to cool the solution in the bath and keep the temperature of the solution in the plating bath to be constant.
