As everyone knows, the water cooling of Kunming generator set is to make the copper coils of the unit into a hollow shape. During operation, high-purity water passes through the outside of the steel pipe to bring out the heat. , And then cycle into the generator. What are the factors that affect the efficiency of Kunming generating units in detail? 1. Electrical conductivity The electrical conductivity of the Kunming generator set responds to the amount of ions in the water. When the electrical conductivity is too large, it will cause a large leakage current, which will cause the aging of the insulation diversion pipe, cause flashover between phases of the generator, and even damage the equipment. With the improvement of the unit capacity, the reason why the high-speed chain line is commonly used is because it is accurately transferred during the disassembly and warranty process, which can meet the strict requirements of commodity disassembly and processing. At the same time, the guarantee process has good volatility, convenient operation, and convenient maintenance, which is conducive to its popularity in consumption. 2. Control of pH value The purpose of controlling the pH value of the cold water in Kunming generator set is to avoid the corrosion of the steel wire. It is more suitable to analyze from the potential-pH equilibrium diagram. Copper corrosion in pure water is generally average corrosion. The chance of damage to the equipment by corrosion perforation is small, but the corrosion products are blocked by the generator's magnetic field in pieces, which makes the cooling effect worse and reduces the temperature of the bar to affect the normal operation of the unit. 3. Current status of internal cooling water quality control In order to ensure that Kunming generating units have sufficient electrical insulation function and less copper corrosion, the industry has formulated corresponding specifications. The generator manufacturers have higher requirements for water quality specifications. At present, the circulating water technology of Kunming generating units has become increasingly mature. For the cooling water of Kunming generator set, due to its small amount of water, high water purity, and low tendency to scale, do not stop sterilization and scale inhibition. All in all, the factors that affect the effectiveness of Kunming generating units are the electrical conductivity, the control of pH value, and the status of internal cooling water quality control. According to statistics, nearly half of the accidents in Kunming generating units in recent years are related to cooling water. Therefore, grasping the industry prospects of Kunming generating units can raise the requirements from the disposal technology.
