With the development of modern industry, the emergence of powder coating equipment in the market has greatly accelerated and upgraded the industrial procedures of many chemical and material companies, but at the same time we cannot be careless about the use of coating equipment. How safe is the coating equipment?
①Everyone should do the oil filling and exhausting work of the system, and follow the operation procedures. Use the oil filling pump to input all the input oil storage tanks that need full amount into the whole system, supply the system after filling up, open the cold oil replacement valve and close it after exhausting. , When the oil is filled into the expansion tank, and the oil level rises beyond the overflow port and returns to the oil storage tank, the oil injection pump and the inlet and outlet oil valves must be closed.
②After the cold cycle exhaust, the dehydration and exhaust must be carried out in a step-by-step heating method, so as to further remove the remaining air, moisture and low-boiling vapors in the system, and increase the temperature at a rate of 20 °C per hour. 6 hours, if there is no abnormal situation, it will be heated to the temperature of use and put into normal use.
③During the process of heating up and normal use, it is necessary to carefully check the leakage of the whole system, because the porous thermal insulation material has the phenomenon of adsorption to the coating equipment, so it is necessary to check carefully and in-depth section by section, and strictly prevent the slightest leakage phenomenon. , to ensure its safety and not to be careless.
④In normal heating operation, a certain circulating flow should be maintained. Do not adjust the entire heat supply by reducing the circulating flow. Open the bypass valve at an appropriate time to reduce the furnace temperature and adjust the heat supply. In special circumstances, the furnace needs to be shut down, so the temperature of the equipment must be lowered before the pump can be turned off to stop the circulation. At this time, in order to speed up the cooling, the cold oil in the oil storage tank can be input into the system to replace the hot oil.
