a、 During the debugging process, if the temperature cannot be reduced, the main consideration is that the water quality is not clean. Rust and particulate matter will block the water supply control valve and nozzle, and the cooling water cannot be sprayed into the steam pipeline. Clean the water supply control valve and nozzle (remove them), or use compressed air to blow back and wash the particles clean.
b、 During operation, if the temperature cannot be reduced, the main consideration is whether the water quality is softened water or if the softening does not meet the standard, resulting in clogging of the small holes (nozzles) and the water supply control valve. Clean the water supply control valve and nozzle with hydrochloric acid (disassembled).
c、 The cooling water pump is malfunctioning or the cooling water pressure is too low.
