Abstract:The desuperheating water nozzle of refrigeration station was frequently blocked during operation. The nozzle was needed cleaning manually. The pressure&frequency of the pipeline transmitting pump was forced to open largely, and the power consumption also increased, which seriously affected the normal operation state of the refrigerating machine system. In allusion to above problems, we took a series of technical means including on-site system verification, water quality analysis, energy spectrum analysis of blocking matter, then we drew a preliminary conclusion and put forward correspondingly reasonable and effective prevention measures.
