Refrigeration failure of the high and low temperature test chamber
.
Which methods should be mastered? The analysis is summarized as follows: first look, second listen, third touch plus analysis
.
One look means to check the values of various instruments and meters of the high and low temperature test box, such as oil pressure, temperature, current, etc.
, to check the equipment operation and maintenance records, to check the frost or condensation on the surface of the suction pipe and the evaporator, etc.
.
The second listening refers to listening to the sound of the compressor of the high and low temperature test chamber running, listening to the flow of the refrigerant in the expansion valve, and listening to the management personnel's response to the operation of the equipment and abnormal phenomena
.
The third touch is to touch the temperature of the system pipeline and related components, as well as the vibration of the high and low temperature test chamber equipment during operation
.
