AI Technical Summary
Traditional heat exchanger performance testing devices are prone to water leakage when measuring water pressure, which affects accuracy and makes it impossible to detect leaks on the outer wall in time, resulting in low measurement efficiency.
A heat exchanger performance testing bench was designed. By setting up a support frame, connecting pipe, water injection pipe, measuring cylinder and break switch on the testing bench, the break switch is automatically disengaged and an alarm is issued when the water pressure changes by using a reset spring and a drive plate, so as to detect leaks in time. The heat exchanger is fixed by a rotating plate and a rotating rod to ensure the accuracy of the measurement.
This technology enables timely alarms when the pressure inside the heat exchanger decreases, avoiding multiple measurements, improving measurement accuracy and efficiency, and ensuring timely detection of leaks on the outer wall.
