The rotary high-capacity constant temperature oscillator may encounter some common faults during use. The following summarizes the main problems and corresponding solutions:
1. Abnormal temperature
Performance: The set temperature cannot be reached, or the temperature fluctuates greatly.
Possible reasons:
Malfunction of cooling/heating elements in the constant temperature system
Damaged or improperly positioned temperature sensor
Unreasonable controller parameter settings
resolvent:
Check if the heating tube and cooling unit are working properly
Calibrate or replace temperature sensor
Adjust PID control parameters to ensure stable temperature control
2. Unstable oscillation
Performance: Insufficient oscillation amplitude or occurrence of pauses/irregular movements during the oscillation process
Possible reasons:
Wear of drive motor or transmission mechanism
The oscillating tray is overloaded or unevenly placed
Abnormal control circuit
resolvent:
Check and replace worn motors or gears
Adjust the sample placement to ensure even weight distribution
Check if the control circuit and power supply are functioning properly
3. Excessive noise
Performance: The noise during operation is significantly higher than the normal level
Possible reasons:
Oil shortage or wear of bearings or sliding components
Loose fixing bolts
resolvent:
Lubricate or replace bearings and moving parts
Check and tighten all connecting bolts
4. Slow cooling/heating speed
Performance: It takes too long to reach the set temperature
Possible reasons:
Poor circulation of coolant
Decreased cooling/heating efficiency
Insufficient or unqualified coolant
resolvent:
Check the coolant flow path and clean the pipeline
Add or replace coolant
Check the performance of heating or cooling modules
5. Abnormal display on the control panel
Performance: Screen not displaying or buttons malfunctioning
Possible reasons:
Control board malfunction
Loose or damaged wiring
resolvent:
Check the wiring and reconnect it
Replace the control panel if necessary
