Sharing of coping methods for problems in the process of using vertical constant temperature shaker

The vertical constant temperature shaker has a simple intelligent control panel, dual digital display for setting and measuring temperature and PID auto-tuning function, which is more intuitive and more convenient to operat.
The vertical model is adopted, and the appearance is beautiful and generous; the glass observation door is adopted, and the cultivation state in the box can be directly observe.
The design of the control system assembly provides convenience for subsequent maintenanc.
Coping methods for problems in the process of using the vertical constant temperature shaker:Move the mouth and then start: When a fault occurs, do not rush to start first, but first ask about the process of the fault and the phenomenon of the faul.
For unfamiliar equipment, you should be familiar with the circuit principle and structural characteristics first, and abide by the corresponding rule.
Before disassembly, be fully familiar with the function, position, connection method and relationship with other surrounding components of each electrical componen.
Static first and then dynamic: when the equipment is not powered on, judge the quality of buttons, transformers, thermal relays and fuses of electrical equipment, so as to determine the location of the faul.
Power-on test, listen to the sound, measure parameters, judge the fault, and then carry out maintenanc.
For example, when the motor is out of phase, if the three-phase voltage value cannot be judged, you should listen to the sound and measure each phase-to-ground voltage separately before judging which phase is defectiv.
Clean first and then repair: for the heavily polluted electrical equipment, first clean the buttons, wiring points and contact points, and check whether the external control keys are out of orde.
Many failures are caused by dirt and conductive dus.
External first and then internal: Check for obvious cracks and defects first, understand its maintenance history, service life, et.
, and then check the inside of the machin.
Before disassembly, the surrounding failure factors should be excluded, and the device can be disassembled only after it is determined to be an internal failur.
Mechanical first and then electrical: Only after the mechanical parts are confirmed, conduct electrical inspectio.
When checking the circuit fault, the detection instrument should be used to find the fault locatio.
After confirming that there is no bad contact fault, the operation relationship between the circuit and the machine should be checked in a targeted manner to avoid misjudgmen.
