Explanation of calibration of automatic sampler

The sampler is designed to be maintenance-free. It can run for a long time without maintenance and is not easily blocked by waste fuses, detonating tubes and woven bag mesh and other impurities, and does not leak. The following is aboutautomatic samplerAn explanation of the calibration process.

After the automatic sampler is installed, the wiring is connected according to the wiring requirements and there are no problems, the equipment can be calibrated and commissioned. For manual turning, the sampling spoon should be simply adjusted to the middle position, and then the power supply is turned on. Turn on the main switch. At this time, the indicator light will be on. Place the PLC program-controlled power switch in the RUN position. After 10 seconds, the motor will run. At this time, the sampling spoon should run away from the transmission mechanism (motor), or a person should stand on the side of the motor to observe whether the motor should Run counterclockwise, otherwise, interchange the two cables connected to the motor. When adjusting the motor wiring, you must wait for 5 minutes after the power is turned off and the inverter indicator light goes out before you can proceed with the position adjustment. After it is completed, it can be put into trial operation. When the sampling spoon rotates to one side, its parking position should be in the gap outside the sampling area to ensure that no coal slurry is added after the sampling spoon reaches one side. It can be adjusted according to the installation position of the sensor. The docking position of the sampling spoon, the vertical position of the sensor and the control panel should be between 2-4mm.
