How to troubleshoot and handle the malfunction of the Rotary Paddle level Switch? This is a necessary knowledge point for customers who have already used and want to use the Rotary Paddle level Switch.

As a simple and reliable on-site control device, the Rotary Paddle level Switch has unique sealing design, overload protection ability, and simple installation method. It is mainly used for measuring the level of solid materials (powder, particles) in industries such as feed, food, chemical, plastic, construction, fertilizer, etc. Although there are many characteristics, during long-term use, if the on-site working conditions are harsh or the installation and use are improper, the Rotary Paddle level Switch may also fail to function properly.

Exclusion method:

1. The Rotary Paddle level Switch is a material level measuring instrument that uses a micro motor as the driving device. In general, the motor is a crucial and easily consumable component of the Rotary Paddle type level Switch. Due to the importance of the motor to the Rotary Paddle level Switch, it is just as important as the heart to humans. So if the quality of the motor is average or even poor, it will undoubtedly shorten the lifespan of the Rotary Paddle level Switch.

When the Rotary Paddle Switch malfunctions, the first step is to open the junction box of the Rotary Paddle level Switch, remove the power socket, and power on to observe whether the motor operates normally. Usually, if the main shaft does not rotate or the motor makes abnormal noise when the main shaft is idling, it indicates that the motor has malfunctioned. The solution to this problem is to contact the manufacturer to replace the motor with a new one.

Because motors are very important for Rotary Paddle level Switch, it is recommended that users choose Rotary Paddle type level Switches equipped with high-quality, reliable, and long service life motors when purchasing Rotary Paddle level Switches, instead of blindly pursuing low prices and losing everything.

To ensure the reliability of the product from the root, the Rotary Paddle Switch adopts imported motors, micro switches, and bearings. At the same time, it pays attention to process details, strictly controls production processes and quality testing, and has higher reliability than similar domestic products.

2. If the motor operates normally after investigation, the switch output signal should be observed for abnormalities. If the switch output signal switches normally, it can be ruled out that the circuit board is damaged; If the switch output signal switches abnormally, it can be determined that the circuit board itself is damaged, and instrument maintenance personnel should be contacted to send it to the factory for repair.

3. If the spindle is stuck, it should be checked to see if the matching dimensions between the spindle and the components on the spindle are correct. In general, when the spindle is stuck, the rotating paddle switch will cause the spindle to idle and accompanied by abnormal noise, which can easily cause false alarms and even reduce the lifespan of the instrument. To solve this problem, the manufacturer is required to select components with the correct size and assemble them strictly according to the requirements of the process documents to ensure sufficient lubrication of the components.

4.      If, after the above investigation, it is found that the instrument itself is not abnormal, then it should be checked whether the on-site installation of the Rotary Paddle level Switch is reasonable. Firstly, check whether the aperture size of the installation bottom plate is appropriate, secondly, check whether the installation short pipe is concentric with the opening position, and whether the bottom plate opening is reasonable.
