UQKThe float level controller switch plays a key role in industrial production, accurately controlling the liquid level inside open or pressurized containers. It is necessary to develop a scientific and reasonable daily maintenance plan to ensure its stable operation and reduce the occurrence of faults.

Daily inspection: meticulous observation, prevention and control

Daily inspections are the foundation of maintenance. The operator needs to conduct a daily visual inspection of the controller switch to check for any deformation, damage, or jamming of the float ball. If the floating ball deforms, it will directly affect its accuracy in floating with the liquid level, leading to liquid level control errors. At the same time, check whether the connection parts are loose, including the connection between the float and the connecting rod, and the connection between the connecting rod and the housing. Loose connections may cause unstable signal transmission. In addition, pay attention to the surrounding environment of the controller to ensure that there is no accumulation of debris, and prevent debris from interfering with the movement of the floating ball or affecting signal transmission. If damage or signs of water ingress are found on the controller casing, it should be immediately stopped and further inspected to avoid damage to internal components.

Regular cleaning: remove dirt and ensure performance

In industrial environments, controller switches are prone to contamination with impurities such as dust and oil. Regular cleaning can effectively prevent these impurities from affecting the movement of the float and signal transmission. When cleaning, gently wipe the surface of the controller housing with a soft dry cloth to remove dust. For stubborn stains such as oil stains, you can dip a small amount of neutral cleaner to wipe them off, but be careful to avoid the cleaner from entering the interior of the controller. For the floating ball part, if it is contaminated with dirt, it can be rinsed with clean water, but after rinsing, it is necessary to ensure that the floating ball is completely dry before installation and use to prevent residual moisture from affecting its performance.

Electrical inspection: Ensure signal stability and reliability

Regular electrical inspections are key to ensuring the normal operation of the controller switch. Use a multimeter or other tools to check the contact resistance of the relay contacts, ensuring that they meet the requirements of the product manual. If the contact resistance is too high, it will cause poor signal transmission and affect liquid level control. At the same time, check the connection of the signal line to see if there is any looseness, damage, or short circuit. Poor connection of signal lines may cause signal interruption or misoperation, and it is necessary to tighten or replace the signal lines in a timely manner.

Recording and Analysis: Accumulate Data, Maintain Accurately

Establish and maintain a record file, detailing the situation of each inspection, cleaning, and electrical check, including the problems found, the measures taken, and the results of the handling. By analyzing these data, potential issues with the controller can be identified in a timely manner and maintenance plans can be developed in advance. For example, if it is found that the movement of the floating ball gradually becomes less flexible, it can be analyzed whether it is due to dirt accumulation or internal component wear, and targeted maintenance can be carried out accordingly.
