How to solve the problem of increased equipment wear caused by unstable stirring speed of stock solution preparation system?

Find out the reasons for unstable stirring speed:
1. Electrical system failure: Check whether the power supply voltage and current of the motor are stable, whether there are problems such as phase loss and short circuit; check whether the controller, inverter and other components of the motor are working normally and whether the parameters are set correctly; check whether the circuit connection is loose and the contact is poor. For example, fluctuations in the power supply voltage may cause unstable motor speed, which can be solved by installing a voltage stabilizer.
2. Mechanical component failure: Check whether the stirring shaft is bent, deformed or worn, whether the stirring paddle is loose, damaged or unbalanced, and whether the transmission parts (such as belts, chains, gears, etc.) are worn, slipped or loose. For example, wear of the stirring shaft will cause changes in the stirring radius, thereby affecting the stirring speed and effect, and the stirring shaft needs to be replaced in time.
3. Material factors: The properties of the material (such as viscosity, density, particle size, etc.) may affect the resistance to stirring, resulting in unstable stirring speed. For example, high-viscosity materials require greater stirring force to achieve the same stirring effect. If the motor power is insufficient, it may cause the stirring speed to decrease. In addition, the feeding speed and uniformity of the material will also affect the stirring speed. If the feed speed is too fast or uneven, the stirring paddle may be overloaded instantly, thus affecting the stability of the stirring speed. Therefore, it is necessary to select appropriate stirring equipment and process parameters according to the characteristics of the material, while ensuring the feeding speed and uniformity of the material.
4. Equipment installation problems: Check whether the installation foundation of the stock solution preparation system is firm and whether there is vibration or tilt; check whether the installation position of the stirring equipment is correct and whether there is interference with other equipment or pipelines. For example, if the equipment is not installed horizontally, the stirring shaft will be unevenly stressed, which will accelerate the wear of the equipment and the installation level of the equipment needs to be readjusted.
Take corresponding solutions for different reasons:
1. Repair or replace electrical components: If there is a fault in the electrical system, it needs to be repaired by a professional electrician or maintenance personnel. Damaged motors, controllers, inverters and other components should be replaced in time; loose or poorly contacted circuit connections should be tightened and repaired. In addition, it is also possible to consider upgrading or modifying the electrical system to improve the performance and stability of the equipment. For example, adopt more advanced motor control technology or install an intelligent monitoring system to monitor and adjust the stirring speed in real time.
2. Repair or replace mechanical parts: For worn, damaged or deformed mechanical parts, they should be repaired or replaced in time. For example, the wear of the stirring shaft can be repaired by brush plating, thermal spraying, surfacing and other processes, or a new stirring shaft can be directly replaced; the loose stirring paddle can be tightened or replaced; the worn transmission parts can be replaced or the tension can be adjusted. In addition, the mechanical parts can be optimized to improve their wear resistance and reliability. For example, use better quality materials, improve the structure and manufacturing process of the parts, etc.
3. Optimize material handling: If the nature of the material causes the stirring speed to be unstable, some measures can be taken to optimize the material handling. For example, for high-viscosity materials, the stirring temperature can be appropriately increased to reduce the viscosity of the material; for materials containing large particles or impurities, pretreatment such as screening, crushing, etc. can be carried out to reduce the stirring resistance. At the same time, the feeding speed and uniformity of the material should be controlled to avoid the influence of too fast or uneven feeding on the stirring speed. Suitable feeding devices and conveying equipment, such as screw feeders, belt conveyors, etc., can be used, and the feeding speed can be adjusted according to the characteristics of the material and the stirring requirements.
4. Reinstall or adjust the equipment: If there is a problem with the equipment installation, it needs to be reinstalled or adjusted. For example, the installation foundation should be reinforced or repaired to ensure that the equipment is firmly installed; the installation position of the mixing equipment should be adjusted to avoid interference with other equipment or pipelines; the equipment should be horizontally adjusted to ensure the verticality and concentricity of the mixing shaft. In addition, the supporting structure and shock absorbing device of the equipment can be inspected and maintained to reduce the vibration and noise of the equipment.
