In the process of using a calorimeter to carry out experiments, the stable operation of the stirring device is crucial, which directly affects the accuracy of the experimental data. However, many users will encounter the problem of loose stirring of the calorimeter. If it is not checked and solved in time, it will not only interfere with the experimental process, but also lead to deviations in the experimental results. Below, we will systematically sort out the core reasons for the loose stirring of the calorimeter to help you quickly locate and solve the problem.

First, mechanical parts wear and age

The stirring device of the calorimeter is in continuous operation for a long time, and the core mechanical components such as the stirring shaft, bearings, and connecting gears will inevitably wear out. Especially when the equipment is used for a long time or is in a high-load operation state for a long time, the degree of wear of the components will continue to increase. For example, after the bearing is worn, the concentricity of the stirring shaft will decrease, and the shaking will occur during operation, which will cause the stirring to loosen. In addition, the tooth surface of the connecting gear is worn, which will cause the gear to not mesh tightly, making the power transmission of the stirring device unstable, resulting in loosening and slipping.

Second, there are omissions in the installation process

The degree of standardization of the installation link directly determines the initial stability of the stirring device. During the installation process of the equipment, if there is a deviation in the installation position of the stirring shaft and the levelness and verticality are not strictly calibrated, the force of the stirring device will be uneven during operation, and it will loosen after long-term operation. At the same time, if the screws and nuts of each connection part are not tightened according to the standard torque, the screws and nuts will gradually loosen under the action of vibration generated by the operation of the equipment, which will then cause the overall loosening of the stirring device. In addition, if there is an error in the installation angle of the stirring blade and the stirring shaft during installation, it will also lead to an imbalance in the force during stirring and accelerate the loosening of the

Third, the influence of external vibration interference

If there is a strong external vibration in the working environment of the calorimeter, it will have a serious impact on the stability of the mixing device. For example, if the equipment is placed on an unfixed and stable table surface, or there is a large-scale running equipment around to generate continuous vibration, these vibrations will be transmitted to the calorimeter through the table surface, resulting in displacement of the fixed parts of the stirring device, which in turn will cause loosening. In addition, if the shock absorption device of the equipment itself fails, it cannot effectively counteract the vibration generated by operation, which will also cause the vibration to accumulate and exacerbate the looseness of the stirring device.

IV. Lack of daily maintenance work

Inadequate daily maintenance is one of the important causes of loosening of stirring. If the stirring device is not cleaned for a long time, dust, oil and other impurities will accumulate on the surface of the parts, which will not only exacerbate the wear of the parts, but also cause the connection parts to get stuck, affecting the normal operation of the stirring device, and then causing loosening. At the same time, if the key components such as fixing screws and bearings of the stirring device are not regularly checked and tightened, these parts will gradually loosen under the action of vibration generated by the operation of the equipment, eventually leading to the loosening of the stirring device as a whole. In addition, the lack of lubrication and maintenance of the stirring device will increase the operating resistance of the parts, accelerate wear, shorten the service life of the parts, and increase the risk

V. Component quality and adaptability issues

If the quality of the parts of the stirring device of some calorimeters is not up to standard or the adaptability is poor, it is also easy to cause loosening problems. For example, the size of the purchased replacement parts does not match the equipment, and it cannot be tightly fitted after installation, which is prone to loosening during operation. In addition, if the material strength of the parts is not enough to withstand the load of the equipment during operation, the parts will be deformed and cracked during long-term operation, which will lead to loosening of the stirring device.

In response to the problem of stirring loosening of the calorimeter, users can first investigate the above aspects one by one. After accurately locating the cause, they can take measures such as replacing worn parts, recalibrating installation, strengthening shock absorption, and improving maintenance procedures in a timely manner. In daily use, it is necessary to pay attention to the daily maintenance and regular maintenance of the equipment, and standardize the operation process in order to effectively reduce the probability of stirring loosening problems, ensure the stable operation of the calorimeter, and ensure the accuracy of experimental data.
