What to do if there is a strange sound when using the kneading machine

When the heavy-duty kneading machine flows through the wall of the device and various fixed components installed in the container, it will also be subject to shearing. These shearing actions will cause many local eddy currents to diffuse. It is a new type of high-precision particle kneading machine. The kneading machine is sealed and dust-free, simple to operate, easy to maintain, and has a long service life. The combination of revolution and rotation in the kneading machine forms four flow forms of powder: convection, shear, diffusion, and infiltration.
The mixing, heat transfer, mass transfer (including devolatilization) and reaction of high-viscosity fluids in the kneading machine are one of the research topics of stirring technology in recent years. For low-viscosity liquids, the traditional propulsion, paddle, and turbine impellers can solve the problem. In the table, although the anchor and frame impellers cover a wide range of viscosities. However, as mentioned above, in the higher viscosity domain, the kneading effect of the anchor impeller is much worse than that of the spiral belt, and in the low viscosity domain, its shear stress is insufficient, the axial circulation is also poor, and because its paddle diameter is relatively large to the groove diameter.
During the use of the heavy-duty kneading machine, if the kneading machine in use makes an abnormal sound, it is very likely that there is a problem with the mechanical components on the kneading machine. It may be that the coupling between the pump and the motor is not on the same center line, so it is necessary to re-center the coupling between the pump and the motor. Or the coupling is loose or has problems, so it is necessary to reinforce the coupling or replace a new coupling.
If the shockproof device of the kneading machine is abnormal, it needs to be checked and reinforced. If this does not solve the problem, it is necessary to replace the new part. It may also be because the valve in the oil supply pipeline is blocked by dirt or the valve has a throttling problem. The nozzle is too small, which is also one of the reasons for the noise. It is necessary to check and clean the valve or replace the appropriate component.
The selection of hydraulic oil for the kneading machine also needs to be carefully selected. The hydraulic oil will be difficult due to the low oil level or low oil temperature and pressure and high viscosity of the hydraulic oil. The hydraulic oil is also corroding the internal components all the time, causing damage to the internal components.
