Why Is There a Need for Cooling Water When KOS Emulsifying Pump Is Working

The emulsifying pump is a device that is used for stirring, homogenizing, crushing, emulsifying, mixing and dissolving fluid materials. It features stable performance, low noise, convenience as well as high production efficiency. The emulsion pump can be used alone or connected to the pipeline. When the pump is working, the material is turbulent under the action of the stirring impeller. Then the material is thrown into the high shear area. In the rotation of the rotor, the pressure of the material in the impeller region changes constantly which generates high frequency pressure wave. In the meantime, the high-speed rotation of the rotor and the edge of the multilayer rotor slot also produce great shear force to the material. Besides, the material goes under the inertial centrifugal force and impact force. Finally, it is mixed and dispersed in the turbulence from the vessel. Therefore, the emulsifier pump produces shear, impact, friction, tear, emulsification effect to the material relying on the operation between the stator and the rotor. While operating the machine, we need to pay special attention to cooling water connection.

In the body of an inline homogenizer, there is an inlet and outlet for cooling water. With cooling water, the mechanical seal of the pump can be well protected. Before use, the cooling water for mechanical seal should be well connected. It is all right to use the tap water. The machine cannot be started to run until the material enters its working chamber. What’s more, the emulsifier pump is supposed to run with materials in it, so we need to be careful and should not race the pump. If it does idle while working, the mechanical seal will be burned by high temperature which consequently influences the service life of the pump badly. After use, the high shear emulsifier should be switched off before cutting off the cooling water.

From the above, we know that the access to cooling water is to protect the service life of the mechanical seal of the pump. Apart from that, we should also pay attention to motor rotation over and over again because the motor should run in the same direction as the main shaft to work properly. Thus, it is strictly forbidden that the motor runs oppositely. Moreover, after use, the working chamber, stator and rotor should be cleaned thoroughly. All of these methods do well in increasing the life span of the emulsifying pump.
