Methods for Dealing with Liquid Solidification in Slurry Pumps at Low Temperatures

1. Choose appropriate materials and take insulation measures

The rubber pump body of the slurry pump tends to harden at low temperatures, resulting in a decrease in pump flow and pressure. Therefore, in low-temperature environments, rubber materials with good cold resistance should be selected, or insulation measures such as adding an electric heat tracing system should be taken to maintain the temperature of the pump body.

2. Drain the residual liquid from the pump body and rinse it with antifreeze

To prevent the liquid inside the pump from solidifying, the residual liquid inside the pump can be drained and rinsed with antifreeze before the pump stops running. This can reduce the possibility of liquid solidifying inside the pump body.

3. Strengthen pipeline insulation and regular inspections

The water inside the pipeline is prone to freezing at low temperatures, leading to pipeline rupture and damage. Therefore, when using slurry pumps in winter, insulation measures for pipelines should be strengthened, such as adding insulation layers or electric heating systems. At the same time, regularly check whether there is icing in the pipeline, and if it is found, it should be dealt with promptly.

4. Regular inspection and maintenance

Regularly preheating the pump can also effectively prevent liquid solidification. In addition, regularly checking the operating status of the pump, promptly identifying and addressing potential issues, is also an effective measure to prevent liquid solidification.

5. Anti freezing measures during the shutdown process

During the shutdown process, the water inside the pump body should be blown clean or drained, and the inlet and outlet cooling water should be closed. The pump body plug should be opened to drain the stored water inside. Possible effective isolation of incoming water or steam pipelines. Regular inspections. Long term shutdown is recommended to blow out all circulating water in the device area and protect machine 3 with nitrogen.
