Cold water pumps and hot water pumps are often used in crafts, but they are not universal. What are their differences and precautions when used?

First of all, the definition of hot water pump and cold water pump: The commonly used cold water pump refers to the pump that can transport temperature liquid below 80 ° C. The pump with temperature between 80 ° C and 120 ° C is generally called Hot water pump.

The difference between cold water pump and heat pump, welcome everyone to leave a message to continue to add:

1. The selection of materials is different. The thermal pump should be used with heat resistance, and the thermal pump should be 13%CR steel. The cold water pump can not be used.

2. Pay attention to the gap between dynamic and static, some are different.

3. Consider the expansion coefficient and difference of all materials as a whole.

4. Consider installation. After heating, it must have the guidance of neutrality and heat expansion. This is the same as a large unit.

5. Consider thermal insulation and consider the temperature difference between the upper and lower four -around shell to cause deformation and cause an accident.

6. The sealing method may be different.
