Water Pumps In Heating Industry
A circulating water pump is a hub connecting a heat source, a heating network, and an indoor heating system. In general, they are more efficient than those that pump heated air because almost every home has a nearby water source, and therefore does not require electricity to heat air, but rather relies on the temperature of the water being pumped in. Benefits include lower cost, reduced energy requirements, and the ability to function in high humidity settings. Though multiple options are available, selecting and installing the correct model are exceptionally important, as they provide warmth to millions of households.
Several factors can affect heating capabilities, and a lack of knowledge of proper installation, use, and function of the water pumps involved can result in irreparable damage. For example, the valve at the outlet of the circulating water pump cannot be opened 100%. The rated current must be allowed to control the opening of the valve; otherwise, it will cause the actual running of the motor. If the current exceeds its allowable rate, the motor will burn out.
The following features should be specifically considered when selecting a circulating water pump:
- The end suction pump should meet the maximum flow and head required in the system
- The optimal working point of the pump should be as close to the actual operating point of the system as possible
- Long-term operation in the high-efficiency zone should be planned to maximize cost-effectiveness
- The selection of a water pump with a simple structure, small size, lightweight, and relatively high efficiency should be made.
- The end suction pump should be safe, reliable, stable, have low vibration, low noise, and good anti-cavitation performance during operation.
- It is suitable for heavy duty water pumps with large flow and small head changes, that is, water pumps with a flat performance curve.
