The quality R Hot Water Circulation Pump setting method
The setting method of quality R Hot Water Circulation Pump, the knowledge of the setting method of the hot water circulation pump comes from the experience sharing and exchange of experience of millions of professionals in the construction engineering industry on the cost notification cloud platform, the knowledge of the setting method of the hot water circulation pump, so the heat What is the setting method of the water circulation pump?
1. The flow rate is generally determined by the percentage of the designed hourly hot water volume. For the monomer, the designed hourly hot water volume is 25~30; for the residential area, the design hourly hot water volume is 30~35.
2. The quality R Hot Water Circulation Pump is controlled by the temperature sensor of the return water pipe in front of the pump to control the start and stop. The start-stop temperature is generally 10° higher than the hot water supply temperature, and the pump is stopped at 5° lower.
3. The lift of the quality R Hot Water Circulation Pump shall be calculated according to the above flow rate through the loss of the water supply and return water pipelines. If it is through an instantaneous or semi-instant heater, the loss shall also be calculated or determined according to the parameters given by the manufacturer. . The two are added together, and then magnified by a multiple of 1.1 as the head of the circulating pump.
