Second, the home improvement circulating water system-how to install the water circulation system?
1, the inlet pipe must be sealed and reliable, and must have a bracket, and shall not be hung on the water pump. When installing a water inlet pipe with a bottom valve, the axis of the bottom valve should be perpendicular to the horizontal plane as much as possible, and the included angle between the axis and the horizontal plane should not be less than 45 degrees. When the water source is a channel, the lower valve must be more than 0.5 meters at the bottom, and the pipe network must be prevented from entering the pump.
2. The base of circulating water plus heat pump must be horizontal, and the connection with the base must be firm. When the machine and pump belt are driven, the tension side of the belt is facing down. In this way, the pump impeller must rotate in the direction indicated by the arrow. When using coupling transmission, the machine and the pump must be coaxial.
3. The installation position of circulating water plus heat pump must meet the requirements of allowable suction height. The base must be horizontal and stable to ensure that the rotation direction of the motor is consistent with that of the water pump.
4. If there are multiple devices in the same computer room, the distance between devices, between devices and between devices and walls should be greater than 800 mm ..
5. The suction pipe of circulating water plus heat pump must be sealed, and elbows and gate valves must be as few as possible. When adding water, air must be pumped out, and there must be no air accumulation during operation. The nozzle must have a certain immersion depth.
3. How to use the hot water circulation system?
The circulating pump of the water heater is an electrical device, which can make the hot water arrive quickly. It has no heating function, but it will make the water cooled in the hot water pipe flow back to the water heater for secondary heating. It takes the hot water circulating pump as the power and adopts the way of continuous hot water circulation to transfer heat (or hot water) from the "collection end" to the "use end" to save water and improve water use efficiency. The convenience of using domestic hot water.
The above is Xiaobian's knowledge about the circulating water system in home decoration. After understanding, everyone hopes that the installation and purchase can go smoothly, specifically.
