Pump hot water with the installation of
Living in the attic of the user, because users of solar water tank with tap water level difference is very small, not enough water pressure, water quality, and can not meet user requirements, in this case, it is necessary to use hot water pump to provide hot water. The method is suitable for small water pressure, need to boost the situation.
Living in the attic of the user, because users of solar water tank with tap water level difference is very small, not enough water pressure, water quality, and can not meet user requirements, in this case, it is necessary to use hot water pump to provide hot water. The method is suitable for small water pressure, need to boost the situation.
When the lower solar installation position or the top floor of the user, if the water level in the tank water taps than 5 meters above the outlet, the water pressure is not to 0.5 kg, the user will feel very slow water flow, which is heating the water poor quality. Change the way is to add a booster pump, so that water pressure can be up to 2 kg, significantly improved the quality of water.
Many different types of booster pump, but at higher temperatures, performance, high quality requirements. Relatively good results Ville Germany, Denmark, Grundfos, South Korea, Hanjin, etc., such as Shanghai China Xishan, Guangzhou and other lower quality format too, but can also be used. Hot water supply pump is automatic, once the user opens hot water tap, water pump is automatically turned on, pressurized water supply. These two types of pumps, water flow and pressure on open, its principles will be described in later chapters. Shown in Figure 4-3-6.
Figure 4-3-6 with hot water pump schematic (flow switch)
Principles of explanation: When the user opens the hot water tap, the down the pipe in the shed, start the water flow switch 5, the flow switch connected to the pump power, pump water to the front of the user Department. The most commonly used pumps in two forms: swing-type water flow switch and pressure switch, the specific principles in detail in later chapters. Using pressure-type solar water pump can be placed in the program lower than the position of the tap water, such as the grass in the upper villa.
