A solar panel can install two pumps at the same time, a water pump and an outlet booster pump.
1. We all know that the installation of ordinary household solar water heaters requires a height difference. Only with a height difference can the outlet water have pressure. Otherwise, the outlet water pressure may be too low. used normally.
Notice: Minimize the layout of the pipes during installation. It is best for solar water heaters and water points to be perpendicular to the horizontal line, and avoid advection pipes and elbows. One more elbow is equivalent to reducing the water pressure by 1/4. The same goes for advection pipes. The water pressure in the pipe itself is low. The water in the advection pipes depends on the force of the water in the vertical pipes to flow.
Second, use as much as possiblelarger diameter pipes. When the height cannot be changed, increase the flow rate of the water supply to increase the water flow.
Again, if the above methods have been used, but the water pressure problem still cannot be completely resolved, we will install a water outlet booster pump . Here we recommend not using the water pump so much. possible, because the water pump The maintenance rate is still quite high. If it is to be used, heat dissipation should be carried out in summer to ventilate the working space, and the water pump pipes should be well insulated in winter to prevent freezing and cracking.
Second, first analyze the most likely possibility, that is, the tap water pressure itself is insufficient. If the tap water pressure itself is insufficient, we have no other selection conditions and chooseIt is wise to install a water booster. pump to increase tap water pressure. Note that the start and stop of the water pump must be synchronized with the water supply solenoid valve. And take protective measures for the water pump. Dissipates heat in summer and retains heat in winter.
Let's first see how the solar water heater pipes are connected. 1. The water addition valve and the heat valve are two independent valves, but they are one pipe (at the bottom of the water heater) leading to the solar water heater. So, after filling the water, you need to close the water fill valve. 2. Generally, the pipe that overflows when water is full is at the top of the water heater, and water will flow out when it is full. It looks like your valve is probably the main valve connected in series in front of the water supply valve. You should know its uses without reading the descriptionprevious section.
