The water supply can be supplied at the same time, but the outlet pipe of the water pump must be equipped with a one-way check valve to prevent tap water from flowing through the pump when it is not on. A two-way check valve should also be installed at the water outlet from the tap and water meter (this will prevent the tap water from being cut off. When using a water pump to pump water water, water will not flow through the water line) Two of the check valves are required.
I can only think of one way to 'use the siphon. Of course, the principle of this method is that the water is pumped out. The land must be geographically higher than the ground. land from which water is delivered. There is also the principle of water hammer, which is as follows:
A water hammer pump is an advanced water pump that uses flowing water as energy, produces an ewater hammer effect by mechanical action and converts low water levels. head energy in a high water head energy device.
The water hammer pump mainly consists of six parts: inlet pipe, pump body, drain valve, center valve, pressure tank and outlet pipe .
Using flowing water is suddenly slowed down. A pump that uses generated energy to raise a portion of the water pressure to a certain height. The picture shows the working diagram of the ram pump. When the water flowing downward along the water inlet pipe reaches the vicinity of the one-way valve A (static head valve), the momentum of the water flow (as long as the speed of flow is large enough, there is sufficient momentum) causes the valve to close quickly. The water flow suddenly stops flowing and the kinetic energy of the water flow is convertedin pressure energy. Then the water pressure in the pipe increases and the one-way valve B is opened. inner tube and rises to a certain height along the outlet pipe. Subsequently, due to the decrease in pressure in the water inlet pipe, valve A automatically falls under the action of static weight and returns to the open state. At the same time, compressed air in the inner tube causes valve B to close and the whole process repeats. Using a water hammer pump, the water flowing through the inlet pipe can be raised by approximately 15% to a height equivalent to 5 times the height of the inlet pipe of water. The efficiency of the water hammer pump η=ε·嗞. In the formula, 嗞 is the ratio of the pressure-rising water flow rate to the downward-flowing working water flow rate; ε is the height of pressure rise plus the ratio between the height of loss in the outlet pipe and theworking waterfall. Good water hammer pump efficiency can reach 86%. The installation inclination of the water inlet pipe is between 1:9 and 1:4 to achieve the best water flow braking effect. The water hammer pump has no moving working components, has a simple structure, does not require an external power source and does not require dedicated supervision. When designing the pump, the strength of the pump components must be considered to avoid breakage due to water hammer.
