The device can complete the monitoring of rainfall and abandonment flow, and monitor the rainfall frequency to truly collect the ideal rainwater.


Initial rainwater filtration device
The product uses the gravity flow of rainwater to automatically separate the garbage and water from the rainwater, resulting in cleaner rain. The rain changes the flow direction through the elbow inside the device, flows in the vertical direction, encounters the umbrella-shaped diversion structure, so that the rain flows along the umbrella edge, contacts the vertically placed filter net, and the rainwater filters through the filter and flows to the clean water chamber. The mesh surface falls to the garbage receiving port, so that the rainwater is filtered, and the garbage is diverted and automatically discharged. The automatic rain filter has high filtration precision and the mesh diameter reaches 0.4mm. It is generally installed after the sewage interception and abandonment filtration. The filtered rainwater can be directly greened and poured, which is very effective. The drain pipe of the filter can be directly made into an infiltration property without directly docking with the drain pipe.

2. Pressure setting: The water pressure of the municipal water pipe network can be set by adjusting the permissible pressure control valve.
3. By pressure (or stacking): When the pressure and flow rate of the water is allowed to exceed the pressure, it can be pressurized on the basis of the pressure of the water pipe network. It can reduce the number of pumps or (and) reduce the speed to save energy when running compared to water from ordinary reservoirs.
4. Variable frequency constant voltage: The equipment detects the outlet pressure through the sensor in real time, compares the detected value with the set value, determines the number of sets of motors and pumps, and the output frequency of the inverter (reacts to the motor and the pump for the speed) to chase the water. The curve achieves constant pressure.
5, no noise: Adopt modern design concept, fully consider the modern people's requirements for the environment, select the silent special frequency converter, use the sound-absorbing design means, so the system can operate ultra-quiet.
