Abstract
The utility model discloses a closed-loop flow numerical control system based on a waterproof test. The system comprises a turbine flow meter, a PLC, a frequency converter and a water pump, wherein the water pump and the PLC are respectively connected with the frequency converter and the turbine flow meter, a filter is arranged between the water pump and the turbine flow meter, one end of the turbine flow meter is connected with a water supply pipeline, and the water pump is connected with a water tank. A raindrop box is of a sealed structure, the top of the raindrop box is provided with an exhaust valve, the exhaust valve is closed after the box is full of water to form a vacuum state, namely the water inlet flow equals the water outlet flow, and the rainfall is accurately controlled. According to the flow value, the enclosed-loop system composed of the turbine flow meter, the PLC, the frequency converter and the water pump can control and adjust the water pump in real time via the frequency converter, so that the flow can be stabilized into a set state, and is not interfered by external factors.
