Working principle of HFYXBF series box pump integrated pump station
When the equipment is first operated, the pressure protection value is set based on the minimum inlet pressure limit of the local water supply network. The tap water flows into the inlet of the pump unit and the water tank, and the air in the water tank is automatically discharged through the ventilation port. The equipment is powered on and placed in automatic working mode. The microcomputer control system real-time detects the inlet pressure of the tap water pipeline network and the supply pressure of the user pipeline network.
When the water supply in the tap water network is sufficient and the water supply pressure fully meets the pressure requirements of the user's network, the microcomputer control system puts the water pump into sleep mode or enters stable pressure through the stabilizing system to maintain the state. The user's water is directly supplied to the user from the equipment bypass pipe, saving 100% energy
During peak water usage, when the water supply in the water supply network is sufficient but the pressure is insufficient, the microcomputer control system will start the water pump with variable frequency soft start based on the water inlet pressure of the water pump and the user's required water volume, and implement superposition boosting. The difference will be compensated according to the amount, fully utilizing the original pressure of the water supply network while ensuring a constant pressure required by the user.
When the water supply pressure of the tap water network drops to the pre-set protection pressure value, the microcomputer control system uses intelligent overlay protection devices to ensure that the water supply pressure of the tap water network no longer drops, the pressure of the bottom layer direct water supply user network is not damaged, and the pressurized user water volume can meet the requirements.
When the water supply of the tap water network is insufficient and the pressure is also insufficient, the microcomputer control system and intelligent overlay protection device coordinate their actions. The intelligent water inlet device connected to the water pump inlet pipe of the water tank automatically opens, taking water from the water tank and supplying variable frequency water to the user, ensuring that the equipment does not generate negative pressure in the tap water network and can fully guarantee the normal use of water by the user.
When the system loses power, restore natural water supply to the tap water network, and automatically wake up when power is restored.
When the water supply network stops running and the water level in the water tank drops to the lowest level, it will automatically shut down. When water comes in, it will resume normal operation.
