Box pump integrated equipment principle

The water inlet pipe of the box pump integrated equipment is directly connected to the water pipe network. The water is driven into the water inlet pipe of the equipment under the residual pressure of the water pipe network. The pressure pump of the equipment continues to pressurize on the basis of the remaining pressure of the influent water to increase the pressure of the water supply. After the pressure required by the user, water is supplied to the outlet pipe network. When the user's water consumption is greater than the water supply pipe network, the inlet pipe network pressure drops, and when the device inlet pressure is reduced to a pressure less than 0 (or the set pipe network protection In the case of pressure), the device for preventing and controlling the negative pressure in the equipment will automatically start work, and the operating status of the equipment will be adjusted until the equipment is shut down to ensure that the pressure of the inlet pipe network will not be reduced any more, which will cause adverse effects on the water pipe network; when the water pipe network When the water supply capacity recovers and the pressure of the water inlet pipe network recovers above the protection pressure, the equipment starts automatically and normal water supply is restored. When the remaining pressure of the water pipe network meets the user's water supply requirements, the equipment automatically enters a dormant state, and the water pipe network directly supplies water to the user. When the water supply is insufficient, the equipment will automatically resume operation; when the user does not use water or the water consumption is small, the equipment is automatically When entering the shutdown and hibernation state, the small-flow capacity pressure-maintaining pressure tank provided on the water outlet side of the equipment will maintain the number of users and the water leakage from the pipe network. When the user uses the water pressure regulator pressure-maintaining tank to maintain the required pressure of the water supply pipe network, the equipment will automatically wake up and recover. normal operation. During the operation of the equipment, the remaining pressure of the water pipe network is fully utilized, and the water pipe network is not only adversely affected but also satisfies the user's needs to a great extent, reducing the energy consumption of the water supply and achieving excellent operation of the water supply system.
