The actual supply water pressure changes in real time along with the increase and decrease of a user, the supercharger is used for continuously operating, the operating speed is adjusted, the supply water pressure and the introduced water pressure are kept balanced, the servo motor 10 drives the rotary disc 7 to rotate, all the blades 8 extend out of the rotary disc 7 under the action of the thrust spring, the blades 8 push the water in the flow stabilizing tank 5 to flow into the water outlet pipe 2 at an accelerated speed, the water is pressurized and supplied, and when the water is normally supplied, the water flow impacts the flow direction plate 14, so that the flow direction plate 14 deflects towards the flowing direction of the water; when the water supply volume reduces and leads to supplying with water pressure increase, the water of outlet pipe 2 department begins the refluence, prevent that the subassembly that flows backwards closes, water stops flowing, flow direction board 14 resets under the effect of coil spring, contact switch 15 contacts control circuit, control circuit makes electro-magnet 9 circular telegram, electro-magnet 9 produces electromagnetic suction attracts all blades 8 to retract into carousel 7, even if servo motor 10 does not shut down, a plurality of blade 8 also no longer carries out the pressure boost to water and supplies, the rotation inertia that can not receive servo motor 10 stall back carousel 7 influences equally, carousel 7 and a plurality of blade 8 do not receive the influence of water flow inertia and water-catching, play the guard action to a plurality of blade 8, prevent servo motor 10's torque increase and lead to the coil to burn out.
When the water pressure on one side of the supercharger rises and is higher than the supplied water pressure, the slide core 23 drives the valve core of the unloading three-way valve 26 to move, the unloading three-way valve 26 plugs the middle position of the water outlet pipe 2, the water pressure pushes the driving slide plug 171 open and then continues to push the driven slide plug 172 open, the water flows through the backflow preventing component, when the supplied water pressure increases due to the decrease of the supplied water quantity, under the action of the pressure, the reset spring 18 pulls the driven slide plug 172 to plug the second check ring 20 again, the slide core 23 drives the valve core of the unloading three-way valve 26 to switch the position, the unloading three-way valve 26 opens the middle position of the water outlet pipe 2, and the backflow-preventing impurities in the water are clamped between the driven slide plug 172 and the second check ring 20, the tightness of the second check ring 20 is damaged, backflow water can flow out from the middle position of the water outlet pipe 2, the sliding core 23 is switched to the position, meanwhile, the blocking pin on the sliding core 23 hooks the steel cable 21 to drive the steel cable 21 to tighten, the steel cable 21 pulls the active sliding plug 171 to seal the first check ring 19 until the supplied water pressure is lower than the water pressure after the booster is boosted, the sliding core 23 moves to release the compression on the steel cable 21, the active sliding plug 171 can be opened again, the backflow prevention assembly is arranged to prevent the supplied water from flowing back to the steady flow tank 5 to generate on-way flowing pollution, and the supplied water pressure is timely unloaded to prevent the pipeline from being damaged.
The far control pipe 28 controls the valve core of the pressure maintaining three-way valve 27 to move by utilizing the water pressure in the external network pipe and the water pressure supply level, the servo motor 10 drives the air pump 12 to work through the rotating shaft 11, in the normal water supply working process, when the water pressure at the supply end is low, the gas discharged from the air pump 12 is guided into the steady flow tank 5 through the pressure maintaining three-way valve 27, the water pressure at the supply end is increased, if the water pressure at the supply end is increased, the pressure maintaining three-way valve 27 discharges the gas in the steady flow tank 5, the water level in the steady flow tank 5 is raised, preparation is made for increasing the flow and pressurizing of the water supply end, and the supplied water pressure and water flow are ensured to be stable through the arrangement of the pressure stabilizing component.
