Municipal administration intake pressure signal sends PLC control system in real time, compares the value of setting and the value of detection into control system is crossed
It is right.When intake pressure is too small, PLC control system closes third motor-driven valve, opens the first motor-driven valve and the second motor-driven valve, is avoided that
The straight pumping to city planting ductwork.Liquid level signal continual can be also transferred to by the liquid level sensor in water supply process in water tank
PLC control system, when liquid level is lower than setting value, PLC control system can control water pump and stop working to prevent water pump anhydrous
Empty pump protects the safety of water pump.
4, in water use peak phase or lower municipal water supply pressure, the first motor-driven valve and the second motor-driven valve are opened, closes the
Three motor-driven valves, municipal administration water inlet flows through intake after water tank storage and is pressurizeed after main pipe by water pump after, flow through main water outlet pipe arrival user
Use tap.Being influenced and being impacted with water pressure on city planting ductwork can effectively be reduced, prevent the case where directly taking out to city planting ductwork.
5, when low ebb is with water period or small flow water condition, the second motor-driven valve is closed, and third motor-driven valve is opened, municipal administration
Water inlet enters steady-flow tank and flows through into water main pipe, reaches user by main water outlet pipe after being pressurizeed by water pump.And it can be in water supply process reality
The intelligent water storage of existing water tank.Can be opened simultaneously to avoid the first motor-driven valve and third motor-driven valve using steady-flow tank leads to water supply flow
Deficiency causes the impact to city planting ductwork.Double loop waterbox design effective solution common single water inlet side on the market at present
The deficiency of formula provides solution of intaking under two kinds of different operating conditions for client, while guaranteeing that user uninterruptedly reliably uses water
Also the stabilization of city planting ductwork is safeguarded.Water tank water storage mainly for those hydraulic pressure instability of flow place, solve pot type supply water into
Water is unable to satisfy the requirement with water.

Internal water enters the inside of steady-flow tank 12 from the first runner pipe 18, and enters from the inside of steady-flow tank 12 into water main pipe 7
Inside is transported to the inside of main water outlet pipe 10 by water pump 16, is finally transported to from connecting tube 3 in waterpipe.Municipal administration into
When water pressure is larger, can directly it be supplied water by steady-flow tank 12, so that the available storage of water inside water tank 1.
The 1 fluid value B1 of water tank that liquid level sensor 15 will test is transmitted to control system, and control system carries out B1 and E pair
Than as B1<E, the first motor-driven valve 2 is opened, and the water flow inside the first runner pipe 18 is to water tank 1, until B1>=E, first is electronic
Valve 2 is closed.
The pressure of supply water value that discharge pressure sensor 8 detects main water outlet pipe 10 is D1, and D1 is transmitted to control system,
Control system compares D1 and D.
When D1 < D, the running frequency that control system controls whole water pumps 16 increases, and water pump 16 runs delay time and is set as t.
When the running frequency of water pump 16 is greater than 48Hz, runing time is more than t, when D1 < D, then control system sending alarm signal, and stop
The operation of equipment stops supplying water.So that equipment can obtain safe protection in use.
As D1 >=D, control system reduces the quantity that water pump 16 is run, and reduces the running frequency of water pump 16, until fortune
Line frequency is lower than suspend mode triggering frequency and reaches the suspend mode Time delay time, and control system opens sleep mode, and pressure of supply water increases
