Specific embodiment
With reference to accompanying drawing to further explaination of the invention, its operation principle and the actual technical problem for solving are explained.
As depicted in figs. 1 and 2：A kind of standby pressurization cycle pump of fire fighting supply, it is characterised in that it include tank 1 and
The feedwater piping 2 of tank connection, including at least one set of adjusting part 3 for being connected by feedwater piping 2 with tank 1 and with
Control cabinet 4 of the adjusting part 3 by being electrically connected with and for controlling its signal output；It is provided with described tank 1 single
Discharging device, fire demand water is connected with the outlet pipe 6 in the discharging device, is additionally provided with for monitoring water outlet on outlet pipe 6
The flowmeter 5 of flow；Described adjusting part 3 includes being arranged on fire pump 31, first electro connecting pressure gauge 32 of main pipeline, with
And it is connected in parallel on circulating pump 34, the second electro connecting pressure gauge 35, regulating valve 7 and filter 33 on supervisor；The first described electricity
The fire pump 31, circulating pump 34 that contact pressure table 32, the second electro connecting pressure gauge 35 are separately mounted in the adjusting part 3 goes out
After water, before regulating valve 7.
Preferably, described flowmeter 5 is electrically connected with control cabinet 4, with to control cabinet 4 send water flow reach it is default
The electric frequency signal of value.
Preferably, it is separately mounted on first electro connecting pressure gauge 32, the second electro connecting pressure gauge 35, and positioned at giving
Place is provided with pressure sensor in waterpipe 2.
Preferably, it is equipped with relay on the first described electro connecting pressure gauge 32, the second electro connecting pressure gauge 35.
Preferably, described control cabinet 4 is made up of Fire Fighting Pump Control cabinet 42 and circulating pump switch board 42, its Fire Fighting Pump Control
Cabinet 42 interrupts opening for the fire pump 31 when the arrival preset value of the first electro connecting pressure gauge 32 relay connection is received
Open；When circulating pump switch board 42 receives second electro connecting pressure gauge 35 and reaches preset value relay and connect, interrupt described
The unlatching of circulating pump 34.
Preferably, described tank 1 is open tank.
With reference to Fig. 1-Fig. 2, the operation principle to patent of the present invention is described：
Four pressure monitor points are provided with the controls, and pressure sensing is provided with the electro connecting pressure gauge at big pump and small pump
Device, starts fire pump 31 at first during beginning, internal pipe pressure begins to ramp up, and when internal pressure reaches P4, relay is connect
Logical, Fire Fighting Pump Control cabinet 41 sends signal, and fire pump 31 is closed, if now carrying out fire demand water, causes internal pipe pressure
Value can up and down fluctuate in P4；After fire pump 31 is closed, control end circulation does not terminate also, if the flowmeter of monitoring water flow
5 change, and circulating pump 34 can then start, and now internal pipe pressure this critical value can up and down be repeated several times fluctuation in P4,
The frequent starting of fire pump 31 of relatively high power can be at this time prevented, the effect for reducing power consumption is reached, until pipeline inside is pressed
Power reaches critical value and fire demand water stops water delivery, then terminate the circulation of whole control end, and circulating pump 34 is closed.
In view of fire cistern is for a long time in the full state of water, fire pump is in dormancy, when observer checks water level in water pool,
Starting fire pump 31 when relatively low carries out moisturizing, untill pond fills water.
