Description
Technical field
The present invention relates to water supply project technical field, and in particular to suitable for the water supply side of supply of electric power unstable region
Method.
Background technology
Water pump is the machinery for conveying liquid or being pressurized liquid.It transmits the mechanical energy of prime mover or other external energies
Liquid, increase liquid energy, being mainly used to conveying liquid includes water, oil, acid ＆ alkali liquid, emulsion, suspended emulsion and liquid gold
Category etc..Also liquid, admixture of gas and the liquid containing suspended solids can be conveyed.The technical parameter of pump performance have flow,
Suction, lift, shaft power, water-horse power, efficiency etc.；The types such as volume water pump, vane pump can be divided into according to different operation principles.
Displacement pump is to transmit energy using the change of its swept volume of a single chamber；Vane pump be using the interaction of rotary vane and water come
Energy is transmitted, there are the types such as centrifugal pump, axial-flow pump and mixed-flow pump.
Residential houses is supplied water and mainly supplied water using centrifugal pump at present, but when restarting after centrifugal pump powers off, due to
It is in confused situation in pipeline, the resistance of ducting can not be differentiated, it is easy to cause the output of pump machine too high, cause pump machine to overload so that
Pump machine is damaged.
The content of the invention
The technical problems to be solved by the invention are when restarting after existing centrifugal pump powers off, due to the situation in pipeline not
It is bright, the resistance of ducting can not be differentiated, it is easy to cause the output of pump machine too high, cause pump machine to overload so that pump machine is damaged, and purpose exists
In providing the method for supplying water suitable for supply of electric power unstable region, solve the above problems.
The present invention is achieved through the following technical solutions：
Suitable for the method for supplying water of supply of electric power unstable region, comprise the following steps：S1：In the water inlet inwall of pump machine
Liquid level sensor is set；The draining valve being in communication with the outside is set in the water inlet of pump machine；In the delivery port of pump machine, cut-off is set
Valve；S2：When turn-off reset, opening stop valve scheduled duration；S3：If liquid level sensor detects that there is liquid water inlet,
Draining valve and stop valve then are opened simultaneously, until liquid level sensor can't detect liquid；S4：When liquid level sensor can't detect liquid
During body, draining valve and stop valve are closed, and open pump machine；S5：When the time for opening pump machine reaching threshold value, opening stop valve.
In the prior art, residential houses is supplied water and mainly supplied water using centrifugal pump, but is restarted after centrifugal pump power-off
When, due in confused situation in pipeline, the resistance of ducting can not be differentiated, it is easy to cause the output of pump machine too high, cause pump machine to surpass
Carry so that pump machine is damaged.During present invention application, when turn-off reset, opening stop valve scheduled duration so that pump machine exit
Liquid is discharged, and is prevented when pump machine starts, liquid flow-reversing impingement wheel blade, increase pump machine output, if liquid level sensor detects
There is liquid water inlet, then opens draining valve and stop valve simultaneously, until liquid level sensor can't detect liquid so that liquid from
Excluded completely inside pump machine, avoid pump machine band lotus and start, burn out pump machine, when liquid level sensor can't detect liquid, close
Draining valve and stop valve, and open pump machine, because stop valve and draining valve are turned off, pump machine start to up to working condition it
Before, liquid will not largely enter pump machine, so as to reduce the output of pump machine, avoid pump machine and be burned, when the time for opening pump machine
When reaching threshold value, that is, think that pump machine enters working condition, at this moment opening stop valve so that whole device starts into working condition
Supply water.The present invention is by setting above-mentioned steps so that when pump machine has a power failure and restarted, it may be determined that the situation in pump machine, avoid
The output of pump machine is too high so that pump machine will not overload damage.
Further, step S1 also includes following sub-step：Set in pump machine and shut down locking mechanism；When having a power failure, stop
Machine locking mechanism is locked to the pump impeller of pump machine.
Further, step S1 also includes following sub-step：The running status of pump machine is recorded, the running status includes pump
Machine current operating power and rotating speed；Each time cycle of recording process updates once.
Further, step S5 also includes following sub-step：After opening stop valve, the running status of pump machine is controlled
The running status of the pump machine recorded for the last time before power failure.
During present invention application, the operation shape for the pump machine that the running status control of pump machine is recorded for the last time before power failure
State, parameter setting is re-started to pump machine so as to avoid operating personnel, reduces human cost.
Further, the time cycle uses 1~3 second.
The present invention compared with prior art, has the following advantages and advantages：
The present invention is applied to the method for supplying water of supply of electric power unstable region, by setting above-mentioned steps so that in pump machine
Power failure is when restarting, it may be determined that the situation in pump machine, the output for avoiding pump machine are too high so that pump machine will not overload damage.
Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, with reference to embodiment, the present invention is made
Further to describe in detail, exemplary embodiment of the invention and its explanation are only used for explaining the present invention, are not intended as to this
The restriction of invention.
Embodiment
The present invention is applied to the method for supplying water of supply of electric power unstable region, comprises the following steps：S1：In the water inlet of pump machine
Intraoral wall sets liquid level sensor；The draining valve being in communication with the outside is set in the water inlet of pump machine；Set in the delivery port of pump machine
Put stop valve；S2：When turn-off reset, opening stop valve scheduled duration；S3：If liquid level sensor detects that water inlet has
Liquid, then draining valve and stop valve are opened simultaneously, until liquid level sensor can't detect liquid；S4：When liquid level sensor detects
During less than liquid, draining valve and stop valve are closed, and open pump machine；S5：When the time for opening pump machine reaching threshold value, open and cut
