In order to improve the timeliness of a water supply system and the stability of a heat pump central air-conditioning system, as shown in fig. 1, an embodiment of the present application provides a water pump circulation control method, including:
s101, acquiring a starting sequence of a water pump unit;
s102, starting a first priority water pump according to the sequence of the starting sequence;
s103, recording the starting time length of the currently started water pump and the first connection break opening time length of an overload switch of the currently started water pump;
and S104, when the opening duration is greater than a first duration threshold value and the opening duration of the first connection break reaches a second duration threshold value, switching to a second priority water pump according to the starting sequence, and replacing the sequence of the first priority water pump and the second priority water pump in the starting sequence.
Through obtaining the start sequence, can come automatic opening water pump according to the order of start sequence, preferentially start first priority water pump, can reduce the maintenance personal and switch the manual operation who starts the water pump to improve the switching efficiency of water pump, also guaranteed the promptness of supplying water, also reduced central air conditioning system's shutdown operation simultaneously, and then improved heat pump central air conditioning system's stability. After the water pump is started, the starting time of the water pump and the first disconnection time of the overload switch of the water pump are recorded, and when the first starting time is longer than the first time, the currently started water pump can be considered to normally work. If the opening time of the first break reaches the second time, the currently opened water pump is considered to be overloaded, the water pump is switched to the second priority water pump according to the starting sequence, the overloaded first priority water pump can be closed, the second priority water pump is replaced to ensure continuous water supply, and even if the circulating water pump of the current first priority has faults, the water supply system continuously operates.
The first priority water pump with overload fault can be directly repaired. In addition, after the first priority water pump is switched to the second priority water pump, the sequence of the first priority water pump and the second priority water pump in the starting sequence is replaced, when the water pump needs to be started next time, the second priority water pump is started preferentially, and the first priority water pump is prevented from being started continuously before the first priority water pump with overload faults is maintained.
Preferably, the first time is 5 seconds, and when the first priority water pump or the second priority water pump is started for more than 5 seconds, the first priority water pump or the second priority water pump can be considered to be in a normal working state; the second time is 2 seconds, and when the break time of the overload switch of the first priority water pump or the second priority water pump exceeds 2 seconds, the overload fault of the currently opened water pump can be confirmed.
The overload fault of this embodiment can be the water pump state that multiple condition caused is unusual, and the unable rotation of water pump is blockked up by the foreign matter, or the pipeline is blockked up by the foreign matter and leads to the load grow of water pump. When the load of the water pump is increased or the water pump is locked, the current of a motor coil of the water pump is overlarge, the temperature is rapidly increased, and a thermal overload relay arranged in the water pump detects that the temperature is increased beyond the limit; or other types of protectors detect the water pump abnormity, and the overload switching signal of the water pump can be fed back to indicate the water pump state abnormity.
In one embodiment, the water pump cycle control method of the present application further comprises the steps of:
after replacing the sequence of the starting sequences of the first priority water pump and the second priority water pump, sequentially overlapping the overload switching times;
and when the overload switching times reach the first time threshold value within the appointed time, stopping switching the water pump.
That is to say, the first priority water pump and the second priority water pump are overloaded within the specified time, which indicates that the water pump system cannot solve and repair the overload fault by switching the water pumps, and the operation of switching the water pumps is not needed any more.
For the preferred embodiment of the first time threshold, the first time threshold ranges from 2 to 6 times, that is, the first priority water pump and the second priority water pump each continuously overload at least 1 time, and it can be considered that the first priority water pump and the second priority water pump both have overload faults. More preferably, the first time threshold is 4 times, that is, the first priority water pump and the second priority water pump are overloaded for at least 2 times continuously, so as to avoid misjudgment.
Further, before a starting sequence of the water pump unit is obtained, the water pump unit is started;
and judging fault removal information of the water pump unit during the last operation, determining that the water pump unit is started after fault removal, and if not, not starting, so that pipeline damage and heat pump unit damage caused by forced starting of a faulty water pump are avoided.
Furthermore, the step of judging the troubleshooting information of the water pump unit during the last operation comprises the following steps:
judging the overload condition of the water pump, and if the water pump is overloaded, further judging whether the overload fault of the water pump is recovered;
when the overload fault of the water pump is recovered, the water pump can be continuously started.
And judging the water flow protection condition, if the water flow protection exists, further judging whether the water flow switch is closed, and if the water flow switch is closed, continuously starting the water pump.
In addition, before starting the water pump unit, the on-off demand information of the water pump is obtained; and when the water pump is determined to be required to be started, the operation of starting the water pump is executed again.
Judging whether the water pump overload fault is recovered or not, wherein the operation comprises the steps of acquiring overload protection information of the water pump when the water pump starting and stopping demand information indicates starting; whether to continue to check the manual recovery operation can be decided according to the condition indicated by the water pump overload protection information.
Acquiring manual recovery operation information when the water pump overload protection information indicates existence; obtaining manual restore operation information may determine whether manual intervention has been performed to remove the fault or change the operating state of the water pump.
When the manual recovery operation information indicates existence, acquiring water flow protection information; if a manual recovery operation is performed, that is, the overload fault is eliminated, it is also necessary to eliminate whether the water flow fault exists. The water flow failure means that water in the pipe is not flowing sufficiently, water leakage may occur, and the water in the pipe may evaporate less as the use time elapses.
Judging whether the water flow switch is closed or not, wherein the water flow switch information is acquired when the water flow protection information indicates existence; that is, when it is confirmed that there is no water flow fault, it is determined whether there is water leakage according to the water flow switch information.
When the water flow switch information indicates to be closed, water leakage can be eliminated, the starting sequence is obtained at the moment, and the operation of starting the specified water pump can be continuously executed.
More preferably, the water pump circulation control method of the present application further includes:
and after the switching of the water pump is stopped, changing the overload protection information of the water pump into a fault state, and sending the overload protection information of the water pump.
After receiving the water pump overload protection information, a maintenance person or an on-duty person can quickly know that the first priority water pump and the second priority water pump have overload faults, and needs to stop the operation of the water pump system and maintain the water pump system, so that the maintenance efficiency is improved.
Preferably, when the water pump overload protection information indicates that the water pump overload protection information does not exist, that is, the system does not have an overload fault, it may be determined that no manual intervention operation has been performed, it may be directly determined whether the water flow protection information exists, and it may be further determined whether the water flow fault exists;
in addition, when the water pump overload protection exists and the manual recovery operation information indication does not exist, or when the water flow switch information indication is turned on, it is indicated that the overload fault is not eliminated and recovered, the water flow switch is not closed, the water pump unit cannot be started at the moment, and the water pump start-stop requirement information indication needs to be continuously judged to be started or closed;
moreover, when the water flow protection information indicates that the water flow protection information does not exist, no water flow fault exists, the starting sequence can be directly acquired, and then the water pump with high priority is started.
Still preferably, after stopping switching the water pump, namely confirming that the overload fault occurs, obtain the ambient temperature value, when the ambient temperature value is greater than the temperature threshold, can think that the pipeline does not have the risk of icing, change water pump on-off demand information this moment and close for the instruction, can in time close all water pump units after the overload fault occurs.
The temperature threshold value can be 3-8 degrees, the preferred value can be 3 degrees, if the water temperature is lower than 0 degrees, the pipeline is easy to freeze, at the moment, the water pump needs to be kept to act to prevent the pipeline from freezing to damage the heat pump central air-conditioning system, and the heat pump central air-conditioning system cannot be damaged even if the water pump is overloaded and damaged. If the temperature is 3 ℃ as the limit, the machine can be directly stopped to remove the overload fault of the water pump, and the pipeline cannot be frozen when the water pump is stopped.
Further, when the ambient temperature is less than or equal to the temperature threshold, the first priority water pump and the second priority water pump are started simultaneously, all the water pumps are started to drive the water of the pipeline to flow, the pipeline is prevented from being frozen, the whole water pump unit is damaged, and at the moment, if the water pumps are overloaded or have faults, the damaged water pumps are only the water pumps.
In addition, the water pump circulation control method of the present application further includes:
when the on-time of the first continuous break switch is smaller than a second time threshold, acquiring a second continuous off-time of the water flow switch; and preliminarily judging whether the water flow fault exists according to the second continuous off time length of the water flow switch.
When the starting time length is greater than a third time length threshold value and the second continuous disconnection time length reaches a fourth time length threshold value, the water flow fault is possibly existing, and at the moment, the water flow protection switching times are obtained to further judge whether the water flow fault really exists or not;
when the water flow protection switching frequency reaches the second time threshold value, the existence of water flow faults can be confirmed, the water flow protection information is changed to be in a fault state, the water flow protection operation is started, the water pump opening and closing requirement information is changed to be in indication closing, and the water pump is stopped to be started to supply water.
Preferably, when the water flow protection switching frequency is smaller than the second frequency threshold, the currently started water pump is switched to replace the starting sequence of the first priority water pump and the second priority water pump. Specifically, the on-off states of the first priority water pump and the second priority water pump can be obtained, and the on-off states of all the current water pumps can be checked;
if the first priority water pump is started and the second priority water pump is stopped at present, it may be that the operation of the first priority water pump has a problem, resulting in a water flow fault in the pipeline, and therefore the first priority water pump is stopped and the second priority water pump is started, and water is supplied by the second priority water pump. And replacing the starting sequence of the first priority water pump and the second priority water pump, and then overlapping the water flow protection switching times to show that the water pumps are switched.
If the second priority water pump is started and the first priority water pump is closed at present, the problem possibly occurs in the operation of the second priority water pump, at the moment, the second priority water pump is closed, the first priority water pump is started, and the first priority water pump is switched to continue water supply to the system. At this time, the starting sequence of the first priority water pump and the second priority water pump is replaced, the first priority water pump is started firstly when the water pump is started next time, then the water flow protection switching times are superposed, and the fact that the water pumps are switched is also shown.
Optionally, the water pump circulation control method of the present application further includes:
when the water flow protection switching times do not reach the second time threshold value and the opening time reaches the fifth time threshold value, even if the currently opened water pump does not have overload faults or water flow faults, strain can occur when the currently opened water pump is opened for a long time, the currently started water pump is switched at the moment, the starting sequence of the first priority water pump and the second priority water pump is replaced, and the water flow protection switching times are sequentially superposed
Acquiring the opening and closing states of a first priority water pump and a second priority water pump, and checking the opening and closing states of all the current water pumps;
if the first priority water pump is started and the second priority water pump is stopped at present, the first priority water pump is closed, the second priority water pump is switched to be started, the second priority water pump is used for continuously supplying water, the starting sequence of the first priority water pump and the second priority water pump is replaced, and the second priority water pump is started preferentially when the water pump is started next time;
and if the second priority water pump is started and the first priority water pump is stopped at present, the second priority water pump is closed, the first priority water pump is switched to be started, the starting sequence of the first priority water pump and the second priority water pump is replaced, and the first priority water pump is started preferentially when the water pumps are started next time.
So, can reduce first priority water pump and second priority water pump and take place the strain because of long-term work, can increase of service life.
Particularly, when the water pump opening and closing requirement information indicates that the water pump is closed, the first priority water pump and the second priority water pump are directly and simultaneously closed, and all the water pumps can be maintained or replaced. When the heat pump central air-conditioning system needs to be started, the water pump starting and stopping demand information is changed into indication starting, if manual recovery operation occurs, the first priority water pump or the second priority water pump is indicated to be manually maintained, the water pump overload protection information and the water flow protection information can be changed into non-existent, the overload switching times or the water flow protection switching times are reset, and subsequent fault misjudgment is reduced.
