。The priming tank 5 is also provided with a water level sensor 8, which includes an upper limit electrode 8a, a lower limit electrode 8b, and a common electrode 8C.
The detection signal of this water level sensor 8 is sent to the pump control panel 9.
is given, and the pump control panel 9 issues a full water alarm (upper limit alarm).
A low water warning (lower limit warning) is issued. Among these, regarding the water reduction alarm (lower limit alarm) on the pump control panel 9, when the - degree water reduction alarm is issued, the water reduction alarm will be latched and displayed, and even if the water level recovers, the pump control panel 9 will not be displayed even if the water level has recovered. The latch of the low water alarm cannot be released unless the provided recovery switch 10 is operated.

うにしている。By the way, in such fire pump equipment, in order to ensure that the pump can operate reliably in the event of a fire, operational tests are periodically conducted to check whether the fire pump 1 can provide the expected performance. Therefore, a test pipe 11 is provided which returns to the underground water tank 2 from the discharge side of the fire pump 1, and this test pipe 11 has an electric valve 12. A flow meter 13 and a manual valve 14 are provided, and a control signal from a test control device 15 is given to a pump control panel 9 to perform pump start control.
At the same time, the electric valve 12 is opened to allow the rated flow rate initially set by the manual valve 14 to flow through the test pipe 11, and in this state, the pump discharge pressure and suction pressure, as well as the voltage and current of the pump drive motor, etc. are measured to determine the desired pump condition. I am trying to check whether the performance can be obtained or not.

されるか否か点検するようにしている。In addition, during the operation test of the fire pump, it is also checked whether the water level in the priming tank 5 provided as ancillary equipment to the fire pump 1 is being detected normally. That is, while the pump is stopped, the test control device 15 opens the electric valve 12 provided in the test pipe 11 to forcibly drain the water in the priming tank 5 to the underground water tank 2, obtains the lower limit detection output of the water level sensor 8, and then starts the pump. The control panel 9 displays a latched water reduction alarm to check whether or not the water reduction alarm is normally issued.

点検が中断されてしまうという問題があった。(Problem to be Solved by the Invention) However, in such a conventional priming tank alarm device, if a water reduction alarm is issued due to forced drainage of the priming tank 5, the recovery switch 9 of the pump control panel 9 is activated. If the pump performance test is to be performed next, inspection personnel must go to the location where the pump control panel 9 is installed and release the low water latch alarm. However, during this period, the inspection process is interrupted and the inspection takes time. Particularly in recent years, fire extinguishing equipment has adopted unmanned automatic inspection systems, but there has been a problem in that the automatic inspection is interrupted when a low water alarm is latched during a priming tank test.

The test control device 15 outputs a water level recovery signal to the pump control panel 9 and proceeds to the next block 38.
On the other hand, the latch display of the water reduction alarm obtained in the determination block 32 is canceled and the initial state is returned.

データの状態判別を行なう。In this automatic inspection process, when a predetermined inspection cycle is reached, the inspection items, year, month, date, hour and minute are first printed in block 50, stationary data before the inspection is collected in block 52, and judgment block 54 is executed. The status is determined, and if there is abnormal data, the process proceeds to block 56, where an abnormality alarm is issued and the inspection process is ended. If the stationary data is normal, the process moves to execution of the inspection item in block 58, which is, for example, an operational test of the priming tank as shown in FIG. A water reduction detection signal and a water level recovery signal are collected, and a determination block 62 determines the status of these inspection data.
一連の点検処理が終了したならばブロック64で終了処
理、例えば電動弁16の閉制御を行なう。When the series of inspection processes is completed, a termination process, for example, closing control of the electric valve 16, is performed in block 64.

ポンプ性能試験等の点検処理に移行するようになる。Furthermore, after the inspection is completed, stationary data is collected in block 66 and the state is determined in determination block 68. Thereafter, the inspection item end time is printed in block 70, and the next inspection item, for example, the activation control of fire pump 1 is performed. Test piping 1
Inspection processing such as a pump performance test in which the pump discharge pressure and the like are measured while the rated flow rate is flowing in step 1 is started.

ができる。(Effects of the Invention) As explained above, according to the present invention, a water reduction sensor that generates a detection output when the water level decreases below the lower limit is provided in the priming tank, and the pump control panel is controlled based on the detection output of the water reduction sensor. In a priming tank alarm device for a fire pump equipment that latches and displays a low water alarm, a water level recovery sensor is provided that generates a detection output when the water level recovers to a specified water level after the detection output of the water decrease sensor is obtained, and this water level recovery sensor Since the latch display of the low water alarm on the pump control panel is released based on the detection output, the low water alarm is not issued due to forced drainage during the operation test of the priming tank, which is performed as one of the inspection items for fire pump equipment. Even if the low water alarm is latched on the pump control panel, if the water level recovers by stopping drainage from the priming tank and a detection output is obtained from the water level recovery sensor, the low water alarm on the pump control panel will be automatically displayed. The latch display is now released, and there is no need to go to the pump control panel to release the latch of the low water alarm.Also, even during unmanned automatic inspections, the latch display of the low water alarm prohibits pump operation. Automatic inspections such as pump performance tests following priming tank operation tests can be continued without being put away.
