[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention provides a method for manually pumping a pump having a plurality of auxiliary machines to the main machine of, for example, a water supply and sewage plant, a garbage plant, a drainage plant, etc. The present invention relates to a monitoring and operating device that can provide flicker guidance to an operator regarding operating procedures and operating timing.

(Conventional technology) Traditionally, for example, water and sewage plants, garbage.

For pumps that have multiple auxiliary machines for the main machine of plants, drainage plants, etc., each auxiliary machine can be started/stopped and opened/closed individually in order to perform maintenance on the multiple auxiliary machines. Manual operating devices equipped with operating switches are often used.

FIG. 3 is a diagram showing an example of the overall configuration of a pump equipped with this type of monitoring and operating device.

In FIG. 3, the pump 1 to be controlled is equipped with a flow relay 3 that detects the flow of water supplied to the pump 1 for shaft sealing by a water sealing valve 2, which is an auxiliary device. On the other hand, the control device 4 performs interlock control to operate or stop the pump 1 according to the determined contents, and is activated when the interlock/single selector switch 6 provided on the manual operation device 5 is on the interlock side. do.

Also, when the interlocking/independent selector switch 6 is on the independent side,

and an open/close indicator light 8 for displaying the open/closed state of the water sealing valve 2, and further for manually operating/stopping the pump 1.
It is equipped with a stop operation switch 9 and an operation/stop indicator light 10 that displays the operation/stop state of the pump 1.

Next, the operation of such a monitoring and operating device will be described according to the flowchart shown in FIG.

First, selection is made as to whether operation and control will be performed by the control device 4 or the manual operating device 5 using the interlocking/independent changeover switch 6 of the manual operating device 5. That is, first, when the interlocking/independent selector switch 6 is on the interlocking side, the control device 4 determines whether to run or stop, and if it is running, first outputs an opening command to the water sealing valve 2. When the water seal valve 2 is opened, the open/close indicator light 8 lights up in red.

Next, by opening the water sealing valve 2, water from the shaft sealing water reservoir of the pump is supplied to the pump 1, and the flow of the water is detected and the flow relay 3 is activated, which causes the pump 1 to be supplied with water. outputs the operation command, and when pump 1 operates, it starts running/
Stop indicator lamp] O lights up in red, and operation according to the prescribed procedure is completed.

Further, in the case of a stop from the above-mentioned operating state, a stop command is first output to the pump 1, and when the pump 1 stops, the run/stop indicator light 10 lights up in green. However, since pump 1 continues to rotate 12 for a while due to inertia,
After the timer counts up to confirm this complete stop, a close command is output to the water sealing valve 2, and when the water sealing valve 2 is closed, the open/close indicator light 8 lights up in green, and the predetermined procedure is followed. Complete the compliant stop.

On the other hand, when the interlocking/independent selector switch 6 is on the independent side, when the operator arbitrarily manually opens/closes the open/close operation switch 7 using the manual operating device 5, the water sealing valve 2 opens/closes.
When closed, the open/close indicator light 8 displays red/green, and when the run/stop operation switch 9 is operated/stopped, the pump 1 runs/stops, and the run/stop indicator light 10 turns red. /Displays in green.

That is, during normal times, operation and control are performed on the interlocking side, and during testing and adjustment, operation and control are performed on the independent side, which allows arbitrary operation of individual equipment.

However, in the event of an abnormality, etc., it is necessary to manually operate the manual operation device 5 on the independent side according to a determined procedure in the same way as on the interlocking side, and the operator must judge based on the results. Ta. Therefore, compared to interlocking control, manual operation is not only inferior in controllability, but also requires operator skill, and if not performed with the utmost care, it will not work properly. There is a problem that not only is it difficult to start/stop the machine, but also that incorrect operation can lead to damage to the machine.
