ポンプ設備に関する。[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) This invention relates to a fire extinguishing pump equipment that supplies fire extinguishing water to each fire extinguishing equipment in the event of a fire, especially in a nuclear power plant, and particularly in accordance with the Fire Service Act. The present invention relates to fire pump equipment that can suitably carry out performance tests on fire pumps that are required to be conducted once a year.

の規定がある。(Prior Art) In general, fire pumps are used only for fires in which fire extinguishing water is used, and therefore, the Fire Service Act requires confirmation that the performance of the fire pumps is maintained. In other words, for equipment in which a pump is installed in a pressurized water supply system, it is stated in Article 12, Item 7 of the Fire Service Act Enforcement Regulations that ``the pressurized water supply system must have pump performance during rated load operation. It is stipulated that piping equipment for testing shall be provided. In addition, according to item 7 (g) of the same article, [pressurized water supply equipment must be equipped with relief piping to prevent water temperature from rising during shut-off operation.
There are regulations.
これらを基に、従来の消火用ポンプ設備について説明す
る。Based on these, conventional fire pump equipment will be explained.

７に必要な消火用水が供給される。As shown in FIG. 2, a fire extinguishing water supply line 2 is installed in a tank 1 serving as a water source. This fire extinguishing water supply line 2 is connected to a tank 1 through a piping 3, a fire extinguishing pump 4 is disposed in this piping 3, and a check valve 5 and a stop valve 6 are installed on the discharge side of the extinguishing pump 4. The necessary fire extinguishing water is supplied to each fire extinguishing equipment 7.

うその絞り量が設定されている。Incidentally, since it is necessary to fill the area from the discharge side of the pipe 3 to each fire extinguishing membrane width 7 with fire extinguishing water even in times of fire, the fire extinguishing pump 4 is operated even in normal times other than in times of fire. This kind of operation of the fire pump 4 is called a shut-off operation. However, during the shut-off operation of the fire extinguishing pump 4 as described above, the temperature of the extinguishing water rises, so a fire extinguishing water release line 8 is installed to prevent this water temperature from rising. This fire extinguishing water release line 8 is for returning the fire extinguishing water from the discharge side of the fire extinguishing pump 4 in each fire extinguishing water supply channel 2 to the tank 1 through a piping 9, and connects the piping 9 from the upstream side with a flow rate orifice 10, and vice versa. Stop valve 11 and stop valve 12
are arranged sequentially. The flow rate orifice 10 has a throttle amount set so as to return the minimum flow rate to the tank 1 so as not to increase the temperature of the fire extinguishing water.

。Furthermore, a pump performance test line 13 is also installed to test the performance of the fire pump 4 during rated load operation. This pump performance test line 13 leads a test pipe 14 from the discharge side of the fire pump 4, and a stop valve 15 and a flow rate indicator 16 are arranged in this test pipe 14.
The other end of 4 is connected to tank 1. In addition, as shown in FIG.
There may also be a pump performance test line 20 connected to 9.

。In such a pump performance test line 13.20, during the test, the stop valves 6 and 12 are closed and the stop valve 15 is closed, and the discharge am from the fire extinguishing pump 4 is measured by the flow rate indicator 16. At the same time, the discharge pressure of the fire extinguishing pump 4 is measured by a pressure gauge (not shown) installed on the extinguishing pump 4. The performance of the fire extinguishing pump 4 is confirmed from these measured values.
（発明が解決しようとする問題点）
特に原子力発電プラントでは、消火用ポンプ４の水源と
なるタンク１は、他の用途にも使用され、かつ大容借と
なることから、建屋壁１８の外に設置されている。この
ため、建屋壁１８内に設置された消火用ポンプ４は、上
記タンク１から非常に遠くなり、その距離が壬数十メー
トルに及ぶ場合もある。その結果、配管、特に試験用配
管１４の配管長が非常に長くなり設備コストが嵩む。(Problems to be Solved by the Invention) Particularly in nuclear power plants, the tank 1 that serves as the water source for the fire pump 4 is also used for other purposes and requires a large capacity, so it must be installed outside the building wall 18. It is installed in For this reason, the fire pump 4 installed in the building wall 18 is very far from the tank 1, and the distance may extend to several tens of meters. As a result, the length of the piping, especially the test piping 14, becomes extremely long, increasing equipment costs.
また、配管配置上の制約から試験用配管１４との配管を
地中埋設あるいは配管トレンチ内に設置する場合には、
配管が長いと配管敷設に多大なコストが必要となる。In addition, if the piping with the test piping 14 is buried underground or installed in a piping trench due to restrictions on piping arrangement,
If the piping is long, a large amount of cost will be required for laying the piping.
さらに、第３図のポンプ性能試験ライン２０のように、

へ排出できない。Furthermore, like the pump performance test line 20 in Figure 3,
If the test piping 17 can be shortened, the above-mentioned drawbacks can be avoided, but a large amount of water will accumulate in the sump 19. This stored water cannot be immediately discharged to the outside of the building wall 18 because it needs to be deactivated in the case of a nuclear power plant.
そのため、この多聞の貯溜水を処理づる設備が必要とな

Then, the stop valves 6 and 12 are closed. The water in the tank 1 reaches each fire extinguishing equipment 7 as fire extinguishing water by the shut-off operation of the fire extinguishing pump 4, and at the same time, the minimum flow rate to prevent the temperature of this fire extinguishing water from rising is determined by the flow rate A refit 10, the check valve 11, and the stopper. It is returned to tank 1 through valve 12.

Therefore, it is possible to prevent cost increases due to long piping lengths. In addition, even if the test pipe 22 is buried underground, etc., the test pipe 22
Since the piping length of No. 2 is short, a large amount of cost is not required for laying the piping. Furthermore, since the water used for the pump performance test is returned to the tank 1 via the piping 9 of the fire extinguishing water release line 8, there is no need to deactivate the water. From these points, equipment costs can be reduced.
