Description
本実施形態のポンプ排水機場の冷却設備は、図１に示すように、内燃機関７と、内燃機関７によって駆動され内燃機関７を冷却水Ｗで冷却する冷却水ポンプ１２と、冷却水Ｗを貯留する貯水槽２０とを備えたポンプ排水機場の冷却設備であって、貯水槽２０が、その内部と外部とを連通する連通管１８を備えている。
なお、このポンプ排水機場には、第１の床１の下方に設けられた吸込水槽３と、吸込水槽３内の水を吸い上げて排水する排水ポンプ２とが設置されている。また、上記内燃機関７は、排水ポンプ２を駆動するディーゼル機関である。
As shown in FIG. 1, the cooling facility for the pump drainage station according to the present embodiment includes an internal combustion engine 7, a cooling water pump 12 driven by the internal combustion engine 7 to cool the internal combustion engine 7 with the cooling water W, and the cooling water W. It is a cooling facility for a pump drainage station equipped with a water storage tank 20 to be stored, and the water storage tank 20 includes a communication pipe 18 that communicates the inside and the outside.
The pump drainage station is provided with a suction water tank 3 provided below the first floor 1 and a drainage pump 2 that sucks up and drains the water in the suction water tank 3. The internal combustion engine 7 is a diesel engine that drives the drainage pump 2.
連通管１８の水位は、貯水槽２０より高い位置に保持され、吸込管２３の一端が貯水槽２０の底部近傍まで垂下され、吸込管２３の他端は冷却水ポンプ１２の吸込側に接続されている。
上記冷却水ポンプ１２の吐出側は２つに分岐され、一方は内燃機関７の冷却ジャケット１０の入口に接続されていると共に、他方は減速機８のオイルクーラ１１の入口に接続されている。また、冷却ジャケット１０の出口側とオイルクーラ１１の出口側とは、戻り管２４に接続され、戻り管２４の先端は連通管１８内で開口している。
The water level of the communication pipe 18 is maintained at a position higher than the water storage tank 20, one end of the suction pipe 23 is suspended near the bottom of the water storage tank 20, and the other end of the suction pipe 23 is connected to the suction side of the cooling water pump 12. ing.
The discharge side of the cooling water pump 12 is branched into two, one being connected to the inlet of the cooling jacket 10 of the internal combustion engine 7 and the other being connected to the inlet of the oil cooler 11 of the speed reducer 8. The outlet side of the cooling jacket 10 and the outlet side of the oil cooler 11 are connected to the return pipe 24, and the distal end of the return pipe 24 is open in the communication pipe 18 .
冷却水ポンプ１２の吐出側は２つに分岐され、一方は内燃機関７の冷却ジャケット１０の入口に接続されていると共に、他方は減速機８のオイルクーラ１１の入口に接続されている。また、冷却ジャケット１０の出口側とオイルクーラ１１の出口側とは戻り管３３に接続され、戻り管３３の先端は連通管３１内で開口している。
このように第４実施形態のポンプ排水機場の冷却設備では、定水位弁４２が、拡径部４１内の水位が一定値より下がった際に開いて、補給水源４５からの水を拡径部４１に補給して連通管４０内の水位を一定に保持するので、冷却水Ｗの補給と水位管理とが容易になる。
The discharge side of the cooling water pump 12 is branched into two, one connected to the inlet of the cooling jacket 10 of the internal combustion engine 7 and the other connected to the inlet of the oil cooler 11 of the speed reducer 8. The outlet side of the cooling jacket 10 and the outlet side of the oil cooler 11 are connected to the return pipe 33, and the tip of the return pipe 33 is open in the communication pipe 31.
As described above, in the cooling facility for the pump drainage station according to the fourth embodiment, the constant water level valve 42 opens when the water level in the enlarged diameter portion 41 falls below a certain value, and supplies the water from the makeup water source 45 to the enlarged diameter portion. Since the water level in the communication pipe 40 is kept constant by being replenished to 41, the replenishment of the cooling water W and the water level management are facilitated.
