Abstract

Dalam siklus PLTU, sistem Air Penambah berfungsi untuk memenuhi kebutuhan penambahan air di hotwell kondenser ketika terjadi kebocoran kebocoran atau gangguan lainnya. Make up Water Transfer Pump merupakan pompa yang berfungsi untuk memompa air dari make up water tank menuju hotwell kondenser sebagai air penambah. Pada saat gangguan unit, kebutuhan air penambah untuk mengisi hotwell kondenser akan meningkat. Sehingga aliran air penambah akan semakin besar, hal ini menyebabkan tekanan pada make up water transfer pump turun. Ketika tekanan turun maka kecepatan aliran air menuju hotwell akan berkurang sehingga level air di hotwell kondenser tidak akan terpenuhi. Oleh sebab itu operator harus segera mengoprasikan pompa yang standby. Karena pengoperasian masih secara manual, terjadi keterlambatan pengoperasian standby pompa yang mengakibatkan tidak terpenuhinya kebutuhan air penambahpada hotwell condenser. Oleh sebab itu make up water transfer pump harus di tambahkan pressure switch untuk sistem kontrol auto start agar ketika tekanan turun maka pompa standby dapat langsung beroperasi dan kebutuhan air di hotwell kondenser akan terpenuhi.

In the cycle of the power plant , water system enhancer serves to meet the needs of Hotwell addition of water in the condenser when the leakage or other disorders. Make up Water Transfer Pump is a pump that serves to pump water from the make -up water tank towards Hotwell condenser as water enhancer. At the time of interruption unit , the water needs to fill Hotwell condenser enhancer will increase. So that the water flow will be even greater enhancer , it puts pressure on the make-up water transfer pump drop. When the pressure drops , the speed of the water flow towards Hotwell will be reduced so that the level of water in the condenser Hotwell will not be met. Therefore, the operator must immediately operate the pump standby. Because the operation is still manually , there is a delay operation of the standby pump resulting in unmet needs in Hotwell condenser water enhancer. Therefore, make-up water transfer pump pressure switch should be added to the control system auto start so that when the pressure drops , the standby pump can be directly operated and Hotwell condenser water needs will be met .
