The use of silent generator sets generally requires continuous operation, and during continuous operation, the machine itself will generate heat, requiring cooling treatment. When discharging water, due to the low temperature of the external environment of the silent generator set, the cooling water should be discharged 15 minutes after the shutdown when the water temperature drops, rather than being discharged immediately after the shutdown, Otherwise, due to the large temperature difference between the body and the external environment, some components of the silent generator set will deform, thereby affecting the performance of the diesel engine.

而機組在進行放水的時候要在周邊注意觀察水流的具體狀況，主要查看水流是否順暢，看看水流是否出現(xiàn)變小或時快時慢的現(xiàn)象。若出現(xiàn)這些情況，則是說明冷卻水中含有雜質(zhì)，阻礙水的正常流出，此時更好的辦法就是將放水開關(guān)拆下來，讓冷卻水直接從機體內(nèi)流出來。若是發(fā)現(xiàn)水流仍然是不順暢的話，那么這個時候就應(yīng)該使用鐵絲等較硬且細長的鋼性物品進行疏通，直到水流暢通為止。

When the unit is discharging water, it is necessary to observe the specific condition of the water flow around, mainly to check whether the water flow is smooth and whether there is a phenomenon of decreasing or fast and slow water flow. If these situations occur, it indicates that the cooling water contains impurities that hinder the normal flow of water. The best way to do so is to remove the drain switch and allow the cooling water to flow directly out of the body. If it is found that the water flow is still not smooth, then hard and slender steel objects such as iron wire should be used for dredging until the water flow is smooth.

當(dāng)冷卻水停止流出后，我們更好是將靜音發(fā)電機組再搖轉(zhuǎn)幾圈，這樣為了將里面剩余的水不易流出的冷卻水利用柴油機的震動而流凈，等放水結(jié)束后，放水開關(guān)應(yīng)處于開啟狀態(tài)，以防止冷卻水一時無法流出而凍壞柴油機相應(yīng)的部件造成不必要的損失。

After the cooling water stops flowing out, it is best to shake the silent generator set a few more revolutions to make the remaining water inside flow out using the vibration of the diesel engine. After the water discharge is completed, the water discharge switch should be in the open state to prevent unnecessary losses caused by the failure of the cooling water to flow out and freezing the corresponding components of the diesel engine.

柴油機的冷卻水要是盡心排放的時候要注意排放的步驟，必須要保證將冷卻水一次性的排放干凈，以免里面的殘留水對柴油機造成不必要的損失，以保障機組運轉(zhuǎn)正常。

If the cooling water of the diesel engine is discharged with great care, attention should be paid to the discharge steps. It is necessary to ensure that the cooling water is discharged clean at once to avoid unnecessary losses to the diesel engine caused by residual water, in order to ensure the normal operation of the unit.
