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.

而机组在进行放水的时候要在周边注意观察水流的具体状况，主要查看水流是否顺畅，看看水流是否出现变小或时快时慢的现象。若出现这些情况，则是说明冷却水中含有杂质，阻碍水的正常流出，此时更好的办法就是将放水开关拆下来，让冷却水直接从机体内流出来。若是发现水流仍然是不顺畅的话，那么这个时候就应该使用铁丝等较硬且细长的钢性物品进行疏通，直到水流畅通为止。

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.

当冷却水停止流出后，我们更好是将静音发电机组再摇转几圈，这样为了将里面剩余的水不易流出的冷却水利用柴油机的震动而流净，等放水结束后，放水开关应处于开启状态，以防止冷却水一时无法流出而冻坏柴油机相应的部件造成不必要的损失。

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.

柴油机的冷却水要是尽心排放的时候要注意排放的步骤，必须要保证将冷却水一次性的排放干净，以免里面的残留水对柴油机造成不必要的损失，以保障机组运转正常。

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.
