Adjust the cooling water flow, to avoid the main engine surge or condensation pressure is too high.
调整冷却水流量，避免主机出现喘震或者冷凝压力过高。
If suitable pump and throttle equipment are applied, we can realize the variable flow cooling for main Marine diesel engine.
并且在三通调节阀调节的过程中，主管路流量是变化的，只要采用合适的泵和节流装置，可以实现主柴油机的变流量冷却。
The Reynolds number of the main flow has a relatively small effect on cooling effectiveness, but the cooling effectiveness still increases with increasing Reynolds number as a whole.
主流雷诺数对冷却效率的影响不大，但总体上仍表现出雷诺数越大，冷却效率越高。
