7. Why is it necessary to install a rotary flap valve or check value in a centrifugal pump that discharge to an elevation of more than 10 meters?
This rotary flap value or check value will prevent trapped water from flowing back below the water level and this trapped water will act as priming water which is responsible in building up of suction pressure during restarting.

8. In which side of an oil cooler should the pressure be kept heavier, the oil side or the water side? Why?
油冷却器哪边的压力应更大些，油的一边还是水的一边?为什么？
The pressure should be kept heavier at the oil side so that in case of tube failure or fracture, oil will flow with the water thus preventing water from entering the lubricating system

9. What will you do beforehand when overhauling a piston of main engine? What should be done after finishing overhauling of machines? 主机吊缸前该做哪些工作？吊缸后该做哪些工作？Before any overhauling work, make sure that all tools and spares required are prepared. Special tools should be marked clearly in order to avoid dislocation. A review of the procedures as per instruction manuals should be carried out. Safety or precaution should also be posted in the vicinity in order that persons are warmed of the ongoing activity.

When sailing in the sea, the ship can pump bilge into sea after the water is processed in the oil water separator with 15ppm detector. When the ship is in the port, if bilge is too much, it can be discharged into the onshore with the help of the agent. If bilge water is really too much, it can be pumped into the bilge water hold tank for temporary storage

13. What are the possible reason for abnormal high exhaust temperatures, and abnormal low temperature of the main engine?
柴油机排气温度过高或过低是什么原因？
Abnormal high temperature is possibly caused by overloading, timing delay for injection, leakage in fuel injector or valve and fouling of the fuel injector valves, and low pressure in scavenging.
柴油机排气温度过高可能是由于负荷太大、喷油太迟、喷油器和气阀泄露、气口太脏，以及扫气压力太低等原因造成的。Abnormal low temperature is possibly caused by low loading, early injection, clog in fuel injector, insufficient oil supply, broken spring in the high-pressure oil pump or the dead plunger.
柴油机排气温度过低可能是由于负荷过低、喷油太早、喷油器堵塞、油量供应不足、高压油泵弹簧断掉或柱塞卡死等原因造成的。
