Q: What kind of pump is usually used as lubricating oil pump? After starting, if such a pump does not build up adequate discharge pressure, what are the possible reasons? (5分)
A: An electric motor-driven positive displacement rotary pump is usually used as a lubricating oil pumps. After starting, if such a pump does not build up adequate discharge pressure may be due to: (5分)
1. Oil viscosity in suction lines is too high, due to inadequate heating. (3分)
2. Excessive air leaks in valve glands, pump glands, or relief valve casing. (3分)
3. Vapor lock in Lube oil pipes due to excessive heating. (2分)
4. Required suction lift being higher than designed. (2分)
1. A fire and wash deck pump should be started as soon as power is available and normally be kept running at all times to give an immediate hose supply in emergency. (5分)
2. Under all normal condition bilges are pumped to the bilge water separator from whence the water effluent is led either overboard at sea, or in port to a storage tank for later discharge more than 25 miles from the coastline. Oil is led to a waste oil tank. (5分)
3. Stand-by units for auxiliary machinery required for propulsion must kept ready. During operation in narrow waters with or without pilot on board, the electrical power supply must be ensured by startup of an extra generator. (5分)
4. Although the fuel was apparently within ISO specification, subsequent in-depth laboratory tests found that the engine-damaging substance in the fuel comprised chemical waste in the form of industrial cleaning solvents. Because of the effects of the added chemical waste, the ship's filters were completely clogged and the fuel pump sticking. At least 10 oil tanker were affected, suffering severe mechanical problems.
