The fuel oil pressure and forced draught pressure should be matched to ensure good combustion with a full steady flameIn the sentence the word “match” means （）
For a L√Opurifier, if the back pressure of the oil outlet is too high, the interface between oil and water in the bowl will （）.
If the temperature drops low enough, oil will not flow, （） just tell us the temperature.
The term "pour point" is defined as the lowest temperature at which lubricating oils will flow （）.
The pressure difference before and after the lube oil filter indicates （）the filter should be cleaned.
Seamless mild steel is used for steam (also copper for moderate pressure and temperature), h-pair, feed discharge and all oil fuel pressure pipingsAccording to the above sentence, which of the following statements is not true?（）
When centrifuging heavy fuel oil, an important factor to consider is the （） (1) flow rate (2) viscosity of the fuel oil
With respect to the flow of lubricating oil through a diesel engine, the lube oil coolers are located after filters in order to （）.
Thermostatic steam pressure reducing valves are used in the fuel oil service system to control the（）
An axial piston, variable stroke pump is used in a vessels hydraulic steering gearUnder pressure, oil continually leaks out from between the valve plate/cylinder barrel and will（）.
A dirty fuel oil filter is can be detected by （） Ⅰ.fuel oil analysis Ⅱ.observing the pressure drop across the filter
The diameter of the gravity disc is too big It causes oil to flow through the water outlet We changed the disc and no （） is found in the water outlet.
The liquid flowing in the capillary is such that the difference in （） readings taken before the capillary and after it is related to the oil viscosity.
When normal operating pressure is applied to the hydraulic oil used in a high-pressure system, the oil （）.
The remaining oil/water mixture now flows down into the fine separating compartment and moves slowly between the（） in the Turbulo separator.
The operating diesel generators will have their exhaust temperatures, cooling water and lubricating oil temperatures and pressures （） in much the same way as for the main engine.
As for an oil-fired boiler if at a normal steaming condition and water goes out of sight in gauge glasses the action you should take is: （） (1) secure oil to fires (2) increase feed pump pressure
Oil companies in the U.S. are already beginning to feel the pressure. Refinery workers and petroleum-equipment-manufacturing employees are being _______.
末段终点流量增大时，末段起、终点压力都要减小。相反，终点流量减小时，末段起、终点压力都要增大。When the terminal flow increases, the terminal pressure should be reduced. On the contrary, when the terminal flow decreases, the terminal pressure increases.
For a L.Opurifier, if the back pressure of the oil outlet is too high, the interface between oil and water in the bowl will _____.
The remaining oil/water mixture now flows down into the fine separating compartment and moves slowly between the_____ in the Turbulo separator.
As for an oil-fired boiler if at a normal steaming condition and water goes out of sight in gauge glasses the action you should take is: (1) secure oil to fires; (2) increase feed pump pressure.
城市气体消耗少时，向城市的供气量小于干线的流量（也即末段起点的流量），多余的气体积存在末段管路中，使末段的压力上升。When urban gas consumption is low, the gas supply to the city is less than the flow of the trunk （i.e. the flow at the beginning of the last section), and the excess gas is stored in the last section of the pipeline, causing the pressure at the last section to rise.
统计决策法Statistical decision method 使用序贯概率检测（SPRT）的方法对实测的压力、流量进行分析，计算连续发生泄漏的概率，并利用最小二乘法进行泄漏点定位。The measured pressure and flow rate were analyzed with the method of sequential probability detection (SPRT), the probability of continuous leakage was calculated, and the least square method was used to locate the leakage point. 缺点：对仪器的要求比较高Disadvantages： high requirements on instruments
