Cargo and ballast pump speed control system 货油及压载泵转速控制系统
Study on the cavitation occured during transferring liquid cargo with high vapour pressure by centrifugal pump 离心泵输送高蒸气压液货发生汽蚀问题的探讨
At last, the mathematic models of cargo pump, re-liquefied plant and cargo handling piping network are simulated on PC. 最后,文章对货泵、再液化装置和货物管网的货物装卸的操作过程进行了计算机计算仿真。
This paper describes the condition of the damaged cargo gear pump used in chemical tanker, gives a new repairing technique. 文章描述了某轮双螺杆货油泵的损坏状况,具体分析了产生故障的原因,提供了相应修理方案。
The application of twin screw spindle cargo oil pump on oil supply ship 双螺杆式货油泵在供油船上的应用
Second, classic hydrodynamic theory, least square method and difference method are exerted to cargo pump's mathematic model for theory analysis and calculation. 其次,运用经典流体力学理论对液化气船舶的货泵进行了理论分析,利用最小二乘法和插分法对货泵的工况点进行了求解;
The Safety Function is that when the level in cargo tank is too high ( equal to or more than 98.7% of the whole volume of the cargo tank), start the two cargo pumps in the bottom of two discharging pump towers to discharge LNG. 安全功能为:当液货罐液位过高(达到并超过液货罐总容积的98.7%)时,启动泵塔中两个卸货泵井底部的液货泵排出液货LNG。
Secondly, mathematical models were established for the major component of the liquid cargo operating system, such as the cargo tank, cargo piping, stripping pump, compressor, heater, etc and presented calculation process. 其次,对液货操作系统的主要组成部分:液货舱、货物管路、扫舱泵、压缩机、加热器等建立数学模型,并给出了主要的计算流程。
Valve remote control system can control the hydromantic driving unit, valves, gather data from cursors. It can also control cargo pump and ballast pump. 阀门遥控系统采集阀门以及传感器数据,控制液压动力单元、液压阀门,对液货泵及压载泵等进行控制。
