| 9. | In order to change the behindhand state in measurement of natural gas of liaohe oil field , we make the technique reformation , using the normal hole - board , intelligent sensor , natural gas compression factor , arithmetic of volume flux and compensatory technology 为了改变辽河油田天然气落后的计量状态,我们采用标准孔板、智能传感器、国际标准天然气压缩因子、体积流量算法和补偿技术进行天然气计量技术改造。 |
| 10. | Analysis of the test results of the rear - installed cooling system revealed that the overheat problem resulted from the measured cooling air temperature being higher and the coolant flow and transmission oil flow being smaller than the correct design value , and that the wrong location of the hydraulic oil cooler cannot completely meet the need of the cooling system 通过对测试数据进行分析,确定了系统过热的原因,即系统中测试获取的冷却风的温度比设计值高,冷却水和传动油的体积流量比设计值小,而且液压油散热器布置位置错误。 |
