oil transfer pump
解釋
潤滑油輸送泵-
The centrifugal pump for oilfield waterflooding and oil transfer worked with low pump efficiency owing to unstable load and its energy loss is fairly large
油田注水集輸系統離心泵由於載荷經常變化，大多不能在其額定工況點工作，泵效低，且需要用泵出口閥調節流量，產生一定的泵管壓差，造成較大的能量損失。 -
Based on an introduce of the procedure for stipulating the standard of vibration diagnosis of oil transfer pump on an offshore platform, by means of measuring point distribution analysis and selection of diagnosis parameters, the standard for vibration diagnosis of oil transfer pump on qk18 - 1 offshore platform is stipulated by taking the acceleration envelop and vibration velocity as the diagnosis parameters
摘要在介紹制訂外輸泵振動診斷標準意義及步驟的基礎上，通過測點規劃與診斷參數選取，將加速度包絡和振動速度作為制訂標準時的診斷參數，採用改進的統計法制訂了qk18 - 1平臺外輸泵振動診斷標準，應用該標準診斷故障30餘次，表明該標準具有較高的可信度及工程應用價值。 -
It is indicated that, when a two - speed motor is used for driving oil transfer pump, the motor with the characteristic of torque reduction on square rotary speed should be chosen ; the working economy of the variable speed pump is restricted by the characteristic curves of pipeline resistance, and its speed control range is restricted by the pipeline resistance characteristic curve, the pressure head needed by the system and the working characteristic of the pump ; when several pumps work in parallel, the pump with better performance should be changed into speed - variable pump
指出雙速電動機用於輸油泵的調速時，應選用轉矩按轉速平方降低特性的電動機；調速泵的運行經濟性受到管路阻力特性曲線的限制，其調速范圍受到管路阻力特性曲線、系統所需揚程和泵運行特性的限制；在母管制系統中把部分定速泵改為調速泵時，應將性能較高的定速泵改為調速泵。 -
