The adoption of the variable pump is a breakthrough of the water cutting jet which solved the previously problems in suing the home - made products, such as piston pump filling - up, noise, high - consumption of energy, high oil temperature, lowering of piston pump pressure at the beginning of the work which would effect the starting point and the longevity of the high pressure components will be affected by the changes of pressure
採用變量泵是水刀的技術突破，以前用國內柱塞泵，噪音大、不節能、油溫高，柱塞泵在開始工作時壓力會降低，這樣會影響切入點效果，高壓部件會受到壓力的變化而影響高壓部件的使用壽命。 -
The paper analyzes the non - lineal relations of the quantity of heat exchange and water flux of coil exchanger in part - load operating condition, the shortage of deciding the water flux in bypass pipe, the disadvantage that the operating condition of pumps and chiller ca n ' t be met with the load change of the air conditioning system in different operating condition of using pressure - difference bypassing control in primary water pump system. using load control method in the change of the operating condition of primary water pump system can realize that the load change is small and reasonable in the on / off condition of pumps and m m chiller by comparing load control method in primary variable - flow water pump system with pressure - difference bypassing control method, back water temperature control method
本論文從目前空調工程中使用的變流量水系統入手，研究了盤管換熱器在部分負荷下水流量與換熱量的非線性關系，分析了文獻中介紹的旁通管通流能力選擇的不足之處和一次泵水系統採用壓差旁通控制時，工況轉換不能滿足系統控制要求的缺陷；比較了一次泵變流量水系統中壓差旁通控製法、回水溫度控製法、負荷控製法的精確性，並得出了在一次泵水系統的工況轉換時，採用負荷控製法能使冷水機組及其相應水泵在啟停時的負荷變化范圍較小，更符合建築物的冷量需求，節能效果較好的結論。 -
Through analyzing the figure of energy wasting of pump, the quality in pipes is direct proportion of the speed of pump if the speed of pump is reduced. the power of electromotor fell the cube of the speed of pump. so the energy wasting of constant pressure water supply based on variable frequency speed regulating technology is envident less than the traditional mode is used throttle to supply water
分析水泵工況的能耗比較圖，可以看出利用變頻調速實現恆壓供水，當轉速降低時，流量與轉速成正比，功率以轉速的三次方下降，與傳統供水方式中用閥門節流方式相比，在一定程度上可以減少能量損耗，能夠明顯節能。 -
In the light of the pickup current of a submersible electric pump being too large when started at full pressure, a new variable - frequency control system is developed
針對電動潛油泵工頻全壓啟動時存在啟動電流過大等諸多問題，開發出新型電動潛油泵變頻控制系統。 -
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。 -
