  1. The differential equation of pump station start - up transient is established and derived from discharge balance and moment equation of pump unit

    摘要本文從水量平衡及水泵機組力矩方程出發，建立起水泵從起動到同步的微分方程式。
  2. To ensure the charging pump working reliably, the following measures should be adopted : ( 1 ) adopting modified circular casing to reduce the radial force of the impeller and decrease the seal clearance ; ( 2 ) using radical ribs on impeller and helical sealing on shaft to realize minor pressure differential ; ( 3 ) using back pressure stuffing box to ensure sealing under small packing force ; ( 4 ) adopting self - lubricant flexible graphite stuffing for absorption of solids entering in the graphite in case of leaking

    為確保灌注泵可靠工作，提出改進措施： （ 1 ）採用改型環形泵體降低葉輪的徑向力，減小軸封間隙，抑制泄漏； （ 2 ）採用背葉片降低葉片根部壓頭，獲得微壓，使軸封兩端承受較小壓差； （ 3 ）採用螺旋密封降低軸封兩端壓差，在保持微壓的同時避免出現負壓，密封效果更好； （ 4 ）採用反壓式填料密封結構，在很小的壓緊力下，即可保證密封； （ 5 ）採用具有潤滑功效的柔性石墨填料，即使發生軸封泄漏，進入石墨內部的固相顆粒也將隨著石墨的消耗而被鉆井液吸收。
  3. A new novel fully - differential charge pump was designed in this paper, differential input and differential output was used in this circuit

    摘要採用差分輸入和差分輸出方案，設計了一種新型的全差分電荷泵。
  4. By citing distribution piping loss curve, analyses the two commonly used control methods of constant pump head and constant remote circuit differential pressure and considers that control with a constant remote circuit differential pressure is the better

    通過提出輸配管壓損曲線概念，從理論上分析了計量供熱變流量系統循環水泵常用的恆揚程式控制制和恆定最不利環路壓降控制兩種方案，認為恆定最不利用戶資用壓力方案節能效果較好。
  5. Rated for capacities of 10 - 1000 cube meter per hour and differential pressure as high as 10mpa, and capable of handling continuous gas volumes of 100 % slugging, twin - screw type pump provides both the onshore and offshore oilfields a more efficient solution

    以多相泵為核心的多相混輸技術已在石油工業中得到廣泛應用，特別對邊際油田和衛星油田的開發具有顯著的經濟效益。
  6. Because the oil well pump belongs to a simplex reciprocating pump, the most authentic adolph ' s differentical equation of movement of the reciprocating pump valve can be used to reserch the movement of oil well pump valve, but it is well known that this differential equation is singular at the moment when the raising height of the pump valve is zero

    由於抽油泵屬于單缸單作用往復泵，因此可以將目前較權威的阿道爾夫往復泵泵閥運動微分方程用於研究抽油泵泵閥的運動規律，但阿道爾夫泵閥運動微分方程在泵閥開啟初期存在奇點問題。
