論文主要有兩個部分的內容：液壓軸向柱塞泵的故障分析和工程施工企業液壓設備的管理和維護。On the point of system, this paper mainly studies the optimal distribution of load in the machines of irrigation and drainage pumping station, the mathematical model and it ' s solution are studied among the machines in pumping station with two types of axial pump : full regulation or semi - regulation. this paper also studies the problems of the optimal day - operation of pumping station and the economical operation of grading pumping station. at the end, jiangdu pumping station is taken as a practical example to show the theory on economical operation of irrigation and drainage pumping station
本文從系統的觀點出發，以排灌站機組間負荷的優化分配研究為主，分別對全調節和半調節軸流泵兩種泵型的排灌站機組間負荷優化分配的數學模型及其求解方法進行了研究，同時對排灌站最優日運行方式及梯級泵站的經濟運行也進行了初步探索，最後以江都排灌站為例，建立了排灌站經濟運行的實用模型。Not only axial force on pump impeller but also its fluctuation is the biggest among the axial forces on the three working rollers
泵輪的軸向力最大，且變化起伏較大；其他兩輪的軸向力變化較平穩，且數值也較小。The reason for oil leak lies in the sealing problem of bearing box ends of centrifugal pump
離心泵軸頭甩油實質是離心泵軸承箱兩端密封問題。From the experimental results, conclusions of particles " trajectories can be drawn for different densities and operating conditions. three axis segments were acquired, and three operating conditions were picked to study the distribution traits of particles inside the impeller under the different quality and concentration of the particles. based on the results, local wear of pump was forecasted and protecting measures were brought forward
得到運行工況對單個粒子運動軌跡的影響以及不同密度（質量）的單個粒子運動軌跡變化規律；沿水泵葉輪軸向取三個測量斷面，分別在三種不同運行工況下，研究各個斷面間（內）粒子分佈特徵，以及粒子質量和濃度對這種分佈特徵的影響；根據實驗結果，對輸送不同固液兩相流介質時，水泵局部磨損進行了預測並提出了一些防護措施。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。Prototype observation and model experiment indicate that flows in two channels of the discharge passage of an axial - flow pump and a guide vane mixed - flow pump are unequal to each other, there is flow deviation
摘要原型觀測和模型試驗都表明，軸流泵和導葉式混流泵雙孔出水流道兩孔流量不等，存在偏流。Low noise : water pump supported by two low - noise bearings contributes to stable operation without noise basically except slight sound of motor
