The current field in the centrifugal pump , which includes entrance pipe , impeller , volute and outlet pipe , is simulated and analyzed in this paper , and the solid particle trajectory is computed by using lagrange method under the flow field . some conclusions about the particle trajectory are given and validated by the engineering practices 本文研究了渣漿泵內吸入口段、葉輪區、蝸殼以及擴散管延長段的清水流場的流動狀況,并且在此基礎上用拉格朗日法模擬了固體單顆粒的運動軌跡,最后得到規律性的結論,與實際工程相吻合。

It uses the encouragement of step wave or other impulse current field source to produce the transition process field in earth . in the moment of shutting the power it produce the volute alternating electromagnetic field . from the abnormity of measuring the attenuation character of the second induction electromagnetic field , which produced by underground medium with time change , the conductive capacity and the position of the underground non - homogeneous substance can be analyzed 瞬變電磁法( transientelectromagneticmethod )是一種時間域的電磁勘探方法,利用階躍波或其它脈沖電流場源激勵,在大地產生過渡過程場,斷電瞬間在大地中形成渦旋交變電磁場,測量這種由地下介質產生的二次感應電磁場隨時間變化的衰減特性,從測量得到的異常分析出地下不均勻體的導電性能和位置,從而達到解決地質問題的目的。

In the first part , the method of velocity coefficient was used to design a 100mm diameter impeller with five single - arc - cylinder blades , and the method of velocity moment was applied to design the volute “ s cross - section . the volute “ s cross - section is a rectangle , which was designed as a whole structure with the front shroud of the pump . a special lighting window was designed on the side 在第一部分工作中,設計了一個帶半開式葉輪的微型泵:葉輪外徑100mm 、共5片單圓弧圓柱形葉片;蝸殼采用速度矩法設計,內為矩形斷面,和泵殼前蓋板為一整體、透明結構,側面專門設計一個打光窗口。

It requires more even airflow and avoids the tremble of the compressor and the instability of gas turbine . at the same time , the dimension of the inlet volute must be as small as possible , so that the gas turbine can work well 一方面,它要求流經進氣蝸殼的氣流盡量均勻,以免造成壓氣機的喘振和整個動力裝置性能的不穩定;另一方面,要求進氣蝸殼結構尺寸在保證要求的前提下盡量小,有利于機艙的布置。

The velocity - coefficient method was used to design a 180mm diameter impeller with five single - arc - cylinder blades . the exit angle and inlet angle of the segment are 35 . 1 and 36 . 0 in degrees respectively . the shape volute ' s cross - section is the rectangle 該葉輪采用速度系數法設計,轉輪外徑180mm ,共有5張單圓弧圓柱形葉片,其出口安放角、進口安放角分別為35 . 1度、 36 . 0度。

Although the structure of the pump is different from the normal one , the performance of the pump can be measured and the internal flow fields in the volute and impellers can be investigated by using piv easily 這樣,該實驗裝置既能進行水泵性能試驗,又滿足piv的測試要求。本文在轉速為1200r / min工況下,進行了水泵的外特性試驗,得到了水泵的性能曲線。

By the multiple objective optimization , the diffusion angle of the ventilator volutes with high efficiency , low noise and high total pressure of the ventilators was calculated and selected according to the experimental data 摘要根據實驗數據,采用多目標最優化的方法,對效率高、噪聲小、全壓大等性能指標皆好的通風機蝸殼擴壓角進行了理論計算選擇。

The base discharge elbow shall meet the slide bracket by method of a three point , wedged engagement that is uniquely designed to match the volute flange to the stationary elbow to eliminate head losses 排泄彎頭基座應該與滑動平臺相匹配,所采用的連接方式應該為三點楔入接合式,并專為蝸形法蘭與固定彎頭特別設計,能夠達到消除揚程損失的目的。

Then a specific ventilator was chosen as an example , and by the method of objective functions , the diffusion angle of its volute was calculated and analysed to optimize the operating performance of the ventilator 并針對有具體用途(使通風機的流量達到額定值)的通風機,采用目標函數法對通風機綜合性能指標最優化的擴壓角進行了算例分析。

Sow series single stage double entry pump is a horizontally split volute centrifugal pump , mainly used to handle clean water or liquids similar to water in physical and chemical properties , temperature not above 105 Sow系列單級雙吸泵系水平中開蝸殼式離心泵,主要供輸送溫度不高于105的清水或理化性質類似于水的液體。

Suitable for producing double twist spring , straight spring , pagoda - shaped draught spring , rectangular spring , wires with various shapes , volute spring and other special - shaped springs 五、適用于生產雙扭簧、直形簧、寶塔拉簧、矩形簧、線材成形、鋼皮渦簧及各種花式簧、異形簧等。

It is based on the application of explicit finite element ( fe ) analysis codes to study volute vane behavior under metalwork impact conditions 根據實際葉片的特點設計了葉片金屬塊撞擊的試驗件,按照不同的條件進行了撞擊試驗。

This paper is about the experiment and numeric simulation of the metalwork impact on the volute vane of the particle separator 與此同時,帶來的影響是粒子分離器本身可能受沙石和硬物的撞擊,其強度與壽命將受到很大影響。

In the second part , in terms of the youth actualities , to talk about the effect on the volute of the youth 第二部分,結合青年思想的實際情況,具體論述大眾文化對青年身心健康的影響。
