It is discussed in this paper that the ring frame spindle(?) when subjected to forcedvibration due to eccentric rotating load,will be disturbed by a tangential force Tproduced by such factors as the inner hysteresis friction of the spindle blade materialand the lubricating oil effect around the bottom portion of the spindle etc.If theforce T is greater than the inherent damping force in the spnidle,the self-excitedvibration of frequency p with an increasing amplitude will occur and then its movementbelongs in unstable.But the damping force in the spindle system is also excitedto increase simultaneously,so,when these two forces become in equilibrium,then aself-excited vibration with a steady amplitude and of frequency ω_n will occur withthe result that spindle runs at crisis of stability.The spindle blade top will thendescribe a cycloidal locus.This phenomenon appears only when the rotating speedof the spindle is higher than its first critical speed.The chief factors causing theself-excited vibration can now be traced from the character of the experimentallocus of vibration of the spindle blade top.

本文论述环锭纺细纱锭杆在强迫振动过程中受到材料内摩擦效应、润滑油膜效应等形成的切向力的干扰;当该力大于锭杆振动系统特有的切向阻尼力时,锭杆产生频率 p 的增幅自激振动,其运动属于不稳定。但因锭子结构里的阻尼力同时也被激增,当两力成平衡时锭杆就转变为频率ω_n 的等幅自激振动,其运动属于稳定极限情况,锭端轨迹呈现摆线。这种现象只在锭速高于第一临界转速时才出现,并可以根据锭端轨迹的特征来判别自激振动的产生因素。

Based on controlled dispersion flotation and shear flocculation, a new approach for ultrafine particles separation is put forward in this paper, which is called controlled dispersion—shear flocculation flotation technology (CDSFF). By this technology, satisfactory results were obtained on the experimerts of pure apatite (-7.8μm 81.5%) and pure rhodochrosite (-6.9μm 83.67%). A product which contained 0.133%P was obtained from the mixture containing the impurity 0.28%P in ultrafine apatite and rhodochrosite, and...

Based on controlled dispersion flotation and shear flocculation, a new approach for ultrafine particles separation is put forward in this paper, which is called controlled dispersion—shear flocculation flotation technology (CDSFF). By this technology, satisfactory results were obtained on the experimerts of pure apatite (-7.8μm 81.5%) and pure rhodochrosite (-6.9μm 83.67%). A product which contained 0.133%P was obtained from the mixture containing the impurity 0.28%P in ultrafine apatite and rhodochrosite, and the recovery was 66.2%. However, other technologies could not remove apatite as effective as CDSFF. The mechanism of CDSFF was explored in detalls by means of SME. AES., etc. It was also found that the main factor to disperse rhodochrosite strongly was the hydrophilic particle surface on which water-soaked film was formed, but the zeta potential.

Water-wet low permeability reservoir formation is characterized by smell pore radius, high clay content, strong water film effect, and low effective porosity. Thus it is very important to study the mechanism of formation damage and its prevention. According to an integrated study of data from well logging, well testing, SEM technique, and the porous structure of the Jurassic reservoir formation in Maling oilfield, it is confirmed that serious formation damage is resulted due to the effect of undesirable drill fluids employed and migration of fines in the reservoir formation. Thus stable production in the middle-high water-cut stage is very difficult. An application of a combination of various technologies, including the addition of a clay-swelling inhibitor and bactericide, SQ-8, acidizing by fluor-boric acid for deep penetration into the formation, in injection wells; and hydrofracturing and acidization, paraffin and scaling inhibition as well sand wash-out on production wells shows very promissing results.

低渗亲水油层孔径小,粘土含量高,水膜效应强,有效流动孔隙度低,研究油层伤害机理及保护措施非常重要。通过地球物理测井、试井、电子扫描、孔隙结构研究证实马岭油田侏罗系油层存在粘土膨胀迁移,加之泥浆等各种污染对油层损害严重,进入中含水期稳产难度大。在注入水中加入既可防粘土膨胀,又可杀菌的SQ-8药品,用氟硼酸对注水层进行深部酸化;在油井上大搞压裂酸化解堵、防垢防蜡、冲砂洗井等多种工艺改造疏通油层,可获很好效益。
