气缸摘要：在往复泵中旋转气缸，吸气阀和排气阀是非常重要的部件且是易损部件，它们工作的好坏直接影响往复泵的极限压力、抽气速率、功率消耗以及运行的可靠性。

When the piston to the left side starting from the right end of the move, filled with fluid by squeezing the pump, the suction valve closed, and open the pressure valve and the discharge, this process is known as the process of pressurized water pump.

当活塞从右端开始向左端移动时，充满泵的流体受挤压，将吸水阀关闭，并打开压水阀而排出，此过程称为泵的压水过程。

By using the improved suction parameters containing polished rod stroke,pump plunger diameter and pump depth changed,the mathematical models of simulating system efficiency were developed according to coordination equation of well production.

根据油井产能协调关系，建立了油井抽汲参数调整后的系统效率仿真模型，开发了抽油机井系统效率仿真分析的计算机软件。

In order to prevent damage to the pump must pump discharge pipe into the suction pipe installed between the safety valve.

为了防止泵的损坏，必须在泵的排出管到吸入管之间安装安全阀。

Pump suction pipe and a liquid plus a stent must not be used for pump support.

泵的吸进和没液管道必需另减收架。没有失用泵做支持。

B. water-filled Pump start before the pump casing and suction pipe must be full of water that is because of the presence of air vacuum pumping the population can not be formed and maintained.

b。陈籍水泵在启动以前，泵壳和吸水管内必须先布满水，这是因为有空气存在的情况下，泵吸人口真空无法形成和保持。

This is because the adjustment of the pump suction pipe and installation height, work volume, high cost of construction, and by the construction of environmental constraints, and only in the device when the parking or large maintenance be carried out; the same time, due to process conditions, the adjustment of the pump suction pipe and install a high degree of turn affect the follow-up process, with a knock-on effect.

这是因为调整泵的吸入管路及安装高度，工程量大、施工费用高，并且受施工环境的制约，只有在装置停车或大检修时才能进行；同时，由于工艺条件的限制，调整泵的吸入管路及安装高度又将影响后续工艺，具有连锁反应。

Installed with trolley, electrical startup box, cables, fast connector and suction/drainage hose, this pump may used as movable pump.

本型泵可配套小车、电起动箱、电缆、进出口快速接头、吸排软管等，可作为移动式泵使用。

With the rotating screw and mesh, these seals in the pump suction space evolving, the suction chamber in which liquid enclosure and along the screw axis from the inhalation of room to move continuously push exhaust side, will be closed in the space been discharged in the liquid, like a nut when the screw rotation continued to move forward is the case, this is the basic principle of the screw pump.

随着螺杆的转动和啮合，这些密封空间在泵的吸入端不断形成，将吸入室中的液体封入其中，并自吸入室沿螺杆轴向连续地推移至排出端，将封闭在各空间中的液体不断排出，犹如一螺母在螺纹回转时被不断向前推进的情形那样，这就是螺杆泵的基本工作原理。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
