The reason is big house passenger car making pump is outfit go up in big pump, because make pump and big pump,be gear drive; tear open loose big pump should be torn open above all when installing dozen of pump, ability hit pump get off, as a result of temporarily unwary, after installing dozen of pump, forget a big pump screw to tighten solid, cause car thereby when ignition is frame-up, cause undesirable app

原因是大宇客车打气泵是装在大泵上，因为打气泵和大泵是齿轮驱动；拆装打气泵时首先要拆松大泵，才能把打气泵取下，由于一时疏忽，装好打气泵后，忘记把大泵螺丝紧固，从而引起车辆点火不正时，引发不良现象。

Fire pump, bilge pump, ballast pump, oil discharge pump, heat exchange etc. and some other pump service for the main engine, assistant engine, boiler.

为主辅机，锅炉服务的各种泵以及消防泵，舱底泵，压载泵，货油泵，热交换器等。

Using Latin square test, the effect of geometrical parameters on the characteristics of non-overload sewage pump was studied, and the effecting principle of geometrical parameters on efficiency, maximum brake horsepower and its location were researched, the major and minor factors affecting these performance were found out by way of variance analysis, the correction of equation on maximum brake horsepower and its location were also tested.

用正交试验法研究了各几何参数对无过载排污泵性能的影响，探索了各几何参数对效率、最大轴功率值及其位置的影响规律，并通过方差分析找到了影响这些性能的主要因素和次要因素，验证了无过载排污泵最大轴功率值及其位置公式的正确性，根据试验结果对模型泵提出了进一步设计方案，本试验结果对无过载排污泵水力设计有一定的参考价值。

Multiple class partial flow pump:(1)The head coefficient value should be low in the single class partial flow pump.(2)The total area of larynx wicket gate should be 200% the single classs larynx area.

2对于多级部分流泵：(1)部分流多级泵扬程系数的取值应比单级部分流泵的取值偏低一些；(2)部分流多级泵导叶总的喉部面积应是单级部分流泵喉部面积的两倍。

The main production of multi-purpose suction pump Product specifications diversified, hassand suction pump,ùsand suction pumps, sand°suction pumps, ten-inch sand suction pumps, suction powerful quality.

主要生产产品多功能吸泵规格多元化，有四寸吸沙泵、六寸吸沙泵、八寸吸沙泵、十寸吸沙泵等，吸力强大，质量上乘。

Based on the analysis on the causes of frequent leak of liquid sulphur trioxide pump, some improvement was taken for its mechanical sealing construction.

分析液体三氧化硫泵屡遭泄漏的原因并对泵的机械密封进行改进，同时根据液体三氧化硫易气化和固化从而不利于泵密封的特性，加强工艺管理，特别是在开停车和泵的切换操作过程中，通过适当的伴热、空气吹扫和蒸汽加热，保证三氧化硫始终处于液态，使泵具有良好的机械密封性能。

Multi-function string which combines hollow rod electric heating, adding hot waste water above pump, adding hot waste water below pump, hot water circulation below pump, using sinker bar below pump, and borehole chemical viscosity reduction has been used selectively according to different production requirement and reservoir conditions.

采用能实现空心杆电加热、泵上掺热污水、泵下掺热污水、泵下热水循环泵上掺入、泵下配置加重杆、井筒化学降粘等多功能综合管柱，适应各种不同生产要求，根据油层条件，选取一种或多种组合、配套。

Screw pump the working principle is: screw pump work, the liquid after being inhaled into the screw pump shell and sealed by Wai space, when the initiative screw rotation, the screw pump seal volume in the squeezed increase Luoya Screw pump pressure, and along the axial movement.

螺杆泵的工作原理是：螺杆泵工作时，液体被吸入后就进入螺纹与泵壳所围的密封空间，当主动螺杆旋转时，螺杆泵密封容积在螺牙的挤压下提高螺杆泵压力，并沿轴向移动。

Company Products Main Series: pipeline pump, centrifugal pump, sewage pumps, self-priming pump, liquid pump, fire pump and so on.

公司产品主要系列：管道泵、离心泵、排污泵、自吸泵、液下泵、消防泵等。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
