常规作业

For a long period, Xinxiang factory always adopted common design and analogy design, so result in products with such characteristics include ponderosity, absonantconfiguration, high cost and low efficiency, also caused interference of link mechanism during operation, and induced the dig force not reached the nominal specification.

长期以来，由于该厂对工程机械的设计一直采用常规设计和类比设计为主的设计方法，故造成其产品不但粗大笨重、结构不协调、成本高及生产效率低，而且还造成装载机的工作装置在作业过程中连杆机构的相互干涉，致使装载机的掘起力未能充分体现出发动机的动力。

针对胜利油田水平井修井技术还不十分完善、大部分作业沿用直井的常规修井工具的现状，研制了利用提放方式实现退出的可退式打捞工具，并形成了本体打捞和对扣打捞两种系列。

Normal bogies of trunk locomotives are not fitted to the switching services on the curve line with small radii.

常规的干线机车转向架不适应小半径曲线上的调车作业，随着机车轴重的增加，这一问题将更加突出。

The production line for both three layer PE pipe and epoxy powder inner anticorrosion pipe came from the reformation of an original production line of three layer PE pipe. The main problems to have been solved are as follows, convert the conventional spray gun deflector into two parts of diversion nozzle and gun wick to suit for different pipe diameters; adopt two stage retrieval equipment to increase powder retrieval rate and improve work environment; enlarge the calibres of gas jet and Venturi pump jet to increase powder output 20% above to ensure the spry coating thickness; design gun pushing device to raise automatic production level.

三层PE管和环氧粉末内防腐管兼容生产线是在三层PE管生产线的基础上改造而成的，主要解决了如下技术问题：将常规使用的喷枪导流体改成导流嘴和枪芯两部分，以适应喷涂不同直径钢管的需要；采用双级回收装置，提高粉末回收率，改善作业环境；加大一次气喷嘴和文丘里泵喷嘴的口径，使出粉量增加20%以上，从而保证涂层喷涂的厚度；设计推枪装置，提高生产的自动化程度。

Our company lies in Guangzhou, near to the Wenchong Shipyard, Guangdong New China Shipyard and several main ports, has a strong engineering team with rich seagoing vessel serving experiences, we are good at supplying general deck and engine stores, safety equipments, hatch cover series, anchor chain, wire ropes and hawsers, marine lamps, English seacharts and publications, marine valves, main/aux engine spare parts, provisions etc. And offer ship repairing, tank cleaning, engineering works etc.

我们公司位于广州，与文冲船厂、广州国际造船厂和广州各主要港口毗邻，拥有多年远洋船舶供应和服务经验，专门为来往于中国各主要港口的船舶提供各项优质的报务，包括供应伙食、厨房用具、船员福利用品、常规五金工具、气电动工具、船用钢丝绳缆绳钢材、舱盖配件、救生消防设备、船用阀门接头、船用电器、盼更垫片等，并可提供主/辅机备件等，清舱作业等。

In operation, the downhole devices will be laid down with tubings which will move up and down using the operation machine. Since the injection head can rotate in the determined speed, the rotating flow, compared with the conventional stable axial flow, can prevent the sands from depositing in the horizontal annular and washing the screen. The jet from high-efficiency jet nozzle will wash the screen directly with concentrated hydro-power. The working fluid can be clean water, without damage to the formation.

作业时用油管下入该井下装置，利用作业机带动油管上下移动，由于喷头可按照既定速度旋转，返回流体在水平段由常规的平稳轴向流动变为旋转流动，既可实现对防砂管的全方位解堵，又能避免砂粒沉积；高效喷嘴产生的射流直接对着防砂管冲击，能量集中；工作介质为清水，不会对地层带来二次污染。

The use of differential pressure compensator resolved the difficult problem that partial fan was damaged when fiexible air duct was withdrawn in long blind heading series ventilation , which renewed the mutil partial fan ventilating method.

压差补偿器装置成功地解决了长独头掘进串联通风中柔性风筒被抽出时局部扇风机吸瘪的技术难题，刷新了长独头掘进多台局部扇风机串联通风的常规方法，极大地改善了长独头掘进工作面的生产作业环境。

The pipe string includes double hydraulic cylinder with anchorage packer、double hydraulic cylinder without anchorage packer、releasing tool、reversing valve and centralizer.

胜利油田目前采用的常规换层采油管柱工作寿命短，且需多次起下管柱实现换层，施工程序复杂，作业成本高。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
