汽油机水泵是一种离心泵。离心泵的工作原理是在泵内充满水的情况下，发动机带动叶轮旋转，从而产生离心力，叶轮槽道中的水在离心力的作用下甩向外围流进泵壳，于是叶轮压力降低，这个压力低于进水管内压力，水在这个压力差的作用下由吸水池流入叶轮。这样水泵可以不断地吸水不断地供水了。主要用途：农业排灌，工业排水等装置。
汽油机比柴油机轻巧，制造成本低，噪声较小，低温起动性较好，但热效率较低且燃料消耗率大。
汽油机是用汽油作燃料的一种电火花点火式内燃发动机。汽油机一般采用往复活塞式结构，由本体、曲柄连杆机构、配气系统、供油系统、润滑系统和点火系统等部分组成。
小型汽油机一般系统组成：
（1）曲轴连杆系统：包括活塞、连杆、曲轴、滚针轴承、油封等。
（2）机体系统：包括缸盖、缸体、曲轴箱、消声器、防护罩等。
（3）燃油系统：包括油箱、开关、滤网、沉淀杯和化油器等。
（4）冷却系统：包括冷却风扇、引风罩等。有些背负式喷雾喷粉机在大风机后蜗壳上开冷却口，由引风罩引出冷却气流，需要单独的冷却叶轮。
（5）润滑系统：二冲程汽油机采用汽油与润滑油组合的混合油润滑与供油系统合用。四冲程汽油机润滑与供油分开，曲轴箱配有润滑油油面尺。
（6）配气系统：四冲程汽油机由进、排气门，摇臂，推杆，挺杆及凸轮轴等组成。二冲程汽油机没有进、排气门，而是在汽缸体上开有进气口、出气口和换气口，利用活塞上下运动来开启或关闭各气孔。
（7）启动系统：有两种结构，一种是由启动绳和简单启动轮组成；另一种是回弹式启动结构，带有弹簧结合齿和防护罩等。
（8）点火系统：包括磁电机、高压线、火花塞等。其中磁电机有两种：有触点式带跳火架结构和无触点式电子点火线路。

and clasped me round the neck. This she was doing when
Peggotty came running in, and bounced down on the ground
beside us, and went mad about us both for a quarter of an hour.
It seemed that I had not been expected so soon, the carrier
being much before his usual time. It seemed, too, that Mr. and
Miss Murdstone had gone out upon a visit in the neighbourhood,
and would not return before night. I had never hoped for this. I
had never thought it possible that we three could be together
undisturbed, once more; and I felt, for the time, as if the old days
were come back.
We dined together by the fireside. Peggotty was in attendance
to wait upon us, but my mother wouldn’t let her do it, and made
her dine with us. I had my own old plate, with a brown view of a
man-of-war in full sail upon it, which Peggotty had hoarded
somewhere all the time I had been away, and would not have had
broken, she said, for a hundred pounds. I had my own old mug
with David on it, and my own old little knife and fork that wouldn’t
cut.
While we were at table, I thought it a favourable occasion to tell
Peggotty about Mr. Barkis, who, before I had finished what I had
to tell her, began to laugh, and throw her apron over her face.
‘Peggotty,’ said my mother. ‘What’s the matter?’
Peggotty only laughed the more, and held her apron tight over
her face when my mother tried to pull it away, and sat as if her
head were in a bag.
‘What are you doing, you stupid creature?’ said my mother,
laughing.
‘Oh, drat the man!’ cried Peggotty. ‘He wants to marry me.’
‘It would be a very good match for you; wouldn’t it?’ said my
Charles Dickens ElecBook Classics
David Copperfield
mother.
‘Oh! I don’t know,’ said Peggotty. ‘Don’t ask me. I wouldn’t have
him if he was made of gold. Nor I wouldn’t have anybody.’
‘Then, why don’t you tell him so, you ridiculous thing?’ said my
mother.
‘Tell him so,’ retorted Peggotty, looking out of her apron. ‘He
has never said a word to me about it. He knows better. If he was to
make so bold as say a word to me, I should slap his face.’
Her own was as red as ever I saw it, or any other face, I think;
but she only covered it again, for a few moments at a time, when
she was taken with a violent fit of laughter; and after two or three
of those attacks, went on with her dinner.
I remarked that my mother, though she smiled when Peggotty
looked at her, became more serious and thoughtful. I had seen at
first that she was changed. Her face was very pretty still, but it
looked careworn, and too delicate; and her hand was so thin and
white that it seemed to me to be almost transparent. But the
change to which I now refer was superadded to this: it was in her
manner, which became anxious and fluttered. At last she said,
putting out her hand, and laying it affectionately on the hand of
her old servant,
‘Peggotty, dear, you are not going to be married?’
‘Me, ma’am?’ returned Peggotty, staring. ‘Lord bless you, no!’
‘Not just yet?’ said my mother, tenderly.
‘Never!’ cried Peggotty.
My mother took her hand, and said:
‘Don’t leave me, Peggotty. Stay with me. It will not be for long,
perhaps. What should I ever do without you!’
‘Me leave you, my precious!’ cried Peggotty. ‘Not for all the

world and his wife. Why, what’s put that in your silly little
head?’―For Peggotty had been used of old to talk to my mother
sometimes like a child.
But my mother made no answer, except to thank her, and
Peggotty went running on in her own fashion.
‘Me leave you? I think I see myself. Peggotty go away from you?
I should like to catch her at it! No, no, no,’ said Peggotty, shaking
her head, and folding her arms; ‘not she, my dear. It isn’t that
there ain’t some Cats that would be well enough pleased if she did,
but they sha’n’t be pleased. They shall be aggravated. I’ll stay with
you till I am a cross cranky old woman. And when I’m too deaf,
and too lame, and too blind, and too mumbly for want of teeth, to
be of any use at all, even to be found fault with, than I shall go to
my Davy, and ask him to take me in.’
‘And, Peggotty,’ says I, ‘I shall be glad to see yo...应具备符合《电石行业准入条件》中工艺装备、环境保护、能源及资源消耗和资源综合利用等要求，以及无开放式电石炉等条件3寸汽油机水泵价格 汽油机压井水泵 汽油排水泵 吴各省、自治区、直辖市发改委或经委要会同等有关部门，对通过公告企业保持电石行业准入条件情况进行定期监督检查3寸汽油机水泵价格 汽油机压井水泵 汽油排水泵 吴
上半年亚太股权筹资创纪录印度并购交易活跃
据美国道琼斯公司旗下的金融资讯网站‘市场观察’4日报道，今年上半年，亚太地区（不包括日本）股权筹资额了创纪录的567亿美元，筹资额排在前三名的依次是内地、韩国和香港。‘市场观察’援引汤姆森财经资讯公司发布的一份新研究报告说，今年上半年，不包括日本在内的亚太地区共完成351笔公开市场新股发行交易（IPO），筹资总额271亿美元。报告还显示，在并购交易方面，印度是今年上半年亚太地区活跃的市场。美国经济降温需求下降麦格理看淡亚洲外销类股
麦格理证券日前表示，由于美国经济降温而令亚洲外销商品的需求下降，投资人下半年应尽量避开亚洲外销类股票。麦格理证券亚洲证券策略师罗克斯表示，预计行业分析师会开始调降亚洲外销类股下半年的盈利预测。他建议投资人售科技股，转而投资银行、电讯以及公用设施股。罗克斯同时下调了今年亚洲(除日本外)企业每股收益预测的增幅，由12月预测的15.4%降为14.4%。他还表示，将把韩国和等依赖科技产品外销的经济体的股票评级下调至“跑输大盘”。罗克斯说，美国经济增长减速势必会对相关企业盈利带来冲击，尤其是亚洲的出口导向型科技企业。罗克斯看好亚洲金融类股，他预计亚洲地区金融机构每股收益今年有望增长8.3%，明年更可达11.6%。罗克斯的股票是星展银行，此外他还看好移动通信(香港)。
滞胀或并存Fed利率决策将成美国经济大
新近接受调查的经济学家表示，不论通货膨胀上升还是住房市场放缓都不会导致美国经济严重脱离增长轨道，不过，它们的确会让联邦储备委员会(Fed)贝南克(BenBernanke)的日子很不好过。《华尔街日报》6月中旬对56位经济学家所作的预测调查显示，美国经济正处在十字路口，经济增速看来即将放慢，而通货膨胀却有加速迹象。出于这种想法，许多经济学家对Fed下一步会在短期利率方面作何行动划上了一个的问号。在他们看来，Fed现在左右为难，决定什么更重要：是应该通过加息遏制价格上涨势头，还是应该停止加息、让经济继续保持一定的增长速度。 雷曼兄弟(LehmanBrothers)美国席经济学家伊桑?哈里斯(EthanHarris)说，我们认为Fed正在左右权衡这两个问题，也是增长放缓和通胀加剧的问题。现在还很难猜测它会处理哪个问题。这次对56位经济学家的调查得出的平均预测是，2006年下半年，美国国内生产总值（剔除通胀因素之后的）实际增幅折合成年率将降至2.9%。而今年一季度的增幅是5.6%，二季度预计是在2.8%，据此计算，上半年增幅应在4.2%。经济学家还预测，到明年上半年，经济增幅将进一步放缓至2.7%，是2003年年中以来的低水平。周一公布的新数据显示，二季度制造业虽在继续扩张，但速度的却有所放缓，建筑类支出也是同样情况。本月28日，政府将公布二季度GDP初步数据。接受调查的经济学家预计，未来12个月内，平均每月新增非农业人数在140,000左右。如以此推算，明年5月份时，失业率将从今年5月的4.6%升至4.8%。至于消费价格的走势，四分之三的受访者预计，消费价格还将有很大上升空间，直到经济放缓终导致通货膨胀开始回落。他们预测，到11月份，消费价格将较上年同期上升3.1%，此后10年的平均水平将在2.5%。本周五，劳工部将公布6月份业数据。经济增长放缓和通货膨胀上升让经济学家对此前的良好预期感觉不太肯定。总体上看，有63%的受访者对他们的GDP预测值表示有信心，而一年前的这个数字是68%。此外，受访者预计明年出现衰退的概率是20%，比去年同期的数字高出了一倍。 一个突出的问题是：由于能源价格居高不下、消费者债务沉重以及住房市场过度扩张等因素，美国经济很有可能因为意外打击而一蹶不振。WrightsonICAP席经济学家娄?克兰代尔(LouCrandall)说，目前美国经济压力巨大，一有意外很容易受到打击。经济学家们列举了从禽流感大面积爆发到地缘政治动荡激发能源危机等多项可能发生的。不过，让他们担心的还是，Fed会将利率抬得过高、从而导致美国经济陷入衰退。在一位曾以反通胀而著称的新的带领下，Fed官员对打击通货膨胀热情正高。56位受访者中有12人将货币政策决策失误列为未来12个月美国经济可能面临的大。对Fed利率决策的担忧同利率一样与日俱增：在《华尔街日报》过去两项调查中，受访者总是低估了央行的加息程度。上周，Fed将联邦基金目标利率上调至5.25%，这已是该央行连续7次加息。 “利率的上升已经出我的预期，我越来越担心他们有些行动过激，”瑞银(UBS)的席美国经济学家莫里?哈里斯(MauryHarris)说。受访者预计联邦基金目标利率在年底前5.50%的可能性为50%；预计6.25%的利率水平会导致衰退。很多处在经济扩张中的央行都会面临类似的两难选择。为经济增长，Fed曾经在很长时间内维持利率水平，旨在压低资金成本并提振信贷。现在，稳步抬升利率似乎已经起到冷却经济的作用。当出央行启动加息周期时，基准利率不过1%。进一步加息，利率将升至多数经济学家认为可能抑制经济增长的程度。在他们看来，在Fed为抵御通货膨胀继续加息的同时，他们也将牺牲一定的经济繁荣。而至于牺牲的程度，每个人都只能猜测，因为利率决策的影响有时要在两年后方能显现。Fed在本次政策会议上一该往日做法，并未暗示未来的政策倾向。Fed在政策会议后的声明中称，“未来的加息程度和时机”将取决于通货膨胀和经济增长两方面的演变。当然，多数经济学家对于贝南克(Bernanke)寻求平衡的能力给予了较高评价。他们对这位新任目前为止的利率政策给出了“B+”的分数，56位
