武漢耀泰**： 德國(guó)博世力士樂(lè)BOSCH Rexroth泵、閥、馬達(dá)，美國(guó)威格士Vickers泵、閥，萬(wàn)福樂(lè)、意大利阿托斯ATOS、美國(guó)ASCO
         
柱塞泵，是由電動(dòng)機(jī)提供泵的動(dòng)力，經(jīng)鼓型齒聯(lián)軸器帶動(dòng)減速機(jī)轉(zhuǎn)動(dòng)。由減速機(jī)減速帶動(dòng)曲軸旋轉(zhuǎn)。通過(guò)曲柄連桿機(jī)構(gòu)，將旋轉(zhuǎn)運(yùn)動(dòng)轉(zhuǎn)變?yōu)槭诸^和柱塞為往復(fù)運(yùn)動(dòng)。當(dāng)柱塞向后死點(diǎn)移動(dòng)時(shí)，泵容積腔逐步增大，泵腔內(nèi)壓力降低，當(dāng)泵腔壓力低于進(jìn)口壓力時(shí)，吸入閥在進(jìn)口端壓力作用下開(kāi)啟，液體被吸入；當(dāng)柱塞向前死點(diǎn)移動(dòng)時(shí)，泵腔內(nèi)壓力增大，此時(shí)吸入閥關(guān)閉，排出閥打開(kāi)，液體被擠出液缸，達(dá)到了吸入和排出的目的。

高三了，要付出很多辛苦，要承受很多壓力，知道嗎,只要堅(jiān)持下去，你就能創(chuàng)造自我，超越自我。

　　夜深人靜，萬(wàn)籟俱寂，寺廟里的兩塊石頭在小聲交談。鋪在地上當(dāng)臺(tái)階的一塊石頭向被雕成佛像的另一塊石頭抱怨說(shuō)：咱倆從一座山來(lái)，瞧你現(xiàn)在多風(fēng)光，每天都有那么多人跪在你腳下頂禮膜拜。我怎么那么倒霉，每天被人踩來(lái)踩去，又臟又累，石頭和石頭怎么那么大差距呢?被雕成佛像的那塊石頭略一沉思，慢悠悠地說(shuō)：老兄，別忘了，進(jìn)這座廟時(shí)，你只挨了四刀，我可是挨過(guò)千刀萬(wàn)剮呀!
