根據(jù)帕斯卡定律，在水力系統(tǒng)中的一個(gè)活塞上施加一定的壓強(qiáng)，必將在另一個(gè)活塞上產(chǎn)生相同的壓強(qiáng)增量。如果第二個(gè)活塞的面積是個(gè)活塞的面積的10倍，那么作用于第二個(gè)活塞上的力將增大為個(gè)活塞的10倍，而兩個(gè)活塞上的壓強(qiáng)仍然相等。這一定律是法國(guó)數(shù)學(xué)家、物理學(xué)家、哲學(xué)家布萊士·帕斯卡首先提出的。這個(gè)定律在生產(chǎn)技術(shù)中有很重要的應(yīng)用，液壓機(jī)就是帕斯卡原理的實(shí)例。它具有多種用途，如液壓制動(dòng)等。帕斯卡還發(fā)現(xiàn)靜止流體中任一點(diǎn)的壓強(qiáng)各向相等，即該點(diǎn)在通過(guò)它的所有平面上的壓強(qiáng)都相等。這一事實(shí)也稱(chēng)作帕斯卡原理。

CYCWC系列千斤頂分為機(jī)械千斤頂和液壓千斤頂兩種，原理各有不同。從原理上來(lái)說(shuō)，液壓千斤頂所基于的原理為帕斯卡原理，即：液體各處的壓強(qiáng)是一致的，這樣，在平衡的系統(tǒng)中，比較小的活塞上面施加的壓力比較小，而大的活塞上施加的壓力也比較大，這樣能夠保持液體的靜止。所以通過(guò)液體的傳遞，可以得到不同端上的不同的壓力，這樣就可以達(dá)到一個(gè)變換的目的。我們所常見(jiàn)到的液壓千斤頂就是利用了這個(gè)原理來(lái)達(dá)到力的傳遞。機(jī)械千斤頂采用機(jī)械原理，以往復(fù)扳動(dòng)手柄，拔爪即推動(dòng)棘輪間隙回轉(zhuǎn)，小傘齒輪帶動(dòng)大傘齒輪、使舉重螺桿旋轉(zhuǎn)，從而使升降套筒獲得起升或下降，而達(dá)到起重拉力的功能。但不如液壓千斤頂簡(jiǎn)易。福橋機(jī)械設(shè)備，廠家直銷(xiāo)全國(guó)各地。珠海千斤頂廠家哪家好</p><p
