當(dāng)柱塞泵開始工作時(shí)，柱塞在泵軸的驅(qū)動(dòng)下開始往復(fù)運(yùn)動(dòng)。在柱塞向后運(yùn)動(dòng)的過程中，缸體內(nèi)的容積逐漸增大，

形成了一定的負(fù)壓，這使得外界液體得以通過進(jìn)口單向閥被吸入缸體。而當(dāng)柱塞向前運(yùn)動(dòng)時(shí)，缸體內(nèi)的容積減小

，液體被壓縮，壓力逐漸升高。當(dāng)這個(gè)壓力超過出口單向閥的開啟壓力時(shí)，液體便被推出泵體，完成了整個(gè)泵送

過程。

這個(gè)過程看似簡單，卻蘊(yùn)含了豐富的機(jī)械原理和工程智慧。柱塞的往復(fù)運(yùn)動(dòng)，不僅實(shí)現(xiàn)了液體的連續(xù)泵送，而且

通過調(diào)節(jié)柱塞的運(yùn)動(dòng)速度和行程，還可以實(shí)現(xiàn)對(duì)泵送流量的精確控制。此外，柱塞泵還采用了多種密封措施，確

保在高壓環(huán)境下也能保持良好的密封性能，防止液體泄漏。
