上海供應(yīng)美國(guó)威格士VICKERS柱塞泵
理論上，泵的流量只取決于泵的主要結(jié)構(gòu)參數(shù) n（每分鐘往復(fù)次數(shù)）、S（活塞行程）、D（活塞直徑）、Z（活塞數(shù)目），與排出壓力無關(guān)，且與輸送介質(zhì)的溫度、粘度等物理、化學(xué)性質(zhì)無關(guān)。所以說泵的流量是恒定的。
3.泵的壓力取決于管道特性
柱塞泵的排出壓力不能由泵本身限定，而是取決于泵裝置的管道特性，并且與流量無關(guān)。也就是說，如果認(rèn)為輸送液體是不可壓縮的，那么，在理論上可認(rèn)為往復(fù)泵的排出壓力將不受任何限制，即可根據(jù)泵裝置的管道特性，建立泵的任何所需的排出壓力。當(dāng)然，所有往復(fù)泵都有一個(gè)泵的排出壓力的規(guī)定，這不是說該泵的排出壓力不會(huì)再升高，而只是說，由于原動(dòng)機(jī)額定功率和泵本身的結(jié)構(gòu)強(qiáng)度的限制，不允許在超出這一排出壓力下使用而己。
4.對(duì)輸送介質(zhì)有較強(qiáng)的適應(yīng)性
柱塞泵原則上可以輸送任何介質(zhì)，幾乎不受介質(zhì)的物理性能和化學(xué)性能的限制。當(dāng)然，由于液力端的材料和制造工藝以及密封技術(shù)的限制，有時(shí)也會(huì)遇到不能適應(yīng)的情況。
5.有良好的自吸性能
柱塞泵不僅有良好的吸入性能，而且還有良好的自吸性能。因此，對(duì)多數(shù)往復(fù)泵來說，在啟動(dòng)前通常不需灌泵。 機(jī)器效率高，節(jié)能。
