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(wú)關(guān),且與輸送介質(zhì)的溫度、粘度等物理、化學(xué)性質(zhì)無(wú)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(wú)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(lái)說,在啟動(dòng)前通常不需灌泵。 機(jī)器效率高,節(jié)能。 6.高壓柱塞泵的流量 泵的理論流量:Qt=AsnZ
