PARKER柱塞泵對輸送介質(zhì)有較強的適應(yīng)性；
PARKER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，有時也會遇到不能適應(yīng)的情況。
泉州市天益機電貿(mào)易有限公司 www.qztyjd.com 0595-68253668 蔣女士 企業(yè)QQ 3001030018 原裝進(jìn)口，價格貨期絕對優(yōu)勢，歡迎各界朋友來詢合作！PARKER柱塞泵平均流量是恒定的
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。PARKER柱塞泵是依靠工作元件在泵缸內(nèi)作往復(fù)或回轉(zhuǎn)運動，使工作容積交替地增大和縮小，以實現(xiàn)液體的吸入和排出。工作元件作往復(fù)運動的容積式泵稱為往復(fù)泵，作回轉(zhuǎn)運動的稱為回轉(zhuǎn)泵。前者的吸入和排出過程在同一泵缸內(nèi)交替進(jìn)行，并由吸入閥和排出閥加以控制；后者則是通過齒輪、螺桿、葉形轉(zhuǎn)子或滑片等工作元件的旋轉(zhuǎn)作用，迫使液體從吸入側(cè)轉(zhuǎn)移到排出側(cè)。
PARKER柱塞泵在一定轉(zhuǎn)速或往復(fù)次數(shù)下的流量是一定的，幾乎不隨壓力而改變；往復(fù)泵的流量和壓力有較大脈動，需要采取相應(yīng)的消減脈動措施；回轉(zhuǎn)泵一般無脈動或只有小的脈動；具有自吸能力，泵啟動后即能抽除管路中的空氣吸入液體；啟動泵時必須將排出管路閥門完全打開；往復(fù)泵適用于高壓力和小流量；回轉(zhuǎn)泵適用于中小流量和較高壓力；往復(fù)泵適宜輸送清潔的液體或氣液混合物?？偟膩碚f，容積泵的效率高于動力式泵。
PARKER柱塞泵動力式泵靠快速旋轉(zhuǎn)的葉輪對液體的作用力，將機械能傳遞給液體，使其動能和壓力能增加，然后再通過泵缸，將大部分動能轉(zhuǎn)換為壓力能而實現(xiàn)輸送。動力式泵又稱葉輪式泵或葉片式泵。離心泵是zui常見的動力式泵。
PARKER柱塞泵在一定轉(zhuǎn)速下產(chǎn)生的揚程有一限定值，揚程隨流量而改變；工作穩(wěn)定，輸送連續(xù)，流量和壓力無脈動；一般無自吸能力，需要將泵先灌滿液體或?qū)⒐苈烦槌烧婵蘸蟛拍荛_始工作；適用性能范圍廣；適宜輸送粘度很小的清潔液體，特殊設(shè)計的泵可輸送泥漿、污水等或水輸固體物。動力式泵主要用于給水、排水、灌溉、流程液體輸送、電站蓄能、液壓傳動和船舶噴射推進(jìn)等。

PARKER柱塞泵的主要特點是：①一定的泵在一定轉(zhuǎn)速下所產(chǎn)生的揚程有一限定值。工作點流量和軸功率取決于與泵連接的裝置系統(tǒng)的情況(位差、壓力差和管路損失)。揚程隨流量而改變(圖2)。②工作穩(wěn)定，輸送連續(xù),流量和壓力無脈動。③一般無自吸能力,需要將泵先灌滿液體或?qū)⒐苈烦槌烧婵蘸蟛拍荛_始工作。④離心泵在排出管路閥門關(guān)閉狀態(tài)下啟動，旋渦泵和軸流泵在閥門全開狀態(tài)下啟動，以減少啟動功率。⑤離心泵適合于用高速電動機和汽輪機等直接驅(qū)動,結(jié)構(gòu)簡單,制造成本低，維修方便。⑥適用性能范圍廣，離心泵的流量可以從幾到幾十萬米3/時，揚程可以從數(shù)米到數(shù)千米；軸流泵一般適用于大流量和低揚程(20米以下)。離心泵和軸流泵的效率一般在80％以下，高的可達(dá)90％。PARKER柱塞泵的性能曲線泵的各個性能參數(shù)之間存在著一定的相互依賴變化關(guān)系，可以通過對泵進(jìn)行試驗，分別測得和算出參數(shù)值，并畫成曲線來表示，這些曲線稱為泵的特性曲線。每一臺泵都有特定的特性曲線，由泵制造廠提供。通常在工廠給出的特性曲線上還標(biāo)明推薦使用的性能區(qū)段，稱為該泵的工作范圍。
PARKER柱塞泵的實際工作點由泵的曲線與泵的裝置特性曲線的交點來確定。選擇和使用泵，應(yīng)使泵的工作點落在工作范圍內(nèi)，以保證運轉(zhuǎn)經(jīng)濟(jì)性和安全。此外，同一臺泵輸送粘度不同的液體時，其特性曲線也會改變。通常，泵制造廠所給的特性曲線大多是指輸送清潔冷水時的特性曲線。對于動力式泵，隨著液體粘度增大，揚程和效率降低，軸功率增大，所以工業(yè)上有時將粘度大的液體加熱使粘性變小，以提高輸送效率。
泉州市天益機電貿(mào)易有限公司 www.qztyjd.com 0595-68253668 蔣女士 企業(yè)QQ 3001030018 原裝進(jìn)口，價格貨期絕對優(yōu)勢，歡迎各界朋友來詢合作！PARKER柱塞泵的壓力取決于管道特性:PARKER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)泵都有一個泵的排出壓力的規(guī)定，這不是說該泵的排出壓力不會再升高，而只是說，由于原動機額定功率和泵本身的結(jié)構(gòu)強度的限制，不允許在超出這一排出壓力下使用而己。
