東莞艾科工業(yè)自動化設(shè)備有限公司專業(yè)進口德國PARKER液壓泵，葉片泵，柱塞泵，齒輪泵，電磁閥，控制閥，等產(chǎn)品，一手貨源，廠價直銷，*，貨期短，自己報關(guān)，歡迎新老用戶前來詢價采購
PARKER齒輪泵現(xiàn)貨公司總銷售齒輪泵是依靠泵缸與嚙合齒輪間所形成的工作容積變化和移動來輸送液體或使之增壓的回轉(zhuǎn)泵。由兩個齒輪、泵體與前后蓋組成兩個封閉空間，當(dāng)齒輪轉(zhuǎn)動時，齒輪脫開側(cè)的空間的體積從小變大，形成真空，將液體吸入，齒輪嚙合側(cè)的空間的體積從大變小，而將液體擠入管路中去。吸入腔與排出腔是靠兩個齒輪的嚙合線來隔開的。齒輪泵的排出口的壓力*取決于泵出口處阻力的大小。
PARKER齒輪泵現(xiàn)貨公司總銷售齒輪泵工作時，主動輪隨電動機一起旋轉(zhuǎn)并帶動從動輪跟著旋轉(zhuǎn)。當(dāng)吸入室一側(cè)的嚙合齒逐漸分開時，吸入室容積增大，壓力降低，便將吸人管中的液體吸入泵內(nèi)；吸入液體分兩路在齒槽內(nèi)被齒輪推送到排出室。液體進入排出室后，由于兩個齒輪的輪齒不斷嚙合，使液體受擠壓而從排出室進入排出管中。主動齒輪和從動齒輪不停地旋轉(zhuǎn)，泵就能連續(xù)不斷地吸入和排出液體。
齒輪泵除具有自吸能力、流量與排出壓力無關(guān)等特點外，泵殼上無吸入閥和排出閥，具有結(jié)構(gòu)簡單，流量均勻、工作可靠等特性，但效率低、噪音和振動大、易磨損，主要用來輸送無腐蝕性、無固體顆粒并且具有潤滑能力的各種油類，溫度一般不超過70 ℃，例如潤滑油、食用植物油等。一般流量范圍為0.045～30ms/h，壓力范圍為0.7—20MPa，工作轉(zhuǎn)速為1200—4000r/min。
