V7.2ZK-751W73立式雙螺桿泵配YB250M-4/55KW防爆電機流量200m3/h,壓力0.6Mpa輸送柴油泵安裝尺寸圖.該泵進口口徑200,出口口徑200
外觀形式不同,立式泵是立著的而臥式泵是橫臥著. Different form appearance, vertical pump is standing and horizontal pump is lying.
連接形式不同,立式泵自下而上疊加連接,臥式泵縱向排列于底座上，立式泵通稱管道泵，電機與泵體是子口連接；臥式泵是采用聯(lián)軸器與電機連接，需要定期找正。 Superposition of different connection forms, the vertical pump bottom-up connection, horizontal pump vertically on the base, known as vertical pump pipeline pump, motor and pump body is seam allowance;Horizontal pump is connected by shaft coupling and motor, need to find is on a regular basis.
占地空間不同,立式泵占地面積小而臥式泵占用面積大.。立式泵組的占地比臥式泵小，不一定要打基礎(chǔ)；臥式泵組設(shè)有底座，要打基礎(chǔ)。 Covers an area of space is different, the vertical pump area small and horizontal pump takes up the area is large..Vertical pump group covers an area of smaller than horizontal pump, doesn't have to lay the foundation;Horizontal pump group has a base, to lay the foundation.
維修難度不同,立式泵檢修難度大,如檢修葉輪需將上部全部移去后方能進行;而臥式泵相對容易,如IS型泵只要將進口管移去就能進行葉輪檢修. Maintenance difficulty is different, vertical pump maintenance is difficult, such as repair impeller should be the upper can all move to the rear;Horizontal pump easier, such as IS as long as the move imported tube type pump impeller repair can go.
安裝形式不同,立式泵為整體連接,安裝較易;而臥式泵安裝后需進行精度調(diào)整. Different forms of installation, the vertical pump connection, for whole installation easier;But it's necessary for horizontal pump installed precision adjustment.
臥式泵從經(jīng)濟上來說比立式泵具有優(yōu)勢.Horizontal pump economically than the vertical pump.
雙螺桿泵有密封式和不密封式兩種類型，按介質(zhì)從一端還是 從兩端進入嚙合空間，雙螺桿又被分為雙吸式和單吸式兩種結(jié)構(gòu)。雙螺桿泵是外嚙合的螺桿泵，它利用相互嚙合，互不接觸的兩根螺桿來抽送液體。雙螺桿泵為一種雙吸式非密閉的雙螺桿泵。一端伸出泵外的主動螺桿由原動機驅(qū)動。主動螺桿與從動螺桿具有不同旋向的螺紋。螺桿與泵體緊密貼合。從動螺桿是通過同步齒輪由主動螺桿帶動的。
