揚程：50~650m Head:50~650m
■ 型號說明 Explanation of Model
■ 結(jié)構(gòu)說明 Explanation of structure
●本系列泵為兩端支承，殼體部份是節(jié)段式，泵的傳動方式是通過彈性聯(lián)軸器與電機聯(lián)結(jié)。泵的旋轉(zhuǎn)方向，從驅(qū)動端看，為順時針方向旋轉(zhuǎn)。
This series pump is supported at both ends, and the shell part is ring segment, the pump is driven through flexible coupling and motor coupling. Looking from the back of the electrical machine, the pump’s rotation direction is clockwise.
● 定子部分 Stator
主要由吸入段、中段、吐出段、導葉、填料函體等組成，并用拉緊螺栓和螺母聯(lián)接成一體。吐出口均垂直向上，D型泵吸入口為水平方向，DG型泵為垂直向上。
Mainly consist of suction segment, connecting piece, discharge casing, guide vane, and stuffing body, etc. and link to one with tighten bolts and nuts. Outlet are all vertically upward, D-type pump’s inlet is horizontal, while DG-type pump’s inlet is vertically upward.
●轉(zhuǎn)子部分 Rotor
主要由軸、葉輪、平衡盤及軸套等零件組成。
Mainly consist of shaft, impeller, balancing disc, and shaft sleeve parts.
●泵的密封 Sealing
◆吸入段、中段、吐出段之間的靜止結(jié)合面用紙墊來密封。
Stationary joint surface such as suction segment, connecting piece and discharge casing is sealed with paper pad.
◆泵各級間采用節(jié)流密封。
Throttling seal is adopted between pump stage.
◆泵的兩側(cè)軸封采用軟填料密封。
Both sides of the pump shaft seals use soft packing seal.
◆采用擋水圈擋水，防止水進入軸承。
Retaining water by retaining ring, prevent water into the bearings.
●軸承部分 Bearing parts
整個轉(zhuǎn)子由軸兩端的圓柱滾子軸承來支承，軸承采用油脂潤滑。
The rotor is all supported by the cylindrical roller bearing on rotor sides, bearing is grease lubrication.
●平衡部分 Balancing Sets
由于葉輪前后蓋板受壓面積不等，要產(chǎn)生軸向力，此軸向力由平衡裝置承擔。
泵的平衡室由吐出段、填料函體，平衡水管(部件)所組成。其平衡水管(部件)不允許堵塞和用閘閥調(diào)水的流動。
As the unequal compression area of the impeller front and back cover, so produce axial force, this axial force is supported by balancing sets.
Pump balancing house consist of discharge casing, stuffing body, balancing water pipe( parts). The balance water pipe is absolutely not allowed to be blocked and make water flow with gate valve.
