在鐵路工程節能降耗的調查（chá）中發現，蓄水池二次供水係統采（cǎi）用的離心泵設備（bèi）設置有泵（bèng）房及通（tōng）風采暖（nuǎn）附屬設施，離心泵工作時，電動機風冷（lěng）噪音大，水（shuǐ）泵填料（liào）需要日常維護（hù），存（cún）在占地麵積大、能耗高、工作條（tiáo）件惡劣以及供水設施建設與運營成本指標高的突（tū）出問題。對於設置於管井水體中的（de）潛水泵，無需風冷和通風采暖（nuǎn）設施，能耗低，但在（zài）更換維護時（shí），需要頻繁分解和安裝揚水管（guǎn），維護十分麻煩；另外（wài），由（yóu）於節能高（gāo）揚程潛水泵電動機設（shè）置在水泵組下部，導致（zhì）潛水泵進水口位置高，在淺水域蓄（xù）水池使用時易產（chǎn）生旋流進氣，影響工作效（xiào）率。
In the investigation of energy saving and consumption reduction in railway engineering, it is found that centrifugal pump equipments used in secondary water supply system of water storage pool are equipped with pump house and auxiliary facilities of ventilation and heating. When centrifugal pump works, the noise of motor air cooling is high, the filling of pump needs daily maintenance, and there are large occupied area, high energy consumption, poor working conditions and water supply facilities. The prominent problem of high construction and operation cost index. For submersible pumps installed in the water body of pipe wells, there is no need for air cooling and ventilation heating facilities, and the energy consumption is low, but when replacing and maintaining, it is very troublesome to decompose and install the riser frequently. In addition, because the motor of the energy-saving high-lift submersible pump is set at the lower part of the pump group, the position of the submersible pump intake is high and it is in shallow water. Swirling intake is easy to occur when the reservoir is used, which affects the working efficiency.
潛水泵自動碟合管道（dào）供水裝置在允分利用潛水泵供水設備的基礎上，通過潛水泵揚（yáng）水管(套管)結合了潛水泵碟合器和“穿裙子”導流兩種技術。
Based on the allowable use of submersible pump water supply equipment, submersible pump disc closure and skirt-piercing diversion technology are combined through submersible pump riser (casing) in the submersible pump automatic disc closure pipeline water supply device.
潛水泵碟合器，是根據“錐度四凸形環盤”自動碟合原理，使潛水泵與揚水管非固定連接。即把錐度凸形（xíng）環盤倒置在潛（qián）水泵出水口上，潛水泵依（yī）靠自重自動滑入揚水（shuǐ）管(套（tào）管)上設置的錐度四環形盤中心進行碟合，從而實現非固定連接。
Submersible pump disc closer is based on the principle of automatic disc closure of "conical four convex ring disc", which makes the submersible pump and the riser non-fixed connection. That is to say, the tapered convex ring disc is inverted on the outlet of the submersible pump, and the submersible pump automatically slides into the center of the tapered four-ring disc set on the riser (casing) by self-weight to realize the non-fixed connection.
潛水泵“穿（chuān）裙子”導流的技術，是在不改變潛水泵自（zì）身設計結構的基礎上，在潛（qián）水泵（bèng）出（chū）水口（kǒu）以下部分為潛水泵（bèng）環形出水口設置進水導流管，使進水水流由潛水泵底部流入，滿（mǎn）足降低潛水泵的（de）進水口位置（zhì）高的安裝要求。
The "skirt-wearing" diversion technology of submersible pump is to set up intake diversion pipes for the annular outlet of submersible pump below the outlet of submersible pump without changing the design structure of submersible pump itself, so that the intake water flows from the bottom of submersible pump to meet the installation requirements of reducing the high position of the intake of submersible pump.
