在鐵路工程節能降耗的調查中發（fā）現，蓄水池二次供水係統采用的離心泵設備設置（zhì）有泵房及通風采暖附屬（shǔ）設施，離心（xīn）泵工作時，電動機風冷噪（zào）音大，水泵填料（liào）需要日常維護，存在占地麵積大、能耗高、工（gōng）作條件惡（è）劣以及供水設施建設與運營成（chéng）本指標高的突出問題。對於設置於管井（jǐng）水體（tǐ）中的潛水泵，無需風冷和（hé）通風采暖設施，能耗低，但在更換維護（hù）時，需要頻繁分解和安裝揚水管，維護十分麻煩；另外，由於節能高揚程潛水泵電（diàn）動（dòng）機設（shè）置在水泵組下部，導致潛水（shuǐ）泵進水口（kǒu）位置高，在淺水域蓄水池使用時易產生旋流進氣，影響（xiǎng）工作效率。
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供水裝置在允分利用（yòng）潛水泵供水設備的基礎上，通過潛水泵揚水管(套管（guǎn）)結合了潛水泵碟合器和“穿裙子（zǐ）”導流兩種（zhǒng）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（qì），是根據“錐度四凸形（xíng）環盤（pán）”自動（dòng）碟合原理，使潛水泵與揚水管（guǎn）非固定連接。即把錐度（dù）凸形環盤倒置在潛水泵出水口上，潛水（shuǐ）泵依靠自重自動滑入揚水管(套管)上設置的錐度四環形盤中心進行（háng）碟合，從而實現非固定連（lián）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“穿裙子”導流的技術，是在不（bú）改變（biàn）潛水泵自身設計結構（gòu）的基礎上，在潛（qián）水泵出水口（kǒu）以（yǐ）下部分為潛水泵環形出水口（kǒu）設置（zhì）進水（shuǐ）導流（liú）管，使進水水（shuǐ）流由潛水泵底部流入，滿（mǎn）足降低潛水泵的進水口位置高的安裝要求。
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.
