在铁路工程节能降耗的调查中发现，蓄水池二次供水系统采用的离心泵设备设置有泵房及通风采暖附属设施，离心泵工作时，电动机风冷噪音大，水泵填料需要日常维护，存在占地面积大、能耗高、工作条件恶劣以及供水设施建设与运营成本指标高的突出问题。对于设置于管井水体中的潜水泵，无需风冷和通风采暖设施，能耗低，但在更换维护时，需要频繁分解和安装扬水管，维护十分麻烦；另外，由于节能高扬程潜水泵电动机设置在水泵组下部，导致潜水泵进水口位置高，在浅水域蓄水池使用时易产生旋流进气，影响工作效率。

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.

      潜水泵自动碟合管道供水装置在允分利用潜水泵供水设备的基础上，通过潜水泵扬水管(套管)结合了潜水泵碟合器和“穿裙子”导流两种技术。

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.

       潜水泵碟合器，是根据“锥度四凸形环盘”自动碟合原理，使潜水泵与扬水管非固定连接。即把锥度凸形环盘倒置在潜水泵出水口上，潜水泵依靠自重自动滑入扬水管(套管)上设置的锥度四环形盘中心进行碟合，从而实现非固定连接。

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.

        潜水泵“穿裙子”导流的技术，是在不改变潜水泵自身设计结构的基础上，在潜水泵出水口以下部分为潜水泵环形出水口设置进水导流管，使进水水流由潜水泵底部流入，满足降低潜水泵的进水口位置高的安装要求。

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.
