技术领域technical field
本发明涉及设备更换技术领域，特别是涉及一种在线更换取水泵房取水设备的方法。The invention relates to the technical field of equipment replacement, in particular to a method for online replacement of water intake equipment in a pump house.
背景技术Background technique
取水泵房又名水源泵房、一级泵房。取水泵房用于从水源取水，将水送至净水构筑物，或直接将水送至用户的地表水取水泵房，通常和取水头部及进水间合建。由于水源水位变化较大，受水泵吸程的限制，而使泵房埋深较大，常建成半地下式或地下式结构，造价较高，为减少泵房面积，将水泵压水管上的阀门、多功能止回阀、流量计等多布置在泵房外专设的井内，且多采用立式水泵。The water intake pump room is also known as the water source pump room and the primary pump room. The water intake pump room is used to draw water from the water source, send the water to the water purification structure, or directly send the water to the user's surface water intake pump room, which is usually built together with the water intake head and the water intake room. Due to the large change in the water level of the water source and the limitation of the suction stroke of the pump, the pump house is buried deep, and it is often built into a semi-underground or underground structure, which is costly. , Multi-function check valve, flowmeter, etc. are mostly arranged in the specially designed well outside the pump room, and most of them use vertical water pumps.

然而，随着取水泵房内设备的老化，本单位现有取水泵组的供水能力逐年下降，能耗逐年增加，且水泵机组密封系统漏水严重，又因取水的水源来自江水，这些水源中泥沙含量较高，对水泵的冲涮及磨损均较严重。经过十多年的运行磨损，厂区现有泵站设备逐年老化，安全隐患层出不穷。机电设备严重老化、金属结构超期使用、自动化程度低、管理设施落后等诸多问题，严重影响泵站安全运行和正常效益发挥。取水泵房自取水泵以及各取水泵出水阀门等管件一直未曾改造，而随着发展需要，目前的提升泵组已经不能满足安全供水的需求，另外由于设备的老化，也给整个取水泵房控制系统的稳定运行带来了一定隐患。However, with the aging of the equipment in the water intake pump room, the water supply capacity of the existing water intake pump unit of the unit decreases year by year, the energy consumption increases year by year, and the sealing system of the water pump unit has serious water leakage. The sand content is high, and the flushing and wear of the water pump are serious. After more than ten years of operation and wear and tear, the existing pumping station equipment in the plant area is aging year by year, and safety hazards emerge one after another. Many problems, such as serious aging of mechanical and electrical equipment, overdue use of metal structures, low degree of automation, and backward management facilities, have seriously affected the safe operation of the pumping station and the normal performance of its benefits. Pipe fittings such as the self-intake pump and the outlet valves of each water-intake pump in the water-intake pump room have not been transformed. With the development needs, the current lifting pump group can no longer meet the needs of safe water supply. In addition, due to the aging of the equipment, the entire water-intake pump room is also controlled. The stable operation of the system brings certain hidden dangers.
