[0005] The indirect air cooling circulating water pump house provided by the utility model can save investment and is convenient for operation personnel to overhaul and inspect, and has many advantages. CONTENT OF UTILITY MODEL

[0006] The utility model aims at solving the problems of high cost, inconvenient overhaul and inspection of conventional indirect air cooling system circulating water pump house, and provides a kind of indirect air cooling circulating water pump house, which is low in cost and convenient for operation personnel to overhaul and inspect.

[0007] To realize the above-mentioned utility model purpose, the utility model provides a kind of indirect air cooling circulating water pump house, circulating water pump is arranged in high position, multiple circulating water pumps and motors are arranged in circulating water pump house, and overhaul site is set in the end of circulating water pump house;Variable-diameter pipe, pipe joint and electric butterfly valve are set on circulating water pipe of circulating water pump water inlet;Variable-diameter pipe, pipe joint and hydraulic control butterfly valve are set on circulating water pipe of circulating water pump water outlet;Circulating water pump, motor, circulating water pump water inlet and water outlet circulating water pipe and valve and accessory thereon are arranged in pipe trench;Detachable steel cover plate is set on the top of pipe trench, the top elevation of steel cover plate is 0m, and the lower part of circulating water pump and motor is in pipe trench, and the upper part is above 0m layer.

[0008] Further, the multiple circulating water pumps and motors are arranged in single row, and the spaces on both sides of the circulating water pumps and motors are used as hoisting channels.

[0009] Compared with the conventional circulating water pump house, the utility model has the following beneficial effects:

[0010] (1) When the underground part is constructed, only the circulating water pump inlet and outlet pipeline part, the circulating water pump and motor underground part space need to be excavated, the excavation area is reduced by half compared with the conventional one, and the excavation depth is also reduced by half compared with the conventional pump house depth, so that the utility model can greatly reduce the excavation amount, and compared with the conventional 2x600MW level air cooling unit circulating water pump house, the excavation amount is reduced by nearly 3 / 4, about 2700m3.

[0011] (2) The circulating water pumps and motors are arranged in single row, and the circulating water pumps and motors on both sides can be used as hoisting channels, so that the hoisting parts do not need to cross the top of the circulating water pumps and motors, compared with the conventional circulating water pump house, the pump house ground part height does not need to be additionally increased, and the engineering quantity is not additionally increased.

[0012] (3) The 0m layer of the utility model is a large flat layer, the main part of the protruding part is the part of the circulating water pump and motor protruding 0m layer cover plate, the vision is broad, and the maintenance crawling ladder and the inspection ladder leading to the underground do not need to be arranged, so that the operation personnel can conveniently maintain and inspect.

[0013] (4) The 0m layer is a large flat layer, convenient for passing, and the span of the circulating water pump house can be further reduced under the condition of meeting the equipment hoisting space, and the circulating water pump house cost is further reduced. BRIEF DESCRIPTION OF DRAWINGS
