Abstract
The utility model discloses a machine set repairing drain system with the advantage of compact pipeline distribution, little excavation for building, flooding resistance and damp resistance of facility location, convenient mounting, repairing and operating, and the like. The machine set repairing drain system comprises a machine set, a machine set repairing drain pipe, a leakage water collecting well, an exhaust valve and an exhaust pipeline, a steel bushing exhaust pipe and a water turbine layer; the machine set comprises a tail water pipe disc-shaped valve; the tail water pipe disc-shaped valve of the machine set is connected with the leakage water collecting well via the machine set repairing drain pipe; the leakage water collecting well is connected with the water turbine layer via themachine set repairing drain pipe; two drain pumps of the leakage water collecting well are arranged on the water turbine layer; the two drain pumps are provided with manual valves and connected witha composite exhaust valve and a ball valve simultaneously; the two drain pumps are respectively connected with a lubricating water pipe and downstream tail water; and the lubricating water pipe and the downstream tail water are respectively provided with a pressure gauge and a valve.
Description
Technical field
The utility model relates to a kind of drainage for overhaul system, the unit maintenance drainage system that particularly relate to and a kind ofly be used for that the tail water back pressure is higher, the draining of factory building seepage and unit maintenance share the power station of collecting well.
Background technology
At present, should adopt the direct-type drainage pattern for underground power house or the higher hydroelectric power plant of tailwater level; For big-and-middle-sized hydroelectric power plant, unit maintenance drainage system and factory building seepage drainage system should divide and be arranged.
If adopt direct drainage pattern, what relatively use always on the engineering is to adopt centrifugal pump of horizontal axis directly to be connected draining with draft tube, but because the suction journey of centrifugal pump is limited, need be in the lower pump house or the hole of correct position excavation elevation of factory building, to satisfy the suction range request of water pump, the engineering excavation amount is big, construction investment increases, the difficulty of ventilating in the pump house, high humidity, the moisture resistant grade height of pump motor, equipment investment is big.Simultaneously, because pump house or hole elevation are lower, drainage pump is bigger by the danger of water logging, is unfavorable for draining after the accident of factory building.
Summary of the invention
The utility model aims to provide a kind of equipment line arrangement compactness, and factory building civil engineering excavated volume is less, apparatus arrangement possess anti-flood, advantage such as protection against the tide, and unit maintenance drainage system is easily installed, safeguarded, moves to equipment.
To achieve these goals, the technical solution of the utility model is as follows:
The utility model unit maintenance drainage system comprises unit, unit maintenance gutter, seepage collecting well, outlet valve gas exhaust piping, steel sleeve stack and turbine floor; Described unit has the draft tube disc valve, and the draft tube disc valve of described unit utilizes the unit maintenance gutter to connect the seepage collecting well; Described seepage collecting well utilizes the unit maintenance gutter to connect turbine floor; Two drainage pumps of described seepage collecting well are arranged in turbine floor, and described two drainage pumps have manually-operated gate, and connect composite exhaust valve and ball valve simultaneously; Described two drainage pumps connect lubricated water pipe and downstream tail water respectively, and lubricated water pipe and downstream tail water are respectively arranged with pressure meter and valve.
The beneficial effect of a kind of unit maintenance drainage system of the utility model is:
Described unit maintenance drainage system had both solved centrifugal pump of horizontal axis low bring unfavorable of elevation had been installed, and also having solved the common borehole shaft driven indirect drainage that utilizes needs the problem of a large amount of excavations.Maloperation causes the water logging factory building in the time of simultaneously avoiding unit maintenance, has improved safety factor, has promoted technological progress, has produced favorable economic benefit and social benefit.
