Description
Technical field:
The utility model relates to a kind of vapour front pump and deaerator storage tank circulating pipe system, is applied to power plant's generating equipment.
Background technology:
Along with the propelling of power plant's energy conservation, generation current unit starting way of supplying water is supplied water generally to change into by the heat pump group by electric pump and supplies water.Because few to water demand in the generating set initial start stage, cause the vapour front pump under the lower situation of flow, to move, often need move 3-5 hour being lower than the minimum flow of requirement under.The long-time running under low discharge of vapour front pump is not allowed to, and can cause defectives such as axial float is big, the leakage of oil of oil shelves.
The utility model content:
The purpose of the utility model is in order to overcome an above-mentioned difficult problem a kind of vapour front pump and deaerator storage tank circulating pipe system to be provided.
The utility model is implemented by following technical scheme: vapour front pump and deaerator storage tank circulating pipe system; It comprises vapour front pump, vapour front pump water inlet pipe, the preceding water pump outlet pipe of vapour, deaerator storage tank, deoxygenation recirculation pump, deoxygenation recirculation pump water inlet pipe and deoxygenation recirculation pump return pipe; Wherein, Said vapour front pump water inlet pipe one end is communicated with said deaerator storage tank, and the said vapour front pump water inlet pipe other end is communicated with the water inlet of said vapour front pump; On the delivery port of said vapour front pump, be provided with water pump outlet pipe before the said vapour; Said deoxygenation recirculation pump water inlet pipe one end is communicated with said deaerator storage tank, and the said deoxygenation recirculation pump water inlet pipe other end is communicated with the water inlet of said deoxygenation recirculation pump; Said deoxygenation recirculation pump return pipe one end is communicated with said deaerator storage tank, and the said deoxygenation recirculation pump return pipe other end is communicated with the delivery port of said deoxygenation recirculation pump; It also comprises the preceding pump discharge circulation pipe of vapour, and pump discharge circulation pipe one end is communicated with the preceding water pump outlet pipe of said vapour before the said vapour, and the pump discharge circulation pipe other end is communicated with said deoxygenation recirculation pump return pipe before the said vapour; Before said vapour, be provided with two isolating valves on the pump discharge circulation pipe, before the said vapour between two said isolating valves before the said vapour in pump discharge circulation pipe upper edge water pump outlet pipe be provided with control valve and non-return valve successively to said deoxygenation recirculation pump return pipe direction.
The advantage of the utility model: solved and to have satisfied the technical barrier that the preceding water supplying pump of energy-conservation needs use vapour does not damage equipment again, made the economy of unit and the security of equipment all be improved.
Description of drawings:
Fig. 1 is the connection sketch map of the utility model.
Water pump outlet pipe 3, deaerator storage tank 4, deoxygenation recirculation pump 5, deoxygenation recirculation pump water inlet pipe 6, deoxygenation recirculation pump return pipe 7, control valve 9, non-return valve 10 before vapour front pump 1, vapour front pump water inlet pipe 2, the vapour.
The specific embodiment: as shown in Figure 1; Vapour front pump and deaerator storage tank circulating pipe system; It comprises vapour front pump 1, vapour front pump water inlet pipe 2, the preceding water pump outlet pipe 3 of vapour, deaerator storage tank 4, deoxygenation recirculation pump 5, deoxygenation recirculation pump water inlet pipe 6 and deoxygenation recirculation pump return pipe 7; Wherein, vapour front pump water inlet pipe 2 one ends are communicated with 4 with deaerator storage tank, and vapour front pump water inlet pipe 2 other ends are communicated with the water inlet of vapour front pump 1; Water pump outlet pipe 3 before on the delivery port of vapour front pump 1, being provided with vapour; Deoxygenation recirculation pump water inlet pipe 6 one ends are communicated with deaerator storage tank 4, and deoxygenation recirculation pump water inlet pipe 6 other ends are communicated with the water inlet of deoxygenation recirculation pump 5; Deoxygenation recirculation pump return pipe 7 one ends are communicated with deaerator storage tank 4, and deoxygenation recirculation pump return pipe 7 other ends are communicated with the delivery port of deoxygenation recirculation pump 5; It also comprises the preceding pump discharge circulation pipe 8 of vapour, and pump discharge circulation pipe 8 one ends are communicated with the preceding water pump outlet pipe 3 of vapour before the vapour, and pump discharge circulation pipe 8 other ends are communicated with deoxygenation recirculation pump return pipe 7 before the vapour; Before vapour, be provided with control valve 9 and non-return valve 10 on the pump discharge circulation pipe 8; Before vapour, be provided with two isolating valves 11 on the pump discharge circulation pipe 8, before the vapour between two isolating valves 11 before the pump discharge circulation pipe 8 upper edge vapour water pump outlet pipe 3 be provided with control valve 9 and non-return valve 10 successively to deoxygenation recirculation pump return pipe 7 directions; Open two isolating valves 11 during unit starting, and through the suitable flow of control valve 9 control vapour front pump 1; Channelling when non-return valve 10 normally moves with the delivery port of the delivery port that prevents deoxygenation recirculation pump 5 and vapour front pump 1.
Explanation of nouns:
The vapour front pump: i.e. steam feed pump fore pump, be called for short the vapour front pump.Be installed on the steam feed pump inlet, be used to promote the steam feed pump inlet pressure, close with steam feed pump and claim the steam feed pump group.
The deoxygenation recirculation pump: when starting oxygen-eliminating device, the ON cycle recirculation pump makes deoxygenation head and water tank self circulation, and water in the heating deaerator storage tank rises temperature very soon, and unit starting speed is improved.
Axle is scurried: water pump is in operation, and rotor swinging back and forth vertically is called axle and scurries.Axle was scurried senior general and was damaged bearing and pump part, threatened the safe operation of water pump.
