Abstract
A sealing water supplying system of a feed pump comprises a main condensate water pipe, wherein the main condensate water pipe is provided with two branch pipes, each branch pipe is sequentially provided with a left valve, a filter and a right valve, and the two branch pipes are converged to form a water supply outlet. The sealing water supplying system is characterized in that a main desalted water pipe is connected to the main condensate water pipe, a valve is arranged on the main desalted water pipe, a branch desalted water pipe is connected to the outer sides of the left valves and the outer sides of the right valves, and two valves are arranged on the branch desalted water pipe. Due to the fact that the main desalted water pipe and the branch desalted water pipe are arranged, desalted water can be directly supplied in the initial state of water supply. When the rotating speed of a turbine rises, the iron content in a water condensation device naturally declines, then, the water condensation device is used for water supplying, energy is greatly saved, production efficiency is improved, and the quality of supplied water is qualified. Due to the fact that the plurality of valves are arranged and the branch desalted water pipe is connected to the outer sides of the left valves and the outer sides of the right valves, the water supply sources can be conveniently switched by opening and closing the valves.
Description
Technical field
The utility model relates to a kind of generating auxiliary equipment, special standby a kind of Sealing Water for Feedwater Pump supply system that relates to.
Background technique
In power generating equipment, vapour front pump, electric front pump need to be realized sealing by sealing water.Existing Sealing Water for Feedwater Pump supply system be used to sealing water is provided has a solidifying jellyfish pipe, and described solidifying jellyfish pipe is provided with two branch roads, is connected with respectively left valve, filter, right valve on two branch roads in turn, and two branch roads converge formation for water out.During use, the port of solidifying jellyfish pipe is connected with the female pipe of the pump discharge that condenses, will be connected with the sealing water inlet for the treatment of water supply installation (electric front pump, vapour front pump, air pump etc.) for water out.
The shortcoming of this structure is: when condenser started, turbine speed was not high, and the iron-holder in its oxygen-eliminating device is higher, causes condenser water supply iron-holder higher, and the condenser initial stage supplies water and do not conform with the requirement that seals water.Need to be to a large amount of demineralized waters of supplying with in oxygen-eliminating device to guarantee the condenser water supply quality.Every machine consumes more than demineralized water 500t, medicine 0.5t, power consumption reaches 7000 degree at every turn, not only wastes energy, and greatly reduces manufacturing efficiency.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple to operate, and feedwater efficiency is high, energy saving, the Sealing Water for Feedwater Pump supply system that feedwater quality is qualified.
The utility model is achieved in that
A kind of Sealing Water for Feedwater Pump supply system, a solidifying jellyfish pipe is arranged, described solidifying jellyfish pipe is provided with two branch roads, be connected with respectively left valve, filter, right valve in turn on two branch roads, two branch roads converge formation for water out, and its special way is: be connected with desalination jellyfish pipe on solidifying jellyfish pipe, be provided with a valve on desalination jellyfish pipe, be connected with the demineralized water branch road in left valve, the right valve outside, separately be provided with two valves on the demineralized water branch road.
The beneficial effects of the utility model are:
1,, owing to being provided with desalination jellyfish pipe, demineralized water branch road, can directly use demineralized water to supply water at the water supply initial stage.After turbine speed rose, in condenser, iron content descended naturally, then by condenser, supplies water, and has greatly saved energy, improved manufacturing efficiency, and water supply quality is qualified.
,Owing to being provided with a plurality of valves, and the demineralized water branch road is positioned at left valve, the right valve outside, so, can supply water and originate by the switching of open and close valve easily.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: solidifying jellyfish pipe 1, desalination jellyfish pipe 2, valve 3, left valve 4, filter 5, right valve 6, demineralized water branch road 7, for water out 8.
Embodiment
As shown in the figure, this Sealing Water for Feedwater Pump supply system has a solidifying jellyfish pipe 1, and described solidifying jellyfish pipe 1 is provided with two branch roads, is connected with respectively left valve 4, filter 5, right valve 6 on two branch roads in turn.Two branch roads converge formation for water out 8, are connected with desalination jellyfish pipe 2 on solidifying jellyfish pipe 1, are provided with a valve 3 on desalination jellyfish pipe 2, in left valve 4, right valve 6 outsides, are connected with demineralized water branch road 7, separately are provided with two valves 3 on demineralized water branch road 7.
During connection, the port of solidifying jellyfish pipe 1 is connected with the female pipe of the pump discharge that condenses, desalination jellyfish pipe 2 will be connected with the sealing water inlet for the treatment of water supply installation (electric front pump, vapour front pump, air pump etc.) for water out 8 with the desalination water pump.
During use, left valve 4, right valve 6 are closed, all the other valves 3 are opened, supply with demineralized water, when turbine speed is promoted to 3000r/min, open left valve 4, right valve 6,, with all the other valve closings, by condenser, supply water.
