Abstract
The utility model relates to a water-feeding pump circulative cooling system, its characterized in that: branch pipe (A1) and branch pipe (A2) are connected in delivery pipe (A) of desalinized water supply station (1), and branch pipe (A1) and branch pipe (A2) correspond the water inlet of connecting bearing seal (5) at multistage feed-water pump (9) both ends respectively, and wet return (B) is connected to the delivery port of bearing seal (5), and wet return (B) inserts return collecting vat (8). The influence of metal ions such as Ca2+, mg + and the like in the circulating water on the hardness of the boiler water is solved, and the scale formation in the water-cooled wall is avoided. The accidents caused by the steam-water pipeline breakage of the boiler are reduced every year, and the mass production outage cost and the direct maintenance cost are reduced.
Description
Technical Field
The utility model belongs to the water pump field, concretely relates to water-feeding pump circulative cooling system.
Background
In the prior art, circulating water is used for cooling and lubricating a water-feeding pump shaft seal, the circulating water contains a large amount of Ca < 2+ >, mg < + > and Fe < 3+ > ions, the hardness value of the circulating water is very high, the national standard requires that the hardness in boiler water, namely the content of the Ca < 2+ >, mg < + > and Fe < 3+ > ions, is low to an unmeasured degree, so that if the water-feeding pump shaft seal leaks, a large amount of scale formation of a boiler water-cooling system can be caused in a short period, wherein the main scale components comprise: caCO3, caSO4 and ferrous salt have influence on equipment, and the influence is specifically represented by the problems of poor heat absorption capacity, low load, tube explosion of pipelines, high consumption speed of phosphate ions in operation and the like of a boiler water cooling system. In the prior art, a multistage water feed pump and a circulating cooling water cool the internal mechanical seal and the bearing bush part to easily leak, so that circulating water is frequently mixed with desalted water, the water quality of a boiler is deteriorated, and the boiler is exploded.
Disclosure of Invention
The utility model aims at avoiding the defects of the prior art and providing a water feeding pump circulating cooling system.
In order to realize the purpose, the invention adopts the technical scheme that: a feed pump circulative cooling system which characterized in that: two branch pipes of delivery pipe connection of desalinized water supply station, two branch pipes correspond the water inlet of the bearing seal of connecting multistage feed pump both ends respectively, and the wet return is connected to the delivery port of bearing seal, and the wet return inserts the return collecting vat.
And the water supply pipe and the water return pipe are respectively provided with a control valve, a pressure gauge and a thermometer.
And the water return pipe is also provided with a flow regulating valve.
The utility model has the advantages that: the influence of metal ions such as Ca2+, mg + and the like in the circulating water on the hardness of boiler water is solved, and the scale formation in the water-cooled wall is avoided. The accidents caused by the steam-water pipeline breakage of the boiler are reduced every year, and the mass production outage cost and the direct maintenance cost are reduced.
Drawings
FIG. 1 is a schematic view of the present invention;
in the figure: the method comprises the following steps of 1-desalted water supply station, 2-control valve, 3-pressure gauge, 4-thermometer, 5-shaft seal, 6-bearing cover, 7-flow regulating valve, 8-backwater collecting tank, 9-multi-stage water supply pump and 10-leakage point.
Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
Embodiment 1, see fig. 1, a feed pump hydronic system, characterized in that: the delivery pipe A of desalinized water supply station 1 connects branch pipe A1 and branch pipe A2, and branch pipe A1 and branch pipe A2 correspond the water inlet of the bearing seal 5 of connecting multistage feed pump 9 both ends respectively, and wet return B is connected to the delivery port of bearing seal 5, and wet return B inserts return collecting vat 8.
And the water supply pipe A and the water return pipe B are respectively provided with a control valve 2, a pressure gauge 3 and a thermometer 4.
And the water return pipe B is also provided with a flow regulating valve 7.
The working process is as follows:
the desalted water is sent out by desalted water supply station 1 through water supply pipe A, gets into from bearing seal 5 of multistage feed pump 9 and cools it, reentries the clearance between axle and the bearing cap 6 and is leakage point 10, prevents to leak as sealed water, then gets into return water collecting vat 8 through wet return B.
The pressure gauge 3 and the dial thermometer 4 with switches, which are additionally arranged on the water supply pipe A and the water return pipe B, are used for observing the pressure and the temperature of the desalted water in the water supply pipe A, and the inlet temperature of the desalted water is ensured not to exceed 17 ℃.
The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification made within the spirit of the present invention is equivalent to replacement, improvement, etc., and all should be included within the protection scope of the present invention.
