Description
Affiliated technical field
The utility model belongs to a kind of water supply installation, particularly a kind of voltage-stabilizing and energy-saving type water supply installation of hot-strip control cooling system.
Background technology
In recent years, the raising that steel strength, toughness and welding performance is required along with the continuous development of rolling technique and user, the controlled rolling and controlled cooling technology has been widely used in the actual steel rolling production process, because the control cooling system of traditional hot-strip adopts single high-level tank water device, therefore, have the following disadvantages:
The instantaneous water yield is greater than pump delivery, and the water level during water injection system work in the elevated tank descends, and the build-up of pressure fluctuation brings adverse effect for water injection system operating pressure and discharge uniformity;
The water supply capacity of the instantaneous water yield and pump is to need maximum steel grade and specification to design according to the water yield in the steel cooling, when producing the product of other steel grade and other specification, pump adopts continuous duty, cause the waste of the water yield, increased the weight of the burden of water treatment system, as wanting a large amount of waters or working continuously, will make troubles to work.
Summary of the invention
The water pressure fluctuations that exists at the single high-level tank water device of tradition is big, mass flow discrepancy and water yield waste, water treatment system deficiencies such as over-burden, the purpose of this utility model provides a kind of two high-level tank water devices of flow-controllable, and the lasting flow that hot-strip control cooling system is carried out pressure stability supplies water.
Technical solutions of the utility model are achieved in that its structure of this water supply installation is by upper water box, lower header, connecting pipeline and electromagnetic valve, water pipe and electromagnetic valve, main feed water pump, the overflow pond, water pump is returned in overflow, the water level meter, cistern, return flume, water treatment facilities, water return pipelines etc. are formed (as shown in Figure 1), its connection is to adopt the binary water tank, top is upper water box, the bottom is a lower header, between the last lower header by a plurality of connecting pipelines, on each pipeline electromagnetic valve is housed, a plurality of water pipes are housed below lower header, equally, on each pipeline electromagnetic valve is housed, return flume is housed below the water pipe, in the return flume side cistern is housed, between return flume and the cistern water treatment facilities are housed, connect with it by pipeline, pipeline connection main feed water pump vertically is housed in the cistern to be linked in the upper water box again, the lower header side is equipped with pipeline equally and is connected overflow and return water pump and lead in the upper water box, the water level meter all is housed in last lower header, wherein connecting pipeline is to be equipped with many groups of rapidly opened and closed electromagnetic valve to be connected with footpath or reducing pipeline between two water tanks, is an automatic closed-loop system during whole device operation.
The advantage of the utility model: have simple in structure, with low cost, voltage stabilizing, advantage such as energy-conservation.
Description of drawings
Fig. 1 is a hot-strip control cooling system voltage-stabilizing and energy-saving water supply installation structure principle chart.
Among the figure: 1 upper water box, 2 lower headers, 3 connecting pipelines and electromagnetic valve, 4 water pipes and electromagnetic valve, 5 main feed water pumps, 6 overflow ponds, water pump is returned in 7 overflows, 8,9 water level meters, 10 cisterns, 11 return flumes, 12 water treatment facilities, 13 water return pipelines, 14 band steel.
The specific embodiment
This apparatus structure and operation principle are described in detail in conjunction with the accompanying drawings.
Its structure as shown in Figure 1, main feed water pump 5 adopts discontinuous operation systems, water level meter 9 is equipped with in the upper water box inboard, when water level was lower than setting value, main pump started upwards cistern water supply, reach predetermined water level after, main pump stops, and reduces power consumption and quantity of circulating water; Water level meter 8 is housed in the overflow pond 6, and after overflow pond 6 water levels reach a certain height, overflow is returned water pump 7 and started, and was standby to upper water box the water pump in the overflow pond 6, reduced the hoisting depth of this part water, further energy-conservation.
Lower header 2 is operated in overflow situation, is used to keep water pressure invariableness, and upper water box 1 has sufficient volume retaining, strengthens instantaneous delivery when playing water spray, the standby effect of retaining in the time of intermittently; There are 2 groups of above same footpath or reducing pipelines that have rapidly opened and closed electromagnetic valve to be connected between two water tanks, the time and the group number that open and close according to the water spray electromagnetic valve come the switching combination of above-mentioned rapidly opened and closed electromagnetic valve is controlled, and according to the requirement of process for cooling the water yield of setting are ejected on the upper and lower surface of workpiece 14.
Upper water box 1 has regulating action, lower header 2 volumes can be less, be convenient to be arranged in the space or the nearer place of the distance water spray mouth of pipe, help reducing the space at drag losses and the crowded place of saving equipment, upper water box 1 can be arranged in abundant place, space, and adopt big volume, to strengthen the regulating power of the instantaneous water yield.
Owing to adopted upper water box 1, under same maximum instantaneous flow rate condition, the design discharge of main feed water pump 5 and power of motor can reduce, further electricity saving and energy saving, the employing of overflow pond 6 and valve group 3, reduced quantity of circulating water, alleviated the burden of water treatment facilities 12, the investment of water treatment system is greatly reduced.
The upper water box water supply and the water yield are shown in subordinate list.
