Abstract
The utility model relates to a blast furnace tapping machine hydraulic system, including a No. one main pump (1), a No. two main pump (2), a No. three main pump (3) and three main pump petroleum pipe lines namely a No. one main pump petroleum pipe line (9), a No. two main pump petroleum pipe line (10) and a No. three main pump petroleum pipe line (11); a switching valve (8) is arranged on the No. one main pump petroleum pipe line (9) and the No. three main pump petroleum pipe line (11), the switching valve (8) is composed of a communicating pipe (4), a switching valve (5), a switching valve (6), a switching valve (7); the No. three main pump petroleum pipe line (11) is communicated with the No. one main pump petroleum pipe line (9) by the communicating pipe (4); the switching valve (6) is arranged on the communicating pipe (4); the switching valve (5) is arranged on the No. one main pump petroleum pipe line (9) which is behind the communicating pipe (4); the switching valve (7) is arranged on the No. three main pump petroleum pipe line (11) which is behind the communicating pipe (4). All the three main pumps of the utility model can be taken as a spare pump each other by means of switching operation, the No. one main pump can replaces the No. three main pump to offer operation pressure so as to help the tapping machine to backtrack to the primary place, and therefore the vicious equipment accident can be avoided.
Description
Technical field:
The utility model relates to a kind of tap hole of blast furnace, especially relates to a kind of tap hole of blast furnace stokehold hydraulic efficiency system.Belong to the blast furnace steel-making technical field.
Background technology:
The stokehold hydraulic efficiency system is the propulsion source of tap hole of blast furnace work.Its 1#, 2#, 3# main pump can not be standby each other, and the 3# main pump is that control taphole drilling machine hook swings up and down, if the iron mouth is held successfully, the iron mouth flows out, 3# main pump or electric catastrophic failure, and the taphole drilling machine hook just can not lift and return raw bits.Scorch down at high temperature liquid iron like this, the short several minutes time, a taphole drilling machine that is worth 260,000 yuan will be burnt, and stops production and changes spare part also at least 5～6 hours, will produce a very large impact blast furnace production.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can make 1#, 2#, the standby each other tap hole of blast furnace stokehold hydraulic efficiency system of 3# main pump.
The purpose of this utility model is achieved in that a kind of tap hole of blast furnace stokehold hydraulic efficiency system, comprise: the 1# main pump, the 2# main pump, 3# main pump and go out 1# main pump pipeline road, go out 2# main pump pipeline road and go out 3# main pump pipeline road, it is characterized in that: going out 1# main pump pipeline road and going out addition one switching valve group on the 3# main pump pipeline road, this switching valve group is by communicating pipe, switching valve, switching valve and switching valve constitute, to go out 1# main pump 1 pipeline road communicating pipe and go out 3# main pump 3 pipeline roads to be connected, switching valve was arranged on communicating pipe, switching valve is arranged at going out on 1# main pump 1 pipeline road behind the siphunculus in succession, and switching valve is arranged at going out on 3# main pump 3 pipeline roads behind the siphunculus in succession.
The utility model can make 1# main pump, 2# main pump, 3# main pump standby each other, and system operation is simple, convenient, as long as switch, the 1# main pump just can replace the 3# main pump to provide pressure to operate, make taphole drilling machine return raw bits, also just can avoid pernicious equipment breakdown to take place, also satisfy the big production needs of blast furnace simultaneously.
Description of drawings:
Fig. 1 is the utility model tap hole of blast furnace stokehold hydraulic system principle figure.
Among the figure: 1# main pump 1,2# main pump 2,3# main pump 3, communicating pipe 4, switching valve 5, switching valve 6, switching valve 7, switching valve group 8, go out 1# main pump 1 pipeline road 9, go out 2# main pump 2 pipeline roads 10, go out 3# main pump 3 pipeline roads 11, hook hydro-cylinder 12, other topworkies 13, clay gun valve platform 14.
Embodiment:
Referring to Fig. 1, tap hole of blast furnace stokehold hydraulic efficiency system mainly is made up of 1# main pump 1,2# main pump 2,3# main pump 3, communicating pipe 4, switching valve 5, switching valve 6 and switching valve 7.Communicating pipe 4, switching valve 5, switching valve 6 and switching valve 7 constitute switching valve group 8.
The pipeline road 9,11 that will go out 1# main pump 1 and 3# main pump 3 communicating pipe 4 is connected.Switching valve 6 was arranged on communicating pipe 4, and switching valve 5 is arranged at going out on 1# main pump 1 pipeline road 9 behind the siphunculus 4 in succession, and switching valve 7 is arranged at going out on 3# main pump 3 pipeline roads 11 behind the siphunculus 4 in succession.
Principle of work:
When 3# main pump or electric catastrophic failure, close switching valve 5, open switching valve 6, the 1# main pump just can replace the 3# main pump to provide pressure to operate, and makes taphole drilling machine turn back to raw bits.
