Description
Technical field
The utility model relates to the water pump field, and particularly a kind of mine is with the novel suction drainage plant of feeding water pump and drainage pump Combination application.
Background technology
The drainage system of mine use at present only adopts the scheme of multistage drainage pump; This will not have water or come cisco unity malfunction operation under the insufficient operating mode of water; Because original drainage pump should absorb water; Draining again, and suction head must satisfy more than 6 meters, is quite harsh to multistage water pump.
Hang in vacuum that water is insufficient, entrance pipe sealing leak, water pump first order damage in impeller, arbitrary situation such as cavitation performance decline, entrance pipe obstruction all can cause the multistage drainage pump can't operate as normal when taking place, cause damp production.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned not enough problem; A kind of mine is proposed with feeding water pump drainage pump combined water drain equipment; This drainage plant be except effectively satisfying the requirement of mine drainage, and the performance that can also improve the drainage helps improving the efficient of drainage plant; And improving the operation stability of drainage plant on the whole, practicality is stronger.
The technical scheme that the utility model adopts is: a kind of new type mining suction drainage plant; Comprise and feed pump installation, pressure meter, drainage pump device, pressure gauge and mobile vacuum exhaust system; Feed the pump installation suction side and insert among the sump The Small Well, feed the pump installation water side and be connected with drainage pump device portal end, pressure meter is installed on feeds the pump installation water side; The mobile vacuum exhaust system is installed on feeds on the pump installation, and pressure gauge is installed on the drainage pump device port of export.
The said pump installation of feeding adopts hello pump sump duct member one end to connect among the sump The Small Well; The other end is connected in feeds on the pump sump end; Feed the water pump discharge pipe part and be installed on hello water pump water outlet end, the mobile vacuum exhaust system is installed on feeds on the water pump discharge pipe part.
Said drainage pump device adopts the drainage pump arrival end to be connected in and feeds on the water pump discharge pipe part, and installation outlet non retern valve, drainage pump export gate valve and export pipeline to the drainage pump port of export successively from bottom to top.
The utility model compact conformation compared with prior art has following characteristics and advantage:
1, drain function and the negative pressure absorbent function that former drainage pump will be realized are separately realized; Realize entrance negative pressure absorbent function (hanging reasons such as water deficiency, sealing leak, entrance pipe obstruction because of vacuum in the solution draining can't absorb water) with feeding water pump; With the drain function of drainage pump realization pump, guarantee that an equipment solves a function.
2, in the water pump automated system, occur because the gas leakage of drainage pump filler and phenomenon that can't turn on pump through regular meeting; Mainly be that filler leaks gas through regular meeting because during with the draining of separate unit drainage pump, entering the mouth is negative pressure; Feed water pump hello water and adopt; The drainage pump inlet is malleation forever, and filler just can not leak gas, and thorough solution is the problem of turn on pump normally.
3, adopt the application scheme of feeding water pump and drainage pump combination to change traditional coal-mine water-house design concept; Drainage pump can design directly over sump; More help improving the bulk life time of drainage system and being convenient to the structure design in next coal seam, and improve its life-span.
4, can realize drainage system automation and unmanned, from the environment of spiritual high concentration, free the workman, reduce labour intensity, improve personal safety.
The utility model system can be widely used in the conveying of the single-phase or heterogeneous fluid in fields, mine such as colliery, iron ore, gold mine.
To sum up, the utility model can provide function practicality, the high new type mining suction of efficient drainage plant, has the safety factor height, good reliability, the advantage that practicality is stronger.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of facing of new type mining suction drainage plant.
Accompanying drawing 2 is a kind of plan structure sketch map of new type mining suction drainage plant.
Among the figure: 1 feeds water pump; 2 drainage pumps outlet gate valve; 3 pressure gauges; 4 drainage pumps; 5 pressure meters; 6 outlet non retern valves; 7 feed the pump sump duct member; 8 feed the water pump discharge pipe part; 9 mobile vacuum exhaust system; 10 export pipelines.
The specific embodiment
Specify the utility model below in conjunction with accompanying drawing, but the utility model is not limited to specific embodiment.
With shown in the accompanying drawing 2, a kind of new type mining suction of the utility model drainage plant comprises and feeds pump installation, pressure meter 5, drainage pump device, pressure gauge 3 and mobile vacuum exhaust system 9 like accompanying drawing 1.
Feeding the pump installation suction side inserts among the sump The Small Well; Feeding the pump installation water side is connected with drainage pump device portal end; Pressure meter 5 is installed on feeds the pump installation water side, and mobile vacuum exhaust system 9 is installed on feeds on the pump installation, and pressure gauge 3 is installed on the drainage pump device port of export.
Feeding pump installation adopts hello pump sump duct member 7 one ends to connect among the sump The Small Well; The other end is connected in feeds on water pump 1 suction side; Feed water pump discharge pipe part 8 and be installed on hello water pump 1 water side, mobile vacuum exhaust system 9 is installed on feeds on the water pump discharge pipe part 8.
The drainage pump device adopts drainage pump 4 arrival ends to be connected in and feeds on the water pump discharge pipe part 8, and installation outlet non retern valve 6, drainage pump export gate valve 2 and export pipeline 10 to drainage pump 4 ports of export successively from bottom to top.
Water in the sump The Small Well is through feeding water pump 1; Drainage pump 4 is discharged by discharge pipe line again, is the single stage pump of the big flow low lift of the strong low speed of the ability of sucting owing to feed water pump; And the drainage pump high-lift multi-stage, efficient pump that is high-speed large-flow forms the equipment that water pump assembly and drainage pump unit make up of feeding.
Before device start, need carry out the inspection work before the import and export pipeline connects situation and each pump startup, guarantee that the outlet gate valve 2 on the export pipeline 10 is closed.
During startup, open the drain tap on the mobile vacuum exhaust system 9 intermediate pump pipelines earlier, the vacuum pump unit is connected to valve open on the suction line; Start the vacuum pump unit then; When the vacuum pump discharge is discharged gas-liquid mixture, can start and feed water pump assembly, behind hello the starting mode of pump, start the drainage pump unit; Close vacuum pump, open the outlet gate valve on the drainage pump export pipeline
Should notice that when starting drainage pump the ammeter index in the power distribution cabinet can not surpass the rated current of motor, the valve on the adjustment drainage pump export pipeline is stabilized in about the rated current of motor electric current as far as possible.
No matter take which kind of mode start-up system, when stopping, must abide by following order and carry out: close the export pipeline non retern valve earlier, after close drainage pump, close at last and feed water pump.
Must close outlet valve earlier during system shutdown,, destroy drainage pump in order to avoid cause " water hammer " phenomenon., drainage pump must guarantee to feed water pump before cutting out constantly in running status.
