Description
Technical field
The present invention relates to a kind of down-hole water pump drainage arrangements, belong to mine mechanism technical field.
Background technology
Because subject to conditions in the operation of underground mines pump house, running environment is severe, and the artificial difficulty for observing water level is larger,
If water level is found not in time in operation, it is easy to damage the pump housing, influence the normal operation of drainage system, exist simultaneously and flood well
Security risk, therefore, when some cases of immersible pump change, it is very heavy that people can understand and take measures in time
It wants.
Invention content
According to the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to：A kind of down-hole water pump row is provided
Water installations so that operating personnel do not need the water level of running check sump, while start-stop draining pump easy to operation, have safety can
It leans on, labor-saving feature.
Down-hole water pump drainage arrangement of the present invention, including sump and the immersible pump that is placed in inside sump, immersible pump are logical
It crosses motor to be driven, liquid level sensor is equipped in sump, liquid level sensor is sequentially connected liquid level alarm, electricity by signal wire
Machine, sump bottom are equipped with steam(-)coil, and sump side wall is respectively equipped with nitrogen inlet, outlet of dropping a hint, and nitrogen inlet connects
Nitrogen pipeline, outlet connection emptying gas pipeline of dropping a hint, sump top connects inlet tube, inlet tube slope aspect sump.
Wherein：
The nitrogen pipeline is equipped with pressure controlling valve, and the connecting pipeline between pressure controlling valve and sump is equipped with pressure
Table.
It is equipped with stop valve between the sump and emptying gas pipeline.
Operation principle is as follows：
Water enters sump by inlet tube, and inlet tube with a slope can ensure that fluid flowing is smooth, when normal operation, diving
Water in sump is pumped to by pump to be needed to locate, and when liquid level sensor detects that liquid level is too low, liquid level alarm can send out alarm
Prompt, while motor operation is cut off, to ensure not damage the pump housing；When entering viscous material in sump, steam can be passed through
Steam pipe coil is heated, the fluid in sump is heated；After equipment runs a period of time, need to clean sump and blown
It sweeps, nitrogen is passed through by nitrogen pipeline, the pressure of the nitrogen in sump, purged nitrogen warp are entered by pressure controlling valve control
Emptying gas pipeline is discharged.
Advantageous effect possessed by the present invention is：
The configuration of the present invention is simple solves the drainage problem of down-hole water pump, by installing liquid level sensor and alarm, behaviour
The water level in running check sump is not needed as personnel, is convenient for start-stop draining pump.

Stop valve.
Specific implementation mode
The embodiment of the present invention is described further below in conjunction with the accompanying drawings：
As shown in Figure 1, down-hole water pump drainage arrangement includes sump 1 and the immersible pump 5 that is placed in inside sump, immersible pump 5 is logical
It crosses motor 4 to be driven, liquid level sensor 2 is equipped in sump 1, liquid level sensor 2 is sequentially connected liquid level warning by signal wire
Device 3, motor 4,1 bottom of sump are equipped with steam(-)coil 6, and 1 side wall of sump is respectively equipped with nitrogen inlet 10, outlet 9 of dropping a hint,
Nitrogen inlet 10 connects nitrogen pipeline 12, and 9 connection emptying gas pipeline 11 of outlet of dropping a hint, 1 top of sump connects inlet tube 14, enters
Mouth 14 slope aspect sump 1 of pipe.Wherein, nitrogen pipeline 12 is equipped with pressure controlling valve 8, the connection between pressure controlling valve 8 and sump 1
Pipeline is equipped with pressure gauge 7, and stop valve 13 is equipped between sump 1 and emptying gas pipeline 11.
