Abstract
The utility model relates to a raising-prevention device capable of removing the leaked liquid on line, which is characterized in that a leakage sensor is arranged inside the raising-prevention deviceto monitor the leaked liquid, and an air lifting pump is utilized to remove the leaked liquid. The air lifting pump is connected with the exterior through an air inlet pipe and a liquid outlet pipe,and compressed air is utilized to discharge the leaked liquid outside the pump body. The problem that the leaked liquid is remained caused by the invalid sealing inside the raising-prevention device can be solved, and the leaked liquid can be effectively monitored and can be discharged as expected.
Description
Technical field:
The utility model relates to fluid machinery.Refer in particular to a kind of lifting-proof machine that can online eliminating leakage liquid, the utility model can solve in the lifting-proof machine because seal failure causes the problem of leakage liquid delay, realizes effective monitoring leakage liquid and it is expelled to expection place.
Background technique:
If devices such as large diving pump generation power phase connects anti-phenomenon electric pump and will reverse, cause electric pump come-up (promptly lifting the machine phenomenon), in addition because pumping plant adopts quick flow-breaking devices such as flap valve more, might be after cutting off the electricity supply, aqueous reflux forms water flow passage top parital vacuum state, thereby produces hydraulic thrust upwards.The machine of the lifting phenomenon that produces might be twisted the safety that the outage cable greatly influences electric pump, so the general lifting-proof machine device that adopts prevents that phenomenon takes place here.In order to prevent that liquid from contacting with cable and cause damaging cable, the lifting-proof machine device is hermetic.But through working long hours, because seal failure in water and the wet goods leakage liquid inletting device, will make cable even motor damage.
The main path of head it off was a sealing configuration in the past, improved the reliability of sealing.But after the long-time long journey, seal failure can not be unavoidable.People such as Chen Qiang mention in " large-scale electric underwater pump self coupling system stability criterion and lifting-proof machine device " (mechanical facilities of irrigation and drainage in September, 2000) and improve the stability that seal ring increases the lifting-proof machine device.The cable protecting device of people such as the Dong Zhihao invention of Shanghai triumphant return pump industry Co., Ltd and lifting-proof machine structure (application number: be to adopt special structure to strengthen the effect of lifting-proof machine device 200620044423).All do not have to take measures at taking place to leak back eliminating liquid.Can only shut down maintenance when leakage problem takes place, maintenance process costs a lot of money.
Summary of the invention:
For addressing the above problem, the purpose of this utility model provides a kind of lifting-proof machine that can online eliminating leakage liquid, it not only is provided with leak sensor at lifting-proof machine internal leakage position, and the device of getting rid of leakage liquid is set, and can really and effectively leakage liquid be got rid of totally.
The technological scheme that realizes above-mentioned purpose is:
The utility model comprises top cover, base, connecting tube and connecting base, for making the sealing fully of devices such as lifting-proof machine device and pump, adopts Sealing assurance cable and liquid to isolate fully.In the connecting base bottom leak sensor is set, and with signal cable signal is transferred out, feature of the present utility model is: feature of the present utility model is the device of getting rid of leakage liquid to be set in the connecting base bottom get rid of leakage liquid and leak sensor is installed is come monitoring leakage liquid.
The device of described eliminating leakage liquid can be utilization gas and carries the airlift pump that mode is got rid of leakage liquid, and the suction port of airlift pump and liquid outlet link with suction tude and drain pipe respectively.
Described airlift pump is linked successively by suction port, nozzle, pick-up tube, receiving chamber, mixing tube, diffusing tube and liquid outlet and forms.
The utility model adopts pressurized air as power.During work, after leak sensor is reported to the police, open air compressor at once or other can provide the device of pressurized gas, make pressurized air enter airlift pump by suction tude, when pressurized gas arrives nozzle, the pressure of gas can be converted into kinetic energy, forms high-speed jet at jet expansion, and the lower liquid of pressure at the receiving chamber place is siphoned away.The turbulent fluctuation diffusion of jet boundary layer makes two fluid streams generation quality, momentum and energy interchange, so the speed of gas constantly reduces, the speed of liquid constantly increases, and gradually consistent in mixing tube speed, forms gas-liquid mixture.And in diffusing tube,, make its deceleration be pressurized to certain pressure edge and continue to carry, thereby discharge the pump housing with the drain pipe that airlift pump links because the expansion of pipe cross-section area makes the kinetic energy of fluid-mixing be converted into pressure energy.
The utility model is on probation through the user, and reaction is good, can reach the purpose of getting rid of leakage liquid, and this process operation is simple, and expense is also very cheap.

Embodiment
Embodiment
As shown in Figure 1, the utility model is provided with top cover (8), base (9), connecting tube (4) and connecting base (12), for lifting-proof machine device and submersible pump devices such as (14) is sealed fully, adopt the power cable (7) and the SC sigmal control cable (11) of Sealing (13) assurance pump to isolate fully with liquid.Be monitoring leakage liquid, in connecting base (12) bottom leak sensor (6) be set, and signal transferred out,, be provided with the airlift pump (5) that links with suction tude (3) and drain pipe (2) for getting rid of leakage liquid with signal cable (10).When by cable place seepage liquid, leak sensor (6) will be reported to the police, use the equipment of air compressor or other store compressed gases to charge into gas at once to suction tude (3), pressurized gas will enter airlift pump (5) by suction tude (3), device will be started working, and leakage liquid is taken out of to the precalculated position together by drain pipe (2).
Airlift pump (5) is by suction port (15), nozzle (16), and pick-up tube (17), receiving chamber (18), mixing tube (19), diffusing tube (20), liquid outlet (21) constitutes.As shown in Figure 2, pressurized gas is connected to the suction port (15) of airlift pump by suction tude (3), and when pressurized gas arrived nozzle (16), the pressure of gas can be converted into kinetic energy, go out the interruption-forming high-speed jet at nozzle (16), and the lower liquid of locating in receiving chamber (18) of pressure is siphoned away.The liquid of pick-up tube (17) just can add in the receiving chamber (18).The turbulent fluctuation diffusion of jet boundary layer makes two fluid streams generation quality, momentum and energy interchange, so the speed of gas constantly reduces, the speed of liquid constantly increases, and gradually consistent in mixing tube (19) speed, forms gas-liquid mixture.And in diffusing tube (20), because the expansion of pipe cross-section area, make the kinetic energy of fluid-mixing be converted into pressure energy, after liquid outlet (21) is located its deceleration to be pressurized to certain pressure, just can be expelled to predeterminated position, reach the purpose of getting rid of leakage liquid along the drain pipe (2) that links with liquid outlet.It is characterized in that: connecting base (12) bottom is provided with the air-lift device of getting rid of leakage liquid; The leak sensor that setting links to each other with air-lift device (6); The air-lift device of getting rid of leakage liquid is airlift pump (5), and the suction port (15) of airlift pump (5) and liquid outlet (21) link with suction tude (3) and drain pipe (2) respectively; Airlift pump (5) is by suction port (15), nozzle (16), and pick-up tube (17), receiving chamber (18), mixing tube (19), diffusing tube (20), liquid outlet (21) constitute to link successively and form.
