Abstract
The invention relates to an anti-lift device which can exclude leakage liquid; a leakage sensor is arranged in the anti-lift device for monitoring the leakage liquid and an electric pump is installed for excluding the leakage liquid. The electric pump is connected with the outside world by a power cable and a liquid outlet pipe thereof, which can solve the problem that sealing failure results in the retention of the leakage liquid in the anti-lift device, realizes effective monitoring of the leakage liquid and discharging the leakage liquid to an expected place.
Description
Technical field:
The present invention relates to fluid machinery.Refer in particular to a kind of lifting-proof machine that can get rid of leakage liquid, the present invention can solve the problem that causes leakage liquid to be detained owing to seal failure in the lifting-proof machine, realizes effective monitoring leakage liquid and it is expelled to expection place.
Background technique:
If generation such as large diving pump power phase connects anti-phenomenon electric pump and will reverse, cause submersible pump come-up (promptly lifting the machine phenomenon), in addition because pumping plant adopts quick flow-breakings 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 that adopts prevents that phenomenon takes place here.In order to prevent that liquid from contacting with cable and cause damaging cable, lifting-proof machine is hermetic.But through working long hours, because seal failure in leakage liquid enters, 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 " (mechanical facilities of irrigation and drainage in September, 2000) and improve the stability that seal ring increases lifting-proof machine.The cable protection 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 200620044423).But all do not have at present to take measures at taking place to leak back eliminating liquid.
Summary of the invention:
For addressing the above problem, the purpose of this invention is to provide a kind of lifting-proof machine that can get rid of leakage liquid, it not only is provided with leak sensor at lifting-proof machine internal leakage position, and an electric pump is set gets rid of leakage liquid, can really and effectively leakage liquid be got rid of.
The technological scheme that realizes above-mentioned purpose is:
The present invention includes top cover, base, connecting tube and connecting base, seal fully, adopt Sealing that the machine phenomenon is lifted in lifting-proof machine and bottom, guarantee that cable and liquid isolates fully for making lifting-proof machine and pump etc.In the connecting base bottom leak sensor is set, and signal is transferred out with signal cable, feature of the present invention is: feature of the present invention is to be provided with the electric pump of getting rid of leakage liquid in connecting base bottom, and electric pump and cable and drain pipe link, and the leak sensor that links to each other with electric pump of setting.
After leak sensor is reported to the police, open electric pump at once, leakage liquid is excluded.
The invention has the beneficial effects as follows through the user and use that effect reaction is good, and this process operation is simple, expense is also very cheap.

Embodiment
Embodiment
As shown in Figure 1, the present invention is provided with top cover (8), base (9), connecting tube (4) and connecting base (12), for lifting-proof machine and submersible pump (14) etc. are 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 electric pump (5) that links with electric pump cable (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, and opens electric pump (5) at once, and electric pump will be started working, and leakage liquid is taken out of to the precalculated position by drain pipe (2).
More than, for the present invention is specifying that embodiment did with the electric pump, but, electric pump not only can install with lifting-proof machine in, also can be installed in outside the lifting-proof machine.Moreover the position of offering of cable and the drain pipe of utilization electric pump also is not limited to upper end at lifting-proof machine, complies with the possibility that its service condition can also be placed on other positions of lifting-proof machine.Downside of the present invention is exemplified as submersible pump, but not only is used for submersible pump, also can be used for other and lift the machine phenomenon.
Claims (3)
1. the lifting-proof machine that can get rid of leakage liquid, it comprises and is provided with the Sealing (13) that top cover (8), base (9), connecting tube (4) and connecting base (12) and the following device of lifting the machine phenomenon connect, leak sensor (6) also is set, it is characterized in that: described connecting base (12) bottom is provided with electric pump (5) and gets rid of leakage liquid.
2. a kind of lifting-proof machine that can get rid of leakage liquid according to claim 1 is characterized in that, the leak sensor (6) that links to each other with electric pump (5) is installed is come monitoring leakage liquid.
3. a kind of lifting-proof machine that can get rid of leakage liquid according to claim 1 is characterized in that, electric pump (5) links with electric pump cable (3) and drain pipe (2) respectively.
