Abstract
The utility model relates to an intelligent apparatus for a protecting and monitoring submerged pump with a long shaft, which is composed of the submerged pump with a long shaft, wherein a pump shaft is arranged in the submerged pump with a long shaft, one end of the pump shaft is arranged in a pump seat and is supported by a bearing, and the other end is supported by a guide bearing; the pump shaft is sheathed in a sealing sheath which is positioned between the pump seat and the guide bearing, a sealing cavity is arranged between the sealing sheath and the pump shaft and is filled with sealing injecting water, and a flow sensor is arranged in the sealing cavity and is connected with a controller through lead wires. The flow sensor can carry out real-time detecting of the flow quantity of the sealing injecting water, and the controller can judge whether the gaps reach the fatigue degree of the guide bearing according to the flow quantity of the sealing injecting water and the relation of gaps of the guide bearing and the sealing sheath. The utility model can accurately monitor the actual wear degree of the guide bearing in time.
Description
Technical field:
The utility model relates to fluid delivery system, relates in particular to the long shaft submerged pump with automat structure, particularly a kind of intelligent protection monitoring long shaft submerged pump device.
Background technique:
In the prior art, long shaft submerged pump is widely used in power plant and send water, needs operation continuously in 24 hours.Will influence production in case break down, when serious even can influence the Host Security operation.The fault statistics data show that the main cause that causes the major axis pump work to lose efficacy is bearing failure.In order to take precautions against failure accidents, power plant's periodical repair, rather than overhaul according to the wearing and tearing or the part failure degree of pump reality.Therefore sometimes can overhaul during also in better running state, increase maintenance cost, cause waste at pump; Sometimes equipment damages in advance, and as high temperature wear, and also have the long time lag from the time limit of maintenance this moment, and equipment can not in time be overhauled.
Summary of the invention:
Technical problem of the prior art to be solved in the utility model is: in the prior art, can't judge the wearing and tearing or the part failure degree of long shaft submerged pump reality, cause maintenance unreasonable opportunity.
The utility model provides a kind of intelligent protection monitoring long shaft submerged pump device for the technological scheme that the problems referred to above adopted that solves in the prior art; described this intelligent protection monitoring long shaft submerged pump device is made of a long shaft submerged pump; be provided with a pump shaft in the described long shaft submerged pump; one end of described pump shaft is arranged in the pump seat and by bearings; the other end of described pump shaft is supported by at least one guide bearing; the outside of described pump shaft is arranged with a sealing sheath; described sealing sheath is between pump seat and guide bearing; be provided with Seal cage between sealing sheath and the pump shaft; be provided with the sealing water filling in the described Seal cage; the outside of described sealing sheath is arranged with an overcoat; described overcoat is connected with pump seat; wherein; be provided with a flow transducer in the described Seal cage, the signal output part of described flow transducer is connected by the signal input port of lead with a controller.
Further, the bearing that supports pump shaft in the described pump seat is provided with bearing temperature rise sensor and vibration transducer, and the signal output part of described bearing temperature rise sensor and vibration transducer is connected with the signal input port of described controller by lead respectively.
Further, described controller is programmable controller or single-chip microcomputer.
Working principle of the present utility model is: the sealing sheath in the pump shaft outside is isolated the sealing water filling of lubricated guide bearing in fed sheet of a media and the sealing sheath, makes the sealing water filling of cleaning play a part lubricated guide bearing.Because the working pressure of sealing water filling is constant, if not wearing and tearing of guide bearing, the gap between guide bearing and the pump shaft just remains unchanged, and according to fluid mechanics as can be known, the flow of sealing water filling also can remain unchanged; After guide bearing wearing and tearing, the gap between guide bearing and the pump shaft will increase, and under the constant situation of the working pressure of sealing water filling, the flow of sealing water filling will increase thereupon; Detect the flow that seals water filling in real time by the flow transducer that is arranged in the Seal cage, and flux signal is delivered to controller, controller is according to the flow of sealing water filling and the relation in the gap between guide bearing and the sealing sheath, adopt the method for fluid numeric value analysis, can calculate the relation of gap and inefficacy, draw the minimum inefficacy flow value of guide bearing.When the detected flow value of flow transducer during greater than the minimum inefficacy flow value of guide bearing, monitor program in the controller can be sent alarm command to alarm, prompting is overhauled, and simultaneously, shows the guide bearing wear intensity of being converted out by the flow of sealing water filling in real time on the bearing state display device.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is provided with flow transducer between sealing sheath and pump shaft, utilize flow transducer to detect the flow of sealing water filling, thereby obtain the state of development of the wearing clearance of guide bearing, monitors the actual wear degree of guide bearing real-time and accurately.
