Abstract
An intelligent protective monitoring water circulating pump comprises a pump body, on which a pump cap is provided and within which a pump shaft is provided and positioned in a guide bearing that is arranged within the pump body. One end of the pump shaft passes through the pump cap and connects with output shaft of a motor which is equipped fixedly at outer side of the pump cap. Outer side of the pump shaft and the guide bearing is provided with a sealed cooling water device. Outer side of the guide bearing is provided with a flow sensor, and the signal output end of the flow meter connects with signal input port of a controller via a cable. The guide bearing has a bearing temperature rise sensor and a vibration sensor, and the signal output ports of the vibration sensor respectively connect with the signal input port of the controller via cables. The gap between the guide bearing and the shaft sleeve is calculated by the flow detected by the flow sensor, and then the bearing failure time is estimated according to the gap-failure curve. The bearing temperature rise sensor and the vibration sensor may conduct real-time monitoring of mechanical failures due to bearing malfunctions.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to fluid delivery system, particularly circulating water pump, and concrete is a kind of intelligent protection monitoring circulating water pump.
Background technique:
In the prior art, circulating water pump is widely used in power plant and carries main frame circulating water, and circulating water pump and main frame synchronous operation need twenty four hours to move continuously.In a single day circulating water pump breaks down will influence production, when serious even can influence the Host Security operation.Fault statistics data to circulating water pump show that the main cause that causes the circulating water pump operational failure is bearing failure.There are a plurality of guide bearings circulating water pump inside, and guide bearing supports pump shaft, and guide bearing is equipped with the sealing chilled water unit outward, and the sealing chilled water unit is isolated fed sheet of a media and guide bearing sealing water, makes the sealing water filling of cleaning play a part lubricated guide bearing.It is the most incident fault of circulating water pump that guide bearing lost efficacy.Because guide bearing under liquid, is difficult to it is carried out on-line monitoring with conventional method.For failure accidents is taken precautions against in possible trouble, power plant generally is a periodical repair rule of thumb, rather than overhauls according to the wearing and tearing or the part failure degree of pump reality.Therefore, tend to carry out unnecessary maintenance during also in better running state, increased maintenance cost, cause waste at pump; Perhaps damage in advance, during as high temperature wear, also have the long time lag, equipment can not in time be overhauled from the time limit of experience maintenance at equipment.
Summary of the invention:
The purpose of this utility model provides a kind of intelligent protection monitoring circulating water pump, and described this intelligent protection monitoring circulating water pump will solve the guide bearing wearing and tearing that can't monitor circulating water pump in the prior art in real time or the technical problem of part failure situation.
This intelligent protection monitoring circulating water pump of the present utility model is made of a pump housing; the described pump housing is provided with a pump cover; be provided with a pump shaft in the pump housing; described pump shaft is arranged in the guide bearing of an above number; described guide bearing is arranged in the pump housing; the outside of pump cover is set with a motor; one end of pump shaft passes pump cover and is connected with the output shaft of motor; the arranged outside of pump shaft and guide bearing has the sealing chilled water unit; be provided with water outlet in the pump housing; wherein, the arranged outside of described guide bearing has a flow transducer, and the signal output part of described flow transducer is connected by the signal input port of lead with a controller.
Further, the guide bearing in the described pump housing 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, be provided with a pressure transducer in the described water outlet, the signal output part of described pressure transducer is connected by the signal input port of lead with a controller.
Further, described controller is made of programmable logic controller (PLC) or single-chip microcomputer.
Further, described pump shaft is connected with the output shaft of motor by coupling.
Working principle of the present utility model is: in the sealing chilled water unit outside guide bearing, the working pressure of sealing water filling is constant, there is substantial connection in the flow of sealing water filling and the gap between guide bearing and the axle sleeve, adopt the method for fluid numeric value analysis, can calculate the relation of gap and inefficacy.Therefore detect by flow transducer and obtain flow value, the curved line relation of gap and inefficacy according to the relation of gap and pump work state, can be calculated in the gap of calculating guide bearing and axle sleeve again by flow value.This relation curve is compiled into program, implants in the programmable logic controller, programmable logic controller just can effectively be monitored the working state at guide bearing position.Bearing temperature rise sensor and vibration transducer at bearing portion can be monitored damage of bearings, coupling fault etc.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is by the arranged outside flow transducer at guide bearing, detection obtains flow value, calculate the gap of guide bearing and axle sleeve by flow value, can be by the curved line relation prediction bearing failure time of gap and inefficacy, in addition, can realize monitoring in real time to the mechanical failure that bearing causes by bearing temperature rise sensor and vibration transducer.
