Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Existing slag stock pump has a lot of classification according to fed sheet of a media and itself structure, but structure is similar, and be all applicable to conveying slag slurry medium, general medium is not simple liquid medium, also likely contain block, even there is corrosivity, so, slag stock pump to flow passage part (in the present invention only for apron plate, these three kinds of flow passage parts of rear backplate and sheath launch, vane thickness monitoring device can certainly be set according to demand) have relatively high expectations, substantially adopt now wear-resistant material, but, because slag stock pump motion speed is very fast, even if adopt the flow passage part of wear-resistant material, also there is the periodically situation of wearing and tearing, if do not carry out checking in time, do not change or detect, after flow passage part wearing and tearing, under the centrifugal action of impeller, block in slag slurry medium easily punctures pump head, cause casualties, and stop production to overhaul in unplanned situation again, to manufacturing enterprise, bring massive losses, for this reason, the invention provides a kind of as Fig. 1, 3, a kind of slag stock pump with flow passage part excessive wear warning function shown in 4 and 5, comprise main shaft 5, seal arrangement, spiral case 2, apron plate 11, sheath 7 and rear backplate 3, also comprise and adopt ultrasonic thickness measurement mode to carry out the wear abrasion alarming device (referring to accompanying drawing 2) of flow passage part thickness Real-Time Monitoring, it comprises control module, probe group, alarm module and display modular, described probe group comprises three groups of ultrasonic wave thickness measuring probe groups, the first probe group 4 is located on rear backplate 3 outer side surfaces, described the second probe group 6 is located on sheath 7 outer peripheral surfaces, described the 3rd probe group 8 is located on apron plate 11 outer side surfaces, the signal end of described three groups of probe groups is connected with control module signal end, described alarm module control end is connected with control module control end, described display modular input end is connected with control module signal output part, described the first probe group 4 comprises at least three cover ultrasonic wave thickness measuring probes, three cover ultrasonic wave thickness measuring probes are evenly laid on rear backplate 3 outer side surfaces around main shaft 5 axis, described the second probe group 6 comprises at least six cover ultrasonic wave thickness measuring probes, six cover ultrasonic wave thickness measuring probes are evenly laid on sheath 7 outer peripheral surfaces around main shaft 5 axis after side by side between two, described the 3rd probe group 8 comprises at least three cover ultrasonic wave thickness measuring probes, three cover ultrasonic wave thickness measuring probes are evenly laid on apron plate 11 outer side surfaces around main shaft 5 axis.
In concrete application process, can directly adopt existing ultrasonic thickness gage, such as resonance thickness meter, the instruments such as interfere type ultrasonic thickness gauge and pulse reflection ultrasonic thickness gauge, utilize hyperacoustic refraction principle to detect the thickness of flow passage part, and the position of probe and quantity can be arranged on the position of easy wearing and tearing according to the flow passage part general feature of wearing and tearing, use control module that the one-tenth-value thickness 1/10 of measured thickness and setting is in advance compared simultaneously, utilize display modular to show check simultaneously, when recording thickness and be less than or equal to flow passage part critical thickness, control module is controlled alarm module and is reported to the police, remind operator's shutdown inspection replacing according to schedule, improve the planned of overhaul of the equipments, prevent that temporary cessation of production from bringing massive losses to enterprise, simultaneously, in the situation that effectively detecting, strictly stop the wearing and tearing of flow passage part in use or fall the generation of piece fault, ensure safety in production.
In a word, the present invention adopts ultrasonic thickness measurement mode to carry out the wear abrasion alarming device of flow passage part thickness Real-Time Monitoring by setting up, can in real time the thickness of flow passage components be detected in real time and be fed back, when its thickness is less than or equal to the critical value of setting, control gear is controlled alarm module and is reported to the police, and shows the thickness at corresponding probe position in display unit simultaneously, reminds operator to carry out planned stop production to overhaul, ensure safety in production, and can avoid the loss because stopping production and cause without plan.
