Abstract
The invention relates to the technical field of boiler detection systems and particularly relates to a novel non-ferromagnetic encoder. The encoder comprises an encoder wheel (1), a main rotation shaft (2), a shell (3), a photoelectric reading head (4), a photoelectric encoder (5) and a bearing (6), wherein the upper end and the lower end of the main rotation shaft (2) are fixed inside the middle of the shell (3) through the bearing (6), the photoelectric encoder (5) is fixed in the middle of the main rotation shaft (2), and the photoelectric reading head (4) is arranged at the right side of the photoelectric encoder (5); and the encoder wheel (1) is fixed at the top of the upper end of the main rotation shaft (2). The encoder has no influence on the detection result on a magnetic detection system, besides the functions of the existing encoder, so that the detection result is relatively accurate.
Description
Technical field
The present invention relates to boiler exam systems technology field, be specifically related to a kind of novel nonferromagnetic scrambler.
Background technology
Can produce oxide skin for a long time in Austenitic stainless steel pipe in heat power plant boiler, and oxide skin is ferromagnetic material, generally magnetic detecting technique is adopted to its detection.Carrying out in magnetic detection process to oxide skin tamper, in order to realize the real-time display (position display and content display) to pipe internal oxidition skin, on its pick-up unit, scrambler must be installed.Because the principle detected gathers based on to the magnetic signal of oxide skin, the scrambler therefore used must be nonferromugnetic material.Existing scrambler itself is all that band is ferromagnetic in the market, carrying out oxide skin will bringing interference in magnetic detection process, makes testing result inaccurate.
Summary of the invention
The object of this invention is to provide a kind of novel nonferromagnetic scrambler, it has outside existing scrambler all functions, when can also realize on magnetic detection system on testing result without impact, make testing result more accurate.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it comprises encoder wheel, main rotating shaft, shell, photoelectricity read head, photoelectric code disk, bearing; The two ends up and down of described main rotating shaft are fixed on the inside middle of shell by bearing, the centre of main rotating shaft is fixed with photoelectric code disk, and the right side of photoelectric code disk is provided with photoelectricity read head; The top, upper end of main rotating shaft is fixed with encoder wheel.
Described bearing is embedded in the preformed groove at the upper and lower two ends of shell.
Beneficial effect of the present invention: it has outside existing scrambler all functions, when can also realize on magnetic detection system on testing result without impact, make testing result more accurate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is exploded view of the present invention.
Reference numeral: encoder wheel 1, main rotating shaft 2, shell 3, photoelectricity read head 4, photoelectric code disk 5, bearing 6.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with the drawings and the specific embodiments, the present invention is further elaborated.Should be appreciated that embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Referring to Fig. 1, this embodiment by the following technical solutions: it comprises encoder wheel 1, main rotating shaft 2, shell 3, photoelectricity read head 4, photoelectric code disk 5, bearing 6; The two ends up and down of described main rotating shaft 2 are fixed on the inside middle of shell 3 by bearing 6, the centre of main rotating shaft 2 is fixed with photoelectric code disk 5, and the right side of photoelectric code disk 5 is provided with photoelectricity read head 4; The top, upper end of main rotating shaft 2 is fixed with encoder wheel 1.
Described encoder wheel 1 has nylon material to process, and what bearing 6 was selected is ceramic bearing, is connected respectively with austenitic stainless steel main rotating shaft 2; Photoelectricity read head 4 and photoelectric code disk 5 during encoder core parts; Photoelectric code disk 5 adopts plastic material, is connected with main rotating shaft 2, and photoelectricity read head 4 and photoelectric code disk 5 are pressed ad-hoc location and installed.
Described photoelectric code disk 5 partially opens several slots on the plectane of certain diameter, and photoelectricity read head is the pick-up unit of an electronic component composition; Photoelectricity read head 4 has a specific installation site, and this position must ensure that the detecting element of its top is corresponding with the slot on photoelectric code disk.Because photoelectric code disk 5 is coaxial with encoder wheel 1, when encoder wheel 1 rotates, photoelectric code disk 5 and the synchronized rotation of encoder wheel 1, detect through photoelectricity read head 4 and export some pulse signals, realize its effect.
The beneficial effect of this embodiment: it has outside existing scrambler all functions, when can also realize on magnetic detection system on testing result without impact, make testing result more accurate.
The above, only in order to technical scheme of the present invention to be described and unrestricted, other amendment that those of ordinary skill in the art make technical scheme of the present invention or equivalently to replace, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of right of the present invention.
