Ni ibihe bintu bigomba kwitabwaho mu gushyiraho icyuma gipima amashanyarazi gikoresha ikoranabuhanga rya clamp-on?

Mu gushyiraho icyuma gipima amashanyarazi gikoresha ikoranabuhanga rya clamp-on, hagomba kwitabwaho ibintu byinshi nko kuba imiyoboro y'amazi imeze neza, aho sensor ishyirwa, n'ibijyanye n'ibidukikije kugira ngo harebwe ko ibipimo ari ukuri kandi ko ibikoresho bihamye. Dore ingamba zihariye zo kwirinda:

I. Igenzura ry'imiterere y'ibanze y'imiyoboro y'amazi

1. Ibikoresho by'imiyoboro n'ubunini bw'urukuta
   • Ibikoresho byo gupima ibyuma byifashisha imiraba ya ultrasonic yinjira mu muyoboro kugira ngo ikwirakwizwe. Kubwibyo, umuyoboro ugomba kuba ukozwe mu bikoresho bitari ibyuma (nka PVC, PE) cyangwa ibikoresho by'icyuma bifite inkuta nto (nk'icyuma kitagira umugese, icyuma cya karuboni, gifite ubugari bw'urukuta busanzwe busabwa kuba ≤ 10mm).
   • Niba urukuta rw'imbere rw'umuyoboro rufite urwego rurwanya ingese, uburebure, cyangwa urwego rurwanya ingese (nk'isima, urwego rwa rubber), ni ngombwa kwemeza ko ubunini bwarwo bungana kandi ko butagira ingaruka ku ihererekanya ry'amajwi; bitabaye ibyo, amakosa yo gupima ashobora kubaho.
2. Ingano y'umuvuduko w'imiyoboro n'uruhererekane rw'umuvuduko w'amazi
   • Menya neza ko urwego rwo gupima flowmeter ruhuye n'umurambararo w'imiyoboro n'umuvuduko nyawo w'amazi (muri rusange, ubwoko bw'imiyoboro ikoreshwa mu gufunga amashanyarazi bukwiriye imiyoboro ifite DN15 ~ DN6000, kandi umuvuduko w'amazi ubusanzwe usabwa kuba 0.3 ~ 12m / s).
   • Umuvuduko muke cyane w’amazi (<0.3m/s) ushobora gutuma ibimenyetso bidakora neza, kandi umuvuduko mwinshi cyane w’amazi (>12m/s) ushobora kugira ingaruka ku gupima bitewe n’umuvuduko.
3. Ubutegetsi buri hagati mu muyoboro
   • Icyo gikoresho kigomba kuba ari amazi y’icyiciro kimwe (amazi adafite uduheri twinshi, uduce duto, cyangwa imyanda). Bitabaye ibyo, uduheri cyangwa uduce duto tuzagaragaza/dukwirakwiza amajwi, bigatuma ibimenyetso cyangwa amakosa bitagaragara.
   • Irinde gutandukanya ibintu, imiraba, cyangwa umuyaga mwinshi w’amazi mu muyoboro (nk’aho hafi ya valves na pompes), kandi urebe neza ko igice cyo gupimiramo gitembera neza mu muyoboro wuzuye.

II. Guhitamo aho sensor ishyirwa

1. Ibisabwa ku gice cy'imiyoboro igororotse
   • Kugira ngo habeho imiterere ihamye y'amazi atembera, aho sensor ishyirwa hagomba kuba hujuje ibisabwa ku burebure bw'ibice by'imiyoboro igororotse mbere na nyuma:
     • Hejuru (uruhande ruri kure y'icyuma gipima): Niba hari inkokora, valve, pompe, cyangwa ibindi bice birwanya imbere, bigomba kuba inshuro ≥ 10 z'umurambararo w'umuyoboro (10D); niba nta bice bito bihari, bigomba kuba ≥ 5D.
     • Munsi y'amazi (uruhande rwegereye sensor): ≥ 5D (niba hari ibice by'ubudahangarwa biri munsi y'amazi, ni byiza kuba ≥ 3D).
   • Irinde gushyira ahantu hirengeye cyane h'umuyoboro (aho umwuka ushobora kwirundanya) cyangwa ahantu ho hasi cyane (aho ibisigazwa bishobora kwirundanya).
2. Icyerekezo cyo gushyiraho n'aho gushyiramo
   • Ukurikije ibikoresho by'umuyoboro n'umurambararo, hitamo uburyo bwa V (imiraba y'amajwi inyura mu muyoboro mu buryo butaziguye, bukwiriye umurambararo muto n'uciriritse) cyangwa uburyo bwa Z (imiraba y'amajwi inyura mu muyoboro mu buryo butaziguye, bukwiriye umurambararo munini cyangwa imiyoboro ifite inkuta nini).
   • Ibikoresho bibiri by'ikoranabuhanga (impera yo kohereza n'impera yo kwakira) bigomba gushyirwaho ku mpande zombi z'umuyoboro kugira ngo inzira y'urusaku rw'amajwi ifatanye n'umurongo w'umuyoboro, kandi intera ijyanye n'uburyo bwo kubara buri mu gitabo cy'amabwiriza y'urusaku rw'amajwi (ubusanzwe bifitanye isano n'umurambararo w'umuyoboro n'inguni y'urusaku rw'amajwi).
3. Irinde ko hari aho byabangamira abantu
   • Irinde ahantu hakomeye hashobora kwangiza ingufu z'amashanyarazi (nk'amamoteri, transformateur, frequencies) kugira ngo wirinde ko ibimenyetso by'amashanyarazi byabangamira uburyo bwo kohereza amashanyarazi hakoreshejwe ikoranabuhanga.
   • Bika kure y'aho ibintu binyura (nk'ipompo, compressors). Niba bibaye ngombwa, shyiramo udupapuro dufata amashanyarazi kugira ngo wirinde ko sensor ifata nabi bitewe n'uko imiyoboro inyura.

III. Ibisobanuro birambuye ku mikorere yo gushyiraho sensor

1. Uburyo bwo gutunganya imiyoboro y'amazi
   • Mbere yo gushyiraho, sukura ubuso bw'umuyoboro kugira ngo ukureho ingese, irangi, amavuta, cyangwa oxide kugira ngo urebe neza ko sensor n'umuyoboro bihura neza (nibiba ngombwa, umucanga ugera ku rumuri rw'icyuma; imiyoboro itari iy'icyuma igomba gukuraho umwanda wo hejuru).
   • Niba ubuso bw'umuyoboro budahuje, shyiramo ikintu cyihariye gihuza (nka silica gel, glycerin) kugira ngo wuzuze icyuho kandi uvanemo umwuka (umwuka uzagabanya cyane imiraba y'urusaku). Ikintu gihuza kigomba kuba gihuye n'icyo kintu gikoreshwa (kitangiza umuyoboro).
2. Uburyo bwo Gutunganya Sensor
   • Koresha icyuma cyihariye kugira ngo ushyireho sensor ku muyoboro kugira ngo wirinde gucika intege (gucika intege bizatera kudahagarara neza kw'ikimenyetso), ariko witondere imbaraga kugira ngo wirinde ko umuyoboro wangirika cyangwa kwangirika kw'icyuma.
   • Ku miyoboro yoroshye kwangirika nk'iya pulasitiki, imbaraga z'imiyoboro zigomba kuba ziringaniye kugira ngo hirindwe ko umuyoboro upfunyikwa neza kandi bigahindura imiterere y'amazi.
3. Guhuza no kurinda insinga
   • Insinga zipima umuriro zigomba kugenzurwa kure y’imiyoboro ifite ingufu nyinshi kugira ngo hirindwe ko ibimenyetso bibangamirana, kandi uburebure bw’insinga bugomba kuba bwujuje ibisabwa mu gitabo (insinga ndende cyane zishobora gutuma ibimenyetso bigabanuka).
   • Kugira ngo insinga zishyirwe hanze, ni ngombwa kuzirinda amazi kuzishyira ku nsinga (nk'uko zishyirwa ku nsinga zidashobora kuziba) no kuzirinda izuba kugira ngo hirindwe gusaza kw'insinga.

IV. Guhindura ibidukikije n'imiterere y'akazi

1. Ubushyuhe n'ubushuhe mu kirere
   • Ubushyuhe bw'ikirere bukoreshwa muri sensor bugomba kuba buri mu rugero rwemewe rw'ibikoresho (ubusanzwe -30℃ ~ + 60℃). Irinde ko wahura n'ubushyuhe bwinshi cyane, ubushyuhe buke, cyangwa ahantu hafite ubushuhe bwinshi (shyiramo ibikoresho bikingira ubushyuhe cyangwa ibikoresho bikingira izuba niba bibaye ngombwa).
   • Niba ubushyuhe bw'umuyoboro w'amazi ari hejuru cyane (nk'ubushyuhe burenze 100°C), menya neza ko sensor idashobora guhangana n'ubushyuhe bwinshi kugira ngo wirinde ko igikoresho gihuza ibintu kinanirwa cyangwa ngo cyangirike bitewe n'ubushyuhe bwinshi.
2. Ibisabwa kugira ngo habeho ibimenyetso by'ibisasu n'uburyo birindwa
   • Mu gihe ushyiramo ibikoresho bishobora gushya cyangwa guturika (nk'aho ukorera ibikoresho bya shimi), hitamo ibikoresho bipima ibisasu bihuye n'ibisabwa mu rwego rwo kwirinda guturika.
   • Ku bidukikije byo hanze cyangwa ahantu hashyushye, menya neza ko urwego rwo kurinda ibikoresho ari ≥ IP65 kugira ngo hirindwe ko amazi y'imvura n'umukungugu byinjira.

V. Gutanga no kugenzura nyuma yo gushyiraho

1. Gupima Imbaraga z'Ibimenyetso
   • Nyuma yo gushyiraho, genzura imbaraga z'ikimenyetso unyuze muri flowmeter host (ubusanzwe igaragazwa nk'ijanisha cyangwa decibel). Menya neza ko ikimenyetso gihamye (byaba byiza ≥ 60%). Niba ikimenyetso kidakomeye, hindura aho sensor iherereye cyangwa igikoresho gihuza.
   • Reba niba urujya n'uruza rw'amazi ruhita ruhura n'imiterere nyayo y'akazi (igenzura rishobora gukorwa ugereranije n'agaciro k'urujya n'uruza kazwi cyangwa agaciro k'ubuhanga).
2. Igenzura ry'igihe kirekire ry'ubudahangarwa
   • Reba buri gihe uko sensor ihagaze n'uko igikoresho gihuza (cyaba cyumye cyangwa gitandukanye), cyane cyane mu bihe birimo guhindagura gukomeye cyangwa impinduka z'ubushyuhe.
