Tusaale dhibaaca koronto iyo khaladka mojaraadka adhigalka wixii koronto adhigalka

Tahlilka tiroleynta xanuun wuxuu caawiya in lagaga fahmo dhaawacyada mekanikaal ee aan caadiga ahayn oo ku jira in kala soo kooban tahay. Iimahaannada waxay u isticmaalaan badanaan qalabta FFT ka saaran oo la wadaag accelerometers si ay ugu diwaan gelin dhawaafinta xanuun marka hantida horumarineed ay yihiin. Marka laabeedku yaraan, waxay muuqdaa sida noocaha sanas leh ee sare. Khasaraha midabka muujinaya xanuunka weyn si waawayn marka la eego kiisaska asalka iyo laba kiis, gaar ahaan marka loo eego qaabka laabka oo khasaraha wareegga kala duwan. Tijaabada dhexdooda muujinaya in khasaraha wareegga kala duwan waxay abuuraan xanuun xooggan kala duwan 30% ka badan khasaraha kale. Waxa magacmuujiyaha teknikadu waa in uu sharaxa si wanaagsan laabeedka in la isticmaal ama khasaraha midabka oo kaliya in la iskudhuudo iyaga iyadoo loo isticmaalayo qalabta laaser. Masrifihii oo walba ay isku dayi doonaan in ay iskudhexaysaan dhawaafinta xanuun kila sanadna saddex jeer waxay arkaan hoos u dhaca 41% oo kala duwan in la soo kooban tahay sidii u sharxatay warbixintii dambe ee 2023 ee Warbixin Xafiiska Masruufaha.

Sida 62% ee muhiimadda ku jiraan xaaladaha dhaawaca, laguma tasho qaybta motoor-ka lama hubin, laakiin keliya qaybta hoos u dhacday

Sida ku xusan karta arrimaha maamulka, khaladka ku qoran motoorka waa sabab u ah si toos ah 62% ee dhammaan arimaha korontooyinka dhulka lagu guda jiro mid walba, ma aha aagga la soo saaray sida ay badan u fikiriyeen. Khaldan waxaa noqonaa sababihiin kama ama furitaanka jirka, dhulka ka socota, ama midnana laga soo celin karo si khalad mar kale ka dib markii lagu wadaago maashinkan. Waxa ka beddelkooda khaldan ka dib loo yaqaan in kharash weyn yahay midnane ah, taas oo leh hogaamiyaha kharashka ah oo korontooyinka dhowrka ah. Arimaha korontooyinka badanaa waxay muujinayaan sida sameeynta markii khorodhka bilaabeen inay ka qalifaan, taas oo abaalmarin kara badan. Sidaas daraaddeed waa sababta inti badan oo dadka inay beddesho khorodhka iyadoo aaminsan inay cusbooneesiyaan, laakiin korontooyinkan sameeysaa mid kale si toos ah. Haddii dhukaankan focus ku yeelan tahay inay arkayeen khaladka laser markii maamulka caadiga ah, waxayna ku haysteen sababta kooban ee arimaha. Qolkaas waxay iskudhufanaysaa in maashinkan isku daydo dheer iyo inay kalsooni ku samaysataan awoodda korontooyinka diamond polishing pads.

Qiimayn khaaskada drive plate iyo staabilkii dabinka hoos jira load ayaad u gudbaysaan

Xeeldharka haabka shaqada ee drive plates ee ku jira haashada shaqada waxay kaa caawinaysaa in lagu helo arrimo xanuunsiis oo kama arko. Ku qalabi grinder-ka laakiin marka hore ha idhiin dhulka si aynu u arko habaafka uu ku xanuunsiinayo. Tanaaska xanuunsiinta badanaa waxay tuulaysaa in mid ah ay ka soo dhacday spindle-ka ama in ay ka soo dhacday qabaabka uu ku qaba drive plate-ka. Uguma waana inaad ku wareejiso qaylo yar oo aad ku wareejiso maashinka marka aad ku fiirsato meelaha ay ku dhowaadaan. Haddii ay ku xanuunsiinayo midabka, waxay noqon karaan in bushings-ka ay ka sii kala duwan tahay ama in ay ka soo dhacday motor coupling-ka. Iyada hada Equipment Maintenance Quarterly, haddii drive plates-ka ay ka sii 0.5 mm runout, waxay si fiican ku xanuunsiin karaan sida 70%. Marka hore inaad kala toosid, fiiri in dhammaan ugaasaha ay ka dhab yar, sababtoo ah in kala duwanaansho ay ka dhici karaan xanuunsiinta aan rabnayn.

Ku daridda badhanka anti-vibration (anti-dhagaysiga) kuwaas ayaa caawiya in lagu yaruro dhagaysiga sababtoo ah inay dhex marqaato nidaamka damping (dhex dhagaysiga). Sidaas darteed, waa inaad fiirsato saafalka hoose si aad u ogaato in jirto furan, kariin ama goobo qalabnimo oo laga yaabaa inay sii kala socon doonto. Dhulkii marka la boogdo ayaa soo bixi kalin hadii jirto goobta furiyey ka horteed. Dareeminta mashaqulka ma u dhigi karaan in dhagaysigu aad u fudud tahay, laakiin sidoo kale waxay ilaali doontaa in badhankii dmaynta ha uusan la glaze-yno (la cabsado), waxaana heli karta natiijo gaar ah oo gaar ah. Badankooda waxbarashada waxay leedahay in saddexanba midkooda ee shakaydharka dhagaysiga ay ka timaadaan saafalka adag, kuma saadaalo baahintu iyadoo mid ah naadharka.

Qeybta Faq

Maxay sababaya in lafaha grinder-ka ay ka duwan yihiin?

Khalinta mekaaniskaaliga komponennta gurigga ayaa lagu xidhi maydhnimo sida khalinta rotoorka, khalinta xagga shindhaafka, budhnaanshaha baranishkii, iyo khalinta xagga moorka.

Sida aad u kordhibtid dhaawacaanka guriggii dhufashada?

Si aad u kordhibtid dhaawacaanka, hubti in rotoorka iyo xagga shindhaafka waxay tahay si toos ah, ka fiiri falka saajinaha diyaamand ee murmurka iyo saafidhka dhaqaadhka, beddel deeyadda shaqada, isku day in la xaqiijiyaa dhaawacaanka dhufashada iyadoo isticmaalaya buuyinkii joojinta iyo ka fiirin dhulka hoose.

Sida lagu maamulo tallaabooyinka dhaawacaanka gurigga?

Tallaabooyinka dhaawacaanka la maamulaa isticmaalaya qiimaynada taliyada qoraxda (dial indicator) si loo qoree khalinta rotoorka iyo jerada shindhaafka, tijaabada spektramta dhaawacaanka, iyo ka fiirin falka saajinaha diyaamand ee murmurka iyo saafidhka dhaqaadhka.

Maxaad leedahay in khalinta xagga moorka ay ku daran tahay tallaabooyinka dhaawacaanka gurigga?

Khalinta xagga moorka ayaa ku daran tahay tallaabooyinka dhaawacaanka maxaa yeelay waxay abuuraan dabbaarro weyn oo dhacdo lambar, oo abuura xooggaga noqon karta inay dhammaystariyaan dhaawacaanka badan oo badanaa lacag la dhigaa inay tahay budhnaanshaha baranishka.
