Girman jagorarbawuloli na toshe shaftGalibi ƙanƙanta ne, kuma daidaiton dukkan bawuloli gabaɗaya yana da girma, daga 0.4 zuwa 1 mm, wanda ke da amfani wajen samar da girgizar injiniya. Saboda haka, lokacin da aka sami ƙaramin girgizar injiniya, girgizar za ta iya raunana ta hanyar ƙara girman jagora da rage gibin da ya dace.

4. Canza siffar maƙurar don kawar da sautin

Saboda abin da ake kira tushen girgiza nabawul mai daidaitawayana faruwa a tashar maƙura inda kwararar ruwa mai sauri da matsi ke canzawa da sauri, canza siffar maƙura na iya canza mitar tushen girgiza, wanda ya fi sauƙi a warware shi idan sautin bai yi ƙarfi ba.

Hanyar da aka saba amfani da ita ita ce a juya saman lanƙwasa na tsakiyar bawul ɗin da 0.5 ~ 1.0mm a cikin kewayon buɗewar girgiza. Misali,bawul mai sarrafa matsin lamba mai sarrafa kansaan sanya shi kusa da yankin iyali na masana'anta. Sautin busa da resonance ke haifarwa yana shafar sauran ma'aikata. Bayan an juya saman tsakiyar bawul da 0.5mm, sautin busar resonance zai ɓace.

5. Sauya ɓangaren matsewa don kawar da sautin

Hanyoyin sune:

Canza halayen kwarara, logarithmic zuwa layi, layi zuwa logarithmic;

Sauya siffar tsakiyar bawul. Misali, canza nau'in toshe shaft zuwa tsakiyar bawul mai siffar "V", sannan a canza nau'in toshe shaft na bawul mai kujera biyu zuwa nau'in riga;

Canza hannun riga na taga zuwa hannun riga mai ƙananan ramuka, da sauransu.

Misali, bawul ɗin DN25 mai kujeru biyu a cikin masana'antar takin nitrogen sau da yawa yana girgiza kuma yana karyewa a lokacin da aka haɗa tsakanin tushen bawul da zuciyar bawul. Bayan mun tabbatar da cewa yana da ƙarfi, mun canza tsakiyar bawul ɗin siffa mai layi zuwa tsakiyar bawul ɗin logarithmic, kuma an warware matsalar. Wani misali kuma shine bawul ɗin hannun DN200 da ake amfani da shi a dakin gwaje-gwaje na kwalejin jiragen sama. Filogin bawul ɗin ya juya sosai kuma ba za a iya amfani da shi ba. Bayan canza hannun da taga ta yi zuwa hannun riga mai ƙaramin rami, juyawar ta ɓace nan take.

6. Canza nau'in bawul ɗin sarrafawa don kawar da resonance

Mitar bawuloli masu tsari daban-daban ta halitta ta bambanta da ta halitta. Canza nau'in bawuloli masu tsari ita ce hanya mafi inganci don kawar da sautin murya.

Rawar bawul tana da matuƙar tsanani yayin amfani da ita - tana girgiza sosai (a cikin mawuyacin hali, ana iya lalata bawul ɗin), tana juyawa sosai (har ma da bawul ɗin yana girgiza ko murɗewa), kuma tana haifar da ƙara mai ƙarfi (har zuwa fiye da decibels 100). Kawai maye gurbin bawul ɗin da bawul mai babban bambancin tsari, kuma tasirin zai kasance nan take, kuma ƙarfin radar zai ɓace ta hanyar mu'ujiza.

Misali, an zaɓi bawul ɗin hannun riga na DN200 don sabon aikin faɗaɗawa na masana'antar vinyl. Abubuwan da ke sama guda uku suna wanzuwa. Bututun DN300 yana tsalle, toshewar bawul yana juyawa, hayaniyar ta fi decibels 100, kuma buɗewar amsawar ta fi 20 zuwa 70%. Yi la'akari da buɗewar amsawar. Matakin yana da girma. Bayan amfani da bawul mai kujeru biyu, amsawar ta ɓace kuma aikin ya kasance na yau da kullun.

7. Hanyar rage girgizar cavitation

Saboda girgizar cavitation da rugujewar kumfa na cavitation ke haifarwa, abu ne na halitta a nemo hanyoyin rage cavitation.

Ƙarfin tasirin da fashewar kumfa ke samarwa ba ya aiki a kan saman da ya yi ƙarfi, musamman tsakiyar bawul, amma ruwan yana sha. Bawul ɗin hannun riga suna da wannan fasalin, don haka ana iya canza tsakiyar bawul ɗin shaft zuwa nau'in hannun riga.

A ɗauki dukkan matakai don rage cavitation, kamar ƙara juriyar matsewa, ƙara matsin lamba na matsewa, rage matsin lamba a jere ko a jere, da sauransu.

8. Guji hanyar kai hari kan tushen girgiza

Girgizar raƙuman ruwa daga tushen girgizar waje yana haifar da girgizar bawul, wanda a bayyane yake wani abu ne da ya kamata a guji yayin aiki na yau da kullun na bawul ɗin da ke daidaita shi. Idan irin wannan girgizar ta faru, ya kamata a ɗauki matakan da suka dace.
