Summary: Allon rawar jiki na'ura ce mai mahimmanci a cikin matsi, wanda ke taka rawa wajen tacewa da kuma tantance granites. Masu amfani na iya sarrafa ƙimar tacewa ta hanyar daidaita yawan motsin allon rawar jiki. To, ta yaya za mu daidaita ƙimar motsin allon rawar jiki? Kuma menene ya jawo shi?...
Na'urar Fara-Bincike Na'urar da ba za a iya maye gurbinta ba a tafasa, wacce ke taka rawar bincike da kuma gano kayan gina gini. Masu amfani za su iya sarrafa saurin bincike ta hanyar daidaita ƙarfin jikin da ke rawa. To, ta yaya za mu daidaita ƙarfin rawa? Kuma menene dalilin hakan?
A's gasu, dalilan da suka fi muhimmanci ga ƙananan ƙarfin allo mai rawa sune wadannan:
1. Tashin karfin wutar lantarki ba isa ba
Misali, an tsara allo mai rawa bisa karfin lantarki na 380V na-hujja uku, idan layin ba a haɗa shi kamar yadda aka bukata ba; idan karfin lantarki bai isa ba, hakan zai sa allon rawa ya yi ƙarancin ƙarfi.
2. Kananin abubuwan da suka karkace
Ta hanyar ƙara ko rage yawan ƙananan blocks na eccentric, zaka iya sarrafa ƙimar motsin zagayawa na allo mai rawa. Idan kana son ƙara yawan motsin zagayawa, zaka iya ƙara yawan blocks na eccentric.
3. Kusurwar da ke tsakanin abubuwan da suka karkace ba ta isa ba
Idan allurar allo mai jijjiga yana da motar jirgi mai jijjiga, kusurwar tsakanin ƙwayoyin eccentric a duk ƙafafun shaft na motar zai shafi ƙarfi mai ƙarfi. Matsanar kusurwa kadan ne, ƙarfafa ƙarfi zai ƙaru, kuma yawan jijjiga zai ƙaru. Saboda haka, masu amfani za su iya daidaita yawan jijjiga ta hanyar canza kusurwar.
4. Ƙara abinci mai yawa yana haifar da taruwa mai yawa
Idan dutse da aka tura zuwa saman allon ya wuce ƙarfin ɗaukar sa a lokaci guda, za a tara kayan a cikin gilashin allo. Wannan zai ƙara ɗaukar kayan na kayan aikin kuma zai shafi girman motsi. Idan haka, dole ne a daina injin ɗin da farko, a rage kayan a allon zuwa cikin al'ada, sannan a kunna. Bugu da ƙari, ƙananan kwayoyin kayan suna da dangantaka kai tsaye da girman motsin allon na girgiza.
5. Tsare-tsaren bazuwar ba dacewa ba
As we all know, vibrating screen is mainly composed of vibrator, screen box, supporting device, transmission device, etc. As an important part of supporting device, spring should be designed precisely. The net variable of the spring should be less than the height of the device, or it will cause small amplitude. What’s more? The net variable of the spring cannot be too large, or it will separate from the body.
6. Lalacewar Kayan Aiki
1) An lalata motar ko abubuwan lantarki
Da farko, dole ne mai amfani ya duba motar, idan ta lalace, ya kamata a maye gurbin ta cikin lokaci. Na biyu, duba bangaren wutar lantarki a cikin sarrafa, idan ta lalace, don Allah a maye gurbinta.
2) Lalacewar mai rawa
Duba yawan man shafawa a cikin masu motsa jiki, kara man shafawa da ya dace cikin lokaci, duba ko masu motsa jiki suna da matsala, kuma gyara ko maye gurbinsu cikin lokaci.
Wani abu da za a lura da shi shine cewa a yayin da ake daidaita girman kararrawar duban matsi na vibrating screen, ko dai ta hanyar ƙara nauyin jikin eccentric, daidaita kusurwar eccentric blocks, ko ƙara ko rage nauyin akwat ɗin juyawa da *pulley* (ántar da vibration mai motsi kusa da axis), dole ne a daidaita ƙimar na'urar vibration (vibrator ko crank vibration motor) daidai; in ba haka ba, zai sanya kayan aiki ya lalace.
