Midziyo yekutanga yematirakita ekumaruwa uye mota dzekutakura dzekurima dzakashongedzerwa nemhepo mafirita, mafirita emafuta uye mafirita edhiziri, anowanzozivikanwa se "mafirita matatu". Kushanda kwe "mafirita matatu" kunobata zvakananga basa rekushanda uye hupenyu hwebasa remutangi. Parizvino, vatyairi vazhinji vanotadza kuchengetedza uye kuchengetedza "mafirita matatu" zvichienderana nenguva yakatarwa uye mitemo, zvichikonzera kutadza kweinjini nguva nenguva uye kupinda nguva isati yakwana munguva yekugadzirisa. Ngatizvitarisei zvinotevera.
Iyo tenzi yekuchengetedza inokuyeuchidza: kuchengetedza uye kuchengetedza kwemhepo sefa, mukuwedzera kune yakajairwa uye kushanda uye kugadzirisa zvinodiwa, inofanirwawo kuterera kune anotevera mapoinzi:
1. Iyo inotungamira grille yemhepo sefa haifanirwe kukanganiswa kana marara, uye iyo inclination angle inofanira kuva 30-45 degrees. Kana kushorwa kuri kudiki, kunowedzera uye kunokanganisa kuyerera kwemhepo. Kana mhepo yemhepo yakanyanyisa, kutenderera kwemhepo kunopera uye kuparadzaniswa kubva kuguruva kuchaderedzwa. Nzvimbo dzekunze dzemablades hadzidi kupendwa kuti dzidzivirire oxidation particles kuti isapinda muhumburumbira.
2. Mesh yemhepo inofanira kucheneswa panguva yekugadzirisa. Kana iyo sefa iine guruva kapu, iyo guruva particle urefu haifanire kudarika 1/3, kana zvisina kudaro inofanira kubviswa nenguva; muromo wekombe yeguruva unofanirwa kuvharwa zvakasimba, uye chisimbiso cherabha hachifaniri kukuvadzwa kana kuraswa.
3. Kureba kwechiyero chemafuta chesefa kunofanira kusangana nezvinodiwa. Kana chiyero chemafuta chakanyanya kukwira, chinokonzera kabhoni deposits mucylinder. Oiri yakaderera zvakanyanya inoderedza kushanda kwesefa uye inomhanyisa kupfeka kwayo.
4. Kana iyo mesh yesimbi (wire) mufirita inotsiviwa, dhayamita yegomba kana tambo inogona kungova duku zvishoma, uye simba rekuzadza harigoni kuwedzerwa. Zvikasadaro, kushanda kwesefa kuchaderedzwa.
Ngwarira kudonha kwemhepo yepombi yekupinda, uye kuchinja kwemafuta uye kuchenesa kunofanira kuitwa munzvimbo isina mhepo uye guruva; iyo fan sefa inofanirwa kuitirwa munzvimbo ine hunyoro hunyoro uye yakanyanya kudzvanywa mweya, uye iyo yekufuridza inofanirwa kutarisana nemhepo inopinda musefa skrini; panguva yekuisa, Iwo anopeta mafaera epadyo mafirita eDi anofanira kupinda mukati memumwe nemumwe.
