** Ceeb Toom Tseem Ceeb:** Qhov no yog cov ntawv sau keeb kwm, tsis yog lub tshuab tam sim no, kev suav muaj peev xwm, kev ntsuas kev pheej hmoo lossis phau ntawv khiav haujlwm. Tightening txoj kev, qauv, qhov ntev, ceev, qauv, testers thiab cov txheej txheem yuav tsum tau soj ntsuam raws li cov kev cai siv, chaw tsim tshuaj paus cov ntaub ntawv thiab kev nyab xeeb txoj kev ua hauj lwm.

Cov ntawv no tsis yog kev muab cov tshuab, cov neeg sim lossis cov ntaub ntawv pabcuam ntawm Savo Kusić. Qhov kev thov tam sim no yog tsom rau qhov rais, qhov rooj thiab cov kev daws teeb meem cuam tshuam.

Tightening the saw in the frame

Nrog gutters, cov saws yuav tsum zoo ruaj ntseg thiab tensioned nyob rau hauv tus ncej. Thaum ua hauj lwm nrog weakly tensioned saws, ib tug shard nyob rau hauv daim ntawv ntawm ib tug wavy txiav, thiab lwm yam. Txoj kev nruj tshaj plaws ntawm kev zawm lub saw yog los ntawm txoj hlua khi, eccentric, ntsia hlau (Daim duab1), nrog rau txoj kev nruj siv cov khoom siv hydraulic. Tightening saw nrog wedges yog phem dua li lwm txoj kev. Ib tug loj tus naj npawb ntawm industries tsim ib tug loj tus naj npawb ntawm hom muaj zog, ceev-tsav, ua tau zoo heev saws. Cov sawmills uas muaj txiaj ntsig zoo no ua haujlwm hauv cov ntoo ua ntoo loj hauv kev tsim kho kev lag luam. Cov yam ntxwv ntawm cov gaiters no tau muab rau hauv lub rooj1.

Gator productivity yog xam raws li tus qauv: P = K - Δtnq/1000L m3. Qhov twg K yog tus gater siv coefficient. Rau cov tshuab dhos tshuab K = 0.93, thiab rau cov tshuab ib nrab K = 0.90;  Δ - hloov mus rau ib qho tig ntawm lub rooj vag ncej; n - tus naj npawb ntawm cov kiv puag ncig ntawm lub qhov rooj ncej ib feeb; t - khaws lub sijhawm ua haujlwm hauv feeb; q - log ntim, m3; L - ntev ntawm cov cav, m.

Kev suav keeb kwm ntawm kev tsim khoom

Thaum txiav txim siab qhov nruab nrab txhua xyoo kev tsim khoom ntawm lub gater rau ib qho kev ua haujlwm, kev nres, uas tshwm sim vim muaj ntau yam ua rau (kev kho, tsis muaj cov khoom siv raw, thiab lwm yam) yuav tsum raug coj mus rau hauv tus account. Cov kev poob no yog txiav txim los ntawm kev sim coefficient Kgod = 0.9 - 0.92.

Yog li ntawd, qhov nruab nrab txhua xyoo kev tsim khoom ntawm tus neeg saib xyuas qhov rooj rau ib qho kev hloov pauv yog txiav txim los ntawm cov qauv P = Kgod x K x Δntq/1000L m3 rau ib qho kev hloov.

Technical yam ntxwv ntawm gater saws yog muab rau hauv lub rooj 3.

Saws yog ua nyob rau hauv ob txoj kev hniav: nrog ib tug tawg rov qab ntug thiab nrog ib tug ncaj rov qab ntug (daim duab.2). Thaum xaiv qhov xav tau qhov ntev ntawm lub saw, koj yuav tsum tau coj los ntawm qhov ntev ntawm lub thav duab ntawm lub qhov rooj, qhov loj ntawm nws cov hlab ntsha thiab txoj kab uas hla ntawm cov cav yuav raug txiav. Qhov ntev ntawm cov saw tuaj yeem txiav txim siab los ntawm cov mis L = Dmax + H + (300rau350) mm, qhov L yog qhov ntev ntawm lub saw, mm; Dmax - qhov siab tshaj plaws ntawm cov cav yuav raug txiav;300-350- nyiaj pub vim kev teeb tsa ntawm cov ntawv ntxig rau cov laug cam thiab battens; H - stroke qhov siab, mm.

Cov saws raug ntsia ua ke nrog stirrups uas txuas mus rau qis kawg ntawm lub saw thiab nrog ib txheej ntawm ob stirrups thiab xya bolts rau sab sauv kawg. Cov stirrups yog txuas rau lub saw ntawm txoj cai kaum rau nws sab nraub qaum. Lub beveled ntug ntawm lub stirrup yuav tsum tig mus rau ib leeg. Ua ntej riveting lub stirrup, cov npoo ntawm cov saw yuav tsum tau kuaj xyuas seb lawv puas ncaj thiab sib npaug, thiab yog tias lawv tsis yog, lawv yuav tsum tau muab txiav rau ntawm lub tshuab saw sharpening.
