Dab tsi yog Qhov Twg Ntawm Ib Lub Pem Hauv Pem Hauv Ntej Block?

Hav nyob ntawd! Raws li tus neeg muag khoom ntawm cov khoom hauv ncoo, kuv feem ntau tau nug txog qhov nruj ntawm cov khoom no. Yog li, cia peb dhia dej mus rau hauv nws thiab rhuav tshem qhov nyuaj ntawm lub hauv ncoo thaiv qhov tseeb txhais tau li cas.

Kev nruj, hauv cov ntsiab lus yooj yim, yog lub peev xwm ntawm cov khoom siv lossis cov qauv los tiv thaiv deformation thaum lub zog siv rau nws. Rau cov khoom hauv ncoo thaiv, qhov no txhais tau tias nws tuaj yeem tswj tau nws cov duab thiab txoj hauj lwm hauv qab load. Ib lub tog hauv ncoo khov kho yuav muaj kev cuam tshuam tsawg dua los yog khoov thaum lub zog tawm ntawm nws.

Qhov tseeb:

Hauv ntau daim ntawv thov, xws li tshuab thiab khoom siv, kev sib raug zoo yog qhov tseem ceeb. Lub tog hauv ncoo khov kho pab tswj txoj haujlwm kom raug ntawm lub ncej, ua kom muaj kev ua haujlwm zoo thiab txo qis hnav thiab tsim kua muag ntawm lwm cov khoom.

Load Capacity:

Ib lub hauv ncoo khov kho tuaj yeem ua haujlwm ntau dua yam tsis muaj deforming. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv hnyav- cov ntawv thov kev ua haujlwm uas muaj cov rog loj.

Kev vibration Damping:

Kev nruj kuj tseem tuaj yeem pab ua kom muaj kev vibrations, uas tuaj yeem txhim kho tag nrho cov kev ua tau zoo thiab lub neej ntev ntawm cov khoom siv.

Khoom siv:

Cov khoom siv los ua lub hauv ncoo thaiv muaj qhov cuam tshuam loj rau nws qhov tawv nqaij. Piv txwv li, cam khwb cia hlau thiab hlau yog feem ntau siv cov ntaub ntawv vim lawv siab tawv thiab lub zog.

Tsim:

Kev tsim ntawm lub hauv ncoo thaiv, nrog rau nws cov duab thiab qhov ntev, tuaj yeem cuam tshuam rau nws qhov tawv nqaij. Ib lub qhov dej-tsim hauv ncoo thaiv yuav faib cov khoom sib npaug, txo qhov kev ntxhov siab thiab txhim kho kev nruj tag nrho.

Mounting:

Kev txhim kho kom zoo yog qhov tseem ceeb rau kev ua kom qhov nruj ntawm lub hauv ncoo thaiv. Yog hais tias lub hauv ncoo thaiv tsis tau mounted kom raug, nws tuaj yeem ua rau cov khoom tsis sib xws thiab txo qis.

Muaj ntau txoj hauv kev los ntsuas qhov nruj ntawm cov khoom hauv ncoo blocks. Ib txoj hauv kev yog siv lub xov tooj ntawm tes los siv lub zog paub rau lub hauv ncoo thaiv thiab ntsuas qhov tshwm sim deflection. Qhov tawv nqaij tuaj yeem suav nrog siv cov mis:
Nyuaj=Force / Deflection

Lwm txoj hauv kev yog siv lub ntsuas ntsuas ntsuas los ntsuas qhov strain hauv lub hauv ncoo thaiv hauv qab load. Qhov tawv nqaij tuaj yeem suav nrog kev sib raug zoo ntawm kev ntxhov siab thiab kev nyuaj siab.

Raws li tus neeg muag khoom, peb muab ntau yam ntawm cov khoom hauv ncoo blocks nrog ntau qib sib txawv kom ua tau raws li qhov xav tau ntawm ntau yam kev siv. Peb cov khoom yog tsim los ntawm siab - cov ntaub ntawv zoo thiab tsim los muab kev ua tau zoo thiab kev ntseeg siab.

Peb kuj muab Take Up Bearing Unit, uas yog tsim los kho qhov nro nyob rau hauv ib tug siv los yog saw tsav. Cov chav no muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab kev teeb tsa kom haum rau kev siv sib txawv.

Tsis tas li ntawd, peb muab Zinc Alloy Bearing Units KFL000, uas yog tsim los ntawm siab - zinc alloy zoo thiab yog tsim los muab kev tiv thaiv corrosion zoo thiab kav ntev. Cov chav no zoo tagnrho rau siv nyob rau hauv ib puag ncig hnyav.

Thaum kawg, peb muab Ductile Iron Housing And Units, uas yog tsim los ntawm cov hlau nplaum thiab tsim los ua kom muaj zog thiab nruj. Cov chav no yog qhov zoo tagnrho rau siv hauv cov ntawv siv hnyav -.

Qhov nruj ntawm lub hauv ncoo thaiv yog qhov tseem ceeb uas yuav tsum tau xav txog thaum xaiv lub hauv ncoo thaiv rau koj daim ntawv thov. Lub hauv ncoo khov kho tuaj yeem muab qhov tseeb zoo dua, muaj peev xwm thauj khoom ntau dua, thiab txhim kho kev co damping. Ntawm peb lub tuam txhab, peb muab ntau yam ntawm cov khoom hauv ncoo blocks nrog ntau qib sib txawv kom ua tau raws li qhov xav tau ntawm ntau yam kev siv. Yog tias koj muaj lus nug lossis xav tau kev pab xaiv lub hauv ncoo zoo rau koj daim ntawv thov, thov tsis txhob yig tiv tauj peb. Peb nyob ntawm no los pab koj nrhiav kev daws teeb meem zoo tshaj plaws rau koj cov kev xav tau.
