Tus nqi ntawm ob - hais lus handwheel tsis zoo li qub; los ntawm kev nkag siab zoo ntawm cov khoom no, ib tus tuaj yeem txheeb xyuas qhov tseem ceeb uas cuam tshuam rau nws cov nqi. Hais lus dav dav, yam cuam tshuam rau tus nqi ntawm cov khoom no tuaj yeem faib ua cov hauv qab no:
1. Cov khoom sib txawv ua rau cov nqi sib txawv.
Nws yog ib txwm ua rau cov khoom tsim los ntawm cov ntaub ntawv sib txawv los tswj cov nqi sib txawv. Feem ntau hais lus, cov ntaub ntawv hlau yog kim kim dua li cov ntaub ntawv yas. Cov kev xaiv hlau muaj xws li stainless hlau, txheem hlau, txhuas alloy, thiab zinc alloy, thaum xaiv yas xws li Bakelite, nylon, PP, thiab ABS.
Txawm nyob rau hauv qeb ntawm cov ntaub ntawv hlau, cov kev xaiv tshwj xeeb-txawm yog stainless hlau, txheem steel, aluminium alloy, los yog zinc alloy- ua rau cov ntsiab lus sib txawv; zoo sib xws, cov nqi sib txawv txawm ntawm ntau hom khoom yas. Tsis tas li ntawd, cov khoom sib txawv muaj cov yam ntxwv ntawm kev ua tau zoo.
2. Cov txheej txheem tsim khoom sib txawv ua rau muaj qhov sib txawv ntawm tus nqi.
Lub sophistication thiab kev loj hlob ntawm cov txheej txheem tsim khoom ncaj qha cuam tshuam nrog qhov zoo ntawm cov khoom kawg. Thaum ua kev yuav khoom, cov neeg siv khoom yuav tsum txiav txim siab cov khoom tsim nyog raws li qhov xav tau ntawm lawv qhov chaw ua haujlwm tiag tiag -piv txwv li, txawm tias ib puag ncig cuam tshuam rau cov kua qaub, alkalis, lossis tshuaj reagents; seb nws yog av; seb puas muaj cov cai tshwj xeeb txog kev zoo nkauj ntawm qhov chaw; los yog seb qhov kev xav zoo tactile yog qhov tseem ceeb.
3. Geographical Location cuam tshuam tus nqi.
Vim qhov tsis sib xws hauv cheeb tsam hauv kev txhim kho kev lag luam, qib kev noj haus sib txawv ntawm thaj chaw sib txawv. Feem ntau, kev lag luam ntawm thaj chaw ntug dej hiav txwv sab hnub tuaj yog tsim ntau dua li cov cheeb tsam hauv av; yog li ntawd, cov khoom lag luam tus nqi hauv cov ntug dej hiav txwv no zoo li siab dua.
Txoj kev xa khoom rau cov khoom siv raw thiab cov nqi ua haujlwm kuj sib txawv raws thaj tsam, yam uas cuam tshuam ncaj qha rau tus nqi kawg ntawm cov khoom. Tsis tas li ntawd, cov khoom lag luam txawv teb feem ntau nqa tus nqi siab dua li cov khoom tsim hauv tsev.
4. Qhov txawv ntawm cov txheej txheem ntws cuam tshuam rau tus nqi.
Cov txheej txheem tsim khoom ntws ncaj qha cuam tshuam cov khoom zoo. Yog tias cov chaw tsim khoom tseem ceeb thiab ua tib zoo ua cov txheej txheem ntws, cov khoom tsim tawm yuav ua kom zoo nkauj, ua kom zoo nkauj thiab ua kom pom tseeb. Hloov pauv, yog tias cov chaw tsim khoom koom nrog kev ua haujlwm tsis zoo, cov khoom lag luam yuav tsis muaj qhov tseeb, muaj qhov ntxhib ntxhib, thiab muaj lub neej ua haujlwm luv dua.
Muab ob npaug rau- hais lus handwheels tuav ib qho kev lag luam tseem ceeb thoob plaws ntau qhov kev lag luam. Lawv tau siv dav hauv ntau daim ntawv thov, suav nrog cov cuab yeej siv tshuab, ntim tshuab, khoom siv ua zaub mov, vuam apparatus, thiab textile machinery. Lawv kev koom ua ke tso cai rau kev ua haujlwm tsis muaj zog ntawm cov cuab yeej siv, yog li txo qhov kev tawm dag zog lub cev xav tau ntawm cov neeg ua haujlwm tshuab. Tus nqi lag luam ntawm cov khoom no yog ib qho teeb meem tseem ceeb rau cov neeg siv khoom; Tseeb tiag, ntau tus neeg yuav khoom tsuas yog tsom rau tus nqi xwb-txawm siab lossis qis-thaum tsis quav ntsej lwm yam tseem ceeb xws li cov khoom lag luam npaj ua haujlwm, thauj khoom- cov kabmob muaj peev xwm, kev ua haujlwm zoo, thiab kev pabcuam lub neej. Txoj hauv kev no tuaj yeem yooj yim ua rau kom tau txais cov khoom lag luam uas ua tsis tau raws li qhov xav tau ntawm kev ua haujlwm tiag tiag.
Thaum xaiv cov khoom no, cov neeg siv yuav tsum tau txais kev pom zoo es tsis yog kho tshwj xeeb ntawm tus nqi rau kev tsis saib xyuas lwm yam; Nws yog ib qho tseem ceeb heev uas yuav tau xaiv raws li qhov tshwj xeeb, tiag tiag - lub ntiaj teb cov xwm txheej raws li cov khoom yuav raug siv. Ib tug yuav tsum tsis txhob cuam tshuam rau cov khoom zoo, kev ua tau zoo, lossis kev zoo nkauj tsuas yog txuag ob peb xees lossis nyiaj daus las.
Tus nqi ntawm ob - hais lus handwheel hloov pauv hauv cov lus teb rau kev hloov pauv hauv kev lag luam. Yog tias koj xav tau cov ntaub ntawv tus nqi tam sim no rau cov khoom no, peb xav kom hu rau tus neeg muag khoom, leej twg yuav tsum tuaj yeem muab cov ntaub ntawv raug thiab nce rau koj - mus rau - hnub cov ntsiab lus ntawm tus nqi.
