Nyob rau hauv lub nthwv dej ntawm kev hloov pauv ntse ntawm cov tshuab siv hauv kev tsim kho, lub tshuab hluav taws xob tsav tswj lub qhov rooj tau dhau los ua qhov chaw tseem ceeb ntawm kev lag luam nrog nws qhov chaw ua haujlwm meej, kev hloov pauv dav dav thiab cov yam ntxwv zoo tshaj plaws. Cov khoom siv tshiab no uas koom ua ke kev tswj hwm hluav taws xob thiab kev ua haujlwm kho tshuab muab cov kev daws teeb meem zoo rau kev ua haujlwm engineering hauv qab ntau yam kev ua haujlwm los ntawm kev ua kom zoo dua txhua yam.
Kev muab hluav taws xob ruaj khov kom ntseeg tau tias kev ua haujlwm ntawm cov khoom siv txhim khu kev qha
Hais txog kev muab hluav taws xob, lub qhov tswj hwm no muaj kev hloov pauv zoo heev. Nws qhov hluav taws xob ntau yog 10-32VDC, thiab nws tuaj yeem ua haujlwm ruaj khov hauv ntau qhov chaw muab hluav taws xob, txawm tias nyob rau hauv qhov xwm txheej tsis ruaj khov ntawm kev muab hluav taws xob ib ntus hauv thaj teb lossis hauv cov xwm txheej ib txwm muaj nrog kev teeb tsa hluav taws xob txheem, nws tuaj yeem ua kom cov khoom siv ua haujlwm ib txwm. Tib lub sijhawm, nws cov yam ntxwv siv hluav taws xob tsawg yog qhov zoo heev, tsuas yog 100mA lossis tsawg dua, uas txo cov khoom siv hluav taws xob siv thiab txhim kho kev siv hluav taws xob zoo. Lub zog tam sim no tsuas yog txwv rau 10A lossis tsawg dua, uas zoo tiv thaiv kev puas tsuaj rau cov khoom siv los ntawm kev poob siab tam sim no ntau dhau thiab ua kom muaj kev nyab xeeb thiab ruaj khov ntawm tag nrho lub cev hluav taws xob.
Kev xa xov tooj cua zoo rau kev tswj hwm meej
Qhov teeb liab tso zis yog qhov tseem ceeb ntawm cov khoom no. Siv CAN (SAE J1939) EJM1 kev sib txuas lus raws li txoj cai, qhov chaw nyob yog teem rau 249, tus nqi sib txuas lus yog txog li 250kbps, thiab nrog lub sijhawm kuaj ntawm 10ms, cov lus qhia ua haujlwm tuaj yeem xa mus rau lub kaw lus tswj kev khawb av sai thiab raug. Qhov no tso cai rau txhua qhov kev ua ntawm tus neeg teb xov tooj kom raug xa rov qab rau cov khoom siv raws sijhawm thiab raug, ua tiav qhov tseeb ntawm kev ua haujlwm millimeter. Qhov tseeb ntawm cov zis kuj zoo heev nyob rau hauv ntau qhov chaw kub sib txawv. Hauv ib puag ncig ntawm -10 - +50 ° C, qhov tseeb nruab nrab tuaj yeem ncav cuag ± 2%, thiab hauv ib puag ncig ntawm -40 - +75 ° C, nws kuj tuaj yeem tswj tau ntawm ib puag ncig ± 3%, kom ntseeg tau tias cov khoom siv tuaj yeem ua haujlwm ruaj khov thiab raug hauv ntau qhov chaw nyuaj.
Cov txheej txheem kho tshuab precision, ob qho tib si durability thiab xis nyob
Los ntawm qhov kev xav ntawm cov kev ua haujlwm kho tshuab, lub tes tuav tswj lub qhov (control valve handle) kuj ua haujlwm tau zoo. Nws lub hysteresis raug tswj ntawm ±1.6% lossis tsawg dua, thiab qhov nruab nrab ntawm lub tshuab yog 0.5 ° lossis tsawg dua, uas ua rau lub tes tuav ua haujlwm zoo thiab teb tau zoo, txo qhov yuam kev ua haujlwm thiab txhim kho kev nplij siab thiab qhov tseeb ntawm kev ua haujlwm. Qhov kub ntawm kev pabcuam yog -40-75 ° C, uas tuaj yeem hloov kho rau ntau qhov chaw ib puag ncig hnyav los ntawm thaj chaw txias polar mus rau thaj chaw kub, nthuav dav cov xwm txheej ntawm daim ntawv thov ntawm cov khoom siv. Lub zog ua haujlwm siab tshaj plaws yog 226N / m, uas ua kom ntseeg tau tias lub tes tuav ruaj khov txaus los tiv taus kev siv siab thaum ua kom muaj zog ua haujlwm tsim nyog.
Cov lus qhia hloov pauv ntse, kev ua haujlwm zoo tshaj plaws
Hais txog cov lus qhia ntawm lub qhov hloov, cov khoom no kuj tau tsim ua tib zoo. Lub zog ntsuas thiab tam sim no tau muab faib ua ob qho kev qhia tshwj xeeb: DC30V/3A (resistance load) thiab DC30V/1A (resistance load). Lub peev xwm qiv tsawg kawg nkaus yog DC5V/160mA thiab DC30V/26mA. Lub peev xwm ua haujlwm thiab lub zog ua haujlwm kuj tau teeb tsa raws li cov qhov hloov sib txawv, xws li cov qhov hloov 1 thiab 3 yog 1mm/4N, thiab qhov hloov 2 yog 1mm/6N. Cov kev ntsuas no ua rau kev ua haujlwm ntawm lub qhov hloov ob qho tib si rhiab heev thiab txuag zog, txhim kho qhov kev paub ntawm tus neeg teb xov tooj. Tib lub sijhawm, nws qhov kub thiab txias kuj yog - 40 - 75 ° C, ua kom ntseeg tau tias qhov kev ua haujlwm ntawm lub qhov hloov ruaj khov thiab ntseeg tau hauv ntau qhov chaw ib puag ncig.
Lub tshuab hluav taws xob tswj lub qhov (electric pilot control valve) no muaj kev ua haujlwm zoo heev hauv kev muab hluav taws xob, kev xa xov, kev ua haujlwm kho tshuab thiab cov lus qhia hloov pauv, uas tsis muaj qhov tsis ntseeg tias muab kev lees paub zoo rau kev ua haujlwm ntse thiab meej ntawm lub tshuab khawb av. Nrog nws txoj kev nce qib thiab kev siv maj mam hauv kev ua lag luam, nws yuav txhawb nqa kev lag luam tshuab tsim kho mus rau qib siab dua thiab coj kev ua haujlwm zoo dua thiab kev txhim kho zoo rau ntau yam haujlwm tsim kho.
