Kev siv cov kev taw qhia valve hauv hydraulic system

Cov kev taw qhia valve yog kev tswj thiab tswj cov khoom hauv hydraulic system. Nws lub luag haujlwm tseem ceeb yog hloov cov kev taw qhia ntawm cov roj ntws thiab tswj cov kev taw qhia ntawm lub actuator. Nyob rau hauv tus txheej txheem ntawm kev tsim thiab siv lub tshuab hydraulic, qee zaum vim yog kev xaiv tsis raug ntawm cov kev taw qhia valve, qee qhov kev ua haujlwm ntawm hydraulic system raug cuam tshuam, thiab txawm tias muaj teeb meem tshwm sim. Kab lus no sau ntau yam piv txwv ntawm daim ntawv thov ntawm kev taw qhia li qub hauv cov tshuab hydraulic, tshuaj xyuas cov laj thawj rau kev siv tsis raug, thiab muab txoj kev siv kom raug.

1 Tsim nyog siv cov kev taw qhia valve hauv kev ntsuas hluav taws xob

Lub luag haujlwm ntawm lub ntsuas phoo Circuit Court yog ua kom lub actuator

Nyob ntawm txhua txoj haujlwm, thiab yuav tsis txav mus rau txoj haujlwm vim muaj zog sab nraud tom qab nyob. Xauv Circuit Court (bidirectional hydraulic xauv) siv hydraulically tswj valve. Lub valve tseem ceeb ntawm hydraulic tswj xyuas valve feem ntau yog cov qauv poppet nrog me ntsis sab hauv to. Kev ntsuas qhov tseeb tsuas yog nyob ntawm qhov to ntawm tus actuator. Qhov ntsuas qhov tseeb yog qhov siab. Txhawm rau kom ntseeg tau tias qhov kev ua tau zoo ntawm lub xauv hydraulic, H- lossis Y-hom reversing valve yuav tsum raug xaiv hauv Circuit Court. Thaum lub actuator nyob rau hauv lub predetermined nres txoj hauj lwm, lub reversing valve nyob rau hauv nruab nrab txoj hauj lwm.Qhov chaw nres nkoj ntawm lub hydraulic tswj xyuas valve yog ncaj qha mus rau lub roj tank los ntawm nruab nrab txoj hauj lwm ntawm lub reversing valve. Lub siab tswj yog tag nrho unloaded. Lub tog raj kheej raug kaw vim tias ob lub chamber roj raug kaw. Txoj hauj lwm ntawm qhov chaw nruab nrab ntawm qhov rov qab valve tau raug xaiv tsis raug rau ntawm qhov chaw.Tus sau ib zaug hu rau lub tumbler ntawm lub tshuab fais fab. Kev ua haujlwm ntawm lub ntsuas phoo hluav taws xob thim rov qab valve hauv hydraulic system yog M hom, thiab qee zaum qhov ntsuas phoo tsis zoo. Tom qab qhov kev ua haujlwm ntawm qhov taw qhia valve, qhov kev ua haujlwm ntawm kev kaw haujlwm tau zoo heev. Yog vim li cas rau qhov no yog tias qhov kev ua haujlwm nruab nrab ntawm qhov kev taw qhia valve ntawm thawj qhov system tsis raug xaiv kom raug. Thaum cov kev taw qhia valve ntawm M-hom muaj nuj nqi nyob rau hauv nruab nrab txoj hauj lwm, cov roj siab ntawm qhov chaw nres nkoj tswj ntawm hydraulic check valve tsis tuaj yeem ploj mus sai li sai tau, thiab hydraulic xauv tsis tuaj yeem kaw tam sim ntawd. Yog li cov nyhuv xauv tsis zoo.

2 Tsim nyog siv cov kev taw qhia valve hauv clamping roj Circuit Court

Ntawm qee qhov CNC lathes thiab semi-automatic lathes, hydraulic chucks uas tswj clamping thiab loosening ntawm workpieces los ntawm hydraulic transmissions yog dav siv. Lub hydraulic chuck feem ntau yog tswj los ntawm lub siab txo Circuit Court (clamping roj Circuit Court) nyob rau hauv hydraulic system, thiab lub workpiece yog clamped thiab tso tawm los ntawm ib tug chuck mechanical ntaus ntawv. Yog li ntawd, nyob rau hauv tas li ntawd mus rau lub tsim ntawm lub clamping roj Circuit Court, nyob rau hauv tas li ntawd mus muab ib tug ruaj khov thiab txaus siab clamping quab yuam, ib tug tseem ceeb qhov teeb meem yog los xyuas kom meej kev ruaj ntseg thiab kev cia siab ntawm lub workpiece clamping.

Kev xaiv ntawm qhov taw qhia valve yog qhov tseem ceeb heev rau kev nyab xeeb ntawm cov khoom siv. Kev xaiv lub hauv paus ntsiab lus ntawm qhov thim rov qab valve yuav tsum yog: txawm tias cov khoom siv tam sim ntawd tawm thaum lub sijhawm ua haujlwm, lub chuck tseem tuaj yeem ntseeg tau clamp lub workpiece. Yog li ntawd, ob txoj hauj lwm electromagnetic directional valve uas yog clamped ntawm lub hwj chim tsis ua hauj lwm feem ntau yog siv. Yog tias koj xaiv ob txoj hauj lwm electromagnetic directional valve uas yog clamped los ntawm hluav taws xob, lub chuck yuav loosen thiab lub workpiece tseem yuav tig thaum lub hwj chim yog dheev txiav tawm nyob rau hauv ib qho kev npaj txhij txog. Qhov tshwm sim yog qhov xav tsis thoob. Tsis tas li ntawd, txhawm rau kom tsis txhob muaj teeb meem xws li lub hwj chim-on clamping, ob txoj haujlwm electromagnetic directional valve nrog lub cim xeeb muaj nuj nqi (tsis siv neeg rov pib dua) tuaj yeem xaiv. Thaum lub hwj chim tawm, txoj hauj lwm ntawm lub valve tseem ceeb ntawm qhov taw qhia valve tsis hloov thiab cov roj hluav taws xob tsis hloov. . Qhov thib ob, xaiv peb txoj haujlwm valve (O-type lossis M-type function) kuj yog ib txoj hauv kev tsim nyog xav txog.
