Proportional siab valve tsis ua hauj lwm tsom xam thiab tshem tawm

Vim hais tias lub proportional siab valve tsuas yog nyob rau hauv lub hauv paus ntawm lub siab zoo tib yam valve, lub regulator kov yog hloov los ntawm ib tug proportional electromagnet. Yog li ntawd, ntau yam kev ua txhaum uas tsim los ntawm lub siab zoo tib yam li qub, uas tseem yuav ua rau muaj kev txhaum thiab tshem tawm txoj hauv kev ntawm lub siab zoo tib yam li qub kuj tseem muaj feem xyuam rau qhov sib npaug ntawm lub siab valve (xws li qhov sib thooj proportional relief valve), uas tuaj yeem ua tau. tuav los ntawm kev siv. Ntxiv rau:

① Raws li cov khoom siv hluav taws xob tsis muaj tam sim no los ntawm, kom qhov kev tswj xyuas tsis ua haujlwm ntawm lub sijhawm no tuaj yeem txheeb xyuas raws li cov ntsiab lus saum toj no "(1) proportional electromagnet fault" cov ntsiab lus. Thaum qhov kev tswj xyuas tsis ua haujlwm tau tshwm sim, koj tuaj yeem tshawb xyuas tus nqi tam sim no nrog lub ntsuas hluav taws xob los txiav txim seb puas muaj teeb meem nrog kev tswj xyuas hluav taws xob hluav taws xob, lossis teeb meem nrog cov khoom siv hluav taws xob sib npaug, lossis teeb meem nrog lub valve, uas. tuaj yeem ua mob.

② Txawm hais tias tam sim no ntws los ntawm cov khoom siv hluav taws xob sib npaug, tab sis lub siab tsis nce siab, lossis qhov xav tau siab tsis muaj, nruab nrab ntawm qhov sib npaug ntawm tus tsav siab tswj (lub nyem valve) thiab lub ntsiab nyem valve, tus tsav phau ntawv tswj. ntawm qhov zoo tib yam pilot nyem valve tseem khaws cia, uas plays lub luag hauj lwm ntawm kev ruaj ntseg valve ntawm no. Thaum lub valve tswj siab tsawg dhau, txawm hais tias qhov sib npaug ntawm electromagnet los ntawm qhov tam sim no tau ntsuas, tab sis lub siab tsis nce mus, yog tias lub valve teeb tsa siab qis dhau, tus tsav khiav tawm ntawm lub valve ntws rov qab mus rau lub tank, yog li ntawd. lub siab tsis tuaj. Nyob rau hauv cov ntaub ntawv no, lub valve teeb tsa siab yuav tsum tau nce li ntawm 1MPa tshaj qhov siab tshaj plaws ua hauj lwm siab ntawm lub valve.

(3) Tam sim no ntws los ntawm lub proportional electromagnet loj heev, tab sis lub siab tseem tsis tau nce, los yog qhov yuav tsum tau lub siab yuav tsum tsis txhob raug soj ntsuam nyob rau lub sij hawm no lub coil tsis kam ntawm proportional electromagnet, yog hais tias deb tsawg tshaj li tus nqi teev, ces. sab hauv Circuit Court ntawm electromagnet kauj yog tawg; Yog hais tias lub electromagnet coil tsis kam yog qhov qub, ces qhov kev sib txuas mus rau lub amplifier proportional yog luv luv. Lub sijhawm no, cov khoom siv hluav taws xob sib luag yuav tsum tau hloov pauv, thiab qhov kev sib txuas yuav tsum tau txuas nrog, lossis cov coil rewound yuav tsum tau nruab.
