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

Tam sim no ntws los ntawm proportional electromagnet yog loj heev, tab sis lub siab tseem tsis tau nce, los yog qhov yuav tsum tau lub siab tsis tuaj yeem soj ntsuam lub sij hawm no lub coil kuj ntawm proportional electromagnet, yog hais tias deb tsawg tshaj li tus nqi teev, ces lub internal circuit. 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.

Thaum lub siab hloov pauv, lub siab hloov pauv ntawm qhov me me amplitude yog qhov tsis tu ncua, thiab qhov laj thawj rau qhov tsis txaus ntseeg ntawm qhov teeb tsa siab yog qhov tseem ceeb yog tias muaj cov av txuas ntawm cov tub ntxhais ntawm cov khoom siv hluav taws xob sib npaug thiab cov lus qhia (lub tes tsho qhia), uas cuam tshuam. kev txav ntawm lub hauv paus. Tsis tas li ntawd, zawv zawg ib feem ntawm lub ntsiab spool yog daig nrog av, uas cuam tshuam kev txav ntawm lub ntsiab spool. Vim cov teebmeem ntawm cov qias neeg no, hysteresis nce. Nyob rau hauv lub Scope ntawm hysteresis, lub siab yog unstable thiab lub siab fluctuates tas li. Lwm qhov laj thawj yog qhov hnav ntawm cov tub ntxhais hlau thiab lub tes tsho sib nqus, qhov sib txawv nce, thiab kev hloov siab siab (los ntawm qee tus nqi tam sim no) tsis ruaj khov.

Lub sijhawm no, lub valve thiab proportional electromagnet tuaj yeem raug tshem tawm rau kev ntxuav, thiab cov pa phem ntawm cov roj hydraulic tuaj yeem kuaj xyuas. Yog tias nws dhau qhov kev cai, cov roj yuav tsum tau hloov pauv; Rau kev tshem tawm ntau dhau los ntawm kev hnav ntawm cov tub ntxhais hlau, ua rau kom muaj zog hysteresis, uas ua rau muaj kev tswj xyuas tsis ruaj khov, cov txheej txheem sab nraud ntawm cov tub ntxhais hlau yuav tsum tau nce ntxiv kom muaj kev sib haum xeeb nrog lub tes tsho qhia.

Lub siab teb yog sluggish thiab lub siab hloov maj mam vim hais tias cov huab cua nyob rau hauv proportional electromagnet tsis tawm huv si; Lub qhov rooj ruaj khov thiab lub ntsiab valve orifice (los yog bypass orifice) rau damping ntawm lub electromagnet core yog thaiv los ntawm cov av, thiab lub zog ntawm proportional electromagnet core thiab lub ntsiab valve tseem ceeb yog hindered yam tsis tsim nyog; Tsis tas li ntawd, huab cua nkag mus rau hauv qhov system, uas feem ntau tshwm sim thaum cov khoom siv tau nyuam qhuav tau nruab thiab pib ua haujlwm lossis thaum huab cua sib xyaw tom qab kaw lub sijhawm ntev.
