Michina yekuvaka zvishongedzo EHPR08-33 yakarukwa katuriji vharafu

Proportional pressure valve kutadza kuongorora uye kubvisa

Ikozvino inoyerera nepakati peiyo proportional electromagnet yakakurisa, asi kudzvanywa kuchiri kusati kwakwira, kana kudzvanywa kunodiwa hakugone kutariswa panguva ino kupokana kwecoil yeproportional electromagnet, kana yakaderera kupfuura kukosha kwakatarwa, ipapo dunhu remukati. ye electromagnet coil yakaputsika; Kana iyo electromagnet coil kuramba yakajairwa, saka kubatana kune proportional amplifier ipfupi-inotenderera. Panguva ino, iyo proportional electromagnet inofanira kutsiviwa, uye chinongedzo chinofanira kubatanidzwa, kana coil rewound inofanira kuiswa.

Kana danho rekumanikidza richichinja, kudzvinyirirwa kwediki amplitude kunoramba kuripo, uye chikonzero chekusagadzikana kweiyo set pressure inonyanya kuti pane tsvina yakasungirirwa pakati pepakati peiyo proportional electromagnet uye inotungamira chikamu (gidi sleeve), iyo inotadzisa. kufamba kwepakati. Mukuwedzera, chikamu chinotsvedza che spool chikuru chakanamirwa netsvina, iyo inodzivisa kufamba kweiyo huru spool. Pamusana pemigumisiro yehutsvina iyi, hysteresis inowedzera. Muchikamu che hysteresis, dzvinyiriro haina kugadzikana uye dzvinyiriro inoramba ichichinja. Chimwe chikonzero ndechekuti kupfeka kwesimbi yesimbi uye magineti sleeve pair, gomba rinowedzera, uye kudzvinyirirwa kwakagadziriswa (kuburikidza nehumwe kukosha ikozvino) haina kugadzikana.

Panguva ino, valve uye proportional electromagnet inogona kuparadzaniswa kuti icheneswe, uye kusvibiswa kwemafuta e hydraulic kunogona kuongororwa. Kana ichipfuura mitemo, mafuta anofanira kuchinjwa; Nokuda kwekuregererwa kwakanyanya kunokonzerwa nekupfekedzwa kwesimbi yesimbi, zvichiita kuti kuwedzerwa kwesimba re hysteresis, zvichiita kuti kusagadzika kwekumanikidzwa kwemitemo, dhayamita yekunze yesimbi yesimbi inofanira kuwedzerwa kuti igare yakanyatsoenderana nemutungamiri sleeve.

Kupindura kwekumanikidzwa kunononoka uye kudzvanywa kunoshanduka zvishoma nezvishoma nekuti mweya uri muchikamu che electromagnet haubudiswe yakachena; Iyo yakagadziriswa orifice uye main valve orifice (kana kuti bypass orifice) yekunyorovesa pane electromagnet musimboti yakavharwa netsvina, uye kufamba kweiyo proportional electromagnet core uye main valve core inodziviswa zvisina basa; Mukuwedzera, mhepo inopinda muhurongwa, iyo inowanzoitika kana midziyo ichangobva kuiswa uye yakatanga kushanda kana kana mhepo inosanganiswa mushure mekuvhara kwenguva refu.
