TM70301 proportional solenoid vharafu hydraulic pombi yekuchera zvinhu

Iyo screw cartridge proportional valve is threaded electromagnetic proportional cartridge component yakagadziriswa paoiri circuit assembly block. Iyo screw cartridge valve ine maitiro ekugadzirisa kushandiswa, pombi yekuchengetedza uye kuderera kwehuni kuumbwa, nezvimwewo. Yakashandiswa zvakanyanya uye zvakanyanya mumichina yekuvaka mumakore achangopfuura. Inowanzo shandiswa spiral cartridge type proportional valve ine maviri, matatu, mana uye akawanda-pass mafomu, maviri-nzira proportional vharafu main proportional throttle vharafu, kazhinji zvikamu zvayo pamwe chete kuumba composite vharafu, kuyerera, kudzvinyirira kudzora; Zvisungo zvitatu
Iyo proportional vharafu ndiyo hombe yakaenzana kudzvinyirira kudzikisa vharafu, inova zvakare inonyanya kushandiswa proportional vharafu mune mobile mechanical hydraulic system, iyo inonyanya kushandisa hydraulic multiway valve pilot mafuta circuit. Iyo nzira nhatu-yakaenzana kudzvinyirirwa kuderedza vharuvhu inogona kutsiva iyo yechinyakare dhizaini yekudzikisa pilot valve, iyo ine kuchinjika kwakawanda uye yakakwirira kudzora kurongeka kupfuura iyo manual pilot valve. Inogona kugadzirwa kuva proportional servo control manual multi-way valve sezvakaratidzwa muFigure 1. Nezviratidzo zvakasiyana-siyana zvekupinza, mhepo inoderedza mhepo inoita kuti piston inobuda ive yakasiyana-siyana kana kuti inoyerera kuti iwane kuenzanirana kwekutonga kwekudzingwa kwevakawanda-vakawanda. nzira vharafu spool. Four-nzira kana multi-nzira screw cartridge proportional mavharuvhu anogona mumwe nomumwe kudzorwa nokuda kushanda mudziyo.
Iyo slide valve type proportional valve, inozivikanwawo sevhavha yekugovera, ndechimwe chezvinhu zvakakosha zveiyo mobile mechanical hydraulic system, iyo inogona kuona gwara uye kuyerera kurongeka kwevhavha inoumbwa.
Electro-hydraulic slide valve proportional multiway valve inonyatsokodzera electro-hydraulic conversion control element, inochengetedza basa rekutanga remanyoro multiway valve, asiwo inowedzera nzvimbo yemagetsi mhinduro proportional servo kushanda uye mutoro unonzwa uye dzimwe nzira dzepamusoro dzekutonga, ndiyo michina yekuvaka yekugovera vharafu inotsiva zvigadzirwa.
Nekuda kwekutariswa kwemitengo yekugadzira uye yekuvaka michina yekudzora kurongeka kwezvinodiwa hazvisi hunhu hwepamusoro, iyo yakawanda proportional multi-nzira vharafu haina kuisirwa displacement sensor, nemagetsi kuona uye kukanganisa kururamisa mabasa. Kutamiswa kwe spool kunokanganisa nyore nyore nekudzvinyirira kunokonzerwa nekuchinja kwemutoro, uye kutarisa kwekuona kunodiwa kuti kuve nechokwadi chekupedzwa kwekushanda panguva yekushanda. Electronic control, remote control operation inofanirwa kubhadhara zvakanyanya kupesvedzero yekupindira kwekunze. Munguva pfupi yapfuura, nekuvandudzwa kwehunyanzvi hwemagetsi, vanhu vari kushandisa kuwedzera uye kuwedzera mukati kurongedza
Displacement sensors senge dynamic transformer (LDVT) inoshandiswa kuona kufamba kwe spool chinzvimbo uye kuona yakavharwa-loop kudzora kwe spool displacement. Iyi yakanyatsobatanidzwa vharafu ine solenoid proportional valve, chinzvimbo chemhinduro sensor, drive amplifier uye mamwe maseketi emagetsi.
