Ivalvu yokulawula ukugeleza kwe-cartridge valve LFR10-2A-K

I-valve yesinxephezelo sokucindezela

Ngokwesimo se-valve yesinxephezelo sokucindezela kuwo wonke umjikelezo we-hydraulic, uhlelo lokulawula isinxephezelo sengcindezi ethwala umthwalo lungabuye luhlukaniswe ohlelweni oluzwelayo lwe-pre-valve yesinxephezelo somthwalo kanye nesistimu ye-post-valve yesinxephezelo somthwalo womthwalo. Isinxephezelo sangaphambi kwevalvu sisho ukuthi ivalvu yesinxephezelo somfutho ihlelwa phakathi kwephampu kawoyela kanye nevalvu yokulawula, kanti isinxephezelo se-post-valve sisho ukuthi ivalvu yesinxephezelo sokucindezela ihlelwa phakathi kwevalvu yokulawula kanye ne-actuator. Isinxephezelo sangemuva kwevalvu sithuthuke kakhulu kunesinxephezelo sangaphambi kwevalvu, ikakhulukazi esimweni sokungatholakali kukawoyela wephampu okwanele. Uma ukunikezwa kukawoyela kwepompo kunganele, i-valve eyinhloko enxeshezelwa ngaphambi kokuba i-valve izoholela ekugelezeni okwengeziwe emthwalweni wokukhanya kanye nokugeleza okuncane emthwalweni osindayo, okungukuthi, umthwalo wokukhanya uhamba ngokushesha, futhi i-actuator ngayinye ingaphandle kokuvumelanisa. lapho kwenziwa isenzo esihlanganisiwe. Kodwa-ke, isinxephezelo sangemuva kwe-valve asinayo le nkinga, izosabalalisa ukugeleza okuhlinzekwa yipompo ngokulingana, futhi ivumelanise zonke izakhi ezisebenzayo ngesikhathi sesenzo esihlanganisiwe. Isistimu yokuzwa umthwalo ihlukaniswe yaba isinxephezelo sangaphambi kwevalvu kanye nesinxephezelo se-post-valve. Lapho imithwalo emibili noma ngaphezulu isebenza ngesikhathi esifanayo, uma ukugeleza okuhlinzekwa yipompo enkulu kwanele ukuhlangabezana nokugeleza okudingekayo ohlelweni, imisebenzi yesinxephezelo se-pre-valve kanye nesinxephezelo se-post-valve ifana ncamashi. Uma ukugeleza okuhlinzekwa yipompo enkulu kungakwazi ukuhlangabezana nokugeleza okudingekayo yisistimu, isinxephezelo ngaphambi kwe-valve kanje: ukugeleza kwepompo eyinhloko kuqala kunikeza ukugeleza komthwalo ngomthwalo omncane, bese unikeza ukugeleza. kweminye imithwalo lapho izidingo zokugeleza zomthwalo onomthwalo omncane zihlangene; Isimo sesinxephezelo se-post-valve siwukuthi: ukunciphisa ukugeleza komthwalo womthwalo ngamunye uma kuqhathaniswa nesikhathi esifanayo sangonyaka odlule (ukuvulwa kwevalvu) ukuze kuzuzwe umphumela wesenzo esihlanganisiwe. Okungukuthi, lapho ukugeleza okuhlinzekwa yipompo eyinhloko kungakwazi ukuhlangabezana nokugeleza okudingekayo yisistimu, ukusatshalaliswa kokugeleza kunxeshezelwe ngaphambi kokuba i-valve ihlotshaniswe nomthwalo, kuyilapho ukusatshalaliswa kokugeleza kunxeshezelwa ngemva kokuba i-valve ingahlobene nomthwalo, kodwa kuphela. okuhlobene nenani lokuvula le-valve eyinhloko.
