Loader excavator lisebelisoa XKCH-00022 solenoid valve Hydraulic valve

Phapano ke efe lipakeng tsa valve ea proportional le valve e tloaelehileng ea solenoid?

Proportional valve ke mofuta o mocha oa sesebelisoa sa hydraulic control. Ka valve e tloaelehileng ea khatello, valve ea phallo le valve ea tataiso, motlakase o lekanang o sebelisoa ho nkela karolo ea taolo ea pele, ho latela motlakase o kenang.
Letšoao la khase le tsoela pele le ka tekano le laola khatello, phallo, kapa tsela ea molapo oa oli ka remoutu. Li-valve tse lekanang ka kakaretso li na le ts'ebetso ea matšeliso a khatello, 'me khatello ea phallo le sekhahla sa phallo li ka angoa ke liphetoho tsa mojaro.

1, valve e tloaelehileng ha e lekane le taolo e tsoelang pele ea mehato, ke sesebelisoa se hloekileng sa mofuta o le mong, tataiso ea ho bula li-valve, palo ea ho bula kapa matla a ho beha selemo ke 'nete.
E ke ke ea fetoloa ho latela maemo a sebele.

2, proportional valve e lekana le taolo e tsoelang pele ea mehato, ho latela maemo a nnete a fetohang tlhahisoleseling e bokelletsoeng ho taolo ea puseletso ea boiketsetso, tataiso ea ho bula valve, palo ea ho bula kapamatla a behiloeng nakong ea selemo a lateloa, ho finyella letoto la liphetoho tse tsoelang pele tse laoloang motsamaong. Taolo ea phallo ea li-valve e ka aroloa ka mefuta e 'meli: e' ngoe ke taolo ea switch: e ka buloa ka botlalo, kapa e koetsoe ka botlalo, phallo e kanna ea ba, kapa e nyane, ha e na boemo bo mahareng, joalo ka motlakase o tloaelehileng ka valve, valve ea motlakase e khutlisetsang morao, electro-hydraulic reversing. belofo. E 'ngoe ke taolo e tsoelang pele: sekepe sa valve se ka buloa ho ea ka tlhokahalo ea tekanyo leha e le efe ea ho bula, ka hona ho laola boholo ba phallo, li-valve tse joalo li na le taolo ea matsoho, tse kang li-valve tsa throttle, empa hape li laoloa ka elektronike, tse kang proportional. li-valve, li-valve tsa servo.

Molao-motheo oa ho sebetsa oa proportional valve:

Letšoao la taelo le matlafatsoa ke proportional amplifier, le proportional output current ho proportional solenoid ea proportional valve, proportional solenoid output force le motsamao o lekanang oa boemo ba mantlha ba valve, o ka laola ka tsela e lekanang phallo ea phallo ea metsi le fetola tsela eo metsi a phallang ka yona, e le ho fihlella boemo kapa taolo ya lebelo la sehlomathisi. Lits'ebetsong tse ling tse hlokang boemo bo phahameng kapa ho nepahala ha lebelo, sistimi ea taolo e koetsoeng e ka boela ea etsoa ka ho lemoha phallo kapa lebelo la actuator.
The proportional valve e entsoe ka DC proportional electromagnet le hydraulic valve. Moko-taba oa valve ea proportional ho hlokomela taolo e tsoelang pele ke karo-karolelano
Ho na le mefuta e mengata ea li-electromagnetic electromagnets, empa molao-motheo oa ts'ebetso o ts'oana, kaofela ha ona o ntlafatsoa ho latela litlhoko tsa taolo ea valve ea proportional.
