Zombini zisebenza umsebenzi oyintloko wokulawula ukuhamba kwamanzi kodwa zahlukile ngokusisiseko kwindlela ezisebenza ngayo kunye neendlela ezisetyenziswa ngayo. Esi sikhokelo sibonelela ngothelekiso oluneenkcukacha, olungenamkhethe olugubungela iinkcazo zazo, imigaqo yokusebenza, iingenelo, iingxaki, ukugcinwa, kunye neendlela zokukhetha eziphambili ukukunceda wenze ukhetho olunolwazi.
1. Iinkcazo kunye neMigaqo-nkqubo yoQeqesho oluPhambili
Yintoni iValve eSebenza ngoMbane?
An Ivalvu Esebenza Ngombaneisebenzisa i-motor yombane njengomthombo wayo wamandla oyintloko. Iguqula amandla ombane abe yi-mechanical torque ukuze isebenze i-valve stem, ivumela ulawulo oluvulekileyo, oluvalayo, okanye olulawulayo. Inkqubo idla ngokuhlanganisa i-motor, iyunithi yokunciphisa iigiya, umzimba we-valve, kwaye idla ngokuba yi-smart electronic controller ukuze ibekwe ngokuchanekileyo.
Yintoni iValve eSebenzayo yePneumatic?
A Ivalvu eSebenzayo yoMoyaixhomekeke emoyeni ocinezelweyo (ngesiqhelo iibha ezi-4-7) ukuvelisa amandla. Umoya ocinezelweyo uqondiswa kwisilinda yivalvu yesolenoid, ityhala ipiston eshukumisa isiqu sevalvu. Le nkqubo ifuna izixhobo ezixhasayo ezifana ne-air compressor, izihluzi, izomisi, kunye nabalawuli ukuqinisekisa ukunikezelwa komoya ococekileyo nozinzileyo.
