Ukuvala kwenzelwa ukukhandela ukuvuza, begodu umthetho wokuvala amavalvu nawo ufundwa ukusuka ekuvimbeleni ukuvuza. Zinengi izinto ezithinta ukusebenza kokuvalaamavalvu wevithamini, khulukhulu okufaka hlangana okulandelako:
1. Isakhiwo sokuvala
Ngaphasi kokutjhuguluka kwezinga lokutjhisa nofana amandla wokuvala, isakhiwo separa yokuvala sizokutjhuguluka. Ngaphezu kwalokho, ukutjhuguluka lokhu kuzokuthinta begodu kutjhugulule amandla hlangana namabili wokuvala, ngaleyo ndlela kwehlise ukusebenza kokuvala kwevalvu. Ngalokho-ke, lokha nawukhetha isivalo, qiniseka bona ukhetha isivalo esine-elastic deformation. Ngesikhathi esifanako, tjheja nobukhulu bendawo yokuvala. Isizathu kukobana indawo yokuthintana yephara yokuvala angeze yafaniswa ngokupheleleko. Lokha ububanzi bendawo yokuthintana kwendawo yokuvala bukhula, amandla atlhogekako wokuvala ayanda.
2. Umfutho othileko wokuvala indawo
Umfutho othileko wephasi lokuvala uthinta ukusebenza kokuvalaivalvu yevivanekanye nepilo yesevisi yevalvu. Ngalokho-ke, umfutho othileko wendawo yokuvala nawo uyinto eqakathekileko khulu. Ngaphasi kweemeko ezifanako, ukugandeleleka okuphezulu khulu kuzokubangela ukulimala kwevalvu, kodwana ukugandeleleka okuncani khulu kuzokubangela ukuvuza kwevalvu. Ngalokho-ke, kufuze sicabangele ngokuzeleko ukufaneleka komfutho othileko lokha nasiklama.
3. Izakhiwo eziphathekako zomkhathi
Iimpawu eziphathekako ze-medium nazo zithinta ukusebenza kokuvalaivalvu yevivane. Iimpawu eziphathekako zifaka hlangana amazinga womtjhiso, ukuqina, kanye nokuthanda amanzi kwephasi, hlangana nezinye. Ukutjhuguluka kwamazinga womtjhiso akuthinti ukubogaboga kwephara lokuvala nokutjhuguluka kobukhulu beengcenye kwaphela, kodwana kunobudlelwano obungahlukaniswako nokunamathelana kwegesi. Ukuthamba kwegesi kuyakhuphuka nofana kwehle ngokukhula nofana ukwehla kwezinga lokutjhisa. Ngalokho-ke, ukwenzela bona kwehliswe umthelela wezinga lokutjhisa ekusebenzeni kokuvala kwevalvu, lokha nasiklama umbhangqwana wokuvala, kufanele siwuklame njengevalvu enokubuyiselwa kwe-thermal njengesihlalo sevalvu esine-elastic. Ukunamathelana kuhlobana nokungena kwamanzi. Lokha ngaphasi kwemibandela efanako, lokha i-viscosity nayikulu, ikghono lokungena eliphasi le-fluid. Ukuthanda amanzi kwendawo kutjho bona lokha nakunefilimu phezu kwendawo yensimbi, ifilimu kufanele isuswe. Ngebanga lefilimu ye-oli encani khulu, izokubhubhisa ukuthanda amanzi kwendawo, okurholela ekuvalekeni kwemisele yamanzi.
4. Ikhwalithi yepara yokuvala
Ikhwalithi yepara yokuvala ikakhulukazi itjho bona kufuze sihlole ukukhethwa, ukumadanisa nokunemba kokukhiqiza kwezinto. Ukwenza isibonelo, idiski yevalvu ifanelana kuhle nendawo yokuvala isihlalo sevalvu, okungathuthukisa ukusebenza kokuvala.
Ukuvuza kwamavalvu kuvame khulu epilwenakho nekukhiqizeni, okungabangela ukulahlwa nofana kulethe ingozi epilwenakho, njengokuvuza kwamavalvu wamanzi wempompi, nemiphumela emimbi, njengobuthi, ubungozi, ukuvutha, ukuqhuma kanye nokuvuza kwemidiya ebolako, njll., kuyingozi ekulu ekuphepheni komuntu mathupha, ekuphepheni kwepahla kanye neengozi zebhoduluko. Khetha ama-seal afaneleko ngokuya ngeendawo ezihlukileko begodu usebenzise ubujamo.
