S-Valve vs. Skirt Valve in Concrete Pump Trucks: Why S-Valve is Superior?​ 

Ka thepa ea ho pompa konkreite, valve ea kabo, e le karolo ea mantlha, e ama ka ho toba katleho ea kaho le bophelo ba tšebeletso ea thepa. Li-valve tsa S-valve le li-skirt ke li-valve tse peli tse tloaelehileng, empa S-valve e fetohile khetho ea pele bakeng sa merero e mahareng le e meholo ka lebaka la moralo oa eona oa sebopeho le melemo ea ts'ebetso.

Mabapi le ts'ebetso ea ho tiisa, S-valve e nka mohaho oa ho tiisa ka rotary, oo ka ho toba o lefellang ho roala ka har'a selemo sa rabara, ho boloka ts'ebetso e ntle ea ho tiisa nako e telele le ho fokotsa ka katleho kotsi ea ho lutla ha konkreite. Ka lehlakoreng le leng, valve ea skirt e itšetlehile ka ho lekana ka thata pakeng tsa seaparo sa rabara le lesale la ho itšeha bakeng sa ho tiisa. Sesepa se na le tšekamelo ea ho fetoha ka mor'a ho angoa ke lisebelisoa, tse hlokang ho nkeloa sebaka khafetsa ha litiiso

Mabapi le ho ikamahanya le maemo, S-valve e na le mefuta e mengata e fapaneng ea ho ikamahanya le boholo ba konkreite le ho putlama. E khona ho pompa konkreite ka li-aggregate tse mahoashe joalo ka majoe a pshatlehileng le majoana, haholo-holo a loketseng kaho ea konkreite e matla le e phahameng. Leha ho le joalo, valve ea skirt e loketse haholoanyane bakeng sa li-aggregates tse ntle le lisebelisoa tse tlaase, 'me e na le bothata ba ho thibela liphaephe tlas'a maemo a thata a ho sebetsa.

Mabapi le litšenyehelo tsa tlhokomelo, senotlolo sa ho roala likarolo tsa S-valve (tse kang ho roala lipoleiti le mehele ea ho itšeha) li bonolo ho nkela sebaka, 'me bophelo ba bona ba tšebeletso bo ka fihla makhetlo a 1.5-2 ho feta valve ea skirt. Ka lebaka la ho sebetsa ka potlako ha litiiso, valve ea skirt ha e hloke feela ho nkeloa sebaka khafetsa empa hape e hloka ho aroloa ha likarolo tse ling, ho eketsa nako ea ho fokotsa nako bakeng sa tlhokomelo le litšenyehelo tsa basebetsi.

Mabapi le katleho ea ho pompa, moralo oa mocha oa phallo oa S-valve o lumellana haholoanyane le melao-motheo ea mechine ea mokelikeli, e leng se fellang ka ho hanyetsa lintho tse fokolang tse fetang. Phallo ea eona e lekantsoeng e phahame ka 5% -10% ho feta ea li-valve tsa skirt tsa litlhaloso tse tšoanang, tse finyellang litlhoko tsa ho pompa ho tsoelang pele mererong e meholo.

Ka kakaretso, melemo e felletseng ea S-valve mabapi le ts'epo ea ho tiisa, maemo a ho sebetsa a feto-fetoha le maemo, moruo le katleho li etsa hore e be khetho e ka sehloohong bakeng sa literaka tsa pompo tsa konkreite tsa sejoale-joale, tse loketseng haholo maemo a kaho a phahameng haholo le a batloang haholo.
