Xa kufikwa ekukhuselekeni kwiimeko zezulu, zimbalwa izinto ezintsha eziye zahlala ixesha elide njengesambrela esithobekileyo. Ngenxa yokuba sinamandla okusikhusela emvuleni, ekhephini, naselangeni eliqatha, isambrela siye saba yinto ebalulekileyo ebomini bethu bemihla ngemihla. Kodwa ngaba wakha wazibuza ngesayensi esekwe kubuchwepheshe besambrela? Yintoni eyenza ukuba sisebenze kangaka ekusigcineni somile okanye ekusinikeni umthunzi ngemini enelanga? Masingene kwihlabathi elinomtsalane lesayensi yesambrela size sityhile iimfihlo ezingasemva kwamandla ayo okukhusela.
Umsebenzi oyintloko wesambrela kukubonelela ngomqobo obonakalayo phakathi kwethu nezinto zendalo. Nokuba ngamathontsi emvula okanye imisebe yelanga, isambrela sisebenza njengekhaka, siwathintela ekufikeleleni emizimbeni yethu. Ukwakhiwa kwesambrela kulula ngokukhohlisayo kodwa kusebenza ngobuchule. Siqulathe isigqubuthelo, isakhiwo esixhasayo, kunye nesiphatho. Isigqubuthelo, esidla ngokwenziwa ngelaphu elingangeni manzi, sisebenza njengomaleko oyintloko wokukhusela.
Ubuchule besambrela bokugxotha amanzi bubangelwa zizinto ezahlukeneyo. Okokuqala, ilaphu elisetyenziselwa i-canopy liphathwa nge-coating engangeni manzi, efana ne-polyurethane okanye i-Teflon, edala umqobo othintela amanzi ukuba angangeni. Ukongeza, ilaphu lilukiwe ngokuqinileyo ukuze kuncitshiswe izithuba phakathi kweefayibha, nto leyo ephucula ngakumbi ukungakwazi kwalo ukuxhathisa amanzi. Xa amathontsi emvula ewela kwi-canopy, ayaqengqeleka endaweni yokuphuma, nto leyo esenza some ngaphantsi.
Ulwakhiwo oluxhasayo lwesambrela luyilelwe ukunika uzinzo namandla. Uninzi lweesambrela zisebenzisa inkqubo yeembambo eziguquguqukayo ezenziwe ngezinto ezifana ne-fiberglass okanye isinyithi. Ezi mbambo zinamathele kwi-shaft ephakathi, eqala kwisibambo ukuya phezulu kwekhanophi. Iimbambo zenzelwe ukugoba nokusasaza amandla omoya okanye olunye uxinzelelo lwangaphandle, ukuthintela isambrela ukuba singawi okanye sijike ngaphakathi.
