Ngatitaurei nezvekushanda zvakanaka kwefirita, kumhanya kwepamusoro uye kumhanya kwefirita kwemafirita ehepa. Mafirita ehepa nemafirita eulpa anoshandiswa pakupera kwekamuri rakachena. Maumbirwo awo anogona kukamurwa kuita: firita yehepa pleat mini uye firita yehepa yakadzama.
Pakati pazvo, maparamita ekushanda kwemafirita ehepa anosarudza mashandiro avo ekusefa anobudirira zvikuru, saka kudzidza maparamita ekushanda kwemafirita ehepa kune kukosha kukuru. Zvinotevera ipfupiso yekushanda kwemafirita, kumhanya kwepamusoro, uye kumhanya kwemafirita ehepa:
Kumhanya kwepamusoro uye kumhanya kwefirita
Kumhanya kwepamusoro uye kumhanya kwefirita kwefirita yehepa zvinogona kuratidza kugona kwemhepo kwefirita yehepa. Kumhanya kwepamusoro kunoreva kumhanya kwemhepo pachikamu chefirita yehepa, inowanzo ratidzwa mu m/s, V=Q/F*3600. Kumhanya kwepamusoro chinhu chakakosha chinoratidza hunhu hwechimiro chefirita yehepa. Kumhanya kwefirita kunoreva kumhanya kwemhepo pamusoro penzvimbo yezvinhu zvefirita, inowanzo ratidzwa mu L/cm2.min kana cm/s. Kumhanya kwefirita kunoratidza kugona kwepasi kwezvinhu zvefirita uye mashandiro ekusefa kwezvinhu zvefirita. Kumhanya kwefirita kwakaderera, kazhinji kutaura, kushanda kwepamusoro kunogona kuwanikwa. Kumhanya kwefirita kunobvumirwa kupfuura nepakati kwakaderera uye kuramba kwezvinhu zvefirita kwakakura.
Kushanda zvakanaka kwefirita
"Kushanda zvakanaka kwesefa" kwesefa yehepa ihuremu hwehuwandu hweguruva rakatorwa kusvika kuguruva riri mumhepo yekutanga: kushanda zvakanaka kwesefa = huwandu hweguruva rakatorwa nesefa yehepa/guruva riri mumhepo yepamusoro = 1-guruva riri mumhepo yepasi/kumusoro. Zvinoreva kushanda zvakanaka kweguruva remhepo zvinoita sezviri nyore, asi zvarinoreva uye kukosha kwaro zvinosiyana zvikuru zvichienderana nenzira dzakasiyana dzekuyedza. Pakati pezvinhu zvinosarudza kushanda zvakanaka kwesefa, "huwandu" hweguruva hune zvahunoreva zvakasiyana, uye kukosha kwekushanda zvakanaka kwesefa yehepa kwakaverengwa nekuyerwa kunosiyanawo.
Mukuita, pane huremu hweguruva rose nehuwandu hweguruva; dzimwe nguva huwandu hweguruva rehukuru hwechimedu chakajairika, dzimwe nguva huwandu hweguruva rese; kunewo huwandu hwechiedza hunoratidza zvisina kunanga huwandu hwechinhu uchishandisa nzira chaiyo, huwandu hwe fluorescence; kune huwandu hwenguva pfupi hwemamiriro akati, uye kunewo huwandu hwakayerwa hwehuwandu hwekushanda zvakanaka kwemaitiro ese ekugadzira guruva.
Kana firita rehepa rimwe chete rikaedzwa uchishandisa nzira dzakasiyana, kukosha kwekushanda kwakayerwa kuchasiyana. Nzira dzekuyedza dzinoshandiswa nenyika dzakasiyana nevagadziri hadzina kufanana, uye dudziro uye kuratidzwa kwekushanda kwefirita rehepa kwakasiyana zvikuru. Pasina nzira dzekuyedza, kushanda kwefirita hakugoneke kutaura nezvako.
