Intoki Igikoresho ntarengwa

Igikoresho cyifashishwa mu kugabanya amazi (Casagrande) gikoreshwa kugirango hamenyekane ubuhehere ubutaka bwibumba buva muri plastiki bugana mumazi.Ibikoresho bigizwe na crank na cam uburyo bushobora guhindurwa, konte yo gukubita hamwe nigikombe cyumuringa kivanwaho cyashyizwe kumurongo.

Imetero yubwoko bwamazi ikoreshwa mugupima imipaka yubutaka.Nibikoresho bikoreshwa mugushushanya no kubaka murwego rwo gutondekanya ubwoko bwubutaka, kubara imiterere karemano hamwe nuburinganire bwa plastike.

Uburyo bw'igerageza

1. Shira icyitegererezo cyubutaka mu isahani ihumeka, ongeramo ml 15 kugeza kuri 20 zamazi yatoboye, kongeramo inshuro nyinshi hanyuma ubikate hamwe nicyuma gihindura ubutaka kugeza kivanze neza, hanyuma ushyiremo ml 1 kugeza kuri 3 buri gihe, hanyuma ubivange neza ukurikije uburyo bwavuzwe haruguru.byose.

2. Iyo ibikoresho byubutaka bivanze namazi ahagije kugirango bigere kumurongo, bihwanye no gukenera kugabanuka inshuro 30 kugeza kuri 35 kugirango uhuze.Shira igice cya paste y'ibumba mumisahani hejuru aho isahani ikora ku isahani yo hepfo.Koresha icyuma gihindura ubutaka kugirango ukande paste yubutaka muburyo runaka, witondere kuyikanda inshuro nke zishoboka, kandi wirinde ibisebe kuvangwa mubutaka bwubutaka.Koresha icyuma gihindura ubutaka kugirango woroshye hejuru yubutaka bwubutaka, kandi igice kinini cyubutaka bwubutaka gifite cm 1 z'ubugari.Ubutaka burenze busubizwa mu isahani ihumeka, hanyuma umutaka wubutaka mu isahani ucagagurwa kuri diameter hamwe na grooveri ukurikira kamera.Ahantu hasobanuwe neza, hasobanuwe ahantu hashyizweho.Kugirango wirinde inkombe ya ruhago gutanyagurika cyangwa paste yubutaka iranyerera mu isahani, byibuze inkoni esheshatu kuva imbere kugeza inyuma no kuva inyuma kugeza imbere zemerewe gusimbuza igikoni kimwe, kandi buri nkoni igenda yimbuka buhoro buhoro kugeza igihe cyanyuma.Guhuza gukomeye hepfo yisahani bigomba gutangwa inshuro nke zishoboka.

3. Hindura ingofero ya F ku muvuduko wa revolisiyo 2 ku isegonda kugirango isahani yubutaka izamuke kandi igwe kugeza igice cya kabiri cyubutaka bwubutaka bukora munsi yigitereko hafi ya santimetero 1/2 (mm 12,7).Andika umubare wibitego bisabwa kuri 1/2 cm z'uburebure bwa groove hepfo.

4. Kata igice cyubutaka butumbereye kumurongo uva kuruhande rwubutaka kugera kuruhande, ubugari bwacyo bugereranywa nubugari bwicyuma gikata ubutaka, harimo nubutaka buri ahantu hafunze, ubishyire mubisanduku bikwiye bipima, gupima no kubihuza.Andika.Guteka ibiro bihoraho kuri 230 ° ± 9 ° F (110 ° ± 5 °).Ako kanya nyuma yo gukonja na mbere yo konsa mumazi yamamajwe, bapima.Andika kugabanuka nyuma yo gukama nkuburemere bwamazi.

5. Himura ubutaka busigaye mu isahani ku isahani ihumeka.Karaba kandi wumishe isahani hamwe na groover, hanyuma wongere usubize isahani kubushakashatsi butaha.

6. Koresha ibikoresho byubutaka byimuriwe mu isahani ihumeka kugirango wongere amazi kugirango wongere amazi yubutaka, kandi ukore byibuze ubundi bushakashatsi bubiri ukurikije uburyo bwavuzwe haruguru.Ikigamijwe ni ukubona icyitegererezo cyubutaka butandukanye, kandi umubare wibitonyanga bisabwa kugirango ingingo za paste yubutaka zitembera hamwe zirenze cyangwa munsi yinshuro 25.Umubare wibitonyanga byabonetse ugomba kuba hagati yinshuro 15 na 35, kandi icyitegererezo cyubutaka burigihe gikorwa kuva cyumutse kijya kumera neza mugupimisha.

7. Kubara

a Kubara ibirimo amazi WN yubutaka, bigaragazwa nkijanisha ryubutaka bwumye;

WN = (uburemere bwamazi weight uburemere bwubutaka bwumye) × 100

8. Shushanya umurongo wa plastike

Tegura 'plastike itemba umurongo' ku mpapuro-logarithmic;byerekana isano iri hagati yibirimo byamazi numubare wibitonyanga.Fata ibirimo amazi nka abscissa hanyuma ukoreshe igipimo cyimibare, hanyuma ukoreshe umubare wibagwa nkibisanzwe hanyuma ukoreshe igipimo cya logarithmic.Inzira ya plastike itemba ni umurongo ugororotse, ugomba kunyura mu manota atatu cyangwa menshi yikizamini uko bishoboka.

9. Imipaka ntarengwa

Ku mugezi utemba, amazi yatonyanga 25 yafashwe nkurugero rwamazi yubutaka, kandi agaciro kazengurutswe kuri integer.
