Nceda qaphela:

(1) Iigasket ze-EPDM azifanele zidibane nezinyibilikisi ezinuka kamnandi ngaphezulu kwesiqingatha seyure.

(2) Icala elingasemva lepleyiti alinakuchukumisa umhlaba ngqo xa licocwa.

(3) Emva kokucoca ngamanzi, jonga ngononophelo iipleyiti kunye neegasket kwaye akukho ntsalela efana namasuntswana aqinileyo kunye neefayibha ezishiyekileyo kumphezulu wepleyiti ezivumelekileyo. Igasket exotyulweyo neyonakeleyo kufuneka incamathiselwe okanye itshintshwe.

(4) Xa kucocwa ngoomatshini, akuvumelekanga ukusebenzisa ibrashi yesinyithi ukunqanda ukukrwela ipleyiti kunye negasket.

(5) Xa kucocwa ngesibhamu samanzi esinoxinzelelo oluphezulu, ipleyiti eqinileyo okanye ipleyiti eqinisiweyo kufuneka isetyenziswe ukuxhasa icala elingasemva lepleyiti (le pleyiti mayidibane ngokupheleleyo nepleyiti yokutshintshiselana ngobushushu) ukuthintela ukuguguleka, umgama phakathi kwe-nozzle kunye nepleyiti yokutshintshiselana ngobushushu akufuneki ube ngaphantsi kwe-200 mm, uxinzelelo oluphezulu lwe-injection alukho ngaphezu kwe-8Mpa; Okwangoku, ukuqokelelwa kwamanzi kufuneka kuthathelwe ingqalelo ukuba usebenzisa isibhamu samanzi esinoxinzelelo oluphezulu ukuthintela ukungcoliswa kwindawo kunye nezinye izixhobo.

2  Ukucoca ngamakhemikhali

Kwi-fouling eqhelekileyo, ngokweempawu zayo, i-alkali agent enobunzima obungaphantsi okanye obulingana ne-4% okanye i-asidi agent enobunzima obungaphantsi okanye obulingana ne-4% ingasetyenziselwa ukucoca, inkqubo yokucoca yile:

(1) Ubushushu bokucoca: 40 ~ 60 ℃.

(2) Ukuhlamba umqolo ngaphandle kokuqhaqha izixhobo.

a) Qhagamshela umbhobho kwindawo yokungena kunye nendawo yokuphuma kwangethuba;

b) Qhagamshela izixhobo "nesithuthi sokucoca oomatshini";

c) Pompa isisombululo sokucoca kwizixhobo kwicala elichaseneyo njengoko imveliso isetyenziswa rhoqo;

d) Jikelezisa isicoci sokucoca imizuzu eli-10 ukuya kweli-15 ngesantya sokuhamba kwemidiya esiyi-0.1 ~ 0.15m/s;

e) Ekugqibeleni phinda ujikeleze amanzi acocekileyo imizuzu emi-5 ukuya kweli-10. Umxholo wekloridi emanzini acocekileyo mawube ngaphantsi kwe-25ppm.

Nceda qaphela:

(1) Ukuba le ndlela yokucoca iyasetyenziswa, uqhagamshelo oluseleyo luya kuhlala ngaphambi kokuba luhlanganiswe ukuze ulwelo lokucoca lukhutshwe kakuhle.

(2) Amanzi acocekileyo aza kusetyenziselwa ukuhlamba i-heat exchanger ukuba i-back flush yenziwe.

(3) Isixhobo sokucoca esikhethekileyo siya kusetyenziselwa ukucoca ukungcola okukhethekileyo ngokusekelwe kwiimeko ezithile.

(4) Iindlela zokucoca ngoomatshini nangeekhemikhali zingasetyenziswa kunye.

(5) Nokuba yeyiphi na indlela eyamkelweyo, i-hydrochloric acid ayivumelekanga ukucoca ipleyiti yentsimbi engagqwaliyo. Amanzi angaphezulu kwe-25 ppm chlorion content awanakusetyenziselwa ukulungisa ulwelo lokucoca okanye ipleyiti yentsimbi engagqwaliyo egutyungelweyo.
