Nzira Yekusarudza Sefa

1. Pasefa

Sezvinoratidzwa nezita racho, mafirita anoshandiswa kusefa zvinwiwa kana magasi uye zvimwe zvinwiwa.Basa rayo guru nderokusefa, kuitira kuti uwane chinangwa chevashandisi.

2. Pakurongeka kwemasefa

Mafirita anonyanya kuiswa muzvikamu zviviri zvinoenderana nekwazvo zvinodiwa.

1. coarse sefa, inozivikanwawo seprefilter.Musiyano mukuru ndewekuti kuita kwavo kusefa kunowanzo hukuru kupfuura 100 microns (100um kusvika 10mm…).;

2. precision sefa, inozivikanwawo sefireta yakanaka.Musiyano mukuru ndewekuti kusefa kwavo kunenge kuri pasi pe100 microns (100um~0.22um).

Zvinoenderana nezvinodiwa zvenyama, iyo sefa yakakamurwa kuita zvikamu zvitatu:

1. carbon steel zvinhu (zvakajairwa zvinhu, zvakadai seQ235., A3, 20 #, nezvimwewo), inonyanya kushandiswa kune zvinopisa zvinwiwa kana magasi uye zvichingodaro.Zvechokwadi, sesefa yezvikamu zvisina njodzi.Kazhinji inogadzirwa nesimbi isina tsvina.

2. Stainless simbi zvinhu (zvakadai 304, 316, etc.), kunyanya kushandiswa corrosive media.Mhedziso ndeyokuti zvinhu izvi zvinogona kushivirira.Iyo sefa element inogadzirwa nesimbi isina tsvina, titanium simbi kana PP.

3. PP zvinhu (zvakadai se polypropylene, polytetrafluoro, kusanganisira fluorine lining kana lining PO, nezvimwewo) inonyanya kushandiswa mumishonga yemakemikari yakadai seasidhi, alkali, munyu nezvimwe zvakadaro.Iyo sefa musimboti kazhinji ndeye polypropylene.

Zvinoenderana nezvinodiwa zvekumanikidza, sefa yakakamurwa kuita zvikamu zvitatu:

1. low pressure: 0 ~ 1.0MPa.

2. kumanikidzwa kwepakati: 1.6MPa kusvika 2.5MPa.

3. high pressure: 2.5MPa kusvika 11.0MPa.
