Nhanganyaya yezvinhu zvevharuvhu yebhora

Zvishandiso zvemavharuvhu ebhora zvinosiyana-siyana kuti zvienderane nemamiriro akasiyana ekushanda uye zvinodiwa zvemidhiya. Zvinotevera ndezvimwe zvezvinhu zvakajairika zvemavharuvhu ebhora uye hunhu hwazvo:

1. Zvinhu zvesimbi zvakakandwa

Simbi yegrey cast: yakakodzera mvura, utsi, mhepo, gasi, mafuta nezvimwe zvinoshandiswa nedhiziri PN≤1.0MPa uye tembiricha -10℃ ~ 200℃. Mhando dzinonyanya kushandiswa ndiHT200, HT250, HT300, HT350.

Simbi inonyungudika: yakakodzera mvura, utsi, mhepo uye mafuta ine simba repamusoro PN≤2.5MPa uye tembiricha -30℃ ~ 300℃. Mhando dzinonyanya kushandiswa ndiKTH300-06, KTH330-08, KTH350-10.

Ductile iron: Yakakodzera PN≤4.0MPa, tembiricha -30℃ ~ 350℃ mvura, utsi, mhepo nemafuta nezvimwe zvinoshandiswa. Magiredhi anowanzo shandiswa ndeaya: QT400-15, QT450-10, QT500-7. Pamusoro pezvo, ductile iron inodzivirira acid yakawanda yakakodzera kushandiswa kwezvinhu zvinoparadza zvine kumanikidzwa kwePN≤0.25MPa uye tembiricha iri pasi pe120℃.

2. Simbi isina ngura

Vharuvhu yesimbi isina ngura inonyanya kushandiswa mumapaipi ane simba repakati nepakati, ine simba rekudzivirira kupisa, uye inoshandiswa zvakanyanya mumaindasitiri emakemikari, petrochemical, smelting nemamwe maindasitiri. Simbi isina ngura ine simba rekudzivirira kupisa uye simba rekupisa kwakanyanya, yakakodzera mhando dzakasiyana dzezvinhu zvinoparadza uye nzvimbo dzinopisa zvakanyanya.

3. Zvinhu zvemhangura

Chiumbwa chemhangura: Chakakodzera mvura yePN≤2.5MPa, mvura yegungwa, okisijeni, mhepo, mafuta nezvimwe zvinoshandiswa, pamwe chete nekupisa kwe -40℃ ~ 250℃. Magiredhi anowanzo shandiswa ndeaya: ZGnSn10Zn2(tin bronze), H62, Hpb59-1(brass), QAZ19-2, QA19-4(aluminium bronze) nezvimwewo.

Mhangura inodziya zvakanyanya: yakakodzera zvigadzirwa zveutsi nepeturu zvine kumanikidzwa kwePN≤17.0MPa uye tembiricha ye≤570℃. Mhando dzinonyanya kushandiswa ndiZGCr5Mo, 1Cr5Mo, ZG20CrMoV nezvimwewo.

4. Simbi yekabhoni

Simbi yekabhoni yakakodzera mvura, utsi, mhepo, hydrogen, ammonia, nitrogen uye zvigadzirwa zvepeturu zvine kumanikidzwa kwePN≤32.0MPa uye tembiricha -30℃ ~ 425℃. Magiredhi anoshandiswa kazhinji ndeeWC1, WCB, ZG25 uye simbi yemhando yepamusoro 20, 25, 30 uye simbi yekuvaka yakaderera 16Mn.

5. Zvinhu zvepurasitiki

Vharuvhu yebhora yepurasitiki yakagadzirwa nepurasitiki yekugadzira zvinhu zvitsva, iyo yakakodzera kubata nzira yekufambisa nemidziyo inoparadza. Mapurasitiki anoshanda zvakanyanya akadai sePPS nePEEK anowanzo shandiswa sezvigaro zvevharuvhu yebhora kuona kuti sisitimu yacho haikanganisike nemakemikari aripo nekufamba kwenguva.

6. Zvinhu zvesimbi

Vharuvhu yebhora reCeramic rudzi rutsva rwezvinhu zvevharuvhu, ine simba rekudzivirira ngura uye kusakara zvakanaka. Ukobvu hwevharuvhu hunodarika zvinodiwa nechiyero chenyika, uye zvinhu zvemakemikari uye hunhu hwemakanika hwechinhu chikuru zvinosangana nezvinodiwa nechiyero chenyika. Parizvino, inoshandiswa mukugadzira simba remagetsi rinopisa, simbi, peturu, kugadzira mapepa, mainjiniya ezvebhayoloji nedzimwe nzvimbo.

7. Zvinhu zvakakosha

Simbi inodziya zvishoma: yakakodzera kumanikidzwa kwePN≤6.4MPa, tembiricha ≥-196℃ ethylene, propylene, gasi rechisikigo remvura, nitrogen yemvura nezvimwe zvinhu. Mhando dzinonyanya kushandiswa ndedzinoti ZG1Cr18Ni9, 0Cr18Ni9, 1Cr18Ni9Ti, ZG0Cr18Ni9 nezvimwewo.

Simbi isingapindi acid: yakakodzera nitric acid, acetic acid nezvimwe zvinoshandiswa nePN≤6.4MPa uye tembiricha ≤200℃. Mhando dzakajairika ndiZG0Cr18Ni9Ti, ZG0Cr18Ni10 (resistance of nitric acid), ZG0Cr18Ni12Mo2Ti, ZG1Cr18Ni12Mo2Ti (resistance of acid and urea) nezvimwewo.

Muchidimbu, sarudzo yezvinhu zvevharuvhu yebhora inofanira kusarudzwa zvichienderana nemamiriro chaiwo ekushanda uye zvinodiwa zvepakati kuti ive nechokwadi chekushanda kwakajairika uye kugadzikana kwenguva refu kwevharuvhu.
