Mupombi pombi fittings mavharuvhu pombi uye mamwe dhizaini kana kutenga tinowanzosangana DN, masendimita ", Φ uye mamwe mayuniti, pane shamwari dzakawanda (kunyanya dzakawanda itsva kune indasitiri shangu) nokuda ichi kuvhiringidzika, havagoni kusiyanisa muenzaniso, nhasi isu ichapfupisa pfupiso yezvikamu zvitatu zvedunhu rakananga ongororo.
1.DN
"DN" shamwari zhinji dzinofunga zvisiri izvo kuti dhayamita yemukati, zvechokwadi DN uye dhayamita yemukati yevamwe vari padyo, asi padyo chete, zvarinoreva chaizvo pombi, pombi, zvigadziriso zvezita dhayamita, zita rekuti dhayamita (Nominal Diameter), inozivikanwawo se avhareji kunze dhayamita (Kureva Kunze Diameter), kutaura zvazviri, anenge avhareji kunze dhayamita.
Mumusha weDN kukosha kwakajairika zvakanyanya, asi mupombi, pombi uye mavharuvhu fittings anogona kungomiririra chikamu, nei chikamu chayo?Nekuti muhurongwa hwepombi yemumba, panogona kuve nemhando mbiri dzekunze dhayamita mune imwechete DN yakanyorwa pombi (Φ ndiyo dhayamita yekunze yepombi kana pombi, isu tichatsanangura gare gare), senge DN100, kune I akateedzana uye II akateedzana (zvakare. inobatsira kumaka A series uye B series), I series uye A series yeDN100 iri Φ114.3, ukuwo II series neB series yeDN100 iri Φ108.Kana iwe usingatsanangure dhayamita yekunze yepombi Φ mushure meDN paunenge uchiratidzira chirongwa uye ruzivo, unofanirwa kujekesa kana iri I series (A series) kana II series (B series) pakumaka neDN, kuitira kuti yakajeka mukutenga nekubvunza, uye unogona kuziva rudzi rwepombi kana kukodzera kunze kwedhayamita yaunoda pasina kutaurirana nekusimbisa.
2. masendimita
Inch" inhengo yeumambo, inonyanya kushandiswa muAmerica neEurope, iriwo chikwata, hongu, ine Pipe neTube pombi, nhasi tiri kutsanangura Pipe kirasi yemapombi uye mafittings, gare gare tichasuma, Pipe pombi uye Tube. pombi yakananga musiyano.
MuPipe pombi, inch haina kufanana neDN unit kusiyanisa dhayamita rekunze remhando mbiri dzepombi, iyuniti yakajeka, senge 4 ″ yakanyatso ratidza kuti dhayamita rekunze 114.3, uye 10 ″ iri Φ273, sekureba iyo pombi kana zvigadzirwa zvinotsanangurwa ne inch zvinogona kunyatsozivikanwa pasina kusimbiswa kwepombi inodiwa yekunze dhayamita saizi.
3. Diameter Φ
Chiratidzo chedhayamita ndi“Φ”, chinova chebhii rechiGiriki, chinodaidzwa kuti “fai”, uye chine hukama hwepedyo neaya maviri apfuura, nekuti chinogona kutsiva mayunitsi maviri ari pamusoro apa, uye pombi kana pombi inoshandisa Φ ndiyo yakanyanya kujeka, uye ndiyo yakanyanya kunanga pasina kutendeuka, senge Φ219, Φ508, Φ1020, zvichingodaro. Iyi nzira yekuzivisa zvakare yakakura.
