Metric vs BSP na'ura mai aiki da karfin ruwa Zaren: 5 Dubawa Kafin Ka yi oda

Ƙungiyar ƙira ta taɓa amincewa da zane mai yawa tare da tashoshin G1/4 a gefe ɗaya da tashar jiragen ruwa na M14x1.5 a ɗayan. Dukansu sun yi kama da daidaitattun zaren ruwa na ruwa. Mai siyarwar ya aika da adaftar alamar 'metric/BSP mai musanya.' A lokacin ƙaddamarwa, kowane haɗin gwiwa na biyu yana kuka mai. Batch ya dawo. Wannan kuskuren shine yasa injiniyoyin  Ruihua Hardware  suke gudanar da cak guda biyar kafin kowane zaren ya bayyana akan BOM. Anan ga abin da ma'auni vs BSP zaren hydraulic a zahiri ya bambanta, da kuma yadda ake dakatar da dawowar iri ɗaya.

1. Zaren layi ɗaya ko zaren da aka ɗaure

Tashoshin awo na ISO 9974 da DIN 3852 suna amfani da zaren layi ɗaya. BSP yana da fuskoki guda biyu: BSPP (G) yana layi ɗaya, yayin da BSPT (R) aka buga. Namijin da aka ɗora zai fara zuwa tashar jiragen ruwa mai kama da juna, kuma mai haɗawa yana iya jujjuya shi zuwa ƙimar zane kafin faɗuwar ya nuna. Bincika alamar zare a kowane kiran tashar jiragen ruwa. Idan zanen ya ce 'BSP' ba tare da kari na P ko T ba, tsayawa kuma tabbatar.

2. Inda hatimi ke zaune a zahiri

Wani ma'auni na O-ring na namiji yana hatimi a kan madaidaicin fuskar tashar jiragen ruwa tare da kama wani elastomer a cikin tsagi. BSPP hatimi tare da mai ɗaure mai wanki ko hatimi mai laushi ƙarƙashin hex. BSPT hatimi a kan gefen zaren. Daidaitawar da ta juya cikin yardar kaina zuwa ma'auni biyu na iya hatimi a cikin babu ɗayansu. Lokacin da ma'aunin O-ring tashar jiragen ruwa dole ne ya hadu da ƙarshen namiji na BSP,  Ruihua Hardware  yana ba da 1EZ metric namiji O-ring / BSP adaftar namiji  don haka kowane zaren yana kiyaye hanyar rufe kansa.

3. Pitch da diamita sun fi kusa fiye da yadda kuke zato

G1/4 da M14x1.5 ba iri ɗaya bane, amma G1/8 da M10x1 suna kusa da farawa da hannu. Wannan shine hatsarin. Zaren suna shiga, don haka gwajin benci yayi kyau. Auna farar tare da ma'aunin zaren kuma kirga zaren sama da mm 10 kafin zanen ya bar ofis. Kar a amince da wasan gani.

Tashar tashar O-ring mai ma'auni tana buƙatar abin ƙira don zoben O da ƙayyadadden ƙayyadaddun haɗin zaren. Tashar jiragen ruwa ta BSP tana buƙatar ƙasa mai zurfi amma bugu daban don mai wanki mai ɗaure. Matsayin musanyawa ba tare da sabunta shirin na'ura mai yawa ba yana barin ko dai dakataccen hatimi ko zaren mai gudana kyauta.  Ruihua Hardware  yana ba da shawarar aika zanen tashar jiragen ruwa don dubawa a duk lokacin da ƙira ta ketare daga awo zuwa BSP.

5. Ma'auni ɗaya a kowace kewaye

Gyara mafi arha kuma shine mafi dogaro: zaɓi tsarin zare guda ɗaya a kowane da'irar ruwa. Idan sauran injin ɗin shine ISO 9974 metric, tsara tashar tashar BSP.
