Mai ka papalua o ka liʻiliʻi liʻiliʻi a me ka hoʻopaʻa ʻia ʻana, ʻaʻole maikaʻi ka hoʻopaʻa paʻa ʻana. E like me ka hana piha o ka pahu kukui ultra, i hoʻopaʻa ʻia a hoʻopaʻa ʻia me ka pale ʻana i ke alo o ka lole, ka hilinaʻi kiʻekiʻe, ka leakage rate o 10-7, ua hiki ke hoʻokō i nā koi o ka ʻoki ʻoki. 2, no ke aha e hiki ʻole ai ke hoʻohana ʻia i ka valve seal pālua e like me ka valve ʻoki ʻia? ʻO ka pōmaikaʻi o ka spool valve ʻelua noho ʻana ʻo ia ka hoʻolālā ʻana o ka ikaika, e ʻae ana i ka ʻokoʻa o ke kaomi nui, a ʻo kona hemahema koʻikoʻi ʻaʻole hiki ke hoʻopili maikaʻi ʻia nā papa hoʻopaʻa ʻelua i ka manawa like, e hopena i ka leakage nui. Inā hana ʻia, koi ʻia no ka ʻoki ʻana i nā manawa, ʻike maopopo ʻole ʻaʻole maikaʻi ka hopena, ʻoiai inā ua hana ʻo ia i nā hoʻomaikaʻi he nui (e like me ke kīpē lima sealing pālua), ʻaʻole makemake ʻia. 3. No ke aha i maʻalahi ai ka hoʻololi ʻana o ka valve noho ʻelua i ka wā e hana ai me ka wehe liʻiliʻi? No ke kumu hoʻokahi, i ka wā e wehe ʻia ai ke ʻano kahe kahe, maikaʻi ke kūpaʻa valve; Ke pani ʻia ke ʻano waena, ʻilihune ka paʻa o ka valve. ʻO ka valve noho ʻelua he ʻelua spool, ʻo ka spool haʻahaʻa i loko o ke kahe i pani ʻia, ʻo ka spool luna i loko o ke kahe hāmama, no laila, i ka hana wehe liʻiliʻi, ua maʻalahi ke kahe i pani ʻia e hana i ka haʻalulu o ka valve, kēia. ʻo ia ke kumu i hiki ʻole ai ke hoʻohana ʻia ka valve noho ʻelua no ka hana wehe liʻiliʻi. 4, he aha ka maikaʻi o ka hoʻokō ʻana i ka hana hoʻopā pololei, ʻo ka hana ʻana i ka hana hoʻopaʻa ʻana i ke kīpē pololei? ʻO ke kuʻekuʻe kuʻekuʻe ʻana o ke kīpē polopololei, a ʻo ke ʻano o ke kahe ʻana i loko a i waho o ka pahu kahe o ke keʻena valve pono e huli, no laila ua paʻakikī loa ke ala kahe o ka valve (ke ʻano e like me ke ʻano S inverted). Ma kēia ala, nui nā ʻāpana make, e hāʻawi ana i kahi no ka ua o ka waena, kahi, i ka wā lōʻihi, e hoʻopili ai. ʻO ka angle stroke valve throttling direction ʻo ia ka ʻaoʻao ākea, kahe ākea i loko o ka waena, kahe ʻana i waho, maʻalahi ka lawe ʻana i ke ʻano lepo lepo, i ka manawa like he maʻalahi ke ala kahe, liʻiliʻi loa ka nui o ka ua, no laila ke kāohi nei ka Angle stroke valve. maikaʻi ka hana. 5, no ke aha i ʻoi aku ka lahilahi o ka ʻōpala hoʻoponopono pololei? ʻO ke kīpē hoʻoponopono pololei e pili ana i kahi loina mechanical maʻalahi: sliding friction, rolling friction liʻiliʻi. ʻO ka neʻe ʻana i luna a iho i lalo, e hoʻopaʻa liʻiliʻi, e hoʻokomo i ka pūʻolo kumu i paʻa loa, e hopena i kahi ʻokoʻa nui. I kēia hopena, he liʻiliʻi loa ka hoʻolālā kumu, a hoʻohana pinepine ʻia ka paʻi ʻana me ka liʻiliʻi friction coefficient o ka ptfe packing, i mea e hōʻemi ai i ka hoʻihoʻi ʻokoʻa, akā ʻo ka pilikia ʻo ia ka lahilahi, maʻalahi ke kulou, a me ke ola. pōkole o ka paʻi ʻana. No ka hoʻoponopono ʻana i kēia pilikia, ʻo ke ala maikaʻi loa ʻo ka hoʻohana ʻana i ke ʻano o ka pahu pahu rotary, ʻo ia hoʻi, ʻO ke ʻano o ka angle stroke o ka hoʻoponopono valve, ʻo kona kumu ma mua o ka ʻōpala pololei ʻana i ka mānoanoa 2 ~ 3 mau manawa, a koho i ke ola lōʻihi o ka graphite packing, ʻo ka ʻoʻoleʻa kumu maikaʻi, packing. lōʻihi ke ola, liʻiliʻi ke kua o ka friction, liʻiliʻi ke kua. 6, no ke aha i ʻoki ʻia ai ka ʻokoʻa ʻokoʻa o ka Angle stroke? ʻOi aku ka nui o ka pāpaʻi i loko o ka spool a i ʻole ka pā pāpaʻi ma ka torque hopena i hana ʻia e ka ʻauʻau wili, no laila, hiki iā ia ke pale i ka ʻokoʻa ʻoi aku ka nui. 7. No ke aha i hoʻololi ai ka pahu lima lima i ka valve noho hoʻokahi a me ka lua? ʻO ka hiki ʻana mai o ka pahu lima lima i ka makahiki 1960, i ka makahiki 1970 i ka nui o ka hoʻohana ʻana i ka home a me ka ʻāina ʻē, ʻo ka hoʻokomo ʻana i nā mea hana petrochemical i ka makahiki 1980s lima lima i helu ʻia no ka nui o ka lakio, i kēlā manawa, manaʻo nui ka poʻe e hiki i ka pahu lima lima. hoʻololi i ka pahu hoʻokahi, noho pālua, lilo i ka lua o ka hanauna o nā huahana. I kēia lā, ʻaʻole kēia ka hihia, hoʻohana ʻia nā valve noho hoʻokahi, nā pahu noho ʻelua, nā pulima lima. ʻO kēia no ka mea, ʻoi aku ka maikaʻi o ka pahu lima lima i ke ʻano throttling, kūpaʻa a me ka mālama ʻana i ʻoi aku ka maikaʻi ma mua o ka pahu noho hoʻokahi, akā ʻo kona paona, ka pale ʻana a me ka leakage nā hōʻailona a me ka pahu hoʻokahi, pālua noho, pehea lā e hiki ai ke hoʻololi i ka pahu hoʻokahi noho pālua? No laila, hiki ke hoʻohana pū wale ʻia. 8, no ke aha ka hoʻohana ʻana i ka wai desalination me ka lāʻau lapaʻau i hoʻopaʻa ʻia i ka pahu lele, ka fluorine i hoʻopaʻa ʻia i ka diaphragm valve pōkole ola? Aia i loko o ka wai desalinated ka ha'aha'a ha'aha'a o ka waikawa a i'ole ka alkali, a 'oi aku ka nui o ka poino i ka lā'au. Hōʻike ʻia ka corrosion o ka lāʻau e like me ka hoʻonui ʻana, ka ʻelemakule, ka ikaika haʻahaʻa, a me ka hopena o ka hoʻohana ʻana i ka valve butterfly a me ka valve diaphragm i hoʻopaʻa ʻia me ka ʻōpala he ʻilihune, a ʻo kona ʻano kumu ke kumu o ka pale corrosion. Ma hope o ka hoʻomaikaʻi ʻana i ka valve diaphragm i hoʻopaʻa ʻia i ka valve fluorine lined diaphragm valve me ka pale ʻana i ka corrosion maikaʻi, akā ua haki ka diaphragm o ka fluorine lined diaphragm valve ma ka pelu ʻana i luna a i lalo, e hopena i ka pōʻino mechanical, a ua pōkole ke ola o ka pahu. I kēia manawa, ʻo ke ala maikaʻi loa e mālama ai i ka valve pōpō me ka wai, hiki ke hoʻohana ʻia no 5 ~ 8 mau makahiki. 9. No ke aha i hoʻohana nui ʻia ai nā mea hoʻokele piston i nā kiwi pneumatic? No nā valve pneumatic, hiki i ka piston actuator ke hoʻohana piha i ke kaomi kumu ea, ʻoi aku ka paʻakikī o ka mea hana ma mua o ke ʻano kiʻiʻoniʻoni, ʻoi aku ka nui o ka pahu, ʻoi aku ka hilinaʻi o ka o-ring i ka piston ma mua o ke kiʻiʻoniʻoni, no laila e oi aku ana kona hoohana ana. 10. No ke aha i ʻoi aku ka nui o ke koho ʻana ma mua o ka helu? He mea nui a paʻakikī ka helu ʻana ma mua o ke koho. No ka mea ʻo ka helu ʻana he helu maʻalahi wale nō ia, ʻaʻole hilinaʻi ʻo ia iho i ke degere o ke ʻano, akā ma ka pololei o nā ʻāpana kaʻina i hāʻawi ʻia. ʻO ke koho e pili ana i nā ʻike hou aʻe, ʻaʻole mālama iki, e alakaʻi i ke koho kūpono ʻole, ʻaʻole wale ke kumu o ka hoʻopau ʻana i nā waiwai kanaka, nā waiwai a me nā waiwai kālā, akā ʻaʻole kūpono hoʻi ka hoʻohana ʻana i ka hopena, e lawe mai ana i nā pilikia hoʻohana, e like me ka hilinaʻi. , ola, maikaʻi hana a pēlā aku.
