He aha ka ʻōpala o ke kāʻei piston ring kaʻa
ʻO ka ʻōpala ʻana o ke kāʻei piston apo kaʻa e pili ana i ke kau ʻana i ke apo piston i loko o kahi pahu ʻōpala kikoʻī e pale aku iā ia mai ka hōʻino ʻana a maʻalahi i ka lawe ʻana a me ka mālama ʻana. ʻO nā ʻano ʻōpala maʻamau e komo pū me ka ʻōpala ʻeke plastik, ka ʻōpala pahu a me ka ʻōpala pahu hao.
Nā ʻano hoʻopili maʻamau a me ko lākou mau ʻano
ʻeke palakika : He maʻalahi kēia ʻano ʻeke, noho i kahi liʻiliʻi, hiki ke pale pono i ka popo o ke apo piston. Eia nō naʻe, ʻaʻole nani ka apo piston o ka ʻeke palakika, a e uhi kekahi mau mea hana i waho me kahi papa o ka pahu pepa a i ʻole ka pepa kraft .
ʻūpā pahu : he nani ke ʻano o ka pahu, maʻalahi ke lawelawe, hiki ke hōʻailona maʻalahi. Ma mua o ka ʻūpā ʻana, e pīpī pū kekahi mau mea hana i ka uhi anti-oxidation ma luna o ka ʻili o ke apo piston e hoʻolōʻihi i kona ola lawelawe. Hiki i ka ʻūpā pahu ke lilo i ʻūpā lua o ke apo piston e pale aku i ka friction .
ʻO ka hoʻopili ʻana i ka pahu hao: hoʻohana pinepine ʻia ka hana tinplate, ʻo kēia ʻano hoʻopili kiʻekiʻe a me ka pale makū, hiki ke hoʻokaʻawale pono i ka makū, pale i ke apo piston.
ʻIke kumu e pili ana i nā apo piston
Hoʻokomo ʻia ke apo Piston i loko o ke awāwa piston i loko o ke apo metala, i māhele ʻia i ke apo compression a me ke apo aila ʻelua. Hoʻohana ʻia ke apo compression e sila i ka hui ʻana o ke ahi i loko o ke keʻena kuni, ʻoiai hoʻohana ʻia ke apo aila e ʻeli i ka aila keu mai ka cylinder. ʻO ke apo Piston kahi ʻano apo elastic metala me ka deformation hoʻonui nui i waho, e hilinaʻi ana i ka ʻokoʻa o ke kaomi o ke kinoea a i ʻole ka wai e hana i kahi sila ma waena o ka pōʻai waho o ke apo a me ka cylinder, a ma waena o ke apo a me ke awāwa apo.
ʻO nā hana palekana o ke kau ʻana i ke apo piston kaʻa e komo pū ana me kēia mau mea:
E hōʻoia i ka waiho pono ʻana o ke apo piston i loko o ka liner cylinder, a mālama i kahi ākea kūpono ma ka interface, kahi i ʻōlelo ʻia e hoʻomalu ʻia ma ka pae o 0.06-0.10mm. Hiki i kēia ke hōʻoia ʻaʻole e hoʻopuka ka apo piston i ka nui o ka friction a me ka ʻaʻahu ma muli o ka liʻiliʻi o ka ākea.
Pono e kau pono ʻia ke apo piston ma luna o ka piston, a e hōʻoia i ka loaʻa ʻana o kahi ʻaoʻao kūpono ma ke kiʻekiʻe o ke awāwa apo, i ʻōlelo ʻia e mālama ma waena o 0.10-0.15mm. Hiki i kēia ke hōʻoia ʻaʻole e paʻa ke apo piston ma muli o kahi hakahaka liʻiliʻi loa a i ʻole ka leaka ma muli o kahi hakahaka nui loa.
Pono e hoʻokomo ʻia ke apo chrome ma ke kūlana mua, a ʻaʻole pono e kū pono ka puka i ka lua o ke au eddy ma luna o ka piston. E hōʻemi kēia i ke komo ʻana a me ka haehae ʻana ma ka hana.
Pono e hoʻokaʻawale ʻia nā puka o nā apo piston he 120 degere mai kekahi i kekahi a ʻaʻole pono e kūlike me nā lua pine piston. Pale kēia i ka haʻalulu a me ke komo hou ʻana o ke apo piston i ka wā o ka hana.
I ke kau ʻana i ke apo piston ʻāpana cone, pono e kū pono ka maka cone i luna. No ke kau ʻana i ke apo torsion, pono e kū pono ka chamfer a i ʻole ke groove i luna. I ke kau ʻana i ke apo hui pū ʻia, e hoʻokomo mua i kahi apo lining axial, a ukali ʻia e kahi apo pālahalaha a me kahi apo corrugated, a pono e hoʻokaʻawale ʻia nā puka o kēlā me kēia apo.
I ka wā e hoʻouka ai, e mālama i ka ʻili pili ma waena o ke apo piston a me ka liner cylinder i maʻemaʻe e pale aku i nā mea haumia a me ka lepo. Ma hope o ke kau ʻana, e nānā inā ua like ka ʻili pili ma waena o ke apo piston a me ka liner cylinder i mea e pale aku ai i ka palupalu a paʻa loa .
E hoʻohana i nā mea hana kūikawā e hoʻokomo ai, e like me nā pliers hui kūikawā no nā apo piston, nā lima cone, a pēlā aku. Hoʻemi kēia i ka pilikia o ka hōʻino ʻia ʻana o ke apo piston a i ʻole ke ʻano ʻē ma muli o ka hoʻonui nui ʻia.
Inā makemake ʻoe e ʻike hou aku, e hoʻomau i ka heluhelu ʻana i nā ʻatikala ʻē aʻe ma kēia pūnaewele!
E ʻoluʻolu e kelepona mai iā mākou inā makemake ʻoe i kēlā mau huahana.
ʻO Zhuo Meng Shanghai Auto Co., Ltd. ua kūpaʻa i ke kūʻai aku ʻana i nā ʻāpana kaʻa MG&750 e kūʻai.
