ʻO nā mea hoʻoheheʻe PTFE

Hiki ke loaʻa nā ʻāpana bearing i ka hoʻokomo ʻana ma o ka bolting, tack-weld, full welding or mortar embedment, a ʻo ke ʻano kūpono o ka bearing e koho ʻia e like me ke ʻano hoʻonohonoho.Pono e pale pono ʻia ka PTFE mai ka weld spatter, paint spray, metala swarf etc, i ka wā e kau ai.

Ma kahi ākea o nā noi, ʻoi aku ka maikaʻi o nā bearings PTFE Slide ma mua o nā papa hoʻonui maʻamau, nā wili a me nā kākoʻo lima rocker.Kākoʻo lākou i nā mea kanu petrokimia, nā mīkini kaumaha, nā paipu, nā hale a me nā ʻāpana alahaka;hoʻokomo lākou i ka hoʻonui ʻana, ka ʻokiʻoki a me nā neʻe pānaʻi ʻē aʻe o kēlā me kēia hale e neʻe ana ma muli o nā ikaika wela, seismic a ʻokoʻa paha.

Pono e hana nā bearings no ia mau noi i nā haʻahaʻa kiʻekiʻe a me nā wikiwiki haʻahaʻa, a aia ma lalo o kēia mau kūlana i ka nui o nā waiwai lubricating ponoʻī o PTFE.ʻO kēia kumu, me kona ʻano lāʻau ʻole a me nā hiʻohiʻona anti-weathering, ʻo ia ke kumu kumu i hōʻike ʻia ai ka PTFE e kūleʻa loa e like me ka mea lawe paheʻe.

Pono

1 ʻO ka maʻalahi o ka hoʻolālā bearing a me ka maʻalahi o ka hana ʻana a me ka hoʻokomo ʻana e hoʻemi i ke kumu kūʻai o ka ʻāpana. ʻO nā kūlana maikaʻi loa. 4 ʻAʻole mālama ʻia nā bearings - ʻo PTFE ka mea hoʻomaʻamaʻa ponoʻī iā ia iho, ʻoiai ua komo nā ʻāpana lepo i loko o ka mea.ʻO ka pale maʻalahi wale nō ke koi ʻia mai ka komo nui ʻana o ka lepo.

Coefficients o ka Friction

ʻO ke koena o ka friction o nā mea PTFE e hilinaʻi ʻia i nā ʻano like ʻole, me ke kaomi, ka wikiwiki a me ka mahana.Hoʻokaʻawale ʻia ka manaʻo e pili ana i ka hopena o kekahi mau mea hoʻololi, ʻoiai ua ʻae ʻia ʻo ke kaomi kiʻekiʻe a me ka wikiwiki haʻahaʻa e makemake i ka friction haʻahaʻa.

ʻOi aku ka liʻiliʻi ma mua o nā mea ʻenehana paʻa ʻē aʻe.Ua hōʻike like ʻia mai ka 0.02 a i ka 0.2, akā pili kēia i ka hoʻomākaukau ʻana o ka ʻili a me ke ʻano hoʻāʻo.Hōʻike ka palapala hoʻouka / friction i ka hopena o ka ukana.

Ma keʻano laulā, ʻoi aku ka liʻiliʻi o ka coefficient o friction ma waena o ka ili a me ka PTFE slide bearing pad i ka wā o ke koʻikoʻi i loko o ka PTFE i ka palena kiʻekiʻe (kūlike me nā palena ʻae ʻia o ka kolo), hana ʻia ka bearing mai ka PTFE i hoʻopiha ʻole ʻia, a ʻO ka pau ʻana o ka ʻili hoʻoheheʻe ʻia ʻoi loa.

Eia kekahi, ʻo kekahi o nā hiʻohiʻona nui o ka PTFE ʻo ka nele o ka 'stick-slip', no ka mea, ʻaʻole like me nā bearings maʻamau, ua like ka friction static o PTFE a i ʻole marginally kiʻekiʻe ma mua o ka friction ikaika.
