Ka hopena o ka hāmare wai o ka valve Hoʻokomo i ke kumu a me ka hoʻonā o ka overload o ka valve electric actuator! ʻO ka "Water Hammer Effect" e pili ana i ka wā e pani koke ʻia ai ka pahu hāmama, ma muli o ka inertia o ke kaomi Kahe wai, e hana ʻia ka nalu haʻalulu wai a hana ʻia nā pōʻino. ʻO kēia ka "Water hammer effect" i loko o ka hydrology, i ʻike ʻia ʻo ka hammer Wai maikaʻi. ʻO ka mea ʻē aʻe, ma hope o ka wehe koke ʻia ʻana o ka pahu paʻa, e hana pū ia i ka hāmare wai, i kapa ʻia ʻo ka hāmare wai maikaʻi ʻole, a aia kekahi haʻihaʻi Wai Hammer Effect E pili ana i ka wā e pani koke ʻia ai ka pahu hāmama, ma muli o ka inertia o ke kaomi. kahe wai, e hana ʻia ka nalu haʻalulu o ke kahe wai, a e hana ʻia ka hopena luku. ʻO kēia ka "hopena hāmare wai" ma ka hydrology, ʻo ia ka hāmare wai maikaʻi. ʻO ka mea ʻē aʻe, ma hope o ka wehe koke ʻia ʻana o ka pahu i pani ʻia, e hana pū ia i ka hāmare wai, i kapa ʻia ʻo ka hāmare wai maikaʻi ʻole, nona kekahi mana luku, ʻaʻole naʻe e like me ka mua. ʻO ka maʻamau, huki koke ʻia ka mea pani i loko o ka noho i ka wā e kokoke mai ana ka pahu e pani, ʻike ʻia ʻo ka hopena latching cylinder solution. Hoʻokumu ʻia ka hopena latching cylinder e kahi mea hoʻokele haʻahaʻa haʻahaʻa ʻaʻole lawa ka pahu e noho kokoke i ka noho, ka hopena i ka pani koke ʻana o ka pamu a i ʻole ka valve, e hopena i ka hopena hāmare wai. No nā kī kī, i kekahi mau hihia, hiki i nā hiʻohiʻona kahe wikiwiki ke alakaʻi i ka hopena hammer wai. ʻOiai ke kani nui nei ka hāmare wai, ʻo ka pōʻino maoli ke kumu o ka hemahema mechanical. Ma muli o ka hoʻololi wikiwiki ʻana mai ka ikehu kinetic a hiki i ke kaomi laina static, hiki i ka hāmare wai ke haki i ka laina a i ʻole e hōʻino i ke kākoʻo paipu a hōʻino i ka hui laina. No nā valve, hiki i ka hāmare wai ke hoʻoulu i ka haʻalulu nui ma o ka spool, hiki ke hoʻopau i ka spool, gasket a i ʻole ka hoʻopili ʻana. No nā kiwikā, ʻo ka pale ʻana i ka hāmare wai ka mea e pale ai i ka hoʻololi koke ʻana o ka ʻōnaehana. Hoʻopili kēia i ka hoʻolōʻihi ʻana i ka pani ʻana o ka valve ponoʻī a i ʻole ka hāʻawi ʻana i kahi kiʻekiʻe o ka haʻalulu a me ka paʻakikī i ka wā e hoʻokokoke ai ka mea pani i ka noho. No ka pale ʻana i ka loli ʻana o ke kaomi, pono e pani ʻia ka valve me ka wikiwiki like. I kekahi mau hihia, i ka hoʻohana ʻana i ka hiʻohiʻona wehe wikiwiki, hiki iā ʻoe ke noi no ka hoʻololi ʻana i ka hiʻohiʻona like. No nā kīwi hoʻomalu e pono e hoʻopaʻa ʻia i ka wā kokoke i ka noho, pono e hoʻohana ʻia nā mea hoʻokele me ka nui o ka hoʻokuʻu ʻana, e like me nā piston pneumatic actuators a i ʻole hydraulic actuators, a i ʻole nā notches kūikawā ma ka lima hahau o nā mea hoʻokele lima e hōʻemi a pale i ka laka cylinder. Hiki i kekahi ʻano pale anti-wave ma ka ʻōnaehana paipu ke hōʻemi i nā hama wai. Hiki ke hana i kēia me ka hoʻohana ʻana i ka pahu hoʻomaha kaomi a i ʻole ka pahu pale. Eia kekahi, hiki ke hoʻokomo ʻia ke kinoea i loko o ka ʻōnaehana, e hōʻemi ana i ka nui o ka wai a hāʻawi i kahi compressibility e mālama i nā loli koke. ʻO Valve electric actuator overload kumu a me nā hoʻonā! ʻO nā kumu nui o ka mea hoʻokele uila Valve: ʻo ka mea mua, he haʻahaʻa ka mana o ka mana, ʻaʻole ka torque i koi ʻia, no laila e pau ka holo ʻana o ke kaʻa; ʻO ka lua, he hewa ka hoʻoponopono ʻana i ka mīkini palena torque, i ʻoi aku ka nui ma mua o ka torque i hoʻōki ʻia, ka hopena i ka hoʻomau ʻana i ka torque kiʻekiʻe, i pau ai ke kaʻa kaʻa; ʻEkolu ka hoʻohana manawaleʻa, ka mālama ʻana i ka wela, ʻoi aku ma mua o ke kaʻa i ʻae ʻia. ʻO ka lua, he hewa ka hoʻoponopono ʻana i ka mīkini palena torque, i ʻoi aku ka nui ma mua o ka torque i hoʻōki ʻia, ka hopena i ka hoʻomau ʻana i ka torque kiʻekiʻe, i pau ai ke kaʻa kaʻa; ʻEkolu ka hoʻohana manawaleʻa, mālama i ka wela, ʻoi aku ma mua o ka piʻi ʻana o ka mahana o ke kaʻa; ʻO ka hā, no kekahi kumu, ʻaʻole hiki ke hoʻokaʻawale ʻia ka torque limiting mechanism, no laila ua nui loa ka torque; ʻO ka lima, ʻoi aku ka kiʻekiʻe o ka hoʻohana ʻana i ka wela ambient, e pili ana i ka emi ʻana o ka hikina wela. I ka wā ma mua, ua hoʻohana ʻia nā fuses, overcurrent relays, thermal relays a me thermostats no ka pale ʻana i nā kaʻa, akā he mau pono a me nā hemahema kēia mau ʻano. ʻAʻohe ala palekana a hilinaʻi hoʻi e pale aku i nā mea uila me ka ukana loli. No laila, pono e lawe i nā ʻano hui like ʻole, i hōʻuluʻulu ʻia ma nā ʻano ʻelua: ʻo ka hoʻoholo ʻana i ka hoʻonui a i ʻole ka emi ʻana o ka hoʻokomo ʻana i kēia manawa; ʻO ka lua, ʻo ia ka hoʻoponopono ʻana i ke kaʻa ponoʻī. ʻO kēia mau ala ʻelua, ʻaʻohe mea e noʻonoʻo ai i ka mana wela kaʻa i hāʻawi ʻia i ka palena manawa. Ma keʻano laulā, ʻo ka pale kumu no ka overload ʻo ia: 1. No ka hana mau ʻana a i ʻole ka hana kiko o ka pale overload, me ka hoʻohana ʻana i ka thermostat; 2. Hoʻohana ʻia ka relay wela no ka pale ʻana i nā kaʻa; 3. No ka ulia kaapuni pōkole, e hoʻohana i ka fuse a i ʻole relay overcurrent. ʻO Valve electric actuator kahi mea pono loa e ʻike ai i ka mana o ka polokalamu valve, ka mana a me ka mana mamao. Hiki ke ho'omalu 'ia kona ne'e 'ana e ka hahau, torque a i 'ole axial thrust. He mea nui ke koho pololei ʻana i ka mea uila valve no ka pale ʻana i ka overload phenomenon (ʻoi aku ka kiʻekiʻe o ka torque hana ma mua o ka control torque).
