ʻElua-ʻaoʻao pahu pahu solenoid valve DHF08-241

I ka ʻōnaehana hydraulic, no kekahi kumu, piʻi koke ka piʻi ʻana o ka wai i kekahi manawa, e hopena i kahi kiʻekiʻe kiʻekiʻe. Ua kapa ʻia kēia ʻano ʻano haʻalulu hydraulic.

1. Nā kumu o ka ha'alulu hydraulic (1) ka ha'alulu hydraulic ma muli o ka pani koke 'ana o ka valve.

E like me ka mea i hōʻike ʻia ma ka Figure 2-20, aia kahi lua nui (e like me ka hydraulic cylinder, accumulator, etc.) e kamaʻilio me ka pipeline me ka valve K ma kekahi ʻaoʻao. Ke wehe ʻia ka valve, kahe ka wai i loko o ka paipu. Ke pani koke ʻia ka pahu, hoʻololi koke ʻia ka ikehu kinetic wai i ʻāpana ikehu kaomi ma ka papa mai ka valve, a hoʻokumu ʻia kahi hawewe haʻalulu kiʻekiʻe mai ka valve a i ka lua. Ma hope o ia mea, ua hoʻololi ʻia ka ikehu puʻe wai i ʻāpana ikehu kinetic ma ka papa mai ke keʻena, a kahe ka wai i ka ʻaoʻao ʻē aʻe; A laila, hoʻololi hou ʻia ka ikehu kinetic o ka wai i ka ikehu puʻe e hana i kahi hawewe haʻalulu kiʻekiʻe, a hoʻololi hou ʻia ka hoʻololi ʻana o ka ikehu i mea e hana ai i ka oscillation puʻe i ka pipeline. Ma muli o ka mana o ka friction i ka wai a me ka elastic deformation o ka pipeline, e nalo mālie ke kaʻina oscillation a paʻa.

2) ʻO ka hopena hydraulic ma muli o ka haʻalulu koke a i ʻole ka hoʻohuli ʻana i nā ʻāpana neʻe.

Ke pani koke ka pahu hoʻohuli i ke ala hoʻihoʻi aila o ka cylinder hydraulic a wāwahi i nā ʻāpana neʻe, e hoʻololi ʻia ka ikehu kinetic o nā ʻāpana neʻe i kēia manawa i ka ikehu kaomi o ka ʻaila i pani ʻia, a piʻi nui ke kaomi, e hopena. i ka hopena hydraulic.

(3) ka hopena hydraulic i hoʻokumu ʻia e ka hana ʻino a i ʻole insensitivity o kekahi mau mea hydraulic.

Ke hoʻohana ʻia ka valve hoʻomaha e like me ka valve palekana i loko o ka ʻōnaehana, inā ʻaʻole hiki ke wehe ʻia ka ʻōnaehana palekana palekana i ka manawa a i ʻole, e alakaʻi pū ia i kahi piʻi nui o ka ʻōnaehana pipeline a me ka hopena hydraulic.

2, ka pōʻino o ka hopena hydraulic

(1) ʻO ka piʻi koʻikoʻi wikiwiki e hōʻino i nā ʻāpana hydraulic, ʻoi aku ka nui o nā sila hydraulic.

(2) Hoʻopuka ka ʻōnaehana i ka haʻalulu ikaika a me ka walaʻau, a hoʻonui i ka mahana o ka aila.
