ʻO Liebherr excavator ʻāpana electromagnetic valve coil

ʻO ka loina hana o solenoid valve coil

1. Inductance e pili ana i ka alternating magnetic flux i loko a a puni ka conductor ke hele ka conductor i ka manawa kamaʻilio, a me ka lakio o ka flux magnetic o ka conductor i kēia manawa me kēia flux magnetic.

2. Ke hele ka inductor i ka manawa o DC, inā lōʻihi ka paʻa o nā laina magnetic a puni, ʻaʻole ia e loli me ka manawa; Akā i ka wā e hele ai ka coil electromagnetic i ka manawa kamaʻilio, e hoʻololi nā laina kahua magnetic me ka hala o ka manawa. Wahi a Faradi's electromagnetic induction law-magnetic electricity analysis, ʻo ka hoʻololi ʻana i nā laina kahua magnetic e hoʻoulu i nā mea hiki ma nā ʻaoʻao ʻelua o ka coil, ua like ia me kahi "mea mana hou". Ke puka mai kahi kaapuni i pani ʻia, e hoʻoulu ka mana i hoʻokomo ʻia. Wahi a ke kānāwai o Leng Ci, pono e pale ʻia ka hoʻololi ʻana o nā laina kahua magnetic kumu i ka hiki. Ma muli o ka hoʻololi ʻana o nā laina kahua magnetic kumu mai ka hoʻololi ʻana o ka mana o waho, mai ka hopena pahuhopu, ʻo ka inductance coil ke ʻano o ka pale ʻana i ka hoʻololi ʻana o kēia manawa i ke kaapuni kamaʻilio. He ʻano like ko Inductive coil me ka mechanical inertia, a ua kapa ʻia ʻo "self-induction" i ka uila. ʻO ka mea maʻamau, i ka wā e hoʻohuli ʻia ai ka pahi a i ʻole, e puka mai ana nā ʻulaʻula, ʻo ia ka mea i hoʻokumu ʻia e ka mana ikaika o ka hanana hoʻokomo ponoʻī.

3. Ma kahi huaʻōlelo, i ka wā e loaʻa ai i ka solenoid valve coil ka uila kamaʻilio, e hoʻololi nā laina laina magnetic i ka coil me ka hoʻololi ʻana o kēia manawa, e hopena i ka hoʻomau electromagnetic induction i loko o ka coil. ʻO kēia mea hiki ke hoʻololi ʻia o ka coil i kēia manawa ua kapa ʻia ʻo "self-induced electromotive force".

4. Hiki ke ʻike ʻia e pili wale ana ka inductance i ka helu, ka nui, ke ʻano a me ke ʻano o ka coil, ʻo ia ka inertia o ka inductance coil a ʻaʻohe mea e pili ana i ka wā o waho.
