A na-ejikọta excibration vibration na ụfọdụ igwe na akụrụngwa iji mepụta ike mmụọ, bụ akụkụ dị mkpa nke iji ọrụ ọrụ igwe. Ihe na-eme mkpọtụ nwere ike ime ka ihe ahụ nweta otu ụdị na ogo nke ịma jijiji, ka o wee nwee ike iji mezuo ịma jijiji na nyocha ike na ihe ahụ, ma ọ bụ dozie ngwa ọrụ nyocha na ihe mmetụta. A pụkwara iji ihe na-eme mkpọtụ dị ka ihe na-akpali akpali iji mepụta igwe vibration, nke nwere ike ịmata njem, nyocha, nchịkọta, ịkpụzi na tamping nke ájá ájá na gravel. Dị ka ụdị ntụrụndụ dị iche iche si dị, a ga-ekewa ihe na-akpali akpali na ụdị eletriki inertia, ụdị electromagnetic, ụdị electro-hydraulic, ụdị pneumatic na ụdị hydraulic. Onye na - eme ọiterụ nwere ike ịmepụta enweghị atụ ma ọ bụ multidirectional, harmonic ma ọ bụ ike anharmonic excitation.

Ọdụdọ vibration eletriki

A na-eri nri nke oge a n'ime eriri na-agagharị iji mee ka eriri ahụ na-ama jijiji n'okpuru ọrụ nke ike eletriki magnet na mpaghara magnet. Ogiri magnetik nke eletrik eletrik eletrik (Fig. 2 [eserese eserese nke eletriki eletriki eletriki]) na-eme site na ugbu a na-agafe na mkpịsị obi ọkụ, wee na-agbanwe ugbu a.

 

Nhazi usoro ihe omuma

Mgbe etinyere ọkụ eletrik na eriri igwe na-agagharị, ihe na-emegharị ahụ na-emetụta oge a na-emegharị electromagnetic, nke na-eme ka mkpịsị ọbara eje iji mee ka ọ na-emegharị. Enwere ike inweta vibration a na-atụ anya site na ịkpọtụrụ mkpanaka ejector na akụkụ nwere obi ụtọ.

 

Mmetụta electromagnetic

Mgbe oge nke oge a na-abanye n'ime eriri electromagnet, a na-eme ike ọgbụgba oge n'etiti akụkụ obi ụtọ na electromagnet. A na-ejikarị electromagnetic vibration exciter eji arụ ọrụ vibration (Fig 3 [schematic diagram of electromagnetic vibration exciter]) nke a na-ejikọkarị ya na isi electromagnet na armature nwere eriri igwe, a na-etinyekwa mmiri n’etiti etiti igwe na armature. Mgbe eriri igwe na-abanye AC, ma ọ bụ AC gbakwunyere DC, ma ọ bụ mgbe emezigharị okirikiri nke usu ahụ.

 

Cirit dị egwu

Mgbe etinyere ihe dị ugbu a, enwere ike ịmegharị ikike ịmegharị oge. Ọtụtụ mgbe, a na-edozi armature ahụ ozugbo na akụkụ ọrụ ya ka ọ maa jijiji.
