1. Chii chinonzi accumulator
Hydraulic accumulator chishandiso chekuchengeta simba.Mune accumulator, simba rakachengetwa rinochengetwa muchimiro chegasi rakamanikidzwa, rakatsikirirwa chitubu, kana mutoro wakasimudzwa, uye rinoshandisa simba kumvura isingadhurike.
Accumulators anobatsira zvakanyanya mumagetsi emagetsi masisitimu.Izvo zvinoshandiswa kuchengetedza simba uye kubvisa pulses.Inogona kushandiswa mu hydraulic systems kuderedza saizi yepombi yemvura nekuwedzera pombi yepombi.Izvi zvinoitwa nekuchengetedza simba mupombi panguva yakaderera kudiwa chikamu.Ivo vanogona kuita seanonoke uye anonyudza ekuchinja uye pulses.Vanogona kuvharidzira kurova uye kuderedza kuzununguka kunokonzerwa nekukasira kutanga kana kumira kwesimba silinda mu hydraulic circuit.Kana iyo mvura ikakanganiswa nekukwira kwekushisa nekudonha, iyo accumulator inogona kushandiswa kudzikamisa shanduko yekuchinja muhydraulic system.Vanogona kuburitsa mvura pasi pekumanikidzwa, segirisi nemafuta.

Parizvino, anonyanya kushandiswa accumulators ari pneumatic-hydraulic marudzi.Basa regesi rakafanana nebuffer spring, rinoshanda nemvura;iyo gasi inoparadzaniswa nepiston, yakaonda diaphragm kana air bag.

2. Kushanda musimboti we accumulator

Pasi pechiito chekumanikidza, vhoriyamu shanduko yemvura (pasi peiyo tembiricha yenguva dzose) idiki kwazvo, saka kana pasina sosi yemagetsi (kureva, kuwedzera kweiyo-yakanyanya-kumanikidza mvura), kudzvanywa kwemvura kunodonha nekukurumidza. .

Iyo elasticity yegesi yakakura kwazvo, nekuti gasi rinodzvanywa, kana iri vhoriyamu shanduko yakakura, iyo gasi inogona kuramba ichichengetedza yakanyanya kudzvinyirira.Naizvozvo, kana iyo accumulator iri kuwedzera hydraulic mafuta eiyo hydraulic system, iyo yakanyanya-kudzvanywa gasi inogona kuramba ichichengetedza kudzvanywa kweiyo hydraulic mafuta kana huwandu hwemvura hwachinja.Inova diki, zvichiita kuti hydraulic oiri irasikirwe nekumanikidza nekukurumidza.

Kana iri nitrogen, chikonzero chikuru ndechekuti nitrogen yakagadzikana muzvisikwa uye haina oxidation kana kuderedza zvinhu.Izvi zvakanaka kwazvo kuchengetedza kushanda kwe hydraulic mafuta uye hazvizokonzerese oxidation / kuderedza denaturation ye hydraulic mafuta!

Nitrogen ndiyo pre-charge pressure, inoiswa mu airbag ye accumulator uye inoparadzaniswa ne hydraulic oil!Paunozadza accumulator ne hydraulic oil, nekuda kwekumanikidzwa kwe nitrogen air bag pamafuta e hydraulic, kureva kuti, kudzvinyirira kwe hydraulic mafuta kwakaenzana ne nitrogen pressure.Sezvo mafuta e hydraulic anopinda mukati, iyo nitrogen air bag inomanikidzwa, uye iyo nitrogen pressure inowedzera.Iko kudzvanywa kwemafuta kunowedzera kudzamara iyo hydraulic oiri yasvika pakudzvanywa!

Basa re accumulator nderekupa imwe kudzvanywa kwe hydraulic oiri, iyo inogadzirwa nesimba re nitrogen!

3. Basa guru re accumulator

1. Yekubatsira magetsi
Iwo ma actuators emamwe hydraulic masisitimu anoita nguva nenguva uye iyo yakazara nguva yekushanda ipfupi kwazvo.Kunyangwe ma actuators emamwe hydraulic masisitimu asingaiti nguva nenguva, kumhanya kwavo kunosiyana zvakanyanya mukati mekutenderera kwekushanda (kana mukati mekurohwa).Mushure mekunge accumulator yaiswa muhurongwa uhu, pombi ine simba rakaderera inogona kushandiswa kuderedza simba remotokari huru, kuitira kuti iyo yose hydraulic system idiki muhukuru, chiedza muhuremu, uye isingadhuri.

2. Senzvimbo yekukurumidzira magetsi
Kune mamwe masisitimu, kana pombi ikatadza kana simba rakundikana (mafuta anopihwa kune actuator anongoerekana avhiringidzwa), iyo actuator inofanira kuramba ichizadzisa zviito zvinodiwa.Semuenzaniso, kuitira kuchengeteka, piston tsvimbo ye hydraulic cylinder inofanira kudzoserwa muhumburumbira.Muchiitiko ichi, accumulator ine simba rakakodzera inodiwa sesimba rekukurumidzira.

3. Zadzazve kuvuza uye chengetedza nguva dzose kumanikidza
Kune masisitimu ayo iyo actuator isingashande kwenguva yakareba, asi kuti irambe ichimanikidza, accumulator inogona kushandiswa kutsiva kuvuza, kuitira kuti kudzvanywa kurambe kuchiitika.

4. Bvisa hydraulic shock
Nekuda kwekukasira kushanduka kwekutungamira kwevharuvhu inodzosera, kumira kamwe kamwe kwepombi yehydraulic, kumira kamwe kamwe kwekufamba kweiyo actuator, kana kunyangwe kudiwa kwechimbichimbi braking kweiyo actuator, nezvimwewo, iyo mvura inoyerera mukati iyo pombi ichachinja zvakanyanya, zvichikonzera kuvhunduka (mafuta hit).Kunyange zvazvo kune chivharo chekuchengetedza muhurongwa, ichiri chisingadzivisiki kubudisa kuputika kwenguva pfupi uye kuvhunduka kwekumanikidzwa.Uku kudzvinyirirwa kwekuvhunduka kunowanzo kukonzeresa kutadza kana kukuvadzwa kwezviridzwa, zvikamu, uye zvisimbiso muhurongwa, kana kuputika kwepombi, uye zvakare inoita kuti sisitimu iburitse zviri pachena mavibrations.Kana accumulator yakaiswa pamberi pekuvhunduka kwevhavhavha yekudzora kana hydraulic cylinder, kuvhunduka kunogona kubatwa uye kuderedzwa.

5. Bvisa pulsation uye kuderedza ruzha
Kuyerera kwepombi kunokonzeresa kudzvanywa, zvichikonzera kusaenzana kwekufamba kweiyo actuator, zvichikonzera kudedera uye ruzha.Batanidza inonzwika uye diki inertia accumulator inopindirana pakubuda kwepombi kuti itore kuyerera uye kudzvanywa kwemhepo uye kuderedza ruzha.
