1. Chii chinonzi accumulator
Hydraulic accumulator mudziyo wekuchengetedza simba. Mu accumulator, simba rinochengetwa rinochengetwa muchimiro chegasi rakamanikidzwa, chitubu chakamanikidzwa, kana mutoro wakasimudzwa, uye rinoshandisa simba kune mvura isingapindiki zvakanyanya.
MaAccumulators anobatsira zvikuru mumasystem emagetsi emvura. Anoshandiswa kuchengetedza simba uye kubvisa mapulse. Anogona kushandiswa mumasystem ehydraulic kuderedza saizi yepombi yemvura nekuwedzera mvura yepombi. Izvi zvinoitwa nekuchengetedza simba mupombi panguva yekushaikwa kwesimba shoma. Anogona kushanda sekudzikira uye kunyudza kushanduka-chinja uye mapulse. Anogona kudzivirira kuputika uye kuderedza kudedera kunokonzerwa nekutanga kamwe kamwe kana kumira kwesimba remagetsi mu hydraulic circuit. Kana mvura ikakanganiswa nekukwira nekudzika kwekushisa, accumulator inogona kushandiswa kudzikamisa shanduko dzekumanikidza mu hydraulic system. Anogona kubudisa mvura pasi pekumanikidzwa, senge mafuta nemafuta.

Parizvino, ma accumulators anonyanya kushandiswa ndeaya epneumatic-hydraulic. Basa regasi rakafanana nechitubu chebuffer, rinoshanda nemvura; gasi rinoparadzaniswa nepiston, diaphragm yakatetepa kana bhegi remhepo.

2. Nheyo yekushanda kweaccumulator

Pasi pesimba rekumanikidzwa, kuchinja kwehuwandu hwemvura (pasi pekupisa kunogara kuripo) kudiki kwazvo, saka kana pasina simba (ndiko kuti, kuwedzerwa kwemvura ine pressure yakakwira), kumanikidzwa kwemvura kuchaderera nekukurumidza.

Kuoma kwegasi kwakanyanya, nekuti gasi rinogona kudzvanywa, kana vhoriyamu ikachinja zvakanyanya, gasi rinogona kuramba riine kumanikidzwa kwakanyanya. Saka, kana accumulator ichiwedzera mafuta ehydraulic e hydraulic system, gasi rine kumanikidzwa kwakanyanya rinogona kuramba richichengetedza kumanikidzwa kwemafuta e hydraulic kana vhoriyamu yemvura yachinja. Rinova diki, zvichiita kuti mafuta e hydraulic arasikirwe nekumanikidzwa nekukurumidza.

Kana iri nitrogen, chikonzero chikuru ndechekuti nitrogen inogara kwenguva refu uye haina hunhu hwekuoxidation kana kuderedza. Izvi zvakanaka kwazvo pakuchengetedza mashandiro emafuta e hydraulic uye hazvizokonzere kuoxidation/kuderedza denaturation yemafuta e hydraulic!

Nitrogen ndiyo pre-charge pressure, iyo inoiswa mu airbag ye accumulator uye inoparadzaniswa ne hydraulic oil! Paunozadza accumulator ne hydraulic oil, nekuda kwekumanikidzwa kwe nitrogen air bag pa hydraulic oil, ndiko kuti, hydraulic oil inoenzana ne nitrogen pressure. Sezvo hydraulic oil ichipinda, nitrogen air bag inomanikidzwa, uye nitrogen pressure inowedzera. Oil pressure inowedzera kusvika hydraulic oil yasvika pa set pressure!

Basa remuchina wekuunganidza mafuta nderekupa simba remafuta e hydraulic, ayo anogadzirwa nesimba re nitrogen!

3. Basa guru reaccumulator

1. Yekupa simba rekubatsira
Ma actuator emamwe masisitimu e hydraulic anoshanda nguva nenguva uye nguva yese yekushanda ipfupi kwazvo. Kunyangwe ma actuator emamwe masisitimu e hydraulic asingashande nguva nenguva, kumhanya kwawo kunosiyana zvakanyanya mukati menguva yekushanda (kana mukati me stroke). Mushure mekunge accumulator yaiswa musystem iyi, pombi ine simba shoma inogona kushandiswa kuderedza simba re main drive, kuitira kuti system yese ye hydraulic ive diki muhukuru, huremu hushoma, uye isingadhuri.

2. Sesimba remagetsi rekukurumidzira
Kune mamwe masisitimu, kana pombi ikakundikana kana magetsi akakundikana (mafuta anoendeswa kuactuator anongoerekana amiswa), actuator inofanira kuramba ichipedzisa zviito zvinodiwa. Semuenzaniso, kuti pave nekuchengetedzeka, piston rod ye hydraulic cylinder inofanira kudzoserwa mu cylinder. Muchiitiko ichi, accumulator ine simba rakakodzera inodiwa senzvimbo yemagetsi ekukurumidza.

3. Zadzazve mvura inobuda uye ramba uchidzvanya nguva dzose
Kune masisitimu apo actuator isingashande kwenguva yakareba, asi kuti irambe ichimanikidzwa nguva dzose, accumulator inogona kushandiswa kutsiva kubuda kwemvura, kuitira kuti kumanikidzwa kugare kuripo.

4. Bvuma kuvhunduka kwe hydraulic
Nekuda kwekuchinja kamwe kamwe kwenzira yevharuvhu yekudzosera shure, kumira kamwe kamwe kwepombi ye hydraulic, kumira kamwe kamwe kwekufamba kwe actuator, kana kutoda kwekugadzira kwekubhurika kwechimbichimbi kwe actuator, nezvimwewo, kuyerera kwemvura mupaipi kuchachinja zvakanyanya, zvichikonzera kumanikidzwa kwe shock (kurova kwemafuta). Kunyangwe paine vharuvhu yekuchengetedza mu system, zvichiri kudzivirirwa kugadzira kukwira kwenguva pfupi uye kumanikidzwa kwe pressure. Kumanikidzwa uku kwe shock kunowanzo kukonzera kutadza kana kutokuvadzwa kwemidziyo, zvikamu, uye zvidziviriro mu system, kana kuputika kwepaipi, uye zvakare kunoita kuti system ibudise vibrations zviri pachena. Kana accumulator ikaiswa pamberi pe shock source ye control valve kana hydraulic cylinder, kushamisika kunogona kunyudzwa uye kuderedzwa.

5. Nzvera kuputika kwemhepo uye deredza ruzha
Kuyerera kwepombi kunokonzera kutenderera kwesimba, zvichikonzera kumhanya kusina kuenzana kwekufambisa kweactuator, zvichikonzera kudedera neruzha. Batanidza accumulator inonzwisisika uye diki inertia pamwe chete panzvimbo inobuda pombi kuti itore kuyerera kwesimba uye kutenderera kwesimba uye kuderedza ruzha.
