Kudzidza Mashandisirwo Ekutanga eMavharuvhu Ekubatsira

Ndini Victor. Ndine fekitori ine 6,000 m² muChina uye ndiri mushandi ane mukurumbira vharuvhu yekubatsira nyanzvi.

1. Kudzora Kumanikidzwa uye Basa reKupfuura

Muhurongwa hwemahydraulic hunoshandiswa nepombi inochinjika, huwandu hwekumanikidzwa hunodiwa kuti huenderane nezvinodiwa nemutoro wekushanda. Hunhu hunoda "kudzora kumanikidzwa"—ndiko kuti, kuona kumanikidzwa kwakanyanya kwekushanda kwe Pombi yeHydraulicKune rumwe rutivi, kana actuator isingade kuyerera kwakawanda kudaro, pombi yekudzima yakagadzika ichiri kupa kuyerera kwakasimba. Nzira chete yekubata kuyerera kwakawandisa ndeye kuburikidza nevharuvhu yekurerutsira, iyo inozadza mafuta akawandisa kudzokera kutangi. Pasina izvi, kuyerera kwakawandisa kwaizokonzera kumanikidzwa kwesystem kukwira kusvika padanho rakakwirira zvine njodzi. Nokudaro, muhurongwa hwesimba rehydraulic hwepombi yekudzima yakagadzika, vharuvhu yekurerutsira inoshanda mabasa e "kudzora kumanikidzwa," "kuganhurira kumanikidzwa," uye "kupfuura," sezvakaratidzwa muMufananidzo 3-1(a).

2. Basa reKudzivirira Kuchengetedzeka

Muhurongwa hwe hydraulic umo pombi inochinja-chinja inoshanda senzvimbo yemagetsi, kuyerera kwepombi kunowanzo chinja otomatiki nemutoro, saka kazhinji pane kuyerera kwakawandisa kushoma. Kumanikidzwa kwayo kushanda kunotsanangurwa nemutoro. vharuvhu yekubatsira Inongovhurika chete kuti iwedzere kana kumanikidzwa kwapfuura kukosha kwakatotarwa, zvichidzivirira kukwira kwedzvinyiriro, zvichidzivirira sisitimu kubva pakuzara, uye zvichishanda basa rekuchengetedza, sezvakaratidzwa muMufananidzo 3-1(b).

3. Kuunganidzwa kana Kuburutswa Kwepombi Paunenge Uchidiwa

Mumhando iyi ye hydraulic system, inoshandisa solenoid vharuvhu yekubatsira inoshandiswa, sezvakaratidzwa paMufananidzo 3-1(c). Kana solenoid yasimbiswa, chiteshi chekudzora chekunze che vharuvhu yekubatsira yakabatana netangi, zvichiita kuti pombi ikwanise kuburutsa zvinhu.

4. Kudzora Kumanikidzwa Kure uye Kudzora Kumanikidzwa Kwematanho Maviri

MuMufananidzo 3-1(d), vharuvhu yekudzora kumanikidzwa iri kure yakaiswa panzvimbo iri nyore kushanda. Chiteshi chekudzora chekunze X (chiteshi chekudzora chiri kure) cherudzi rwepilot Vharuvhu Yekubatsira Kwakanyanya yakabatana nevharuvhu yekudzora kumanikidzwa iri kure (vharuvhu yekurerutsira ine kumanikidzwa kwakaderera). Kureva, imba yepamusoro ye Vharuvhu Yekubatsira Kwakanyanya spool yakabatana ne external control port X. Kana solenoid valve yabviswa simba, kana pressure yakagadziriswa yasvika pakugadzirisa remote pressure control valve, main valve spool inosimuka kuti iwedzere simba (pilot valve yayo haichaiti regulatory pressure)—zvichizoita remote pressure control. Kana solenoid valve yawedzerwa simba uye left position yave kushanda, pressure inodzorwa ne Vharuvhu Yekubatsira KwakanyanyaKana vharuvhu ye solenoid yasimbiswa uye nzvimbo chaiyo yashanda, kumanikidzwa kunodzorwa nevharuvhu yekudzora kumanikidzwa iri kure. Izvi zvinopa sisitimu ye hydraulic kumanikidzwa kuviri kunoshanda, kunozivikanwa sekutonga kumanikidzwa kwematanho maviri.

5. Kudzora Kumanikidzwa Kwematanho Akawanda

Sezvakaratidzwa paMufananidzo 4-60, mapombi eA1 neB1 evharuvhu yepilot solenoid inowanzo vharwa akabatana nevharuvhu ine matanho maviri nematanho matatu (vharuvhu inotonga kumanikidzwa) zvichiteerana. Kana vharuvhu huru, mavharuvhu maviri, uye matatu-matanho ekubatsira kumanikidzwa zvakananga akagadziridzwa kune kumanikidzwa kwakasiyana, kudzora kumanikidzwa kwematanho matatu kunogona kuitwa. Semuenzaniso, kana P1 = 20 MPa, P2 = 10 MPa, uye P3 = 5 MPa, ipapo kana masolenoid ese ari maviri abviswa simba, kumanikidzwa kwesystem i20 MPa; kana solenoid 1DT yawedzerwa simba, kumanikidzwa kwesystem i10 MPa; kana solenoid 2DT yawedzerwa simba, kumanikidzwa kwesystem i5 MPa. Kana vharuvhu yepilot solenoid yakavhurika ikashandiswa, system inoburitsa kana solenoid yaderedzwa simba. Kudzora kumanikidzwa kwematanho akawanda kunoda kushandiswa kwevharuvhu yekununura inodzorwa kunze.

Mufananidzo 3-2: Kudzora Kudzvanywa Kwematanho Akawanda (Matanho Matatu) neSolenoid Relief Valve

Sezvakaratidzwa paMufananidzo 3-3, nzvimbo yekutonga mafuta X yevharuvhu huru yekubatsira inofambiswa nepilot 1 yakabatana nevharuvhu ine mativi matatu ine mativi mana yesolenoid 4. Mapotsi A naB evharuvhu yesolenoid akabatana nevharuvhu inotonga kumanikidzwa (vharuvhu yekubatsira zvakananga) 2 na3 zvichiteerana. Kana mavharuvhu matatu ekubatsira 1, 2, na3 akagadziriswa kumanikidzwa kwakasiyana P1, P2, naP3 zvichiteerana, kudzora kumanikidzwa kwematanho matatu kwesystem kunogona kuitwa. Cherechedza kuti P2 naP3 zvinofanirwa kunge zvakaderera pane P1; zvikasadaro, hazvizoshande.

1-3 — Mavharuvhu Ekubatsira; 4 — Vharuvhu YeSolenoid Yenzvimbo Nhatu
