Paunenge uchishandisa vharafu, pane kazhinji dzimwe nyaya dzinogumbura, kusanganisira vharafu isiri kuvharwa nzira yese. Ndoita sei? Ivharuvhu yekudzora ine zvakasiyana-siyana zvemukati zvekubuda kwemukati nekuda kwerudzi rwayo rwevharuvhu yakaomesesa chimiro. Nhasi, tichakurukura nzira nomwe dzakasiyana dzemukati wekudzora mavharuvhu ekudonha uye kuongororwa uye kugadzirisa kune yega yega.

1. Varuvhu haisati yavhara kusvika pakuzara kwayo uye actuator zero position setting haina kururama.

Solution:

1) Ivhara nemaoko valve (chokwadi kuti yakavharwa zvachose);

2) Vhurazve vharuvhu nemaoko, chero simba diki risingagone kushandiswa kuishandura;

3) Shandura vharuvhu hafu yekutendeuka mune yakatarisana nzira;

4) Tevere, shandura muganho wepamusoro.

2. Kusundidzira kwechibatiso hakuna kukwana.

Kusundidzira kwechibatiso hakuna kukwana nekuti vharafu ndeyekusundidzira-pasi kunovhara kwakasiyana. Kana pasina kumanikidzwa, zviri nyore kusvika panzvimbo yakavharwa zvakakwana, asi kana paine kumanikidzwa, kukwira kwepamusoro kwemvura hakugone kuverengerwa, zvichiita kuti zvisakwanise kuvhara zvachose.

Mhinduro: tsiva iyo yakakwira-thrust actuator, kana shandura kune yakaenzana spool kuderedza iyo isina kuenzana simba repakati.

3. Kudonha kwemukati kunounzwa nehurombo hwemagetsi ekudzora vharafu yekuvaka mhando

Nemhaka yokuti vagadziri vevharuvhu havadzoreri zvakasimba zvinhu zvevhavha, teknolojia yekugadzirisa, teknolojia yekugadzira, nezvimwewo panguva yekugadzira, nzvimbo yekuisa chisimbiso haisi pasi kusvika kune yakakwirira uye zvikanganiso zvakadai segomba uye trachoma hazvibviswi zvachose, zvichiita kuti mukati mevuza. vharafu yemagetsi.

Mhinduro: Reprosesa iyo yekuisa chisimbiso pamusoro

4. Chikamu chekutonga chevhavha yemagetsi ine simba pakuputika kwemukati kwevhavha.

Mechanical control nzira, kusanganisira mavharuvhu ekugumira ma switch uye pamusoro pe torque switch, ndiyo nzira yechinyakare yekushandisa vharuvhu yemagetsi. Nzvimbo yevharuvhu haina kujeka, chitubu chasakara, uye coefficient yekuwedzera kwekupisa haina kuenzana nekuti zvinhu zvekudzora izvi zvinokanganiswa nekudziya kwakapoteredza, kudzvanywa, uye hunyoro. uye mamwe mamiriro ekunze, ayo ane mhosva yekudonha kwemukati kwevhavha yemagetsi.

Solution: gadzirisa muganhu.

5. Kudonha kwemukati kunounzwa nenyaya nemagetsi ekudzora vharafu kugadzirisa dambudziko

Izvo zvinowanzoitika kuti magetsi ekudzora mavharuvhu atadze kuvhura mushure mekuvharwa nemaoko, izvo zvinokonzerwa nekugadzirisa uye kugadzirisa maitiro. Nzvimbo yekuita yekumusoro uye yakaderera muganho switch inogona kushandiswa kugadzirisa sitiroko yemagetsi control valve. Kana chirwere chacho chikagadziridzwa chiduku, valve yemagetsi haigoni kuvhara zvakasimba kana kuzarura; kana sitiroko ikagadziridzwa yakakura, inokonzeresa yakawandisa torque switch yekudzivirira nzira;

Kana iyo over-torque switch's action value yakawedzera, pachava netsaona inogona kukuvadza vharafu kana nzira yekudzikisa yekufambisa, kana kutopisa mota. Kazhinji, mushure mekunge vheji yemagetsi yemagetsi yakagadziriswa, iyo yakadzika muganhu wekushandura nzvimbo yegonhi remagetsi inogadziriswa nemaoko kuzunungusa valve yemagetsi kusvika pasi, inoteverwa nekuizunungusa munzira yekuvhura, uye muganho wepamusoro unoiswa nemaoko. kuzunungusa vharafu yemagetsi kusvika panzvimbo yakazaruka zvizere.

Saka, vheji yemagetsi haizodzivirirwe kubva pakuvhurika mushure mekuvharwa zvakasimba nemaoko, ichibvumira gonhi remagetsi kuti rivhure uye rivhare zvakasununguka, asi rinozoguma nekubuda mukati megonhi remagetsi. Kunyangwe iyo yemagetsi yekudzora vharafu yakanyatsogadziriswa, sezvo iyo yekumisikidza dhizaini dhizaini inonyanya kugadziriswa, iyo yepakati yainodzora inoramba ichigeza uye ichipfeka vharafu painenge ichishandiswa, izvo zvinozokonzeresa kudonha kwemukati kubva pakuvhara kwevhavha.

Solution: gadzirisa muganhu.

6. Cavitation Kubuda kwemukati kwevhavha yemagetsi kunokonzerwa nekuora kwevhavha inounzwa nemhando isina kururama kusarudzwa.

Cavitation uye kudzvinyirirwa kusiyana kwakabatana. Cavitation ichaitika kana iyo chaiyo yekumanikidza musiyano P yevhavha yakakwirira kupfuura yakakosha kudzvinyirira musiyano Pc ye cavitation. Iyo yakawanda yakawanda yesimba inogadzirwa panguva ye cavitation process apo bubble inoputika, iyo ine simba pane chigaro chevhavha uye nheyo yevhavha. Ivhavha yakawanda inoshanda mu cavitation mamiriro ezvinhu kwemwedzi mitatu kana pasi, zvinoreva kuti valve inotambura neyakaoma cavitation corrosion, zvichiita kuti kudonha kwechigaro chevhavha kusvika ku30% yehuwandu hwekuyerera. Zvikamu zvinoputika zvine chinhu chikuru chinoparadza. Kukuvadza uku hakugone kugadziriswa.

Naizvozvo, iyo chaiyo tekinoroji inodiwa yemagetsi mavharuvhu inosiyana zvichienderana nekwavanoda kushandiswa. Izvo zvakakosha kuti usarudze magetsi ekudzora mavharuvhu zvine hungwaru zvinoenderana nehurongwa hwehurongwa.

Solution: Kuti uvandudze maitiro, sarudza multi-stage nhanho-pasi kana sleeve regulating valve.

7. Kudonha kwemukati kunokonzerwa nekuderera kwepakati uye kukwegura kwevhavha yemagetsi

Mushure mokunge vhavha yemagetsi yemagetsi yakagadziriswa, mushure mekunge imwe nguva yekushanda, vheji yemagetsi yemagetsi ichavharwa nokuti sitiroko yakakura zvikuru semugumisiro wevhavha cavitating, kupera kwepakati, nheyo yevhavha uye chigaro chinopera, uye kukwegura kwezvikamu zvemukati. Kuwedzera kwekudonha kwevharuvhu yekudzora kwemagetsi imhaka yelaxness phenomena. Kudonha kwemukati kwevharuvhu yemagetsi kuchawedzera zvishoma nezvishoma nekufamba kwenguva.

Solution: gadzirisa actuator uye ita nguva dzose kugadzirisa uye calibration.
