Sechikamu chikuru che hydraulic cylinder, iyo piston tsvimbo inoshandiswa munzvimbo yakaoma yakatenderedza uye inoora;Nekuda kweizvozvo, yemhando yepamusoro yekudzivirira layer yakakosha.Parizvino, electroplating yakaoma chrome inzira yakapararira.Nekuda kwekuita kwayo kwakasimba uye mutengo wakaderera, electroplated hard chrome inzira yakajairika yekurapwa kwepiston tsvimbo.
Chimiro chepiston rod coating
1) Kuoma
Kuomarara chinhu chakakosha chepiston rodhi coatings.Mabhandi anoratidza kuoma kwakashata kana kusasimba zvakakwana haakwanise kutora simba rakawanda panguva yedombo rekona kana giriti yakaoma inorova piston tsvimbo, kukuvara kwepamusoro kunobva kwaitika nyore, uye hydraulic cylinder inozotadza kushanda nekukasira nekuda kwekuputira delamination kana kupisa.
Muedzo wekukanganisa bvunzo ine simba umo muenzaniso wakasarudzwa unowanzo kurohwa nekutyoka neswing pendulum.Miedzo yakajairika yerudzi urwu ndeye Charpy V-notch bvunzo uye iyo Izod bvunzo iyo inotsanangurwa muASTM E23.Musiyano wemusimboti pakati pezviyedzo zviviri ndiyo nzira iri mumuenzaniso inogadziriswa.
2) Corrosion resistance
Nekuda kwehurombo hwekushanda nharaunda, corrosion kuramba kwakakosha kune hydraulic cylinder piston rod coating.Iyo Munyu yekupfapfaidza bvunzo ndeye yakajairwa yakajairwa bvunzo nzira inoshandiswa kutarisa kuomarara kwe hydraulic cylinder piston rod coating;iyo inomhanyisa corrosion resistance bvunzo uye kutaridzika kwezvigadzirwa zvekuora kunoongororwa mushure menguva yenguva.
Midziyo yekuyedza sezvakaratidzwa mumufananidzo 4 ine kamuri yekuyedza yakavharwa, uko mhinduro ine munyu, kunyanya mhinduro yesodium chloride, inopfapfaidzwa nemuromo.Izvi zvinogadzira nharaunda inoora mukamuri uye nekudaro, zvikamu mairi zvinorwiswa pasi peiyi mhepo yakakomba yekuora.Miedzo yakaitwa nemhinduro yeNaCl inozivikanwa seNSS (neutral salt spray).Mibairo inowanzoongororwa semaawa ekuyedza muNSS pasina kutaridzika kwezvigadzirwa zvecorrosion.Mimwe mhinduro iASS (acetic acid test) uye CASS (acetic acid ine copper chloride test).Kuvakwa kweChamber, maitiro ekuyedza, uye maparamendi ekuyedza zvakamisikidzwa pasi pezviyero zvepasirese nenyika, zvakaita seASTM B117, DIN 50021, uye ISO 9227. Mushure menguva yekuedzwa, sampu inogona kuyerwa zvichienderana nenzvimbo ine ngura uchishandisa referensi standard sezvakaratidzwa. mutafura 1.
3) Pfeka kuramba
Sechikamu chekufambisa magetsi, tsvimbo yepiston inoda kufamba ichienda uye ichidzoka kazhinji, panguva imwe chete kupfeka kunoitika panguva yekutsvedza pamusoro pekuisa chisimbiso pacylinder.Saka kupfeka kuramba chinhu chakakosha chinodiwa kwehupenyu hwepiston.Kuoma kwepamusoro ndiyo parameter yakakosha yekuramba kupfeka.Kunze kwekuomarara, corrosion kuramba uye kupfeka kuramba, zvinoenderana neakasiyana indasitiri zviyero uye zvinodiwa nevatengi, imwe nhanho yepiston tsvimbo yekupfeka yakanyorwa mutafura2.
