A matsayin babban ɓangaren tsarin sarrafa ruwa, aikin bawul ɗin solenoid na hydraulic yana tasiri kai tsaye ga aminci da ingancin kayan aiki. Tsarin gyare-gyare shine mabuɗin mahimmanci don ƙayyade ingancin bawul ɗin solenoid, wanda ya haɗa da cikakken aikace-aikacen zaɓin kayan, ƙirar tsari, da fasahar masana'anta. Wannan labarin zai yi bayani dalla-dalla kan mahimman mahimman abubuwan aikin gyare-gyaren bawul ɗin hydraulic solenoid daga mahangar ƙirar ƙira, gyare-gyaren kayan aiki, da aiwatarwa-.
I. Mold Design da Manufacturing
Na'ura mai aiki da karfin ruwa solenoid yawanci ana ƙera su ta amfani da daidaitaccen gyare-gyaren allura ko mutu - simintin gyare-gyare. Daidaiton ƙirar ƙirar yana tasiri kai tsaye ga daidaiton girman jikin bawul ɗin. Ƙirar ƙira tana mai da hankali kan ma'aunin tashoshi da tsarin tsarin sanyaya: babban diamita dole ne ya dace da ƙarfin narkewar filastik, kuma tashoshin reshe yakamata su kasance da madaidaicin giciye{3}} don rage girman asarar matsa lamba. Ya kamata a rarraba tashoshi na ruwa mai sanyaya a ko'ina a kusa da rami na mold, yana tabbatar da bambance-bambancen zafin jiki tsakanin digiri ± 2 don hana mannewar bawul core saboda rashin daidaituwa. Don jikin bawul ɗin ƙarfe da ke aiki ƙarƙashin matsi mai ƙarfi, mutu{8}}ya kamata a yi gyare-gyaren simintin da H13 mai zafi{10}}ƙarfe mai aiki da nitrided don ƙara taurin saman (Mafi girma ko daidai da HV900) don jure wa maimaita nauyin tasiri.
II. Tsarin Gyaran Abu
1. Plastic Valve Jikin Molding
Ana zabar robobin injiniya kamar PA{0}}GF30 (mai ƙunshe da 30% fiber gilashin) don juriyar mai da ƙarfinsu. Siffofin gyare-gyaren allura suna buƙatar kulawa mai ƙarfi: saita zafin jiki na ganga a digiri 260-280, matsa lamba na allura 80-120 MPa, da riƙe lokacin daidaitawa gwargwadon kauri na bango (yawanci 1-3 seconds / mm). Don kawar da damuwa na ciki, ana buƙatar annealing a digiri 80 bayan rushewa, sannan kuma riƙe 2-hour don daidaita girman.
2. Metal Valve Jikin Molding
Don manyan aikace-aikacen matsa lamba, aluminium alloy (kamar ADC12) ko mutuwar tagulla - ana yawan amfani da simintin gyare-gyare. Die-Simintin tsarin simintin su ne: alloy zafin jiki 650-700 digiri, mold zafin digiri 180-220, da haɓaka matsa lamba 50-80 MPa. Mahimman abubuwan rufewa suna jurewa kammalawar CNC na gaba don tabbatar da kwanciyar hankali Kasa da ko daidai da 0.01 mm. Ana amfani da impregnation Vacuum don cike lahani na microporous, yana ƙara ƙimar matsa lamba zuwa sama da 35 MPa.
III. Tsarin Haɗin Haɗin Wutar Lantarki
An raunata wutar lantarki ta hanyar amfani da injin iska ta atomatik. Wayar da aka yi wa lakabi da diamita na 0.3-0.5mm tana da rauni sosai a cikin yadudduka da yawa, tare da rufin fim na polyimide tsakanin yadudduka. Babban abu shine ƙarfe mai tsafta na lantarki na DT4, an haɗa shi don rage ƙarfin ƙarfi (Ƙasa da ko daidai da 80A/m), kuma an haɗa shi da tushen bawul ta hanyar brazing na tushen azurfa don tabbatar da lokacin amsawa na ƙasa da 10ms. Nada da jikin bawul an lullube su da resin epoxy, tare da juriya mai girma fiye da 100MΩ bayan warkewa.
IV. Buga -Tsarin sarrafawa da Kula da inganci
Bawul ɗin solenoid da aka ƙera yana ɗaukar injin auna ma'auni mai girma uku{0} don duba maɓalli mai mahimmanci (kamar juriyar juzu'in kujerun bawul na ±0.005mm) kuma ya wuce gwajin iska (daidaicin gwajin gwajin helium na 1 × 10⁻⁹ Pa·m³/s). Don jikin bawul ɗin robobi, ana kuma yin gwajin zagayawa mai girma{5} daga -40 zuwa digiri 120 don tabbatar da juriyar abin.
Kammalawa
Tsarin gyare-gyare don bawul ɗin solenoid na na'ura mai ba da hanya tsakanin hanyoyin sadarwa yana wakiltar tsaka-tsakin kimiyyar kayan aiki, ƙirar ƙira, da kuzarin ruwa. Ta hanyar haɓaka ƙirar ƙira, sarrafa daidaitattun sigogin gyare-gyare, da haɓaka hanyoyin sarrafawa, daidaiton samfur da dorewa na iya ingantawa sosai. A nan gaba, tare da ci gaban masana'antun ƙari da fasahar kayan haɗaka, gyare-gyaren bawul ɗin solenoid zai ƙara haɓaka zuwa ƙima mai sauƙi da masana'anta.
