Makiyi Zvishandiso uye Unyanzvi Kukosha kweCast-Iron Bars muMhepo Compressor Indasitiri
——Kutarisa paWear Resistance, Kugadzikana, uye Mutengo-Kushanda
I. Background uye Core Zvinodiwa zve Air Compressor Industry
Se "simba remoyo" rechikamu cheindasitiri, ma compressor emhepo anoshandiswa zvakanyanya mukugadzira, makemikari engineering, simba, uye mamwe maindasitiri. Zvikamu zvavo zvakakosha zvinofanirwa kuzadzisa zvinotevera zvakaomesesa zvinodiwa:
● High Wear Resistance: Inokwanisa kumira nekumhanya-mhanya kwepiston uye rotors.
●Superior Vibration Damping: Inoshanda mukudzikisa mashandiro evibrations uye ruzha mazinga.
●Yakagadzikana Compressive Strength: Kukwanisa kutsungirira gasi kumanikidzwa kwenguva yakareba.
●Economic Feasibility uye Process Adaptability: Inodhura-inoshanda uye yakakodzera kugadzira zvimiro zvakaoma.
Mabhawa eCast-iron, ane akasarudzika emhando yezvinhu, anobuda semhinduro yakanaka yekuzadzisa izvi zvinodiwa.
II. Core Mashandisiro eMamiriro eCast-Iron Bars muMhepo Compressors
1. Crew Rotor
Application: Pakati pekuti screw air compressors, iyo meshes nemumwe kuti compress mweya.
Cast-Iron Edge: Grey cast iron's self-lubricating graphite inoderedza kupokana, kucheka kushandiswa kwesimba. Kukandira kwayo kuchinjika kunogonesa kurongeka machining eakaomesesa helical profiles yekusina meshing.
2.Matatu-lobe Midzi Pombi Vacuum Rotor
Application: Inotyaira kugadzirwa kwevacuum mumapombi eRoots. Inochengetedza inoenderera gasi kuyerera kuchengetedza system vacuum.
Cast-Iron Edge: Ductile cast iron's high simba uye kuomarara kuramba kukanganiswa mitoro. Kusarudzika kupfeka kuramba kunowedzera hupenyu hwe rotor, kuve nechokwadi chekushanda kwevacuum.
3.Vacuum Pombi Rotor
Application: Kiyi inotenderera chikamu mumapombi akasiyana-siyana ekutsvaira senge vane uye Slide Valve mhando. Inoshandura pombi yekamuri vhoriyamu kuti ibudise gasi uye kugadzira vacuum.
Cast-Iron Edge: Alloyed cast iron, inobatirwa kuomarara kwakawedzera, inomira magasi anokuvadza, kuve nechokwadi chekushanda kwenguva refu.
4.Housing
Application: Inovhara zvinhu zvose zvemukati zvemhepo compressors.Inopa rubatsiro rwemaitiro, inomira mukati memukati, uye inodzivirira zvikamu.
Cast-Iron Edge: Gray cast iron's yepamusoro yekukanda kugona inoumba maumbirwo akaomarara. Nesimba rakanyanya rekumanikidza, inobata 7 - 10 bar kudzvanywa uku ichiramba corrosion uye inonyorovesa ruzha.
5.Multi-stage Quantum Pump Yakasanganiswa Shell
Application: Inobatanidza kudzvinyirira kwe-multi-stage mu-high-pressure, high-efficiency compressors.Inobatanidza matanho ekugadzirisa, inotsungirira pamusoro pe600 MPa kudzvinyirira, uye inodzivirira kubuda kwegesi.
Cast-Iron Edge: Nickel- uye chromium-alloyed ductile cast iron inopa yakakwirira-tembiricha uye kudzvinyirira kuramba, kuve nechokwadi chakagadzikana multi-stage kushanda.
6.Multistage Quantum Vacuum Rotor
Application: Inoshanda pamwe nehoko yakasanganiswa mu-high-vacuum systems.Inowana mazinga akakwirira ekutsvaira kuburikidza ne-multi-stage gas extraction.
Cast-Iron Edge: Ductile cast iron inopa simba rekutanga, kusangana nezvinodiwa zvekupfeka kuramba uye kugadzikana kwedimensional munzvimbo dzakakwirira-vacuum.
7.Inane rotor
Application:Iyo vane rotor yepombi yevacuum inogadzira iyo inodiwa vacuum nekushandura cyclic vhoriyamu yemakamuri akavharwa akaumbwa nemavanes uye nemuviri wepombi panguva yekumhanyisa-kutenderera, ichigonesa kusveta gasi, kudzvanya, uye kupera simba.
Cast-Iron Edge: Yakanyanya Wear Resistance: Inodarika simbi ine 30% yenguva refu yehupenyu, inoderedza kugadzirisa. Self-Lubricating Design: Graphite zvimiro zvinovimbisa kushanda kwakanyarara uye yakakwirira vacuum kunyatsoita.
Ⅲ. Cast Iron vs. Aluminium & Simbi: Sei Ichikunda muMhepo Compressors
Aluminium Alloys: Chiedza asi Chishoma
Nepo aluminium ichipenya mune isingaremi compressor ine yekupisa kwayo conductivity, inotarisana nematambudziko munzvimbo dzakaoma-kunetsekana. Pasi pekudzvinyirirwa kwakasimba uye kupokana mumarotor nemasilinda, kuderera kwesimba realuminium uye kupfeka kuramba kunogona kutungamira mukupfeka nguva isati yakwana uye nyaya dzekuita. Kanda simbi inopindira seimwe yakasimba-inopa kusimba kusingaenzaniswi kune inorema-basa maoparesheni pasina kukanganisa kuvimbika.
Simbi: Yakasimba asi Inodhura
Simba rine mukurumbira reSimbi rinouya nemutengo. Mutengo wayo wepamusoro wezvinhu uye kugadzira kwakaoma kunowedzera kukakavara mukugadzira. Cast iron inopa yakangwara chiyero: inoda kufanana nesimbi yemusimboti kuita kune akawanda compressor zvikamu uku ichicheka mitengo ne30-50%. Kukandwa kwayo kwepamusoro kunogonesa kuomesesa, pedyo-net-shape zvikamu-kukurumidza kugadzirwa uye kupa vanogadzira mukana wemakwikwi.
VI. Ongororo yeZvakakosha zveCast-Iron Materials
●Pfeka Resistance: Inoderedza mareti ekupfeka emasilinda uye piston mhete, kuderedza gadziriso frequency.
●Vibration Damping uye Noise Reduction: Graphite chimiro chinotora vibrational simba, inovandudza kunyarara kwemidziyo.
●Compressive Strength: Inomira gasi rinopfuura 10MPa, kuve nechokwadi chekushanda kwakachengeteka.
●Casting Processability: Inofambisa kuumbwa kwezvakaoma zvemukati zvimiro (zvakadai semvura - inotonhorera mhepo nzira).
●Mutengo - Kushanda: Kuenzaniswa nesimbi yakaumbwa, mutengo wakakwana webasa unoderedzwa ne
●30% -45%
Mabhawa eCast-iron, ane chiyero chisingadzoreki pakati pekuita uye mutengo, anoenderera mberi achifambisa kufambira mberi kwetekinoroji muindasitiri yemhepo compressor. Nekubudirira mune zvekugadzirisa matekinoroji uye nemazvo ekugadzirisa matekinoroji (sezvinoratidzwa nemaitiro matsva emabhizinesi akaita seHenggong Precision), zvinhu zvakakandwa-simbi zvinozoita basa rakatonyanya kukosha mukusimudzira macompressor emhepo akananga kushanda kwepamusoro, ruzha rwakaderera, uye hupenyu hurefu hwesevhisi.
