Shot blasting ahoɔden nkɛntɛnso ne dwumadie
1. Nsunsuanso a ɛwɔ shot blasting ahoɔden mu
Shot blasting strengthening yɛ adwuma a ɛyɛ nwini a ɛhyɛ dade den. Ɛde afiri a wɔde bɔ tuo di dwuma de hwɛ sɛnea atopae a ɛde ahoɔhare kɛse -tu wɔ adwuma no ani so, na ɛma plastic deformation ba soro layer no. Eyi ma adwuma no microstructure ne stress tebea tu mpɔn, na ɛnam so ma ne dwumadi yɛ kɛse. Nneɛma atitiriw a efi mu ba no bi ne:
A. Ɔbrɛ nkwa nna a ɛbɛma atu mpɔn ne mpaapaemu a wofi ase a wosiw ano
Eyi ne mfaso titiriw a ɛwɔ shot blasting ahoɔden so: Ɛdenam residual compressive stress layer a ɛyɛ pɛ na wotumi di so wɔ adwumayɛbea no ani denam shot blasting so no, ɛko tia tensile stress a ɛsesa a adwuma no de ba no, na ɛnam so siw ɔbrɛ mpaapaemu a ɛba ne ntrɛwmu ano. Wɔ nneɛma a adwennwen-a ɛyɛ den te sɛ gear ne spring ho no, wobetumi ama ɔbrɛ nkwa nna akɔ soro mpɛn pii anaa mpɛn du du mpo, na ɛtew asiane a ɛwɔ hɔ sɛ sẽ bebubu na abubu no so kɛse.
B. Optimizing surface micro-adwuma na enhancing wear resistance ne hardness
Nkɛntɛnso a atuo no nya no ma dade nnua a ɛwɔ soro a ɛwɔ soro no yɛ fɛ na ɔdan no yɛ den, na ɛma ɔfasu no yɛ den na ɛko tia sɛ ɛbɛsɛe no tu mpɔn tẽẽ; bere koro no ara mu no, ebetumi ama adwinnade agyiraehyɛde ne burrs a wɔde mfiri a wɔde yɛ adwuma gyaw no ayɛ mmerɛw, ayi ɔfasu so micro- sintɔ ahorow afi hɔ, na atew adwennwen a ɛwɔ mu no so.
C. Synergistically enhancing anti-corrosion ne coating adhesion
Ɔkwan biako so no, nhyɛso a aka no betumi asiw ɔkwan a nneɛma a ɛyɛ mmerɛw no fa so no kwan, na ama adwuma no tumi a ɛko tia nhyɛso a ɛyɛ nsɛe no atu mpɔn; ɔkwan foforo so no, shot blasting ayaresa betumi anya Sa2.5 level a ɛho tew wɔ soro, asi atetesɛm acid ahohoro akwan ananmu na wɔakwati hydrogen embrittlement asiane ahorow, hwɛ hu sɛ nea wɔde kata so akyiri yi no bɛbata ISO 1 gyinapɛn ho, na atrɛw nkwa nna a anti-corrosion coatings no mu kɛse.
D. Nkyekyɛmu a ɛgyina pintinn a wɔbɛma atu mpɔn na wɔatew deformation asiane so
Shoo blasting nkɛntɛnso no betumi apete nhyɛso a aka no pɛpɛɛpɛ wɔ adwuma no mu, ama adwennwen kyekyɛ tebea no ayɛ papa, atew nea ebetumi aba sɛ deformation ne mpaapaemu bere a edi hɔ a wɔyɛ ne ɔsom adwuma no so, na ama fit pɛpɛɛpɛ ne dimensional stability a ɛwɔ precision components no atu mpɔn.
2. Titiriw application akwankyerɛ a shot blasting ahoɔden:
Wɔde shot blasting ahoɔden adi dwuma kɛse wɔ high-end manufacturing fields a ahotoso a ɛkorɔn yiye ne nkwa nna ho ahwehwɛde. Nsɛm a ɛtaa ba no bi ne:
A. Kar a wɔyɛ (ɛyɛ 34% wɔ gua so ahwehwɛde mu, ɛyɛ adwuma kɛse a wɔde di dwuma) .
Core treatment of key components subjected to alternating loads: suspension springs, valve springs, transmission gears, engine crankshafts, connecting rods, chassis brackets, ne nea ɛkeka ho, a ɛdi nnwuma mu ɛyaw nsɛntitiriw te sɛ spring fatigue fracture, gear tooth breakage/pitting, ne crankshaft fatigue failure ho dwuma, na ɛyɛ adeyɛ a ɛho hia ma core components a ɛwɔ kar nneɛma mu.
B. Ahunmu Ahunmu
Nneɛma titiriw a wɔde di dwuma wɔ tebea horow a emu yɛ den mu: wimhyɛn a wɔde si fam, turbine blades, fuselage structural components, engine discs ne shafts, ne nea ɛkeka ho, wɔ mmeae a ɛkorɔn{1}}ɔsoro ne nea ɛba fam-ɔhyew, adesoa kɛse-adesoa, a ɛma afã horow no ɔbrɛ ne nhyɛso a ɛko tia nsɛe no yɛ kɛse, na ɛma wimhyɛn no yɛ ahobammɔ.
C. Adansi mfiri ne nnwinnade a emu yɛ duru
Nneɛma a ɛko tia adesoa a emu yɛ duru-aduru: excavator bokiti abaa, crawler mprɛte, loader sẽ, krane structural afã horow, ne nea ɛkeka ho, a ɛnyɛ sɛ eyi oxide nsenia a ɛwɔ soro nko na mmom ɛma soro denden ne nea ɛko tia nso yɛ kɛse, a wɔde thermal spraying composite mfiridwuma aka ho no betumi atrɛw bokiti sẽ nkwa nna mu mpɛn 8.
D. Mframa mu ahoɔden ne ahoɔden adwumayɛbea
Mframa gear box gears, mframa abantenten, bearings, nuklea ahoɔden nhyehyɛe afã horow, ne nea ɛkeka ho a wɔde di ɔbrɛ ho haw ahorow a ɛwɔ mframa ahoɔden afã horow mu wɔ adesoa a ɛsesa bere tenten ase, bere a ɛma coating adhesion ne anti-corrosion nkwa nna a ɛwɔ abantenten adan ne dade adan akɛse-scale afoforo mu no yɛ kɛse, a ɛyɛ nsakrae ma ɛne ahwehwɛde ahorow a ɛwɔ bere tenten-bere abɔnten so som.
E. Keteke so akwantu
Keteke nhama a wɔde kyekyere nneɛma, aksel, gearbox afã horow, kar nipadua nhyehyɛe afã horow, ne nea ɛkeka ho a wɔbɛsa, ahwɛ ahu sɛ wotumi de ho to keteke akwantu afã horow so wɔ tebea a ɛwosow kɛse-frequency ne adesoa a emu yɛ duru-adesoa tebea mu, na ɛtew nsiesie ho ka so.
F. Aduruyɛ ne nneɛma titiriw
Wɔ titanium aduru a wɔde ayɛ nkwaa ne nea wɔde hyɛ nipadua mu ho no, shot blasting ayaresa yɛ nanocrystalline layer wɔ soro, na ɛma biocompatibility tu mpɔn kɛse; bere koro no ara mu no, ɛma nnuruyɛ mu dade afã horow no ntumi nsɛe na ɛnsɛe, na ɛsakra ma ɛne tebea a wɔde ahyɛ onipa nipadua mu no hyia.
G. Dade nhyehyɛe akɛse-scale anti-corrosion pre-treatment
Shot blasting ayaresa ansa na wɔde akata dade adan akɛse te sɛ bridges, po so ahyɛn, tank, ne pipelines so, de asi atetesɛm mu acid ahohoro rust a woyi fi hɔ ananmu, a ɛnyɛ sɛ ɛma coating adhesion tu mpɔn nko na mmom ɛkwati hydrogen embrittlement sɛe nso, a ɛyɛ standard pre-treatment process ma heavy anti-corrosion projects.
