Zvinhu Zvokufunga nezvazvo Paunenge Uchisarudza Nozzle Saizi
Zvinhu Zvokufunga nezvazvo Paunenge Uchisarudza Nozzle Saizi
Paunosarudza saizi yemupumburu wejecha, zvinhu zvakati wandei zvinofanirwa kuverengerwa. Izvi zvinhu zvinosanganisira Abrasive Type uye Grit Size, saizi uye mhando yemhepo compressor yako, yaunoda kudzvanywa uye velocity yenozzle, mhando yepasi iri kuputika, uye chaiyo yekushandisa zvinodiwa. Ngationgororei zvakadzama mune chimwe nechimwe chezvinhu izvi.
1. Sandblast Nozzle Size
Paunenge uchikurukura saizi yemupumburu, inowanzo reva saizi yakaboora (Ø), inomiririra nzira yemukati kana dhayamita mukati memuromo. Nzvimbo dzakasiyana dzinoda mazinga akasiyana ehasha panguva yejecha. Nzvimbo dzakatetepa dzinogona kuda diki diki saizi yekudzikisira kukuvara, nepo nzvimbo dzakaomarara dzichida saizi yakakura yepumburu yekuchenesa kunoshanda kana kubviswa kwemajasi. Izvo zvakakosha kuti titarise kuoma uye kusagadzikana kwepasi riri kuputika pakusarudza saizi yepumburu.
2. Abrasive Type uye Grit Size
Akasiyana mabrasives angangoda chaiwo saizi yemupumburu kuti awane kunyatsoita uye kudzivirira kuvhara kana kusaenzana kuputika mapatani. Semutemo wezvigunwe, muromo wemuromo unofanirwa kunge wakapeta katatu saizi yegrit, ichiva nechokwadi chekuyerera kweabrasive uye kunyatsoita kuputika. Aya anotevera hukama huri pakati penozzle bore size uye grit size:
Grit Size | Minimum Nozzle Bore Size |
16 | 1/4" kana kupfuura |
20 | 3/16 ″ kana kupfuura |
30 | 1/8" kana kupfuura |
36 | 3/32 ″ kana kupfuura |
46 | 3/32 ″ kana kupfuura |
54 | 1/16 ″ kana kupfuura |
60 | 1/16 ″ kana kupfuura |
70 | 1/16 ″ kana kupfuura |
80 | 1/16 ″ kana kupfuura |
90 | 1/16 ″ kana kupfuura |
100 | 1/16 ″ kana kupfuura |
120 | 1/16 ″ kana kupfuura |
150 | 1/16 ″ kana kupfuura |
180 | 1/16 ″ kana kupfuura |
220 | 1/16 ″ kana kupfuura |
240 | 1/16 ″ kana kupfuura |
3. Kukura uye Rudzi rweMhepo Compressor
Saizi uye mhando yemhepo compressor yako inoita basa rakakosha pakuona saizi yenozzle. Iyo compressor kugona kuendesa huwandu hwemhepo, yakayerwa mu cubic tsoka paminiti (CFM), inokanganisa kudzvanywa kunogadzirwa pamuromo. Iyo yepamusoro CFM inobvumira yakakura bore nozzle uye yakakwirira abrasive velocity. Izvo zvakakosha kuti uve nechokwadi chekuti compressor yako inogona kupa inodiwa CFM kune yako yakasarudzwa nozzle size.
4. Kudzvinyirira uye Velocity yeNozzle
Kudzvinyirirwa uye kumhanya kwemhuno kunoita basa rakakosha pakuona kushanda kwejecha. Kudzvinyirirwa, kunowanzoyerwa muPSI (Pounds per Square Inch), kunokanganisa zvakananga kumhanya kwezvikamu zvinoputika. Kudzvinyirirwa kwepamusoro kunokonzeresa kuwedzera kwechimedu velocity, ichipa simba guru rekinetic pakukanganisa.
5. Zvakananga Application Zvinodiwa
Imwe neimwe sandblasting application ine yayo yakasarudzika zvinodiwa. Semuyenzaniso, basa rakaomarara rinogona kuda saizi diki yepumburu kuti uwane mibairo chaiyo, nepo nzvimbo dzakakura dzepamusoro dzingada saizi yakakura yekuvhara. Kunzwisisa izvo chaizvo zvinodikanwa zvechishandiso chako kunobatsira iwe kuona yakanyatsokodzera nozzle size.
Nekutarisisa zvinhu izvi uye nekuwana chiyero chakakodzera, unogona kusarudza iyo yakakodzera nozzle saizi yejecha rako rekushandisa, kuve nechokwadi chinoshanda uye chinoshanda mhedzisiro uchiwedzera hupenyu hwemidziyo yako.
Semuyenzaniso, Kuchengeta yakaringana nozzle pressure ye100 psi kana yakakwira kwakakosha kuti uwedzere kuputika kwekuchenesa. Kudonhedza pasi pe100 psi kunogona kukonzera kudzikiswa kweanenge 1-1 / 2% mukubudirira kwekuputika. Zvakakosha kuziva kuti iyi fungidziro uye inogona kusiyana zvichienderana nemhando yeabrasive inoshandiswa, hunhu hwemhuno nepoipi, nemamiriro ekunze akaita semwando uye tembiricha, izvo zvinogona kukanganisa kunaka kwemweya wakadzvanywa. Ita shuwa inopindirana uye yakakwana nozzle kudzvanywa kuti ukwidze mashandiro ako ekuputika.
