Porogaramu:

Igipimo cy’umuvuduko w’amazi ashongeshwa cya YYP-400E ni igikoresho cyo kumenya imikorere y’amazi ashongeshwa ya polimeri za pulasitiki ku bushyuhe bwinshi hakurikijwe uburyo bwagenwe muri GB3682-2018. Kikoreshwa mu gupima umuvuduko w’amazi ashongeshwa ya polimeri nka polyethylene, polypropylene, polyoxymethylene, ABS resin, polycarbonate, nylon, na fluoroplastics ku bushyuhe bwinshi. Kirakoreshwa mu gukora no gukora ubushakashatsi mu nganda, ibigo n’ibigo by’ubushakashatsi bya siyansi.

Ibipimo by'ingenzi bya tekiniki:

1. Igice cyo gusohora amazi:

Umurambararo w'aho gusohora umuriro: Φ2.095±0.005 mm

Uburebure bw'aho gusohora: milimetero 8.000±0.007

Ubugari bwa silindiri yo gupakira: Φ9.550±0.007 mm

Umurambararo w'umutwe w'inkoni ya piston: 9.474±0.007 mm

Uburebure bw'umutwe w'inkoni ya piston: 6.350±0.100 mm

2. Ingufu zisanzwe zo gupima (Ibyiciro umunani)

Urwego rwa 1: 0.325 kg = (Inkoni ya Piston + Isafuriya yo gupima + Agakoresho gakingira + Uburemere bwa No. 1) = 3.187 N

Urwego rwa 2: 1.200 kg = (0.325 + Umubare 2 0.875 Uburemere) = 11.77 N

Urwego rwa 3: 2.160 kg = (0.325 + Umubare 3 1.835 Uburemere) = 21.18 N

Urwego rwa 4: 3.800 kg = (0.325 + Umubare wa 4 3.475 Uburemere) = 37.26 N

Urwego rwa 5: 5.000 kg = (0.325 + Umubare 5 4.675 Uburemere) = 49.03 N

Urwego rwa 6: 10.000 kg = (0.325 + Umubare 5 4.675 Uburemere + Umubare 6 5.000 Uburemere) = 98.07 N

Urwego rwa 7: 12.000 kg = (0.325 + Umubare 5 4.675 Uburemere + Umubare 6 5.000 + Umubare 7 2.500 Uburemere) = 122.58 N

Urwego rwa 8: 21.600 kg = (0.325 + Umubare 2 0.875 Uburemere + Umubare 3 1.835 + Umubare 4 3.475 + Umubare 5 4.675 + Umubare 6 5.000 + Umubare 7 2.500 + Umubare 8 2.915 Uburemere) = 211.82 N

Ikosa ry'uburemere ni ≤ 0.5%.

3. Ingano y'ubushyuhe: 50°C ~300°C

4. Ubushyuhe buhamye: ± 0.5°C

5. Ingufu zitangwa: 220V ± 10%, 50Hz

6. Ibisabwa ku bijyanye n'aho akazi gakorerwa:

Ubushyuhe bw'ikirere: 10°C kugeza 40°C;

Ubushuhe bungana: 30% kugeza 80%;

Nta kintu cyangiza mu bidukikije;

Nta muyoboro w’umwuka ukomeye;

Idafite Vibration cyangwa Interference ikomeye ya Magnetic Field.

7. Ingano y'igikoresho: 280 mm × 350 mm × 600 mm (Uburebure × Ubugari ×Uburebure)

Imiterere n'Ihame ry'Umurimo:

Igipimo cy’umuvuduko w’amazi ashongeshwa ni ubwoko bw’igipimo cya pulasitiki cyo gusohora. Mu gihe cy’ubushyuhe bwagenwe, icyitegererezo kigomba gupimwa gishyushywa kugeza ku rugero rwo gushongeshwa n’itanura rishyushye cyane. Icyitegererezo cyashongeshwa gihita gisohoka binyuze mu mwobo muto ufite umurambararo runaka munsi y’umutwaro w’uburemere bwagenwe. Mu gukora pulasitiki mu nganda no mu bushakashatsi bw’ibigo by’ubushakashatsi bya siyansi, "umuvuduko w’amazi ashongeshwa" ukunze gukoreshwa mu kwerekana ubusugire, ubukana n’indi miterere y’ibikoresho bya polymer mu gihe cyo gushonga. Icyo bita igipimo cy’umuvuduko w’amazi bivuga uburemere mpuzandengo bwa buri gice cy’icyitegererezo cyashongeshejwe kigahinduka ingano y’amazi mu minota 10.

Igikoresho cy'umuvuduko w'amazi ashongeshwa (uburemere) kigaragazwa na MFR, aho igice ari: garama kuri buri minota 10 (g/min).

Ifishi ni:

MFR(θ, mnom) = tref . m / t

Aho: θ —- ubushyuhe bw'ikizamini

Mnom— - umutwaro w'amazina (Kg)

m —- uburemere mpuzandengo bw'igice cyaciwe, g

tref —- igihe cyo kureberaho (iminota 10), S (amasegonda 600)

t ——- igihe cy'irangiza, s

Urugero:

Itsinda ry'ibipimo bya pulasitiki ryaciwe buri masegonda 30, kandi ibyavuye mu buremere bwa buri gice byari: garama 0.0816, garama 0.0862, garama 0.0815, garama 0.0895, garama 0.0825.

Igiciro mpuzandengo m = (0.0816 + 0.0862 + 0.0815 + 0.0895 + 0.0825) ÷ 5 = 0.0843 (garama)

Hindura muri formula: MFR = 600 × 0.0843 / 30 = 1.686 (garama mu minota 10)
