Matumba ochokera m'matumba a tulo a tulo a tulo, makhothi a valavu. Etc.

Matumba ochokera ku nsalu yathyathyathya - thumba la bokosi, thumba la envelopu, etc.

• Kulemera kwa thumba la PP chonyowa kapena GSM kapena galamala (chilankhulo cham'deralo)

Ngati tikudziwa mtundu wa GSM kapena GPB (Gramu) kapena galamala (yogwiritsidwa ntchito pamsika wina), Titha kutsimikiziridwa mosavuta monga, kuchuluka kwa tepi etc.

•Mtundu Wosokosera

Pali mitundu yambiri yokhotakhota.

Etc.

• Kufuna mphamvu m'thumba

Pofuna kusankha Chinsinsi chosakanikirana, ndikofunikira kudziwa kufunika kwa mphamvu, kofunikira kwambiri ndikusakaniza kovuta, chifukwa mitundu yambiri yowonjezera imawonjezeredwa ku chinsinsi, chomwe chimakhudzana ndi mphamvu ndi engocation%.

•Mtundu waPP TOCKED

Itha kupangidwa ndi mtundu uliwonse malinga ndi zomwe akufuna, monga kusakaniza ndiye Chinsinsi chofunikira kwambiri, malinga ndi zowonjezera, mitundu yosiyanasiyana yazowonjezera zimawonjezeredwa ku chinsinsi ndi mtengo wosiyananso.

Tiyeni titenge chitsanzo chomvetsetsa kuwerengera.

Mwachitsanzo 20 Kuchuluka kwamatumba 50000. (GSM ndi galamala idzafotokozedwanso mwachitsanzo ichi.)

• Choyamba lembani zambiri zomwe zilipo.

• GPB - 100 magalamu

• Kukula - 20 "x 36"

• Kusunthira - kokweza kwambiri ndi pansi sfss

• Mtundu woluka - lathyathyathya

• MEHS 10 x 10

Tsopano tisankhe kutalika kokha.

Popeza, kusunthika kwamphamvu kwambiri ndi pansi ndiko sfss, kuwonjezera 1 "chifukwa cha mikate ndi 1.5" kwa sfss kukula. Kutalika kwa thumba ndi 36 ", kuwonjezera 2.5" Kwa icho, kutalika kodulidwa kumakhala 38.5 ".

Tsopano tiyeni timvetsetse izi ndi njira yoyanjana.

Popeza, timafunikira 38.5 "nsalu yayitali kuti tipange chikwama.

Chifukwa chake, kupanga matumba 50000, 50000 x 38.5 "= 1925000"

Tsopano tiyeni timvetsetsenso za njira yoyanjana yodziwira mu mita.

Kuyambira, 1 mita mu 39.37 "

Kenako, 1 / 39.37 meter mu 1 "

Chifukwa cha "1925000" = 1925000 * 1 / 39.37

= Mamita 48895

Popeza mitundu yambiri ya nkhondo imapangidwanso popanga nsalu, chifukwa chake vati ina% imapangidwa kuposa nsalu yofunikira. Nthawi zambiri 3%.

Motero 48895 + 3% = 50361 metres

= 50400 mita pa Roup

Tsopano, ife tikudziwa kuchuluka kwa nsalu yopanga, kotero tiyenera kuwerengetsa kuchuluka kwa tepi yomwe iyenera kupangidwa.

Popeza kulemera kwa thumba ndi magalamu 100, chinthu chimodzi chodziwira apa ndikuti kulemera kwa ulusiwo kumaphatikizidwanso ndi kulemera kwa chikwamacho.

Njira yolondola yodziwira ulusi weniweniwo posoka ndikumasula ulusi wa chikho cha chimbudzi ndikulemera, apa timazitenga ngati magalamu atatu.

kotero 100-3 = 97 magalamu

Izi zikutanthauza 20 "x 38.5" Chovala chimalemera magalamu 87.

Tsopano tiyenera kuwerengera gawo la GPM, kuti titha kudziwa kuchuluka kwa matepi kuti zipangidwe, kenako GSM kenako nkukana.

.

Mumvetsetse kuchokera ku njira yoyanjana.

Zindikirani:-Kukula sikusamala kuti muwerengere GPM.

Choncho,

Popeza, kulemera kwa nsalu 38,5 "ndi magalamu 97,

Chifukwa chake, kulemera kwa nsalu 1 "/ 38,5 magalamu,

Chifukwa chake, 39.37 "ya nsalu imalemera = 97 * 39.37) /38.5 magalamu. (39.37 "mu 1 mita)

= 99.19 magalamu

(Ngati galamala ya nsalu iyi ikuyenera kupezeka, ndiye 99.19 / 20 = 4.96 magalamu)

Tsopano GSM ya nsalu iyi imatuluka.

Popeza tikudziwa GPM, timawerengera GSM ndi njira yoyanjana.

Tsopano ngati kulemera kwa 40 "(20x2) ndi 99.19 magalamu.

Chifukwa chake, kulemera kwa 1 "kudzakhala 99.19 / 48 magalamu.

Chifukwa chake kulemera kwa 39.37 kudzakhala = magalamu. (39.37 "mu 1 mita)

Gsm = 97.63 magalamu

Tsopano tengani wotsutsa

Nsalu gsm = (ma mesh arsh + weft mesh) x aniter / 228.6

(Yang'anani kanemayo pofotokozera kuti mudziwe formula)

Denier = Fabric GSM X 228.6 / (Meapp Mesh + Weft Mesh)

=

= 1116 wotsutsa

.

Tsopano tiyeni tiwerenge kuchuluka kwa tepi yomwe iyenera kupangidwa kwathunthu,

Popeza tikudziwa GPM, kenako ndikuwerengera ndi njira imodzi yoyamikizana.

Popeza, kulemera kwa 1 mita ya nsalu ndi 97.63 magalamu.

Chifukwa chake, kulemera kwa 50400 meta / 50400 * 97.63 magalamu

= 4920552 magalamu

= 4920.552 kg

Padzakhala matepi ena atatha pambuyo pa nsaluyo, kotero tepi yowonjezera idzafunika kupangidwa. Nthawi zambiri, kulemera kwa bobin imodzi yotsalira kumatengedwa ngati magalamu 700. Chifukwa chake pano 20 x 2 x 10 x 0.7 = 280 kg zowonjezera. Matepi onse 5200 makilogalamu.

Kumvetsetsa kuwerengera kofanana ndi njira zofananira, muwone vidiyo yomwe idaperekedwa pofotokozera.

Ngati simukumvetsa chilichonse, kenako nenani mu bokosi la ndemanga.
