Air compressor kuverenga formula uye musimboti!
Semunhu ari kudzidzira mainjiniya emhepo compressors, pamusoro pekunzwisisa mashandiro echigadzirwa chekambani yako, mamwe maverengero akabatanidzwa muchinyorwa ichi akakoshawo, zvikasadaro, hunyanzvi hwako huchave hwakachenuruka.
(Schematic diagraph, isingaenderane nechero chigadzirwa chiri muchinyorwa)
1. Kutorwa kweshanduko yeyuniti ye "standard square" uye "cubic"
1Nm3/min (standard square) s1.07m3/min
Saka, kutendeuka uku kwakaitika sei?Nezve tsananguro yeyakajairwa sikweya uye cubic:
pV=nRT
Pasi penyika mbiri idzi, kudzvanywa, kuwanda kwezvinhu, uye zvimiro zvakafanana, uye musiyano unongova tembiricha (thermodynamic tembiricha K) inotorwa: Vi/Ti=V2/T2 (ndiko kuti, mutemo weGay Lussac)
Fungidzira: V1, Ti ndiwo akajairwa cubes, V2, T2 macube
Zvadaro: V1: V2=Ti: T2
Kureva: Vi: Vz=273: 293
Saka: Vis1.07V2
Mhedzisiro: 1Nm3/mins1.07m3/min
Chechipiri, edza kuverenga kushandiswa kwemafuta emhepo compressor
Kune mhepo compressor ine 250kW, 8kg, kutamiswa kwe40m3/min, uye nemafuta emukati 3PPM, mangani marita emafuta iyo unit ichashandisa theoretically kana ichimhanya kwemaawa 1000?
mhinduro:
Kushandiswa kwemafuta pa cubic mita paminiti:
3x 1.2=36mg/m3
, 40 cubic metres paminiti kushandiswa kwemafuta:
40×3.6/1000=0.144g
Kushandiswa kwemafuta mushure mekushanda kwemaawa 1000:
-1000x60x0.144=8640g=8.64kg
Yakashandurwa kuita vhoriyamu 8.64/0.8=10.8L
(Kukosha kwemafuta ekuzora anenge 0.8)
Izvo zviri pamusoro ingori theoretical mafuta ekushandisa, muchokwadi yakakura kupfuura kukosha uku (iyo mafuta separator core filter inoramba ichidzikira), kana ikaverengerwa zvichienderana ne4000 maawa, 40 cubic air compressor inomhanya ingangoita 40 malita (madhiramu maviri) yemafuta.Kazhinji, anenge 10-12 mbiya (18 malita / mbiya) inowedzerwa kune imwe neimwe yekuchengetedza ye40-square-mita yemhepo compressor, uye kushandiswa kwemafuta kunenge 20%.
3. Kuverenga kwehuwandu hwegasi remubani
Verenga kutamiswa kwemhepo compressor kubva kubani kuenda kubani:
Citation formula:
V1/V2=R2/R1
V1 = mhepo yemhepo munzvimbo isina chinhu, V2 = mhepo yemhepo munzvimbo yebani
R1=compression ratio ye plain, R2=compression ratio ye plateau
Muenzaniso: Iyo mhepo compressor ndeye 110kW, iyo exhaust pressure ndeye 8bar, uye vhoriyamu yekuyerera iri 20m3/min.Ndekupi kutamiswa kweiyo modhi pakukwirira kwemamita 2000?Bvunza iyo barometric pressure tafura inoenderana nekukwirira)
Mhinduro: Zvinoenderana neformula V1/V2= R2/R1
(label 1 is plain, 2 is plateau)
V2=ViR1/R2R1=9/1=9
R2=(8+0.85)/0.85=10.4
V2=20×9/10.4=17.3m3/min
Zvadaro: vhoriyamu yekupedza yemuenzaniso uyu ndeye 17.3m3 / min pahupamhi hwemamita 2000, zvinoreva kuti kana iyi compressor yemhepo yakashandiswa munzvimbo dzemapani, vhoriyamu yekubuda ichave yakanyanya kuderedzwa.
Naizvozvo, kana vatengi vari munzvimbo dzakatenuka vachida imwe huwandu hwemhepo yakamanikidzwa, ivo vanofanirwa kutarisisa kuti kutamiswa kwemhepo yedu compressor kunogona kuzadzisa zvinodiwa mushure mekukwirira-kwepamusoro attenuation.
Panguva imwecheteyo, vatengi vakawanda vanoisa mberi zvavanoda, kunyanya avo vakagadzirirwa nesangano rekugadzira, nguva dzose vanoda kushandisa chikwata cheNm3 / min, uye vanofanira kubhadhara kutendeuka vasati vaverenga.
4. Kuverenga kwekuzadza nguva yemhepo compressor
Zvinotora nguva yakareba sei kuti air compressor izadze tangi?Kunyangwe kuverenga uku kusinganyanyi kubatsira, hakuna kunyatso kurongeka uye kunogona kungova fungidziro pane zvese.Nekudaro, vashandisi vazhinji vachiri kuda kuyedza nzira iyi kunze kwekukahadzika pamusoro pekutamiswa chaiko kwemhepo compressor, saka pachine akawanda mamiriro ekuverenga uku.
Yekutanga ndiyo musimboti wekuverenga uku: chaizvo ndiko kushandurwa kwevhoriyamu yenzvimbo mbiri dzegasi.Chechipiri ndicho chikonzero chekukanganisa kukuru kwekuverenga: kutanga, hapana mamiriro ekuyera mamwe data anodiwa panzvimbo, zvakadai sekushisa, saka inogona kungoregererwa;chechipiri, kushanda chaiko kwechiyero hakugone kuve kwakarurama, sekuchinjira kuChimiro cheKuzadza.
Nekudaro, kunyangwe zvakadaro, kana paine chinodiwa, isu tichiri kuda kuziva kuti ndeupi nzira yekuverenga:
Muenzaniso: Zvinotora nguva yakareba sei kuti 10m3/min, 8bar air compressor izadze 2m3 gasi rekuchengetedza gasi?Tsanangudzo: Chii chakazara?Izvi zvinoreva kuti, iyo compressor yemhepo yakabatana ne2 cubic metres yekuchengetedza gasi, uye gasi rekuchengetedza kupera kwevhavhavhavha Ivhare kusvika iyo compressor yemhepo yarova 8 bar kuti ibudise, uye geji yekumanikidza yebhokisi rekuchengetedza gasi zvakare 8 bar. .Nguva iyi inotora nguva yakareba sei?Ongorora: Ino nguva inoda kuverengerwa kubva pakutanga kurodha mhepo compressor, uye haigone kusanganisira yapfuura nyeredzi-delta shanduko kana maitiro eiyo frequency kumusoro-shanduko ye inverter.Ichi ndicho chikonzero kukuvara chaiko kwakaitwa pasaiti hakugone kuve kwakarurama.Kana paine nzira yekunzvenga mupombi yakabatana nemhepo compressor, kukanganisa kunenge kuri kudiki kana mweya compressor yazara uye nekukasira kuchinjirwa kune pombi yekuzadza tangi yekuchengetera mhepo.
Kutanga nzira iri nyore (fungidziro):
Pasina kutarisisa tembiricha:
piVi = pzVz (Boyle-Malliot Law) Kuburikidza neiyi fomula, inowanikwa kuti shanduko yehuwandu hwegasi ndiyo chaiyo yekumanikidza reshiyo.
Zvadaro: t=Vi/ (V2/R) min
(Nhamba yekutanga ndiyo vhoriyamu yetangi yekuchengetedza mweya, uye 2 ndiyo vhoriyamu inoyerera yemhepo compressor)
t=2m3/ (10m3/9) min= 1.8min
Zvinotora anenge maminetsi 1.8 kubhadharisa zvizere, kana ingangoita 1 miniti uye 48 masekonzi
ichiteverwa nealgorithm yakati kuomarara
kune gauge pressure)
tsanangura
Q0 - Compressor vhoriyamu kuyerera m3/min pasina condensate:

Tk - tembiricha yegesi K mutangi.
5. Kuverenga Kwemhepo Kushandiswa kwePneumatic Tools
Iyo mhepo yekushandisa yekuverenga nzira yemhepo sosi sisitimu yechinhu chimwe nechimwe chepneumatic kana ichishanda nekupindirana (kushandiswa nekukasira uye kumira):
Qmax- iyo chaiyo yakanyanya kushandiswa kwemhepo inodiwa
Chikomo - kushandiswa chinhu.Inofunga nezve coefficient iyo yose michina yepneumatic haizoshandisi panguva imwe chete.Iyo empirical kukosha ndeye 0.95 ~ 0.65.Kazhinji, kuwanda kwenhamba yemidziyo yepneumatic, kushomeka kwekushandisa panguva imwe chete, uye kudiki kukosha, zvikasadaro iyo yakakura kukosha.0.95 yemidziyo miviri, 0.9 yezvishandiso zvina, 0.85 yemidziyo mitanhatu, 0.8 yemidziyo misere, uye 0,65 yezvishandiso zvinopfuura gumi.
K1 - Leakage coefficient, kukosha kunosarudzwa mukati kubva 1.2 kusvika 15
K2 - Spare coefficient, kukosha kunosarudzwa muhuwandu hwe1.2 ~ 1.6.
K3 - Coefficient isina kuenzana
Inofunga kuti pane zvinhu zvisina kuenzana mukuverenga kweavhareji gasi rinoshandiswa mugasi sosi system, uye inotarwa kuti ive nechokwadi chekushandiswa kwakanyanya, uye kukosha kwayo kuri 1.2
~ 1.4 Fan kusarudzwa kwemumba.
6. Kana huwandu hwemhepo husina kukwana, verenga musiyano wehuwandu hwemhepo
Nekuda kwekuwedzera kwemidziyo yekushandisa mhepo, mhepo inopihwa haina kukwana, uye yakawanda sei mweya compressors inoda kuwedzerwa kuchengetedza yakayerwa kushanda kumanikidza kunogona kugutsikana.formula:
Q Chaiyo - iyo mhepo compressor kuyerera mwero inodikanwa nehurongwa pasi peiyo chaiyo mamiriro,
QOriginal - mwero wekuyerera kwevatyairi yeiyo yekutanga mweya compressor;
Pact - iyo yekumanikidza MPa iyo inogona kuwanikwa pasi pemamiriro chaiwo;
P yepakutanga - iyo inoshanda yekumanikidza MPa iyo inogona kuwanikwa nekushandiswa kwepakutanga;
AQ- volumetric kuyerera kunowedzera (m3/min)
Muenzaniso: Yepakutanga air compressor ndeye gumi cubic metres uye 8 kg.Mushandisi anowedzera zvishandiso uye ikozvino mhepo compressor pressure inogona kungorova 5 kg.Bvunza, ingani mhepo compressor inoda kuwedzerwa kuti isangane nemhepo inoda 8 kg.
AQ=10* (0.8-0.5) / (0.5+0.1013)
s4.99m3/min
Naizvozvo: mhepo compressor ine kutama kweinenge 4.99 cubic metres uye 8 kilogiramu.
Muchokwadi, musimboti weformula iyi ndewekuti: nekuverenga mutsauko kubva pakumanikidzwa kwainotarirwa, inoverengera chikamu chekumanikidza kwazvino.Chiyero ichi chinoshandiswa kuhuwandu hwekuyerera kweiyo ikozvino inoshandiswa air compressor, ndiko kuti, kukosha kubva kune chinangwa chekuyerera kunowanikwa.
