Manually adjustable ntws tswj hydraulic valve NV08

Cov teeb meem xav tau kev saib xyuas

Raws li qhov muaj peev xwm ntws qis, qhov hloov pauv tau ntawm lub valve yuav txo. Tab sis tsawg kawg nws tuaj yeem lav tau ntawm 10: l thiab 15: 1. Yog hais tias qhov adjustable ratio yog me me, nws yuav nyuaj rau kho qhov ntws.

Thaum cov li qub tau siv nyob rau hauv series, nrog rau kev hloov pauv ntawm qhov qhib, qhov sib txawv ntawm qhov sib txawv ntawm lub hauv ntej thiab sab nraub qaum ntawm lub li qub kuj hloov, uas ua rau cov yam ntxwv ua haujlwm ntawm cov li qub deviate los ntawm cov yam ntxwv zoo tagnrho. Yog hais tias lub kav dej tsis kam yog loj, lub linearity yuav dhau los ua tus cwj pwm qhib ceev, thiab qhov kev hloov pauv yuav ploj mus. Cov yam ntxwv sib npaug feem pua ​​yuav dhau los ua cov yam ntxwv ncaj. Nyob rau hauv cov xwm txheej ntawm cov dej ntws me me, vim tias muaj cov kav dej me me, qhov cuam tshuam ntawm cov yam ntxwv saum toj no tsis zoo, thiab qhov sib npaug feem pua ​​​​ntawm cov yam ntxwv yog qhov tsis tsim nyog. Los ntawm kev tsim khoom, thaum Cv = 0.05 lossis tsawg dua, nws tsis tuaj yeem tsim qhov sib npaug ntawm cov duab sab. Yog li ntawd, qhov teeb meem tseem ceeb rau cov dej ntws me me yog yuav ua li cas tswj cov ntws hauv qhov xav tau.

Los ntawm kev xav txog kev lag luam, cov neeg siv cia siab tias lub valve tuaj yeem siv rau kev cuam tshuam thiab kev tswj hwm, thiab nws tuaj yeem ua tau. Tab sis rau lub regulating valve, nws yog tsuas yog los tswj cov ntws, thiab kaw yog thib ob. Nws yog qhov tsis ncaj ncees lawm uas xav tias qhov ntws ntawm cov dej ntws me me ntawm nws tus kheej yog qhov me me thiab nws yooj yim rau kev paub cuam tshuam thaum nws raug kaw. Cov xau ntawm cov dej ntws me me tswj tau yog feem ntau tswj hwm txawv teb chaws. Thaum tus nqi Cv yog 10, qhov to ntawm lub valve yog txhais li 3.5 kg / cm. Nyob rau hauv cov huab cua siab, qhov to yog tsawg dua 1% ntawm qhov siab tshaj plaws ntws.
