Qhov zoo ntawmnpauj npaim valve
Npauj npaim li qub zoo ib yam li pob li qub, tab sis muaj ntau yam zoo. Lawv yog me me thiab, thaum actuated pneumatically, tuaj yeem qhib thiab kaw sai heev. Lub disc yog sib dua li lub pob, thiab lub valve yuav tsum muaj kev txhawb nqa tsawg dua li lub pob valve ntawm txoj kab uas hla. Npauj npaim li qub yog qhov tseeb heev, uas ua rau lawv muaj txiaj ntsig zoo hauv kev lag luam. Lawv ntseeg tau heev thiab yuav tsum tau saib xyuas me ntsis.

Disadvantages ntawm npauj npaim valve
Ib qho tsis zoo ntawm npauj npaim li qub yog tias qee qhov ntawm cov disc yeej ib txwm nyob hauv qhov ntws, txawm tias thaum qhib tag nrho. Yog li ntawd, siv lub npauj npaim valve yuav ib txwm tsim lub siab hloov ntawm lub valve, tsis hais qhov chaw.

Hluav taws xob, Pneumatic lossis Manually Operated Npauj Npaim li qub

Npauj npaim li qubtuaj yeem teeb tsa rau phau ntawv, hluav taws xob lossis pneumatic ua haujlwm. Pneumatic li qub ua haujlwm ceev tshaj plaws. Hluav taws xob li qub yuav tsum tau xa cov teeb liab mus rau lub gearbox kom qhib lossis kaw, thaum pneumatic li qub tuaj yeem ua tau ib leeg lossis ob-actuated. Ib leeg-actuated li qub feem ntau yog teeb tsa kom xav tau lub teeb liab qhib nrog tsis muaj kev nyab xeeb, uas txhais tau hais tias thaum lub zog poob, lub valve springs rov qab mus rau qhov chaw kaw tag nrho. Dual actuated pneumatic li qub tsis yog lub caij nplooj ntoos hlav loaded thiab xav tau lub teeb liab qhib thiab kaw.

Automated pneumatic npauj npaim li qub yog txhim khu kev qha thiab ruaj khov. Txo kev hnav txhim kho lub voj voog lub neej ntawm lub valve, yog li txo cov nqi khiav lag luam uas yuav tsis ua haujlwm poob hauv cov sij hawm ua haujlwm tswj lub valve.
