Qhov zoo thiab qhov tsis zoo ntawm cov hluav taws xob li qub thiab pneumatic li qub

Pneumatic li qub

Lub actuator thiab kev hloov kho mechanism ntawm pneumatic actuator yog kev sib koom ua ke thiab cov actuators yog hom diaphragm thiab hom piston. Lub piston stroke ntev yog tsim rau cov ntawv thov uas xav tau lub zog loj; lub diaphragm stroke yog me me thiab tsuas yog ncaj qha tsav lub valve qia. Vim hais tias lub pneumatic actuator muaj qhov zoo ntawm cov qauv yooj yim, cov zis tawm loj, ruaj khov thiab txhim khu kev qha, thiab kev nyab xeeb thiab tawg-pov thawj, nws yog dav siv hauv cov nroj tsuag hluav taws xob, tshuaj lom neeg kev lag luam, roj refining thiab lwm yam txheej txheem ntau lawm nrog kev ruaj ntseg siab.

Lub ntsiab zoo ntawm pneumatic actuators:

1. Txais cov teeb liab hluav taws xob txuas ntxiv thiab tso zis tawm tawm (nruam hluav taws xob teeb liab tuaj yeem tau txais tom qab lub zog hluav taws xob / roj hloov khoom siv). Qee tus tuaj yeem nruab nrog angular arm displacement tom qab tso tawm lub caj npab rocker.

2. Muaj kev ua haujlwm zoo thiab tsis zoo.

3. Kev txav ceev yog loj, tab sis qhov ceev yuav qeeb dua thaum lub load nce.

4. Lub zog tso zis muaj feem xyuam rau kev khiav hauj lwm siab.

5, muaj kev ntseeg siab, tab sis lub valve tsis tuaj yeem tswj xyuas tom qab lub qhov hluav taws xob cuam tshuam (tuaj yeem khaws cia tom qab lub valve tuav).

6. Tsis yooj yim rau kev siv segmentation tswj thiab kev tswj cov kev pab cuam.

7, yooj yim txij nkawm thiab adaptability rau ib puag ncig.

8, lub zog tso zis yog loj.

9, nrog rau kev tawg-pov thawj muaj nuj nqi.

Hluav taws xob valve

Cov hluav taws xob actuators feem ntau yog siv rau hauv cov chaw tsim hluav taws xob lossis cov chaw tsim hluav taws xob nuclear vim tias xav tau cov txheej txheem du, ruaj khov thiab qeeb hauv cov dej siab. Lub ntsiab zoo ntawm cov hluav taws xob actuator yog lub siab ruaj khov thiab qhov thrust tas li uas tus neeg siv tuaj yeem thov. Lub thrust generated los ntawm tus actuator loj tuaj yeem siab li 225000kgf. Tsuas yog lub hydraulic actuator tuaj yeem ua tiav qhov kev sib tw loj, tab sis tus nqi ntawm hydraulic actuator yog siab dua qhov ntawd. Cov hluav taws xob ntau dua. Lub peev xwm los tiv thaiv kev sib txawv ntawm cov hluav taws xob actuator yog qhov zoo heev. Lub thrust lossis torque ntawm cov zis yog qhov tseem ceeb, uas tuaj yeem kov yeej qhov tsis sib xws ntawm qhov nruab nrab thiab ua tiav kev tswj xyuas cov txheej txheem tsis raug. Yog li ntawd, kev tswj qhov tseeb yog zoo dua li ntawm pneumatic actuator. siab. Yog tias siv lub servo amplifier, nws yog ib qho yooj yim kom ua tiav qhov kev sib pauv ntawm qhov zoo thiab qhov tsis zoo, thiab nws kuj yog ib qho yooj yim los teeb lub xeev ntawm lub teeb liab valve txoj hauj lwm (tuav / full-open / full-off), thiab thaum twg Nws yog faulty, nws yuav tsum nyob rau hauv qhov chaw, qhov no yog Pneumatic actuators tsis, pneumatic actuators yuav tsum tau ruaj ntseg los ntawm ib tug ua ke tiv thaiv system.

Lub ntsiab tsis zoo ntawm hluav taws xob actuators yog:

Cov qauv yog qhov nyuaj dua, nws yooj yim dua rau kev ua tsis tiav, thiab vim nws txoj kev nyuaj, cov kev xav tau rau cov neeg ua haujlwm saib xyuas ntawm qhov chaw yog siab dua; lub cev muaj zog khiav los ua kom muaj cua sov, yog tias qhov kev hloov kho ntau dhau, nws yooj yim ua rau lub cev muaj zog thiab ua kom muaj kev tiv thaiv thermal. Nws tseem yuav ua rau kom muaj kev hnav ntawm qhov txo qis; Tsis tas li ntawd, nws yuav khiav qeeb, thiab nws yuav siv sij hawm ntev los tso tawm cov teeb liab los ntawm cov regulator thiab txav mus rau qhov chaw sib thooj hauv cov lus teb rau lub valve. Qhov no tsis zoo li pneumatic lossis hydraulic actuation. Qhov chaw ntawm lub cuab yeej.
