1. Qhov sib txawv ntawm qhov sib txawv: Thaum cov impurities sib sau ua ke rau qee qhov, qhov sib txawv ntawm qhov sib txawv ntawm cov dej txias hauv qhov hluav taws xob thiab cov kav dej yog siv los ntxuav cov dej phwj, uas yog, hluav taws xob tiv tauj lub ntsuas hluav taws xob tig rau ntawm lub teeb liab tswj, lub tshuab tswj. qhib lub qhov hluav taws xob fais fab, thiab hluav taws xob reducer yuav khiav ntawm qhov ceev ntawm 3-6 revolutions ib feeb, thiab ntws mus rau hauv cov dej txias qhov hluav taws xob cov yeeb nkab los ntawm cov kav dej phwj thiab cov kav dej phwj tuaj, thiab kev tu thiab tso dej yuav siv li 5- 10 feeb. Thaum muaj cov khib nyiab loj thiab cov lim dej tsis tuaj yeem txav mus rau hauv qhov chaw, cov khoom siv hluav taws xob yuav tsum khiav mus rau qhov tsis sib xws kom yaug cov khib nyiab.
2. Tus neeg siv tuaj yeem teem sijhawm tawm yog tias xav tau. Lub sijhawm ntxuav thiab tso tawm tuaj yeem teem sijhawm li ntawm 0-99 teev. Feem ntau, nws tau teem kom tso tawm ib zaug txhua 12 teev. Lub sijhawm teeb tsa tuaj yeem hloov kho raws li qhov dej zoo ntawm lub tshuab fais fab. Ntawd yog, lub sijhawm teem sijhawm yog pib lub tshuab hluav taws xob kom thim rov qab lub valve kom qhib lub qhov dej ntws tawm, thiab thim rov qab thim rov qab kom ntws cov dej phwj tuaj. Kom txog rau thaum lub recoil ntawm tag nrho cov chambers tiav, cov khoom siv hluav taws xob tsis ua hauj lwm, hluav taws xob recoil valve thiab hluav taws xob dej phwj valve raug kaw, thiab dej phwj ua hauj lwm tag nrho.
