煤礦機(jī)械屬于機(jī)械的一個(gè)大的分類，主要指用于煤礦的采掘、支護(hù)、運(yùn)輸、洗選等生產(chǎn)過程的礦 山機(jī)械。煤礦機(jī)械由于其專業(yè)特點(diǎn)而不同于其他礦山機(jī)械。作為煤炭生產(chǎn)的大國，煤礦機(jī)械的生產(chǎn)在我 國有著舉足輕重的作用。東晟密封生產(chǎn)的：鼓型圈、山型圈、蕾型圈、防塵圈等都是煤礦液壓支架里十 分重要的密封元件，缺一不可！         Coal mining machinery belongs to a large classification of machinery, mainly refers to mining machinery used in digging, supporting, transportation, washing and other production processes. Coal mining machinery is different from other mining machinery due to its professional characteristics. As a big country in coal production, the production of coal mining machinery plays a decisive role in China. Drum ring, piston seals SH, bud ring, wiper seals, etc. produced by DSH Seals are all important and indispensable sealing components in coal mining hydraulic support.
