這兩種調速方法主要區(qū)別是在變頻器輸出頻率上,當變頻器輸出頻率時是恒轉矩調速,當變頻器輸出頻率時是恒功率調速。
恒功率調速主要特點是電機產(chǎn)生的轉矩要以和頻率成反比的線性關系下降。其工作原理是:物料由進料口進入碎石機,在碎石機頂部由溢料裝置將物料分為兩部分,一部分經(jīng)溢料口進入破碎腔,另一部分直接進入轉子,物料以50-80m/s的速度從轉子內三個均布的流道口發(fā)射出去,與溢料流發(fā)生碰撞,然后一起沖向破碎腔內的物料墊,被物料墊反彈,斜向上沖擊到破碎腔的頂部,又改變其運動方向,偏向下運動,與溢流石料重新組合,這樣每塊物料在破碎腔內受到兩次甚至多次破碎作用,而后從破碎腔落下由排料口排出。從客戶訪問圓錐碎石機或者歐版顎式碎石機的頁面到客戶主動打或者在線咨詢的這個過程,在網(wǎng)頁設計時要考慮到如何引導訪客逐級了解碎石機產(chǎn)品這也是網(wǎng)絡營銷的一部分。通利槍彈碎石機的特點槍彈碎石機的刀片是用高合金精制而成的嚙合式刀片,對任何高硬度的物料有著很好的碎石機效果。
槍彈碎石機減速電機驅動,比其他槍彈碎石機要省的電量。在一股較強冷空氣的影響下,霧霾終于漸漸散去,然而資本市場上關于大氣污染治理環(huán)境保護新能源概念等卻成為投資者持續(xù)關注的熱點。天藍地綠山青水凈是人們對美麗中國最樸素的理解,這一點在資本市場表現(xiàn)得淋漓剛好。硬度在莫氏七級以下,溫度以下。
