MPLA310FSK72AA伺服電機盡責(zé)善仁
三位四通電磁閥包含兩個線圈,PLC或者其他系統(tǒng)的兩個輸出點控制兩個線圈,即一個線圈通電時打開或關(guān)閉,另一個線圈通電時動作正好相反,沒有電磁閥輸出則保持原態(tài),兩個線圈不可以同時通電;這種電磁閥適用于行程較大的機械結(jié)構(gòu)中且需要位置傳感器配合使用。zui常見的電磁閥為以上幾種,除此之外還有一些特殊的電磁閥,比如說四通閥五通閥等等,它們都有各自的用途,但舉一反三,學(xué)會原理后融會貫通就可以正確的使用它們??偨Y(jié)一下:閥芯會有幾個位置就是幾位閥;閥體上有幾個出口就是幾通閥,這樣理解起來會很方便。
下面就簡單的介紹一下制砂生產(chǎn)線工藝中的三種制砂工藝。砂生產(chǎn)線之濕法生產(chǎn);濕法制砂生產(chǎn)線是指三級破碎段全部采用濕法制砂生產(chǎn)線工藝。其特點是:可以有效的保證人工骨料成品質(zhì)量,對石粉含量和含泥量可控制,降低了生產(chǎn)過程中的粉塵量,但系統(tǒng)用水量大,運行成本高,部分細(xì)砂,石粉流失,回收率較低,廢水處理量大而且效果不太理想。另外,若進入立軸沖擊式破碎機的骨料含水率超標(biāo),容易導(dǎo)致破碎腔結(jié)塊堵塞,降低設(shè)備成砂率,甚至發(fā)生轉(zhuǎn)子抱死的機械事故。干法制砂生產(chǎn)線干法制砂生產(chǎn)線是指幾個破碎段全部采用干式生產(chǎn)工藝。其特點是:無供水裝置。生產(chǎn)工藝簡化,可節(jié)約系統(tǒng)建造投資和運行成本,但對巖石中的泥土含量難以控制,而且系統(tǒng)粉塵污染嚴(yán)重。干法制砂生產(chǎn)線半干法制砂生產(chǎn)線結(jié)合了濕法制砂生產(chǎn)線和干法制砂生產(chǎn)線的優(yōu)點,即粗碎采用濕法生產(chǎn),可有效去除原料中的泥土,降低粉塵排放;中細(xì)碎和中碎(僅有兩個破碎段)采用干法生產(chǎn),棒磨機制砂采用濕法生產(chǎn),通過洗砂與脫水工藝調(diào)節(jié)成品砂的細(xì)度模數(shù)、石粉含量及含水率。

PLC
處理器(CPU)由控制器、運算器和寄存器組成并集成在一個芯片內(nèi)。CPU通過數(shù)據(jù)總線總線、地址總線、控制總線和電源總線與存儲器、輸入輸出接口、編程器和電源相連接。
小型PLC的CPU采用8位或16位微處理器或單片機,如8031、M68000等,這類芯片價格很低;中型PLC的CPU采用16位或32位微處理器或單片機,如8086、96系列單片機等,這類芯片主要特點是集成度高、運算速度快且可靠性高;而大型PLC則需采用高速位片式微處理器。
CPU按照PLC內(nèi)系統(tǒng)程序賦予的功能指揮PLC控制系統(tǒng)完成各項工作任務(wù)
