style="text-indent:25px">回訊器構(gòu)造分為三類：1、活塞型：根據(jù)密封方法不同，有表中的A型和B型2個(gè)種類。A型是用O型環(huán)或薄膜密封的，由于密封橡膠沒有外露，在**工作機(jī)械的切割碎屑方面功能較強(qiáng)大，但其反面影響是，有可能會(huì)將砂子、切割粉末等壓入活塞的滑動(dòng)面。B型雖然不會(huì)把砂子、切割粉末等壓入，且密封性能優(yōu)于A型，但由于熾熱的切割碎屑飛濺過來，有可能會(huì)損壞橡膠帽。因此，要根據(jù)使用場(chǎng)所的不同選用A型或B型。而柱塞型仍然通過柱塞的往復(fù)運(yùn)動(dòng)壓縮或吸進(jìn)空氣。為此，如果長(zhǎng)時(shí)間將柱塞壓入，回訊器內(nèi)的壓縮空氣逸失，內(nèi)部壓力將與大氣壓相同，即使急于讓柱塞復(fù)位，柱塞卻有遲緩復(fù)位的傾向。為了避免發(fā)生這種故障，設(shè)計(jì)時(shí)，根據(jù)柱塞的壓入將空氣的壓縮量控制在回訊器內(nèi)部全部空氣量的20%以內(nèi)。另外，為了延長(zhǎng)微動(dòng)開關(guān)的壽命，在這一構(gòu)造內(nèi)部設(shè)置了一個(gè)OT吸收機(jī)構(gòu)，該OT吸收機(jī)構(gòu)采用OT吸收彈簧，用以吸收殘余的柱塞的行程，安徽機(jī)械式回訊器供應(yīng)商。該機(jī)構(gòu)相對(duì)于柱塞的運(yùn)動(dòng)，在中途停止按壓微動(dòng)開關(guān)輔助柱塞的行程。2、鉸鏈擺桿型：在擺桿端部(滾珠)，柱塞的行程量根據(jù)擺桿的比例擴(kuò)大，安徽機(jī)械式回訊器供應(yīng)商，因此，安徽機(jī)械式回訊器供應(yīng)商，一般不使用OT吸收機(jī)構(gòu)。3、旋轉(zhuǎn)擺桿型回訊器會(huì)在出現(xiàn)故障的時(shí)候停止導(dǎo)電。安徽機(jī)械式回訊器供應(yīng)商</p><div
