由破碎機(jī)的正常操作產(chǎn)生的振動(dòng)能量不足以導(dǎo)致基板破裂。 主要是由于破碎機(jī)運(yùn)行中的不穩(wěn)定因素:如果破碎機(jī)的破碎腔嚴(yán)重堵塞,將產(chǎn)生機(jī)械振動(dòng),這將對(duì)基板產(chǎn)生大影響。 在許多類似的振動(dòng)之后,可能發(fā)生基礎(chǔ)斷裂。 破碎機(jī)鉗口是原始的或已經(jīng)過改造,這也會(huì)導(dǎo)致顎式破碎機(jī)在操作過程中不均勻地加載,扭曲和擺動(dòng),導(dǎo)致顎式破碎機(jī)底座破裂。 顎式破碎機(jī)經(jīng)歷基礎(chǔ)破裂并且經(jīng)受簡單的焊接或焊接缺陷,因此機(jī)器可能在正常操作期間導(dǎo)致基座破裂。

破碎機(jī)底座破裂的解決方案:一般簡單的維護(hù)是焊接修復(fù),但這種修復(fù)的效果并不理想。 在準(zhǔn)備大修時(shí),顎式破碎機(jī)的整個(gè)底座可以用鋼板焊接。 大直徑高強(qiáng)度錨固件嵌入混凝土基礎(chǔ)中,即使破碎機(jī)堵塞,顎式破碎機(jī)底座也不會(huì)對(duì)振動(dòng)產(chǎn)生不利影響。 如果顎式破碎機(jī)容易發(fā)生異常振動(dòng),請(qǐng)考慮調(diào)整顎板。 由于軸承磨損嚴(yán)重,可以打破顎式破碎機(jī)底座以換軸承。 如果顎式破碎機(jī)太松或太緊,可以換顎式破碎機(jī)。 換堅(jiān)固的底座,以防止類似的故障再次發(fā)生。
在正常運(yùn)行中早期檢測(cè)對(duì)輥破碎機(jī)故障早已為人所知,并且這種預(yù)防性工作可以大大減少生產(chǎn)中的停機(jī)時(shí)間,從而大大提高生產(chǎn)效率。 要在不停機(jī)的情況下監(jiān)控故障,首先要了解對(duì)輥破碎機(jī)正常運(yùn)行時(shí)機(jī)器的各種運(yùn)行參數(shù)。 它包括操作過程中產(chǎn)生的對(duì)輥破碎機(jī)數(shù)量,機(jī)器運(yùn)行期間的聲音以及運(yùn)行期間的活動(dòng)狀態(tài)。 只有了解這些基本狀態(tài),才能及時(shí)發(fā)現(xiàn)機(jī)器的異常。 根據(jù)機(jī)器的正常狀態(tài)數(shù)據(jù),我們還需要了解某些機(jī)器異常時(shí)的特性。
破碎機(jī)生產(chǎn)中的振動(dòng)現(xiàn)象需要控制在合理的范圍內(nèi),否則會(huì)產(chǎn)生大的噪聲,造成環(huán)境污染,大的振動(dòng)也會(huì)影響機(jī)器的生產(chǎn),如生產(chǎn)的下降。 因此,在機(jī)器的使用中,如何減少振動(dòng)是亟待解決的問題。 這是減少破碎機(jī)振動(dòng)的三種有效措施。

要做到這一點(diǎn),首先需要將破碎機(jī)安裝在堅(jiān)硬,穩(wěn)定的地板上。 否則,經(jīng)過長時(shí)間的工作,基礎(chǔ)會(huì)掉落,引起振動(dòng)并安裝機(jī)器。 在此過程中,遵循科學(xué)合理的程序。 在固定破碎機(jī)時(shí),鋪設(shè)基礎(chǔ),并在以后使用時(shí)檢查基礎(chǔ)是否松動(dòng)。 如果松動(dòng),應(yīng)及時(shí)加強(qiáng);
 這主要是為了檢查破碎機(jī)的固定螺栓和螺釘?shù)染o固件是否松動(dòng)。 如果發(fā)生松動(dòng),及時(shí)收緊。 另外,如果飛輪的位置在生產(chǎn)過程中偏離,除了上述方面之外,還需要在破碎機(jī)的生產(chǎn)過程中定期檢查軸承間隙。 在生產(chǎn)中,應(yīng)進(jìn)行軸承潤滑以減少軸承造成的損壞。 由此產(chǎn)生的振動(dòng)現(xiàn)象;
具有與調(diào)節(jié)墊相同的墊間距和相同尺寸的傳送帶用作緩沖墊,以減小擺動(dòng)壓力并減小一定范圍內(nèi)的振動(dòng)以防止破損。 當(dāng)機(jī)器調(diào)節(jié)墊抬起時(shí),需要在調(diào)節(jié)墊上焊接兩個(gè)壓力板。 此外,如果破碎機(jī)主軸在生產(chǎn)過程中不平衡或長時(shí)間過載,主軸將嚴(yán)重彎曲。 變形,造成設(shè)備振動(dòng),此時(shí)的解決方案是及時(shí)糾正主軸,如果不能糾正,及時(shí)換新主軸;
