產(chǎn)品詳情
人工砂替代天然砂成為建筑的主要用砂,機(jī)制砂的需求量就日益劇增,目前機(jī)制砂生產(chǎn)所用的主要設(shè)備是制砂機(jī)。從山上開(kāi)采的石塊經(jīng)顎式破碎機(jī)粗碎之后,進(jìn)入制砂機(jī)進(jìn)行細(xì)碎,細(xì)碎符合標(biāo)準(zhǔn)的砂子被送往石料堆,不符合標(biāo)準(zhǔn)的砂子返回制砂機(jī)繼續(xù)進(jìn)行破碎。有時(shí)候會(huì)出現(xiàn)制砂機(jī)破碎后的砂子粒度過(guò)大,很多不符合標(biāo)準(zhǔn)的砂子,鑫海機(jī)械分析了造成制砂機(jī)產(chǎn)品粒度過(guò)大的原因及解決方法。造成制砂機(jī)產(chǎn)品粒度過(guò)大的原因是三角帶過(guò)松,解決方法是拉緊三角帶。

一般的離心泵葉輪多為此類(lèi)。泵殼作用是將葉輪封閉在一定的空間,以便由葉輪的作用吸入和壓出液體。離心泵殼多做成蝸殼形,故又稱(chēng)蝸殼。由于流道截面積逐漸擴(kuò)大,故從葉輪四周甩出的高速液體逐漸降低流速,使部分動(dòng)能有效地轉(zhuǎn)換為靜壓能。泵殼不僅匯集由葉輪甩出的液體,同時(shí)又是一個(gè)能量轉(zhuǎn)換裝置。離心的概念離心其實(shí)是物體慣性的表現(xiàn).比如雨傘上的水滴,當(dāng)雨傘緩慢轉(zhuǎn)動(dòng)時(shí),水滴會(huì)跟隨雨傘轉(zhuǎn)動(dòng),這是因?yàn)橛陚闩c水滴的摩擦力做為給水滴的向心力使然.但是如果雨傘轉(zhuǎn)動(dòng)加快,這個(gè)摩擦力不足以使水滴在做圓周運(yùn)動(dòng),那么水滴將脫離雨傘向外緣運(yùn)動(dòng).就象用一根繩子拉著石塊做圓周運(yùn)動(dòng),如果速度太快,繩子將會(huì)斷開(kāi),石塊將會(huì)飛出.這個(gè)就是所謂的離心。
