螺旋擠漿機(jī)是制漿造紙廠黑液綜合利用理想的提取設(shè)備,用于木,竹,蔗渣,麥草,蘆葦?shù)葹樵系募垵{黑液提取,同時(shí)也可用于廢紙脫黑漿的黑液提取。由于螺旋擠漿機(jī)在運(yùn)轉(zhuǎn)過程中受到的軸向力特別大,所以容易導(dǎo)致軸承的損壞,進(jìn)而造成軸承位的磨損。傳統(tǒng)維修方法是拆卸設(shè)備,補(bǔ)焊后機(jī)加工,但是補(bǔ)焊高溫產(chǎn)生的熱應(yīng)力無法完全消除,或?qū)S承位進(jìn)行鑲套處理,費(fèi)時(shí)費(fèi)力,也無法保證良好的配合。當(dāng)前,發(fā)達(dá)國家針對上述設(shè)備問題多采用高分子復(fù)合材料進(jìn)行現(xiàn)場維修,其中應(yīng)用成熟的有美嘉華技術(shù)體系。相對傳統(tǒng)方法,該維修方式可以做到免拆卸、免機(jī)加工現(xiàn)場修復(fù),維修費(fèi)用低、周期短、大大減輕了維修人員勞動(dòng)強(qiáng)度。同時(shí)由于材料具有優(yōu)異的綜合機(jī)械性能和粘著力,不會產(chǎn)生高溫應(yīng)力,完全滿足設(shè)備運(yùn)行要求,可確保軸承室與軸承的良好配合,避免再次出現(xiàn)間隙的可能。
Spiral squeeze pulp machine is an ideal equipment for comprehensive utilization of black liquor in pulp and paper mills. It can be used to extract black liquor from wood, bamboo, bagasse, wheat straw, reed and other raw materials. It can also be used to extract black liquor from deinking pulp of waste paper. Because the axial force of the spiral squeeze pulp machine in operation is very large, it is easy to cause bearing damage, and then cause bearing wear. The traditional maintenance methods are dismantling equipment and machining after repair welding, but the thermal stress caused by high temperature of repair welding can not be completely eliminated, or the bearing position is treated by insertion, which is time-consuming and laborious, and can not guarantee good coordination. At present, the developed countries mostly use polymer composites for on-site maintenance to solve the above equipment problems, among which the mature Megawa technology system is applied. Compared with the traditional method, this maintenance method can achieve on-site repair without disassembly and machining. It has the advantages of low maintenance cost and short cycle,and greatly reduces the labor intensity of maintenance personnel. At the same time, because the material has excellent comprehensive mechanical properties and adhesion force, it will not produce high temperature stress, fully meet the requirements of equipment operation, can ensure good coordination between bearing chamber and bearing, and avoid the possibility of re-emergence of clearance.
