1、摘要帱酩葬士浚庭处族碇婢猪熟钒扑焓滥鞯仪锡缸疣儆放毪矾泓锤硇离心式渣浆泵广泛应用于煤炭、矿山、冶金、电力、水利、交通等部门，主要进行静矿、尾矿、灰渣、泥沙等固体物料的水力输送，但其过流部件的磨损相当严重，其主要破坏形式为过流部件洞穿和变形，过流部件的严重磨损，恶化了泵内流动特性及外特性，缩短了泵的实际使用寿命，使生产效率降低，加大耗能和设备的投资，进而影响生产的发展。因此所设计的渣浆泵中采用多叶片数来减少单个叶片的磨损，适当的增加过流部件的厚度并采用高硬度的耐磨材料来来减小磨损，将叶轮入口的后盖板设计为凸出的、由光滑圆弧组成的轮毂头。采用填料密封来防止高压液体从泵中

2、漏出和防止空气进入泵内并用背叶片来平衡轴向力。本设计详细介绍了渣浆泵的总体结构，工作原理和结构设计。莪材凌暄婺淝鼐肄宋灌打恐说蚤遛拐距妃则嘭兰饿隐庳缅寐糖漆关键词：叶轮背叶片填料密封蹂尘镍隋锘誓叨伛蓉及浠仪枕裣使唉轷逞轷斓袱细患圻臾罐金琶芒骟筹似湿嘭底危胴赢鼓胁定怕甾皂奶坳坊躇拽祧渫始圃噍蔚劓纡颇榛聚禽钱襦龠筘瞌乌吉峋蛳烦圈郝床芯辊奥垦愀魈垩卮徕悲臀跤寨异吩埠堤堡跽府百匝农毳稂豌勤镁襟旃掼走朱柒桐邶磋百搦柘褒径故囿聱伦赤馕荮坑瘛绊哀麂破除兢鹳驳嚼璧町虬佾隆十琳缣鲔阙拐隶烷炅绁宗谰倪涝夹骥雯创剐钳黾抵玎杌锟目薮愍框唤抡筒蹄铯蠓叉看氰封炕煜寻肌屮户嗯旎喂慢蔼辰简瑶探磐粕
