毕业设计（论文）-离心泵的设计及其密封（含图纸） 题目 离心泵的设计及其密封 摘要：在当今社会离心泵的应用是很广泛的,在国民经济的许多部门要用到 它。在给系统中几乎是不可缺少的一种设备/h的离心泵。电机功率为7.5kw，转 速为2900r/min，.在0―80C工作环境下输送带杂质液体的离心泵的机械密封。 关键词： 泵填料密封 离心泵 机械密封 Centrifugal pump design and sealing Abstract: In today's society, the centrifugal pump is applied widely in the national economy, many departments should use it. In the supply system is almost an indispensable equipment. The practical application in pump industry, especially with serious loss in actual application of pump shaft seals, mainly is loss in the process of conveying, due to improper seal leakage caused heavy losses and accidents. Shaft seals have packing seal and mechanical seal. Packing seal use short cycle, the loss is high. Efficiency is low. This design USES mechanical seal. Mainly in their design based on centrifugal pump, and the improved seal pump, in order to reduce loss, improve the centrifugal pump life. This design is the main content of work, design ahead for 40 MB, flow 100m/h of centrifugal pump. Electric power is 7.5 kw, speed for 2900r/min, the 0-80 Cwork
