    Research has to focus on the cost benefit of factors such as reliability. As reliability increases, manufacturing costs and the final cost of the system will decrease. Having 30 percent junk at the end of a production line not only costs a fortune but also creates an opportunity for a competitor to take your idea and sell it to your customers.
    Central to the process of improving reliability and lowering costs is the intensive and widespread use of design software, which allows engineers to speed up every stage of the design process. Shortening each stage, however, may not sufficiently reduce the time required for the entire process. Shortening each stage, however, may not sufficiently reduce the time required for the entire process. Therefore, attention must also be devoted to concurrent engineering software with shared databases that can be accessed by all members of the design team.
    As we move more fully into the Information Age, success will require that the engineer possess some unique knowledge of and experience in both the development and the management of technology. Success will require broad knowledge and skills as well as expertise in some key technologies and disciplines; it will also require a keen awareness of the social and economic factors at work in the marketplace. Increasingly, in the future, routine problems will be expected to work cooperatively in solving more challenging, more demanding problems in substantially less time. We have begun a new phase in the practice of engineering. It offers great promise and excitement as more and more problem-solving capability is placed in the hands of the computerized and wired engineer. To assure success, the capability of our tools and the unquenched thirst for better products and systems must be matched by the joy of creating that marks all great engineering endeavors. Mechanical engineering is a great profession, and it will become even greater as we make the most of the opportunities offered by Information Age.
    疏磨机设计
       随着现代造纸工业的发展,废纸的再生利用(废纸的回收与循环再利用)已有所普及,一则可以降低生产成本,二则能减少环境污染,节约设备投资,提高资源利用率,因此,及时跟进先进的废纸处理配套设备尤为重要。作为废纸处理系统(碎解设备、筛选净化设备或热分散)中浆料的后续疏解设备,是现代造纸生产中不可缺少的设备之一,其目的是将废纸经碎解、筛选、净化或热分散后未完全消失的纸片或纤文团在不切断损伤与降低强度的前提下离解或分散成单根的、润湿的、相当纤文化的纤文,以降低废纸处理系统的运行能耗,提高生产能力与废纸浆质量,更利于后续磨浆、抄造。
    疏解机是用于废纸制浆工厂由处理工艺包括减小废纸浆粗细和去除杂质。确切的过程取决于纸浆的类型和所要生产的纸的特性。当到达造纸机时,纸浆应该分散细小。
    如果成浆直接从生原料,例如:化学浆料、废纸或者碎纸浆中产生。那么纸浆直接从造纸机中得到,直到产生可以使用的程度为止。这种情况在现代造纸业中是不经济的。纸浆在疏解机的作用下达到最小的纤文程度。这种制浆方法达到了最好的能源节约。论文网
    疏解机中最著名的是埃舍尔文斯设计发明的疏解机,这种疏解机可以在复杂的工作条件下运行。迄今为止已经有2000多台疏解机应用在企业中。在实际运行中,这类疏解机已经被证明是高效且安全的。
    以下是疏解机的优点:
        对纸浆的完全疏解
        容易运行
        适应各类场合
        纸浆的游离度降低
        节省能源
    疏解机类型的选择:
    1.    浆料在机器中有良好的游离性,并且能得到充分疏解。
