渣浆泵和压缩机的发展简介

最早提出离心泵概念的是法国工程师Papin,他在1689年发明了可以称之为离心泵雏形的一种机器，并于1750年制造了第一台适用于提升液体的泵。该泵采用了多叶片的叶轮和蜗形体的泵壳。法国著名数学家欧拉于1750年对离心泵的流动进行了理论分析，为离心泵的发展奠定了基础。1818年作为离心泵发展史上一个转折点，在美国的Massachusetts开始批量生产离心泵。1851 年Jamee Stu Grwme在英国获得多级离心泵发明专利，英国科学家J.Tomsom采用导叶来提高泵的效率。20世纪初在蒸汽轮机的全盛时期,泵几乎全是往复式的。1904年KSB公司提供了锅炉绘水用高压离心系系列1905年苏尔寿兄弟工厂开始了多级串联高压泵的批量生产。

随着机械制造技术和计算机技术的应用，泵在世界各国得到了很大发展。目前世界上泵产品的种类已达5000多种，泵类产品在大容量、高转速高效率、自动化和可靠性方面达到了新的水平。在泵的理论研究方面，多采用计算流体力学方法模拟实际流动，分析流动损失。同时金属材料和非金属材料在泵行业得到了广泛的应用,有效地提高了泵的耐腐蚀、耐磨损、耐高低温和耐冲击的能力。由于环保和安全要求,泵的可靠性和低泄漏量的要求也不断提高。普通的机械密封已接近发展的极限,磁力驱动泵和磁力联轴器得到了迅速发展。同时磁流体密封技术则有取代磁力驱动泵和双端面密封的趋势。螺杆泵向着大流量和高压力的方向发展。渣浆泵

在19世纪活塞式压缩机几乎成了唯一型式的压缩机。 但由于活塞式压编机存在单机容量小、机器笨重和易损件多等缺点，离心式压缩机和轴流式压缩机才迅速发展起来，1900法国拉托厂首先制造了第一台高炉鼓风用离心式压缩机 ，几年后在欧洲和美国便出现了离心式压缩机的批量生产。离心式压编机的主要优点是单机容量大，重量轻、体积小和结构简单等，为生产大型化提供了条件。随着高压离心式压缩机的有关关键技术的进展，世界许多厂家已能生产出排气压力达( 280~340)x 10Pa或更高的高压离心式压缩机。从进气流量范围看，离心式压缩机在80-6000m3/min的流量范围内得到了广泛应用。

Development of slurry pump and compressor

The concept of centrifugal pump was first proposed by Papin, a French engineer. He invented a machine that can be called the prototype of centrifugal pump in 1689, and made the first pump suitable for lifting liquid in 1750. The pump adopts multi blade impeller and volute pump shell. Euler, a famous French mathematician, made a theoretical analysis on the flow of centrifugal pump in 1750, which laid a foundation for the development of centrifugal pump. In 1818, as a turning point in the history of centrifugal pump development, mass production of centrifugal pump began in the United States. In 1851, jamee stu grwme obtained a patent for invention of multistage centrifugal pump in the UK, and J. tomsom, a British scientist, used guide vanes to improve the efficiency of the pump. In the heyday of steam turbines in the early 20th century, pumps were almost entirely reciprocating. In 1904, KSB company provided a series of high-pressure centrifugal systems for boiler water drawing. In 1905, Sulzer brothers factory started the batch production of multistage series high-pressure pumps.

With the application of mechanical manufacturing technology and computer technology, pumps have been greatly developed in the world. At present, there are more than 5000 kinds of pump products in the world. Pump products have reached a new level in large capacity, high speed, high efficiency, automation and reliability. In the theoretical research of the pump, the computational fluid dynamics method is often used to simulate the actual flow and analyze the flow loss. At the same time, metal materials and non-metal materials have been widely used in the pump industry, effectively improving the pump's ability of corrosion resistance, wear resistance, high and low temperature resistance and impact resistance. Due to the requirements of environmental protection and safety, the reliability of the pump and the requirements of low leakage are also increasing. The common mechanical seal is close to the limit of development, and the magnetic drive pump and magnetic coupling have developed rapidly. At the same time, magnetic fluid seal technology has the trend of replacing magnetic drive pump and double face seal. The screw pump is developing towards the direction of large flow and high pressure. Slurry pump

In the 19th century, the piston compressor became almost the only type of compressor. However, due to the shortcomings of piston compressor, such as small capacity of single machine, bulky machine and many wearing parts, centrifugal compressor and axial-flow compressor have developed rapidly. The first centrifugal compressor for blast furnace blast was manufactured in 1900 lato factory in France. A few years later, the batch production of centrifugal compressor appeared in Europe and the United States. The main advantages of centrifugal press are large capacity, light weight, small volume and simple structure, which provide conditions for large-scale production. With the development of key technologies of high-pressure centrifugal compressor, many manufacturers in the world have been able to produce high-pressure centrifugal compressor with discharge pressure of (280 ~ 340) x 10Pa or higher. From the view of intake flow range, centrifugal compressor has been widely used in the flow range of 80-6000 m3 / min.
