渣浆泵轴流式压缩机的出现历程

轴流式压缩机的出现则比离心式压缩机要晚些。 在30年代轴流式压缩机才得到快速发展。从20世纪40年代开始，轴流式压缩机已广泛应用于航空燃气轮机。现代轴流式压缩机效率高达86%~90% ,甚至更高，广泛应用于发电燃气轮机船用和机车燃气透平装置中。目前轴流式压缩机在流量为300~ 2500m3 /min排气压力为(3~40)x 105 Pa的范围内得到广泛应用。

离心式压缩机在向大型、节能、高可靠性方向发展，技术开发的重点转向了提高产品的可靠性和运行效率、降低能源消耗、改进生产工艺方法等方面。随着新技术的发展,三元流动理论被应用到叶轮和扩压器等流动部件的设计中，以期达到最高的机组效率，设备故障诊断与控制技术、噪声治理与控制技术将逐步得到使用。由于采用了高效率的三元叶轮及与其匹配的固定元件，压缩机整机效率已经高达88%以上，而且运转平稳,检测、报警及联锁停车系统控制水平高，可保证装置3年以上的运转周期。近十几年,干气密封技术基本取代了浮环密封和传统的机械密封从而得到广泛应用。德国MAN公司将磁悬浮轴承、高速电动机和大功率变频器技术结合形成的整体式压缩机和电动机结构,取代了干气密封和传统的轴承系统，使得离心式压缩机和驱动电动机的结构更加紧凑,操作也更加方便。渣浆泵厂家

The history of axial compressor of slurry pump

Axial compressor appears later than centrifugal compressor. In the 1930s, axial compressors developed rapidly. Since 1940s, axial compressor has been widely used in aviation gas turbine. The efficiency of modern axial compressor is up to 86% ~ 90%, even higher. It is widely used in marine and locomotive gas turbine. At present, axial-flow compressor is widely used in the range of discharge pressure (3 ~ 40) x 105 PA with flow of 300 ~ 2500m3 / min.

Centrifugal compressor is developing towards large-scale, energy-saving and high reliability. The focus of technology development has shifted to improving the reliability and operation efficiency of products, reducing energy consumption and improving production process. With the development of new technology, three-dimensional flow theory is applied to the design of flow components such as impellers and diffusers in order to achieve the highest unit efficiency. Equipment fault diagnosis and control technology, noise control and control technology will be gradually used. Due to the use of high-efficiency three-dimensional impeller and its matching fixed elements, the overall efficiency of the compressor has reached more than 88%, and the operation is stable, and the control level of detection, alarm and interlocking shutdown system is high, which can ensure the operation cycle of the device for more than 3 years. In recent ten years, dry gas seal technology has been widely used instead of floating ring seal and traditional mechanical seal. Man company of Germany combines magnetic bearing, high-speed motor and high-power inverter technology to form integral compressor and motor structure, replacing dry gas seal and traditional bearing system, which makes the structure of centrifugal compressor and driving motor more compact and operation more convenient.

At present, the development direction of reciprocating compressor is: large capacity, high pressure, compact structure, less energy consumption, low noise, high efficiency and high reliability; in product design, the application of compressor thermodynamics, dynamics calculation software and compressor working process simulation software improves the calculation accuracy.
