渣漿泵軸流式壓縮機的出現歷程

軸流式壓縮機的出現則比離心式壓縮機要晚些。 在30年代軸流式壓縮機才得到快速發展。從20世紀40年代開始，軸流式壓縮機已廣泛應用于航空燃氣輪機?，F代軸流式壓縮機效率高達86%~90% ,甚至更高，廣泛應用于發電燃氣輪機船用和機車燃氣透平裝置中。目前軸流式壓縮機在流量為300~ 2500m3 /min排氣壓力為(3~40)x 105 Pa的范圍內得到廣泛應用。

離心式壓縮機在向大型、節能、高可靠性方向發展，技術開發的重點轉向了提高產品的可靠性和運行效率、降低能源消耗、改進生產工藝方法等方面。隨著新技術的發展,三元流動理論被應用到葉輪和擴壓器等流動部件的設計中，以期達到最高的機組效率，設備故障診斷與控制技術、噪聲治理與控制技術將逐步得到使用。由于采用了高效率的三元葉輪及與其匹配的固定元件，壓縮機整機效率已經高達88%以上，而且運轉平穩,檢測、報警及聯鎖停車系統控制水平高，可保證裝置3年以上的運轉周期。近十幾年,干氣密封技術基本取代了浮環密封和傳統的機械密封從而得到廣泛應用。德國MAN公司將磁懸浮軸承、高速電動機和大功率變頻器技術結合形成的整體式壓縮機和電動機結構,取代了干氣密封和傳統的軸承系統，使得離心式壓縮機和驅動電動機的結構更加緊湊,操作也更加方便。渣漿泵廠家
    目前往復式壓縮機的發展方向是:大容量、高壓力、結構緊湊、能耗少、噪聲低、效率高和可靠性高;在產品設計上，應用壓縮機熱力學、動力學計算軟件和壓縮機工作過程模擬軟件等，提高了計算準確度。

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.
