Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] Such as figure 1 , 2 As shown, the centrifugal compressor cooling water intelligent adjustment system includes a primary cooler 9 and a secondary cooler 10. The primary cooler is connected to the main water inlet pipe 8 through the primary water inlet pipe 11, and connected to the main The water outlet pipe 7 and the secondary cooler 10 are connected to the main water inlet pipe 8 through the secondary water inlet pipe 14, and are connected to the main water outlet pipe 7 through the secondary water outlet pipe 13. Temperature sensing devices are installed at 1 exhaust port of the primary cooler, 2 exhaust ports of the secondary cooler, and 7 main water inlet pipes, and a primary sensor is installed at the point where the primary cooler is connected to the primary water outlet pipe. The electric regulating valve 6 is provided...

The invention relates to a centrifugal type compressor cooling water intelligent regulating system. The system comprises a primary cooler and a secondary cooler; temperature sensors are arranged respectively at the position of an air exhaust opening of the primary cooler, at the position of an air exhaust opening of the secondary cooler, and at the position of an overall water inlet pipe; a primary electric regulating valve is arranged at the connecting joint between the primary cooler and a primary water outlet pipe; a secondary electric regulating valve is arranged at the connecting joint between the secondary cooler and a secondary water outlet pipe; and water inlet amount is regulated by regulating the openness of the primary electric regulating valve and the secondary electric regulating valve. According to the system, through real-time monitoring of temperature and pressure of the primary cooler and the secondary cooler, openness of the electric regulating valves for water inletof the coolers is adjusted in real time, so cooling water supply amount is regulated, optimal cooling is realized, optimal working condition is achieved and energy saving and consumption reduction ofa centrifugal type compressor are realized. Through intelligent distribution and regulation of cooling water, high-efficiency and energy-saving operation of a unit is realized.
Description
technical field [0001] The invention relates to a centrifugal air compressor. Background technique [0002] The centrifugal compressor adopts the working method of multi-stage compression and inter-stage cooling, and the compressed outlet air of each stage is cooled by a water-cooled heat exchanger before entering the next stage for compression. The performance of the coolers at each stage directly affects the compression efficiency of the next stage and the power consumption of the unit. Taking the three-stage centrifugal compressor unit as an example, the cooling water first flows through the water inlet pipe of the main pipe, and then is distributed to the first-stage intercooler, the second-stage intercooler, the aftercooler, and the lubricating oil cooler. After the cooling is completed, it is collected again in the water outlet pipe of the main pipe and discharged out of the compressor system. When the cooling water is distributed unevenly, some coolers will be overc...
