氨泵是强制供液制冷系统中的主要设备之一,泵的选择和安装将决定整个制冷系统的优劣。近年来随着我国冷藏库建设的发展,氨泵的需要量逐年增加,对泵的要求也越来越高。以往的冷藏库多采用齿轮氨泵,由于齿轮泵属正排量泵,其排量与压力无关,而与转速成正比。一般氨泵强制供液制冷系统的特点是要求压力不高而排量较大,当采用齿轮氨泵时,一定尺寸大小的泵,其排量与转速成正比,当排量不变时,泵体越小转速越高,这样带来噪音大与磨损快的缺点。以往采用齿轮氨泵的冷藏库的实践中,辅助间内氨泵的噪音确实很大,
Ammonia pump is a forced liquid supply refrigeration system, one of the major equipment, pump selection and installation will determine the pros and cons of the entire refrigeration system. In recent years, with the development of cold storage in our country, the demand of ammonia pump is increasing year by year, and the requirements of pumps are getting higher and higher. The past cold storage gear pump ammonia, the gear pump is a positive displacement pump, the displacement has nothing to do with the pressure, but with the speed is proportional to. General ammonia pump forced liquid cooling system is characterized by the pressure is not high and large displacement, when the gear ammonia pump, a certain size of the pump, the displacement is proportional to the speed, when the displacement unchanged, the pump The smaller the body the higher the speed, so bring the noise and wear shortcomings. In the past the practice of gear pump ammonia refrigerator, auxiliary ammonia pump noise is really great,
