中国科学院广州能源研究所委托我所研制的微型溴化锂屏蔽泵(配带电机为0.75kW)应用于小型溴化锂吸收式制冷机试验装置。该装置是一种利用余热为动力的节能产品,广泛用于大型宾馆和小型工矿企业。微型溴化锂屏蔽泵的研制成功将为节约能源、提高经济效益开辟新的途径。由于该泵的参数特殊,比转数低(1XPB-2型泵n_з=24.4,1XPB-3型泵n_з=34.3),流量小,汽蚀性能要求高,吸入真空度需要8～9米,是一种要求严、研究难度大的泵,国内无现成产品,甚至连这方面的参考资料也难找到。为了开发离心泵的使用领域,从而进行了该泵的研制。
Guangzhou Institute of Energy Chinese Academy of Sciences commissioned by our development of miniature lithium bromide shielding pump (with motor 0.75kW) used in small lithium bromide absorption chiller test device. The device is a kind of energy-saving products using waste heat as power, widely used in large hotels and small industrial and mining enterprises. The successful development of miniature lithium bromide shielding pump will open up new avenues for saving energy and improving economic efficiency. Due to the special parameters of the pump, the specific rotation speed is low (1XPB-2 pump n_з = 24.4, 1XPB-3 pump n_з = 34.3), small flow, high cavitation performance requirements, vacuum suction requires 8 to 9 meters, A rigorous research, difficult to study the pump, the domestic substandard products, and even references in this area is hard to find. In order to develop the use of centrifugal pumps, thus the development of the pump.
