摘要:
大型泵站电机滑动轴承发热量大，需要冷却水系统冷却，控制轴瓦温度不致烧熔损坏影响泵机组安全运行。为了既要保证轴承运行温度得到控制，又要减少冷却水系统能耗，以大型泵站主电机为对象，计算滑动推力轴承发热量，对轴承-润滑油-油冷却器-冷却水系统进行冷却传热计算，计算预测了间接供水系统不同主机运行台数时的轴瓦运行温度及其规律，提出了冷却水系统的变阀优化运行方案。结果表明，实例泵站冷却水系统恰好能够满足全泵站机组最不利工况下，电机轴承运行温度的控制要求；冷却水进水温度越高，泵站主机开机台数越多，推力轴承瓦温越高；冷却
Abstract:
A cooling water system is required for cooling motor sliding bearings of large pump station for large amount of friction heat to control the bearing bush temperature so as not to cause burning damage and affect safe and reliable operation of the pump unit. In order to not only ensure the operating temperature of the bearing is controlled, but also reduce the energy consumption of the cooling water system, the main motor of the large pumping station is used as the object to calculate the calorific value of the sliding thrust bearing and the cooling heat transfer of bearing-lubricating oil-oil cooler-cooling water system. The operating temperature and law of the bearing bushes in the indirect water supply system with different numbers of main engines are calculated and predicted, and the optimal operation scheme of the variable valve of the cooling water system is proposed. The results show that the cooling water system of the example pumping station can just meet the control requirements of the motor bearing operating temperature under the most unfavorable working conditions of the whole pumping station unit; the higher the inlet temperature of the cooling water, the more the main engine of the pump station is turned on, and the higher the temperature of the thrust bearing pad. The optimized operation of the cooling water system has a significant energy saving effect, which can provide a reference for the design and operation management of the cooling water system for large motors.
