- 摘要:
- 为满足API 610标准要求,遵循成本最小化原则,对原有小功率卧式高速泵的增速箱及电机端盖按照组合设计开发了新的增速箱。改进设计中,最大限度采用原有增速箱及相关零部件,并将新的低速轴承由原来的脂润滑改为油浴润滑。改进后整机外形尺寸、重量及成本的增幅都控制在10%可接受的范围内。经过试验,改进设计后该泵型各项机械性能指标良好,低速轴承温度较之前有了明显的降低,加装联轴器后整泵机组的振动速度与振动位移也大幅减小,符合新标准的要求,提高了该泵型的维护便利性和适用范围。
- Abstract:
- To meet API 610 standard and abide by the principle of cost minimum, the gearbox of the original horizontal miniwatt high-speed pump and motor side cover were improved according to the combinational design idea. In the improvement design, the original gearbox and relevant parts were used as possible, and the grease lubrication was replaced with oil bath lubrication for the low speed bearings. The size, weight and cost of the improved pump are increased, but the increased amplitude is controlled within 10%. The test results prove that each performance index of the improved pump is excellent, and the temperature of low-speed bearings and the vibration of the pump are much lower than the original one. It accords with the newest standard. Its maintenance convenience was improved and its application range was expanded.
