摘要
通过开展正交试验,分析空调冷却水泵机械密封参数优化问题。经方差分析观察到,在机械密封端面摩擦功耗方面,不同工艺参数对密封端面摩擦功耗均会产生一定的影响,其中,电机转速对密封端面摩擦功耗所产生的影响最大,其次为介质压力,弹簧比压则对密封端面摩擦功耗影响相对较小。分析极差分析结果可以发现,随着弹簧比压和电机转速以及介质压力的不断增加,密封端面摩擦功耗也会随之呈现出不断增大的变化趋势。经过机械密封泄漏量方差分析,对密封端面摩擦功耗产生较大影响的工艺参数为弹簧比压,其次为介质压力,电机转速对密封端面摩擦功耗所产生的影响则相对较少,另外,弹簧比压会对泄漏量产生较大的影响。最终分析确定机械密封的最佳工艺参数条件为:弹介质压力为0.60 MPa,电机转速为2960 r/min,簧比压为0.06 MPa。
In the research process of this article,orthogonal experiments were conducted to analyze the optimization of mechanical sealing parameters for air conditioning cooling water pumps.Through analysis of variance,it was observed that different process parameters have a certain impact on the friction power consumption of mechanical seal end faces.Among them,the motor speed has the greatest impact on the friction power consumption of seal end faces,followed by the medium pressure,and the spring specific pressure has a relatively small impact on the friction power consumption of seal end faces.Analyzing the range analysis results,it can be found that with the continuous increase of spring specific pressure,motor speed,and medium pressure,the friction power consumption of the sealing end face will also show a continuous increasing trend.After variance analysis of mechanical seal leakage,different process parameters will have a certain impact on the friction power consumption of the sealing end face.The process parameter that has a significant impact on the friction power consumption of the sealing end face is the spring specific pressure,followed by the medium pressure.The motor speed has a relatively small impact on the friction power consumption of the sealing end face.In addition,the specific pressure of the spring will have a significant impact on the leakage rate.The final analysis determines the optimal process parameters for mechanical seals as follows:the pressure of the elastic medium is 0.60 MPa,the motor speed is 2960 r/min,and the spring specific pressure is 0.06 MPa.
