【摘要】：随着社会环保意识的不断增强,人们对机械产品的易用性、安全性要求正在不断提高,因此传统的往复式活塞压缩机正在迅速地被滑片式空气压缩机取代。滑片式空气压缩机具有成本低可靠性高节能、环保、使用寿命长等特点,本文以滑片式空气压缩机为研究对象,作为一种动力设备,它广泛应用于汽车钢铁制药食品等工业中,并且正在发挥着举足轻重的作用。本文主要对滑片式空气压缩机油气流程进行了分析,对压缩机的滑片定子进行了深入的模拟仿真。首先在油气流程分析的基础上对其润滑油的作用进行了研究,提出了其润滑油的选取原则和质量指标,然后对喷油润滑进行了研究,重点分析了喷油量、喷油压力及喷油位置。接着对滑片式空气压缩机的滑片进行动力学分析,研究滑片的参数对压缩机的性能的影响,同时对滑片速度、加速度进行运动分析,通过分析计算出压缩机的摩擦功率变化规矩,对滑片进行受力分析,然后对滑片进行受力模拟,分析其变化规律,最后对滑片式空气压缩机的定子进行有限元分析,观察定子在工作过程中受到的应力是否在允许的范围内。这几个方面因素直接影响着滑片式空气压缩机的可靠性及运行效率。如果能够合理选择设计这些参数可以有效的降低摩擦损失,对于滑片式空气压缩机机械效率的性能改善和提高具有一定意义,为产品的设计和优化提供了有益的参考
[Abstract]:With the increasing awareness of environmental protection, people are improving the safety and ease of use of mechanical products, so the traditional reciprocating piston compressor is rapidly replaced by sliding air compressor. Sliding Vane Air Compressor with low cost? High reliability? Energy saving, environmental protection, long service life and other characteristics, this paper takes the slider type air compressor as the research object, as a kind of power equipment, it is widely used in automobile? steel Pharmacy? Food and other industries, and are playing a pivotal role. In this paper, the oil and gas flow of the slider air compressor is analyzed, and the slider of the compressor is analyzed. The stator is simulated deeply. Firstly, based on the analysis of oil and gas flow, the function of lubricating oil is studied, and the selection principle and quality index of lubricating oil are put forward. Then, the lubrication of injection oil is studied, and the injection quantity, injection pressure and injection position are analyzed emphatically. Then the dynamic analysis of the slider type air compressor is carried out, and the influence of the parameters of the slider on the performance of the compressor is studied. At the same time, the velocity and acceleration of the slider are analyzed. Through the analysis and calculation of the friction power variation rules of the compressor, the force of the slider is analyzed, and then the force of the slider is simulated, and the law of variation is analyzed. Finally, the finite element analysis of the stator of the slider type air compressor is carried out. Observe whether the stress of the stator in the course of work is within the allowable range. These factors directly affect the reliability and operation efficiency of slider air compressor. If these parameters can be reasonably selected, friction loss can be reduced effectively, which is of significance to the improvement of mechanical efficiency of slider air compressor and provides a useful reference for the design and optimization of products.
