Coil spring loaded slotted oil control ring
This text summarises several control forms of gushing out oil pump test platform simply, and mainly proposes analog and digital control schemes of close ring adjusting speed, at the same time, gives the principles and implementation methods used in parameters control and measuring, this text introduces the asynchronous electromotor " s control process, in which, fuzzy control arithmetic is used, and the control commands are passed on by means of communication between mcu and frequency converter. there are two parts in this system. one is superior computer that is ordinary pc, the other is hypogynous at89c52. the functions of superior pc are control and display information through screen, and the functions of ats9c52 includes control, collecting, display, treatment, uploading of all parameters
1. 5 m in diameter ) were dispersed in n46 engine oil with different concentrations using ultrasonic respectively in order to study their tribological properties. the tribological experiments were carried out by mq - 800 four - ball tribometer and mm - 200 ring - on - block tribometer, in which extreme pressure properties, wear scan diameter, friction coefficient and wear volume loss were measured. the results showed that oil containing mos2 nanoparticles had a better wear resistance, friction - reducing and extreme pressure than the oil containing common mos2
