柱塞副磨损状态下的轴向柱塞泵泄流口温升特性
Temperature Rise Characteristics of Axial Piston Pump Drain Port Under Wear Condition of Piston Pairs
摘要
Abstract
The wear of the piston pairs in the axial piston pump causes changes in the temperature of the drain port,and the research on the law of change is carried out.This study established an AMESim simulation model of axial piston pump with 9 pistons,and built a piston experimental platform for verification.The results show that under the condition of 1000 r/min speed and full displacement,when comparing the temperature differences between the drain port and the inlet port of the piston pump,the temperature difference of the piston pump with one piston pair suffering from severe wear is about 6℃higher than that of the normal piston pump.However,there is no significant difference in the temperature of the pump case.The simulation model shows that the oil temperature at the drain of the pump increases with the increase of the rotational speed of the piston pump,and the temperature of the drain port increases with the increase of the clearance of the piston pair.The research indicates a positive correlation between the wear clearance of the piston pair of the axial piston pump and the temperature difference between the pump's drain port and inlet port,and it provides a basis for predicting the wear of the piston pair based on the temperature difference between the drain port and the inlet port.关键词
