一、前言本文分析了叶片式真空泵运转时,它的驱动力矩、困油油压力矩、(指从排气终角到顶隙的压缩负力矩——译者注)、大气从排气口流入造成的空气压差力矩、输送空气需要的力矩以及摩擦力矩之间的关系。如果恰当地选择泵的进、排气角度,则油压及空气压差力矩等可以减少,结果使得摩擦力矩占去了整个驱动力矩的绝大部份。近几年来,讨论各种油压泵及马达和空气压缩机等力矩特性的文献很多,特别是以摩擦力矩为中心议题进行了很多研 I. INTRODUCTION This paper analyzes the driving torque and oil pressure moment when the vane vacuum pump is in operation. The atmospheric pressure inflows from the exhaust port The pressure difference between the air pressure, the delivery of air required torque and the relationship between the friction torque. If you choose the right pump intake and exhaust angle, the hydraulic pressure and air pressure torque can be reduced, the result makes the friction torque accounted for most of the entire driving torque. In recent years, many kinds of torque characteristics such as various hydraulic pumps and motors and air compressors are discussed. In particular, many studies have been carried out on the friction torque as the central issue
