一、概述活塞式气动马达是容积式气动马达的一种,它与其他容积式气动马达(如叶片式、齿轮式等)相比较有下述优点:由于活塞式气动马达密封性好,泄漏量相对减少,绝热总效率较高;还由于活塞式气动马达转速较低,运转中噪声也较低些。但是活塞式气动马达的体积与重量显得大些。如果使用中对气动马达的体积与重量无特殊要求时,一般乐于选用活塞式气动马达。目前活塞式气动马达大多是各个气缸在机体上径向而均匀排列,运转时既可正转,也可反转,且正反转性能完全相同,故有正反转性能相向径向活塞式气动马达或双向径向活塞式气动马达的名称。活塞式气动马达的缺点之一是重量较大,因而在满足性能的前
I. Overview Piston air motor is a positive displacement air motor, which with other positive displacement air motor (such as vane, gear, etc.) compared to the following advantages: As the piston air motor sealing, leakage Relatively reduced, the overall efficiency of the adiabatic higher; also due to lower piston air motor speed, noise in operation is also lower. But the piston air motor size and weight appear larger. If the use of the volume and weight of the air motor no special requirements, the general willing to use piston air motor. At present, most of the piston air motors are arranged radially and uniformly on the airframe, and they can rotate either forward or reversely with the same positive and negative reversing performance. Therefore, the reciprocating performance of the reciprocating radial air pistons Motor or bi-directional radial piston air motor name. One of the drawbacks of piston air motors is their heavier weight, thus meeting the performance requirements
