流体马达,无论是液体抑或气体的,都具有共同的优点——单位重量具有高的转矩和功率,在特殊或有危险性的场合下也能安全操作。然而,气动马达比液压马达具有更优越的性能:具有良好密封的马达长期运转而不会发热,同时,负载一旦减少到适应马达的转矩能力时,气动马达即恢复正常运转;其次,供气管道敷设价廉(管道气压为100～200磅/时~2,即7～14公斤/厘米~2),维修比液压管道要少;再者,从气路连接和轴端密封处的泄出物清洁,而液压泄漏往往会引起压力下降、易燃、损坏装饰表面及弄
Fluid motors, whether liquid or gas, have the same advantages - high torque and power per unit weight and safe operation in special or hazardous situations. However, the air motor has more superior performance than the hydraulic motor: with a good seal of the motor long-term operation without heat, while the load once reduced to adapt to the torque capacity of the motor, the air motor that is back to normal operation; Piping is inexpensive (plumbing pressures are 100-200 lb / h ~ 2, ie, 7-14 kg / cm ~ 2) and maintenance is less than that of hydraulic lines; again, venting from gas connections and shaft seals Clean, and hydraulic leaks often cause pressure drops, flammable, damage to the decorative surface and get
