电动、液压和气压是传动装置中三种主要的运动技术。你使用哪一种要取决于应用的特点。电动控制,在需要移动非常准确或者需要连续移动的时候,是非常出色的。电动伺服控制在多种应用中有用处:比如机器中心或者电梯内部对轴的计算机数字控制(CNC)。这种控制经常出现在装配操作中。液压,当需要快速反应的时候,是大负载条件下的选择。它可以承受的压力是三个运动类型中最大的,最多可以达到100吨。气压,在不利的环境中可以保证安全和可靠性,它对于高温、低温、灰尘、机械振动、潮湿以及电子噪音都不太敏感。 Electric, hydraulic and air pressure are the three major sports technologies in the transmission. Which one you use depends on the characteristics of the application. Electric control is excellent when you need to move very accurately or need to move continuously. Electric servo control is useful in a variety of applications such as computerized numerical control (CNC) of the axes inside a machine center or elevator. This control often occurs during assembly operations. Hydraulic, when the need for rapid response time, is under heavy load conditions of choice. The pressure it can withstand is the largest of the three movement types, up to 100 tons. Air pressure, which guarantees safety and reliability under unfavorable conditions, is less sensitive to heat, cold, dust, mechanical vibrations, humidity and electrical noise.
