1.当重庆升降机负载不变时，节流阀口进越小，则系统速度刚度进越高；反之，若节流阀开口面积越大，则进越低。When the Chongqing lift load unchanged, the throttle orifice into the smaller, the system speed stiffness into the higher; on the contrary, if the throttle valve opening area, the lower the.
2.当重庆升降机负载不变时，低速下的速度刚度好，当负载变化时，负载小时的速度刚度好。When the Chongqing elevator load is constant, the speed of the low speed is good. When the load changes, the speed of the load hour is good.
3.提高重庆升降机供油压力加大液压缸有效作用面积，可提高速度刚度。Increasing the effective area of the hydraulic cylinder for increasing the supply pressure of the Chongqing lift can increase the speed of the hydraulic cylinder.
