1.當重慶升降機負載不變時，節流閥口進越小，則系統速度剛度進越高；反之，若節流閥開口面積越大，則進越低。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.當重慶升降機負載不變時，低速下的速度剛度好，當負載變化時，負載小時的速度剛度好。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.提高重慶升降機供油壓力加大液壓缸有效作用面積，可提高速度剛度。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.
