First consider the load on the screw lift. The choice of the lift is that the static load, the dynamic load, and the impact load cannot exceed the large load that it is allowed to bear. The lift with sufficient capacity should be selected according to the safety factor, the travel stroke, and the stability of the proof screw.
Determine the speed ratio of the lift. The speed ratio of the screw lift is generally divided into normal and slow speed, which needs to be determined according to the actual use.
Determine how the screw lift is connected to the motor. Connections are flanged and biaxial. The head type of the screw lift is cylindrical, flanged, threaded and flat.
Secondly, pay attention to the use conditions and running time of the lift. When the elevator is running, the surface temperature should be controlled within the range of -15°~80. When the ambient temperature is lower than zero degrees Celsius, the efficiency of the whole machine will decrease due to the viscosity change of the lubricating oil. Therefore, a sufficient driving source should be selected.
The use frequency and efficiency of the common screw lift and the ball screw lift are very different. The ball screw of the ball screw lift adopts Taiwan ABBA.
