SWL screw liftWhen selecting the model, it is necessary to pay attention to the adjustment of the speed of the screw shaft and the accepted load, and to verify the allowable load, allowable external load, and allowable rotation speed of the screw shaft of the screw lift. Serious damage to the entire lifting device.No matter the static load, dynamic load or impact load of the screw lift, it cannot exceed its allowable load. It is necessary to choose a lift with sufficient capacity according to the safety factor, the operating stroke, and the stability of the correction screw.When the elevator is operating, the surface temperature of the deceleration part should be controlled within the range of -15°C to 80°C, and the surface temperature of the movable nut should also be within this range.
In the purchaseSWL screw liftWhen considering the load of the screw lift.The choice of the elevator is that no matter the static load, dynamic load or impact load can not exceed the allowable load, the elevator with sufficient capacity should be selected according to the safety factor, the use stroke, and the stability of the proofing screw.Determine the speed ratio of the elevator.The speed ratio of the screw lift is generally divided into ordinary and slow speed. This needs to be calculated and determined according to the actual use situation, and the connection method of the screw lift and the motor is determined.The connection methods include flange direct connection and double shaft type.The head types of screw lifts are cylindrical, flanged, threaded and flat head.Also pay attention to the conditions of use and operating hours 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 influence of the viscosity of the lubricating oil, so a sufficient driving source should be selected.
