Shanghai Nuoguang produces seven basic models of turbine screw lifts, with lifting capacity, (), maximum input speed and maximum lifting speed. There are different structural types and assembly methods. It is widely used in machinery, metallurgical construction, water conservancy equipment and other industries. The screw lift is a basic lifting component that complies with the / (original /) standard. Carrying capacity, the lift device is self-locking. The screw lift has many functions such as lifting, lowering, pushing with auxiliary parts, turning over and adjusting various height positions.
The lifting principle of the turbine screw lift
It is composed of a worm gear reducer and a lifting screw. Its deceleration component is a worm drive, and the worm is used to drive the worm wheel to achieve deceleration. The center of the worm gear is an internal thread structure, which is equivalent to the nut of the lifting screw and matches the lifting screw. The lifting speed is equal to the worm input speed divided by the reduction ratio of the worm gear, and then multiplied by the pitch of the lifting screw. Due to its structure, this kind of screw lift is generally lubricated with grease. Some series are lubricated with lubricating oil. Compared with the series lubricated with grease, it has the advantages of longer life and stable operation.

Selection instructions
Find out the required lift model based on the screw stroke and lifting load, then check the lifting force and lifting speed tables to check whether the lifting speed meets the requirements.
For example, it is known that the lifting load is the screw rod stroke and the lifting speed. Find the required lift.
According to the screw stroke diagram, select the lift. Then check the lifting force and lifting speed meter to check that the lifting speed is only allowed to be ./ under load, and only reselect a larger model of lift. Then look at the lifting and lifting force speed tables and find out that the allowed lifting speed under load is./ and it meets the requirements
