Working principle of worm screw lift

The turbine screw lift is a mechanical device that converts the rotation of the motor into the linear motion of the screw through the turbine drive double screw lift motor, thus realizing the lifting. Its working principle is as follows: --The motor is connected to the turbine through the coupling and converts the power into power to drive the turbine to rotate. --The rotation of the turbine drives the rotation of two spiral wheels, each with a lead screw. --The lead screw rotates with the rotation of the wheel. Through the engagement with the nut, the nut plate moves linearly along the lead screw. --The nut plate is connected to the lifting table, so the lifting table moves linearly with the nut plate, thus realizing the lifting of the turbine screw lift. Summary: The turbine lead screw elevator drives the turbine to rotate through the motor, and then drives two spiral wheels to rotate, driving the lead screw to rotate. With the engagement with the nut wheel, the lifting table can rise and fall.

Turbine screw lift can be applied to many different industries and occasions, and is an effective way to carry out material transportation, equipment maintenance and cargo handling. The main application fields are listed below: Warehousing and logistics: The turbine screw elevator can transport the warehouse goods from the ground to the truck, or transport the goods from the truck/container to the warehouse. Industrial manufacturing: heavy industrial equipment and machinery can be lifted and adjusted from the ground to facilitate maintenance and repair. In addition, it can also be used for material handling in factories or process workshops. Commercial and retail: Supermarkets, shopping malls and other sales places can use turbine screw elevators to move goods to different floors, or move goods from/to vehicles. Health care: The turbine screw lift can be used in hospitals, clinics, research and development centers and other places to help improve efficiency and health quality. In short, the turbine lead screw elevator is widely used, involving many different industries and occasions, mainly in various object handling and transportation occasions. It has the advantages of heavy-load beam erection, high efficiency and space saving, which helps to improve staff efficiency, reduce work intensity and promote production efficiency.

Production process of turbine screw elevator

Design: according to the user's needs and requirements, design a special turbine screw lift scheme, including the design of turbine, screw, nut, support structure, control system, etc. Material preparation: according to the design requirements, prepare corresponding materials, such as turbine, screw rod, nut, platform, etc., and the materials shall comply with relevant national standards and requirements. Turbine manufacturing: generally, turbine materials are made of high-quality cast iron, steel and other specially processed materials, which are processed and shaped by CNC processing equipment. Manufacturing screw rod and nut: according to the design requirements, the screw rod and nut shall be manufactured, and the surface polishing and heat treatment shall be carried out. Platform processing and manufacturing: according to the design drawings, select the corresponding materials and shapes, and carry out shearing, welding, polishing and other processes. System assembly: assemble the manufactured turbine, screw rod, nut, platform and other components, and install the control system for testing and quality inspection. Commissioning and acceptance: The equipment shall be commissioned and accepted by professional personnel to ensure that the equipment meets the design requirements and meets the safety and quality standards. Delivery and installation: packaging and logistics delivery shall be carried out for the accepted equipment, and installation and commissioning shall be carried out at the customer's site to ensure the normal operation of the turbine screw lift. In short, design, material preparation, manufacturing and assembly are all crucial to the production process of the turbine screw lift. Any problem in any link will seriously affect the performance and quality of the turbine screw lift produced.
