Direct-acting screw actuators are driven by the motor directly rotating the worm and worm gear, offering high power, simple structure, and easy maintenance.
The two-in-one screw jack for flashlights is driven by an electric motor connecting a belt pulley, which in turn drives the triangle belt. The triangle belt then connects to a worm gear, causing it to rotate.
Operating Principle
The QL type direct-connected screw actuator consists of a worm, worm gear, screw, nut, thrust bearing, matching motor, and hand crank. When the power (or hand crank) drives the worm to rotate, the worm gear and nut also rotate accordingly. The rotation of the worm gear and nut forces the screw to move up and down, thereby controlling the gate's opening and closing and regulating water level and flow rate.
2. Structural Features
The key component, the worm gear of this machine, differs from traditional products by being cast in tin phosphorus bronze (ZcuSn10P1). The worm gear teeth are treated with high-frequency quenching and precision machined on a special grinding machine, offering excellent wear resistance and significantly extending the service life.
(2) The machine boasts excellent self-locking performance and a simple structure. It can be adjusted using a mechanical altimeter, allowing the gate to remain at any desired height. It also allows setting of opening and closing heights, as well as upper and lower limits. During automatic control of the pump station, an electronic altimeter can be configured for local and centralized control.
(3) Equipped with electrical protection devices, stroke limit switches, and dual-purpose electrical interlock devices for flashlight use, this system provides automatic overload protection for both opening and closing doors. The device allows for interlocking of flashlights and features waterproofing capabilities.
(4) This machine boasts compact size, light weight, attractive design, quick speed increase, and features such as direct connection between the motor and worm without slipping, making it suitable for both indoor and outdoor applications.
