Direct-Connected Screw Actuator is powered by an electric motor to drive the worm and worm gear, offering high power and a simple structure, easy to maintain.

The two-in-one hand torch screw jack is driven by an electric motor connected to a belt pulley, which then powers the worm gear through a V-belt.

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. 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 adjusting water level and flow rate.

2. Structural Features

(1) The key component of this machine, the worm gear, differs from traditional products by being cast from tin-phosphorus bronze (ZCuSn10P1). The worm gear teeth are treated with high-frequency quenching and machined on a special milling machine, offering excellent wear resistance and significantly extended 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 height. It also allows setting of opening and closing heights, as well as upper and lower limits. For automatic control of pump stations, an electronic altimeter can be configured for both 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 bidirectional overload automatic protection for door opening and closing. The device allows interlocking of flashlights and features waterproofing capabilities.

(4) This machine boasts compact size, light weight, attractive design, rapid speed increase, and features like direct motor and worm gear connection without slippage, making it suitable for both indoor and outdoor applications.
