Electric lifting scraper reducer
The JWZ scraper drive unit adopts single-stage worm gear reduction transmission, which can be powered by a pendulum pinion speed reducer, a variable-speed motor through chain sprockets, V-belt pulleys, or direct coupling. This equipment serves as a low-speed output transmission device, featuring high torque output, low noise, stable operation, and zero leakage. It is primarily used for sludge discharge machinery in water treatment equipment. The speed reducer is available in manual lift, manual-electric dual-purpose lift, and other configurations. Safety shear pins and spring-type overload protection devices (JGZ4500) can be added upon user request to ensure the safe operation of speed coupling equipment.


The specifications of JWZ worm gear reducer for clarification scraper are as follows:

JWZ200JWZ2410JWZ350JWZ420JWZ460 etc.

Choose the appropriate worm gear box according to the size of the clarifier. The following data is for reference only:

Diameter 6 meters: select JWZ200-8-40-ST (DT)

Diameter 8 meters: select JWZ240-10-40-ST(DT)

Diameter 10 meters: select JWZ350-10-60-ST (DT)

Diameter 13 meters: select JWZ420-12-60-ST (DT)

Diameter 6 meters: select JWZ460-10-60-ST (DT)

Each of the above models can be equipped with overload protection device, manual lifting (ST) or electric lifting (DT) according to customer needs.

The first stage reduction motor usually adopts a double-motor cycloid pinwheel reducer, and the appropriate reduction motor is selected according to the different specifications of the worm gear box. The worm gear reducer is connected by a sprocket chain.
