QDA18t sewage treatment plant electrical installation | electric head type hoist

QDA sewage treatment plant electrical installation | electric head type hoist:

Electric screw hoists are widely used in various drainage, water conservancy, and hydropower projects to control the lifting and lowering of gates, barriers, and valves, thereby achieving the opening and closing of gates, barriers, and valves

The main features of QDA electric screw opening and closing machine are:

Features include comprehensive functionality, reliable performance, control system *, small size, light weight, and easy use and maintenance.
It has features such as overload shutdown protection, accident alarm display, and upper and lower travel limit control.
Equipped with a manual and electric switching mechanism, it automatically disconnects the power supply.
Both integrated switch type and integrated regulation type can achieve on-site and remote control functions.
Outdoor and explosion-proof protection level: IP55 (special order IP65, IP67)
Instantaneous torque protection: When the opening or closing torque is instantly pushed open, the gate will stop and not move. Even if the torque switch is instantly pushed open and closed, the gate will not move. Only one reverse motion can release the over torque protection.
Phase loss protection: It has the function of power phase loss and output phase loss protection.
