Hand-wheel

Worm Junction box

Fig. 1 Main Parts (sectional view)

The actuator mainly consists of motor, position sensor, worm gear, worm, drive shaft, control unit, local
operation panel, and hand-wheel.
The control units adopt 4~20mA control signal or binary signal to drive the motor, driving the worm which
drives the worm gear and the output shaft. The position sensor will check the motor displacement, and send the
threshold signal to the control panel. If the control panel monitors that the position signal corresponds with the
position specified by control signal, the power supply for the motor will be cut off and the actuator will be stopped
by the worm gear and worm through the self-locking features.
The actuator is an electromechanical product to convert weak signal into torque output in the S4 operation
mode.

2.2 Structure, Function and Operation Principle of Main Parts and Functional Units
2.2.1 Electric control unit
The electric control unit consists of CPU board, dash board, and electric parts. CPU board is used to handle
the given signal and feedback signal. The dash board is used to drive the motor.
2.2.2 Worm gear and worm
This part can slowdown the drive speed of the output shaft of the motor and cause a mechanical self-locking.
2.2.3 Additional gearbox
The additional gearbox is provided for outputting of different torques of the actuator. Relevant information
such as input torque and output torque/force are recorded in the data marks on the additional gearbox.

2.3 Functional Structure, Operation Principle, and Operation Features of the Structural Units
The external control signal is applied to the electric control unit through the cable of junction box. Electric
control unit uses photoelectric isolation and transformer isolation to drive the motor, and then drive the worm gear
and worm, and the output shaft, which is the feature of weak current controlling strong current.

2.4 Functional Structure, Operation Principle and Features of Auxiliary Device

Hand wheel: it is used for installation and commissioning, troubles shooting with manual and electric switch.
If the hand wheel is impelled to the worm axis, and the control power cuts off the electric mode, manual operation
can be done safely; if the force is not applied to the hand wheel, it can be reverted to the electric mode
automatically.

7. Maintenance and Repair
Actuator should undergo the following check items every year to ensure the operation without errors and
necessary safety measures should be taken before the check, maintenance of the actuator to ensure the smooth and
safe maintenance process.
During the check and maintenance, power supply to the main circuit and sub circuits should be cut off and
some charged parts around should be isolated.

7.1 Routine Maintenance and Calibration

1. Appearance visual check;
2. Regularly clean the actuator in case that the actuator is damaged as a result of local overheating caused
by accumulated dust on the exterior surface;
3. Canopy should be put up to protect equipments against rain in the open area.
4. Examine regularly and make examination records.

7.2 Runtime Maintenance

1. Check the tightness of fasteners (including screws);
2. Lubricate the connection part of the output torsion periodically;
3. Check whether the operation record meets the technical requirements and whether there is anything
abnormal;
4. Check for oil leakage;
5. Check the connection of the power cord and signal wire.
7.3 Examination Period
Generally, it is not necessary to carry out maintenance for the actuator (except the regular lubrication for the
connection of output torsion) and a routine inspection every 3 months is necessary to check:
1. Whether specified technical parameters are met;
2. Whether the actuator works normally (vibration, noise etc.)
3. Whether there is any oil leakage;
Overhaul of the actuator should be carried out during the lubricant replacement and by the organizations
armed with certain examination abilities.

7.4 Reduction Gearbox

It is suggested that gasket ring and oil of reduction gearbox be replaced in the following period.
They should be replaced every 5 years when the average ambient temperature is no more than 40°C and
replaced every 2 years when the average ambient temperature is no more than 60°C.

7.5 Motor
Bearings and gasket rings of the shaft should be replaced in the following period due to high temperature and
mechanical load during the phase conversion of the motor:
They should be replaced every 3 years when the average ambient temperature is no more than 40°C and
replaced every 2 years when the average ambient temperature is no more than 60°C.
Maintenance in every other year is needed if the motor always bears load when reaching the end position.
