1. Housing: hard-anodized AL alloy and external
coating of epoxy powder is suitable for the
severe condition especially against the
corrosion. Housing is designed in accordance
with standard of Explosion-proof and IP67.
and
also we can off HAITIMA
TM HTQ with
IP68 for option.
2. Motor: specially designed with squirrel
caged
induction motor to generate high
starting
torque and high efficiency equipped
with
over heating. it has several features
such as
high output power, high efficiency and
lower
noise. |
 |
|
|
3. PCU: high performance microprocessor,
auto-calibration
provides the most convenient
to user without complicated set in
field.
4. Sealing: sealing provided by double O-ring system.
|
 |
| |
|
5. Handwheel: Just by pulling over the lever, operating mode is
switched to manual. then just supplying electrical power to
actuator, clutch is automatically disengaged from manual and
operating mode is switched to electric operation. The size of
hand wheel is designed according to required torque to move
the actuator, so that operator can easily move the actuator by
hand. |
 |
| |
|
6. Gear & self locking: 2nd staged double worm gearing prevents
movment caused by backward force transferred from valve and
it provides the exact and stable position of actuator and valve
when the power is off. High efficiency, high output torque, low
noise level are another advantages. |
 |
| |
|
7. Limit switches: directly engaged with driving
shaft to set accurate position of valve.
Torque swithces: to protect actuator from dama ge caused by over
torque from the
driven valve over the whole
travel. |
| |
8. Anti-condensation space heater: the switch is
open when the temperature is around
20+3 °C
to protedct actuator condensation; The switch is close when the
temperature
is over 30+3 °C
to prevent over heating. |
9. Stopper bolt: stopper bolt installed both close and
open direction prevents actuator's travel the limit
during manual operation and also protects internal
gearing from its breakaway. |
 |
10. Indicator: through the large size indicator window
provides better position indication form a distance. |
|
11. Terminal block: it is easy to add the number of strip
for additional connection, spring loaded terminal
strip is very strong against vibration. |
 |
| 12. Wiring: the inside wiring is so simple and easy to connect. |
|
| |
|
13. Driving bushing: the driving bushing is removable
to process, mounting base is designed according
to ISO5211, it is convenient to adapt with valve.
14.
Lubrication: all the gears and shafts use
CIATM221 type Grease Moly, it is not necessary to
refill lubricant for 5 years. |
 |
| |
|
15. Anti-interference magnetic loop: it effectively
prevents the actuator from outside magnetic field,
and keeps the actuator operating stable. |

HAITIMA
TM HTQ electric actuator guaranty high
performance and stable
quality product throughout severe test and
inspection. We can provide
advanced intelligent model with
different models for option. |
| |
|
1. Using very large scale digital integrated chip,
so it has very powerful function and high
accuracy. Once the actuator is supplied power, it wil auto-check the
control circuit to
insure the correct
operation. |
| |
|
2. Displacement transducer of actuator is n. hall
sensor with digital quantization impulse
signal, Hall magnetically pulse effects system can measure and
control the travel of
actuator exactly. |
| |
|
3. Using IA infrared ray
system, IA always supports
communication compatible with IrDA. The
function
specification of actuator can be set,
adjusted and operated by
handheld infrared
remote controller, it is not necessary to open
the top cover to reveal the inner control circuit. |
 |
| |
|
4. Using liquid crystal display with high-resolution, English
mark
to indicate the travel percent of valve,
It is very convenient to
use in the night. LED
signal with high lightness to indicate the
position of actuator: full open-Red, full close-Green.
The
backup batteries will support the LED
display when the main
power is off. |
 |
| |
|
5. The remote and local control (open/close/stop) function, with
local lamp indication: full close-Green (on). Closing-Green
(flickering). Torque switch trip-Yellow (on),
Fault-Yellow
(Flickering). Full
open-Red(on), Opening-Red(Flickering).
Reversing, electronic contactors, Transformer, Phase
discriminator has detection and auto-correction. 24 to 48
points terminal strips on terminal block for option. Position
monitoring relays with remote position indication, local digital
position indication. |
