The fearture are as below:
1. Advanced design
The HK Series Electric actuators offers many specially
performances, high cost-effective even its applies in the general
situation.
Non-intrusiveswitching:
The HK Series Electric actuators utilizes
magnetic induction mode switching without any shafts penetrating
the shell.
Non-intrusivesetting:
The actuators operational parameter setting are effected using
the non-intrusively, hand held, infra-red setting tool.
Double sealed:
All the HK series actuators are housed in a double-sealed
enclosure and provide complete protection to the internal
equipment even if the terminal cover are removed during site
wiring, the type of waterproof actuator can running *8 hours
while the actuator immerge into water deep 3 meters.
Torque protection:
A sensor serve as overload protection for the entire valve
travel, and you can setup a different torque volume between
*0~**0% of rated torque, in addition the open torque protection
value can be different from close torque.
Limitprotectionsetting:
If this function is enable, the actuator shall be stopped
automatically while the valve position reaches the limit
position.
Loss Phase protection:
The actuators real time monitor all three phase of the power
supply during operation to prevent the motor from running
when the power supply is short of phase.
Electronic Latching :
Electronic Latching inhibits the actuator torque protection
function within 5 seconds and allows the motor to generate torque
in excess of rated torque to enable operation of jammed valves
while starting operation signal is enable , should the actuator
stall when attempting to unseat a valve stuck in its seat, the
motor will be de-energised to prevent damage.
Motor thermal protection:
Two thermostats are embedded in the windings for provide
thermal-protection by de-energise motor in the event of motor
over the maximum temperature.
Electric protection:
The and output signal channel of circuits are designed as
photoelectric isolate mode.
Valve position and torque measure:
Use hall effect magnetic pulse system continually monitoring the
valve position and use the magnetic flux and current of the motor
for continually measures the controlling torque are to avoid the
mechanical wearing and ensure function stability.
Automatic correction for phase sequence:
The actuators monitor the phases and run in the correct direction
regardless of the sequence of power supply connection that is
realized through a phase rotation correction Boolean logical
calculation .
Setting the following configurations with infra-red setting tool
² Direction
to close
² Close
limit position protection function
² Close/
open operation torque value
² Open
/close limit position
² ESD
Optional function (ESD: Emergency shut down)
Digital indication of valve position:
The percentage digital of valve position real time indicates on
LCD display.
Power failed protection:
If main power failed, the internal battery of the actuator should
supply power for control circuit and supports valve position
control in hand operation. In case of no battery available,
actuator can save the currently valve position Data as well.
Handwheel operation:
Direct drive handwheel to provide reliable emergency manual
operation in the event of a power supply failure. Electric
operation always has the higher priority than manual operation,
when motor is energized that the operation state automatic switch
to electric operation mode unless hand/auto lever is purposely
locked into ‘manual operation’
Explosion proof:
The actuators has high class enclosure which is designed
according to GB***6, it provides reliable ingress and seals
guarantee. In addition, the threaded is designed at the cable
entry conduit of the actuator for fixing explosion proof
tube.
High torque, low inertia motor:
The low inertia and high torque motor generates peak torque
rapidly after starting but with very little overrun when it is
de-energized.
Lubrication:
HK series are filled with high-quality gear oil, the most
important machine parts such as worm and turbine operates in an
oil bath to reduce wearing and extend life.
Standard valve/actuator interface:
Actuator Base of ranges HK*3 to HK*0, designed as a removable
mode and Series HK**0 to HK**0 as an integral mode, the flange
and drive bushing conforming to international standard ISO***0
Thrust bearing configuration:
The type ‘A’ is the thrust type drive bushing that couples a
fully sealed and lubricated thrust bearing to guarantee which
have not any load effects on the actuator inner structure.
Solid state circuit measure:
All of Series HK provides the solid state circuit to measure the
torque without any mechanical equipments such as the spring
switch or the level.
Hurko valve actuator have Basic,Modbus-Rtu,Profibus,FF and ect
type.
