Performance characteristics
1、 Overview of electric actuator products
Lmp-a series produced by lmtork is a new and powerful intelligent multi turn electric actuator. Lmp-a series intelligent multi turn electric actuator is suitable for gate valve, globe valve, diaphragm valve and various regulating valves. Widely used in power plants (hydropower, thermal power, nuclear power), oil (gas) fields, refineries, steel, chemical, (sewage) water treatment, pharmaceutical, shipping, paper, heating, building automation and other industries.
The power supply uses AC380V / 220V / 110V (non-standard customized) as the driving power, switching signal (active and passive) and 4-20mA current signal as the control signal to make the valve move to the required position and realize its automatic control. The maximum output torque reaches 5000n · M.
2、 Performance characteristics of electric actuator
2.1 shell
The shell is made of hard aluminum alloy, anodized and coated with polyester powder, with strong corrosion resistance and protection grade of IP67. IP68 and B flameproof type are available for selection (please specify when ordering).
2.2 motor
Totally enclosed squirrel cage motor is adopted, which has the characteristics of small volume, large torque and small inertia force. The insulation grade of the motor is f and the built-in overheat protector can prevent the motor from being damaged by overheat.
2.3 dryer (optional)
It is used to control the temperature, prevent moisture condensation inside the actuator due to temperature and weather changes, and keep the internal electrical components dry.
2.4 indicator
The indicator is mounted on the central axis to observe the valve position. The mirror adopts toughened glass convex lens design, no water, more convenient to observe.
2.5 valve position control
Realize the effective combination of mechanical counter and absolute value encoder, the valve position control is more accurate and reliable.
2.6 torque protection
Mechanical and electronic overload protection can be selected. When the valve is jammed and there are foreign matters, the motor power supply can be automatically disconnected, which can more effectively protect the valve and electric actuator from damage（ It has been set before leaving the factory. Please do not change the setting at will.)
2.7 self locking
The precision worm gear mechanism can efficiently transmit large torque, high efficiency, low noise (up to 50 dB), long service life, and has self-locking function to prevent reverse rotation. The transmission part is stable and reliable, and there is no need to refuel.
2.8 simple debugging
The infrared setter can be used for simple, safe and fast non-invasive adjustment. The lmtork setter can be used to enter and adjust the actuator settings, such as torque value, limit, control and display functions.
Lmtork provides a unique setter, which can set the actuator non invasively.
2.9 phase sequence self correction and open phase protection
The rotation direction of the actuator can be set freely, and the phase sequence of the power supply can be corrected automatically. The phase sequence of the power supply does not need to be considered in wiring. It also has the protection function of power supply phase loss and output phase loss.
2.10 signal free configuration and self diagnosis
There are 8 output contacts in total, 4 contact signals for users to choose, each signal can be defined freely, and the other 4 contact signals cannot be defined freely. Powerful fault self diagnosis function, convenient for users to deal with faults in time and quickly, and master the operation status of equipment.
2.11 bus technology
There are modbus, PROFIBUS and other bus communication modules.
2.12 installation
The bottom mounting size meets the international standard of ISO5211, the drive shaft sleeve can be removed and processed according to the needs, with strong adaptability. It can be installed vertically or horizontally.
2.13 lines
The control circuit meets the standard of single-phase or three-phase power supply, the circuit layout is compact and reasonable, and the terminal can effectively meet the requirements of various additional functions（ It can be processed separately according to customers' requirements.)
2.14 split control
The control unit of the actuator can be installed separately from the mechanical parts to solve the problems of high temperature, high altitude installation and debugging
