As more and more factories adopt automation control, manual operations are replaced by mechanical or automated equipment. People demand that the actuator can play an interface role between the control system and the mechanical movement of the valve, and also require the actuator to enhance work safety performance and environmental protection performance. In some hazardous situations, automated actuator devices can reduce personnel injuries. Some special valves require emergency opening or closing in special circumstances, and the valve actuator can prevent further spread of danger while minimizing factory losses. For some high-pressure large-diameter valves, the required output torque of the actuator is very large. In this case, the required actuator must improve mechanical efficiency and use a high output motor to operate the large-diameter valve smoothly.

Spare parts 33820 CAT

A device, also known as an actuator, that uses electrical energy, compressed air, or pressure oil as power to output angular or linear displacement corresponding to the control signal, and drives the regulating mechanism with a certain torque or thrust to complete the production process parameter control requirements. According to the different power sources used, there are usually electric actuators, pneumatic actuators, hydraulic actuators, etc. The actuator is an important component of the automatic control system. It receives control signals from control instruments or manually given signals, amplifies their power, and then converts them into corresponding angular or linear displacements of the output shaft to drive various regulating mechanisms, such as regulating valves, air dampers, etc., to change the flow rate of the regulated medium and achieve automatic or manual control of various process parameters. The action pattern of the actuator is usually linear, and there are also cases where an equal percentage type is used. Its control signals include continuous current signals, as well as intermittent voltage signals or pulse signals. [1]

The current actuators are electric signal pneumatic long stroke actuators and electric actuators.

Electric signal pneumatic long stroke actuator

Pneumatic actuators powered by compressed air and capable of directly receiving standard current control signals have the characteristics of smooth operation, high thrust, high precision, inherent explosion-proof, and easy implementation of required control laws. Most of its varieties come with a "three break" self-locking function for power, gas, and power signals, ensuring high safety during use. [1]

Figure 1 is a schematic diagram of the pneumatic actuator. The pneumatic actuator consists of two main parts: an automatic working system and various auxiliary devices. The former includes components such as electric pneumatic converters, locators, cylinders, connecting rods, etc., while the latter includes manual operating mechanisms, "three break" self-locking devices, valve position transmitters, travel switches, etc. The electric pneumatic converter converts the current control signal into an air pressure control signal. The function of the automatic working system composed of a locator that works according to the principle of force balance and cylinders and connecting rods as power components is to correspond the output angular displacement of the actuator with the input control signal. Hand operated mechanisms are used for device adjustment and on-site emergency operations. The "three break" self-locking device consists of a monitoring circuit for gas source, power source, and electrical signal, as well as a locking device when the gas source is cut off. When one of the above faults occurs, the actuator outputs a hold position to ensure the safety of the equipment and operation. The valve position transmitter converts the output angular displacement of the actuator into a corresponding current signal, and the travel switch is used to issue a switch signal for the limit position.

Pneumatic actuators with "three breaks" protection are widely used in various industrial sectors. But its structure is complex and requires a large amount of maintenance work. Common pneumatic actuators include those with only air source protection function, pneumatic diaphragm regulating valves, pulse electric signal pneumatic long stroke actuators, etc. The first two have a simple structure, while the latter uses pulse control and has good safety.

Electric Actuator

There are two main categories: angular travel and straight travel. According to different signal systems and full travel times, it is divided into basic varieties and multiple derived varieties. In the automatic control system, they are used with different models of electric operators to achieve automatic control of process parameters, manual/automatic bidirectional disturbance free switching of the control system, intermediate limit and remote manual operation functions. [1]

The electric actuator consists of two main components: a servo amplifier and a servo mechanism. Figure 2 shows the schematic diagram of the electric actuator. It is a position automatic control system. The deviation between the control signal from the control instrument and the valve position feedback signal returned by the position transmitter is amplified by the servo amplifier, and then the servo motor is driven to drive the reducer to push the adjustment mechanism to rotate in the direction of reducing the deviation. The output shaft is finally stabilized at the angle position corresponding to the control signal. The function of the electric operator is to perform manual/automatic switching and remote manual operation of the control system.

In order to successfully achieve process automation, the most important thing is to ensure that the valve itself can meet the special requirements of the process and the medium inside the pipeline. The production process and process medium usually determine the type of valve, the type of valve core, as well as the structure and materials of the valve internals and valves.

After selecting the valve, the next step is to consider the requirements of automation, that is, the selection of the actuator. The actuator can be considered simply based on two basic types of valve operation.

1. Rotary valve (single turn valve)

This type of valve includes: plug valves, ball valves, butterfly valves, and dampers or baffles. This type of valve requires an actuator that can rotate 90 degrees with the required torque

2. Multi turn valve

This type of valve can be a non rotating lifting stem or a rotating non lifting stem, or they require multiple rotations to drive the valve to the open or closed position. This type of valve includes: straight through valve (globe valve), gate valve, knife gate valve, etc. As an option, pneumatic or hydraulic cylinders or membrane actuators with linear output are also used to drive the aforementioned valves.

There are currently four types of actuators that can use different driving energy sources and operate various types of valves.

1. Electric multi turn actuator

Electric driven multi turn actuators are one of the types of actuators. Using a single-phase or three-phase motor to drive gears or worm gears, and finally driving the valve stem nut, the valve stem nut causes the valve stem to move and open or close the valve.

Multi turn electric actuators can quickly drive large-sized valves. In order to protect the valve from damage, the limit switch installed at the end of the valve stroke will cut off the motor power supply. At the same time, when the safety torque is exceeded, the torque sensing device will also cut off the motor power supply. The position switch is used to indicate the on/off status of the valve. The handwheel mechanism installed with the clutch device can manually operate the valve in case of power failure.

The main advantage of this type of actuator is that all components are installed in one housing, which integrates all basic and advanced functions within this waterproof, dustproof, and explosion-proof shell. The main disadvantage is that in the event of a power failure, the valve can only remain in its original position, and only with the use of a backup power system can the valve achieve a fail safe position (fail open or fail closed)

2. Electric single rotary actuator

This type of actuator is similar to an electric multi turn actuator, with the main difference being that the final output of the actuator is a motion of 1/4 turn to 90 degrees. The new generation of electric single turn actuators combines the complex functions of most multi turn actuators, such as parameter setting and diagnostic functions using a non intrusive user-friendly interface.

The single turn actuator has a compact structure and can be installed on small-sized valves, with a typical output torque of up to 800 kilograms per meter. Additionally, due to the small required power supply, they can be equipped with batteries to achieve safe operation in case of failure.

3. Fluid driven multi turn or linear output actuators

This type of actuator is often used to operate straight through valves (globe valves) and gate valves, which use pneumatic or hydraulic operation methods. The structure is simple, the work is reliable, and it is easy to implement a fault safe operation mode.

Usually, people use electric multi turn actuators to drive gate valves and globe valves, and only consider using hydraulic or pneumatic actuators when there is no power supply.

4. Fluid driven single rotary actuator

Pneumatic and hydraulic single turn actuators are very versatile, they do not require power and have a simple structure with reliable performance. They have a wide range of applications. Usually, the output ranges from a few kilograms of meters to tens of thousands of kilograms of meters. They use cylinders and transmission devices to convert linear motion into right angle output. The transmission devices usually include forks, gears and racks, and levers. Gears and racks output the same torque throughout the entire stroke range, making them highly suitable for small-sized valves. Forks have high efficiency and high torque output at the beginning of the stroke, making them ideal for large-diameter valves. Pneumatic actuators are generally equipped with accessories such as solenoid valves, positioners, or position switches to control and monitor valves.

This type of actuator is easy to implement a fail safe operating mode.

When selecting a suitable valve actuator type and specification, the following factors must be considered:

Drive energy

The driving energy source is either a power source or a fluid source. If a power source is chosen as the driving energy source, a three-phase power source is generally used for large-sized valves, while a single-phase power source can be used for small-sized valves. Generally, electric actuators can have multiple types of power sources to choose from. Sometimes DC power supply is also optional, and in this case, power failure safe operation can be achieved by installing batteries.

There are many types of fluid sources. Firstly, they can be different media such as compressed air, nitrogen, natural gas, hydraulic fluids, etc. Secondly, they can have various pressures. Thirdly, the actuator has various sizes to provide output force and torque.

Valve Type

When choosing a valve actuator, it is necessary to know the type of valve in order to select the correct actuator type. Some valves require multi turn drive, some require single turn drive, and some require reciprocating drive, which affect the selection of actuator types.

Usually, multi turn pneumatic actuators are more expensive than electric multi turn actuators, but reciprocating linear output pneumatic actuators are cheaper than electric multi turn actuators.

Torque magnitude

For valves with a 90 degree rotation, such as ball valves, disc valves, and plug valves, it is best to obtain the corresponding valve torque from the valve manufacturer. Most valve manufacturers test the required operating torque of the valve at rated pressure and provide this torque to customers. For multi turn valves, the situation is different. These valves can be divided into: reciprocating (lift) motion - valve stem non rotation, reciprocating motion - valve stem rotation, non reciprocating - valve stem rotation. The diameter of the valve stem must be measured, and the size of the valve stem connection thread determines the actuator specification.

Selection of execution mechanism

Once the type of actuator and the required driving torque for the valve are determined, the data sheet or selection software provided by the actuator manufacturer can be used for selection. Sometimes the speed and frequency of valve operation also need to be considered.

The fluid driven actuator can adjust the stroke speed, but the electric actuator with three-phase power supply only has a fixed stroke time.

Some small-sized DC electric single turn actuators can adjust their travel speed.

switch control

The biggest advantage of automatic control valves is that they can be operated remotely, which means that operators can sit in the control room to control the production process without the need to physically operate the valve on site. People only need to lay some pipelines to connect the control room and the actuator, and the driving energy directly excites the electric or pneumatic actuator through the pipeline, usually using a 4-20mA signal to feedback the position of the valve.

Continuous control

If the actuator is required to control parameters such as liquid level, flow rate, or pressure in the process system, which requires frequent action of the actuator, 4-20mA or 0-10V analog signals can be used as control signals. However, this signal may change as frequently as the process. If a very high-frequency actuator is required, only select a special adjustable actuator that can start and stop frequently. When multiple actuators are required in a process, digital communication systems can be used to connect them together, which can greatly reduce installation costs. Digital communication circuits can quickly and efficiently transmit instructions and collect information. There are currently multiple communication methods such as FOUNDATION FILDBUS, PROFIBUS, DEVICENET, HART, and PAKSCAN designed specifically for valve actuators. Digital communication systems can not only reduce investment costs, but also collect a large amount of valve information, which is very valuable for predictive maintenance programs of valves.

predictive maintenance

Operators can use the built-in data storage to record the data measured by the torque sensing device during each action of the valve. This data can be used to monitor the operation status of the valve, prompt whether the valve needs maintenance, and diagnose the valve.

The following data can be diagnosed for valves:

1. Friction force of valve sealing or packing

2. Friction torque of valve stem and valve bearing

3. Friction force of valve seat

4. Friction during valve operation

5. The dynamic force acting on the valve core

6. Friction force of valve stem thread

7. Valve stem position

Most of the above data exists for all types of valves, but the emphasis is different. For example, for butterfly valves, the frictional force during valve operation can be ignored, but for plug valves, this force value is very large.

Different valves have different torque operating curves. For example, for wedge valves, the opening and closing torques are very large, while during other strokes, only the friction force of the packing and thread is present. When closing, the hydrostatic pressure acts on the gate plate, increasing the friction force of the valve seat. Ultimately, the wedge effect causes the torque to rapidly increase until it is fully closed. So, based on the changes in the torque curve, it is possible to predict the faults that will occur, which can provide valuable information for predictive maintenance.

Intelligent frequency conversion control

During the operation of the actuator, the frequent starting of the motor causes a change in the rated frequency during operation. Intelligent frequency conversion control can be used to achieve the rated frequency

For example, due to resistance or external forces, the starting speed of the motor slows down, resulting in errors in the stroke control of the actuator. By using intelligent variable frequency control, the input speed can be changed, making the operation of the actuator more reliable and stable

Generalized executive agency

Li Xuerong proposed the concept of generalized actuator in 1988, which has two main starting points: 1) in order to develop machines with better performance, it is necessary to expand pure mechanical mechanisms and develop novel generalized actuators that extend the functions of traditional mechanisms; 2) Generalize the components that make up the organization. On this basis, Zou Huijun provides a more precise definition of a generalized actuator based on the development trend of modern machinery: a generalized actuator is a controllable actuator composed of a driving unit and an executing unit, which is the executor of the machine's mechanical energy conversion, motion generation, and conversion functions, and is the core of the mechatronics system. [2]

Basic characteristics of generalized executive agencies

(1) Controllability: Generalized actuators integrate mechatronics through sensing technology, electronic technology, control technology, etc. They can achieve complex and variable output movements by programmable control of driving components according to changes in functional requirements, transforming the original "rigid" output into a "flexible" output and achieving diversity in output movements.

(2) Intelligence: By using intelligent driving components such as shape memory alloys, the output motion of the mechanism is made intelligent, achieving intelligent control of the machine.

(3) Miniaturization: Through the action of micro motors, piezoelectric crystals, etc., the mechanism can generate micro scale working stroke, achieving miniaturization of the mechanism.

(4) Integration: With the development of modern mechanism technology, "motion integrated blocks" that can achieve various motion outputs, such as linear displacement units, can be designed and manufactured.

(5) High performance: The motion output of a generalized actuator is related to the characteristics of the driving components and the type of mechanism, rather than simply depending on the type of mechanism. Modern driving components include various forms such as motors, hydraulic cylinders, pneumatic cylinders, piezoelectric actuators, electromagnetic switches, shape memory alloys, etc. Their driving characteristics are different from traditional single power sources. Expanding the connotation of the mechanism into an integrated body of driving components and mechanisms transforms the designer's design space from a one-dimensional design space to a two-dimensional design space that simultaneously designs driving component parameters and mechanism structural parameters while considering their integration. Designers have more design parameters to enhance the motion and dynamic performance of the mechanism and expand its functionality.

Application of Generalized Execution Mechanisms

(1) Sewing equipment

For over a hundred years, people have continuously improved and innovated sewing machines, evolving from ordinary foot operated household sewing machines to multifunctional industrial sewing machines. After entering the 1960s, the development of sewing machines began to apply electronic technology, resulting in the emergence of mechatronics integrated sewing machines. This new type of sewing machine uses controllable motors and microprocessors to control the sewing process, improving the flexibility of the sewing machine. At present, it is a consensus among industry insiders that sewing equipment should develop towards the direction of electromechanical integration. Many people believe that in order to make the movements of the four major mechanisms, as well as the horizontal needle mechanism and the thread cutting mechanism, "arbitrary", such as changing the behavior of the needle bar, the trajectory of the thread hole, and the movement of the horizontal needle, using only "traditional mechanisms" is powerless, and "electromechanical motion technology" must be sought to improve the performance of sewing equipment.

(2) Camera focusing system

A camera consists of a lens, shutter, aperture, focusing device, viewfinder, film winding mechanism, and box body. Due to the widespread application of mechatronics technology in this field, a large number of complex internal mechanisms have been replaced by integrated circuits, drive motors, and electromagnetic actuators. Cameras have evolved from traditional products that combine precision machinery and optics to automated systems that integrate precision machinery, optics, and microelectronics technology.

(3) CNC milling machine

In CNC milling machines, servo motors, gear reducers, and screw mechanisms are mainly used as prime movers, transmission mechanisms, and execution mechanisms. The output motion of the servo motor is controlled by using a servo control system to compensate for the motion error of the screw mechanism. The application of generalized actuators makes the input motion of the spiral mechanism a nonlinear function, which can effectively improve the three-dimensional accuracy of the output motion and thus enhance the overall performance of the machine tool.

(4) Metal Forming Press

In the design of metal forming presses, a two degree of freedom planar seven bar mechanism was driven by a mixture of high-power constant speed motors and low-power servo motors. This hybrid driven press has excellent performance and can achieve low-cost numerical control of the press. In addition, Muratec Corporation in Japan adopts a servo drive system to improve the working performance of the press, which uses a servo motor to control the working mode of the punch
