PRODUCT STRUCTURE

1 Integrated control unit Non-sunk switch button is adopted to ensure complete waterproof function. The built-in circuit board has a reliable power isolation from external interference signals by optical isolation elements. If there is an over-torque switch induction, for the safety of the motor and valve, the actuator will refuse to be sensed by other sensors before the operator inputs the home position (RESET) button.

2 Selection of control mode

The selective switch "Remote"-"Stop"-"Local" installed on the local operating device can be used to set up remote operation (remote control) or local operation (local control) or stop mode.

3 Local electric operation

The operating switch "Open"-"Close" installed on the local operating device can be used to open or close actuator locally.

4 Motor

The valve-specific motor that can be disassembled independently has the characteristics of high starting torque and small inertia. The squirrel cage induction motor with embedded thermostat. The built-in thermostat accurately detects the increased temperature to prevent form motor damaging.

5 Electric operation

The motor drives the electric worm through a first-stage spur gear pair, and the worm drives the eccentric shaft to rotate through the copper worm gear combined with it. This reduction gear structure has self-locking performance, when the motor stops, the valve will be locked in position.

6 Stroke control, torque control and opening indicating mechanism

Stroke control It adopts a cam mechanism, the cam shaft is synchronized with the output shaft and two micro switches are respectively set in the opening and closing directions.The upper end of the cam shaft is equipped with a dial to indicate the valve position. Torque control The electric worm is equipped with a butterfly spring group, the axial movement of the electric worm is proportional to the output torque of the output shaft, and the movement of the worm is converted into the rotation of the torque shaft through the rack and pinion structure. A cam is installed on the torque shaft, and a microswitch is provided correspondingly in the direction of opening and closing.

7 Manual operation

When the handwheel is turned, the manual worm drives the outer gear of the fixed ring gear to rotate, and the inner gear of the fixed ring gear and the planetary gear form a fixed-axis gear train to drive the output shaft to rotate. Therefore the manual and electric operation conversion of the actuators is completed through the role conversion of the static ring gear. There is no clutch, and there is no need to switch the handle to achieve fully automatic switching.

8 Terminal box

The independent sealed terminal cavity can ensure the sealing integrity of the electrical part of the electric actuator when performing on-site wiring, and at the same time meet the product explosion-proof requirements.

9 Mechanical limit

There is an adjustable limit screw in each direction of opening and closing. A special sealing gasket is installed on the limit screw to ensure good sealing performance of this part.

PROTECTION GRADE CAN BE CUSTOMIZED

What is the Electric Actuator Protection Grade?

IP (INGRESS Protection) protection grade system is drafted by IEC (International Electrotechnical Commission) and classifies the electrical appliances according to the characteristics of its dustproof and humidity. The IP protection grade is composed of two numbers. The first number represents the grade of electrical dustproof and the grade of preventing foreign objects from invading (the foreign objects referred to here contain tools, and human fingers cannot be exposed to the inside of the electrical appliances. In order to avoid electric shock), the second number indicates the degree of conflict of moisture and waterproofing in electrical appliances. The larger the number, the higher the protection grade.

The protection grade is one of the important parameters of the valve electric actuator. Different protection grades and prices are different. Generally speaking, the protection grade is represented by IP00, and the two numbers behind IP represent the size of the protection grade. So what does these numbers mean? What are the different protection grades different?

First, the first number indicates the level of contact protection and the protection grade of foreign objects (protection scope)

0 - No protection. 1 -Protective 50mm diameter and larger solid external body.

2 -Protective 12.5mm diameter and larger solid exterior.

3 - Protecting 2.5mm diameter and larger solid external body.

4 -Protective 1.0mm diameter and larger solid exterior.

5 - Protective dust cannot be completely prevented from entering the dust, but the number of dust entry will not cause damage to the equipment.

6 - The closed dust is completely prevented from invading foreign objects and can completely prevent dust from entering. The second number represents waterproof protection level (protection scope)

0 - No protection.

1 - water droplets falling vertically, water droplets should not cause damage.

2 -When the water drop cabinet is tilted to any side of the 15 degrees, the droplets falling vertically should not cause damage.

3 -The water sprayed from the 60 -degree angle of the vertical line of the protection sprayed should not cause damage.

4 -Water that splashed water splashed from every direction should not cause damage.

5 -The water that protects the sprayed water from each direction to the water ejected by the nozzle of the cabinet should not cause damage.

6 - Protective strong radiation water should not cause damage to the strong ejection water from each direction.

7 - When the protection of water is immersed in the water for short -term immersion in the water for a short time, ensure that it is not damaged due to water.

8 - Long -term protection of protection can be immersed in water under specific conditions to ensure that it is not damaged due to water.

Protection Grade Certificate

Industrial automation is the foundation of industrial modernization, and plays an important role in traditional industrial reform and the adjustment and optimization of industrial structure. With the development of computer network communication technology and electronic electronic technology, the industrial automation control system is constantly optimizing and updating. In the face of increasingly complex production processes and environments, the requirements for valve controllers are also increasing to meet the requirements of modern automation production.

In this case, it is necessary to correctly grasp the quality of the product, do a good job of protection testing, and ensure the quality of the control valve.

IP68 is the highest level of waterproof level standards. Everyone knows how the waterproof performance of the controller depends mainly on the latter two digits XX of the IPXX. The first x is from 0 to 6, and the highest level is 6; the second place X is from 0 to 8, the highest level is 8 is 8, the highest level is 8 is 8, the highest level is 8 is 8, and the highest level is 8. ; Therefore, the highest waterproof level of the controller is IP68. In other words, IP68 controller is the highest standard controller of waterproof level, and IP68 is undoubtedly a good benchmark for the improvement of product quality.
