1. Product Overview

Thirty years of focus on the field of industrial automation control in the development, production and maintenance of various actuators. Continuous integration of Chinese and foreign advanced technology and design concept, continuous improvement and innovation, to adapt to the changing market demand. Provide a complete product chain, provide optimized automatic control solutions, provide high-quality pre-sales and after-sales services, and provide customers with value-for-money products with professional practical experience.

The compact electric actuator is an economical product, which mainly highlights the advantages of compact structure, simple transmission, reliability, small size and light weight on the premise of meeting the basic main functions. Especially suitable for all kinds of small diameter valve automatic control. This series of electric actuators adopts die-cast aluminum alloy box body and shell, with powder coating on the outer surface, which can be applied to relatively harsh working environment. The protection level of the shell can reach IP68, and various working modes such as switch and adjustment can be realized. Standardized connection design is adopted. Can be easily assembled with a variety of valves. In line with JB/T8219-1999 "industrial process control and control system with electric actuator" technical standards.

4. product specifications and models

5. use requirements:

Use environment

1. This series of products are designed with IP67 protection grade, which is suitable for indoor and outdoor use under normal conditions. The ambient temperature is -20-60 ℃. If the equipment is immersed in water, IP68 type should be selected. If the temperature of the pipeline medium is high, it may be conducted to the equipment body, and an additional connecting bracket should be selected for installation to reduce heat conduction.

2. Pay special attention when connecting the power cord and control cable with the actuator to prevent external water from climbing into the body and external moisture from invading the body.

Travel and Control

1. The effective stroke (O-90 degree) of the control object (valve, damper, etc.) and the rotary motion of the actuator should be consistent, and the use of over-stroke is not allowed. To ensure mutual mechanical zero corresponding. If the lever connection is selected, it should be ensured that the trajectory of the connecting rod is a parallelogram.

2. The stroke protection of the actuator is signal (4-20mA), limit switch and mechanical limit, and a small margin should be left between the three protections.

3. Before using the equipment, check whether the equipment use environment (especially explosion-proof places), power supply and control mode are consistent, and pay attention to whether the wiring is accurate, especially the power supply and control line can not be connected incorrectly.

4. The remote control signal cannot be controlled by strong electricity. The product instruction manual should be read carefully before using the equipment.

Installation of 6. products

In order to accurately control, the matching accuracy of the transmission parts should be improved to prevent the transmission accuracy from being reduced due to excessive clearance. Serious may cause the product to not work properly.

1, the machine can be installed arbitrarily, there is no unreasonable installation location. The outlet hole faces down as much as possible.

2. The environment around the equipment should be avoided such as heat source, strong magnetism and strong corrosive gas. If it is not easy to avoid, corresponding isolation measures should be taken or corresponding products should be specially ordered.

7. Maintenance and Maintenance

Since the sealing material used in the product is rubber, attention should be paid to replacing the failed seals after long-term use. In order to ensure that the product has sufficient service life, for places with frequent actions, a certain amount of working torque should be selected.

A suitable working environment will increase the service life of the product.

2. Valves that do not work for a long time should be moved several times regularly to prevent corrosion and jamming of internal valves or transmission parts.

3, in the long-term vibration of the workplace should regularly check the effectiveness of fasteners, wiring, sealing and other parts.
