one.Explosion proof precision small electric actuatoroverview

The BR series compact electric actuator is a new generation product developed by our company through the introduction of new technology. Special design, new numerical formula, high intelligence, high protection performance, small size, high integration, long service life, stable performance and other characteristics. It can be operated on-site or remotely controlled, suitable for controlling 0270 ° rotation doors and other similar products. Such as screws, ball valves, wind dampers, plug valves, louvers, etc. Can meet various requirements of industrial automation control management. Widely used in various industries such as petroleum, chemical metallurgy, water treatment, shipbuilding, papermaking, power plants, printing and dyeing, food processing and pharmaceuticals, and machine automation systems.

two.Explosion proof precision small electric actuatorProduct Performance

The explosion-proof structure of the BR series compact explosion-proof products complies with GB3836.1-2000 "Electrical Equipment for Smoke and Explosive Gas Environments Part 1: General Requirements"; The smoke proof shell composed of explosion-proof components of the product can withstand the explosive pressure generated by the smoke explosion of explosive gas mixtures inside the shell, and can block the spread of smoke explosion inside the shell to the smoke explosion gas environment outside the shell. The explosive gas mixture that does not spread to the outside of the shell when an explosion occurs inside the product.

three.Explosion proof precision small electric actuatorExplosion proof product on-site cable Installation requirements for conduit

1. There are two smoke prevention heads at the wiring inlet of the wiring cavity. When users connect wires, they should remove one or two wall prevention heads according to their needs

And install smoke proof connectors that are compatible with the incoming power supply, with a diameter of 514mm for the incoming power supply,

2. The power line and signal line should be respectively introduced into the electric actuator from two smoke proof connectors and require grounding, while the value line should be grounded

To use a screen cable

3Remove the explosion-proof wall head, install a smoke proof connector that is compatible with the incoming power supply, and tighten it

4Unscrew the compression nut of the smoke proof joint, insert the incoming power from the acid plug, tighten the nut, and insert the smoke proof joint into the interior of the electric actuator.

5. Connect according to the control circuit diagram,

6. Tighten the compression nut so that there is no gap between the sealant and the electrical joint

7. The outer diameter of the incoming wire should be equal to the aperture inside the smoke proof joint, and a single wire that does not meet the smoke proof requirements should be used instead

8. It is necessary to properly ground the internal and external lights of the executing agency,

9. The description in this manual is only one form of anti smoke circular splicing joint. Users can also choose other electric ropes, joints, and wiring methods that meet smoke prevention requirements according to their needs.
