Feeder safety standards

Safety eode for vibration feeder

GB 16791 - 1996

1 Subject Matter and Scope

This standard specifies the feeder design, manufacture, installation, maintenance of basic security requirements.

This standard applies to electromagnetic vibrating feeder, vibrating feeder inertia and other forms of feeder device itself, does not include such equipment to connect the components.

If the device is used to transport hazardous, toxic and other hazardous materials, to the user when used in the order declared by the manufacturer, the manufacturer shall submit installation units shall comply with the special security conditions.

3 design, manufacturing

3.1 GB 5083 feeder should be designed to comply with the 1.1, 1.3 and 1.6 of the regulations,

3.2 should ensure that the equipment under normal operating conditions with sufficient strength, and should take into account the dynamic stress effects.

3.3 bolts should have a reliable anti-rotation.

3.4 Feeder must meet to stop working when the transport of materials do not fall.

3.5 pairs of mechanical moving parts, especially the inertia of the rotating eccentric vibrator protective devices should be set.

3.6 In the fully closed device should be fitted with self-locking device with inspection holes or live cover.

3.7 Feeder value not greater than the no-load noise 85 dB (A).

4 Installation

4.1 to be installed at the feeding trough plate and on the device.

4.2 feeder hanging rack or support should have sufficient stiffness, to avoid boom-degree contacts with other objects.

4.3 mobile rack mounted on the feeder should be equipped with a stop device. Additional wheel in the operator easy access by the protective devices should be added.

4.4 When the operator must remain in the mobile device must be installed platform, the platform should be able to prevent the operator in contact with any obstacle.

4.5 When the mobile feeder channel running along the unprotected alarms should be installed.

4.6 Feeder must be grounded to protect.

5 operation, maintenance

5.1 users should install the maintenance manual provided with the operating conditions, should avoid overload.

5.2 channel running along the mobile feeder, when the speed exceeds 0.10m / s, the operation must start in the audio-visual warning devices.

5.3 Electromagnetic vibrator must not collide in the core and the convergence of the state run.

5.4 inertia vibrator eccentric shield shall not remove the state run.

5.5 caused by a blockage or other reasons need to clean up, you must stop and start the feeder device after closure.
