Types, basic parameters and dimensions of silo wall vibrators 1 Subject content and scope of application
This standard specifies the types, basic parameters and dimensions of silo wall vibrators. JB/T 3002-94
Replaces JB3002-81
This standard applies to electromagnetic and inertial silo wall vibrators installed on the silo wall of bulk material silos to cause local vibration of the silo wall, destroy material arching and promote material flow.
2 Types and codes
2.1 Silo wall vibrators are divided into two types according to their structure: electromagnetic type and inertial type. Both types of silo wall vibrators can be made into explosion-proof types according to explosion-proof requirements.
2.2 Model indication methodbzxZ.net
Exciting force code, N×10-1
Type code: electromagnetic type is not indicated, inertial type is G Silo wall vibrator code
2.3 Marking example
Example 1 Electromagnetic silo wall vibrator with exciting force of 500N: silo wall vibrator CZ50JB/T3002-94
Example 2 Inertial silo wall vibrator with exciting force of 1000N: silo wall vibrator CZG100JB/T3002-94
