How to Adjust the Excitation Force of a Linear Vibrating Screen

The linear vibrating screen utilizes a horizontal vibration motor. Adjusting the excitation force is relatively complex, and methods vary slightly depending on the specific type of vibration motor. The detailed procedure for adjusting the excitation force of this linear vibrating screen is outlined below.

1. When the Excitation Force is Below 30% or 50%

1) Loosen the fastening bolts securing the vibration motor shields and remove the shields from both ends.

2) On this type of vibration motor, the outer eccentric block is adjustable. The scale markings on its surface indicate the percentage relative to the maximum excitation force. The inner eccentric block is fixed and secured to the motor coupling using fastening bolts. Datum lines are engraved on both ends of the rotating shaft.

3) Tighten the compression bolts on the outer eccentric blocks at both sides. Rotate the outer eccentric blocks in the same direction until the marking line on the shaft aligns with the corresponding excitation force scale marking on the outer eccentric block, thereby achieving the desired excitation force level.

4) Securely tighten the compression bolts of the outer eccentric blocks, reinstall the protective covers, and complete the excitation force adjustment.

2. When the excitation force is greater than or equal to 30% or 50%

1) Loosen the fastening bolts of the vibration motor shield and remove the shields from both ends.

2) The outer eccentric block of this type of vibration motor is a fixed block, secured to the shaft with a key and cannot be rotated. The inner eccentric block is adjustable. A scale indicating the percentage of maximum excitation force is installed on the outer surface and pressed onto the motor shaft by a fastening bolt.

3) Tighten the bolts securing the inner eccentric blocks on both sides. Rotate the inner eccentric blocks on both sides in the same direction until the excitation force scale on the inner eccentric block aligns with the slot on the outer eccentric block, adjusting it to the required .

4) Tighten the compression bolts of the inner eccentric block, install the protective cover, and complete the excitation force adjustment.
