6 Maintenance and

Troubleshooting

Chapter outline

Even though the small conveyor units require little maintenance, it pays to check

the general state of the units in regular intervals in addition to the regular cleaning

of the exterior (see Chapter 5), and carry out maintenance if required.

Problems usually crop up during the installation and commissioning procedures.

This chapter helps you during troubleshooting and helps you avoid problems by

giving preventative advice.

6.1 Preventative maintenance

As a matter of principle, the AViTEQ small conveyor drives and associated equip-

ment are maintenance-free. The units are designed to ensure that the properties of

the materials are retained even under the high vibrational stress during long-time

continuous operation.

Check on a weekly basis:

Does the small conveyor drive cause excessive noise? Establish the cause to

prevent damage to the equipment (see below)!

Are there any deposits of the material transported? Establish why - otherwise

the throughput will be affected! Deposits are caused by condensation proces-

ses or by problems with the material’s recipe.

Check after six months of operation:

ã Are the spring mounting bolts on the narrow side of the small conveyor drive

tight? They could have loosened due to the vibrations. In this case, thighten

the bolts with the specified torque (see Table 7.3). If this affects the adjust-

ment of the eigenfrequency or the air gap, the small conveyor unit must be

realigned by AViTEQ.

ã What is the state of the rubber feet underneath the small conveyor drive? Is

the rubber porous or cracked? If so, all rubber feet of the small conveyor drive

must be exchanged.

ã What is the state of the working unit? Is the surface already significantly ero-

ded? If required, the working unit must be replaced. Ensure correct weight of

the working unit, so that the vibration adjustment is not affected!
