Electric roller should always check, troubleshooting time. Below I will introduce the common failures and exclusion methods under electric drum.

The 1 motor current is low, and the cylinder does not rotate. Troubleshooting: check whether the motor is normal, if the motor is normal is likely to be the coupling pin shaft fracture, replacing the pin shaft after Rev machine needs care operation, prevent the failure because the pin as a non wear and tear and lead to more serious consequences.

The rotating parts of 2 drum left end cover and through coupling seepage oil. Troubleshooting: skeleton oil seal skeleton oil seal wear can be the spring ring tightening or to replace the skeleton oil seal.

The 3 end cap oil plug oil leakage. Troubleshooting: fastening oil plug, replace the oil resistant rubber pad.

The 4 end cap is connected with the cylinder is leaking. Troubleshooting: check the bolts is loose, check the ventilation plug and outlet channel whether blocking, dredging or cleaning.

5 junction box permeability (built-in drive). Troubleshooting: check the oil level is too high. Remove the junction box, tighten the oil seal plug.

6 drum noise. Troubleshooting: drum noise newly installed large should add table frame rigidity, also check the installation of coaxial cylinder, coupling and motor. The method is that the drum from the stent, a separate trial running roller, noise smaller, indicating the need to increase the rigid stent.

7 check the drum after the power is switched on, the drum rotation. Troubleshooting: power phase sequence error, should immediately disconnect the power to change the power supply wiring phase sequence, to achieve the correct phase sequence connection.

The 8 check type drum when the power supply is disconnected, the cylinder check. Troubleshooting: check the backstop whether faults exist or wear.
