ON-LINE INSPECTION CHECK LIST Visual inspection only
Exciter Gearbox
-
Check and record exciter oil level using correct dipstick. Inspect magnetic drain plug for indication of bearing flakes similar to fish scales. Replace seal washer & plug (torque plug to required tension).<br>Oil level should be checked prior to start up of screen, or in case of continuous operation, screen should be stopped for a sufficient length of time to allow all oil to drain to the bottom of exciter housing.<br>Note: Torque settings for drain plugs fitted with copper seal washers<br>M16-80nm M 24-170nm<br>Check lubrication table for correct oil levels.<br>OIL TO BE REPLACED EVERY 4 WEEKS<br>LH-______mm, RH-______mm<br>LH exciter serial number.....................<br>RH exciter serial number.....................
-
Check for any indication of excessive oil leakage from the exciter.<br>NB: Labyrinths will shed grease when exciter is new.<br>DO NOT re-grease Labyrinths; they are replenished by oil from the seals.
-
Check Exciter holding down bolts are all in position and tensioned if applicable.<br>Check Exciter lid and cover bolts are all in position and tensioned.<br>Check Exciter housing for damage.<br>Exciter Bolt tension if required for exciter replacement –<br>M30 8.8 = 1450Nm<br>M30 10.9 = 1800Nm
Screen Drive and Drive Shafts
-
Check Motor and lay shaft mountings for any indication of fatigue, corrosion or looseness.<br>Repair as required.
-
Check Drive & Intermediate Drive Shaft and coupling connections for possible loose or missing bolts.<br>Check for corrosion or damage.<br>Remove guards if necessary.<br>Drive shaft bolt torque-<br>M12 8.8 = 84Nm<br>M12 stainless = 75Nm
-
Check Drive Shaft & Intermediate spline for possible free play.<br>Replenish grease 30g, every 6 months.
-
Check Vee Belt Guards, Drive Shaft Guards, Intermediate Guards and Exciter Guards for damage.<br>Check for build up of material on feed side of intermediate shaft guards (remove if present).<br>Check guard bolts are all in position and tensioned.
-
Check Lay Shaft and Bearings for shaft movement.<br>Replenish grease 20g each / Monthly
-
Check condition of drive belts, check belt tension, adjust tension to specification if required
-
Check drive pulleys for wear, damage or looseness.<br>Taper lock bolt tension- 22Nm
Screen Body
-
Check screen body for loose or missing bolts.<br>Replace bolts as required.
-
Check all beam end doublers for corrosion or fatigue.
-
Check side plates internally & externally for corrosion or cracks.<br>Check back plate for corrosion or cracks.<br>Check all external stiffeners and all fasteners.
-
Check for possible interference between screen body and stationary hoppers, chutes, and building beams.
-
Check for possible interference between screen body and material build up in chutes.
-
Check side clamp bars and back plate liners for wear and security.
-
Check exciter beam externally for cracks or corrosion and product build-up.
-
Check external paint system for damage and signs of erosion / corrosion.
