Jaw Crusher machine used reducer faults and treatment

(1) gear sound does not operate properly: gear bad gear worn or broken teeth; bearing worn or damaged; tooth surface adherent; there is debris inside of the box; bearing clearance is too large.

method:

adjusted gear meshing, changing gears and bearings; drain clean and carefully check box; adjust the bearing clearance.

(2), gearbox overheating: lubricants are not clean;crusher machine lubricants are not qualified; oil too much, poor cooling.

method:

cleaned, fresh oil change; drain excess oil clear the

crusher machine reduction gear box of floated coal debris such as heat dissipation.

crusher machine motor fault and dealing method

(1) that may occur motor not starting: power supply not connected, winding circuit breaker; winding grounding, the winding connection errors or short circuit between phases control equipment wiring error, melt blown.

processing method:

crusher machine check switch, and melt body, and each contact points and the motor leads threads; will circuit breaker parts heating to insulated grade allows of temperature, makes paint softening, then will line provoked, with with specifications line will broken off part fill welding, package good insulated, again by coated paint, and drying processing; melt body cut area too small, right select melt body; correction wiring, will load adjustable to rated value; motor single-phase up moving, check power.

(2) motor power not start, buzz: excessive crusher machine motor load or card power supply cannot be switched on; the voltage is too low.

method:

check the device, troubleshooting; with a multimeter check the power cord disconnected or false failures, and then fix the; power cable voltage drop caused by too much when the voltage is too low, should be changed into a thick cable line.

(3) motor enclosure for live: motor winding is damp, insulated serious aging lead line and the junction box grounding.

method:motor drying and aging of insulation you want to update; dressing or update lead wire insulation, fix the junction box.
