Motor fault

A motor can't immediately after starting or starting to slow down:

Line fault

2, electric control system to protect atresia

3, speed (strip) protection installed improper adjustment

4, the voltage drop

5, contactor fault, check the line b, check the running deviation, limit and stop along the road

Such as protection, accident treatment, make its reset c, d check speed device, check the voltage

E, check the overload relay

Two motor overheating

1, due to the overload, card resistance on super length or conveyor belt, make run overload running

2, due to the transmission system, and the bad lubrication condition in motor power increased

3, in the motor fan inlet or the radial heat dissipation in the accumulation of dust, worsen cooling conditions

4, double motor, because of different motor characteristic curve or roller diameter difference, the shaft power distribution uneven

Frequent operation

A measurement, motor power, identify the reasons for overload operation, symptomatic treatment

The transmission part b, add lubrication in a timely manner

C, removal of dust,

D, the power of the motor, make the characteristic curve of converged, by adjusting the coupling oil charge amount, makes the reasonable motor power with e, reduce operating frequency

Conveyor belt failure

1 wandering

2 an old-fashioned, cracking and burrs

Friction conveyor belt and frame, belt, pull hair, crack b, conveyor belt and fixed hard objects interference c, improper safekeeping tension is too large

3, prevent the conveyor belt on a fixed member or fall into the metal components in the conveyor belt

4, according to the requirements of conveyor belt custody storage, avoid using short laid

Adhesive tape

With body material does not adapt, encounter water, encounter cold hard brittle

2, conveyor belt use for a long time, intensity variation

Conveyor belt joint quality, local cracking failure to repair a, choose mechanical and physical performance and stable

Material made with core, timely replacement of damaged or aging of the conveyor belt c b, the joint often observed, found the problem

Processed in a timely manner

And material

Serious overload, guide chute keep-off wear rubber apron, feed channel steel plate too narrow, rubber apron is longer than the other

2, concave segmental arc radius of curvature is small, make the conveyor belt produces impending, deformation small a groove, control, transmission capacity, strengthen the maintenance,

Maintenance, design b, as far as possible the more concave segmental arc radius of curvature; Length does not allow, can be in concave segment with several groups

When running deviation of the material

4, unreasonable design of material

Roller fault

Roller is not turn

There is no contact roller and conveyor belt

Roller shell material card, or roller end face contact with roller bearing interference

Roller can not seal, bearing caused by dust into the jam

Roller bearing a poor lubrication, high cushion roller location, and transportation

Machine b, remove material contact, add washer interference in parts or a roller bearing, make face c, apart from contact roller, clean or replace the bearing, reassemble the d, use the special lubrication of roller

Abnormal noise

1 redirection roller and driving roller bearing worn timely replacement of bearing abnormal noise

2 different coupling two axis heart in the noise Adjust motor and speed reducer shaft concentricity

Three roller serious eccentric roller of a noise, manufacturing seamless steel tube wall thickness is not uniform, section to beat too b, both ends of bearing hole when machining center and the outer circle circle heart bigger deviation
