Release Time：2021-01-25
Scraper conveyor has the advantages of firm structure, convenient installation, reverse operation, arbitrary point in and out, self-take, self-delivery, etc., and has become an important transportation equipment in coal mine production. However, due to the harsh working environment, scraper conveyor is prone to fatigue, wear, fracture and other failures, affecting production. What is the cause of motor failure of scraper conveyor? Let's take a look!

However, due to the harsh working environment, scraper conveyor is prone to fatigue, wear, fracture and other failures, affecting production. What is the cause of motor failure of scraper conveyor? Let's take a look!
1. Fever
Cause analysis: fever is mostly related to poor heat dissipation effect such as excessive dust absorption by the fan, excessive load, lack of oil or damage to the bearing, non-conformity of coaxiality, large vibration, excessive selection of fuses (pieces), etc.
Countermeasures: remove dust at the air inlet of the fan, eliminate overload factors, replace damaged bearings, adjust coaxiality, fasten anchor bolts, and select fuses (pieces) to meet the requirements of motor parameters, etc.
2. Rattle
Single-phase operation, the bearing of scraper conveyor is damaged, the load is too heavy or the sheet is too large, and the top fall causes the conveyor to be crushed to death.
Countermeasures: check the phase line, eliminate single-phase hidden dangers, replace damaged bearings, and eliminate overload factors.
3. The starting of the motor of the scraper conveyor is not normal.
The reasons are: overload; The working parts are jammed; The coal mining face is uneven. Low power supply voltage; Transformer capacity is small; The delay between the nose and tail motor is too long, resulting in single machine dragging. Motor failure.
Countermeasures: eliminate overload factors; eliminate blocking; flatness working face; adjust the power supply voltage; replace the transformer with suitable capacity; readjust the delay between motors; replace the motor.
The above is for you to introducescraper conveyorThe cause of the motor failure, I hope it will help you!
