Common faults of tubular-belt conveyor: analysis and comprehensive countermeasures

Side travel and twisting of tubular-belt conveyor can lead to shutdown, damage and shortening of service life of the conveyor. Aiming to finding an effective solution to the common faults, based on analysis of the factors leading to the faults, integrated countermeasures are adopted, such as taking precautionary measures to guard against occurrence of belt side-travel and twisting faults, adding auxiliary cleaning units, improving design of electrical control devices and strengthening routine and periodical inspection and maintenance service. Practice shows that with implementation of the integrated measures, the fault rate of the conveyor has been effectively decreased; the time required to deal with a minor belt misalignment fault is reduced to less than 10 minutes; the service life of the belt is prolonged by 50 percent; the common fault occurring during operation of the conveyor have been eliminated; and the automatic monitoring and protection level has been notably enhanced, making it possible to effectively check a minor fault before it becomes worsening, conveyor ease remedial work, and maintain stable operation of conveyor.
