What is the standard for the integrity of conveyor reducers?
(1) The reducer housing has no cracks or deformations, the joint surface is tightly matched, and there is no oil leakage;
(2) The reducer rolls smoothly without any abnormal noise;
(3) Clean the reducer grease with an appropriate amount of oil.
2
Possible causes and solutions for hydraulic coupling slippage of scraper conveyor after startup.
(1) Insufficient working fluid should be replenished;
(2) Chain compression should remove the load of compressed chain goods;
(3) The card chain should be cleaned of any defects;
(4) There are many instances of counterfeits, and the problem of counterfeits should be eliminated.
3
What are the factors causing fuel injection ignition due to the failure of the fusible alloy plug in hydraulic couplings using oil as a medium?
(1) Replace the easily melted gold plug with other materials;
(2) The melting point of the fusible alloy plug is too high;
(3) The device position of the fusible alloy plug is incorrect (equivalent to raising the melting point);
(4) Metal powder or other impurities in the working fluid block the passage between the easily melted gold plug and the inner cavity of the hydraulic coupling;
(5) The flash point of the working fluid is too low.
4
What are the factors causing overload of hydraulic couplings in scraper conveyors?
(1) The scraper chain is overloaded due to pressure chain, jamming chain, chain out of groove, etc;
(2) The coaxiality error between the hydraulic coupling of the electric motor and the input shaft of the reducer is too large (not concentric);
(3) There is a problem with the reducer.
5
What records should conveyor drivers keep?
(1) Handover record;
(2) Work records;
(3) View, repair, and experiment records;
(4) Record the incident.
6
What is the content of the "six no starts" for scraper conveyor drivers?
(1) The signal is unclear and cannot be turned on;
(2) Someone on board is not driving;
(3) The conveyor is overloaded and cannot be opened;
(4) Unclear factors of the problem cannot be identified;
(5) There are foreign objects on board that cannot be opened:
(6) The device is not in good condition and cannot be turned on.
