After the installation of the coal mining scraper conveyor is completed, a trial operation should be carried out. The operation should be from the component to the component, from the component to the single machine, from the single machine to the entire conveyor line, manually first and then motorized, from low speed to high speed, gradually increasing the load from no load to Operation is performed in the order of rated load operation.
The coal mining scraper conveyor shall meet the following requirements in the no-load trial operation:
(1) No-load trial operation can be carried out when the other parts of the coal mining scraper conveyor meet the requirements;
(2) The adjustment of the tensioning device should be flexible, and the scraper chain should not slip when the coal mining scraper conveyor starts and runs;
(3) When the scraper chain of the coal mining scraper conveyor is running, there should be a certain gap between its edge and the chute, and there should be no deviation;
(4) The operation of the driving device should be stable, and the scraper of the coal mining scraper conveyor and the scraper chain should be in good contact on the track;
(5) Good engagement between the sprocket and the scraper chain;
(6) The oil temperature and bearing temperature rise of the speed reducer and hydraulic coupler of the coal mining scraper conveyor should not exceed the requirements of the equipment technical documents, and the lubrication and sealing should be good;
