How long is the running in period of the new pipe chain conveyor accessories?
The new machine or the machine with overhauled chain in the pipe shall go through a running in period at the initial stage of operation. The running in period is one month, which is mainly divided into the following stages;
1) The chain in the pipe shall be inspected every day for one week (six days). If the chain is found to be loose (judged by the method described in Item 2 of Article 2), it shall be tightened immediately;
2) In the second week, the chain in the pipe shall be checked every day. If the chain is loose, it shall be expanded. If the worn push plate, chain plate and cotter pin are found, the cause of the fault shall be found first. If the cause (such as large block stuck between the two chain plates, round pin shaft deformation, etc.) is found, it shall be replaced;

3) The third and fourth weeks shall be checked twice a week to observe the wear. If there is serious damage, the cause shall be found out first and then replaced. If the chain in the pipe is loose, it shall be expanded and tightened in time;
4) After a month, check and repair once a week to ensure that the chain is properly tightened and the machine runs smoothly.
5) the operator should check every part of the conveyor every day, especially the chain and drive device in the pipe should be in good condition. Once damaged parts are found, they should be repaired or replaced in time.
6) During operation, a grate grid shall be set at the feeding port to strictly prevent iron blocks, steel plates, welding electrodes and sundries from mixing into the conveying mechanism, so as to avoid damaging the equipment or causing other accidents.
7) Pay attention to keep the transmission part in good operation, and open the cover plate once a week to check the service condition of the bearing.
8) When the feeder is installed in the pit, there shall be waterproof and drainage devices in the pit, and appropriate positions shall be reserved for cleaning and maintenance.
