The hollow pin chain is the most important component in production equipment. If the production equipment is used for a long time, there will be such and such problems. How to judge whether a hollow pin chain needs to be replaced?
The scrapping of hollow pin chain should be judged from the following aspects: firstly, the operators should be clear that the allowable wear value of hollow pin chain is limited, and generally speaking, it cannot be higher than 10% of the diameter of circular chain bar. Second, it depends on the degree of distortion of the main ring of the hollow pin chain. If it is greater than 10 degrees, it is scrapped. Of course, this is calculated from the plane above the main ring that is not curved. If the hanging chain of the hollow pin chain is used for a long time, cracks, bending and other phenomena will occur. If it cannot be removed after elimination, it cannot be used again and is counted as scrap.
Once the hollow pin chain has problems, it will bring great trouble to the production. Then we must do a good job in daily maintenance and repair in our life, and strive to reduce the damage of equipment. First of all, when installing the sprocket on the shaft, it is necessary to ensure that there will be no swing and inclination. When the sprocket in the same transmission assembly is not rotated again, it will be located in the same horizontal plane. If there is any deviation, it is necessary for professional technicians to repair it.
The tightness of the hollow pin chain should be appropriate, not too tight or too loose. If the hollow pin chain is too loose, the power of the equipment will increase and excessive consumption will occur. If the hollow pin chain is too loose, the equipment will easily jump or even trip. However, the chain that has been used for a long time should not be mixed with the new chain, so as not to generate impact and break the chain during use.
