Pulleys work should pay attention to the pulley belt tension and wear at work sometimes strange noises such as rustling, squeaky, rushing sound, etc., driving without timely replacement, and sometimes cause large swings mediated round belts accelerated wear pulley design, sometimes referred belt belt grinding wheel stuck, sometimes pulley itself off, the belt off the tank and so on. So pay attention at work to check: case pulley belt wear, but also pay attention to check the operation of the engine belt mediated wheel. If there is abnormal and should be replaced Bushes even have to replace the belt wear is not serious engine belt-mediated round. Why pulley malfunction? Pulley Pulley reason malfunction during use, due to the equipment used for too long or design errors and other causes of failure of the timing belt wheel. Years of practical experience pulley drawings remind you, because pulley failure made the following conclusion: Because the pulley in the production process to rigorous quality control, in line with the size of the strength of long-term production requirements. However, due to improper handling can cause tooth think of this situation. Due to a large number of teeth in the process of carrying the tooth root out the extent of bending strength is maximized. Followed by the root causes of tooth marks by section will focus on the intensity of the teeth, causing tooth fatigue fracture pulley drawings, Hengda Machinery (certified), the pulley is provided by the Texas Hengda Machinery Limited.
