Safety Operating Procedures for Shared Belt Conveyor

Whether the screws of motor, coupling, reducer and bearing seat are complete and loose.

Explanation of spinning technology

There are two kinds of spinning forming: ordinary spinning and powerful spinning. The spinning that does not change the blank thickness but only the blank shape is called ordinary spinning; That is, the spinning that changes the thickness and shape of the blank is called strong spinning. The spinning pressure required for powerful spinning is large, and the structure of spinning machine is generally complex. According to the movement direction of spinning wheel and metal, the power spinning forming can be divided into positive spinning forming and reverse spinning forming. The direction of motion of the rotating wheel is the same as the direction of metal flow, which is called positive rotation; Conversely, it is called anti rotation. For the same material, reverse spinning requires a lot of spinning. The spinning method shall be determined according to the shape and process requirements of the parts.

Causes of belt pulley wear

Those who often use the pulley know that as a cast iron, the pulley is easy to rust. At this time, many friends asked me whether the belt pulley was rusty and affected the use? Will rust on the pulley surface accelerate belt wear? For this problem, I can tell you for sure that the rust on the pulley surface will not affect the use, nor accelerate the wear of the belt.

What's wrong with the abnormal noise of the pulley?

During the operation of power generation, you may sometimes hear the belt pulley making noise, such as rustling, squeaking, and gurgling. At this time, you should pay attention to the noise of the belt pulley. The most common situation is that the surface of the belt pulley has skidding or open space due to long-term wear.

The secrets that the pulley has to tell

Belt pulley is a kind of disc hub part with relatively large relative size, and its manufacturing process is generally mainly casting and forging. Generally, the larger size is designed by casting method, and the material is generally cast iron (with good casting performance), but rarely cast steel (with poor casting performance of steel); Generally, the smaller size can be designed for forging, and the material is steel. Pulleys are mainly used for long-distance transmission of power, such as the output of small diesel engines, agricultural vehicles, tractors, automobiles, mining machinery, mechanical processing equipment, textile machinery, packaging machinery, lathes, forging beds, transmission of power of some small horsepower motorcycles, transmission of power of agricultural machinery, air compressors, reducers, reducers, generators, ginning machines, etc.
