The belt is too tight or the coupling is poorly assembled and in a bad state. Here you can adjust the belt tension and calibrate the coupling for repair.

Rolling INA bearings are classified according to the type and number of rows of rolling elements, the direction of the load they can bear, and whether they have automatic self-aligning function.

At the friction points between the crankshaft and the bearings, the crosshead and the slide plate, the packing and the piston rod, etc., the temperature exceeding the specified value is called overheating. The consequences of overheating: one is to accelerate the wear between the friction pairs, and the other is that the heat of the overheating continues to accumulate until the friction surface is burned and the lock is burned, causing major machine accidents. The main causes of bearing overheating are: uneven fit between the bearing and the journal or too small contact area; deflection of the bearing, bending and twisting of the crankshaft; too low viscosity of the lubricating oil, blockage of the oil circuit, failure of the oil pump, etc.; during installation There is no leveling, no clearance is found, the main shaft and motor shaft are not aligned, the two axes are tilted, etc.

During the operation of the compressor, some malfunctions and even accidents will inevitably occur. A fault refers to an abnormal situation that occurs during the operation of the compressor. Once eliminated, the compressor can resume normal operation, while an accident refers to a damage situation. The two are often related, and if a fault is not eliminated in time, it will cause a major accident.      Compressor is a machine used to increase gas pressure and transport gas. From an energy point of view, a compressor is a machine that converts the power energy of the prime mover into gas pressure energy. With the development of science and technology, the application of pressure energy has become increasingly widespread, making compressors one of the indispensable key equipment in many sectors of the national economy. During the operation of the compressor, some malfunctions and even accidents will inevitably occur. A fault refers to an abnormal situation that occurs during the operation of the compressor. Once eliminated, the compressor can resume normal operation, while an accident refers to a situation of damage. The two are often related, and if a fault is not eliminated in time, it will cause a major accident.

During the use of the machine, some noise will be generated more or less. Some of it is unavoidable, but some noise must be solved immediately once it is generated, otherwise it will affect the operation of the machine, make the production unable to operate normally, and cause unnecessary losses.
