What are the classification and fault diagnosis methods of chemical mixer?

　　Chemical mixer has many classifications, which is widely used in industry, which greatly facilitates the production in industry. However, some faults will appear in the process of use. Many friends are not particularly aware of the maintenance methods and diagnostic methods of these faults. Next, this paper will Let us share some information about classification of chemical mixer and fault diagnosis method. I hope you can like it.

　　1、 Classification of chemical agitators

　　Chemical agitators are divided into forced mixer, concrete mixer, vertical mixer and new type mixer.

　　1. Forced mixer

　　The machine includes planetary mixing mechanism, eddy current mixing mechanism, mixing drum, discharge mechanism, mixing frame and bottom frame. The center position of the drum is equipped with eddy current mixer. On both sides of the vortex mixer, two planetary mixers and two planetary mixers are symmetrically arranged on both sides of the agitator The vortex mixer and drum rotate in reverse direction. The stirring force of the machine is large, so the problems of the unity bin are solved.

　　2. The concrete mixer includes a power mechanism connected with the transmission mechanism through the shaft and a drum driven by the transmission mechanism. The drum body is equipped with a gear ring arranged around the cylinder body, and the transmission shaft is provided with gears engaging with the gear ring. The utility model has simple and reasonable structure. After the gear and gear ring are meshed, the sliding phenomenon between the supporting wheel and the mixer drum can be effectively overcome in rainy and fog weather; the transmission mechanism adopted can further ensure the elimination of the slip phenomenon between the supporting wheel and the mixer drum.

　　The mixer can also be divided into: Star mixer, risk prevention mixer, vertical mixer, concrete mixer, double shaft mixer, single axle mixer, antiskid concrete mixer.

　　3. Vertical mixer

　　The mixer includes a motor, a mixing drum, a transmission shaft and a mixing blade. The shaft sleeve of the reverse mixing blade is connected with the sprocket at the upper end of the intermediate shaft on the side of the transmission shaft through the chain, and the passive gear which is coaxial with the sprocket is meshed with the active gear fixed at the lower end of the transmission shaft. The two mixing blades of the utility model rotate in reverse direction, so that during the mixing process, the raw materials can form convection between the two mixing blades, thus completely solving the problem that the traditional mixer stirs the raw materials without mixing.

　　4. new mixer

　　The new mixer is a replacement product, which is an irreplaceable product of mixing equipment in chemical and building materials industries. It has realized the correct "mixing and mixing" coming out, thus eliminating other mixing equipment and thus bearing the important task. It fills the international gap with its unconventional conception, excellent technical content and reasonable design level. It is widely used in paint, paint, dye, leather making, medicine, beverage, adhesive, food, washing products, cosmetics and various solid objects. There is inexhaustible wealth. The mixing effect of the dispersion, emulsification, homogenization and color matching of the objects is more ideal and intuitive than that of the traditional mixer, which is a revolution in the mixing industry.

　　2、 The fault diagnosis method of chemical mixer

　　Chemical mixer also encountered some faults in the process of use, the most typical is abnormal sound problem. When this kind of fault occurs, the equipment makes a big noise, which can be heard at a place more than ten meters. The check current is within the normal range, and it is difficult to find the problem if simple inspection. The whole equipment of chemical mixer can be divided into three parts: mechanical seal assembly, gearbox and motor, and it can be separately inspected and analyzed.

　　1. Inspection of mechanical seal assembly

　　The most easy failure of chemical mixer is the mechanical seal part, which often fails mechanical seal due to wear and water enters the sealing cavity. Firstly, the mechanical seal assembly is decomposed, and the parts including two sets of mechanical seal, skeleton oil seal, output shaft, bearing, shell and end cover are cleaned and inspected. The relevant dimensions of bearing pedestal and output shaft of mechanical mixer are checked. If no problems are found, it indicates that the mechanical sealing part is in good condition and the possibility of troubleshooting is eliminated.

　　2. Analysis and inspection of gearbox

　　Some agitator equipment have high processing accuracy and good heat treatment. Thoroughly clean the gearbox, carefully check the gears, gear shafts and bearings. It is found that the gear surface is smooth, free of pitting and intersection, the meshing side clearance of gear is normal, and the tooth profile is free of obvious wear; the radial and axial clearance of each bearing is normal, and there is no pitting spot on the inner and outer rings and roller surface, and the overall quality is good; the axial clearance of each axle is reasonable, and the output shaft of the handplate is free of movement, no shell jam and abnormal sound. Then, the gearbox can be corrected.

　　3. Inspection, analysis and treatment of motor failure

　　Motor failure performance of chemical mixer: before disassembling the motor, air transport shall be carried out to find out the problem. If the motor of the mechanical mixer makes abnormal sound and vibration is very big; hissing sound is made at the shaft sleeve of the motor shaft of the mechanical mixer. The motor can reach dozens of degrees in less than 2 minutes by air transportation, and the temperature of shaft extension reaches dozens of degrees, and the motor is scalded. The internal bearing inner ring of the mechanical mixer has pear skin pitting area due to pitting. The surface is rough, dim and lustrous. The pitting hole can be seen obviously; the inner ring of the skeleton oil seal is damaged; the inner ring of the bearing and sleeve of the mechanical mixer has dark spots formed by "running ring" at the corresponding journal.

　　Because of pitting of inner ring of chemical mixer, pear skin pitting area is formed. When bearing roller passes through, it has obvious sticking phenomenon and sound. This may be the root cause of abnormal noise of the motor inside the chemical mixer, so the problem can be solved by replacing the bearings in the mixer.

　　Above is the classification of chemical mixer and what is the fault diagnosis method shared by you today. More problems can be paid attention to us.
