Now, we'd like to discuss more about the common irregularities and its solutions of JS series concrete mixer.Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:concrete mixer,concrete batching plants,concrete mixer,blocking making machine,concrete pump,etc.
1. The temperature of reducer is too high.
The main reason is generally that overloading of bearings increases, the friction aggravates and so, more heat is produced. This can be attributed to the viscosity of lubrication oil. It is because the viscosity of lubrication oil may cause the increase of reducer load. If the lubrication oil is with high viscosity, its flow ability becomes worse and the operating duty increases. In this process skid steer loader, a large amount of heat will be produced and lead to the temperature increase of reducer. On the contrary, if the viscosity of lubrication oil is low, its lubrication effect reduces and it adds the friction of parts. The reducer need to work done to overcome friction. This will also produce much heat and make the reducer heat up. In this case, please replace new appropriate lubrication oil.
2. The two shaft end of mixing barrel is over heat.
This is caused by severe friction of shaft end. The excess temperature of shaft end is because of damaged bearings or insufficient oil supply. The damaged bearings in mixing barrel are one of the main reasons for excess temperature. If the mixing shaft always works in a overloading condition, the bearings will be surely wore out or damaged. Once bearings are damaged, the friction between shaft and bearing will become severe and severe and it leads to overheat of shaft end. In this situation, new bearings need replacing. The friction between shaft and bearing also will become severe, when the lubrication oil is not enough, especially when concrete mixer is used for a long time and have low maintenance. To prevent shaft end of mixing barrel from excess temperature, we should take a regular maintenance to concrete mixer and add lubrication oil as required timely.
3. Leakage of shaft end.
The main reason for it is damage of floating seal. Shaft end of concrete mixer is loaded parts. Therefore, the service life of these parts will become much shorter. So, it is very important to maintain the parts of shaft end timely and replace the sealing elements properly. Replace new floating seal for continuous leakage of shaft end.
