Hot sale self loading concrete truck is an advanced concrete mixer truck type, it can achieve automatic loading, mixing and unloading process. Which can minimize the adverse effects of time on concrete, and can be produced at any time and can be used at any time, completely eliminating the process of concrete mixing plant. With the mixing capacity of 1.5-6.5 cubic meter, self loading concrete truck mixer is welcomed on the small size project and road construction.

In fact, shaft end sealing has always been a common problem in the design and manufacture of self loading concrete truck mixer at home and abroad. In order to improve the technical content of concrete truck mixers as soon as possible, improve the shaft end sealing problems of mixers, improve the performance of the whole machine, and enhance market competitiveness, our company has developed After searching for information from many sources, the design team focused on the principle of shaft end seal and put forward new design ideas:
1, Change the sealing form, adopt the form of floating seal and grease seal, forming four mechanical seals in the front and back;
2, Change the contact surface form between the sealing ring and the inner floating seal seat;
3, The sealing ring is made of special material, which improves the sealing effect and prolongs the service life of the seal; 　
4, The refueling system uses four vertical pump cores to supply oil to the four shaft heads respectively, which avoids the blockage of the diverter valve and reduces the workload of repair and maintenance;
5, Lubricating oil detection points are installed at the shaft end of self loading concrete truck to detect whether the lubricating grease actually reaches the shaft head.
