From the conventional situation, the construction capacity of the excavator after overhaul can surprisingly reach more than 80% of the new car factory. If there is no replacement of the new vehicle engine, coupled with various factors in the machine run-in period, the performance of the excavator vehicle will also be uneven.
At this time, we need to pay attention to the following points:
It is assumed that the cylinder is not equipped with cylinder liner, because some machines have the need for cylinder boring when overhauling the excavator, which will wear off the cylinder wall mesh, so it will cause poor oil lubrication in the cylinder. If you do not deal with such problems, it will even cause the repair of the machine sometimes worse than before the overhaul, here Kelit construction Machinery Co., Ltd. friendly tips: need to pay attention to the installation of cylinder liner.
There is also our choice of cylinder liner is also very particular, as far as possible to choose the mesh effect of good accessories. Some small factory cylinder liner usually does not have mesh technology, even if the effect is very unsatisfactory. On the contrary, the original parts usually use techniques such as mesh grinding and surface hardening, and such cylinder liner will have the following significant advantages: 1. There is basically no run-in period; 2. Effectively save the loss of excavator oil; 3. The oil of the excavator will be attached to the mesh groove, and the lubrication environment has been greatly improved than before, effectively improving the good performance of oil production; 4. Such a cylinder liner wear resistance has been well improved.
