Everyone should know that as long as it is the construction machinery parts industry, there will be pollution or damage, which is not considered to be caused, but what we need to do is to try our best to prevent the pollution and damage caused by the construction machinery parts. Now let's introduce the main common sense of the oil cylinder and the causes of the pollution and damage caused by the oil cylinder:
The oil cylinder is the main part of construction machinery accessories. The traditional processing method is: broaching the cylinder block - fine boring the cylinder block - grinding the cylinder block. The rolling method is: broaching the cylinder block - fine boring the cylinder block - rolling the cylinder block. The process is three parts, but the time comparison: grinding the cylinder block for 1 meter takes about 1-2 days, and rolling the cylinder block for 1 meter takes about 10-30 minutes. Input comparison: grinding machine or quilting machine, rolling knife. The surface hardness of the hole is increased by about 30%, and the fatigue strength of the inner surface of the cylinder barrel is increased by 25%. If the service life of the cylinder is only considered, it will increase by 2-3 times, and the efficiency of the boring and rolling process will increase by about 3 times compared with the grinding process. The above data show that the rolling process is very good and can greatly improve the surface quality of the cylinder barrel. After the oil cylinder is rolled, there is no sharp edge on the surface, and the long time movement friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.
The analysis of the causes of pollution and damage of the oil cylinder of engineering machinery accessories shows that these particles are often tiny. For a reliable hydraulic system, they can not be accumulated and suspended near the oil. The clearance is extremely necessary for the realization of limited tube bundles, importance and coarseness. The appearance of the small edge is not sharp, and the obstruction symptom is that after holding the vehicle when selecting agricultural tools at work, the longitudinal crack will be found in the middle of the upper part of the oil cylinder after disassembly. Do not remove the plug of the outlet before assembly. The reason why the debating ring or closed operation will be damaged after a long time may be the change and improper use of the hydraulic trivial appreciation of martial arts. The tank burst after rolling. It can greatly improve the appearance quality of the cylinder.
