Why the hydraulic cylinder surface wet

       

We all know that the hydraulic cylinder sealing elements in the tankof liquid, some how wet outside? We need to know, this hydraulic tools cylinder. The following is a look at what the problem:

       

1， In the hydraulic cylinder assembly time may be the end of theinstallation side of the cap piston rod center is not in the cylinder,the piston rod can not move, but also contribute to the destruction of the seal.

       

2, the track surface and the hydraulic cylinder on the bench,not parallel, causing the piston rod movement difficulties.

       

3, install the seal scratches the sealing lips attack lipdamaged or chamfer dimension is wrong, or wrong, is not installedseal.

       

4, the gland is not installed, used to tighten the screws did notlike the force.

       

5, the seals placed too long aging failure; the store did not put away, breakage or deformation; poor quality and sample size.

       

6, the piston rod and the groove is not handled properly.

         

7, oil, or other mixture of oil, the viscosity is too low.

       

 8, on the surrounding environment is too high, resulting insome high temperature.

         

9, the normal vibration.
