How to solve the problem of cutting machine oil leakage

Reason 1: Honggang's cutting machine is poorly assembled

(1) The end cap of the Honggang cutting machine hydraulic cylinder is misaligned, the piston rod is not concentric with the cylinder, which makes it difficult to extend the piston rod and accelerates the wear of the seal.

(2) The poor parallelism between the hydraulic cylinder of the Honggang cutting machine and the guide rail surface of the workbench makes the piston difficult to extend and accelerates the wear of the seal

(3) The installation of the seal of Honggang cutting machine is incorrect, such as the seal is scratched or cut off, the sealing lip is reversed, the lip is damaged or the shaft chamfer is not the correct size, the seal is incorrectly installed or missing

(4) The sealing gland of Honggang cutting machine is not installed properly

     1) Gland installation has deviation

     2) Uneven force on fastening screws

     3) The fastening screws are too long, so that the gland cannot be compressed.

Solution:

(1) Disassembly inspection, reassembly

(2) Disassembly inspection, reinstall, and replace the seal

(3) Replace and reinstall the seal

     1) Reinstall

     2) Reinstall and tighten the screws to make the force uniform

     3) Reasonably select the screw length according to the depth of the screw hole

Reason 2: The quality of Honggang's cutting machine seal

(1) The storage period is too long, and the seals naturally age and fail

(2) Poor storage, deformation or damage

Reason 3: The viscosity of the oil in the Honggang cutting machine is too low

(1) Wrong oil used when changing hydraulic oil

(2) Oils of other brands are infiltrated in the oil. It is recommended to replace the appropriate oil.

Reason 4:  Honggang's cutting oil temperature is too high

(1) The resistance of hydraulic cylinder inlet is too large

(2) The ambient temperature is too high

(3) The pump or cooler is faulty

Troubleshooting:

(1) Check whether the oil inlet is unblocked

(2) Take insulation measures

(3) Check the cause and eliminate

Reason 5: High-frequency vibration of Honggang cutting machine

(1) Loosen fastening screws

(2) Loose fittings

(3) Installation position moves

Troubleshooting:

(1) Regularly tighten the screws

(2) The joints should be tightened regularly

(3) The mounting screws should be tightened regularly

Reason 6: The piston rod of Honggang cutting machine is injured

(1) Dust ring aging, failure to invade dirt such as sand chips, etc.

(2) The fit between the guide sleeve and the piston rod is too tight, which will cause the heating surface to overheat, causing the chromium layer on the surface of the piston rod to fall off and cause injury.

Troubleshooting:

(1) Clean and replace the dust ring, repair the damaged surface of the piston rod

(2) Check and clean. Use a scraper to repair the inner diameter of the guide sleeve to achieve the matching clearance.
