How to do the leakage of oil in the hydraulic cutting machine?


The leakage of hydraulic oil from the cutting machine of Ponse

Cause one: bad assembly of Ponse's cutting machine

(1) When assembling the hydraulic cylinder of Ponse Cutting Machine, the end cover is offset and the piston rod is not aligned with the cylinder barrel, which makes it difficult to extend the piston rod and accelerates the wear of the seal.

(2) the parallelism between the hydraulic cylinder of the Ponse cutting machine and the guide surface of the worktable is poor, which makes the piston difficult to extend and accelerates the seal wear.

(3) the installation error of the confidentiality seal of Ponse, if the seal is scratched, cut off, the seal lip is fitted, the lip is damaged or the size of the shaft chamfer is incorrect, the seal is misplaced or leaked.

(4) the sealed cap of Ponse cutting machine is not installed

1) the mounting of the cap is biased

2) unevenness of fastening screws

3) the fastening screw is too long to press the cap to press tight

Troubleshooting methods:

(1) dismantled and reassembled

(2) disassemble inspection, re install and replace seals.

(3) replace and reinstall the seal

1) reinstall

2) reinstall and tighten the screws to make the force uniform.

3) reasonable selection of screw length according to the depth of the screw hole

Cause two: the quality of the confidentiality seal of Ponse

(1) the storage period is too long, and the seals are naturally aged.

(2) keeping, deforming, or damaging

Reason three: the viscosity of oil in the cutting machine of Ponse is too low

(1) the wrong oil is used when the hydraulic oil is replaced.

(2) the oil in the oil is permeated with other grades. It is suggested to replace the appropriate oil.



Cause four: Ponse's cutting oil temperature is too high

(1) the hydraulic cylinder inlet resistance is too large

(2) the ambient temperature is too high

(3) failure of pump or cooler etc.

Troubleshooting:

(1) check whether the inlet of the inlet is unblocked

(2) take insulation measures

(3) check the causes and exclude

Cause five: high frequency vibration of Ponse cutting machine

(1) loosening of fastening screws

(2) loosening of pipe joint

(3) install position to generate movement

Troubleshooting:

(1) the screws should be fixed on a regular basis

(2) regular fasteners should be fastened

(3) the mounting screws should be fixed on a regular basis

Cause six: the pull of the piston rod of the cutting machine of Ponse

(1) dust ring aging, failure to invade sand chips and other dirt.

(2) The fit between the guide sleeve and the piston rod is too tight, so that the moving surface is overheated, resulting in the chromium layer on the surface of the piston rod shedding and strain.

Troubleshooting:

(1) cleaning and replacing dust ring to repair the surface of the piston rod.

(2) check and clean, use scraper to trim the inner diameter of guide sleeve to match the gap.
