Hydraulic fitting leakage is unavoidable in the process of hydraulic system installation. XCD machinery hereby reminds us that the following 10 points should be paid attention to during subsequent inspection or maintenance and replacement, otherwise it may cause incalculable and serious consequences.
1, Do not use the hand to check whether leakage.
Hydraulic oil temperatures often reach 150℃ or more, which can quickly cause severe burns.
2.Don't try to solve the leakage problem just by tightening the nut.
In only a few cases, liquid leakage is caused by nut loosening. Excessive tightening will destroy the integrity of the fitting, which is one of the common causes of fittings leakage.
3.Do not bring a pressure check system.
Be sure to relieve pressure on the system before performing an inspection, even if the liquid is slow. This will minimize the risk of a burst of hydraulic oil injection on the mechanical component during the inspection.
4.Do not change the type of fittings to save time or cost.
Make sure to replace exactly the same type of connector, randomly find a similar replacement, is one of the causes of failure.
5.Don't always suspect the fittings.
The dripping point may not be the leakage point, the liquid dripping occurs at the lowest point, although the liquid may drip at the fitting, the actual leakage point may be elsewhere.
6.Do not reuse o-rings.
When reassembling reusable fittings, o-rings should be replaced in a timely manner. O-rings are prone to cracks, which can damage the sealing performance of the system during reassembling.
7.When fixing leaks, don't forget to protect open systems.
When repairing a leak, if the disassembled fitting is left on the ground and then reinstalled, it can introduce contaminants into the hydraulic system and shorten the service life of the equipment.
8.Don't forget to clean the connector when replacing or reinstalling it.
This helps prevent dirt and metal burrs from entering the hydraulic system, particles that can damage expensive hydraulic parts.
9.The halogen light.
All open flames should be kept away from the leak point, including lit cigarettes, lighting with lighters, and using welds nearby.
10.Don't ignore any minor problems.
Even a minor leak can be a sign of more serious hydraulic system problems.
