Can the hydraulic cylinder be repaired after it is broken?

Irreversible damage to hydraulic cylinders is generally rare, but occasionally problems such as scratches may occur during use. To reduce maintenance costs and improve efficiency and benefits, it is necessary to find out the cause of oil leakage in hydraulic cylinders. Business managers must also master how to repair cylinders. This is very important. Different hydraulic cylinder scratch repair technologies have advantages. Not the same, the following editor will tell you the conventional repair methods after the hydraulic cylinder is scratched and leaked.

Conventional repair methods after hydraulic cylinder scratches and oil leakage

1. Preliminary cleaning and preparation

First of all, the first step in repairing the hydraulic cylinder after oil leakage is to remove the oil. Specifically, it is to clean the oil on the metal surface. Note that the use of strong corrosive cleaning agents is not allowed, otherwise it will greatly affect its service life. It is generally recommended to use an angle grinder to perform preliminary treatment on the scratched part, and then a special person will grind the groove along the steel cylinder wall. The dovetail groove is the best as the basis for repairing under the hydraulic cylinder.

Second, choose composite repair

Since there are many composite materials for hydraulic cylinder repair, we will not introduce them one by one. For example, nano-polymer composite materials are generally applied to the entire repair site according to the prescribed method, and manual repeated pressing is required. However, no matter what hydraulic cylinder is selected The repairing materials must ensure that the materials are filled and reach the specified thickness. They must be slightly higher than the cylinder wall of the hydraulic cylinder, otherwise they will not have the effect of repairing fu, and they will be easily damaged after repair.

Three, curing and sealing

Due to the different repair materials selected, there must be differences in the post-processing. For example, the nano-polymer composite material repair hydraulic cylinder is used as an example, and the halogen lamp is used for heating to cure, improve the curing effect, shorten the time, and wait until the repair material After curing thoroughly and reaching the specified hardness, repair the standard surface with stone moistened water, and ensure that the professional hydraulic cylinder is airtight as a whole.

The above is only a general repair technique after the hydraulic cylinder is scratched, and the specifics need to be determined according to the actual situation. If you want to avoid the hydraulic cylinder from leaking, you need to perform daily maintenance, and watch the hydraulic cylinder scratch repair. For example, if you want to avoid hydraulic cylinder damage, you must purchase professional products in the early stage. High-quality hydraulic cylinder products can greatly reduce the chance of damage and maintain stable work for a long time.
