Precautions For The Use Of Heavy Duty Hydraulic Cylinder
As a part of heavy duty machinery, hydraulic cylinder plays an important role in the application. It is necessary to know the precautions for the use of it, so as to prolong the service life of the heavy duty hydraulic cylinder.
When using hydraulic cylinders, we must pay attention to protecting the outer surface of the piston rod to prevent bumps and scratches from damaging the seals. Nowadays, although some construction machinery hydraulic cylinders are designed with protective plates, we should usually pay attention to prevent bumps and scratches. In addition, it is also necessary to frequently clean up the mud and sand on the cylinder seal dust ring and the exposed piston rod to prevent the difficult-to-clean dirt stuck on the surface of the piston rod from entering the cylinder, thereby causing damage to the piston, cylinder or seal.
In normal use, we should also pay attention to frequently checking the connections of the threads, bolts, etc., and tighten them immediately if they are loose, because it will also cause oil leakage in the hydraulic cylinder.
Frequent lubrication of the connecting parts to prevent rust or abnormal wear in an oil-free state also requires attention. Especially for some parts with rust phenomenon, it should be dealt with in time to avoid oil leakage of hydraulic cylinder due to rust.
Hydraulic Oil And System Temperature.
During normal maintenance, it is necessary to pay attention to the regular replacement of the hydraulic oil, and the timely cleaning of the system filter to ensure the cleanliness of the hydraulic oil, which also plays a very important role in prolonging the service life of the hydraulic cylinder.
In normal work, pay attention to controlling the system temperature, because too high oil temperature will reduce the service life of the seals, and long-term high oil temperature will cause permanent deformation of the seals, and in severe cases, the seals will fail.
Trial Run Before Application And Cautions After Work Completed.
Each time we use the hdyraulic cylinder, it is necessary to perform a trial run of full extension and full contraction for 3 to 5 strokes before working. The purpose of this is to exhaust the air in the system and preheat the systems, so as to effectively avoid the presence of air or water in the system, causing gas explosions in the cylinder body, which will damage the seals and cause leakage in the cylinder, etc.
After work is completed, we need to pay attention to keeping the large and small arms and buckets in an optimal state, that is, to ensure that all the hydraulic oil in the hydraulic oil cylinder is returned to the hydraulic oil tank to ensure that the hydraulic oil cylinder is not under pressure. Because the hydraulic cylinder bears pressure in one direction for a long time will also cause damage to the seal.
