large hydraulic cylinder are widely used in Spain,because of powerful torque,simple structure and reliable operation,smooth movement.So our company has designed large hydraulic cylinder for customers from Spain.

Introduction to large hydraulic cylinder:

The wear of the hard chromium plating layer of the large hydraulic cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular large hydraulic cylinder action. Troubleshooting method: Replace the rubber hose.

large hydraulic cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the large hydraulic cylinder head itself is the guide sleeve of the piston rod, the large hydraulic cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the large hydraulic cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

The large hydraulic cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure large hydraulic cylinder can use 20 steel pipe, and the high pressure large hydraulic cylinder can use 45 steel pipe.

Answers to some questions about large hydraulic cylinder:

How many kilograms can the 63 cylinder hold?
The force of the cylinder is related to the cylinder diameter and pressure. 63 cylinder diameter (cylinder inner circle diameter), 21MPA pressure, thrust 6 tons.

Why does excavator cylinder oil leak?
Under normal circumstances, the leakage of hydraulic cylinders is divided into internal leakage and external leakage. The external leakage is generally due to damage to the oil seal at the extended end of the piston rod and needs to be replaced. Internal leakage is generally because the oil seal on the piston is damaged, you can try to replace the oil seal here, if the replacement will also leak, then check whether there is damage to the inner wall of the cylinder.
