(Uruguay pile driver hydraulic cylinder,produced by Hengyu Group）

pile driver hydraulic cylinder are widely used in Uruguay，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed pile driver hydraulic cylinder for customers from Uruguay.

Introduction to pile driver hydraulic cylinder:

Repair method of small range wear of oil pile driver hydraulic cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

When installing the pile driver hydraulic cylinder, the axial ends of the pile driver hydraulic cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the pile driver hydraulic cylinder, there is axial expansion. If the two ends of the pile driver hydraulic cylinder are fixed, all parts of the pile driver hydraulic cylinder will be deformed. When disassembling the pile driver hydraulic cylinder, it is strictly forbidden to hammer the pile driver hydraulic cylinder and the piston surface, such as the pile driver hydraulic cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

The pile driver hydraulic cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the pile driver hydraulic cylinder should pay attention to: the operation should be as far away from the pile driver hydraulic cylinder as possible, to avoid falling objects, knocking, rubbing the pile driver hydraulic cylinder coating. When cleaning the pile driver hydraulic cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the pile driver hydraulic cylinder when the oil temperature exceeds 70 ° C.

When installing the pile driver hydraulic cylinder pipe, the pipe should be cleaned after installation, and should not pass through the pile driver hydraulic cylinder block, and the by-pass pipe must be installed in front of the oil port of the pile driver hydraulic cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the pile driver hydraulic cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the pile driver hydraulic cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

Answers to some questions about pile driver hydraulic cylinder:

How to remove the air in hydraulic cylinder?
Connected the cylinder to the system, and reciprocating move with full stroke several times, then the air can be eliminated . There is also a clunky method as follows: first remove the rod cavity oil pipe, connect the rodless cavity oil circuit to extend all the cylinders, and then remove the rodless cavity oil pipe, connect the rod cavity oil pipe and withdraw all the cylinders, and then connect the rodless cavity oil pipe, so that there is no air in the cylinder.

What is hydraulic cylinder internal leakage and external leakage?
The internal leakage of the hydraulic cylinder refers to the leakage of the piston head seal of the double-acting cylinder, and the leakage occurs inside the cylinder; The external leakage refers to the leakage phenomenon between the cylinder head (or cylinder guide sleeve) and the plunger rod (or piston rod) and the seal between the guide sleeve and the cylinder block, and the oil in the hydraulic cylinder leaks to the outside.
