(Ghana pile driver hydraulic cylinder,produced by Hebei Hengyu company）

pile driver hydraulic cylinder are widely used in Ghana，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed pile driver hydraulic cylinder for customers from Ghana.

Introduction to pile driver hydraulic cylinder:

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.

Regular maintenance of the pile driver hydraulic cylinder includes: regular tightening, pile driver hydraulic cylinder fastening screws and gland screws, pile driver hydraulic cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the pile driver hydraulic cylinder once a year. Clean regularly, the pile driver hydraulic cylinder is cleaned every other year, and the seals are replaced while cleaning.

If the pile driver hydraulic cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the pile driver hydraulic cylinder. The internal parts of the pile driver hydraulic cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, and the action resistance is too large, so that the piston speed of the pile driver hydraulic cylinder changes with the different stroke position, and there is slip or crawl. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the pile driver hydraulic cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings. At the same time, check whether the lubrication is good or whether the pile driver hydraulic cylinder bore processing is out of whack. Because the piston and pile driver hydraulic cylinder, guide rail and piston rod are relative If the pile driver hydraulic cylinder is crawling seriously, check whether air has entered the hydraulic system. Air compression or expansion can cause the piston to slip or crawl. The exclusion measures are to check the hydraulic pump, set up a special exhaust device, and quickly operate the exhaust several times in the full stroke. Check the seals at the same time, because the quality of the seals is directly related to slippage or crawling. When the O-ring is used under low pressure, compared with the U-ring, it is easy to slip or crawl because of the higher surface pressure and the larger difference between static and static friction resistance. The surface pressure of the U-shaped sealing ring increases with the increase of pressure, although the sealing effect is correspondingly improved, but the difference between static and static friction resistance is also larger, the internal pressure increases, affecting the rubber elasticity, due to the increase in the contact resistance of the lip, the sealing ring will tip over and the lip elongation, and it is also easy to cause slip or crawling pile driver hydraulic cylinder weight composition and calculation. The weight of the pile driver hydraulic cylinder is composed of the pile driver hydraulic cylinder diameter, the outer diameter and weight of the pile driver hydraulic cylinder, the rod diameter, and the weight of the accessories, so in calculation, it is to add all these together to get the specific value. However, if there are special circumstances, it may be calculated separately. This work can be carried out by yourself, but it can also be carried out by professionals, so that mistakes can be avoided.

The scar on the sliding surface of the pile driver hydraulic cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the pile driver hydraulic cylinder wall. Therefore, before installation, these scars must be fully repaired.

Answers to some questions about pile driver hydraulic cylinder:

Structural characteristics of the plunger cylinder? (1) The plunger hydraulic cylinder is a single-acting hydraulic cylinder, which can only move in one direction by hydraulic pressure, and the return trip of the plunger depends on other external forces or the weight of the plunger; (2) The plunger is only supported by the cylinder liner and is not in contact with the cylinder liner, so the cylinder liner is easy to process, so it is suitable for long stroke hydraulic cylinder; (3) the total pressure of the plunger during work, so it must have sufficient stiffness; (4) The weight of the plunger is often large, and it is easy to sag due to its own weight when placed horizontally, resulting in wear of the seals and guide side, so its vertical use is more favorable.

How to refuel pneumatic riveting cylinder?
First put the gun flat, that is, horizontally, while pushing the stroke positioning pin and loosen the back cover, rotate to the left for a maximum of five turns, and then use a wrench to loosen the oil sealing screw, slowly add the hydraulic oil and let the air out, fill up to tighten the oil sealing screw. This process of adding hydraulic oil is over.
