How Do You Safely Remove a Damaged Hydraulic Cylinder?

 The hydraulic cylinder consists of a cylinder barrel and a piston rod

First things first, SAFETY. Take time to inspect the machine and study the area in which you need to work. Understand the hydraulic cylinder system you are working on to a level where you know without question if there is any stored energy present (accumulators, heavy load on cylinders, machine parked on a hill etc), any danger that could hurt yourself or any other person.

Ensure the machine you are working on is tagged out and isolated so others cannot come and start the machine while you are working on it.

Once you have the machine locked out and you are certain there is no stored energy left in the lines you will need to then remove both ends that fix the cylinder to the piece of hydraulic equipment. Handy Hint; Be sure to remove the hoses/pipe work and plug both the cylinder ports and the hoses/pipework first..



Be sure that there is no pressure in the cylinder. If the cylinder clevis pins are tight to move it could be due to the fact that the load is still acting on the cylinder. It can also mean your clevis pins are seized and could require engineering assistance to remove.

Removing a cylinder from a hydraulic system can be a messy job, ensure you contain any hydraulic oil spill that could occur. Plug and cap both the hydraulic hoses and/or pipework along with the ports on the cylinder to ensure no oil is spilt in transit.

Once both the piston rod end and base end hydraulic pins have been removed the cylinder can now be removed.

How to deal with the scratch on the surface of hydraulic cylinder barrel

Image
As we all know,In the process of using the  hydraulic cylinder , the hydraulic cylinder barrel will be damaged,it is common that there will be scratch on the surface of the  honed tube , some customers will ignore these scratches, this to us is not responsible for the cylinder, when a small scratches in the cylinder,we usually take some tips to deal with them. 1.First,  to clean up the oil on the surface of our hydraulic cylinder barrel, then we will use the grinder machine to the surface treatment of the scratched part of our cylinder, at this time we have to grind the surface of the cylinder wall out of swallowtail groove. Although we have cleaned our cylinder at the beginning, at this time we need to clean the cylinder barrel further. At this time, we use anhydrous ethanol to clean the surface of the scratch repair of honed cylinder barrel. 2. We usually use special  repairing adhesive  to solve the scratches on the surface of  hydraulic cylinder barrel ...

Heat Treatments Of Seamless Steel Tube

Image
Heat treatment of  seamless steel tubes  is a process to improve the properties of metal materials and their products. Depending on the use, the material and its workpiece are heated to the appropriate temperature, insulated, and then cooled in different ways to alter the internal structure to achieve the desired performance. Heat treatment of seamless steel tubes is generally divided into annealing, normalizing, quenching, tempering, failure, chemical heat treatment and vacuum heat treatment. By heat treatment, the efficiency or life of the steel can be improved, and in some cases, more expensive special materials can be used instead of cheaper ordinary metal materials. The basic heat treatment methods of seamless steel tubes mainly include the following four forms: 1. Annealing Annealing is a process in which a seamless steel tube is heated to a slightly higher or lower critical temperature for a period of time (ie, heat preservation) and then slowly cooled. Common annealing...

HOW TO REPAIR THE HYDRAULIC CYLINDER ROD

  Hydraulic cylinders can be repaired, but you should never attempt these repairs on your own. Although hydraulic cylinders have a simple design, you must be familiar with them in order to efficiently repair them. When a technician performs hydraulic cylinder repairs, they take the entire mechanism apart and reassemble to find the root cause of the issue. COMMON POINTS OF HYDRAULIC CYLINDER FAILURE There are several common points of hydraulic cylinder failure. These include the piston, cylinder rod , seals, and head. PISTON The pistons in hydraulic cylinders are one of the most common points of failure. This is especially true in light-duty applications. The pistons used in light-duty applications are often made from aluminum, which wears out much more quickly than the steel used in heavy-duty applications. When checking pistons for failure, technicians will often measure the diameter of the piston. The piston’s diameter in relation to the bore directly affects the amount of hydra...
