Production and repair of hydraulic cylinders

Hydraulic cylinders play an indispensable and fundamental role in the creation and functioning of modern machines. They are their “linear” actuator. The operation they perform is to move loads or mechanisms in/out or up/down.

There are also cylinders that can act as shock absorbers, hydraulic boosters in steering mechanisms and actuators, etc. Mainly oil and compressed air are used for propulsion, but there are special applications where the propulsion fluid can be solutions of water and others.

Hydraulic cylinders are used in all industries – automotive, machine building, shipbuilding, mining and many others, and our customers are even companies in the entertainment industry.

The main elements of hydraulic cylinders are:

– pipe                                      – hesd/ cap                   

– piston rod                            – piston                         

The main parameters used to define cylinders are:

– the function it performs

– working fluid and pressure

– pipe and piston rod diameter

– мminimum overall size and working stroke of the cylinder

All hydraulic cylinders received for repair are disassembled and their components are cleaned and inspected. The tube and piston rod are measured for straightness and wear. The packing channels are cleaned, after which packings are produced to the dimensions reached after the primary operations. If necessary, piston rods, pipes are replaced, new pistons and valves are made. In most cases, honing the tube is recommended to achieve maximum smoothness, which guarantees the longevity of the corresponding cylinder.

When you need hydraulic cylinder repair, it makes sense to rely on a company with experience in high-quality repairs, reliable service and efficient solutions.

The main advantages of HYDROMARK are the availability of modern machines for disassembly, assembly, testing, honing, turning, milling and welding.

All gaskets are made for the specific cylinder by selecting the most suitable profile with necessary sealing tolerances. For their production, we use high-quality materials developed and manufactured in Austria.

We are not dependent on supplies of materials or external services, which makes it possible to perform extremely high-quality services in the shortest possible time.

All repairs are tested on a hydraulic test bench, with which we guarantee the quality of the repair.

Horizontal honing of H8 pipes

Horizontal honing is a process in which a reciprocating motion simultaneously with the rotation of an abrasive head increases the size of a tube to an accurate size and smoothness.

HYDROMARK has one of the most modern machines, designed for a wide range of applications, sizes and lengths. Designed with a unique system that, by means of modern software, commands the movement, the feeding of the abrasive stones, automatically adjusts the effort to achieve the set dimensions and smoothness.

The minimum size for honing is 50 mm, and the maximum is 600 mm.

Pipe length up to 8000 mm.

The terms are minimal: from a few hours to a few days, depending on the request.

Whatever your job, from the repair of a defective hydraulic cylinder with a cracked pipe, to the production of pipes with non-standard dimensions and a precisely smooth surface, to components for aircraft construction, HYDROMARK guarantees a highly efficient and quality service in pipe honing, thanks to modern technology and quality materials with which it operates.

Production of details from ferrous and non-ferrous metals for hydraulics

Drilling holes with an oxygen spear

Oxygen lance drilling is a cutting process that uses oxygen passing through a steel tube. It is mainly used for drilling holes in metal and mineral parts.

Main applications of oxygen spear:

  • Cutting large metal castings
  • Cutting a mixture of materials – Combinations of metal and concrete are extremely difficult to cut because the techniques for metal are not compatible with those for concrete. Using an oxygen lance will easily cut both materials at the same time.
  • Drilling and cutting concrete
  • Knocking out pins, pins, plugs from metal

The temperature reached in the center of the combustion zone is approximately 4000 °C, higher than the melting point of any substance on earth. In comparison, concrete melts at 1800 – 2500 °C and steel at less than 1500 °C. Because it runs on oxygen, the spear can cut underwater.

Oxygen drilling can be used to drill almost all minerals and ferrous metals, anywhere. Mobile use and environmental benefits are decisive advantages over competitive processes.

We, HYDROMARK, have a team of professionals trained to work with oxygen lance, who are ready to visit your site on site. For information on how to work, contact us.
