HJ Lubricators

Background

The basic purpose of the HJ Cylinder Lubricators is to supply cylinder lube oil to the cylinders in order to reduce wear and corrosion of the pistons and the cylinders. Without cylinder lubrication, the cylinder liners and the piston rings will wear out quickly and the operation conditions of the engine will therefore deteriorate rapidly.

Functionality

HJ Cylinder Lubricators have been applied worldwide for close to a hundred years and are acknowledged for their reliable and solid design. In recent years, we have been working on expanding the product program HJ Cylinder Lubricators to also include electronically controlled cylinder lubricators. Hereby, new possibilities within operation and working of cylinder lubrication arise without compromising the operational reliability.

Customer specific solutions

Our product program is to a great extent based on our customers’ requirements. We give our customers the possibility of having their individual requirements fulfilled by offering them a wide product program and the possibility of selecting or deselecting various features.

You are welcome to contact us for further information on HJ Cylinder Lubricators.

Purpose

The basic purpose of the HJ Cylinder Lubricators is to supply cylinder lube oil to the valves placed in the cylinder. The primary purposes of the cylinder lube oil are to:

  • Reduce the friction between the cylinder wall and the piston rings
  • Neutralise the formation of acid in order to avoid corrosion
  • Ensure sealing between the cylinder wall and the piston rings in order to optimise the combustion pressure
  • Keep the cylinders and pistons clean by removing particles from wear and combustion

Regular maintenance is necessary for products of this type. We have therefore incorporated maintenance in our products right from the design phase. The products are optimised to have long intervals between overhauls. Furthermore, the products are optimised so that maintenance can be carried out quickly and effectively. The time between overhauls and the overhaul procedures are included in the manual for the individual products.

You are welcome to contact us for further information on maintenance of HJ Cylinder Lubricators.

  • Why shall I apply HJ Cylinder Lubricators?
    • The primary purpose of the HJ Cylinder Lubricators is to supply cylinder oil to the cylinders in order to reduce wear and corrosion of pistons and cylinders. Without cylinder lubrication,  the cylinder liners and piston rings will wear down quickly and the conditions of the engine will therefore deteriorate rapidly.

  • Which HJ Cylinder Lubricator shall I choose?
    • This is an individual evaluation based on requirement, engine configuration and economy. Each individual cylinder lubrication system has its advantages:

      • HJ Mechanical Cylinder Lubricators are easy to retrofit
      • HJ Lubtronic offers good regulation possibilities
      • HJ Synchro Drive permits application of mechanical cylinder lubricators without mechanical drive

      We are of course always at your disposal for advice regarding choice and configuration of HJ Cylinder Lubricators.
