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

Hans Jensen Lubricators A/S has following cylinder lubricators in their product program:

HJ Mechanical Cylinder Lubricator

The design concept of HJ Mechanical Cylinder Lubricators has proved to be stable and reliable and therefore the principle still applies today. The design, however, has been continuously improved to meet the customers’ increasing demands. Today, it is possible to configure the product based on requirements to include features such as safety valves, automatic joint quantity adjustment, suveillance alarms and MEP regulation.

HJ Lubtronic

HJ Lubtronic is a new hydraulic cylinder lubrication system, which by means of electronic control offers new possibilities within operation and working.  The HJ Lubtronic system is based on an electronically controlled cylinder lubricator for each cylinder. Each cylinder lubricator is operated by a computer receiving information on the engine’s load and similar. In this way, the customer can fully control and survey each individual cylinder lubricator. The regulation can be defined based on known algorithms such as MEP and BHP, but the customer can also define his own algorithms. This offers good possibilities for optimising the cylinder lubrication and reducing the cylinder lube oil consumption.

HJ Synchro Drive

In recent years, several engine builders have commenced constructing engines without mechanical drive. Hans Jensen Lubricators A/S has developed the HJ Synchro Drive in order to meet this development. The HJ Synchro Drive enables cylinder lubrication with mechanical cylinder lubricators without applying a mechanical connection to the engine’s drive. Instead, an electronically controlled electric motor is applied, operating the mechanical cylinder lubricators synchronously with the engine.

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.

On this page you can find replies to a series of questions, which we are frequently asked regarding HJ Cylinder Lubricators. If you find the replies incomplete, you are welcome to contact us with a description of your question or problem. We shall then try to help you best possible.

  • 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.
