DESIGN OF SYSTEMS
Bijur Delimon has recognized that the reliability and efficiency of a successful Oil Recirculation System requires it to fulfill the following key functions:
Supplying the appropriate quantity of lubricant of the required viscosity, temperature and pressure to a bearing or gear train to prevent failure.
By maintaining the system oil temperature and flow rate at the required parameters, the heat generated by the motion and load of bearings and gear trains is removed, ensuring that lubrication is provided at the optimum performance level.
It is critical to remove contaminants, such as dust, wear particles, water, and other extraneous materials that build up during the operation of bearings and gear trains. The lubricant needs to be continually filtered to the correct cleanliness level prior to being recirculated.
Bijur Delimon Design and Support Teams work closely with customers, component suppliers and lubricant manufacturers to ensure our Oil Recirculation Systems achieve the system performance levels required.

Standard Product Offering
One electric gear pump draws oil from a reservoir and supplies the oil via check valves through a single or dual basket type filter to the delivery connection.
Standard Units Comprised of:
MADE TO ORDER SYSTEM DESIGN
In providing the key functions of an Oil Recirculation System, the system is built from primary equipment, as outlined below.
RESERVOIRS OR TANKS
To allow for settlement, de-aeration and heating with the ability to facilitate a change of lubricant at the appropriate interval. Tank materials are typically carbon steel or stainless steel, and sized based on system flow rate and application.
Normally gear or screw type, motor driven to ensure the correct amount of lubricant is delivered to the friction points. In some cases, standby pumps are provided as part of the integrated design. These can be electrical or shaft driven, dependent on the application.
HEATERS & COOLERS
To ensure the lubricant reaches the points of application at the required viscosity. The heaters can be tank mounted or inline electric. The coolers can be plate type or shell and tube with the medium being water or water/glycol. Air can also be utilized for cooling using a fan and radiator.
FILTRATION & STRAINING EQUIPMENT
To maintain the system cleanliness. Typical oil filters will be either simplex or duplex type in the delivery line, suction line strainers, return line strainers, and tank breather/filters.
JACKING OIL PANELS
Jacking Oil Panels produce a small flow rate of oil at high pressure to lift the shaft of a bearing before it starts to rotate. Typical applications are large generators, cement kilns and ball mills.
In addition to the main primary equipment, a number of optional system components can be included, depending on the customer specifications and technical requirements.
RESERVOIR LEVEL MONITORING
Visual indicators, electrical switches and/or transmitters to alert the operator of low or high oil level, and protect the pump and tank immersion heater(s) from operating when the oil level is too low.
Visual gauges, electrical switches and/or transmitters to alert the operator of low or high pressures in the oil system delivery circuit, and similar pressure differential instruments to monitor the pressure drop across the main supply filter.
Visual gauges, electrical switches and/or transmitters to monitor the reservoir and delivery line oil temperatures.
Visual indicators, electrical switches and/or transmitters to monitor the oil flow to the friction point(s), oil return to the reservoir and cooling water supply. To support this, Bijur Delimon has developed the DS405 Lubrication Monitor; a highly configurable product that can be used on Oil Recirculation Systems and Total Loss Oil or Grease Systems respectively. Oil Recirculation Systems are real-time monitoring of the flow rate of oil, typicaly through an oval gear flowmeter. Alternative vane or spring operated flow meters are available.
Pump relief valves to protect the pump against excessive back pressure, system pressure control valves to control the flow and pressure of the lubricant to the friction point(s), and temperature control valve to either modulate the water flow to the water/oil cooler or by-pass the cooler when fitting in the oil supply line when the oil does not require cooling.
ISOLATION VALVES / CHECK VALVES
To isolate the oil or water supply, and prevent the oil from returning to the reservoir.
AIR PRESSURE VESSELS
Used in large systems to ensure sufficient pressure exists in the system to provide lubrication to all application points during operation and run down of the parent machine in the event of a power cut.
RUN DOWN TANKS
To provide lubrication to all application points during run down of the parent machine in the event of a power cut.
RUN DOWN PUMP
Pump operating from DC voltages can be employed during run down.
ELECTRICAL CONTROL PANEL ASSEMBLY
Our electrical engineering team are able to provide bespoke solutions for electrical. Design service from power supply to control panel and beyond. As standard, and if required, our systems are pre-wired at the factory.
SERVICES & SPARES
Maintaining Systems Throughout Their Lifetime
Bijur Delimon, either on a fixed contract or call-out basis, can maintain systems throughout their lifetime.
Our Service Department also operates contracts to provide labor to maintain plant in their client's works including system repairs, filling automatic grease systems, manual grease systems, manual greasing, and checking/filling oil reservoirs, gearboxes, etc.
