DUALINE LUBRICATION SYSTEMS

Farval® Dualine lubricating systems are found in virtually every industry in which continuous duty operation is required. From steel production to pulp and paper, from mining equipment to machine tools, automatic application of the lubricant provides significant benefits to the equipment user. There are several components that are used in designing a Dualine lubrication system, including valves, lubricators, reversing valves, central stations, controllers, and spray systems.

VALVES

Measuring valves are the heart of Farval® Dualine lubrication systems. They are mounted close to the lubrication points and are hydraulically operated by pressure from the first and then the second of the two supply lines. On each pressurization cycle, they indirectly discharge fixed volumes of lubricant to the bearing or lubrication point.

LUBRICATORS

Manual, electric and pneumatic lubricators store and pump lubricant to Dualine valves throughout the system.

REVERSING VALVES

These valves change the flow and direction of pressure, which causes divider valves in the system to cycle.

CENTRAL STATIONS

Central stations include lubricator, cycle switch and reversing valve. Some versions are mounted on a plate for easier installation.

CONTROLLERS

Programmable give you access to key system functions, such as system on and off, and can control what happens when there is a problem in the system.

SPRAY SYSTEMS

Used to lubricate large gears and pinion sets.

SINGLE LINE RESISTANCE (SLR) LUBRICATION SYSTEMS

The Original Developers of the Single Line Resistance System

Bijur Delimon single line resistance systems are low pressure oil lubrication systems that are designed for light or medium machinery requiring up to 100 points of lubrication. These systems are compact, economical and relatively simple to operate and maintain. Two types of systems (manual and automatic) are available to meet virtually any industrial application.

MANUAL SYSTEMS

Ideally suited for machinery which can be lubricated by a hand actuated, intermittently fed oil discharge system on an occasion basis.

AUTOMATIC SYSTEMS

Ideally suited for machinery requiring an uninterrupted discharge of oil either regularly timed or continuous. Automatic systems are actuated by a self-contained timing mechanism or by a mechanical drive mechanism connected to the equipment being lubricated.

ADVANTAGES

Single line resistance systems are compact, economical, and relatively simple to operate and maintain. The system is ideally suited for machinery or equipment which displays closely configured bearing clusters or groups. A precisely controlled discharge of oil is delivered to each point while the machine is in operation. The system provides a clean film of oil between critical bearing surfaces to keep friction and wear to a minimum. Machinery life is extended and production efficiency is maintained.

SYSTEM ELEMENTS

A Bijur Delimon SLR system is a highly reliable, low pressure oil lubrication system, which consists of three basic elements:

1. LUBRICATOR (PUMP) & RESERVOIR Bijur Delimon lubricators are either actuated manually or automatically. Manual lubricators are operated on demand by the machine operator. Automatic lubricators are designed to operate at predetermined, regular intervals. Typically, they're controlled by a timing mechanism or direct drive with the equipment.

2. RESISTANCE FITTINGS A resistance fitting is the part of the system that proportions and dispenses oil to a friction point. It must be remembered that the amount of oil delivered to each point in the system is apportioned by a resistance fitting, not the lubricator. The lubricator controls the volume of oil available for overall system consumption. Bijur Delimon offers ten different sized flow devices. Each one is designed for one-way delivery of a proportioned quantity of oil to a bearing or surface.

3. DISTRIBUTION NETWORK Tubing plus various junctions, adapters, clips, and connection hardware make up the distribution network. The network connects the lubricator and individual resistance fittings located at or near the friction points. Typically, a single line (5/32" O.D.) tube is branched at convenient locations to meet the requirements of the machine's bearing arrangement.

POSITIVE DISPLACEMENT INJECTOR SYSTEMS

Bijur Delimon positive displacement injector systems are for low or medium pressure oil or grease lubrication systems. These systems are precise in their lubrication delivery, and some models are adjustable, so a single injector manifold can be used to deliver different amounts of oil or grease to different friction points.

Injectors are alternately activated and deactivated at regular intervals. Oil and fluid grease discharges from the injectors when the system reaches operative pressure.

SINGLE POINT LUBRICATION SYSTEMS

Single-point lubricators are simple in design, but very effective at delivering grease or oil to your bearing lubrication point. By using different springs, users are able to estimate the time it will take to run the unit to empty. The on-demand technology makes it impossible to predict the exact date, but the clear reservoirs make it easy to visually assess the lubricant level at any time. Once the reservoir is filled and the unit is connected to a bearing, the single-point lubricator uses Venturi action to discharge lubricant only when the bearing is in motion. This benefits manufacturers that will have some planned machine downtime, because over-lubrication is eliminated. Because the single-point lubricator only generates 1-5 psi it will not blow bearing seals. Lubricant discharge is immediate when the vacuum is created from the bearing.

Environmentally-minded manufacturers will appreciate the refillable feature of these single-point lubricators, since the unit can remain mounted on a bearing, with just pennies of grease to top off the reservoir. And any grease can be used in these units, so grease used in other applications on the plant floor can be used.

PROGRESSIVE LUBRICATION SYSTEMS

Bijur Delimon International series progressive lubrication systems are generally used on medium-duty machinery and equipment. Robust pumps are connected to divider valves, some of which are modular, allowing for easy installation, modification and maintenance, without the removal of any tubing.

The series M2500G, 3000 and PVBM Progressive Divider Valve Manifolds distribute and proportion incoming oil or grease to bearing points. A typical divider valve manifold consists of an inlet section, three to ten valves, and an end section. One assembly can serve up to a maximum of 20 lubrication points. Individual divider valve blocks have a discharge piston and built-in outlet check valves. Blocks are offered in various output sizes. The discharge capacity of a block is determined by varying the piston diameter in the valve block.

Twin valve blocks have two outlets located at each end of the assembly and supply rated discharge from each of the two outlets during one complete valve cycle. Single outlet blocks have one end outlet plugged and supply twice the rated output to the open outlet. External cross porting of adjacent valves can be achieved with a cross port kit to combine outputs.

PROGRESSIVE DIVIDER VALVE OPERATING SEQUENCE

Individual valve blocks operate in a “Progressive” sequence. During operation, the piston within the block must complete a full discharge cycle before another piston begins operation. As long as lubricant is supplied under pressure to the inlet section of the divider, manifold valve blocks will continue to operate in a progressive manner.

When lubricant flow is interrupted to the inlet block, piston movement stops. When flow resumes, piston movement commences at the same point in the discharge cycle. Feed lines deliver lubricant from the valve block to individual lube points. Should a discharge line become blocked, it will stop all the valves operating. Indicators are available to alert a blockage.

GEAR SPRAY LUBRICATION SYSTEMS

Gear spray is popular in cement plants, mining, Iron Ore crushers, kilns, and any external gear drive usually with a dry sump. The gear spray lubricant is periodically sprayed onto the pinion drive gear, large ring or slew gear. The lubricants on older installations use asphalt-based lubricants with a thinner. Newer installations use synthetic gear lubricants. Gear replacement is a major cost, most cases it forces the plant to be down for days. Bijur Delimon's Gear Spray lubrication system and products can reduce friction improving uptime and prevent costly repairs.
