WHY LUBRICATION?
The parts in relative, rotary or linear motion, making up any industrial machine, are producers of friction. The purpose of lubrication is to reduce the friction and consequently the wear of moving parts, significantly decreasing the generation of heat, improving the performance of the machine, and increasing its service life. Lubrication of the moving parts can be obtained by procedures that differ in methodologies, for effectiveness and efficiency.
WHY CENTRALIZED LUBRICATION SYSTEM REQUIRED?
Is centralized Lubrication system required?
The centralized lubrication systems are designed for the automatic lubrication of moving parts that generate friction.
These systems considerably reduce maintenance costs for the machinery on which they are installed, eliminating machine downtimes for lubrication and extending the life of the lubricated components.
The automated systems also allow all the points requiring lubrication to be reached; even those not easily reached by an operator.
BENEFITS
■ Improves the efficiency of the machine, increasing its productivity
■ Lengthens the average service life of machinery
■ Avoids costly downtimes for insufficient or no lubrication, thus also reducing the costs of repair and spare parts
■ Correct dosing avoids unnecessary waste of lubricant, minimising costs and reducing the risk of environmental impact
■ Allows hard to access areas to be reached, thereby avoiding potentially dangerous situations for the operator
SINGLE LINE PROGRESSIVE SYSTEM
It consists of an independent pumping unit that feeds the volumetric distributors equipped with several outlets. The dispensing of lubricant, in a predetermined quantity, occurs through a progressive sequence.
SINGLE LINE PARALLEL SYSTEM
It consists of an independent pumping unit which, through a main line, delivers the lubricant (oil or grease) in a predetermined quantity to direct response volumetric dosers (injectors). These volumetric dosing units operate in two phases: in the first phase the pressurization of the system allows dispensing of the loaded lubricant.
Whereas doser loading (decompression) occurs in the second phase, when the system is not under pressure, Each injector to deliver predetermined quantities of lubricant.
DUAL LINE LUBRICATION SYSTEM
The centralized dual-line lubrication systems are normally used in large plants and machines: steel mills, cement works, mines, overhead cranes, shipyard cranes and presses.
The systems are sized in order to be able to reach rather high pressures from 200 to 400 bar. In such systems the length of the piping can easily exceed 100 metres
MULTILINE LUBRICATION SYSTEM
It consists of a central pumping station allowing the lubrication of a high number of users (up to 15) with oil or grease in predetermined quantities.
The pumping unit consists of an electric pump fitted radially with a number of pumping elements which, through the movement of a cam, push the lubricant in succession to the various deliveries, connected to the pipes.
SPRAY LUBRICATION SYSTEM
The lubricant transported by the pump is conveyed along a line to a nozzle. The lubricant mixes with the supply of compressed air in the nozzle. Depending on the application, the lubricant is then either sprayed intermittently, continuously or in a defined quantity. Different spray patterns and widths of spray can be generated, with the width of the spray and also the distribution of the lubricant depending on the medium, air pressure, temperature and air throttle setting. The volume of lubricant needed can be significantly reduced by a good distribution when spraying the lubricant.
AIR OIL LUBRICATION SYSTEM
Oil-air systems with a continuous lubricant supply consist of a pump that pumps the lubricant to the oil metering system. There is also an air throttle, which reduces the amount of air supplied. The oil metering unit and air throttle are connected to the so-called mixing chamber, which opens into the oil-air line.
The originally pulse-like droplets from the oil metering unit are drawn in this line with the aid of the air pressure in the line to form a long streak of oil. This makes it possible to pump micro-volumes of oil to the lubrication point and avoid undesirable oil mist. The streaks of oil can be monitored by streak sensors just upstream of he lubrication point. These monitoring sensors also enable it to be determined whether the line has a leak or whether the lubrication points are being reliably supplied with lubricant. The transport air stream in the line firstly cools the lubrication point and the overpressure of the air also provides protection from the bearing becoming contaminated. This system is often also referred to as minimum volume lubrication.
OIL CIRCULATION SYSTEM
Oil Circulation systems are primarily to lubricate and carry away the heat from bearings in most of the size.
As an added advantage other than cooling and lubrication, circulating oil flushes bearings and gearboxes which will remove contaminants.
Oil circulation systems are with a wide range of customized solutions for flow rates up to 3000 l/min and customized requirements for higher flow.
System integration will ensure accurate and reliable oil flow to all the lubrication point. Design of these systems are simple and easy to service. These systems can be scaled up easily within the operating limit.
Our Oil reservoir design will increase operating efficiency and effectively removes air and suspended water from the oil. This will prevent early deterioration of the oil and any other damage.
Valves provided in each line can be used for adjusting oil supply to the lubrication points. Monitoring of these visually and electrically are an added features for a fully digitalized and signal exchange with the control system to have more proactive approach for maintenance.
