Recirculating lubrication system maintenance

Oil re-circulation involves a continuous oil flow to the lubrication points. This oil is controlled both in quantity and temperature, it is collected by drains piping and returned to a supply tank. The oil is therefore "re-circulated" back to the point. When the oil flows through the lubrication point it does not only act as a lubrication agent but also removes a large amount of heat from the bearing or lubrication area. The oil is the transported away and back to the lubrication tank.

Oil re-circulation is used extensively in the power industry and pulp and paper industry allowing for increases in operating speed and performance thanks to the fast change-over of lubricant that removes heat and provides full-oil immersion lubrication.

Oil recirculation systems are often singular and specifically engineered for a particular application. Therefore having a partner that can assist in each phase of the project is important. Dropsa is beside the customer during all phases of development with the provision of the site survey, pump station design, manufacture, installation and turn-key implementation of oil re-circulation systems.

Dropsa has developed patented world leading technology to achieve this with remote diagnostics to ensure that the oil recirculation system is always operating at peak efficiency. DropsA worldwide DropsA S.To begin a discussion of preventive maintenance of any machine or component, one should first define preventive maintenance.

A suitable definition is this: maintenance that can be performed economically to prevent equipment breakdowns before they occur, shifting the greater portion of maintenance work to a planned basis. Emphasis is placed upon the word economically, as costs for elaborate and frequent preventive maintenance functions may exceed any savings resulting from the effort. Equipment relubrication is a preventive maintenance function. In many applications, applying lubricant is most effective when it is dispensed in small quantities at short time intervals.

Many operations and types of machinery do not permit this optimum approach to lubrication. Consequently, components are lubricated at intervals dictated by machine operations, available manpower and machine availability. For these reasons, centralized lubrication systems are often installed on existing machinery or on new machinery as it is manufactured. The basic purpose of a central system is to provide a controlled and reliable means to lubricate multiple bearing surfaces from a central location.

Two broad categories include:. Pumping station - delivers lubricant to the system at the proper flow and pressure.

Recirculating Oil Lubrication Systems

It may include flow and pressure controls, timers, filters, pressure gauges and over-pressure protection devices. Lubricant distribution systems - deliver lubricant from the pumping station to the metering valves and from metering valves to the lubrication point. Metering valves and fittings - provide controlled deliveries of lubricant to specific lubrication points by either a specifically sized piston discharge or by a specifically sized flow restrictive orifice.

These components are common to all systems whether they are positive displacement, parallel, series, multiline or combination, oil flow proportioning, single-line resistive or aerosol.

Once a proper lubricant is selected for machinery lubrication and the system is properly designed and installed, the natural tendency is to assume that the proper lubricant is applied at the proper time, in the proper place, and in the proper quantity.

This is a false assumption; the central lube system must be serviced regularly to operate at peak efficiency. In the development of a preventive maintenance program relating to any centralized lubrication systems, the major system components must be reviewed. Energy and pressure generating components a. Electric pumps b. Pneumatic pumps c. Hydraulic pumps d. Mechanical pumps e. Manually operated pumps.

Control components a. Timers b. Reversing valves c. Pressure regulators d.Low oil pressure is indicated when the oil indicator light glows, oil gauge reads low, or when the engine lifters or bearings rattle.

The most common causes of low oil pressure are as follows:. A low oil level is a common cause of low oil pressure.

Always check the oil level first when troubleshooting a low oil pressure problem. High oil pressure is seldom a problem. When it occurs, the oil pressure gauge will read high. The most frequent causes of high oil pressure are as follows:. A bad oil pressure indicator or gauge may scare the operator into believing there are major problems. The indicator light may stay on or flicker, pointing to a low oil pressure problem.

The gauge may read low or high, also indicating a lubrication system problem.

Inspect the indicator or gauge circuit for problems. The wire going to the sending unit may have fallen off.

The sending unit wire may also be shorted to ground light stays on or gauge always reads high. To check the action of the indicator or gauge, remove the wire from the sending unit. Touch it on a metal part of the engine. This should make the indicator light glow or the oil pressure gauge read maximum. If it does, the sending unit may be defective.

If it does not, then the circuit, indicator, or gauge may be faulty. There are certain lubricating system service jobs that are more or less done automatically when an engine is repaired. For example, the oil pan is removed and cleaned during such engine overhaul jobs as replacing bearing or rings. When the crankshaft is removed, it is usual procedure to clean out the oil passages in the crankshaft. Also, the oil passages in the cylinder block should be cleaned out as part of the overhaul.

As a Construction Mechanic, you will be required to maintain the lubrication system.

Oil Recirculation Lubrication

This maintenance normally consists of changing the oil and filter s. Occasionally you will be required to perform such maintenance tasks as replacing lines and fittings, servicing or replacing the oil pump and relief valveand flushing the system. The following discussion provides information that will aid you in carrying out these duties. It is extremely important that the oil and filter s of the engine are serviced regularly. Lack of oil and filter maintenance will greatly shorten engine service life.

Manufacturers give a maximum number of miles or hours a vehicle can be operated between oil changes. Newer automotive vehicles can be operated 5, miles between changes. Older automotive vehicles should have their oil changed about every 3, miles. Most construction equipment average between and hours of operation between oil changes.Each year millions of dollars are spent for new plant equipment designed to build things better and faster.

However, machines continue to break down. Each bearing failure directly impacts the production cycle. While bearings can be expensive, replacement cost alone is often miniscule compared to lost production and the cost to repair the damage. Why, in the age of technology, is this a problem? It is because many bearings are still lubricated manually.

No matter how diligently a maintenance staff adheres to a lubrication schedule, it is a difficult task. Every bearing, regardless of size or location, needs to be lubricated properly. Improper lubrication will result in high, yet unnecessary costs for the operation. Some of the direct costs resulting from improper lubrication include replacement bearings, labor for replacements and repair, excess lubricant and labor for inefficient manual practice. Some of the indirect, but very real costs are downtime or lost production; product spoilage due to excess lubricant; environmental, safety or housekeeping issues; and excess energy consumption.

While grease guns and manual lubrication seem to get the job done for many maintenance operations, their benefits often cannot compare to those provided by an automated lubrication system in terms of productivity, environmental issues and worker safety. An automated lubrication system helps to prevent bearing failure by providing the right amount of the right fresh, clean lubricant at the right time to the right place. The main difference between automated and manual lubrication is that in the case of manually applied lubricants, technicians tend to lubricate on schedule once a day, week, month, year, etc.

To compensate, the operator often will fill the bearing until he sees lubricant seeping out. This sets up an overlubrication and underlubrication scenario. Conversely, automated lubrication provides lubricant constantly at an appropriate amount that allows the bearing to operate at its optimum.

When the bearing is properly lubricated in this manner, it also helps to seal the bearing from contaminants. Maintaining proper lubrication on production equipment reduces the number of breakdowns due to bearing failure. In addition, there is less downtime due to the manual lubrication process, as well as substantially reduced man-hours required for the task.

Automated lubrication is more precise and eliminates the cycle of overlubrication and underlubrication that contributes to bearing failure Figure 1.

Figure 2. Manual Lube Safety. Even the most cautious maintenance personnel encounters difficult conditions when performing manual lubrication, especially when machinery is in operation. It also prevents excess lubricant from finding its way onto the finished product, the plant floor or other work surfaces. This results in fewer rejections, cleanup and disposal problems, as well as less waste of lubricant.

Another benefit of an automated lubrication system is worker safety. It becomes unnecessary for employees to engage in the potentially hazardous practice Figure 2 of manually applying lubricant while machinery is operating or in hazardous, difficult-to-reach locations.

When considering the benefits of implementing an automated lubrication system, it is important to know that it could pay for itself within the first year through the cost savings it generates. Production uptime, preventive maintenance costs, repair costs, safety expenses, environmental compliance costs, lubricant costs and machine replacement costs are all positively impacted. Depending on the application and size, each replacement bearing costs anywhere from a few dollars to several thousand dollars.

It takes approximately three hours for a worker to replace each bearing. We can calculate the average cost to replace each bearing in the following example:. There is no standard for the cost of a lubrication system. It becomes a fairly simple matter to justify the cost of an automated lubrication system.In the past, this covered engine oils with the viscosity 0W, 5W, 5W and 10W with fuel efficiency quality.
