Hydraulic Lubrication System
Lube-Power, Inc.’s Hydraulic lubrication systems can be found today in a wide variety of applications, from small manufacturing companies to integrated industrial applications.
The Hydraulic Principles used in our equipment enable the system to accomplish significant work with a minimum investment in mechanical linkage through the application of Pascal’s law. This principle is realized in a hydraulic system by the hydraulic fluid that is used to transmit the energy from one point to another. Because the hydraulic fluid is nearly incompressible, it transmits power instantaneously.
“Pressure applied to a confined fluid at any point is transmitted undiminished throughout the fluid in all directions and acts upon every part of the confining vessel at right angles to its interior surfaces and equally upon equal areas.” -Pascal’s Law
How Hydraulic Lubrication Systems Work
Each rotating equipment component has a flow restriction method to meter-in the correct amount of oil for that lubricated bearing. The bearing oil outlets are then combined and returned to the lube oil system. Contamination and excess heat are removed while the oil is circulating by using a heat exchanger. A correctly engineered and fabricated system keeps the rotating equipment operating properly without unscheduled downtime. Lube-Power, Inc. has pre-engineered systems for customers that do not have additional requirements. We also modify a standard system or start with a custom engineered solution depending upon the customer requirements at no additional cost. Our experienced staff routinely reviews customer specifications and we work through simple to complex applications while educating the customer when needed as part of our engineered solutions service. This product is very customizable to suit your specific needs. Each system typically includes these major components. Many additional details, options, and features are available for each item but not mentioned here. Contact Lube-Power, Inc. for more information.
Mounting Method: A baseplate, frame or drip pan is used when required by the customer or as when a mounting platform is a need for system components. They are normally constructed of the carbon steel plate and structural shapes. Smaller systems normally do not require a baseplate, frame or drip pan as components can be oil reservoir mounted.
Reservoir: This is also commonly called the tank, sump or vessel. It can be separate or integral to a piece of rotating equipment. The volume needs to be sufficient for all system functions including shutdown when all fluid is returned. We have seen customers with operational difficulties due to competitors who undersize the reservoir. Lube-Power, Inc. correctly sizes the reservoir by considering the lubricated equipment, mounting arrangement, system equipment, de-aeration, and particulate settling requirements.
Pump & Driver: A gear or screw pump is normally driven by an electric motor to circulate the required volume of fluid from the oil system to the lubricated equipment and then back to the oil reservoir.
Filter: A replaceable cartridge type filter is normally used to remove particulate contamination and extend rotating equipment bearing life. The filter cartridge traps particulate that is larger than the clearance range of the rotating equipment requirements. Single or duplex filter arrangements are provided. Single filters are provided when the equipment can be shut down for maintenance. Duplex (dual) filters are provided when the equipment cannot be shut down for filter changes. Automatic filter by-pass methods should be avoided.
Heat Exchanger: The heat exchanger removes heat generated from the rotating equipment process conditions. This keeps the fluid in the correct temperature range to avoid oil breakdown and extend rotating equipment bearing life. Normally either air to oil or water to the oil heat exchanger is used.
Piping & Valves: Pipe, valves, and fittings are used as a conduit for the fluid throughout the oil system and rotating equipment circuit. These items must be properly selected to minimize restrictions and avoid leaks. Special valves are also included to control system pressure and temperature to maintain optimum conditions.
Instruments: Pressure and temperature monitoring gauges, switches or transmitters are used to evaluate the oil system performance.
