central lubrication system and Lubrication for Industry

In just a few clicks we offer an overview for fields of application and applications for Vogel central lubricating units and central lubrication systems. We gladly assist you in compiling the perfect products for your individual needs. Central lubrication systems serve the purpose of providing bearing points in machines or vehicles with lubricant from a centralised source. Vogel central lubrication lowers your maintenance intervals, prolongs machine time and reduces personall expenditures.

Vogel central lubrication:

Central lubricating units for lubricating machines and machinery are divided into the following system options:

  • Single-line systems
  • Progressive systems
  • Chain lubrication systems
  • Multi-line systems

Single-line systems:

Single-line lubrication is often used in the following fields of application: Calender, mechanical engineering, apron conveyors, bottle cleaning machinery, presses, packaging machines, tire heating, machine tools, brickworks machinery, etc.

These single-line systems are suitable for over 100 lubricating points. However, a total line length of 30 meters and a pump pressure of 160 bar should not be exceeded.

The central lubrication systems pump transports a lubricant (oil or semi-fluid grease) to the main line. The main line then branches separately or grouped to distributors near the lubricating point. These distributors meter the lubricant precisely (even with high counterpressure) in the line which leads directly to the wear point. During the lubrication cycle, the line is pressurized, which then distributes the dosed oil or semi-fluid grease to all lubricating points. Hereon the main line is discharged by connection to the pumps suction chamber. Here, the lubricant is rearranged inside the distributors.

Single-line central lubrication offers a lot of advantages:

  • Systems can be easily expanded with new distributors (or equally reduced) depending on requirements.
  • The dosing amount can be accurately matched to lubricating points by adjusting the allocation screw inside the distributor units according to the amount of lubricant needed.
  • The main line is relieved during lubrication intervals.
  • During lubrication intervals the excess lubricant gets shifted inside the distributors i.e. it gets transported from the pistons lower side to its upper side. Simultaneously this process effectuates that no lubricant is distributed to any lubricating point unregulated.
  • The amount of lubricant which the distributors dispense is widely independent of counter pressure.
  • Fully automatic operation in installations with engine-driven single-line pumps is possible. The only thing to be aware is the correct adjustment of idle periods.

Progressive systems:

Progressive systems can be used for installations with up to 100 lubricating points in which a progressive pump is combined with progressive distributors. These systems are also suitable for both oil and semi-fluid grease. The progressive pump transports the lubricant through the main line to the main distributor which distributes the medium into the remaining distributors and thereby to the points of lubrication. Progressive distributors are able to emit lubricant in very small, specified amounts progressively (advancing) and in distinct sequence through all individual outlets to connected wear points. As soon as the last wear point is supplied the lubrication system starts with the first position automatically. If an interruption occurs during the cycle, lubrication continues from this exact point upon restarting. These systems can be found in fields of application such as woodworking machinery, presses, stamps, packaging machinery, cropping, machine tools, etc.

Progressive systems offer the following advantages:

  • Minor investment consts (only one main line, one standard pressure pump and comparatively standard distributors are necessary).
  • If back pressure valves are installed, multiple lubrication groups can be switched on and off via progressive distributors.
  • Function control is easy with movement indicators on distributors or per remote control.
  • Distributors are relatively small in size.

Chain lubrication systems:

Chain lubrication system for semi-fluid grease/grease:

Apron conveyors and such are often equipped with handling devices and grease fittings. For this purpose, there are lubrication systems ensuring a continuous and automatic lubrication. Only a small amount of movable parts are used. Lubricating elements are controlled with rotary valves. These elements lubricate bolts on chain wheels during deviations.

Chain lubrication systems for oil:

We also offer central lubrication solutions for supplying chain lubricating points with small amounts of oil without the use of compressed air. The associated pumps are able to supply a chains lubricating points, up to 12. Multi-threaded systems allow the supply of a significantly higher amount of lubricating points. Their key benefit is the minimal amount of oil (0,01 cm³ / 0,025 cm³) required per lubricating point and lubrication cycle. These systems are often used in automotive industries.

Multi-line systems:

Multi-line central lubrication is primarely used for lubricating single machines and small machine or device clusters. The lubricant is dosed and metered via multiple small outlets on the pump. Every outlets line connects directly with the lubricating point. Because of the lubricating pumps type of construction the amount of lubricating points is limited to 32. Any further increase in wear points is only possible by using progressive distributors.

The maximal line length is dependent on multiple parameters:

  • Lubricant consistency and transportation capabilities
  • Lines cross section
  • Pump pressure
  • Flow volume
  • Operating temperature

Normally, the max. line length can be estimated to 20 to 40 meters. If the line is too long the pipes friction resistance increases, in case of doubt it can surpass the pumps superable pressure.

Multi-line systems are used for the following applications:
Woodworking machinery, presses, stamps, excavators, cranes, cropping, elevators, machine tools, conveying systems, packaging machines, compressors, stone crushers, construction vehicles, automotive industry and compactors.

A notable benefit of central lubrication is the possibility of powering the system via the machine that needs to be lubricated and thus eliminating the need of additional control systems. Dosing amounts are available individually for each lubricating point. Continuous operation leads to small amounts of lubricant.
