DEFINITION

The multi-line system consists of

several pump elements that are

installed in one common housing.

From each individual element,

lubricant is supplied to one single

friction point.


DEFINITION

The progressive system may

consist of the same pump as

single-line or multi-line systems,

however, one pump element, via

a progressive metering device, is

capable of supplying several

friction points with lubricant.


System Description

Central lubrication with progressive distributors always consists

of the following basic elements:

Hand-operated, electric or pneumatically controlled lubrication devices (pumps)

Sectional or block progressive distributors

Distributing piping, plastic and metal tubes

Accessories, i.e. connectors, connections, clamps

The circuits of the central lubrication can also be furnished with

the following components:

Quick-break or contactless (induction) switch to signal the course of the lubricating cycle

Control and checking equipment (run timer)

Cleaning filters of distributing piping systems

Flow meters (for oil lubrication)

Pressure sensors


Functional Description

A central lubrication system with progressive distributors is built up in such a manner that the individual distributors are linked in series between the lubricating pump and lubricated points. The number of distributing piping systems progressively increases in the direction of the lubricated points. Lubricated points or other progressive distributors can be connected to the outlets of the individual distributors. The distributors provide the forced dosing of a pre-selected amount of lubricant according to the strokes of the individual pistons to the outlets, and then to the lubricated points. In the course of a lubricating cycle, all the pistons in all the distributors incorporated into the lubricating circuit are moved.

The system operates as long as the pump is in operation. If the pump is switched off, the progressive metering device remains in its current position. When the pump is switched on again, the metering device continues to operate from the point where it was interrupted.


Control and monitoring

The course of the lubricating cycle, i.e. the unit supply of lubricant to all the lubricated points, can be checked with a single signalling switch installed on one of the progressive distributors. The switch is usually placed on the control distributor or on the section of distributors that ensures the lubrication of the most important lubricated point. Generally, a switch can be placed on one or more of the progressive distributors in the lubrication circuit.

In the case where a control device fitted with a time delay relay is used, the period of the lubrication pump operation, during which one or several lubricating cycles take place, and the pause period, during which the lubrication system is out of operation, are fixed.


General technical data

A central lubrication system with progressive distributors makes use of an operating pressure between 30 and 250 bar depending on the types of lubricating devices applied. The main pipework between the lubrication pump and the control distributor (master) usually consists of 10, 8, and 6 mm outside diameter tubes. Branch pipework, between the progressive distributors, and the lines between the distributors and the lubricated points use 8, 6 and 4 mm outside diameter tubes.

Lubricants used may be any mineral oil. Bio-degradable oils must be approved by the manufacturer. Plastic lubricants or greases up to NLGI - 2 classification by DIN 51818 may be used.

DEFINITION

The two-line system consists of heavy pump element that

are installed in common housing. The devices are operated

by two main lines. As the system cycles, it alternately

pressurizes or relieves the flow of lubrication from one line to

the other. With each cycle, lubricant is dispensed to one half

of the lubrication points.

Accessories, i.e. connectors, connections, clamps

The circuits of the two-line lubrication can also be furnished with

the following components:

3/10/2014 Two - line 29

Control and monitoring By the use of DD distributors all the lubricated points are lubricated during one

lubrication cycle, this means that each lubricated point is lubricated from one

distribution circuit. If a control device fitted with a time delay relay is used, the

period of the lubrication pump operation, during which one or several

lubricating cycles take place, and the pause period, during which the

lubrication system is out of operation, are fixed. Pressure control of the

individual lubrication cycles can be achieved by engaging the terminal switch.

3/10/2014 Two - line 30


Dual - line central lubrication makes use of a working pressure of between

50 and 350 bar, according to the type of lubricating apparatus used. Pipes

with an outside diameter of 35 mm and 28 mm (3/4") are used as

distribution piping, while pipes with an outside diameter of 10 mm are used

for the branch circuits. Any kind of mineral oil may be used as lubricant. In

most cases, however, plastic lubricants or greases are used, classified at up

to NLGI - 2 in accordance with DIN 51818.

Lubricants used may be any mineral oil. Bio-degradable oils must be

approved by the manufacturer. Plastic lubricants or greases up to NLGI - 2

classification by DIN 51818 may be used.

DEFINITION

The single line consists of pump element that is installed in

small hydraulic unit. The devices are operated by one main

lines. System is built up in such a manner that a single main

pipework is mounted between the outlet of the lubrication

pump and the lubricated points. Connected to this piping, in

parallel, are the dosing elements

that supply the prescribed amount

of lubricant to the lubricated

points

3/10/2014 Single - line 43


A single-line central lubrication system makes use of an operating pressure

between 10 and 75 bar depending on the type of metering valves installed,

while the relief pressure is approx. 1 bar. The main piping between the

lubrication pump and the metering valves is usually made of 8 and 6 mm

outside diameter tubes, while for branch lines make use of 6 and 4 mm.

The lubricant used may be mineral oil with a viscosity between 50 and 1000

cSt (mm2s-1). For the use of bio-degradable oils consult the supplier. Liquid

grease of NLGI - 000, 00 class acc. to DIN 51818 may also be used (after

consulting the supplier).

Advantages in the Technique

Manual Lubrication Automatic Progressive System

• Lubrication every two weeks with hand

grease gun.

• The bearings are loaded on one side if

they are lubricated while not in operation.

The lubrication film cannot be build up

evenly in the bearing.

• After a certain operation time the grease

is used up and the bearings begin to

wear. The grease collar is not renewed

continuously and therefore its protective

effect is diminished.

• Lube points may be forgotten. Foreign

particles may be pressed into the bearing

when the lubrication fittings are dirty,

leading to premature wearing.

• Time-controlled lubrication of the bearings.

The grease is supplied to the bearings in small

quantities several times each day.

• The lubrication is performed while the

machine or vehicle is in operation, even at a

very high back-pressure. The lubricating film

builds up evenly in the bearing.

• Since the lubricating film is renewed

regularly, the service life of the bearings is

increased and the wear minimized. Moreover,

a grease collar protects the bearings against

penetration of water and dirt.

• All connected lubrication points are lubed

regularly and in exact quantities. Upon request

the lubrication system can be electrically

monitored.

3/10/2014 Single - line 48

Environmental Advantages

Manual Lubrication

• Large quantities of grease are expelled

from the bearings during lubrication. In

most cases this grease is not removed

and not disposed of. The grease lumps

may land on the surrounding

environment.

Automatic Progressive System

• A protective grease collar forms on the

bearings when the grease is pumped in

small quantities. This grease collar

hardens and can be properly disposed of.

For truck applications, the grease is

disposed of with oil separators when the

truck is washed in the washing yard.

• The burden on the environment is

smaller since the lubricant is metered

exactly in accordance with the

requirement.
