Why a Centralised Lube system a Must?

posted by Sunil Newatia on April 7th, 2021


Some of the reasons which make it difficult to lubricate manually every day are:

weather conditions: rainy, chilly weather can be daunting for operators
production needs: meeting project deadlines if given priority over maintenance.
safety issues: the operator has to climb over the machine

logistics: manual lubrication equipment are not always available

time consuming: Bucket & boom pins need to be lubricated in more than one position

• Diligence:
not all operators perform lubrication properly

Failure to grease every lubrication point, on every machine, every day, can negatively affect schedules, maintenance costs and “on time” performance.

Shortcomings of manual lubrication:

· not evenly distributed inside the bushings

· not completely purged

· Over greasing

A Centralised lubrication system (CLS
) helps eliminate these unplanned and unnecessary expenses. Centralised lubricating system lubricates multiple points on a machine from a centralised pump/control unit which is mounted in an easily accessible location.

The system dispenses small measured/required amounts of lubricant at frequent intervals while your machine is operating, maintaining a uniform supply of lubricant in the bearings at all times and a consistent lubricant seal to prevent dirt, moisture and contaminants from migrating into bearings and bushings.

Advantages of a Centralised lubrication system (CLS):

Time savings:
Greasing with a grease gun takes 20–30 mins/ day, during which time the machine is idle. While the CLS continues to lubricate even while the machine is operational.

Measured Lubrication:
no over or under greasing

Effective Lubrication:
greasing frequently in small quantities

Better Housekeeping:
no grease spillage and contamination of job site

Increases life of critical wear points:
Protects your investment

Less unplanned downtime:
Increases profits

Fewer repairs & replacement parts to stock:
Lowers operating cost

Reduces operator involvement:
Keeps them focused on their primary job

Insures safety:
No climbing over and under equipment to lubricate

Longer Machine Life:
Increases resale value of equipment

CLS Single line Lubrication System

1 The pump is activated automatically by an internal adjustable timer.

2 Lubricant flow starts and it is delivered to the primary divider through the main hose.

3 The primary progressive divider distributes lubricant in metering amounts to the secondary divider.

4 The secondary dividers proportions the grease and delivers exact metering amounts to the bearings, bushings and pins according to their specific needs through secondary hoses.

In a Dual Line Lubrication system, lubricant flows from the pump through a single supply line to multiple branches of injectors. The injectors operate simultaneously but are independent of each other. Each injector serves only one lubricant point and may be accurately adjusted to deliver the precise amount of lubricant required. The nature of a parallel type system is such that only main line pressure is monitored, so if any feed line or bearing is not taking lubricant, the remainder of the system will continue to function normally, but the lubricant starved bearing may be lost.

FAQ’s

1. Does the pump package include a high-pressure, inline, lubricant filter?

Cenlube system provides Filter element of 300 microns mandatorily. A filter of this thickness prevents contaminants that often causes system failure leading to costly component replacement and labour costs. Moreover, the grease in the storage tank is stored in a hermetically sealed unit and grease is introduced at the bottom of the storage unit through the filter element by means of grease gun.

2. Are the hose, tubing and tube fittings standard NPT thread?

Some system manufacturers use metric hose ends and tube fittings. Special adapters are required to adapt to NPT inlets. Usually, BSP threading is observed on the mining equipment.

3. Does the system include a pressure gauge?

Cenlube System provides Pressure gauge, Filter Element and micro processor based timer controller. The presence of a pressure gauge allows for visual monitoring of the system pressure during regular maintenance inspections.

4. Does the CLS system have the manual grease fittings at metering valves?

Manual grease fittings, injectors on metering devices are part of Cenlube systems. Having a manual grease fitting at every metering valve allows for easier trouble-shooting, servicing, priming and flushing of grease lines. Not having a manual grease fitting means lines have to be disconnected to perform many of these tasks, substantially increasing labour costs.
