C14 Total loss grease systems

CONSIDERATIONS IN STORING, PUMPING AND TRANSMITTING GREASE
AND GENERAL DESIGN OF SYSTEMS

Considerations

Storing grease TEMPERATURE at which grease can be pumped
CLEANLINESS of grease
PACKAGE sizes available. Ease of handling
RESERVOIRS : Exclusion of dirt; internal coating; positive pump prime; provision of strainer, follower plate
and scraper; pressure relief; level indicator; emptying and cleaning access; connections for remote feed

Pumping grease ACCESSIBILITY of pump for maintenance
CORRECT ALIGNMENT of pump and motor
COUPLING between pump and motor to be adequate size for horse power transmitted
MOUNTING to be rigid and secure
ACTUATING ROD (if any) to be free from deflection
NAME PLATE on pump to be clearly visible and kept clean
DIRECTION of rotation to be marked
~- -~
Transmitting grease PIPE SIZING : Pressure in lines; length ofruns; volumeoflubricants; number ofbends; temperature fluctuation
~~
Work conditions INGRESS of water, scale, dust
POSSIBLE DAMAGE to piping
ACCESS to piping in onerous locations

Human factors AVAILABILITY of labour
RELIABILITY of labour
Trade union practices

General design points CORRECT positioning of lubrication points
PRODUCTION requirements
QUALITY OF PIPING and materials- use only the best
AVOID splitting unrnetered grease lines
ENSURE that grease holes and grooves communicate directly with faces to be lubricated
