Pump retrofitting: New Lease of Life for Old Pumps

For เกจวัดแรงดูด of a mine’s service group to the really helpful greatest follow in pump management, sometime, encountering cases of pump element put on and tear is inevitable – a matter of when and not if. And when it does happen, component put on inhibits pump efficiency. It is at that time the place, timeously, mines could have to significantly think about retrofitting as a possible choice.
A rational enterprise choice
In this surroundings, where prices of capital equipment prices are rising, replacement may be a wise enterprise choice. In an advisory targeted at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business choice: “Retrofitting is a wonderful different to buying a brand new product and could be performed on pumps regardless of their supposed use. It is equally suitable for industrial, water supply and waste water disposal functions as properly as for the power provide business.”
It is only natural for mine operators to contemplate buying new pumps. New pump fashions meet modern requirements like improved vitality efficiency, compliance with new legal requirements (relating to emissions and safety), extended service life and expertise which produces operating data. But this will not necessitate replacing an outdated pump mannequin, KSB Pumps says, as retrofitting may give an previous pump a brand new lease of life, particularly within the following methods:
Save upkeep costs
Reduce power consumption
Achieve longer service life
Increase system availability
Comply with authorized necessities (e.g: TA-Luft, ATEX)
READ: Full-service capability very important for reliable pump provide
Core areas in Retrofitting
The core focus areas in retrofitting are: hydraulic and mechanical modifications to the supplies, above and past modifications to the supplies.
Hydraulic modifications
Some of the hydraulic modifications might involve:
Remachining of current impellers
Installation of new impellers for off-design situations
Optimisation of volute casing for off-design situations
Adjustment of the number of phases (on multistage pumps)
Mechanical adjustments
The following are a variety of the mechanical changes:
Closed bearing brackets enhance the smoothness of operation and extend the bearing life
Installation of mechanical seal methods
Employment of cellular floor put on rings to improve effectivity, rotor dynamics and dry operating properties
Use of optimised materials
The following are its a number of the supplies that a number of the optimised supplies which might be used:
Super duplex stainless-steel grades or nickel alloys
Ceramic mineral castings for impellers, wear plates, cover and casing – to be used with finely dispersed, extremely abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
