Pump retrofitting: New Lease of Life for Old Pumps

For all of the commitment of a mine’s service group to the beneficial best apply in pump management, someday, encountering cases of pump element wear and tear is inevitable – a matter of when and not if. And when it does occur, component wear inhibits pump performance. It is at that point the place, timeously, mines may have to noticeably think about retrofitting as a feasible option.
A rational enterprise choice
In this setting, where costs of capital equipment costs are rising, replacement may be a sensible business decision. In an advisory targeted at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business choice: “Retrofitting is a superb various to buying a new product and could be performed on pumps regardless of their intended use. It is equally appropriate for industrial, water provide and waste water disposal applications in addition to for the power provide business.”
เกจวัดแรงดันถังออกซิเจน is only natural for mine operators to ponder acquiring 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 knowledge. But เกวัดแรงดันน้ำ may not necessitate replacing an old pump model, KSB Pumps says, as retrofitting might give an previous pump a brand new lease of life, particularly in the following methods:
Save upkeep prices
Reduce energy consumption
Achieve longer service life
Increase system availability
Comply with legal necessities (e.g: TA-Luft, ATEX)

Core areas in Retrofitting
The core focus areas in retrofitting are: hydraulic and mechanical modifications to the materials, above and past changes to the materials.
Hydraulic modifications
Some of the hydraulic modifications may involve:
Remachining of current impellers
Installation of recent impellers for off-design conditions
Optimisation of volute casing for off-design circumstances
Adjustment of the number of stages (on multistage pumps)
Mechanical changes
The following are a few of the mechanical changes:
Closed bearing brackets improve the smoothness of operation and lengthen the bearing life
Installation of mechanical seal methods
Employment of cellular surface put on rings to enhance effectivity, rotor dynamics and dry working properties
Use of optimised supplies
The following are its a variety of the supplies that a few of the optimised supplies which may be used:
Super duplex stainless-steel grades or nickel alloys
Ceramic mineral castings for impellers, put on plates, cover and casing – to be used with finely dispersed, highly abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
