For all of the commitment of a mine’s service team to the really helpful greatest follow in pump administration, someday, encountering instances of pump part wear and tear is inevitable – a matter of when and never if. And when it does happen, component put on inhibits pump efficiency. เกจวัดแก๊สlpg is at that time where, timeously, mines might have to seriously consider retrofitting as a possible option.
A rational enterprise decision
In this surroundings, the place prices of capital gear costs are increasing, replacement could additionally be a sensible business decision. In an advisory focused at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational enterprise decision: “Retrofitting is a wonderful various to purchasing a new product and could be performed on pumps no matter their intended use. It is equally suitable for industrial, water provide and waste water disposal functions as nicely as for the ability supply trade.”
It is just natural for mine operators to ponder buying new pumps. New pump fashions meet modern necessities like improved power effectivity, compliance with new legal necessities (relating to emissions and safety), prolonged service life and know-how which produces working knowledge. But this will likely not necessitate replacing an old pump mannequin, KSB Pumps says, as retrofitting may give an previous pump a new lease of life, specifically in the following ways:
Save maintenance costs
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 beyond modifications to the materials.
Hydraulic modifications
Some of the hydraulic modifications may contain:
Remachining of present impellers
Installation of recent impellers for off-design circumstances
Optimisation of volute casing for off-design conditions
Adjustment of the variety of levels (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 wear rings to enhance effectivity, rotor dynamics and dry working properties
Use of optimised materials
The following are its a variety of the supplies that a few of the optimised supplies that could 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, highly abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
