For เกจวัดแรงดันแก๊สlpgรถยนต์ of the commitment of a mine’s service team to the really helpful finest follow in pump management, sometime, encountering instances of pump component wear and tear is inevitable – a matter of when and never if. And when it does occur, component put on inhibits pump efficiency. It is at that time where, timeously, mines could have to noticeably contemplate retrofitting as a possible choice.
A rational enterprise determination
In this setting, the place costs of capital equipment costs are rising, substitute could additionally be a wise enterprise determination. In an advisory focused at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business determination: “Retrofitting is an excellent alternative to purchasing a new product and could be performed on pumps regardless of their intended use. It is equally suitable for industrial, water supply and waste water disposal applications in addition to for the facility supply industry.”
It is only natural for mine operators to ponder acquiring new pumps. New pump models meet contemporary requirements like improved power efficiency, compliance with new authorized necessities (relating to emissions and safety), extended service life and technology which produces operating data. But this may not necessitate replacing an previous pump mannequin, KSB Pumps says, as retrofitting might give an previous pump a new lease of life, specifically within the following methods:
Save upkeep costs
Reduce power consumption
Achieve longer service life
Increase system availability
Comply with legal requirements (e.g: TA-Luft, ATEX)

Core areas in Retrofitting
The core focus areas in retrofitting are: hydraulic and mechanical modifications to the supplies, above and beyond changes to the supplies.
Hydraulic modifications
Some of the hydraulic modifications might involve:
Remachining of current impellers
Installation of latest impellers for off-design circumstances
Optimisation of volute casing for off-design situations
Adjustment of the number of levels (on multistage pumps)
Mechanical adjustments
The following are some of the mechanical modifications:
Closed bearing brackets improve the smoothness of operation and lengthen the bearing life
Installation of mechanical seal systems
Employment of mobile floor wear rings to improve efficiency, rotor dynamics and dry running properties
Use of optimised materials
The following are its a number of the supplies that a few of the optimised supplies that may be used:
Super duplex stainless-steel grades or nickel alloys
Ceramic mineral castings for impellers, put on plates, cover and casing – for use with finely dispersed, highly abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
