For all the dedication of a mine’s service staff to the beneficial greatest practice in pump administration, sometime, encountering circumstances of pump component put on and tear is inevitable – a matter of when and never if. And when it does happen, component wear inhibits pump efficiency. It is at that time the place, timeously, mines may have to noticeably contemplate retrofitting as a feasible choice.
A rational business decision
In this setting, the place costs of capital tools prices are increasing, replacement may be a sensible business decision. In an advisory targeted at mines and different industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business choice: “Retrofitting is an excellent various to purchasing a new product and can be carried out on pumps regardless of their supposed use. It is equally suitable for industrial, water supply and waste water disposal purposes as well as for the facility supply trade.”
เกจวัดแรงดันเบนซิน is simply natural for mine operators to contemplate acquiring new pumps. New pump models meet contemporary necessities like improved energy efficiency, compliance with new authorized requirements (relating to emissions and safety), extended service life and know-how which produces operating data. But this may not necessitate replacing an previous pump mannequin, KSB Pumps says, as retrofitting may give an old pump a model new lease of life, particularly in the following methods:
Save maintenance 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 supplies, above and beyond changes to the materials.
Hydraulic modifications
Some of the hydraulic modifications could contain:
Remachining of present impellers
Installation of latest impellers for off-design circumstances
Optimisation of volute casing for off-design circumstances
Adjustment of the number of stages (on multistage pumps)
Mechanical adjustments
The following are a number of the mechanical adjustments:
Closed bearing brackets improve the smoothness of operation and lengthen the bearing life
Installation of mechanical seal techniques
Employment of cellular floor wear rings to enhance efficiency, rotor dynamics and dry working properties
Use of optimised materials
The following are its some of the supplies that some of the optimised materials that might be used:
Super duplex stainless steel grades or nickel alloys
Ceramic mineral castings for impellers, put on plates, cowl and casing – for use with finely dispersed, extremely abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
