For all of the commitment of a mine’s service team to the beneficial greatest follow in pump administration, someday, encountering cases of pump component wear and tear is inevitable – a matter of when and never if. And when it does happen, element put on inhibits pump efficiency. It is at that time the place, timeously, mines might have to seriously contemplate retrofitting as a feasible choice.
A rational enterprise choice
In this surroundings, where prices of capital equipment costs are increasing, substitute may be a wise business determination. In เกจวัดแรงดูด focused at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational enterprise decision: “Retrofitting is a superb alternative to purchasing a brand new product and could be carried out on pumps no matter their intended use. It is equally suitable for industrial, water provide and waste water disposal purposes in addition to for the ability provide trade.”
It is only natural for mine operators to contemplate acquiring new pumps. New pump models meet modern requirements like improved vitality efficiency, compliance with new authorized necessities (relating to emissions and safety), prolonged service life and technology which produces operating information. But this will not necessitate replacing an old pump model, KSB Pumps says, as retrofitting could give an outdated pump a new lease of life, particularly within the following ways:
Save maintenance costs
Reduce power consumption
Achieve longer service life
Increase system availability
Comply with legal requirements (e.g: TA-Luft, ATEX)
READ: Full-service capability important for reliable pump supply
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 might involve:
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 phases (on multistage pumps)
Mechanical adjustments
The following are a few of the mechanical adjustments:
Closed bearing brackets enhance the smoothness of operation and prolong the bearing life
Installation of mechanical seal methods
Employment of cellular surface wear rings to improve efficiency, rotor dynamics and dry working properties
Use of optimised materials
The following are its some of the materials that a variety 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 – for use with finely dispersed, highly abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
