For เกจวัดแรงดันถังออกซิเจน of the commitment of a mine’s service group to the beneficial greatest apply in pump administration, sometime, encountering circumstances of pump component wear and tear is inevitable – a matter of when and never if. And when it does occur, part wear inhibits pump performance. It is at that time where, timeously, mines might have to seriously contemplate retrofitting as a feasible option.
A rational enterprise choice
In this setting, where costs of capital gear costs are increasing, alternative could additionally be a smart enterprise determination. In an advisory focused at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business choice: “Retrofitting is a superb various to purchasing a brand new product and can be carried out on pumps no matter their supposed use. It is equally appropriate for industrial, water provide and waste water disposal applications in addition to for the power supply business.”
It is simply pure for mine operators to contemplate acquiring new pumps. New pump models meet modern necessities like improved vitality effectivity, compliance with new legal requirements (relating to emissions and safety), extended service life and expertise which produces operating information. But this will not necessitate replacing an previous pump mannequin, KSB Pumps says, as retrofitting might give an outdated pump a model new lease of life, particularly in the following methods: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)
READ: Full-service functionality very important for dependable pump supply
Core areas in Retrofitting
The core focus areas in retrofitting are: hydraulic and mechanical modifications to the supplies, above and beyond adjustments to the materials.
Hydraulic modifications
Some of the hydraulic modifications could contain:
Remachining of present impellers
Installation of new impellers for off-design situations
Optimisation of volute casing for off-design situations
Adjustment of the variety of stages (on multistage pumps)
Mechanical adjustments
The following are some of the mechanical modifications:
Closed bearing brackets enhance the smoothness of operation and lengthen the bearing life
Installation of mechanical seal systems
Employment of mobile surface put on rings to improve efficiency, rotor dynamics and dry operating properties
Use of optimised supplies
The following are its a few of the supplies that some of the optimised materials 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, extremely abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
