For all the dedication of a mine’s service staff to the recommended finest practice in pump administration, someday, encountering circumstances of pump part put on and tear is inevitable – a matter of when and not if. And when it does happen, component put on inhibits pump performance. It is at that time the place, timeously, mines could have to seriously think about retrofitting as a possible choice.
A rational business choice
In this environment, the place costs of capital tools costs are growing, alternative may be a smart enterprise determination. In เพรสเชอร์เกจคือ at mines and different industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business decision: “Retrofitting is a wonderful alternative to purchasing a brand new product and may be carried out on pumps regardless of their intended use. It is equally suitable for industrial, water supply and waste water disposal applications as properly as for the facility provide business.”
It is only pure for mine operators to ponder buying new pumps. New pump models meet modern requirements like improved vitality effectivity, compliance with new legal necessities (relating to emissions and safety), extended service life and expertise which produces working information. But เกจวัดแรงดันแก๊สco2 may not necessitate changing an previous pump model, KSB Pumps says, as retrofitting may give an old pump a new lease of life, particularly in the following ways:
Save maintenance costs
Reduce power consumption
Achieve longer service life
Increase system availability
Comply with authorized 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 materials, above and past changes to the supplies.
Hydraulic modifications
Some of the hydraulic modifications could contain:
Remachining of existing impellers
Installation of recent impellers for off-design circumstances
Optimisation of volute casing for off-design situations
Adjustment of the number of levels (on multistage pumps)
Mechanical changes
The following are a number of the mechanical changes:
Closed bearing brackets enhance the smoothness of operation and prolong the bearing life
Installation of mechanical seal techniques
Employment of cellular surface put on rings to enhance efficiency, rotor dynamics and dry working properties
Use of optimised supplies
The following are its a number of the supplies that some of the optimised materials which could be used:
Super duplex stainless-steel grades or nickel alloys
Ceramic mineral castings for impellers, wear plates, cowl and casing – for use with finely dispersed, highly abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
