Pump retrofitting: New Lease of Life for Old Pumps

For เกจวัดแรงดันน้ำ of the commitment of a mine’s service staff to the beneficial best apply in pump administration, someday, encountering circumstances of pump component put on and tear is inevitable – a matter of when and not if. And when it does occur, component put on inhibits pump performance. It is at that point the place, timeously, mines might have to significantly consider retrofitting as a feasible option.
A rational business choice
In this setting, the place costs of capital gear costs are rising, replacement may be a wise business choice. In an advisory focused at mines and different industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business choice: “Retrofitting is a superb various to purchasing a brand new product and could be performed on pumps no matter their meant use. It is equally appropriate for industrial, water provide and waste water disposal purposes as well as for the facility provide industry.”
It is only natural for mine operators to ponder buying new pumps. New pump models meet contemporary necessities like improved vitality efficiency, compliance with new legal necessities (relating to emissions and safety), extended service life and know-how which produces working information. But this may not necessitate replacing an outdated pump mannequin, KSB Pumps says, as retrofitting might give an previous pump a brand new lease of life, particularly in the following ways:
Save maintenance costs
Reduce energy consumption
Achieve longer service life
Increase system availability
Comply with authorized requirements (e.g: TA-Luft, ATEX)
READ: Full-service capability very important for reliable pump provide
Core areas in Retrofitting
The core focus areas in retrofitting are: hydraulic and mechanical modifications to the materials, above and beyond adjustments to the supplies.
เกจวัดแรงดันเชื้อเพลิง of the hydraulic modifications could involve:
Remachining of current impellers
Installation of latest impellers for off-design situations
Optimisation of volute casing for off-design conditions
Adjustment of the number of stages (on multistage pumps)
Mechanical adjustments
The following are a few 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 surface wear rings to enhance effectivity, rotor dynamics and dry operating properties
Use of optimised materials
The following are its a variety of the materials that a variety of the optimised materials which 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, extremely abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
