Pump retrofitting: New Lease of Life for Old Pumps

For เกจวัดแรงดัน300psi of a mine’s service staff to the really helpful best apply in pump administration, sometime, encountering instances of pump element put on and tear is inevitable – a matter of when and not if. And when it does happen, component put on inhibits pump efficiency. It is at that time the place, timeously, mines may have to noticeably contemplate retrofitting as a possible possibility.
A rational enterprise decision
In this surroundings, the place prices of capital tools costs are increasing, substitute could also be a sensible enterprise decision. In an advisory targeted at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational enterprise determination: “Retrofitting is a superb alternative to purchasing a model new product and may be carried out on pumps regardless of their supposed use. It is equally suitable for industrial, water provide and waste water disposal applications in addition to for the ability provide business.”
It is just pure for mine operators to ponder acquiring new pumps. New pump models meet up to date necessities like improved energy efficiency, compliance with new authorized requirements (relating to emissions and safety), extended service life and know-how which produces working knowledge. But this may not necessitate replacing an previous pump model, KSB Pumps says, as retrofitting could give an previous pump a new lease of life, specifically within the following methods:
Save upkeep prices
Reduce energy consumption
Achieve longer service life
Increase system availability
Comply with legal requirements (e.g: TA-Luft, ATEX)
READ: Full-service capability 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 past modifications to the materials.
Hydraulic modifications
Some of the hydraulic modifications could contain:
Remachining of present impellers
Installation of latest impellers for off-design conditions
Optimisation of volute casing for off-design situations
Adjustment of the number of phases (on multistage pumps)
Mechanical adjustments
The following are a number of the mechanical changes:
Closed bearing brackets enhance the smoothness of operation and extend the bearing life
Installation of mechanical seal systems
Employment of mobile surface wear rings to improve efficiency, rotor dynamics and dry operating properties
Use of optimised materials
The following are its some of the materials that a variety of the optimised materials which might be used:
Super duplex stainless-steel grades or nickel alloys
Ceramic mineral castings for impellers, put on plates, cover and casing – to be used with finely dispersed, extremely abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
