For all the dedication of a mine’s service staff to the really helpful best follow in pump administration, someday, encountering circumstances of pump element put on and tear is inevitable – a matter of when and never if. And when it does happen, part wear inhibits pump efficiency. It is at that time where, timeously, mines might have to seriously consider retrofitting as a possible choice.
A rational enterprise decision
In this environment, the place costs of capital tools costs are growing, replacement could also be a sensible enterprise choice. 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 could be carried out on pumps regardless of their intended use. It is equally suitable for industrial, water supply and waste water disposal purposes in addition to for the facility supply industry.”
ความหมายของเครื่องวัดความดัน is simply pure for mine operators to contemplate acquiring new pumps. New pump fashions meet modern necessities like improved vitality efficiency, compliance with new legal requirements (relating to emissions and safety), prolonged service life and technology which produces working information. But this may not necessitate changing an previous pump mannequin, KSB Pumps says, as retrofitting may give an previous pump a new lease of life, specifically within the following methods:
Save maintenance costs
Reduce energy consumption
Achieve longer service life
Increase system availability
Comply with legal requirements (e.g: TA-Luft, ATEX)
READ: Full-service functionality very 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 beyond modifications to the materials.
Hydraulic modifications
Some of the hydraulic modifications might contain:
Remachining of current impellers
Installation of recent impellers for off-design situations
Optimisation of volute casing for off-design conditions
Adjustment of the variety of stages (on multistage pumps)
Mechanical changes
The following are a few of the mechanical modifications:
Closed bearing brackets enhance the smoothness of operation and prolong the bearing life
Installation of mechanical seal systems
Employment of mobile surface wear rings to improve efficiency, rotor dynamics and dry working properties
Use of optimised materials
The following are its a few of the materials that a few of the optimised supplies which may be used:
Super duplex chrome steel grades or nickel alloys
Ceramic mineral castings for impellers, wear plates, cowl and casing – for use with finely dispersed, highly abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
