For all the commitment of a mine’s service staff to the really helpful finest practice in pump management, someday, encountering circumstances of pump part wear and tear is inevitable – a matter of when and not if. And when it does occur, component wear inhibits pump efficiency. It is at that point where, timeously, mines could have to significantly contemplate retrofitting as a possible choice.
A rational business determination
In this setting, the place prices of capital gear prices are increasing, replacement could additionally be a smart enterprise decision. In an advisory focused at mines and different industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business decision: “Retrofitting is a superb different to buying a new product and could be performed on pumps regardless of their intended use. It is equally appropriate for industrial, water provide and waste water disposal functions in addition to for the ability supply business.”
เกจวัดแรงดัน is just natural for mine operators to contemplate acquiring new pumps. New pump models meet contemporary requirements like improved power efficiency, compliance with new legal necessities (relating to emissions and safety), extended service life and technology which produces operating information. But this may not necessitate replacing an previous pump model, KSB Pumps says, as retrofitting might give an outdated pump a brand new lease of life, particularly within the following ways:
Save maintenance prices
Reduce power consumption
Achieve longer service life
Increase system availability
Comply with authorized necessities (e.g: TA-Luft, ATEX)
READ: Full-service functionality very important for dependable pump provide
Core areas in Retrofitting
The core focus areas in retrofitting are: hydraulic and mechanical modifications to the supplies, above and beyond adjustments to the supplies.
Hydraulic modifications
Some of the hydraulic modifications may contain:
Remachining of existing impellers
Installation of recent impellers for off-design conditions
Optimisation of volute casing for off-design circumstances
Adjustment of the variety of phases (on multistage pumps)
Mechanical adjustments
The following are a few of the mechanical changes:
Closed bearing brackets improve the smoothness of operation and prolong the bearing life
Installation of mechanical seal methods
Employment of mobile floor put on rings to improve effectivity, rotor dynamics and dry working properties
Use of optimised supplies
The following are its some of the materials that some of the optimised materials that could 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, highly abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
