前一场景
To address application problems of unplanned maintenance, failures and improve operational efficiency of the plant. Existing pumps operating receiving power by a diesel generator. Sites have been experiencing high failure rates with expensive repair costs; and proposed plans to increase flow rate and remain operational throughout the year. The size of the submersibles required a NPSH of 3-4 metres positive inlet pressure; which could only be achieved by lowering the pumps to a submerged position that was drawing rocks and heavy solids up from the bottom of the bed. By using the pumps above this level, cavitation was being experienced.
获得的优势
A solution was required to reduce downtime / maintenance costs and expensive failures. When a conventional submersible motor fails, it is not always economically to repair the motor, than buy a new pump.
Rather than replacing old for new, a thinking exercise was implemented to look at reducing overall LCC at the site, reducing obsolescence from scrap and improve efficiency and have more flexibility over the lagoon.
 
获得的优势
With Caprari’s linehsaft pump; the motor can be easily maintained above water level. The pump was able to absorb less power at higher heads, reducing overall running costs and routine maintenance costs.
Through collaboration with our customer: Hayley group, bespoke packages are readily available where a unitised floating pontoon system can be offered which also acts as a safe loading and storage frame, protecting  the equipment during installation and maintenance; so only planned maintenance is required. (designed for un-manned pontoon entry which can be easily lifted out of the lagoon)
