A TACHOMETER to give continuous reading of exhauster-compressor speed is an option now offered by Whale Tankers of Solihull on its municipal and industrial vacuum tanker range.
The first tanker to be fitted with the tachometer, which, Whale claims, can contribute to long exhauster life as well as providing a check on performance, was built for the Department of the Environment Water Services, Belfast, on a 9080 litre (2000 gal) vacuum tanker.
Whale says high rates of blade wear which bring a marked reduction in efficiency are likely when a sliding-vane type exhauster is run either slower or faster than its recommended working speed range.
The 9080 litre (2000 gal) tanker is designed for cesspool emptying and is one of two for the DoE in Northern Ireland. It is also equipped for flushing out sewers with large quantities of clean water and is based on a 4013mm (158in) wheelbase Bedford TK 1630 chassis. The exhauster is a Hammond 340.
Four combination sewerjetter/gully and cesspool emptiers are to be supplied under the same order, placed by recently appointed Northern Ireland agents Roadside Motors Ltd of Lurgan.
