ニュージーランドの水処理プラントで、IQアクチュエータが防食フロー制御を提供
- 部門: 廃水
- カテゴリー: 電動アクチュエータ
- 製品: IQ - Standard, IQT - Part-Turn
概要
ニュージーランドにある数基の水処理プラントでは、既存の空気式アクチュエータにとって代わり、ロトルクの電動アクチュエータ(IQ及びIQT)が新設されました。
概要
Morrinsville、Matamata-Piako、Te Arohaにある3か所の大規模水処理施設とTe Poi、Hinuera、Te Hunaにある小規模施設から、Matamata-Piako及び周辺地域の全住民に飲料水が供給されています。
チャレンジ
The existing pneumatic actuators that provided several types of flow control had continual problems with sticking caused primarily because of the damp, chlorinated atmosphere in which they were operating. This caused degradation to the aluminium actuator body. A new reliable system was required and due to the sites being operated remotely, engineer safety when dealing with any breakdowns was a prime concern.
ソリューション
A solution was designed using Rotork IQT and IQS actuators. Rotork supplied these with stainless steel pedestals where required. The supplied IQ actuators provide control of filters, as well as the chemical dosing and storage of potable water.

Customer Benefits
The use of electric actuators will reduce the Matamata Piako District Council’s energy bill, as they will no longer have to power compressors to provide an air supply to pneumatic actuators.
The new actuators allowed for reduced operating noise and provide additional process and valve diagnostics via the HMI.
IQ actuators offer corrosion resistance, negating any degradation problems that the damp, chlorinated atmosphere caused the previous pneumatic actuators.
