We aim to provide mine operators with a rapid method of detecting and removing calcium and similar deposits from in service check valves without stopping production, thus extending the life of expensive components, reducing the cost of maintenance by 50%pa and downtime by 5%pa. In the case of cyanidation, exposure of maintenance operatives to cyanide will be reduced to zero for certain tasks, presenting obvious health benefits. The system will reduce the risk of contamination from back-flow, and could be applied to other industries where check valves (or similar) are used, eg petrochem, nuclear or hydropower generation. A novel ultrasonic cleaning method will be developed: the components themselves act as a cleaning bath so are not removed from service. A device consisting of a wave generator, amplifiers and high power ultrasonic transducers will be clamped to accessible surfaces of the valve to remove well adhered debris effectively without chemicals.

我们的目标是为矿山经营者提供一种快速检测和去除在用止回阀中钙和类似沉积物的方法，而无需停止生产，从而延长昂贵部件的使用寿命，减少50%的维护成本和5%的停机时间。在氰化的情况下，维护人员暴露于氰化物的某些任务将减少到零，呈现出明显的健康效益。该系统将降低回流污染的风险，并可应用于其他使用止回阀（或类似）的行业，例如石油化工、核能或水力发电。一种新的超声波清洗方法将被开发：组件本身作为一个清洗槽，因此不需要从使用中移除。一个由波发生器、放大器和高功率超声波换能器组成的装置将被夹在阀门可触及的表面上，以有效地去除粘附良好的碎屑，而不需要化学物质。
