    • A control device for operation of an autoclave pump of a water distribution network, of the type comprising a mechanical part, with the task of detecting pressures and flows by means of moving parts, and an electronic part, with the task of managing pump supply in relation to the parameters detected; all signals are sent to a microprocessor electronic control system which, thanks to simultaneous detection and measurement of flow and pressure, makes it possible to avoid the pressure oscillation typical of control devices of the traditional type and prevent the pump from starting up and shutting down continually. The device is also capable of detecting any abnormal conditions that take place, such as excessive flow, no water at the pump inlet side or a leak in the user circuit, taking steps to shut down operation of the entire system to prevent damage to the pump and the internal circuits.
    • 一种控制装置,用于配水网络的高压灭菌器泵的操作,该控制装置包括机械部件,其具有通过移动部件检测压力和流量的任务,以及电子部件,其任务是管理泵供应 与检测到的参数的关系; 所有信号都被发送到微处理器电子控制系统,由于同时检测和测量流量和压力,可以避免传统类型的控制设备典型的压力振荡,并防止泵持续启动和关闭 。 该装置还能够检测发生的任何异常情况,例如流量过大,泵入口侧没有水或用户回路泄漏,采取措施关闭整个系统的运行以防止损坏泵 和内部电路。
