Introduced pump pressure sensor to provide fault protection

Positive displacement pump specialist ROBBINS & MYERS has introduced a non-intrusive pressure sensor that protects the pump under dry operating conditions and under high pressure conditions.

The RM pressure sensor is designed to be mounted at the pump's outlet and is considered the most effective way to prevent pump dry operation, contrary to other conventional 'presence / disappearance' detectors, stator temperature probes and other interfering devices.

At the same time, positive displacement pumps are considered as one of the most versatile pump designs with the following advantages: They handle abrasive fluids with minimal wear; accurately measure viscous liquids; and deliver extremely sensitive products with major limitations (Just like most pump products) are run dry. However, using RM pressure sensors is one of the most effective ways for users to protect their positive displacement pumps or other processing equipment during dry operating conditions or high / low pressure conditions.

The device consists of sensors, pressure switches and control box composed of three basic components. The sensor is mounted between two standard ANSI flanges to allow fluid flow to be unobstructed. Pressure detection throughout the piping system ensures that the enclosure, fixture, or jumper does not affect the pressure reading. A further feature is the presence of a liquid-filled manometer that visualizes the pressure throughout the pump system.

Features

Application:The machine is used for series of chemical filament fiber twisting.

1. The machine is adopt servo motor and high strength belt, instead of mechanical cam, convenient maintenance, low power consumption and low noise. The guide rod is controlled by precise guide rail, it realized the precise electronic winding, stepless adjustable to ensure the good forming and unwinding of the bobbin.

2. The electronical system is adopt synchronous motor transducers technology, servo control system adopted to winding. The quality of yarn improved by real-time monitoring process speed.It can not only control the transmission precision,but also reduce the energy consumption, that caused unwinding easily.

3. It is more convenient operation by touch screen.

4. Using 320mm straight bobbin, maximum take-up capacity is 1.8kg.
