Reaction Turbine (150W) Manufacturer,Supplier and Exporter in India

Product Code : SCL-CELE-14190

Overview

The Reaction Turbine Test Apparatus is a compact, compressed-air-operated trainer designed to study the characteristic behavior of a radial reaction turbine. The unit demonstrates the conversion of pressure energy into kinetic energy within the rotor — a principle fundamental to the operation of steam and hydraulic reaction turbines.

Air acts as the working medium and flows through four nozzle-shaped rotor exits, expanding and accelerating as it passes through. The resulting air jet imparts a reaction force on the turbine rotor, setting it into motion according to Newton’s third law of motion. The apparatus is housed within a transparent chamber, allowing clear observation of turbine operation.

The turbine load is applied using a band brake connected to a force sensor for torque measurement. Speed is measured via an optical speed sensor, while inlet and outlet pressures are displayed on precision manometers. The system includes a rotameter to measure volumetric airflow rate and an air preparation unit for pressure regulation.

The apparatus is also equipped with a quick-action stop valve for overspeed protection and a cooling system for the brake drum, ensuring safe and continuous operation. A digital display unit provides real-time readouts of torque, speed, and temperature.
