Kaplan Turbine Trainer Manufacturer,Supplier and Exporter in India

Product Code : SCL-CELE-14141

I. Overview and Principle

The Kaplan Turbine is an axial flow reaction turbine named in honor of Dr. B. Kaplan. This test rig is designed to demonstrate the operation and performance characteristics of the Kaplan Turbine, which is highly suitable for low head applications.

Principle: Turbine power is proportional to the product of discharge (Q) and head (H). To maintain power output when the head (H) is low, the Kaplan turbine is designed to handle a high discharge (Q).

II. Apparatus Description

The setup is a complete, self-contained unit used for conducting performance tests on the turbine.

• Main Components The unit includes a scroll casing housing the runner, a draft tube at the outlet, and a guide mechanism with stationary guide vanes.
• Flow Water is supplied to the turbine by a Centrifugal Pump. It enters through the guide vanes and passes axially through the runner.
• Runner The runner has a central hub and adjustable airfoil vanes mounted on it, a key feature of the Kaplan design.
• Shaft and Loading The runner is directly mounted on one end of a stainless steel shaft. The other end is connected to a rope brake arrangement for applying load, allowing calculation of the turbine’s efficiency.
• Observation A transparent hollow cylinder made of acrylic is fitted between the draft tube and the casing for visual observation of the water flow.
• Instrumentation Pressure and Vacuum gauges are fitted at the turbine inlet and outlet to measure the total supply head. The set-up is supplied with a control panel.

III. Technical Specifications

The specifications are provided for two versions: a Demonstration Test Rig and a higher-power 1 kW Test Rig.

A. Demonstration Test Rig Specifications

B. 1 kW Test Rig Specifications (Closed Circuit System)

IV. Structural Specifications (Common to both)

• Structure: Stainless steel frame.
• Fittings: All screws, nuts, plates, and metallic elements are stainless steel.
• Panel: Front panel features a schematic diagram matching the unit’s component distribution.
• Hydraulics: Quick connections for easy adaptation to hydraulic feed sources.

V. Experiments

The test rig enables students to determine the turbine’s performance characteristics:

1. Study of Kaplan turbine construction and components.
2. Determination of constant head characteristic curves.
3. Determination of constant speed characteristic curves.
4. Determination of constant efficiency curves.

VI. Computerization (Optional)

The unit offers optional computerization using Sci-cal Software and an Interface, often based on LabVIEW.

• Data Acquisition High-performance system for acquiring and processing various function parameters (Input and Output).
• Features Low cost, portable, compact, comprehensive, and sturdy design with full instrumentation.
• Measurement Direct reading and display of parameters like temperature, pressures, load, and power.
• Automation System has the unique feature of automatic calculation of all efficiencies and heat balance sheets.
• Software Capabilities Runs under Windows OS, featuring a diagrammatic representation with real-time sensor display, automatic data logging, sophisticated graph plotting (including comparisons), student questions, and detailed help screens. Data can be exported to Excel and read by other software like LabVIEW via a USB connection.
