HF 530 TILTING FLOW CHANNEL, 300 mm wide
The channel is designed for studying the hydraulic flow phenomena. It is a service unit to be used with optional accessories and models below. Instruction manual is also included.
Under Frame
The channel bed rests on twin beam under frame which ensures static loading deflections are kept to a minimum. Each section is shipped with glass side walls. This simplifies site installation as there is only one joint and is easier to ensure alignment of the channel. The beams are supported by a fulcrum at one end and an adjustable height support at the other end.
Slope Adjustment
The adjustable height support uses twin screws. Each screw is driven by a worm and wheel gear box with a common motor. A slope scale is provided at one end of the flume.
Channel Bed
The channel bed is made of stainless steel with screw holes of equal distance along the channel length to hold accessories or models to the channel bed. These holes can also be used for pressure tapping to measure pressure loss along the channel length.
Side Walls
For safety reasons, the side walls are made of tempered glass or clear acrylic. The walls are supported at interval by brackets with screw adjustment to ensure that the channel wall is straight and vertical.
Instrument Carriage
Top rails made of stainless steel tubes are attached to the top angle on each wall of the channel. Screws supporting the rails can be adjusted to ensure uniform height and in a straight line. A scale graduated in mm. is attached along the full length of one top angle of the walls. The instrument carriage is manually operated.
Head Tank
The head tank is made of stainless steel and bottom slope to ensure smooth flow into the channel. Perforated sheets are also provided in the head tank to further smoothen the flow.
Storage Tank
The storage tank has adequate water to fill the full channel. Fiber glass storage tank(s) is provided at downstream end of the channel. Capacity of tank varies according to channel length.
Model Installation
A mobile ladder is used. In the case of small fiber glass tanks (optional) are used, the top covers of the tanks (optional) are used as a walkway and model installation.
Circulating Pump
The pump seal is mechanical. A geared butterfly valves is provided for accurate flow control.
Flow measurement
A flow digital display is used for easy observation on flow adjustment. A water meter is available as an option and may be used as a reference for flow indicator setting later.
Model and Accessories
All accessories and models have side seals to ensure no water seepage or leakage through the sides of the models. A wide variety of models and accessories are available as an option.
