Neglecting bottom friction and atmos-pheric pressure decide the velocities 8 5 and 8 6 and the horizontal force re-quired to hold the gate if D 56 m D 61 m and L5 m. For doing so the sluice gate is made to move up and down with the help of rollers fixed to the vertical plates called skin plates which travel on vertical rails called guidesThese rails are fixed on piers or vertical walls as shown in Figure.

Slide 14 of 22. Kindly guide me about its flexiure and shear design. This factors assume a proper lubrication on stem threads if a poor maintenance is predicted multiply this factors by 115 to 13.
They have three main parts. Sluice Gate With Flow. Y X 15 Double sluice gate drive 7.
Sluice gate flow metering is often used to measure flow rate in open channels. Open the catalog to page 1. The moveable part.
Each application has a unique set of design variables which will impact the overall design of the gate. The control of each flow can only be achieved by the installation of sluice gates into channels and division boxes. Sluice gates are also often used to modulate flow.
Ideal Flow Theory No Energy Losses Q V 1 A 1 V 2 A 2. The incoming wastewater enters into inlet works which are divided into different channels by a division box. Weir gates mounted with unseating pressure particularly wide gates are subject to greater leakage because water pressure tends to deflect the slide away from the seals.
Slide 15 of 22. This drive shaft drives a worm gearlifting nut assembly. CALCULATE VELOCITY FLOW RATE FROM y1 y2.
Derivation of equation for unit-width discharge under a sluice gate. This means it takes 125 revolutions of the motor for one revolution of the worm gear assembly output. EXAMPLE Sluice gate A sluice gate controls flow in open channels.
The worm gear assembly has a 251 reduction. At sections 1 and 2 the flow is uniform and the pressure is hydrostatic. Slide 16 of 22.
In this paper a height automatic system is designed to set a certain height by using level sensor PLC and a three phase actuator with its transmission gear box.
