This rating is based primarily on the location of the appropriate gate on the burden of water received, however not limited ESTRUAGUA, as it is in a position to consider, resolve and build any type of gate in accordance with customer needs ,

As drive systems of the gates, you can use the following procedures,

1 .- Manual.
2 .- electric gearmotor.
3 .- Power servo.
4 .- Water.

Manual operation .- Such action is conducted by means of a brass nut in conjunction with trapezoidal thread spindle, and a handwheel whose technical characteristics are described in the design of the gates also include bearings, ball bearings and bronze bushings or nylon. This drive on the gates of a single screw can be direct or via the reduction gear, thrust bearings or roller ball.

Drive by motor reducer .- The gearmotor to be introduced is applied depending on the size and hydraulic pressure in the gate. Optimal speed that will produce minimal wear of the screw in the rise of the gate (0.03 m / min.). The electric drive is accompanied by an electric torque limiter to avoid overexertion, and two limit switches in terms of bottoming.

In a screw locks the gear motor is directly coupled in gates of two screws were placed at the end or the center of the gate and always with two forwards. Take a manual emergency steering.

Driven by servomotor .- Be housed in the actuator stroke end, clutch, and regulatory mechanisms of the gate, which will regulate the levels. The wrath of the servomotor position depending on the number of spindles as the gearmotor.

Hydraulic .- Using hydraulic cylinders, only has application in a single screw gates. The stem is attached directly to the gate and the cylinder is anchored to the bridge of the gate. The system will be opening on-off.

Calculation of hydraulic pressure to channel gates:

L = Light free-span in meters. (W Channel)
H = Maximum water meters. (Lamina water channel)
Ph = hydraulic pressure on the board in kg

For gate channel with reinforced board and sheet rolls of displacement,

Ph = 500 x (L + 0.08) x H2

For all other choppers channel gates,

Ph = 500 x L x H2

Calculation of hydraulic pressure to channel gates:

L = Light free-span in meters. (W hole)
H = Maximum water meters. (Lamina water channel)
Ph = hydraulic pressure on the board in kg
H ‘= maximum load of water on the center of the gate. (Difference in gate sheet water)

H = Height in feet of the span.

To scroll roller gates,
Ph = 1000 H’x (L +0.1) x (h +0.05)

For small gates bottom outlets,
H’x Ph = 1000 (L 0025) x (h 0025)

For flat slide sliding
Ph = 1000 H’x (L +0.05) x (h +0.03)

Description gates:

Guide frame .- Built in stainless steel AISI 304 or 316, the board serves as a guide introducing concrete in civil works faster in the slots left for that purpose in the channel. The height of the frame is advisable to exceed 900mm in height from the floor of the maneuver.

Motherboard .- Built in stainless steel AISI 304 or 316, welded to the top of the frame. The brackets are placed drive. Shall consist of a rolled frame Upn where to attach cross-references where appropriate and necessary to drive the transmission from the side in the course of two spindles.

Gate board .- Made of sheet steel AISI 304 or 316 of thicknesses between 5.00 and 8.00 mm, with the necessary reinforcements to the soldiers rolled sheet and calculated to withstand the maximum hydraulic pressure. In the top center of the housing for carrying soldiers nut that gives movement to the board. In the center and take its entire length welded protection tube of the screw.

Travel Guides .- Low density polyethylene, a product with a very good self-lubricating sliding conditions. Are located at the ends of the board and supportive of this move through the frame that acts as a guide making transverse and longitudinal slip.

Seals .- The closure is made by stainless steel plates AISI 304 or 316 complementing the profile of neoprene Gr. 50-60 Shore A hole in the sides and bottom.

Clamping wedges .- Adjustable for a perfect fit, made of bronze, bolted to the board and the frame.

Drive Mechanism .- Comprising screw, steering wheel, column switching and forwarding. The spindle is made of trapezoidal screw DIN 109, stainless steel AISI 303, diameter depending on the length so as to limit the arrow to 1 / 1000 of the length.

Bring on the top for attaching a machined area of ​​the wheel support. The twin-screw assembly is made from gate width above 1200mm.

The nut is made of bronze material for driving the spindle. These will be housed in the top of the board or the bridge (column) depending on the procedure that is screw up or fixed.

The wheel is constructed of cast iron, will be housed in a bearing support with improving maneuverability.

Forwards .-They are airtight boxes which house a set of gears bevel pinion and crown, bearing trees, etc. Agree that vertical movement horizontally. Gates are mounted on twin-screw, depending on the effort needed to maneuver. The crown gear ratio will be 1:2 to reduce the torque required at the end of maneuver.
