week 20

Sketch of application available : NoYes, find enclosed ( upload ) Note – a brief sketch of the application really helps us provide a clear understanding of your application.
Confirm dimensions, please define the dimensions for your project using the sketch below and enter them in the following table.
sluice gate

*Required number of sluice gate drives:*

1.1 Sluice gate guide: Steel/WoodSteel/SteelSteel/PlasticSteel/Rubber sealRoller guide

1.2 Material for sluice gate: WoodSteel

Thickness: mm

1.3 Sluice gate width X = mm

1.4 Sluice gate height Y = mm

1.4.1 Water storage level Z = mm

* 1.5 Total weight of the sluice gate G = kg

* 1.6 Winch spacing for double sluice gate drive K = mm

1.7 Dimension A (sluice gate, top) A = mm

1.8 Required lift H = mm

1.9 Dimension C C = mm

1.10 Dimension D D = mm

1.11 Bore hole diameter U = mm

* Operating mode

2.1 Manual operation, lateral crank

2.2 Manual operation, by angular gear, crank centredFixed crank handleRemovable crank handleCrankshaft extension

Please specify dimension Q mm

2.3 Electric drive incl. stroke limit switches, load limiter and emergency hand wheel: 400 V three-phase current230 V AC24 V DCPosition of servo drive centrallateralhandwheel upstreamhandwheel downstream

2.4 Signal output 4-20 mA (2 x)other device

2.5 Control

3. Frequency of use

3.1 Actuation up to 10 x per annum

3.2 Actuation up to 100 x per annum

3.3 Actuation up to 500 x per annum

3.4 Continuous operation: On-Off mode > 10 x per day

3.5 Controlled operation

4. Installation situation

4.1 Application or use

4.2 Drives extended in their default position (closed)

4.3 Drives retracted in their default position (open)

4.2 Direction of bore hole “U” in the flow direction

4.3 Direction of bore hole “U” perpendicular to the flow direction

5. * Accessories

5.1 Rack covered with fixed protective tube

5.2 Rack with protective cap (rises with rack)

5.3 Surface protection: KTL coatingGalvanizedPowder coated RAL 9005other

6. Sluice gate ratio for sluice gate drive design
Sluice gate ratio = Y / X = / = from which we obtain: Y / X > 1.5 = Single sluice gate driveY / X < 1.5 = Double sluice gate drive

7. Required pulling force F F = [ µ × Y × ( Z − Y / 2 ) × X + G ] × S × 10 = (N)

Y = Height of sluice gate
Z = Total static height in dm. If the storage level is less than the sluice gate height put in this value
X = Width of sluice gate in dm
G = Total weight of sluice gate in kg
S = Safety factor (we recommend S = 2)
µ = Coefficient of friction (experience values) for: Wood/Steel = 0.45, Steel/Steel = 0.3, Steel/Plastic = 0.25, Steel/Rubber seal > 0,45 For rollers = 0.15
