10 ton electrical actuators, 20 ton electric machine screw actuator for penstock gate valves at sewage treatment plant in pakistan
10 ton electrical actuators, 20 ton electric machine screw actuator for penstock gate valves at sewage treatment plant in pakistan. 8 ton loads input torque required T = [ (W x L1) / (2 x 3.14 x i x η) ] + T0 W: max. dynamic load / equivalent load per jack (n) L1: jack screw pitch (m), i: ratio, η: jack overall efficiency, T0: no-load torque (n) T = [(80000x0.01) / (6.28x40x0.13)] + 3.9 T = 28.4 nm 8 ton loads power required P1 = T x n1 / 9550 T: Input torque (nm), n1: input revolutions (rpm) P1 = 28.4 x 145 / 9550 P1 = 0.45 kw Supplying jt-20t jack & motor flange, without lifting screw, and low worm gear ratio 1/40, 0.25mm per turn of revolution, jt-20t jack max. dynamic load 8.4 ton, max. static load 20t. Model: JT-20T-L-M4. Matching 1/10 reduction ratio gear motor, output 145rpm. Gear motor power required must > 0.45 Kw, torque required > 28.4 nm, so selecting the closed gear motor power is 0.75kw. Special requirements: 400V AC, 50HZ, 3PHASE...
