Amplifier electrohydraulic UEG. S-200

Electrohydraulic amplifiers (servovalves) like UEG.S, productions of PAO "NPP TEPLOAVTOMAT", represent devices which form a stream of working liquid to the executive mechanism with an expense proportional to an electric (current) signal of management. Electrohydraulic UEG.S amplifiers are widely used where exact regulation of force, acceleration, speed or situation is required.

Amplifiers are issued 8 standard sizes on a consumption of working liquid:

— UEG. S-10; — UEG. S-25; — UEG. S-63; — UEG. S-200;

— UEG. S-16; — UEG. S-40; — UEG. S-100; — UEG. WITH - 500.


Object of application of UEG.S are electrohydraulic control systems:
- equipment for vibration tests of materials, constructional knots and complete cars;
- stands modeling traffic conditions (flight, driving, swimming, etc.)
- industrial robots and manipulators;
- hydraulic and gas turbines;
- solution of rolls of rolling mills;
- press equipment;
- machine equipment;
- cars for alignment of railway tracks;
- arc melting furnaces;
- vibration devices for seismic exploration, etc.

Technical characteristics of UEG.S

Limits of change of an entrance electric continuous current signal of a direct current: minus 100 — 0 — plus 100 ma.
Resistance of an entrance chain: 60 ± 10 Ohms
Inductance of an entrance chain: no more 2gn
Effective value of current of an ostsillyation (the variable component with a frequency of 250+50 Hz imposed on an entrance signal): from 5 to 8ma.
Food pressure: 1,6-32 MPas.
Working environment: mineral oils.
Working range of temperatures of oil: from +20 to +70 °C

Oil consumption (at pressure difference on the amplifier of 10 MPas and the maximum entrance signal):
— UEG.S-10 — 10 ± 1 l/min;
— UEG.S-16 — 16 ±1,6 l/min;
— UEG.S-25 — 25 ± 2,5 l/min;
— UEG.S-40 — 40 ± 4 l/min;
— UEG.S-63 — 63 ± 6,3 l/min;
— UEG.S-100 — 100 ± 10 l/min;
— UEG.S-200 — 200 ± 20 l/min;
— UEG.S-500 — 500 ± 50 l/min.

Tolerance zone with a pressure of food of 32 MPas from the range of change of an entrance signal, no more: 0,4%.

Frequency corresponding to phase shift 90 ° (at an entrance signal of 20% of maximum), not less:
UEG.S-10; UEG.S-16; UEG.S-25 and UEG.S-40 220 Hz;
UEG.S-63. and UEG.S-100 120 Hz;
UEG.S-200 70 Of Hz;
UEG.S-500 27 Of Hz.

Average time between failures of T0 taking into account the maintenance regulated by the maintenance instruction: 66700 h.

Full average service life (at an average annual operating time of 2600 h and difference of pressure on the amplifier of 10 MPas): not less than 8 years.

Weight, no more:
— UEG.S-10; UEG.S-16; UEG.S-25 and UEG.S-40 2,1 kg;
— UEG.S-63 and UEG.S-100 2,7 kg;
— UEG.S-200 3,8 kg;
— UEG.S-500 7,8 kg.

Overall dimensions:
— UEG. S-10; UEG. S-16; UEG. S-25 and UEG. S-40 101 x 117 x 122 mm;
— UEG. S-63 and UEG. S-100 115 x 121 x 135 mm;
— UEG. S-200 138 x 125 x 142 mm;
— UEG. S-500 180 x 151 x 162 mm.
