HYDRAULIC TEST STAND DIESEL ENGINE DRIVEN 16 GPM AT 3000 PSI, MAX OPERATING PRESSURE 4500 PSI

MAIN FEATURES:

Hydraulic Test Stand mounted on a steerable trailer (steel structure) equipped with four pneumatic wheels, towing through a tow-bar at the maximum speed of 30 Km/h.

Rear wheels are equipped with hand operated drum brake.

Axial piston type, high pressure, diesel engine driven pump with variable displacement and adjustable working pressure up to 16 GPM at 3000 psi or 10 GPM at 4500 psi.

High Pressure 2 m filter on delivery line equipped with differential pressure switch for filter clogged indication

Low pressure 25 m filter.

Stainless steel reservoir, volume 120 litres, operative capacity 90 litres, equipped with:

• inspection hole

• fluid level sight indicator

• drain valve

• filling and drain port

• suction and return port

The HTS may be used with aircraft reservoir or test stand reservoir.

Sampling port to check the fluid class (according to NAS 1638).

Ambient working temperature: from -20 °C to +50 °C.

Working fluid: MIL-PRF-5606, MIL-PRF-83282 and MIL-PRF-87257. On request Skydrol fluid.

Proportional electric valve, with by-pass function, to set and control the max working pressure.

Mechanical relief valve, to pilot the pump compensator, for the adjusting of the actual working pressure.

The HTS is Dual System (2 completely independent branches, each branch composed by one delivery line and one return line), it is possible to operate with different pressures (with the aid of two pressure reducing valves) on both circuits simultaneously. On return line the back pressure can be adjusted.

INSTRUMENTATION:

H.P. gauge, branch “A”, F.S. 6000 PSI, accuracy 0,6% f.s., case filled with silicon oil for low temp.

H.P. gauge, branch “B”, F.S. 6000 PSI, accuracy 0,6% f.s., case filled with silicon oil for low temp.

L.P. gauge, return / booster pressure, F.S. 160 PSI, accuracy 0,6% f.s., case filled with silicon oil for low temp.

Flowmeter, LPM or GPM and Thermometer, °C digital indicatio.

Fluid level sight indicator. Diesel fuel level. Engine RPM indicator with hour counter integrated.

DIESEL ENGINE:

Deutz type F4L1011, 4cylinders, air cooled.

Power rating: continuous 31 KW @ 2000 RPM.

Starting motor: 24 v, 4KW. Ancillary alternator: 40 A at 28 V. N° 2 battery of 70 Ah.

OPTION:

The test stand can be equipped with a Laser Particle Counter (P/N KLP-120), for continuous monitoring the hydraulic fluid, without sampling it, for presence of particles and/or water presence inside the fluid.
