PURPOSE

The Avitech AV843 Hydraulic Pump and Accessories Test Stand is designed to accurately perform overhaul and post overhaul acceptance tests on

actuating cylinders, solenoid valves, reservoirs, accumulators, pumps, and other components .

Capabilities of the AV843 Test Stand include producing and maintaining drive speeds, flow rates, temperatures, and pressures, as required when testing components.

and faci lities for mounting and driving hydraulic pumps The )The Test Stand consists of a drive console and a control console. The drive console encloses a reversible, variable speed drive, an electric motor, control console contains the instrumentation, electrical control circuits, storage compartment and writing surface.

The Test Stand utilizes a low pressure boost pump, high pressure hydraulic pump and an air-operated hydraulic booster.

All required instrumentation to perform tests on the necessary components has been provided with accuracies meeting or exceeding specifications in the applicable Technical Orders.
