HYDRAULIC SYSTEM FOR DIVING BELL ROUND-TRIP DEVICE Russian patent published in 2010 - IPC B63C7/02 B63C11/44 F15B9/17 

FIELD: transport.

SUBSTANCE: invention refers to automatic regulation systems, namely to hydraulic systems intended for providing functioning round-trip equipment servicing deepwater operations, e.g. work of diving bell moved down from a ship. Hydraulic system for diving bell round-trip device contains at least two adjustable pumps, control system, the first hydromotor connected with weigh anchor hoist, the second hydromotor connected with diving bell hoist, hydraulic switching arrangement, pressure sensors, hydromotors speed sensors, as well as the first and the second aspect sensors of hoist revolving drums. The first aspect sensor is connected with weight anchor hoist, the second aspect sensor is connected with diving bell hoist, and their inputs are connected with control system inputs.

EFFECT: higher reliability and simpler design of the system.
