Operating method for electric hydraulic water spraying unit of ship propulsion system

Abstract

The invention discloses an operating method for an electric hydraulic water spraying unit of a ship propulsion system. When an electric hydraulic water spraying propulsion device is started to advance, a storage battery pack supplies power to bidirectional oil hydraulic pump stations through circuits, and through a circuit control center, the two or more bidirectional oil hydraulic pump stations on the two sides are controlled simultaneously to control hydraulic cylinders on the two sides to simultaneously advance and retreat correspondingly; and a water pressure piston in a water pressure cabin on the other side retreats while a water pressure piston in a water pressure cabin on one side advances, and the water pressure pistons in the water pressure cabins on the two sides conduct propulsion alternately according to advancing and retreating to push a ship or an underwater vehicle to navigate. The hydraulic cylinders are driven through the storage battery pack and drive the water pressure pistons to travel to and from the interior of the water pressure cabins, water in the water pressure cabins is pressurized, and thrust of water spraying acts on a ship body to advance forwards; and the mute effect is good, energy conservation and emission reduction are achieved, and safety of the ship and the underwater vehicle navigating underwater can be guaranteed.

Description

technical field [0001] The invention relates to an operation method of a ship propulsion device for shipbuilding, in particular to an operation method of an electrohydraulic water jet unit of a ship propulsion system. Background technique [0002] At present, most ship propulsion devices in the traditional shipbuilding industry use engines to drive propellers. Since the engines used by ships occupy a large fixed space, they need to be matched with drive shafts and propellers, which affect the installation of other facilities on the hull. , Maintenance is a complex project, and replacement requires a large space; the parts wear out quickly during the use of the propeller propulsion, and the maintenance is frequent; when it is suitable for submersibles, the exhaust gas collection is large and the noise is large, causing manufacturers and users In view of the above-mentioned reasons, an operation method for the electro-hydraulic water jet unit of the ship propulsion system is n...
