Abstract

The invention discloses a hydraulic control system for a water spraying propulsion device, and belongs to the technical field of water spraying propulsion. The hydraulic control system comprises a steering unit, an astern running unit and a load-sensitive pump. The steering unit comprises a first three-position four-way proportional reversing valve and a steering oil cylinder. The steering oil cylinder is a double-rod hydraulic cylinder. The astern running unit comprises a second three-position four-way proportional reversing valve and an astern running oil cylinder. The astern running oil cylinder is a double-rod hydraulic cylinder. Hydraulic oil is controlled through the first three-position four-way proportional reversing valve and the second three-position four-way proportional reversing valve, and forward and astern running and steering of a ship can be realized. Meanwhile, oil pressure and flow in the hydraulic control system can be automatically adjusted through a shuttle valveand the load-sensitive pump, and automatic overload protection and energy-saving control are realized.

Description

technical field [0001] The invention relates to the technical field of water jet propulsion, in particular to a hydraulic control system for a water jet propulsion device. Background technique [0002] The water jet propulsion device is a kind of ship propeller, which drives the ship to sail through the reaction force generated by the jet water. In order to realize the forward and backward of the ship, a reversing bucket is usually installed at the water nozzle of the water jet propulsion device. By controlling the reversing bucket to make an action, the water flow is sprayed forward or backward, thereby realizing the forward movement of the ship. and back. In order to realize the steering of the ship, a steering cover is usually installed at the water nozzle of the water jet propulsion device, and by controlling the steering cover to swing left and right, the water flow is sprayed to the left or to the right, thereby realizing the left and right turns of the ship. .
