Novel ship hydraulic steering engine

Abstract

The invention discloses a novel ship hydraulic steering engine, and relates hydraulic steering engines. The technical problem that an existing hydraulic steering engine is poor in safety is mainly solved. The novel ship hydraulic steering engine comprises a steering mechanism. The novel ship hydraulic steering engine comprises a steering mechanism and further comprises an electromagnetic reversingsteering oil way and a manual steering oil way which supply oil independently, the input end of the electromagnetic reversing steering oil way is connected with a first oil tank, and the output end of the electromagnetic reversing steering oil way is connected with the steering mechanism through an automatic isolation valve. The input end of the manual steering oil way is connected with a secondoil tank, the output end of the manual steering oil way is connected with the steering mechanism through the automatic isolation valve, the electromagnetic reversing steering oil way is provided witha first isolation oil way connected with the first control end of the automatic isolation valve, and correspondingly, the electromagnetic reversing steering oil way is provided with a second isolationoil way connected with the second control end of the automatic isolation valve. The manual steering oil way is provided with a second isolation oil way connected with the second control end of the automatic isolation valve. The novel ship hydraulic steering engine is high in safety and high in working stability.

Description

technical field [0001] The present invention relates to a hydraulic steering gear, more specifically, it relates to a novel marine hydraulic steering gear. Background technique [0002] As a component of the ship's steering system, the marine hydraulic steering gear is the most important component of the ship except the main engine. How to ensure the safe navigation of the ship is the top priority. In recent years, with the Pearl River Golden Waterway in our region, the construction of the Greater Bay Area, the Beibu Gulf Economic Zone, etc., the tonnage of ships has increased, and the number of ships has increased day by day. The safety of hydraulic steering gear bears the weight of the safety of ships in the entire Pearl River navigation area. . [0003] The hydraulic steering gear is one of the important deck machinery of the ship, and its function is to change and maintain the ship's course. The steering gear work is directly related to the navigation safety of the shi...

AI Technical Summary

Problems solved by technology

The existing hydraulic steering gear has the following disadvantages: the electromagnetic reversing steering oil circuit A and the manual steering steering oil circuit B share a two-position three-way solenoid valve E. Once the two-position three-way solenoid valve E is stuck or leaks, the It cannot be isolated, which is prone to accidents; the electromagnetic reversing steering oil circuit A and the manual steering steering oil circuit B share a fuel tank C. When the oil tank or pipeline or accessories leak oil, the hydraulic oil capacity in the fuel tank cannot meet the needs of the system , unable to steer; manual isolation valve H is used, which is a three-way connection in normal use. When one of the power equipment or pipelines fails, personnel run from the pilothouse to the steering gear cabin at the stern, open the left and right steering gear cabin covers respectively, and then close The manual isolation valve of the faulty pipeline or equipment takes about 5 minutes. During this time, the direction of the ship is out of control, and the probability of accidents such as collision with the ship or bridge pier is very high. This process takes a long time and cannot guarantee 10-second isolation failure and switching to another power unit steering

Therefore, the existing hydraulic steering gear has the problem of low safety
