Hydraulic system for steering engine of glass fiber reinforced plastic ship

Abstract

The invention relates to the technical field of ship manufacturing, in particular to a hydraulic system for a steering engine of a glass fiber reinforced plastic ship. The hydraulic system comprises a hydraulic oil pump, a motor, an oil tank, a hydraulic reversing valve and a bidirectional hydraulic oil cylinder. The hydraulic system is characterized in that the hydraulic oil pump is driven by the motor; a liquid outlet of the hydraulic oil pump and a liquid inlet of the hydraulic oil pump are respectively connected with a liquid inlet of the bidirectional hydraulic oil cylinder and a liquid outlet of the bidirectional hydraulic oil cylinder through a guide pipe; the hydraulic reversing valve is arranged on the guide pipe; a liquid inlet of the oil tank and a liquid outlet of the oil tank are connected to the guide pipe in series through a liquid guide pipe so as to form a hydraulic loop; telescopic rods of the bidirectional hydraulic oil cylinder are connected with a left transmission handle and a right transmission handle. Through the use of the hydraulic system disclosed by the invention, a limited space in the ship is greatly saved; the hydraulic system has the advantages of compact structure, space conservation, low noise, flexible movement and the like, is convenient to mount and maintain, and is particularly suitable for a glass fiber reinforced plastic yacht and a glass fiber reinforced plastic mosquito boat.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a hydraulic system for a FRP ship steering gear with simple structure, low noise and flexible operation. Background technique [0002] As we all know, hydraulic transmission technology is widely used in industrial and civil industries due to its large transmission force, flexible control, easy transmission and configuration. With the continuous development of hydraulic technology and the development trend of ships, hydraulic technology is more widely used in the field of ships. Now The steering gear system of some ships is uniformly mechanical. It is mainly composed of rudder stock, upper bearing, lower bearing, rudder pin bearing, rudder shaft, rudder blade and rudder pin. The disadvantages are high processing accuracy and installation requirements, and high production cost. High, noisy, inflexible operation, large space occupation, etc. Contents of the invention [0003...
