Embodiment Construction

[0022] In Fig. 1, when the system works normally, the first two-way quantitative pump-motor 19 is working under the motor condition, and the first ship main engine 1 drives the first two-way variable variable pump 2 to supply oil to the first two-way quantitative pump-motor 19 to drive The first propeller 20 rotates to provide driving force for the ship. Driven by the first ship main engine 1, the first fuel pump 5 sucks oil from the oil tank 6, supplies oil to the low-pressure side of the system through the first check valve 3 or the second check valve 4, and stabilizes the pressure through the first accumulator 17 Afterwards, the first supplementary oil pump 5 provides control oil for the first servo cylinder 9 and the first servo valve 10 while supplying oil to the low pressure side of the system. The variable mechanism of the first two-way variable pump 2 is composed of the first servo cylinder 9 and the first The servo valve 10 is controlled, and the first overflow valve ...

Abstract

The present invention provides a pushing method and device which is used in shipping and other vehicle in water. The method is based on hydraulic transmission principle. Mechanical energy exported by a shipping mainframe is transformed to pressure energy of hydraulic oil by a two-way variable displacement pump. An airscrew and other assist device are respectively driven. The pressure energy of the hydraulic oil is transformed to mechanical energy of the airscrew by a hydraulic motor. The two-way variable displacement pump and the shipping mainframe are controlled to adjust rotate speed and veer of the airscrew in order to adjust diversified motion conditions of the shipping. The energy exported by the hydraulic motor in dumping condition is withdrawn by using a hydraulic accumulator, and the energy is released in a process of reversing and accelerating. Two shipping mainframes work in multi method, which is realized through switching of pipeline. The pushing method has the advantages of flexible cabin disposal, high power weight ratio of device, good safety and reliability, high maneuverability and good condition combining characteristics.

Description

technical field [0001] The invention relates to a ship propulsion method and device, that is, based on the principle of hydraulic transmission, the mechanical energy output by the main engine of the ship is converted into the pressure energy of hydraulic oil through a two-way variable pump to drive propellers and other auxiliary devices respectively. The pressure energy of the hydraulic oil is converted into the mechanical energy of the propeller by the hydraulic motor, and the speed and steering of the propeller are adjusted through the control of the two-way variable pump and the main engine of the ship to adapt to various motion conditions of the ship. The hydraulic accumulator is used to recover the energy output by the hydraulic motor under the pump condition, and release the energy during the commutation acceleration process. Through pipeline switching, the two main engines of the ship can work in various ways. It is mainly used on all kinds of ships, warships, submarin...
