YT1-25 Electro-hydraulic Thruster

Electro-hydraulic propeller is a kind of propulsion equipment which uses electric control and hydraulic transmission. Its main advantages include:

1. High thrust. Electro-hydraulic thrusters can provide large thrust and meet the needs of many high-load and high-speed scenes.

2. Provide high acceleration in a short time. Due to the characteristics of hydraulic transmission, the electro-hydraulic propeller can provide high acceleration in a short time, thus meeting the application scenarios such as instant start and emergency stop.

3. High precision. Due to the incompressibility of hydraulic oil and the accuracy of electrical control, electro-hydraulic thruster can provide high control accuracy.

4. Low energy consumption. Compared with other transmission modes, the electro-hydraulic propeller has lower energy consumption.

However, the shortcomings of the electro-hydraulic propeller can not be ignored:

1. The system is complex. Electro-hydraulic propeller needs technical support from hydraulic transmission, electrical control and mechanical structure, and the system complexity is high.

2. It's noisy. Due to the mechanism of hydraulic transmission, the electro-hydraulic propeller will produce great noise when working, so it is necessary to take noise control measures.

3. High maintenance cost. Electro-hydraulic thrusters need regular replacement of hydraulic oil, inspection of valves, inspection of pipelines and other maintenance tasks, and the cost is high.

The working principle of the electro-hydraulic pusher is that the motor drives the oil pump to work, so that the hydraulic oil enters the oil cylinder, so that the oil cylinder has a certain thrust, thereby driving the required mechanism to move. At the same time, the inlet and outlet of hydraulic oil are controlled by electrical control system to realize accurate control of thrust.
