The thruster mainly consists of three parts: electric motor, centrifugal pump, and hydraulic cylinder. The motor shaft is hollow and connected to the square shaft through a coupling. The end of the square shaft is equipped with a centrifugal impeller. When the push rod acts, the square shaft slides up and down in the hollow motor shaft and transmits torque.

When energized, the electric motor drives the impeller to rotate, generating oil pressure to push the piston push rod up rapidly. When the rated stroke is completed and the specified oil pressure is reached, the piston rapidly drops under the action of external load and returns to its starting position.

5 Technical parameters and external installation dimensions

6. Installation adjustment and usage requirements

6.1 Installation of thrusters

6.1.1 Firstly, check if the model on the nameplate of the thruster matches the requirements.

6.1.2 When the thruster leaves the factory, there is no working oil and it cannot be used directly. When using it, first add pure hydraulic oil from the oil filling hole (5) to the oil level hole (3). Pay attention to pulling the push rod up and down several times during the oil filling process to eliminate air and fill the oil cylinder with oil, and then tighten the plug.

6.1.3 The thruster is used for vertical or inclined installation not exceeding ± 15 °, with the connecting rod (7) facing upwards.

6.1.4 After installation, the thruster should be able to swing as a whole during operation, and the push rod is not allowed to bear radial force.

6.1.5 The thruster is equipped with qualified motors that have obtained explosion-proof certificates.

When wiring the thruster motor, it is necessary to carefully compare the wiring with the motor nameplate.

6.1.7 The diameter of the motor inlet cable should match the hole of the rubber pad, ensuring that there is no gap between the silicone rubber pad and the cable and outlet, otherwise the explosion-proof performance will be lost.

6.1.8 The thruster is equipped with grounding screws, and users should ground it according to relevant regulations when using it. Do not open the cover with electricity!!!

6.2 Use of thrusters

6.2.1 Before use, it should be checked according to Article 5.1, and once it is correct, it can be put into use.

6.2.2 Regularly check whether the thruster works normally, whether there is oil leakage, and maintain a certain amount of oil.

6.2.3 Check the oil every six months, and change the oil when it deteriorates or gets mixed with debris (see 5.1.2).

6.2.4 Based on the temperature of the surrounding medium, it is recommended to select hydraulic oil according to the following table:

When the thruster is in operation, the lower end of the piston should be kept at a certain distance (generally not less than 5mm) from the cylinder bottom, otherwise it will affect normal operation.

7. Usage and Maintenance

7.1 Before use, it should be checked according to Article 6.1, and once it is correct, it can be put into use.

7.2 Regularly check the operation of the thruster, whether there is any oil leakage, and maintain a fixed amount of oil.

Warning: It is strictly prohibited to set up oil collection pits. Strengthen inspections and promptly handle any oil spills or leaks that are discovered.

7.3 Check the oil every six months, and when the oil deteriorates or gets mixed with debris, the oil should be changed (see Article 6.1.2).

8. Storage and transportation

8.1 When storing thrusters, they should be kept dry to prevent moisture and sharp changes in ambient temperature.

8.2 During transportation, it is necessary to prevent rain and not use a rope to cover the push rod for transportation.
