main features 

1. The shell is made of cast aluminum alloy, with light weight and beautiful appearance;

2. The motor is a non oil immersed structure, with Class B or F insulation (according to user requirements), good heat resistance, and long service life;

3. The motor junction box is equipped with a seal and uses a cable stuffing box for incoming lines, which is firm and reliable. The electrical casing protection level reaches IP55;

4. The surface of the motor shaft and push rod are specially treated, greatly extending the service life of the sealing element;

5. The oil cylinder shell is equipped with a balance chamber on one side, allowing the thruster to be installed in any direction from 0 to 180 °, thereby expanding its range of use;

6. All seals and bearings are made of world-renowned products, with reliable sealing and long service life;

7. The fasteners are made of stainless steel material, which is beautiful and durable.

Additional devices

1. Upper limit switch: can indicate whether the brake is on, whether the push rod is pushed to the specified position, and other information;

2. Lower limit switch: can indicate whether the brake is correctly closed, whether the push rod returns to the specified position, and can also set the upper and lower limit switches;

3. Add a built-in spring (only available for short stroke thrusters), with the spring force determined by the user but not exceeding the built-in spring force (see parameter table);

4. Adding a heater: When the ambient temperature at the place of use is below -25 ℃, users can add a heater as needed. The heater parameter table is shown in Appendix 1;

5. The rising time delay valve and the falling time delay valve can extend the rising or Fall time steplessly. The delay range is from the rated action time to 30 seconds. The specific delay value can be adjusted according to the user's requirements. All push rod connection blocks of thrusters can rotate. The Ed50-Ed301 fixed seat can rotate 90 °, while the Ed23-Ed30 fixed seat can also provide 90 ° rotation, but the installation height dimension A is increased by 8mm;

Regardless of the installation position, the piston rod cannot withstand any force to avoid affecting its effectiveness and lifespan.

Question:

[Single choice] The slow rise of the push rod of the electric hydraulic thruster is not the reason.

A Insufficient oil quantity

B The main spring is too tight

C Improper use of low temperature oil

D Voltage too low
