The main advantages of electric actuators are high stability and constant thrust that can be applied by the user. The maximum actuator can generate thrust of up to 225000kgf. Only hydraulic actuators can achieve such a large thrust, but the cost of hydraulic actuators is higher than that of electric actuators. Much higher. The anti-deviation ability of the electric actuator is very good. The thrust or torque output is basically constant. It can overcome the unbalanced force of the medium and achieve accurate control of the process parameters. high. If equipped with a servo amplifier, it can easily realize the interchange of positive and negative effects, and it can also easily set the valve position of the break signal. When it fails, it must stay in place. The device must be protected by means of a combined protection system.
