What knowledge do you have to know when choosing an electric actuator?
An electric actuator is a drive device that can be linear or rotating. It is mainly used in valves. It is a device used to control the valve. Consumers need to pay attention to some things before choosing an electric actuator. What must be known when choosing an electric actuator Knowledge?
The torque of the valve needs to be determined, because the torque of the valve is related to the torque value of the electric actuator, and the torque value is generally provided by the consumer, and the valve manufacturer will choose and match the actuator according to this torque value. The actuator manufacturer is only responsible for the output torque, whether the valve can be opened and closed normally, this is completely determined by the valve diameter and pressure, but the valve manufacturer has certain differences in processing and production. Therefore, even valves of the same specification have a certain difference in torque. Even the torque of valves produced by the same manufacturer will be different. When consumers choose the torque of the valve, if the torque is too small, it will cause the valve to be too small. It cannot be opened normally, so before purchasing, be sure to provide the manufacturer with a range of torque.
The electrical parameters of the electric actuator. Electric actuator manufacturers will have a certain gap in electrical parameters, so you need to determine the value of electrical parameters before you choose an electric actuator, mainly including current, power, etc. If consumers ignore these factors, then it is very It is possible that the parameters of the electric actuator and the control system do not match each other. The final result is a trip, a blown fuse, or a tripping of the overload relay.
