Pneumatic actuator manufacturers: What are the general types of actuators?


Release time:

2022-08-11

Pneumatic actuator manufacturer: Wuxi Xinming automatic control valve industry co., ltd. introduces you to several types of actuators? Actuators are generally divided into electric actuators and pneumatic actuators I. Electric Actuator Solenoid valve is a relatively simple electric actuator, it uses the electromagnet suction and release of small diameter valve for through, off two kinds of control, because the structure is simple, low price, often and two simple control device composed of simple active conditioning system. In addition to the solenoid valve, other successive actions of the electric actuator use the motor as a power element, the controller from the signal into the valve opening. The output mode of electric actuator has three types: straight stroke, angular stroke and multi-rotation, which can cooperate with linear moving conditioning valve, rotating butterfly valve, multi-rotation induction pressure regulator, etc. The signal from the controller drives the motor through the servo amplifier, drives the conditioning valve through the reducer, and feeds back the valve stem stroke to the servo amplifier through the position sensor to form a position follow-up system, relying on the negative feedback of the position to ensure that the input signal is accurately converted to the stroke of the valve stem. In the structure, the electric actuator can be integrated with the conditioning valve actuator, often separate sub-assembly to meet the needs of all aspects. In many process conditioning parameters, electric actuators can be used directly with a variety of electric conditioning appearances with different output signals. 2. pneumatic actuator Pneumatic actuator refers to the compressed air as the power of the actuator, it has a simple structure, large load capacity, fire and explosion-proof characteristics. Pneumatic actuators are mainly film type and piston type two categories, and the use of film actuators is relatively wide. The pneumatic piston actuator outputs thrust through the piston in the cylinder. Due to the large operating pressure of the cylinder, a relatively large thrust can be obtained, and a long-stroke actuator can be simply manufactured, so it is especially suitable for high static pressure, high pressure difference and demand Large thrust and displacement (corner or linear displacement) applications. Because pneumatic actuators require compressed air as power, they have a complete set of air source equipment more than electric actuators, and the use of installation and maintenance is more complicated, so they should not be used in buildings. The above is Wuxi Xinming automatic control valve industry Co., Ltd. introduced to you about the actuator generally has several types of all the contents, if you have any questions, please feel free to consult.
