How to make scientifically correct choices and understand in the constantly evolving society of todaypneumatic actuatorWhat about it? I don't think it's a concern for friends who need pneumatic actuators, so let's explain the relevant knowledge and correct selection of pneumatic actuators below.
First, let's proceedactuatorThe types of actuators are divided into electric and pneumatic. That is to say, the power sources used are different. However, different power sources result in varying parameters of pneumatic actuators. By adding the differences in usage and usage of pneumatic actuators produced by various manufacturers, it is easy to form diverse pneumatic actuators. So it is necessary to choose what kind of pneumatic actuator to use based on scientific knowledge.
Next, we will focus on introducing commonly used onespneumatic actuatorHis working principle and some other related knowledge. Pneumatic actuators are divided into single acting (spring reset) and double acting. Drive the screw rod to rotate the valve stem through compressed air. Select the actuator based on the size of the gas source (instrument gas). The torque required to rotate the valve is too small to move, and too large will shorten the lifespan of the valve. Generally, leaving a 30% margin for torque is sufficient. There are standards for installing platforms, as long as you find the right standard based on the valve, there will be no mistakes.
pneumatic actuatorThe executing mechanism and regulating mechanism are a unified whole, and their executing mechanisms include membrane type, piston type, and gear rack type. Piston type with long stroke, suitable for situations requiring high thrust; The thin film type has a smaller stroke and can only directly drive the valve stem. Due to its simple structure, high output thrust, stable and reliable operation, as well as safety and explosion-proof advantages, gear rack pneumatic actuators are widely used in production processes with high safety requirements such as power plants, chemicals, and refineries.
Based on the above, let's summarize how to scientifically choose the pneumatic actuator that suits your needs. Firstly, it is necessary to have a clear understanding ofpneumatic actuatorRelated components and usage environment. Then decide which one to purchase based on one's financial capacity.Shanghai Fadeng Valve Co., LtdWelcome to your visit and purchase!
