Do you know the difference between FESTO cylinders and electric actuators?

What are the differences and connections between FESTO cylinders and electric actuators? Why raise this question? It's because we are all concerned about this issue, and sometimes the two are briefly mixed together. Therefore, the editor deliberately explains it so that we can have a clear understanding. And on the website, we not only need to understand the common knowledge of hydraulic cylinder types and principles.

FESTO cylinder can be used in harsh environments, is skilled in reciprocating linear motion, and has the characteristics of simple and convenient operation without the need for protection. But if you want to achieve high precision, then the cylinder is difficult to achieve.

Electric actuators are mainly used in rotating and swinging conditions. Its advantage is its fast response speed, and through the feedback system, it can accurately control the direction and speed. However, its structure is relatively complex and requires high demands on the operator.

Each of these two aspects will be summarized and explained in detail below.

FESTO cylinder:

(1) The requirements for operators are relatively low due to its simple structure and easy operation of device protection;

(2) The output force of a cylinder is proportional to the square of the cylinder diameter, so the output force is relatively large;

(3) It has a strong habit of adapting to various environments due to its ability to prevent dust and water.

FESTO cylinders include:

(1) Capable of stopping in multiple directions with high control accuracy, up to 0.05 millimeters;

(2) Flexibility can be adjusted and moved as needed to a certain extent, and accurate control can be achieved in terms of motor speed and positioning.

What are the common and main types of cylinders in specific classifications? What are the important load-bearing components in a cylinder? And, what else do we need to know and understand about cylinders? The main purpose of raising these questions is to introduce the content of the article and prepare everyone for targeted learning, thereby improving their learning efficiency and effectiveness.

What are the common and main classifications of cylinders?

For the classification of cylinders, the following three are commonly used, specifically:

If divided by cylinder diameter, cylinders can be classified into four types: micro cylinders, small cylinders, medium cylinders, and large cylinders.

If divided by buffering form, then cylinders can be divided into three types: non buffering cylinders, cushion buffering cylinders, and gas buffering cylinders.

If divided by size, then cylinders can be divided into two types: space saving type and standard type.

What are the important load-bearing components in the cylinder?

In FESTO cylinders, the important load-bearing component is mainly the piston rod, which cannot be ignored. In terms of material, it is usually made of high carbon steel or stainless steel, and the surface is treated with hard chrome plating. In addition, sealing and wear resistance are required on the sealing ring.

What are dynamic seals and static seals in a cylinder? How to distinguish?

The dynamic seal in a cylinder refers to the seal on the rotating or reciprocating parts, while the static seal refers to the seal on the stationary part of the cylinder. Moreover, the above are also the distinguishing criteria for these two sealing forms, which are informative.

What are the specific reasons for cylinder deformation in the clearance?

The specific reason for the deformation of FESTO cylinder in the clearance is as follows:

Due to various reasons or related factors, such as technical reasons, changes have occurred in the expansion gap of the cylinder, cylinder partition, partition sleeve, and gland sleeve, making them unsuitable. Therefore, when the cylinder moves, deformation occurs due to the expansion force.

In the process of customizing cylinders, many customers may ask about the durability of the customized cylinder. The longevity of the cylinder is closely related to its quality, operating environment, and frequency of use. Below, we will introduce how to improve the durability of customized cylinders?

1. For special environments. For example, in high-temperature environments between 100-180 ° C, both custom-made cylinders and standard cylinder components require high-temperature resistant sealing rings and lubricating oil.

2. Use wear-resistant sealing rings. The durability of a cylinder mainly depends on whether the sealing ring is wear-resistant. It is matched with the same sealing ring supplier from Yadeke and SMC, with a unique sealing design that reduces friction resistance and makes the sealing ring more durable.

3. Adopting bronze wear-resistant tape. Bronze wear-resistant belts have longer durability than ordinary rubber wear-resistant belts, and are made of polymer materials, doubling their service life.

4. Use oil containing copper sleeve. The combination of oil containing copper sleeve and shaft sealing ring is more dust-proof, effectively blocking dust in the environment and improving service life.
