What is the difference between a single-acting cylinder and a double-acting cylinder?

There are many types of cylinders, which are divided into single-acting cylinders and double-acting cylinders according to their function forms. Compared with these two kinds of cylinders, there are some differences mainly in the force of cylinders. Single-acting cylinders can only be pushed out but not pulled back, and double-acting cylinders can do push-pull action. Single-acting cylinder and double-acting cylinder have their own advantages and different application fields, and the choice is mainly based on actual use and needs. Let's look at the difference between single-acting cylinder and double-acting cylinder. 1. What's the difference between a single-acting cylinder and a double-acting cylinder?

Cylinder is a mechanical device, which uses the energy of compressed air to generate force and motion in a straight line. According to the different action forms, it can be divided into single-acting cylinder and double-acting cylinder. So what's the difference between these two cylinders?

1, single-acting cylinder

The working principle of single-acting cylinder is to transmit hydraulic fluid or output force only in one direction. In the cylinder, the piston rod can be pushed outward, but not pulled backward, so it needs a force in the opposite direction to make the piston rod return to its original position. Traditionally, single-acting cylinders can be supplemented by auxiliary components, such as pumps, motors or internal springs. Because single-acting cylinders can only work in one direction, there are two kinds of single-acting cylinders in the market: pull type and push type.

2, double-acting cylinder

In contrast, double-acting cylinders provide greater complexity. Unlike single-acting hydraulic cylinders, they can transmit hydraulic fluid or output force in the direction of expansion and contraction. Ports are located at both ends of the cylinder, allowing the piston rod to move back and forth. This movement is caused by the replacement of the port, one end receives pressure, produces thrust and carries out push-pull movement.

Second, is the cylinder menu better or double action better?

When choosing a cylinder, it is a problem to consider whether it is single-acting or double-acting. Which is better, single-acting cylinder or double-acting cylinder?

1, single-acting cylinder is simpler than double-acting cylinder, with fewer parts and more convenient maintenance, which is its main advantage; Moreover, single-acting cylinders are usually smaller and more suitable for simple tasks-especially when rapid or controlled retraction is not required.

2. Although the structure of the double-acting cylinder is complicated, its accuracy is still not low. Moreover, because the double-acting cylinder has compressibility and extensibility, it does not need an external power supply, so it can meet the needs of larger industrial systems. Double-acting cylinder is also a better choice for projects requiring repetitive accuracy.

To sum up, single-acting cylinder and double-acting cylinder have their own advantages, and there is no better one. When selecting, the actual use and demand are mainly considered.
