Introduction to the working principle of the British NORGREN cylinder

Norgren Norgren is a world-renowned manufacturer and supplier of pneumatic products, providing pneumatic and fluid control solutions to customers worldwide. Through a selection of dealer networks and an international network of more than 16,000 employees in 26 countries around the world, Nuoguan produces and supplies a full range of pneumatic control and automation products, all of which hold ISO9001 quality standard certificates. It ensures that customers can purchase the pneumatic products they need from the trusted supplier of Norgren. At the same time, Nuoguan designs and produces tens of thousands of special products every year to meet the specific requirements of customers. Companies in 26 countries can provide customers with sales including pneumatic control circuit design, pneumatic technology and product problems. Technical advice, dedicated application guidance, technical support at all levels, and production and processing of conventional products locally. The 2006 Norgren Group's sales growth rate was 13%, accounting for 37% of the IMI Group, while Norgren China's sales growth rate was 22%. The pneumatic actuator converts the pressure energy of the compressed gas into a pneumatic actuator of mechanical energy. The cylinder has two types of reciprocating linear motion and reciprocating oscillation (see figure). The cylinders for reciprocating linear motion can be divided into four types: single acting, double acting, diaphragm type and impact cylinder.

1 Single-acting cylinder: only one end has a piston rod, which supplies air from one side of the piston, outputs force in one direction, and returns by spring or self-weight.
2 double-acting cylinder: alternately supply air from both sides of the piston, outputting force in one or two directions.
3 Diaphragm cylinder: replace the piston with a diaphragm, output the force in only one direction, and reset with a spring. Its sealing performance is good, but the stroke is short.
4 Impact cylinder: This is a new type of component. It converts the pressure energy of the compressed gas into the kinetic energy of the high-speed (10-20 m/s) movement of the piston. The impact cylinder adds a middle cover with a spout and a drain. The middle cover and the piston divide the cylinder into three chambers: a gas storage chamber, a head chamber and a tail chamber. It is widely used in a variety of operations such as blanking, punching, crushing and forming. The cylinder that reciprocates is called the swinging cylinder, and the inner chamber is divided into two by the vane, and the air is alternately supplied to the two chambers, and the output shaft is oscillated, and the swing angle is less than 280. In addition, there are rotary cylinders, gas-liquid damping cylinders and stepping cylinders.

NORGREN NOOREN includes pneumatic equipment and pneumatic components, cylinders, rodless cylinders, solenoid valves, control valves, machine control valves, valve guides, filters, regulating valves, joints and other products (UK).
Determine the thrust and tension on the piston rod based on the amount of force required for the job. Therefore, when selecting the cylinder, the output force of the cylinder should be slightly margined. If the cylinder diameter is small, the output force is not enough, and the cylinder can not work normally; but the cylinder diameter is too large, which not only makes the equipment cumbersome, high cost, but also increases the air consumption, resulting in waste of energy. When designing the fixture, force-increasing mechanisms should be used as much as possible to reduce the size of the cylinder.
The double-acting cylinder refers to a cylinder in which two chambers can respectively input compressed air to realize two-way movement. Its structure can be divided into double piston rod type, single piston rod type, double piston type, buffer type and non-buffer type. These cylinders are the most widely used.
Double piston rod double acting cylinder Double piston rod cylinder has two kinds of cylinder fixing and piston rod fixing.
When the cylinder is fixed, the load (such as the workbench) is integrated with the two piston rods of the cylinder, and the compressed air enters the two chambers of the cylinder in turn (one chamber is exhausted and the other chamber is exhausted), and the piston rod drives the table to move left and right. The range of motion of the table is equal to three times the effective stroke s. The installation takes up a lot of space and is generally used on small devices.
When the piston rod is fixed, the pipeline connection is convenient, the piston rod is made hollow, the cylinder body is integrated with the load (table), and the compressed air enters the two chambers of the cylinder from the left end or the right end of the hollow piston rod, so that the cylinder body drives the worktable. Moving to the left or left, the motion range of the table is twice that of its effective stroke s. Suitable for medium and large equipment.
