What are the sample size drawings and accessories of QGB and QGA cylinder model parameters?

Regarding the QGB cylinder and QGA cylinder model parameters, sample dimensions, drawings and accessories, the editor of Shenwei will explain it to you here:

"QGB cylinder and QGA cylinder" are national standard products, and their materials are made of cast iron. It is widely used in Guangdong and Wuxi. The development trend of QGB cylinders is a development opportunity for domestic enterprises. However, the domestic valve industry should realize that the export volume of automated valves is less than 5% of the total output value, while the import volume is equivalent to the total output value. This shows that my country's demand for automated valves The demand gap is still not small, and there is still a big gap between products and foreign countries in terms of technology and quality, and they cannot fully meet the needs of the domestic high-end market. Cylinder companies must firmly seize this opportunity for the development of automated cylinders to improve market share and product quality.



The characteristics of QGB cylinder and QGA cylinder are as follows:
1. The front and rear end covers of cylinders with a bore diameter of 32-100mm are made of aluminum alloy, and the cylinder barrel is a precision aluminum tube with a hard anodized inner wall.
2. The front and rear end covers of cylinders with a bore diameter of 125-400mm are made of cast iron, and the inner wall of the cylinder barrel is made of precision seamless steel tubes that have been hard anodized and then plated with hard chromium.
3. Working pressure: 0.15～0.8mpa
4. Pressure resistance: 1.2mpa
5. Operating temperature range: -25～+80 (℃) (but under non-freezing conditions)
6. Working medium: purified compressed air containing oil mist

QGB cylinder and QGA cylinder model parameter sample size diagram is as follows:


How do we choose a cylinder? Then let the editor of Shenwei tell you:
1. Determine the cylinder inner diameter
1. Determine the axial load thrust of the cylinder according to the actual load status of the required cylinder
2. Determine the working pressure of the cylinder according to the air supply conditions.

2. Determine the cylinder stroke
The cylinder stroke is preselected based on the cylinder operating distance and the stroke ratio of the transmission mechanism. To facilitate installation and debugging, an appropriate margin should be left in the calculated stroke.
Standard strokes should be used as much as possible to ensure delivery speed and reduce costs.

3. Determine the cylinder category
The type of cylinder is selected according to the specific requirements for the use of the cylinder and its installation requirements.

4. Select the buffer form of the cylinder
Our company's cylinders are equipped with different buffer devices. Users should choose according to the actual load movement state when choosing. If the load is at a large speed, it is difficult to absorb the balance shock capacity only by the buffer of the cylinder itself, so the buffer must be designed. Balancing circuit or design using external snubbers to soften shock.

5. Determine whether the cylinder is magnetic
According to the actual situation, determine whether the cylinder has a magnet and select the corresponding induction switch.

6. Select the installation method of the cylinder
Choose the installation method of the cylinder according to its installation requirements.

7. Select the cylinder piston rod connection method
After the cylinder is pre-selected, it is necessary to check the stability of the cylinder's piston rod (especially when it is slender and large) according to its different placement methods;and to check the air consumption of the cylinder under actual use conditions.
