Pneumatic and hydraulic pressure riveting machine difference

The working principle of pneumatic pressure riveting machine and hydraulic pressure riveting machine is basically the same, it is through the air pump or oil pump pressure gas (or oil) forced into the pipeline, forcing the executive element action. The difference is that the medium used is different: one is air, the other is hydraulic oil. But it is because of the different medium, caused by the two work performance is different, there are mainly the following points: 1, pneumatic environmental protection, clean, and hydraulic oil more. 2, work, pneumatic action fast, fast response, but also large vibration; Hydraulic action is slow but smooth. 3, hydraulic can produce large tonnage of equipment, and pneumatic is limited at this point. 4. In terms of construction and maintenance, hydraulic pressure is more complicated than pneumatic pressure, and of course the manufacturing cost is higher. 5, in speed regulation, hydraulic is easier to do than pneumatic.
