Problems solved by technology
The power stroke of the gas-hydraulic booster cylinder is limiting the wider application of the gas-hydraulic booster cylinder
There are two main reasons for the small force stroke. On the one hand, due to the existence of the supercharging ratio, although the displacement of the supercharging piston is large, the displacement converted to the working piston is small; on the other hand, due to the movement of the supercharging piston, the supercharging The gas in the chamber must reach a certain gas pressure, which will cause a small pressure difference between the gas in the pressurized chamber and the gas source, and the gas flow rate will be small, resulting in a delay in starting and a long working cycle, which cannot achieve the characteristics of fast

The invention provides a four-piston gas-water pressure cylinder. Four pistons are arranged, a pop-up spring is additionally arranged at the rear end of the cylinder, so that displacement of the force stroke can be greatly increased under the same working periodic time, the application range of the gas-water pressure cylinder is enlarged, the flow speed of gas is greatly increased, the time of the force stroke is shortened, and energy is saved; a damping piston is additionally arranged so that pressure fluctuation of a high-pressure cavity can be effectively relieved, the working process is more stable and more reliable, and the product reliability is improved; and water is adopted as a liquid medium, the response of gas-water pressure cylinder is accelerated, pollution is avoided, and the application range of the gas-water pressure cylinder is greatly enlarged.
Description
technical field [0001] The invention relates to the field of hydraulic components, in particular to a four-piston air-water booster cylinder. Background technique [0002] Nowadays, with the rapid development of social modernization, many factories adopt assembly line production, making mass production possible. Pneumatic-hydraulic booster cylinder is an actuator that integrates the advantages of both hydraulic transmission and pneumatic transmission. It is used to drive the working mechanism of the machine to complete reciprocating motion and output force during the working stroke. The gas-hydraulic booster cylinder converts the compressed energy of the gas into the hydraulic energy and outputs the mechanical energy through the booster cylinder. Therefore, it not only has the advantages of clean and environmental protection, resource saving, fast response, convenient installation and maintenance, and low cost of pneumatic transmission, but also has the advantages of hydraul...
