Problems solved by technology
[0002] Existing hydraulic cylinders mostly use oily media such as oil and emulsions as power fluids. Oily media are likely to cause environmental pollution. Especially in the mining industry, hydraulic cylinders for mining mostly use emulsions as media, and the emulsions are discharged into groundwater. Seriously affecting the water quality of groundwater, how to use tap water, natural water and other environmentally friendly media as hydraulic cylinder power fluid is an important issue; since hydraulic cylinders are mostly seamless steel structures, water media can easily lead to problems such as rusting of hydraulic cylinders. Environmentally friendly media has not been popularized, and it is only used in food, medical and other industries. It has the disadvantages of special treatment and high cost of water media.

Embodiment Construction
[0022] The technical solutions of the present invention will be further described in detail below through specific embodiments.
[0023] like Figure 1-3 As shown, a self-resilient multi-media environmentally friendly flexible hydraulic cylinder includes a flexible bladder 1, two end plates 2 and a spring assembly 3 connected between the two end plates 2. The flexible bladder 1 is a A columnar structure with openings at both ends, the two end plates 2 are sealed at both ends of the flexible bladder 1, and the end plates 2 are provided with a liquid port 4 that communicates with the flexible bladder 1. The liquid port 4 can be set as one, the inlet and outlet share one port, or can be set as two, one for liquid inlet and one for liquid outlet; the spring assembly 3 is arranged on the outside of the flexible bladder 1, and in a natural state, the spring The component 3 is in the shortest state, and the flexible bladder 1 is in a wrinkled and compressed state; liquid is passed i...

The invention provides a self-resilient multi-media environment-friendly flexible hydraulic cylinder, comprising a flexible bladder, two end plates and a spring assembly connected between the two end plates, wherein the flexible bladder is open at both ends. A columnar structure, the two end plates are sealed at both ends of the flexible bladder, the end plates are provided with a liquid through port that communicates with the flexible bladder, and the spring assembly is arranged on the flexible bladder On the outside, in a natural state, the spring assembly is in the shortest state, and the flexible bladder is in a folded and compressed state. The self-rebounding multi-media environment-friendly flexible hydraulic cylinder has the advantages of scientific design, compatibility with various media, low cost and suitable for large-scale popularization.
Description
technical field [0001] The invention relates to a hydraulic cylinder, in particular to a self-rebounding multi-medium environment-friendly flexible hydraulic cylinder. Background technique [0002] Existing hydraulic cylinders mostly use oil, emulsion and other oil-containing media as power fluids, and oily media can easily cause environmental pollution. Especially in the mining industry, mining hydraulic cylinders mostly use emulsion as the medium, and the emulsion is discharged to groundwater. It seriously affects the water quality of groundwater. How to use environmental protection media such as tap water and natural water as hydraulic cylinder power fluid is an important topic. Because hydraulic cylinders are mostly seamless steel structures, water media can easily cause problems such as rusting of hydraulic cylinders. Environmental protection media have not been popularized, only used in food, medical and other industries, and have disadvantages such as special treatmen...
