Problems solved by technology
However, when the oil cylinder moves rapidly, there will inevitably be a large temperature rise in the cylinder body, which will cause the local temperature of the oil cylinder to be too high. If the temperature is too high, the aging of the seal will be accelerated, the sealing performance will be reduced, and leakage and seepage will occur later. The phenomenon of oil is difficult to remove, and it also reduces the service life of the oil cylinder
[0007] To sum up, although the existing technology solves the problem of slow reciprocating speed of the oil cylinder, it needs additional equipment to realize it, resulting in the entire hydraulic oil cylinder being too large in size and complicated in structure, making it difficult to use in a narrow space
In addition, the existing technology cannot realize the rapid output of the oil cylinder while controlling the temperature rise of the cylinder body

The invention relates to a hydraulic oil cylinder, in particular to a self-heat-dissipation rapid oil cylinder which solves the problems that in the prior art, a rapid hydraulic oil cylinder is complex in structure, not small enough in size and too high in temperature rise after working for a long time. The self-heat-dissipation rapid oil cylinder is provided with the double pistons and the cooling channel, self cooling can be achieved while the oil cylinder works efficiently, and the service life of the oil cylinder is long. In addition, the self-heat-dissipation rapid oil cylinder further has excellent sealing performance, and leakage cannot occur even if the self-heat-dissipation rapid oil cylinder works under high pressure. In general, the self-heat-dissipation rapid oil cylinder is reasonable in design, compact in size, low in energy consumption and simple in structure, has excellent stability and reliability, can achieve the effect of self-cooling the cylinder body while achieving rapid output, and meets the requirements of actual production.
Description
technical field [0001] The present disclosure relates to a hydraulic oil cylinder, in particular to a self-heating fast oil cylinder. Background technique [0002] In recent years, my country's hydraulic industry has experienced a process from imitation to independent research and development, from relying on imports to achieving self-sufficiency. The pressure inside the oil transmits power. With the rapid development of the overall industry, it has also embarked on the road of rapid development. Hydraulic cylinder is an executive element that converts hydraulic energy into mechanical energy in the hydraulic system. It is a special component for various coal mining machinery, construction machinery, special vehicles and large machinery. It plays an important role in industrial production. It can be used in forging machinery, Machine tools, injection molding machines, mining machinery, robots, machining centers and packaging machinery, etc. [0003] my country's hydraulic i...
