High-thrust and high-speed hydraulic cylinders: Hydraulic cylinders (cylinders for short) are commonly used components in hydraulic systems. They act as actuators in the hydraulic system. Other components such as pumps, valves, oil filter accessories, etc. are all specially designed for hydraulic cylinders. As a matter of fact, as the final executive mechanism of the hydraulic control system, the oil cylinder plays a very important role in mechanical equipment. The high-thrust high-speed hydraulic cylinder is characterized in that: the main body of the hydraulic cylinder is a sealed cavity arranged transversely, and a high-speed cylinder tube is coaxially extended and fixed at the front end of the hydraulic cylinder body, and the high-speed cylinder is coaxially installed in the high-speed cylinder tube. Cylinder special plug rod, a high-speed cylinder special plug is coaxially fixed at the end of the high-speed cylinder special plug rod, the high-speed special plug rod is coaxially sealed and sliding in the high-speed cylinder cylinder; the main body of the hydraulic cylinder is specially designed The internal partition is divided into an accumulator cavity and a supercharger cavity that are not connected to each other. An accumulator piston rod that penetrates the accumulator cavity and the booster cavity is coaxially installed in the main body of the hydraulic cylinder. The end of the accumulator piston rod at the front end of the gas cavity of the accumulator is fixedly equipped with an accumulator piston, which is installed in the accumulator cavity in a sealed and sliding manner. The accumulator piston is installed in the accumulator cavity. Separate the accumulator cavity into an accumulator gas cavity and an accumulator liquid body cavity; between the accumulator piston and the high-speed cylinder piston is the accumulator liquid body cavity; in the supercharger cavity The accumulator piston rod is coaxially equipped with a pressurizing cylinder piston. The pressurizing cylinder piston is sealed and slidingly installed in the turbocharger cavity. The booster cylinder piston is installed in the turbocharger cavity. It is divided into a supercharger with rod cavity and a supercharger without rod cavity. Cylinder diameter, rod diameter, and stroke should rely on national expert standards or other standards as much as possible, and avoid using non-standard sizes, otherwise it will increase processing difficulty and cost of manufacturing. Determine the length of the cylinder guide according to the length of the stroke. According to the working pressure or load, the strength of the cylinder, the plug rod, the screw, etc. is checked. At the same time, working pressure, ambient temperature, working medium, and operating speed are also the key to selecting seals. Different types of seals bear different pressures, temperatures, media, and speeds. Water-glycol media (HFC) cannot be sealed with polyurethane, but can only be sealed with rubber; when the oil cylinder runs fast, a slip ring type must be used. Seals, such as ster seal, grid ring, GD1000K, TDI, etc., Yx, U, V combined seals can be used when the running speed is slow; fluorine rubber seals are used in high temperature and high pressure environments; it must be considered when the running speed is fast Buffer sleeve, buffer valve. In addition, the material selection of parts must also be cautious.
