Characteristics of the hydraulic cylinder

With atomic energy, aerospace technology, the development of microelectronics technology, etc, the hydraulic cylinder technology developed in the field of deeper and wider. In addition to the successive development and emergence of new type hydraulic yuan, auxiliary parts, its application fields are also growing, such as the sun tracking system, elevators, high-rise building quakeproof system adopts hydraulic technology. In recent years, the hydraulic and modern mathematics, mechanics, microelectronics and computer technology together, make the hydraulic technology no matter in theory or in engineering application has entered a new stage of development. Hydraulic and pneumatic technology in China has roughly experienced the generic foreign products, design and development and the introduction of digestion and improve several stages of development. After years of development, hydraulic and pneumatic industry in China has formed a relatively complete product categories, research institutes, colleges and universities and the factory supporting relatively complete industrial system. With professional production as the goal, initially has formed the scale, hydraulic, pneumatic industry in China has a certain production capacity and technical level. , hydraulic cylinder speed characteristic, first of all, let's learn about what is the theory of benchmark rate. Theory reference speed, it is to point to in cylinder without external load, and assuming that the exhaust exhaust side for sound, air pressure is not very low, the calculation of cylinder speed is then called the theory of benchmark rate. General recognition of the maximum speed of cylinder without load for theory reference speed. But as the load increases, the maximum speed of cylinder will gradually decrease. The average speed of hydraulic cylinder, it is the ratio of the moving distance and the action time of the cylinder, it has to do with the relationship between the maximum velocity is: the maximum velocity to average velocity. Times. Generally speaking, the speed range of standard hydraulic cylinders, mm/s。 Speed is too small, can make the crawling phenomenon in a cylinder, but if the speed is too large, will speed up the process of wear parts, make the cylinder easy to leak, shorten its service life. As a result, too much or too little is bad, should choose the most appropriate, and within the prescribed scope. , the travel of hydraulic cylinder hydraulic cylinder stroke, the general is the use of cylinder and occasions, and stroke than about. If the installation of the cylinder form is different, so their trip than is also different, so should be kept separate, accurately determine the well.
