Electric push rod marks China's construction machinery research and development level into a new height

(Summary description)The electric push pole market is also a restricted point for the development of strategic emerging industries in China, which is determined by the characteristics of high-end manufacturing industry. First, the product has high interest, such as the cost of solar power generation is 34 times the conventional thermal power; Second, high requirements for service facilities, such as new energy vehicles if there is no corresponding charging facilities, the car can not run; Third, the market trust bottleneck, that is, after the new domestic things into, consumers do not trust.

The electric push-rod cantilever crane has preliminarily formed a research and development and manufacturing system of main engine products, basic technology and functional components with international frontier level. China's equipment manufacturing industry should focus on industrial optimization and upgrading, shift from a production-oriented to a service-oriented one, consolidate its industrial foundation, solve the problem of backward development of basic parts and components, cultivate emerging industries, and enhance its capacity for independent innovation. The concept of "from big to strong" in the development of China's high-end equipment manufacturing industry, at the same time, China's construction machinery industry can only play the cluster effect and brand effect, to find a unique way of internationalization. It indicates that the intellectual property barriers of foreign leading enterprises in the field of lifting machinery have been gradually conquered by China's independent intellectual property rights. Domestic construction machinery enterprises have broken the foreign monopoly of 3000T crawler cranes, and domestic super-tonnage crawler cranes have come out one after another. Standing at the forefront of the global crane industry, it also marks that China's construction machinery research and development level has entered a new height.







The electric push rod takes the motor as the power source, and through the forward rotation of the motor, makes the hydraulic oil output pressure oil through the two-way gear pump, and sends it to the working cylinder through the oil circuit integration block, so as to realize the reciprocating movement of the piston rod. When the electric push rod works, if the external force on the piston rod exceeds the rated output force or the piston has reached the end point, the motor is still rotating, then the oil pressure in the oil circuit increases to the set pressure, the overflow valve quickly and accurately overflow, to achieve automatic overload protection. The motor is running, but it never burns out. The pressure self-locking mechanism is designed in the oil circuit integration block of the electric push rod. When the motor stops rotating, the piston rod immediately stays in a certain position and the pressure oil is in the state of maintaining pressure. The electric putter can have various structural forms according to the site installation space and users' usage. For details, please refer to the outline size diagram of the electric putter or customize the style according to users' requirements. The motor drives the positive and negative output pressure oil of the two-way hydraulic pump through the positive and negative rotation, and sends it to the cylinder through the hydraulic control valve, which also realizes the reciprocating movement of the piston rod.

What are the gaps in the production technology of small electric putter manufacturers

450/5000 Most of the small electric push rod manufacturers in China are formed by the disintegration of large state-owned enterprises, the restructuring of small and medium-sized enterprises and the development of individual enterprises, so the overall level of development is low and there is no uniform standard, but the development prospect of the whole industry is good. The current situation of small electric push rod manufacturers is similar products, low technology content, resulting in weak market competitiveness. With the speeding up of economic, our opportunity came also, as an enterprise, we should be on the market for segmentation, positioning, choose suitable service object, it is important for electric push rod products further deepening, the pursuit of differentiation, so that each enterprise has a clear target market, and form their own features.

Electric push lever technical level gap, first of all in the product structure, hydraulic, pneumatic, sealing and other components are mainly introduced technology or tracking imitation. Secondly, in terms of technological development, due to its own weak ability of scientific research transformation, imported products occupy the majority of the market.

Electric hydraulic push rod preferred Mars electromechanical

In 1942, the United States took a laboratory of The Massachusetts Institute of Technology as the center, electric push rod to make a thorough investigation and research on the reliability of the main component of electronic equipment failure vacuum tube. In 1950, the United States established the Department of Defense Electronic Equipment Reliability Task Force of the United States Army, Army and Air Force. In 1952, the Task Force published a report with 17 recommendations on reliability and renamed the Task Force the Department of Defense Electronic Equipment Reliability Advisory Group (AGREE). In 1998, the Japanese Association for Science and Technology established the Reliability Research Committee. In 1962, the journal "Reliability Center" was established in France by the National Institute of Communications for electric putter. In 1965, the International Electrotechnical Commission (IEc) established the Reliability Technical Committee redundancy 56 and held the first academic symposium on electronic product reliability in Tokyo, which unified the national reliability terminology and formulated the standards. ] In 1998, the second symposium on electronic product reliability was held in Budapest. The reliability research in China began in the late 1950s, when the Fourth Ministry of Mechanical Industry established the Reliability Research Institute in Guangzhou. By the 1960s, the Ministry of The Seventh Machinery Industry had also established relevant research institutes. In 1975, the Institute of Applied Mathematics of the Chinese Academy of Sciences held a "Discussion Class on Reliable Mathematics". In 1979, the Institute of Reliability and Quality Management was established by the China Society of Electronics. In 1980, after the national Academic exchange on reliability, many institutions of higher learning offered courses on reliability theory and government use, and carried out research in this field, mainly focusing on the reliability research of electronic products and electronic equipment.

This paper introduces the transmission mechanism and working requirements of electro-hydraulic push rod

Electric hydraulic push rod is a set of machine, electricity, liquid as one of the hydraulic drive manipulator, suitable for the need to reciprocate push and pull straight motion, can also be used to need to rise, fall or clamp the work place, and can realize the remote dangerous area of centralized or automatic control. Electro-hydraulic push rod is a new flexible transmission mechanism integrating machine, electricity and liquid, which is composed of actuator (oil cylinder), control mechanism (hydraulic control valve group) and power source (oil pump motor and so on). The electro-hydraulic putter can have various structural forms according to the site installation space and users' usage (see the outline size diagram of the electro-hydraulic putter for details, or customize the style according to users' requirements). The motor drives the positive and negative output pressure oil of the two-way hydraulic pump through the positive and negative rotation, and sends it to the cylinder through the hydraulic control valve, which also realizes the reciprocating movement of the piston rod. Features of electro-hydraulic push rod: 1. Compact structure, convenient installation, small space occupation and simple maintenance. 2. It can be started with load and has overload protection function. 3. Two-way hydraulic lock is set in the loop, which can stop at any position within the specified travel range and self-lock, and keep the output force unchanged. 4. Push and pull, speed (user requirements) stepless adjustable, wide driving range. 5. Power off for some reason, push rod locks itself to avoid accidents. 6. Full hydraulic transmission, sensitive action, stable operation, buffering external impact force, stroke control ≥0.5mm.
