Electric cylinder is an electric actuation system with high precision, high integration, strong environmental adaptability, and light pollution. The electric cylinder motor drives the screw to rotate through transmission mechanisms such as synchronous pulleys, gears, and worm gears. It has the characteristics of flexible coordination, easy installation, simple setting, and convenient use. In addition, it has high strength, small return clearance, long service life, good control performance, high control accuracy, and low maintenance cost.

Our company has been committed to the research and development of heavy-duty, large stroke, and high environmental adaptability electric cylinders for many years. Our products and technologies are in a leading position in the industry, with independent intellectual property rights. Our products can achieve integrated research and development, production, and sales. Our customers are in the fields of aerospace, naval ships, university testing equipment, engineering vehicles, petrochemicals, etc., and can complete large load operations in extremely harsh environments. At present, the company has completed the delivery of products with a maximum load of 120T, a maximum stroke of 6m, a working temperature of -45 ℃~+120 ℃, and a protection level of IP67, which have received high customer evaluations.

Our company's products mainly have the following two key technologies:

Key Technology 1: Research and Engineering Technology for High Load, Long Life Electric Cylinders

Based on the rapidly growing demand in the company's heavy-duty electric cylinder market, as well as the requirements of users for short production cycles, high reliability, and long service life in electric cylinder products, the company takes the opportunity of deep development of "military civilian integration", takes the market as the driving force, and technology as the support to enhance the core competitiveness of the enterprise. Adhering to the product development policy of "increasing load, strengthening system integration, refining commonality, and making individuality unique", the company innovates the technology of heavy-duty planetary roller screw pairs around the demand for heavy-duty high thrust.

Based on the above key technologies, our company's heavy-duty electric cylinder is more conducive to the takeoff and landing conditions of large construction vehicles, and can completely replace traditional hydraulic cylinders in terms of functionality and performance.

Key Technology 2: Design and Application Technology of Servo Controller for Heavy duty Electric Cylinder

Our independently developed servo controller for heavy-duty electric cylinders is mainly used for high-precision positioning control of heavy-duty electric cylinders. Our company has years of theoretical foundation and production experience in heavy-duty electric cylinders and servo control systems. Throughout the entire manufacturing process, we have meticulously designed, produced, and debugged our products. The mature experience accumulated in the field of heavy-duty electric cylinders and control supports our company's current design and production capabilities for servo controllers for heavy-duty electric cylinders. Compared with other companies, our company has significant advantages in the design capability and engineering of heavy-duty electric cylinders and control systems, ensuring high-precision position control. In the process of implementing servo control strategies and heavy-duty electric cylinders, our company has more mature design and engineering experience compared to other manufacturers.

In summary, the research and mass production of oil extraction equipment is undoubtedly a necessary means to enhance oil development in the future, with broad market prospects.

There are two types of oil extraction methods: self jetting oil extraction and mechanical oil extraction. Currently, mechanical oil extraction is the main method of oil extraction in China.

A pumping unit is a type of equipment used for extracting oil, commonly known as a "kowtow machine", which uses pressure to extract oil from a well.

The pneumatic balance beam pumping unit utilizes the compressibility of gas to store and release energy to achieve balance, and can be used for heavy-duty pumping units weighing over 10 tons. This balancing method reduces the dynamic load and vibration of the pumping unit, but it requires high precision and complex processing. The working principle of a pneumatic pumping unit is to convert the compression energy of gas into mechanical energy for up and down reciprocating motion through a cylinder. The pneumatic piston rod is connected to the pumping rod to drive the downhole pumping pump to complete the pumping work.

From the analysis of product structure, among the various types of pumping units developed in China, the beam type vertical shaft pumping unit oil extraction system accounts for a large proportion, with the most varieties and the fastest technological development. It has achieved good results in practice and has become the mainstream and direction of pumping unit development in China.

Pumping unit is a commonly used ground lifting equipment in oilfield production. Currently, there are over one million mechanical oil wells worldwide, of which over 900000 are pumping unit wells, and the number is increasing year by year. Since the 1980s, China has achieved full localization of its pumping units, which not only meet self-sufficiency requirements but also have some exports. A number of large-scale pumping unit production enterprises have been formed, including Changqing Machinery Manufacturing General Factory, Shengli Oilfield Gaoyuan Petroleum Equipment Company, Daqing Oilfield Lishen Pump Industry Co., Ltd., Shandong Binzhou Jiuhuan Petroleum Machinery Co., Ltd., Shengli Oilfield Furuite Petroleum Equipment Co., Ltd., Puyang Zhongshi Group Co., Ltd., Hebei Huayou Yiji Pumping Unit Co., Ltd. Monitoring data shows that in 2009, China's pumping unit production capacity reached around 25000 sets, but actual production was less than 20000 sets, resulting in severe overcapacity.

The target consumer groups for oil field pumping units in China are very clear, mainly PetroChina and Sinopec. The production enterprises of various oil fields under the jurisdiction of CNOOC and foreign oil companies. For the domestic market, the main major clients are group companies such as PetroChina or higher-level regional holding companies, and some trading companies also have important customer characteristics as purchasers.
