Industry dilemma: Hydraulic pollution into efficiency "stumbling block" The hydraulic system of agricultural machinery as the core of power transmission, its stability directly affects the efficiency of operation. According to the China Agricultural Machinery Industry Association survey data in 2023, more than 60% of agricultural machinery failures stem from hydraulic oil pollution - impurities, metal particles and water erosion lead to valve stagnation, pump body wear, not only shorten the life of the equipment by 30%, but also cause annual maintenance costs of more than 10,000 yuan. The traditional filter is difficult to meet the needs of high-precision agricultural equipment because of its low filtration accuracy and poor compression resistance.
Technological breakthrough: Liffelt's "Triple Filter System" reshaping standard In response to industry pain points, the Liffelt R & D team has spent three years to overcome the problems of materials science and fluid dynamics and launched the LFT-HPF series of high-pressure pipeline filters. This series of products uses a "triple filtration system" - initial effect interception, precision screening and magnetic adsorption purification, can intercept ≥1 micron impurities, filtration efficiency of 99.8%. The core components are made of high temperature resistant stainless steel with a maximum pressure of 42MPa, which can adapt to extreme environments ranging from -40 ° C to 120 ° C and effectively resist the oil impact in high-intensity operation scenarios of agricultural machinery. "We do away with the single filtration mode and ensure that the hydraulic oil is always' sterile 'through' gradient purification '." According to Wang Peng, technical director of Liffert, the intelligent differential pressure monitoring device built into the filter can warn the pollution level in real time, and with the modular design, the replacement time of the filter element is reduced to 1/3 of the traditional products, greatly reducing the cost of downtime and maintenance.
At present, the LFT-HPF series has been applied to a number of domestic agricultural machinery leading enterprises. After a large harvester manufacturer in Shandong assembled the filter, the equipment failure rate was reduced by 87%, and the annual maintenance cost was reduced by 150,000 yuan; Xinjiang cotton picking machinery customer feedback, the filter extended the life of the hydraulic pump to 4000 hours, work efficiency increased by 12%. "I used to have to change the filter every half month, but now I don't have to worry about it for three months, which saves a lot of cost." Master Li, the person in charge of Heilongjiang agricultural machinery Cooperative, praised the effect of use.
Ecological layout: From pieces to system solutions Liffert does not stop at hardware innovation. The company launched the "agricultural machinery hydraulic health management platform" simultaneously, and connected the filter data to the cloud through the Internet of Things module to provide value-added services such as oil pollution analysis and maintenance cycle prediction. This move marks the transformation of the enterprise from a single equipment supplier to an "intelligent operation and maintenance service provider", and the construction of a full chain security system for the industry
Zhang Ming, a professor at the College of Mechanical Engineering of China Agricultural University, believes that Lifelter's technological breakthrough not only solves the current problem, but also promotes the standardization process of the agricultural machinery industry. "The popularity of high-precision filters will force the upgrading of hydraulic oil products, thereby raising the technical threshold of the entire industrial chain." He suggested that relevant departments should speed up the development of pollution control specifications for agricultural machinery hydraulic systems to form a virtuous cycle of technological iteration.
Liu Qiang, general manager of Lifeldt, said that the company will continue to invest in research and development, explore the application of AI algorithms in pollution prediction, and plan to introduce biodegradable material filters to reduce environmental protection costs. At the same time, the company is negotiating technical cooperation with the European Agricultural Machinery Association to accelerate the globalization layout. As agricultural mechanization moves toward the goal of "high efficiency, low loss and long life", Lifelter's practice of reshaping the industry ecology with technological innovation not only provides replicable solutions for agricultural machinery processing enterprises, but also highlights the breakthrough ability of Chinese manufacturing in the field of segmentation. In the future, this "filtering revolution" may trigger a wave of systematic upgrading of the agricultural machinery industry.
