China Construction Machinery Information

a mining company in Anhui mainly has three mining areas: Lilou, Wuji and MCC, with reserves of 325 million tons and an annual output of 5 million tons. It is the largest underground mining area in China, and its main business is iron ore mining. The main equipment of the company is 12 simba-h1354 mining and drilling jumbos produced by Atlas Copco, Sweden, and 12 14 ton lh514e six cubic electric LHD produced by Sandvik, Sweden

moreover, the standard block used for the main calibration of the hardness tester of the hydraulic system of mining and drilling jumbos and electric LHD and other equipment of the company cannot be used on both sides, and the plunger pump should be used. The working conditions are characterized by high temperature, high pressure (heavy load), much dust, etc

at the beginning of 2017, the company reported that it had recently purchased 104 barrels of Great Wall Puli L and adopted the "granular fire barrier" technology -hm68 anti-wear hydraulic oil (ordinary) to replace a brand of hydraulic oil. It was found that a small brand of hydraulic oil was too thin in viscosity under high temperature and high pressure, the oil pressure could not be hit, and the anti emulsification effect was poor. On January 17, we went to the company for the first time for technical services. According to the working conditions of the on-site equipment, our technicians recommended the use of Great Wall Zhuoli l-hm68 anti-wear hydraulic oil (high pressure) and even ae68 hydraulic oil products. Both parties agreed to ensure the supply of Great Wall Zhuoli l-hm68 anti-wear hydraulic oil (high pressure) before the Spring Festival. After nearly four months of use, customers reported that the use effect was good

at the beginning of May 2017, the company also reported that it had recently purchased more than 300 barrels of Great Wall Zhuoli l-hm68 anti-wear hydraulic oil (high pressure), and found that the oil was still too thin under high temperature and high pressure, the oil pressure could not be hit, and the anti emulsification effect was poor. On May 16, we carried out technical services to the company again. According to the working conditions of the on-site equipment, our technicians recommended the use of great wall ae68 hydraulic oil products. Both parties agreed to select ae68 hydraulic oil medium barrels for trial use in the near future, and compare them with the current oil in use, so as to lay a solid foundation for the promotion and application of ae68 hydraulic oil in the company in the later stage

at the beginning of July of the same year, the company purchased 870 barrels of ae68 hydraulic oil for trial use. After nearly three months of trial comparison, customers reported that although ae68 hydraulic oil is light in color and still feels thin at room temperature, it has good viscosity retention under high temperature and high pressure, and the anti emulsification effect has also been significantly improved. It will be further promoted in the future

at the beginning of December 2017, the company once again reported that the oil felt thin, and the oil in use was mixed, and the anti emulsification effect was poor. On December 11, we carried out technical services for the third time. Our technicians first explained the base oil used in ae68 hydraulic oil to the customer, dispelling the customer's doubts about sports equipment that the oil feels thin, and then went to the site under the Lilou mine to understand the working condition of the equipment. According to the on-site working conditions, it is preliminarily analyzed that the main reasons for the above situation are the high underground humidity and the dusty environment. Then, the oil samples in use were collected on site, the causes were further found through analysis and detection, and an information feedback letter to the customer was issued, emphasizing the importance of doing a good job in on-site lubrication management, which was recognized by the customer

through our unremitting efforts in the past two years, the company purchased 570 tons of Great Wall lubricating oil in 2018, including 70 tons of vehicle oil and 500 tons of industrial oil (including 34 tons of ae68), and the share of Great Wall lubricating oil reached more than 90%
