The author surveys the maintenance of rotary tillers and in the process, also found something wrong maintenance methods, Tiller, mainly in the following categories: 1, cooling air-cooled water. Some machine hand saw high temperature air-cooled machines, worry about damage to the machine, Tiller supply, with methods to help cool the water. In fact, it is very wrong approach, water suddenly cool, cylinder suddenly shrink, easy to pull the cylinder, broken rings, cylinder liners and even rupture. 2, do not pay attention to maintenance classes. Some machines do first hand that the maintenance days on the line, in fact, wear a cumulative process, as the main maintenance classes. 3, does not pay attention to the quality of fuel and lubricants. Poor fuel quality, not only the power of the machine is not enough, Tiller orders, and accelerated wear of the pump and the core sets; lubricants directly affect the performance and life of the machine to start, do not be sloppy. Yichang City, the village of Shahe Township 卢其兵 yaowan reflect his machine has been used for good, because when there is a lack of jobs lubricant, plus a renewable oil, machine performance results overall decline, last overhauled to solve problems. 4, an engine partial cover pad improper use sealant. Partial cover cushion after use sealant, the excess glue with easy access to the gear box, because the long hours of work and suction pump, oil sealant is easy to plug into the hole, the crankshaft and connecting rod can not be effectively lubricated. 5, the fuel tank cap oil leak sealed with a thin film of paper. After the sealed tank, long Dezhou Aage Ruijin Agricultural Machinery Co., Tiller maintenance, East Development Zone is located in Texas. Location and convenient transportation, is set agricultural machinery product development, manufacturing and sales of businesses. Mainly in the production of rotary tillers, pastoral management, floating corn planter, corn planter link, corn peeling machine, peanut harvesters, farm-based fight drugs, 20-year history of mechanical processing, the company occupies 70,000 square meters, more than 100 employees, of which 10% 5 senior, various management personnel of the total, 70% of the total number of professional and technical personnel, fixed assets of 15 million yuan, more than 180 sets of major equipment, It has an annual production capacity of 50,000 sets of production and sales growth year after year. Tiller orders, Aage Ruijin agricultural machinery (online consultation), Tiller provided by the Texas Agricultural Machinery Co., Ltd. Aage Ruijin. Texas Agricultural Machinery Co., Ltd. Ruijin Auger (www.agrjnongji.com) Shandong Dezhou, agricultural machinery leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Auger Ruijin agricultural machinery leadership with the staff warmly welcome all inquiries negotiations to create Ogg Ruijin agricultural machinery better future.
