It is understood that in June this year, Yongji Motor Factory received an order to export 129 sets of oilfield motors from North America to the whole country. The oilfield motor that was exported all this time is the AC variable frequency oilfield motor developed by the company after 8 years of independent innovation, representing the level of research and development in China's AC and DC oil field.
The oil rig is a very complex and large-scale complete set of equipment for land oil, natural gas drilling, desert, ocean and other areas. It is technically difficult and expensive. The oil rig transmission mode is a sign of the technical level and advanced level of the rig. The drive is currently the most advanced drive. The United States is the most powerful country in the manufacture of complete sets of oil rigs. China is one of the few countries that manufacture complete sets of oil rigs.
Since China's oilfield drilling rig drive system has changed from mechanical transmission to electric transmission, the motor used has been monopolized by world famous foreign brands. In 1998, Yongji Motor Factory, which is the leader of the domestic locomotive traction electric drive development enterprise, entered the oilfield motor market relying on independent innovation of advanced motor manufacturing technology, which filled the gap of China's oilfield drilling motor.
The YZ08 series DC motor developed in the following year adopts internationally advanced motor manufacturing technology and advanced insulation structure. It has good versatility, maintenance-free, high efficiency, high reliability, and its external installation dimensions are the same as those of foreign DC drilling motors. Replacing the characteristics of imported drilling motors, etc., replacing more than 70% of imported electric motors in domestic oilfields, thus ending the history of most of China's oilfield drilling motors relying on imports.
Crawler Excavator range from 1.8 ton to 45 ton excavators, including 0.8 ton, 1 ton, 1.2 ton, 1.5 ton, 1.8 ton, 3 ton, 5 ton, 6 Ton ,7 ton 13 ton, 15 ton, 20 ton, 21 ton 22 ton, 30 ton, 33 ton, 38 ton, 40 Ton, 46 Ton.
The main components of the excavators all bought from famous company, the engine from Cummins, the hydraulic system form Linde, the Chassis from Shantui.
There are many kinds of bucket for optional, standard bucket, rock buck, mud bucket and etc.
The main technology was inherited from Japan.
