Electro-hydraulic proportional control technology applications in engineering in engineering drill rig production, drilling rig how to automate production control, depending on one gate technology, this technology is the electro-hydraulic proportional technology, mechanical engineering technology as a proportion electrophoresis system interfaces, control engineering rig automated production. Drilling rig used after control technology to achieve a good electro-hydraulic proportional system simplifies production of complex process control, thereby reducing production costs, improve quality control process engineering rig XY-2 type drilling rig, improve production reliability, Rig shortened working cycle time. Electro-hydraulic proportional technology applications engineering drill, is more conducive to automated drilling rig, efficient, intelligent development, but also to improve production efficiency and control performance engineering rig, has an important value, which is electro-hydraulic Proportional technology existence. Drilling rig water cooling mechanism mainly including: through water equipment, the output shaft axis of the cavity, sealing devices, water faucets and copper device includes elbow XY-2 type drilling rig picture, copper elbow connected with a tap, the other end is inserted from the rear end of the output shaft to the output shaft axis of the chamber, sealing means disposed between the output shaft and copper bend XY-2 type drilling rig much money, the sealing device not only can play the role of seals, but also can play to support the role of copper bends, which is important for the sealing means. It is due to these effects, to ensure that the advantages of drilling rig equipment, drilling rig it with traditional engineering equipment differ, allowing cooling water directly into the output shaft from the rear end, relying on pressure ejected from the front, ring the pressure on smaller XY-2 type drilling rig prices, thereby reducing the sealing ring, the sealing effect also would be better cooling efficiency drilling rig also will be better. XY-2 type drilling rig production line _ City of XY-2 type drilling rig _ Prius Prius provided by Luoyang Drilling Equipment Co., Ltd. Luoyang Prius Drilling Equipment Co., Ltd. (www.zuanji888.com/) strong, credible, Luoyang in Henan and other industry-specific equipment industry has accumulated a large number of loyal customers.
