Hydraulic system to improve the degree of automation engineering drill rig technology and electronic engineering technology combines PLC, then it can be very good to improve the degree of automation engineering rig, drilling rig more effectively improve production efficiency. Drilling rig used in the hydraulic system for the feed mechanism, feed mechanism hydraulic system uses electro-hydraulic proportional control valve meter-speed circuit, when the system pressure by the electro-hydraulic proportional relief valve according to the actual conditions regulator 100 Rig how much money, to try by the electro-hydraulic proportional control valve to adjust the rig used in the project-based electro-hydraulic proportional control technology, control strategies and methods of analysis Rig hydraulic system, the application of electro-hydraulic proportional control technology achieve drilling rig automation. Drilling rig spud before what kind of work you want to (1) drilling rig spud before checking various machinery equipment in good condition, the adequacy of preparation mud, water and electricity pipes is smooth, in order to ensure normal. (2) before the official first start drilling 100 drilling rig mud pump price, making it idle for some time to enter the mud after a certain number of openings, formal drilling. (3) Start drilling footage speed control, to be drilled to the lower casing 1m, then at normal speed drilling. (4) drilling operations carried out continuously without interruption. For some reason stop drilling 100 drilling rig picture, then capping the orifice shield, and the proposed drill tunnels to prevent underground drilling, while maintaining a mud hole surface height and mud weight, viscosity to meet the requirements. 100 drilling rig manufacturers _ _ Prius Linxia 100 drilling rig provided by Luoyang Prius Drilling Equipment Co., Ltd.
