HDD Mud Recycling System
HDD, horizontal directional drilling, is a steerable trenchless method of installing underground pipes, conduits and cables in a shallow arc along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area. HDD mud recycling system is a necessary part in the drilling process, using solids control equipments to seperate solids in mud, protecting drilling rig. Dachuan Machinery's HDD mud recycling system is widely used in worldwide.
HDD mud recycling system always contains shale shaker, mud cleaner, centrifugal pumps,
mud agitator, mud tank, jet mud mixer, submersible slurry pump, electric control system, lighting system, ladder, slide walk, handrail valve, pipe line, clean gate, etc.
HDD technology has obvious advantages in crossing rivers, lakes, traffic trunks, railway centers and other obstacles and important districts. The end reaming diameter of HDD is commonly 1.3～1.5 times as long as pipeline diameter.
Mud solid phase control (commonly referred to as solids control) technology in HDD is a principle and technical method of controlling the solid particles existed in mud. Through solids control technology, harmful solids are eliminated and useful solids phase are retained to meet the requirements of HDD technology to mud performance. The harmful solids phase in HDD mud mainly refers to the drilling cuttings which can affect equipments wearing and mud flow performance.
Application of solids phase control system in horizontal directional drilling: the solid control recycling systems used in China manufactured half in domestic and half imported. The imported systems are mainly diminutive, imported with relevant associated drilling rigs; The domestic systems are usually large, manufactured customized. Whether domestic or imported, the selection of solids control system is mainly based on the following rules:
1 The type and size of particles which need to be eliminated or controlled;
2 The quality of mud which need to be maintained.
3 The capacity of drilling rig, clearance rate and cycle rate of solid phase.
