Horizontal directional drilling short name is HDD. HDD technology has the obvious in oil and gas pipelines being past the rivers, lakes, highway, railway hub and other obstacles and important area. HDD site all is in the rivers, lakes, the traffic trunk line. Neither dig in the excavation of a large area nor make mud discharge randomly; So it is very important to equip with mud recovery system.
Mud systems have a lot of moving parts that must be kept in order to keep them in premium working order. If you do not grease and adjust centrifugal packing on a regular basis, it will leak causing not only a mess but also hazardous work environment. Bearings require lubrication for long life. Cones can get plug with debris making them inactive thus reducing your cleaning capacity. Screens get torn allowing trash to go into the system causing plugging problems.
The mud recycling system set up to handle the mud stream and sets out the problems encountered in getting this system running and the alterations planned to enhance the system. The paper also looks at the diffuser losses for 2002 season compared with the combined mud and bagasse losses of previous seasons.
With three types of impellers Aipu mud agitators are available and are sized according to tank volume and expected duty. Active mud system compartments (such as solids removal sections, mud mixing sections and slug pits) need a higher shear blade to produce more immediate mixing. Bulk storage compartments need a low-shear blade that maintains suspension in a gentler manner.
