Workover Drilling Rig Mud Tank System for Africa

Recently one set of workover drilling rig mud tank system are ready for delivery to Africa. The technical configuration is as below:
1. 2 units of GNZS594J-SHBJ 4 panel shale shaker with possum belly flow divider, 4 pcs of composite material frame shaker screen are installed on the shale shaker, as the primary separation equipment of the workover drilling rig mud tank system.


2. 1 unit of GNZCQ-270B vacuum degasser, self contained, no need extra jet pump. The vacuum degasser is suitable for various mud recycling system to separate gas from mud, the purpose is to remain the specific gravity and mud viscosity, also to protect the centrifugal pump from damaged from gas cut mud. Under the atmospheric pressure, the mud enters the rotor hollow shaft through the suction pipe and ejected towards the tank wall through the windows around the hollow shaft. Due to collision and the action of the separation wheel, a thin layer of drilling fluid is formed, causing the bubbles immersed in the mud to break and the gas to escape. Through the suction of the vacuum pump and the separation of the gas water separator, the gas is discharged to a safe area through the exhaust pipe, and the mud is discharged from the mud outlet by the centrifugal force generated by the impeller driven by main motor.


3. 4 units of GNJBQ055G mud agitators installed on the mud tank for agitating of drilling mud
4. 1 unit of GNSB3X2C-9J centrifugal pump
5. 1 unit of GNSLH-110C jet mud mixer with mud mixing hopper and 11KW mixing pump installed on the skid
6. 1 unit of GNZYQ1000A mud gas separator
