Drilling Rig Solids control equipments spare parts manufacturer in China

As a professional drilling rig solids control equipments manufacturer in China, we provide complete spare parts for our OEM equipments, and also replacement shaker screens for other brand shale shaker. Recently one batch of drilling rig solids control equipments spare parts are ready for maintenance of our solids control equipments. The list of spare parts including:
For Vertical cuttings dryer:


Different opening screen basket with scraper, Bell jar assembly with scraper, Rotor assembly with flights, Gearbox, pulley of power unit, air knife components, belt
The maintenance of the centralized lubrication system of GN vertical cuttings dryer is very easy, the user need to clean the oil tank regularly. If found abnormal, remove the screws at the four corners of the oil tank to separate the oil tank from others, tighten the 4 screws of the upper cover and oil tank. The mud discharged through the screen basket gap contains solid particles, which will damage the screen basket. When the solids layer increased to specific gap, the screen basket need to be replaced, otherwise the drilling cuttings dryness can not meet the technical requirement. Regularly check the wear of screen basket scraper, and adjust the gap between the scraper and the screen basket to keep the gap in a normal range.
For decanter centrifuge：


Hydraulic coupler assembly, Bearing block
For screw conveyor:
Variator, auger drive, hanger shaft


For screw pump:
Stator, rotor, universal joint, gearbox , variable speed gearbox
For VFD control panel, electrical parts and components, such as drives, PLC, pressure gauge, HMI Display unit, etc.
Except for these spare parts, we also produce replacement shaker screens for different brands shale shaker from API 20 to API 325 which comply with API RP 13C standard. If you need solids control spare parts and shaker screens, pls contact GN solids control.

Vacuum Degasser and Mud Agitator for China Oilfield Service Company

Several sets of vacuum degasser and mud agitators are ready for delivery to China oil oilfield service company.


GN solids control can provide different types mud agitator for different application, including coupler connection mud agitator, direct connection mud agitator, vertical mud agitator, etc. The gearbox to be used with mud agitator is heavy duty helical bevel type gearbox for reliable operation, especially suitable for heavy mud. We will install different explosion proof standard motor for different project’s requirement, control panel can be optional as client’s requirement, such as IEC EX, ATEX, CNEX, etc. The impeller size and shaft length can be customized as your mud tank dimension.
When the agitator impeller come into contact with the drilling fluids, it forces it to generate vortex motion, thereby preventing the sedimentation of solid particles in the drilling mud, achieving the effect of uniform mixing of solid and liquid phases and consistent density. The connecting plate sandwiched in the middle of the impeller can prevent the solid particles of mud from depositing in the lower part of the impeller after shutdown, thereby reducing the resistance of solid materials to the impeller when starting again, and avoiding the accident of burning the motor due to starting overload. When motor is running, it drives the input shaft of the gearbox to rotate through the rotation of the motor. The output shaft of the gearbox drives the mixing shaft to rotate through a rigid coupling, and the mixing shaft is connected to the impeller through bolts for transmission.
To select proper quantity and model mud agitator for the solids control system mud tank, we will clear the drilling fluids density, mud tank dimension, equipments list, etc. information, then we will select proper model for our client.
