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.
