This week, a batch of solids control equipment was dispatched from GN Solids Control. The equipment will be used in Chinese rig site for a drilling rig mud circulation system.

It is a set of full package solids control mud processing equipment including below equipment:
1) 2 sets of linear motion shale shaker: GNZS703F. It is a 3-panel shale shaker for drilling mud pre-separation.
2) 1 set of desander mud cleaner, model GNZS752F-2S. The desander mud cleaner is equipped with a big under flow shale shaker the same model with first stage solids control shale shaker. It is easy for clients to stock spare parts and replacement screens for both shale shaker and mud cleaner.
3) 1 set of Desilter mud cleaner, model GNZS752F-12N. The desilter mud cleaner is equipped with the same under flow shale shaker with first stage solids control shale shaker and desander mud cleaner.
4) 2 sets of Decanter centrifuge, model GNLW452. It is a economic standard middle speed decanter centrifuge for barite recovery.
5) 2 sets of mud tanks.
6) 1 package of jet mud mixing system.

Besides the mentioned equipment, GN Solids Control is also capable to make drilling mud agitator, mud gun, centrifugal pump which are fully interchangeable with international popular brand, other VFD centrifuges, FHD decanter centrifuge, Vertical cuttings dryer, high G dryer, screw conveyor, and various model replacement shaker screens for different brand shaker models.

GN VFD decanter centrifuge is with advantages for self-protection and smart control.
The LPC program of GN hydraulic centrifuge is with below self-protection functions:
The start/stop of the hydraulic centrifuge and the start /stop of the centrifuge feed pump are logical connected for protection.
1. After start the centrifuge, only after the centrifuge bowl achieve the preset speed and running for some seconds, the feeding pump can be started for feeding mud.
2. When the decanter centrifuge is stopped, feeding pump cannot be started.
3. During the centrifuge running, the centrifuge will not be cut off if directly press the centrifuge stop button. Only by pressing the stop button of the feeding pump and stop the feeding pump, and then the centrifuge can be powered off.
