Technical Description of Solid Control Centrifuge

Solids control centrifuge is a four-phase solids control equipment for processing drilling fluid in drilling operations. It is also called horizontal screw decanter centrifuge or horizontal sedimentation decanter centrifuge. According to different rotary speeds, it is divided into low-speed centrifuge, high-speed centrifuge and Variable Frequency Drive (VFD) decanter centrifuge. It is used to recover barite, remove 2-7μm fine solid particles, control the density and viscosity of drilling fluids, also it's important processing equipment for drilling fluid mud recycling system.

Working principle of centrifuge

The drum and the spiral rotate in the same direction at a certain speed difference. The material is continuously introduced into the inner cylinder of the feeding spiral from the feed pipe, and then enters the drum after acceleration. Under the action of the centrifugal force, the heavier solid phase is deposited on the drum wall to form a sediment layer. The feeding spiral continuously pushes the deposited solid phase to the cone end of the drum and is discharged outside the machine through the slag discharge port. The lighter liquid phase forms an inner liquid ring, which continuously overflows the drum from the overflow port at the large end of the drum and is discharged outside the machine through the liquid discharge port.

Technical Features:

1. Excellent separation efficiency: Utilizing advanced centrifugal technology to achieve highly efficient solid-liquid separation. It can separate suspensions containing solid particles larger than 0.005mm and concentrations ranging from 2% to 40%. The solids and liquid phases after separation can achieve high purity.

2. High degree of automation: equipped with a programmable controller, it can realize automatic feeding, separation, washing and unloading operations, and can be seamlessly connected with the automated production line to improve production efficiency

3. Strong adaptability: It has great adaptability to materials and can separate solid particles sizes in wide range. It can also perform normal separation when the solid phase particle sizes are uneven. It can be widely used in different industries and materials separation of different properties.

4. Stable and reliable operation: high-quality materials and advanced manufacturing technology are used to ensure the stability and reliability of the equipment under high-speed rotation. At the same time, it is equipped with mechanical and electrical dual overload protection devices, which is safe to use.

Daily Maintenance

1.Cleaning: After using, clean the centrifuge's exterior to prevent oil, dust, and debris from entering the interior. Wipe the exterior with a damp cloth, avoiding the use of organic solvents to prevent damage to the coating. Regularly clean the interior of the centrifuge chamber to remove any residual material to prevent corrosion of the rotor or chamber.

2. Lubrication: Check the lubrication of the motor and transmission parts regularly, generally every 3 to 6 months, and add or replace lubricating oil as needed to ensure good lubrication between the components and reduce wear and friction.

Check components: Regularly check the various components of the centrifuge, such as the drum, spiral, bearings, seals, belts, etc., to check for abnormal conditions such as wear, looseness, leakage, etc.

3. Check electrical equipment: Regularly check motors, circuits, control systems and other electrical equipment to ensure normal operation, check for damaged wires, loose plugs and other issues

In summary, centrifuges are very important for maintaining the efficiency of oil drilling operations by effectively separating materials and keeping drilling fluids reliable property.
