TR Solid Control's 450-type decanter centrifuge system has been shipped as a complete set, providing efficient operation.

Recently, the TRLW450×1000N decanter centrifuge independently developed by Xi'an TR Solid Control has completed production testing and been successfully shipped. As the core equipment of the oil drilling fluid solid control system, this equipment will provide an efficient solid-liquid separation solution for oilfield drilling operations with its high separation accuracy and intelligent control characteristics.

TR Solid Control's 450-type horizontal decanter centrifuge (TRLW450×1000N model) boasts core specifications that define high-efficiency separation standards. The TR 450-type horizontal decanter centrifuge achieves a breakthrough in operational efficiency through technological upgrades.

I. Technical parameters of the 450-type centrifuge

1. Core performance: The inner diameter of the drum reaches 450mm and the length is 1000mm. It generates a separation factor of 1210 through high-speed rotation of 2200r/min. The single-machine processing capacity can reach 50m³/h, which can accurately remove harmful fine particles of 2~5μm from drilling fluid.

2. Intelligent control: It adopts a PLC programming control system and an explosion-proof touch screen to monitor key parameters such as drum speed, bearing temperature and whole machine vibration in real time. It can steplessly adjust the speed and differential speed according to the mud characteristics, and is suitable for complex working conditions such as shale gas wells and high temperature and high pressure wells.

3. Energy-saving design: Equipped with a 30kW high-efficiency motor and a lightweight structural design, it significantly reduces energy consumption compared to traditional equipment. With the barite recovery function, it can save tens of thousands of yuan in drilling costs per well.

TR Solids Control's centrifuges have served multiple oilfields in China and overseas projects. For example, in Xinjiang shale gas extraction, by linking with shale shakers and desanders, drilling fluid reuse rates have exceeded 90%, saving approximately 20% of mud costs per well. In trenchless applications such as subway construction, its shear pump and centrifuge combination system can reduce mud solids content from 30% to below 5%, ensuring the safety of tunnel boring machine (TBM) construction.

II. Synergistic Effect of PAM Dosing Device TRJY3000/3-PAM

Functions and Design: This device integrates automatic batching, dissolving, and dosing functions, enabling precise control of the polyacrylamide (PAM) solution concentration (0.1%-0.5%), with a processing capacity of up to 3000 L/h. Its quantitative feeding device and multi-stage stirring system ensure uniform dispersion of the reagent, preventing clumping that could affect the flocculation effect.

In the petroleum industry, PAM is used as a flocculant in drilling fluid treatment to accelerate the sedimentation of solid particles. For example, in wastewater treatment, adding 5-20 ppm of PAM can achieve a suspended solids removal rate of over 95%, while simultaneously reducing solution viscosity and improving centrifuge separation efficiency. The automated dosing of TRJY3000/3-PAM reduces manual intervention and is suitable for 24-hour continuous operation.

Synergistic optimization with centrifuges: The linkage control between the PAM dosing unit and the centrifuge enables an integrated "flocculation-separation" process. By monitoring mud turbidity online, the system automatically adjusts the PAM dosage, reducing the centrifuge processing load by 30%, while simultaneously decreasing the solid phase water content from 85% to below 75%, thus reducing subsequent drill cuttings treatment costs.

III. Safety and Reliability Design of Manifolds and Cables

The standardized configuration of TR Solids' manifold system uses corrosion-resistant stainless steel, conforming to API 16D standards, and can withstand high pressure (≥35MPa) and extreme temperatures (-40℃ to 120℃). For example, in high-pressure mud transportation, its constant diameter design reduces eddies and ensures flow stability, while passing a fire resistance test (704℃, 30 minutes) to meet the needs of emergency conditions such as well blowouts.

The explosion-proof and protective cables feature an armored structure and explosion-proof design, complying with ATEX Zone 1 certification and suitable for flammable and explosive environments in oil and gas fields. Their oil resistance and abrasion resistance ensure long-term stable operation; for example, in the vibration environment of offshore platforms, the cable's insulation performance retention rate exceeds 98%.

The modular design of the system integration and installation manifolds and cables facilitates rapid installation, and on-site fixation using specialized clamps reduces the impact of vibration on connection points. TR's technical team provides one-stop service, including system pressure testing (1.5 times rated pressure) and cable insulation testing, ensuring no leakage risk after equipment commissioning.

Before leaving the factory, TR solid-state control equipment undergoes dynamic balancing tests, no-load trial runs, and load simulation tests to ensure that all indicators meet the standards. During shipment, shockproof packaging and dedicated transport racks are used, with critical components individually protected to prevent damage during transportation.

TR Solids Control's TRLW450×1000NB centrifuge, TRJY3000/3-PAM dosing unit, and matching manifold cables provide an integrated solution for oil drilling fluid treatment through a combination of high-efficiency separation, intelligent control, and safe design. Its technological advantages have been validated in projects both domestically and internationally, particularly in complex conditions such as shale gas extraction and high-temperature, high-pressure wells, where it can significantly improve operational efficiency, reduce costs, and meet environmental protection requirements.

The TR 450 decanter centrifuge can also be widely used in oil-based mud treatment, drill cuttings reduction, and other scenarios. Through solid-liquid separation, it precisely controls the density and viscosity of drilling fluid, reducing subsequent environmental treatment costs. Currently, TR Solids Control's equipment of this type serves integrated solutions for over 3000 drilling platforms.
