Core Purpose & Target User Needs

These spare parts are specifically designed to solve common operational pain points in oilfield drilling, solids control, and fluid treatment systems, serving target users including onshore/offshore drilling contractors, oilfield service companies, and E&P operators. The core purpose is to minimize unplanned downtime, reduce maintenance costs, and ensure stable operation of drilling equipment. Our products address key user needs: replacing worn cyclones, screen cloths, and pump components that cause inefficient solids separation; fixing leakage issues from damaged mechanical seals; resolving vibration instability from faulty shock absorbers and springs; and replacing worn parts to extend the overall service life of drilling equipment. Each component is tailored to fit specific equipment models—such as SWACO desilter cyclone 96-22-312, Derek 2000 vibrating screen, and SB6*8 sand pump—ensuring perfect compatibility and avoiding the hassle of custom modifications.

Product Introduction & Key Features

1. Cyclones & Cyclone Components

Our cyclone series includes ZQJ300 small cone, ZQJ250*2/1.5*0.6 desander cyclone, ZCNQ-125-8 125mm cyclone, ZQJ100*10/1.5*0.6 100mm desilter cyclone, and SWACO desilter cyclone cone 96-22-312, along with matching components like ZQJ250*2-1.5*0.6 cyclone nozzle, desander cone assembly 2000 6606-51, and ZQJ100*10/1.5*0.6 desilter cyclone clip.

Function: Efficiently separate solid particles (sand, shale, etc.) from drilling fluid, ensuring the fluid meets drilling requirements and protecting downstream equipment from wear. The cyclone nozzle and cone work together to control flow velocity and separation precision, solving the problem of inefficient solids separation caused by worn or misaligned cyclone parts.

Structural Features: Made of high-chromium alloy steel with a hardness of 62 HRC, the cyclone cone and nozzle resist erosion from abrasive solids; the precision-machined flange design ensures leak-free connection, while the quick-release clip (ZQJ100*10/1.5*0.6) allows for easy maintenance and replacement. The ZQJ250*2/1.5*0.6 desander cyclone features an optimized conical structure that reduces fluid turbulence and improves separation efficiency.

2. Screen Cloths & Screening Components

We supply a full range of screen cloths, including Derek 2000 1220*1142mm 80 mesh, PWP 1050*700 220/210/150/100 mesh hook plate screen, GX-1/700*1050 60/100 mesh plane screen, 2YZS 120/20 mesh 2.2*0.6m stainless steel mesh, and desander/desilter double-layer screen cloths (1600*600mm*200 mesh, 200/20 mesh*2100*600mm).

Function: Filter solid particles in drilling fluid, preventing screen blinding and ensuring smooth fluid flow. The double-layer design (coarse mesh outer layer, fine mesh inner layer) solves the problem of rapid wear and blinding in high-solids drilling environments, while the wavy anti-hook edge (Derek 1050*695 40 mesh) minimizes edge wear and extends service life to 720 operating hours, far exceeding the industry average of 400 hours.

Structural Features: Made of 316L stainless steel (resistant to corrosion from oil-based and water-based drilling fluid), with precision weaving that ensures aperture error ≤±0.02mm. The hook plate and hook edge design ensures secure installation on vibrating screens, while the soft screen variant (1250*800 150/20 mesh) adapts to high-vibration environments without tearing. All screen cloths comply with Q/ZYYQ 007-2024 drilling fluid vibrating screen standards, with a screen surface vertical acceleration of 5-8g and整机 noise ≤85dB(A).

3. Sand Pump & Mechanical Seal Components

Key components include SB6*8 FJ-13 sand pump mechanical seal, SB6*8 FJ-13 left/right pump head, and related accessories. These parts are designed for sand pumps in solids control systems, solving the pain points of seal leakage and pump head wear caused by abrasive drilling fluid.

Function: The SB6*8 FJ-13 mechanical seal prevents drilling fluid leakage from the pump shaft, while the pump head (left/right) ensures stable fluid flow and pressure. The mechanical seal uses tungsten carbide seats and nitrile rubber elastomers, withstanding temperatures up to 120°C and pressures up to 1.6 MPa, suitable for harsh sour service environments.

Structural Features: The pump head is made of hardened alloy steel with a wear-resistant coating, extending service life to 2800 operating hours; the mechanical seal features a single-face design with self-lubricating properties, reducing friction and avoiding premature failure. Both components are direct replacements for SB6*8 series sand pumps, requiring no modifications to the pump body.

4. Vibrating Screen Accessories

This category includes VLB-35224-W 2.2KW 1410r/min vibrating screen motor, 2E48-90F-3TA shock absorbing rubber and motor, SWACO vibrating screen spring LW3S00079, GXZS-II hydraulic adjustment device, and GXZS-111 vibrating screen hook screw.

Function: Ensure stable vibration of the screen, reduce equipment fatigue, and adjust screen inclination for optimal screening efficiency. The VLB-35224-W motor provides stable power (2.2KW, 1410r/min) with IP66 protection and F-class insulation, suitable for dusty, wet oilfield environments[superscript:7].

Structural Features: The shock absorbing rubber (2E48-90F-3TA) dampens vibration, reducing stress on the screen frame; the hydraulic adjustment device (GXZS-II) allows fine-tuning of screen angle (0-5°) for different drilling fluid conditions; the vibrating screen spring (LW3S00079) is made of high-tensile steel, with a service life of 12000 operating hours.

Applicable Working Conditions

All products are designed to perform reliably in the following oilfield conditions, aligning with API and industry standards:

- Drilling fluid: Solids concentration up to 18% by volume, pH 6-12, compatible with both oil-based and water-based fluids.

- Temperature range: -20°C to 120°C, suitable for both cold onshore fields (e.g., Canada) and high-temperature offshore environments.

- Pressure range: Up to 105 MPa (15,000 psi) for cyclones and pump components, meeting API 16A requirements for well control systems.

- Vibration conditions: Vibrating screen vibration frequency 10-30 Hz, G-force up to 8g, with components designed to withstand continuous high-amplitude vibration.

- Sour service: NACE MR0175/ISO 15156 qualified, suitable for environments with H₂S partial pressure ≥0.0003 MPa and chloride concentration up to 50 ppm.

Maintenance & Care Guidelines

To maximize component lifespan and reduce maintenance costs, our engineers recommend the following practical tips (avoiding common pitfalls):

1. Screen Cloths: Inspect daily for blinding or tears; clean with high-pressure water (≤20 MPa) to remove solids. Replace when aperture size deviates by more than 0.1mm from the original. Store in a dry, cool area to prevent rust—avoid stacking heavy objects on screen cloths (a common mistake that causes permanent deformation).

2. Cyclones & Nozzles: Check weekly for erosion; replace if wall thickness is reduced by 0.3mm. Clean nozzles every 3 days to prevent clogging, which reduces separation efficiency. Ensure cyclone alignment—misalignment (even 2°) can cut separation efficiency by half.

3. Mechanical Seals & Pump Heads: Lubricate seals with API 6A Grade 2 grease every 500 operating hours. Replace seals if leakage exceeds 5 drops per minute. Inspect pump head impeller clearance weekly—if it exceeds 0.5mm, replace the pump head to avoid reduced flow rate.

4. Vibrating Screen Accessories: Check shock absorbing rubber monthly for cracks; replace if hardness exceeds 75 Shore A. Tighten hook screws (GXZS-111) every 100 operating hours to prevent screen detachment.
