Core Purpose & Equipment Compatibility
This catalog features premium sealing components exclusively engineered for the ZP275 Rotary Table, a critical drilling equipment component. Tailored to drilling contractors, oilfield maintenance engineers, and offshore drilling operation teams, the kit addresses the core demand of preventing oil leakage and contaminant ingress—common failures that cause costly downtime in high-torque, dusty, and high-pressure drilling environments. Its primary purpose is to restore the rotary table’s sealing integrity, ensure smooth power transmission, and extend equipment service life, directly supporting continuous and safe drilling workflows.
1. O-Ring Components
O-rings are vital for maintaining oil tightness in ZP275 rotary table joints and mating surfaces. In harsh drilling conditions, they face thermal cycling, high-pressure oil exposure, and abrasive dust, leading to rubber aging, compression set, and surface abrasion—resulting in oil leakage and internal component corrosion. These precision O-rings are manufactured with high-performance rubber materials, offering excellent oil resistance, elastic recovery, and fatigue resistance, ensuring reliable sealing performance in extreme drilling scenarios.
1.1 O-Ring Components Details
No. | Product Name | Specification | Material | Primary Wear Causes | Damage Prevention Notes |
1 | O-ring | 425×8.6 | Nitrile Butadiene Rubber (NBR) 70 Shore A; enhanced tensile strength and oil resistance | 1. Long-term exposure to high-temperature drilling fluid and gear oil causes rubber aging and hardening; 2. Improper installation leads to uneven compression and localized stress concentration. | 1. Use a non-metallic installation tool to avoid stretching or scratching the O-ring; maintain a compression ratio of 25-35%. 2. Ensure the sealing groove is clean and free of burrs before installation to prevent surface damage. |
2 | O-ring | 800×8.6 | FKM (Viton) 75 Shore A; high-temperature resistance (up to 200°C) and chemical stability | 1. Thermal shock from sudden temperature changes in drilling operations causes rubber cracking; 2. Abrasive dust particles embedded in the sealing surface abrade the O-ring. | 1. Store O-rings in a cool, dark, and ozone-free environment to prevent premature aging. 2. Install a secondary dust seal around the mating surface to block abrasive particles from reaching the O-ring. |
3 | O-ring | 1000×8.6 | FKM (Viton) with reinforcing fiber; superior pressure resistance and dimensional stability | 1. High-pressure oil in the rotary table causes extrusion deformation of the O-ring; 2. Improper storage leading to permanent creasing and material fatigue. | 1. Ensure the O-ring is not stacked or folded during storage; use a flat storage rack. 2. Verify that the operating oil pressure does not exceed the O-ring’s rated pressure (≥10 MPa) to avoid extrusion damage. |
2. Oil Seal Components
Oil seals are critical for preventing oil leakage from the ZP275 rotary table’s rotating shafts and housings. In drilling operations, they endure high-speed shaft rotation, dust ingress, and shaft surface wear, leading to lip damage, spring failure, and oil seepage—resulting in lubrication loss and shaft corrosion. These high-precision oil seals feature optimized lip designs and durable materials, ensuring excellent wear resistance and sealing performance, even under continuous high-speed rotation conditions.
2.1 Oil Seal Components Details
No. | Product Name | Specification | Material | Primary Wear Causes | Damage Prevention Notes |
1 | Oil seal | 180×220×15 | Polytetrafluoroethylene (PTFE) lip with NBR body and stainless steel spring; low friction and high wear resistance | 1. Shaft surface scratches or corrosion damage the PTFE lip; 2. Lack of lubrication on the lip during start-up causes dry friction and rapid wear. | 1. Inspect the shaft surface for scratches; polish or replace shafts with surface roughness exceeding Ra 0.8μm. 2. Apply a thin layer of compatible grease to the seal lip before installation to ensure initial lubrication. |
