Core Purpose & Equipment Compatibility
This catalog features high-performance repair components exclusively engineered for YG180 Travelling Block & Hook and XSL225 Swivel, critical hoisting and circulation equipment in drilling operations. Tailored to drilling contractors, oilfield maintenance teams, and offshore drilling service providers, the kit addresses the core demand of resolving failures caused by worn parts—rampant in high-load, high-vibration, and corrosive drilling environments. Its primary purpose is to restore equipment structural integrity, sealing performance, and rotational stability, minimize unplanned downtime, and ensure safe, continuous drilling hoisting and mud circulation workflows.
1. Sealing Components
Sealing components are indispensable for preventing oil leakage, mud ingress, and corrosion in YG180 travelling block & hook and XSL225 swivel. In harsh drilling conditions, they endure high pressure, thermal cycling, and abrasive mud contamination, leading to rubber aging, lip wear, and sealing failure—resulting in internal component damage and equipment breakdown. These precision sealing parts adopt high-performance materials, offering excellent oil resistance, wear resistance, and environmental adaptability, ensuring reliable sealing in extreme drilling hoisting and circulation scenarios.
1.1 Sealing Components Details
No. | Product Name | Specification | Material | Primary Wear Causes | Damage Prevention Notes |
1 | O-ring | 70*3.1 | Nitrile Butadiene Rubber (NBR) 70 Shore A; excellent oil resistance and elastic recovery | 1. Long-term exposure to high-temperature lubricating oil causes rubber aging and compression set; 2. Installation scratches on the sealing surface lead to localized leakage. | 1. Use a plastic installation tool to avoid stretching or scratching the O-ring; 2. Ensure the sealing groove is clean and free of burrs, and maintain a compression ratio of 25-30%. |
2 | O-ring | 230*7 | 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 mud particles embedded in the sealing surface abrade the O-ring. | 1. Store O-rings in a cool, dark, ozone-free environment to prevent premature aging; 2. Install a secondary dust shield to block mud and debris from reaching the sealing area. |
3 | O-ring | 200*5.3 | FKM (Viton) with reinforcing fiber; enhanced pressure resistance and dimensional stability | 1. High-pressure oil in the travelling block causes extrusion deformation; 2. Improper storage leading to permanent creasing and material fatigue. | 1. Avoid stacking or folding during storage; use a flat storage rack; 2. Verify that the operating oil pressure does not exceed the O-ring’s rated pressure (≥12 MPa). |
4 | O-ring | 24*2.4 | Silicone rubber 65 Shore A; wide temperature range (-40°C to 180°C) | 1. Cold start-up in low-temperature drilling areas causes rubber brittleness; 2. Contaminants in lubricating oil accelerate material degradation. | 1. Pre-heat the equipment to above 0°C before start-up in cold climates; 2. Regularly replace lubricating oil and filters to keep oil clean. |
5 | Dust-proofing seal | YG225-06-00 | Polyurethane (PU) with steel frame; high wear resistance and dust blocking capability | 1. Continuous friction with the moving shaft causes lip wear; 2. Large solid particles impact and scratch the seal lip. | 1. Regularly clean the seal lip and shaft surface to remove accumulated dust; 2. Replace the seal promptly if the lip wear exceeds 1mm to avoid dust ingress. |
6 | Packing | SL135-06 Φ130*Φ93*Φ19 | Aramid fiber-reinforced PTFE; high-temperature resistance and low friction | 1. High-pressure mud erosion causes fiber breakage and sealing failure; 2. Improper compression leads to uneven wear and mud leakage. | 1. Adjust the compression force according to the equipment manual (typically 0.1-0.2 MPa); 2. Regularly inspect for mud leakage and re-tighten or replace the packing as needed. |
2. Elastic Components
Elastic components (e.g., springs) play a critical role in buffering and resetting mechanisms of YG180 travelling block & hook. In high-load and frequent impact drilling scenarios, they are prone to fatigue failure, deformation, and corrosion—leading to mechanism jamming and loss of buffering function. These high-precision springs adopt alloy steel materials and strict heat treatment processes, ensuring excellent fatigue resistance and elastic stability, effectively absorbing impact loads and ensuring the smooth operation of the equipment’s reset mechanism.
2.1 Elastic Components Details
No. | Product Name | Specification | Material | Primary Wear Causes | Damage Prevention Notes |
1 | Spring | YG225-08 | 60Si2Mn alloy spring steel; heat-treated, hardness HRC 45-50 | 1. Repeated cyclic loads from hoisting operations cause fatigue failure; 2. Corrosion from humid drilling environments and oil contamination. | 1. Regularly clean the spring surface and apply anti-corrosion lubricant; 2. Avoid overloading the spring beyond its design limit; inspect for deformation periodically. |
3. Bearing Components
Bearings are core load-bearing and rotational components in YG180 travelling block & hook, enduring high radial and axial loads during hoisting operations. In harsh drilling conditions, inadequate lubrication, dust/mud contamination, and impact loads easily cause raceway pitting, rolling element wear, and cage damage—leading to noisy operation, reduced rotational precision, and even bearing seizure. These bearings adopt high-strength bearing steel and precision grinding technology, ensuring excellent load-carrying capacity and fatigue resistance to adapt to the high-load, high-vibration working environment.
3.1 Bearing Components Details
No. | Product Name | Specification | Material | Primary Wear Causes | Damage Prevention Notes |
1 | Bearing | 9840 | High-carbon chromium bearing steel (GCr15); carburized and quenched, hardness HRC 62-65 | 1. Inadequate grease filling leads to metal-to-metal contact and overheating; 2. Impact loads from sudden hoisting start-stop damage the rolling elements. | 1. Fill the bearing cavity with 35-45% high-temperature lithium-based grease (NLGI Grade 2); 2. Operate the hoisting system with smooth start-stop to avoid shock loads. |
2 | Bearing | 2097938E (GB229-85) | GCr15SiMn bearing steel; precision ground raceways, low friction coefficient | 1. Mud and dust ingress cause abrasive wear of internal components; 2. Shaft misalignment leads to uneven load distribution and edge loading. | 1. Ensure the bearing’s protective seals are intact; replace damaged seals promptly; 2. Check shaft concentricity during installation; correct misalignment exceeding 0.05mm. |
4. Specialized Components for XSL225 Swivel
Specialized components (e.g., washing pipe) are critical for the mud circulation function of XSL225 swivel. In drilling operations, they endure high-pressure mud erosion, corrosion, and mechanical wear—leading to pipe blockage, leakage, and reduced circulation efficiency. These specialized parts are manufactured with high-strength, corrosion-resistant materials, ensuring excellent pressure resistance and wear resistance, effectively guaranteeing the smooth progress of mud circulation in drilling operations.
