Product Overview

Core Purpose

These spare parts are essential for the normal operation, maintenance, and repair of oilfield drilling equipment. The 2.1.01.001 Hydraulic Pump provides stable power for the hydraulic system, ensuring smooth operation of lifting, rotating, and drilling mechanisms; the 1.01.24.004 Bearing Backing Plate TPEC Top Drive protects the top drive’s bearing system from wear and impact, extending the service life of the core component; cartridge valves (including 2.2.08.005, 2.2.08.017) control the flow and pressure of hydraulic oil, preventing system leaks and pressure loss; fasteners such as 4.10.02.001 Hexagon Head Bolts with Holes and 4.10.09.006 Spring Washers ensure the tight connection of equipment components, avoiding loosening caused by high vibration during drilling. Every part is designed to address specific operational pain points, ensuring the drilling equipment runs continuously and stably in harsh oilfield environments.

Function Description

Each spare part has a clear and irreplaceable function in the equipment system. The 2.1.01.001 Hydraulic Pump converts mechanical energy into hydraulic energy, with a maximum output pressure of 31.5MPa, which solves the problem of insufficient power in the hydraulic system during heavy-load drilling. The 1.01.24.004 Bearing Backing Plate is made of high-strength alloy steel, with a thickness of 18mm, which effectively disperses the pressure on the bearing, avoiding bearing damage caused by uneven force. Cartridge valves adopt a plug-in design, which is easy to disassemble and maintain, solving the problem of difficult maintenance and long downtime of traditional valves. Electrical connectors (such as 3.03.02.03.057, 3.03.02.04.012) ensure stable transmission of electrical signals, preventing signal interruption caused by dust, moisture, and vibration in the oilfield. All parts work together to ensure the safe and efficient operation of the entire drilling system.

Structural Features

Our spare parts are designed with the harsh oilfield environment in mind, with outstanding structural advantages. The 2.1.01.001 Hydraulic Pump adopts a dual-cylinder structure, with a compact design that saves installation space and improves heat dissipation efficiency, solving the problem of pump overheating during long-term operation. The 1.01.24.004 Bearing Backing Plate is processed by precision grinding, with a surface roughness of Ra0.8μm, ensuring close fit with the bearing and reducing friction. Fasteners are made of high-strength carbon steel, with galvanized surface treatment, which can resist corrosion from saltwater and chemical substances in the oilfield, with a service life of up to 5,200 working hours. Connector bodies (such as 2.4.37.004, 2.4.34.016) adopt a sealed structure, with an IP67 protection level, preventing dust and water from entering the internal components, ensuring stable operation in dusty and rainy environments.

Applicable Working Conditions

These spare parts are widely applicable to various oilfield working conditions, including onshore oilfields (such as the Permian Basin in the United States, Daqing Oilfield in China), offshore oil platforms, and desert oilfields. They can withstand extreme temperatures ranging from -40℃ to 85℃, adapt to high humidity (up to 95%), high vibration (frequency 10-50Hz), and high corrosion environments. Whether it’s deep well drilling (depth up to 6,000 meters), horizontal drilling, or workover operations, our spare parts can maintain stable performance, solving the problem of poor adaptability of ordinary spare parts to harsh oilfield conditions. They are also compatible with mainstream drilling equipment brands and models, reducing the trouble of finding matching parts.

Maintenance and Care Recommendations

To extend the service life of the spare parts and ensure equipment stability, our engineers provide practical maintenance advice. For the 2.1.01.001 Hydraulic Pump, check the oil level and oil quality every 500 working hours, replace the hydraulic oil every 2,000 working hours, and clean the filter element regularly to avoid oil pollution causing pump wear. For the 1.01.24.004 Bearing Backing Plate, apply lubricating grease every 300 working hours, check for cracks and deformation regularly, and replace it immediately if any damage is found. Fasteners should be checked and tightened every 100 working hours, especially after high-vibration operations, to avoid loosening. Cartridge valves should be disassembled and cleaned every 1,500 working hours, and the sealing ring should be replaced if there is leakage. Avoid using incompatible lubricants or cleaning agents, as this will damage the parts. Our team also provides on-site maintenance guidance to help customers solve maintenance problems in a timely manner.
