Function Description

Each product is engineered to perform specific critical functions, ensuring the smooth operation of your equipment:

• Drill Bits (2159mm HJT137G, 3112mm MS1952SS): Designed for oilfield drilling, the steel tooth roller bit excels in soft to medium-hard formations, while the PDC drill bit delivers high drilling efficiency and long service life in hard formations, reducing drilling cycle time.

• Hydraulic Valves (3WH6A5X, DBDS10K1/100): Control the flow, pressure, and direction of hydraulic oil in drilling rigs and industrial machinery, ensuring stable operation of hydraulic systems and preventing overpressure damage.

• Expansion Joint 9175K19: Absorbs thermal expansion and contraction of pipelines (such as Y/G10II-2600-SW2 A3 motor pipeline), reduces vibration, and compensates for pipeline misalignment, extending pipeline service life.

• Bearings (GB/T276-1994, EAM005M, AH1301010414): Reduce friction between moving parts (e.g., pinion shaft P2400181AA, roller shaft ZJ-70DB) and support loads, ensuring smooth rotation and reducing wear.

• Sealing Parts (AH1001010404, 15X2.63 O-ring): Prevent leakage of oil, gas, or fluid in hydraulic systems, engines, and pipelines, maintaining system pressure and avoiding environmental pollution and equipment damage.

Structural Features

Our products adopt advanced structural design and high-quality materials to meet the demands of harsh working environments:

• Easy-Align Galvanized Expansion Joint 9175K19: Galvanized surface treatment for corrosion resistance; flexible structure for easy alignment during installation, adapting to pipeline displacement and vibration without deformation.

• PDC Drill Bit 3112mm MS1952SS: Diamond composite cutters with high hardness and wear resistance; optimized bit body structure for improved rock-breaking efficiency and stable drilling trajectory.

• Hydraulic Control Valve 3WH6A5X: Compact structure, precise flow control, and strong pressure resistance; adopt high-quality sealing components to ensure no leakage and long service life.

• Bearings (GB/T276-1994): High-precision rolling elements and raceways, strict dimensional tolerance control, and excellent load-bearing capacity; suitable for high-speed and heavy-load operation.

• Sealing Ring AH1001010404: Made of high-temperature and oil-resistant rubber, precise size matching, and good elasticity, ensuring tight sealing even in high-pressure and high-temperature environments.

Applicable Working Conditions

Our products are widely used in various harsh and complex working environments, mainly including:

• Oilfield Drilling Sites: Suitable for ZJ45, ZJ50, ZJ70D drilling rigs, JC70B drawworks, and PDC/roller bit drilling operations, withstanding high temperature (up to 150℃), high pressure (up to 35MPa), and dusty, corrosive environments.

• Industrial Manufacturing Plants: Applicable to WNS2-1.25-Y boilers, GRL-BX roller heating furnaces, centrifugal fans (YF04 04 11KW low noise), and hydraulic equipment, adapting to continuous operation and high-load working conditions.

• Petrochemical & Pipeline Systems: Used in motor pipelines (Y/G10II-2600-SW2 A3), expansion joints (9175K19), and shuttle valve sleeves (150QMD-00-05), withstanding corrosive media and pipeline vibration.

Maintenance & Care Suggestions

Proper maintenance can extend the service life of mechanical parts and reduce replacement costs. Here are practical suggestions:

• Regular Inspection: Check hydraulic valves (e.g., 3WH6A5X), bearings, and sealing parts every 100 operating hours; replace worn or damaged parts in time (such as O-rings 15X2.63 and friction plates 23041786).

• Cleaning & Lubrication: Keep drill bits, pinion shafts (P2400181AA), and bearings clean; apply appropriate lubricating oil (matching the equipment manual) to reduce friction and prevent rust.

• Storage Requirements: Store parts in a dry, ventilated, and dust-free warehouse; avoid direct sunlight and contact with corrosive substances (especially galvanized expansion joints 9175K19 and gaskets AZ703102010114B1).

• Installation Notes: Ensure parts are correctly installed according to the equipment manual; avoid forced installation (e.g., aligning expansion joints 9175K19 properly to prevent pipeline stress).

• Replace with Matching Parts: When replacing parts, use the same model or compatible products (e.g., replace relief valve 5126000930 with the same part number) to avoid equipment damage due to mismatch.

On-Site Fault Maintenance Cases

Here are 3 real on-site maintenance cases, showing how our parts solve practical problems for customers:

Case 1: Drill Bit Failure in Oilfield Drilling

A customer’s ZJ50 drilling rig used a non-original roller bit, which wore out quickly (only 30 hours of operation) in medium-hard formations, leading to drilling downtime. We recommended our 2159mm HJT137G steel tooth roller bit, which features a reinforced tooth structure and wear-resistant material. After replacement, the drill bit operated stably for 120 hours, reducing downtime by 75% and lowering drilling costs.

Case 2: Hydraulic Valve Leakage in Industrial Hydraulic System

An industrial plant’s hydraulic system (equipped with ZJ45 Martin hydraulic pressure pump PSH-Ⅱ) had serious oil leakage from the handle reversing valve, resulting in reduced system pressure and equipment failure. We supplied the original model 512704300600070000 handle reversing valve, which has a precise sealing structure and high pressure resistance. After installation, the leakage problem was completely solved, and the hydraulic system returned to normal operation.

Case 3: Bearing Damage in Drawworks

A JC70B drawworks’ crosshead bearing (original part) was damaged due to insufficient lubrication and harsh working conditions, causing the drawworks to stop working. We provided AH1301010414 crosshead bearing, which has a high-load design and corrosion-resistant surface. We also guided the customer to optimize lubrication procedures. After replacement, the drawworks operated continuously for 500 hours without failure.
