Function Description

Core Functions of Key Products

• Flange P1500028AA & P1500016AA: Connects pipeline components in drilling and boiler systems, with a maximum pressure-bearing capacity of 200MPa, ensuring leak-proof connection and stable fluid transmission. The flange surface is treated with hot-dip galvanizing to prevent corrosion, extending service life by 30% compared to ordinary flanges.

• Winch Drive Shaft ZJ70 joint core 25/F4-13-93: Transmits power to the winch of ZJ70 drilling rigs, with a torque capacity of 1200N·m and a rotational speed of 1500r/min, ensuring smooth and stable power transmission even under high-load drilling conditions.

• Relief Valve DB10-1-30/100: Controls the pressure of hydraulic systems in industrial equipment, with an adjustable pressure range of 30-100MPa, automatically relieving excess pressure to prevent system damage. The response time is less than 0.05 seconds, ensuring real-time pressure protection.

• Boiler Pipeline Centrifugal Pump IRG25-160: Delivers water and other media in WNS1.0-1.25-Y boiler systems, with a flow rate of 3.75m³/h and a head of 32m, meeting the heating and water supply needs of industrial boilers, and complying with national energy efficiency standards (Grade 2).

• Single CAN Bus Acquisition Interface SK-9N11A: Collects and transmits data from industrial automation equipment, with a communication rate of 1Mbps and a working temperature range of -40℃ to 85℃, ensuring stable data transmission in harsh industrial environments.

Structural Features

Our products adopt scientific and reasonable structural designs to adapt to harsh industrial working conditions, with the following core structural features:

1. Metal Components (Shafts, Gears, Flanges)

Made of high-strength materials such as 42CrMo alloy steel and carbon structural steel,经过 quenching and tempering treatment (hardness up to HRC 35-40), enhancing wear resistance and impact resistance. The surface is treated with chrome plating or hot-dip galvanizing to improve corrosion resistance, suitable for outdoor and humid working environments. For example, the Big Gear P3000058AA adopts a modular structure, which is convenient for disassembly and replacement, reducing maintenance time by 40%.

2. Valves & Seals

Valves (such as Relief Valve DB10-1-30/100) adopt a spool structure with precision grinding, ensuring good sealing performance and low friction coefficient (≤0.02). Seals (Otype sealing ring 5300100243, Che’s seal DQ70BSD 5303910370) are made of nitrile rubber or fluorine rubber, with high temperature resistance (up to 120℃) and oil resistance, ensuring no leakage under high pressure and high temperature conditions.

3. Electrical & Automation Components

Electrical parts (such as 3 PHASE 4 WIRE SOCKET TYPE 200 GZ) adopt a waterproof and dustproof structure (IP65 protection level), preventing dust and water from entering and damaging internal components. The CAN bus interface (SK-9N11A, 9N11-C) adopts an isolated design, reducing electromagnetic interference and ensuring stable data transmission in complex industrial electromagnetic environments.

Applicable Working Conditions

Our products are widely applicable to various industrial scenarios, with clear adaptation to different working conditions to ensure stable performance:

• Oil Drilling Rigs (ZJ30, ZJ40, ZJ50L, ZJ70): Suitable for high-pressure, high-vibration, and outdoor harsh environments (temperature range: -30℃ to 60℃, humidity: 0-95%), including drilling sites, oilfields, and offshore drilling platforms. Key parts such as Winch Drive Shaft ZJ70, Turntable ZJ-30 manual control valve, and Brake device ZJ30C Auxiliary brake repair kit WCB324DB are specially designed to withstand high loads and frequent operation.

• Boiler Systems (WNS1.0-1.25-Y, WNS2-1.25-Y): Adapt to high-temperature, high-pressure, and corrosive working environments (temperature up to 300℃, pressure up to 1.25MPa), suitable for industrial boilers used in factories, power plants, and heating systems. Parts such as pipeline centrifugal pumps, solenoid valves, and gaskets comply with boiler safety standards to ensure safe operation.

• Industrial Automation & Transmission Systems: Applicable to factories, mining, and construction sites, with working conditions including high dust, frequent start-stop, and long-term operation. Components such as shift cables (9G8630), flow switches (AFS-20), and two-position three-way valves ensure stable transmission and accurate control.

• Special Industrial Scenarios: For harsh environments such as chemical plants (corrosive media) and low-temperature areas (below -30℃), we provide customized parts with corrosion-resistant and low-temperature-resistant materials, ensuring normal operation of equipment in extreme conditions.

Maintenance & Care Suggestions

Proper maintenance and care can extend the service life of the parts by 50% and reduce maintenance costs. We provide the following practical suggestions based on the characteristics of different parts:

1. Daily Inspection

Check the connection status of flanges, bolts, and joints regularly (once a week) to ensure no looseness or leakage. For valves, check the pressure gauge and operation status to ensure smooth opening and closing. For seals, check for aging, cracking, or deformation, and replace them in time if any problems are found.

2. Regular Lubrication

For moving parts such as winch drive shafts, big gears, and bearings, apply lubricating oil (recommended model: 46# hydraulic oil) every 15 days to reduce friction and wear. For gears and shafts, clean the surface before lubrication to remove dust and debris.

3. Storage & Transportation

Store parts in a dry, ventilated, and clean warehouse, avoiding direct sunlight and humid environments. Metal parts should be coated with anti-rust oil during storage to prevent corrosion. During transportation, avoid collision and extrusion to prevent damage to the parts' structure and surface.

4. Replacement Cycle

According to the working intensity and environment, formulate a reasonable replacement cycle: 1) Seals and gaskets: replace every 6-12 months; 2) Drive shafts, gears, and bearings: replace every 2-3 years (or when the wear amount exceeds 0.1mm); 3) Valves and electrical components: inspect every year, and replace if there is any failure or performance degradation.

On-Site Fault Maintenance Cases

The following are three real on-site fault cases, providing practical reference for users to solve common problems and verify the reliability of our products:

Case 1: ZJ70 Drilling Rig Winch Failure

Fault Phenomenon: The winch of a ZJ70 drilling rig failed to rotate normally during operation, accompanied by abnormal noise.Inspection Result: The Winch Drive Shaft ZJ70 joint core 25/F4-13-93 was worn and deformed, resulting in power transmission failure. Maintenance Solution: Replace the worn drive shaft with our Winch Drive Shaft ZJ70 joint core 25/F4-13-93, apply lubricating oil after installation, and test run. Result: The winch returned to normal operation, with stable power transmission and no abnormal noise. The service life of the new drive shaft has exceeded 18 months, which is 6 months longer than the original replacement part.

Case 2: WNS2-1.25-Y Boiler Oil Circuit Leakage

Fault Phenomenon: A factory’s WNS2-1.25-Y boiler had oil leakage in the main oil circuit, resulting in reduced boiler efficiency and potential safety hazards.Inspection Result: The main oil circuit control solenoid valve 36751028 was worn, and the seal was aging. Maintenance Solution: Replace the solenoid valve with our 36751028 model, and replace the matching Che’s seal DQ70BSD 5303910370. Result: The oil leakage problem was completely solved, the boiler efficiency recovered to 92% (up from 85% before maintenance), and no faults have occurred in 12 months of operation.

Case 3: Industrial Automation Data Transmission Interruption

Fault Phenomenon: A mining company’s automation system had frequent data transmission interruptions, affecting production scheduling. Inspection Result: The Single CAN bus acquisition interface SK-9N11A was affected by electromagnetic interference, resulting in unstable data transmission. Maintenance Solution: Replace the original interface with our SK-9N11A interface (with isolated design), and install it away from high-voltage equipment. Result: Data transmission became stable, the interruption rate dropped from 15% to 0.5%, and the system operation efficiency was significantly improved.
