Function & Structural Features

Core Functions

Our industrial parts are designed to perform three core functions: ensuring equipment reliability, improving operational efficiency, and reducing maintenance costs. Each part is engineered to meet the specific functional requirements of its application: hydraulic parts deliver stable fluid power, electrical parts ensure accurate monitoring and control, transmission parts enable efficient power transfer, and seals prevent leakage and equipment damage. For example, the FESTO Break out air cylinder VL/O-3-1/2 9983 W202 provides a maximum force of 5000N, enabling quick and efficient breakout of drill pipes, reducing drilling downtime by 15%.

Structural Features

All our parts feature a robust and durable structure, designed to withstand harsh industrial environments (high pressure, high temperature, dust, and corrosion). Key structural features include:

• High-strength materials: Most mechanical parts are made of alloy steel (e.g., 40Cr, 35CrMo) or high-quality aluminum alloy, with heat treatment to enhance hardness and wear resistance. For example, the Main bearing 3G3003760 HY GH3161-02.22 G is made of bearing steel GCr15, with a hardness of HRC 60-64 and a service life of up to 10,000 operating hours.

• Precision machining: All parts are machined using CNC equipment with a tolerance of ±0.01mm, ensuring 100% compatibility with OE standards. The Jaw aXis Z9.HL127R, for example, is machined with a concentricity of ≤0.02mm, ensuring smooth operation and reducing vibration.

• Corrosion-resistant coatings: Critical parts (e.g., pressure valve covers, fittings) are coated with zinc plating or epoxy resin, providing corrosion resistance in high-humidity and corrosive environments (such as oilfields and chemical plants).

• Modular design: Many parts (e.g., electrical actuators, reducers) feature a modular design, making installation, maintenance, and replacement quick and easy, reducing maintenance time by 20%.

Applicable Working Conditions

Our industrial parts are designed to perform reliably in a wide range of harsh industrial working conditions, including:

1. Oil and Gas Drilling Sites

Parts such as the Reverse Reducer ZJ30CZ-04-01-00 RG Petro, High pressure drilling hose ZG 100-35, and Air and water tap SD-00E ZJ30 RG rig are specifically designed for ZJ30 and other drilling rigs. They can withstand high pressure (up to 35MPa), high temperature (ranging from -20℃ to 150℃), and dusty environments, ensuring stable operation during drilling, completion, and workover operations.

2. Heavy Machinery Manufacturing

Hydraulic parts (PVS-2B-35N3-12 hydraulic pump), transmission parts (XWD 8-71 screw motor reducer), and seals (GH3161-03.06) are suitable for heavy machinery such as excavators, loaders, and cranes. They can withstand heavy loads, frequent start-stop cycles, and vibration, ensuring long service life and reliable performance.

3. Industrial Workshops & Factories

Electrical parts (PA866K-803AI/M current meter, BLF-73No11D electrical actuator), ventilation parts (ZN310LSA4 blower working wheel), and air conditioning parts (YORK 1843639 control board) are designed for industrial workshops, providing accurate monitoring, efficient ventilation, and stable temperature control in environments with high dust, high humidity, and continuous operation.

4. Chemical & Petrochemical Plants

Corrosion-resistant parts such as the Gasket AH0000060102, O-ring 120X5.7 JB/ZQ4224-97, and Pressure valve cover 4M50104.13JT25-02-47C are suitable for chemical and petrochemical plants, where they are exposed to corrosive media (acids, alkalis, oils) and high pressure, ensuring leak-proof and reliable operation.

Maintenance & Care Recommendations

Proper maintenance of industrial parts is critical to extending their service life and ensuring equipment reliability. Below are practical maintenance recommendations tailored to our product range:

1. Routine Inspection

Conduct weekly inspections of hydraulic parts (pumps, valves, hoses) for leaks, cracks, or abnormal noise. Check electrical parts (current meters, control boards) for loose connections or damage to the casing. For seals and gaskets, inspect for wear, deformation, or hardening—replace them every 6 months or if any damage is found.

2. Lubrication

Lubricate transmission parts (reducers, bearings, jaw axes) every 3 months using high-quality lubricating oil (e.g., ISO VG 46 hydraulic oil for hydraulic pumps, lithium-based grease for bearings). Ensure the lubricant level is within the recommended range to prevent friction and wear. The Main bearing 3G3003760 HY GH3161-02.22 G, for example, requires lubrication every 250 operating hours to maintain optimal performance.

3. Cleaning

Keep parts clean to prevent dust, debris, and oil contamination. Clean the ZN310LSA4 blower working wheel monthly to remove dust buildup, which can reduce air volume by up to 30% if left unaddressed. For hydraulic fittings and valves, clean the thread and sealing surfaces before installation to prevent leaks.

4. Storage

Store unused parts in a dry, clean, and well-ventilated environment, away from direct sunlight and corrosive media. Seals and O-rings should be stored in a cool place (temperature ≤25℃) to prevent aging. Mechanical parts (reducers, bearings) should be coated with anti-rust oil before storage to prevent corrosion.

5. Replacement Guidelines

Replace parts when they reach their service life (e.g., 1R-0762 fuel filter should be replaced every 500 operating hours or 6 months, whichever comes first). Replace any part that shows signs of excessive wear, damage, or failure to avoid equipment breakdown. Always use genuine replacement parts to ensure compatibility and performance—generic parts can reduce equipment service life by 50% and increase the risk of downtime.

On-Site Fault Repair Cases

Below are three real on-site fault repair cases, demonstrating how our parts solve practical operational problems and minimize downtime:

Case 1: Hydraulic Pump Failure in ZJ30 Drilling Rig

Fault Description: A ZJ30 drilling rig in an oilfield experienced a sudden drop in hydraulic pressure, causing the drill pipe to fail to lift. The on-site maintenance team inspected the system and found that the original hydraulic pump (non-genuine replacement) had a worn rotor, leading to reduced flow rate and pressure.

Repair Solution: The team replaced the faulty pump with our NACHI PVS-2B-35N3-12 hydraulic pump, which is 100% compatible with ZJ30 drilling rigs. The new pump features a high-wear rotor and precision-machined components, restoring hydraulic pressure to the recommended 35MPa.

Result: The drilling rig resumed operation within 2 hours, and the new pump has been in stable operation for over 8,000 hours without any faults, reducing maintenance costs by 35% compared to the previous non-genuine pump.

Case 2: Blower Working Wheel Damage in Industrial Workshop

Fault Description: An industrial workshop using a ZN310 blower reported poor ventilation and increased noise. Inspection revealed that the original working wheel had cracks and excessive wear, reducing air volume by 40% and increasing energy consumption.

Repair Solution: We supplied a ZN310LSA4 blower working wheel, made of high-strength aluminum alloy with a precision-machined impeller. The maintenance team replaced the damaged working wheel, ensuring proper alignment and balance.

Result: Ventilation efficiency was restored to 100%, noise levels were reduced from 85dB to 72dB, and energy consumption decreased by 18%. The working wheel has been in operation for 6 months without any issues.

Case 3: Electrical Actuator Malfunction in Fan Aeration System

Fault Description: A chemical plant’s fan aeration system failed to control fan speed properly, leading to unstable air flow and poor indoor air quality. The original electrical actuator (generic brand) had a faulty signal receiver, unable to respond to the 4-20mA control signal.

Repair Solution: The plant replaced the faulty actuator with our BLF-73No11DType BS-60 electrical actuator, which features a high-sensitivity signal receiver and stable 380V operation. The actuator was calibrated to match the system’s control signal, ensuring precise speed control.

Result: The fan aeration system resumed stable operation, with air flow control accuracy improved to ±5%, and the actuator has been running reliably for over 10,000 hours, eliminating unplanned downtime.
