Function Description

Key Component Functions

• Pump Components (DW40C0608BZ000037 Centrifugal Pump, SB3*4J-9 Horizontal Sand Pump, SP40041A05 Vertical Sewage Pump): These pumps are designed to transport fluids (water, slurry, sewage) in industrial and drilling operations. The centrifugal pump delivers high flow rates for general fluid transfer, the horizontal sand pump handles high-abrasion slurry, and the vertical sewage pump efficiently removes wastewater—all ensuring stable fluid circulation to support production.

• Drilling Rig Components (ZJ30C Drum Shaft, ZJ45 Bridge Bolt, ZJ-40 One-Way Clutch): The drum shaft transmits power to the drawworks for hoisting drill strings; the bridge bolt secures critical rig structures for safe operation; the one-way clutch prevents reverse rotation of components, protecting the transmission system and ensuring safe drilling operations.

• Filter & Sealing Components (1R0726 Filter Element, 666001007 Mechanical Seal, 8T7876 O-Ring): Filter elements remove impurities from oil, hydraulic fluid, and water to protect internal components from wear; mechanical seals and O-rings prevent fluid leakage, ensuring the integrity of hydraulic, lubrication, and fluid systems.

• Valves & Control Components (2A4429 Valve Lock, FP-L6 Anti-Collision Overroll Valve, 4900300037 Pressure Reducing Valve): Valve locks secure valves in fixed positions to prevent accidental operation; anti-collision overroll valves protect equipment from damage due to overtravel; pressure reducing valves regulate system pressure to maintain stable operation and prevent component damage.

• Transmission & Brake Components (ZJ-30C Turbo Torque Converter, ZJ-45 Electromagnetic Eddy Current Brake, Allison CLBT754 Transmission Case): Turbo torque converters transfer power efficiently between the engine and transmission; electromagnetic eddy current brakes provide reliable braking for drilling rigs; Allison transmission cases house and protect transmission components, ensuring smooth power transmission.

Structural Features

Overall Structural Advantages

All our spare parts are manufactured using precision processes and high-quality materials to withstand the harsh conditions of industrial and drilling operations. Key structural features include:

• High-Strength Material Selection: Critical components (drill bits, drum shafts, gear hubs) are made of high-grade alloy steel, wear-resistant cast iron, or carbide materials, providing excellent tensile strength, impact resistance, and corrosion resistance—ideal for high-temperature, high-pressure, and high-dust environments.

• Precision Machining: We use CNC machining technology to ensure dimensional accuracy (tolerance ≤ ±0.01mm), guaranteeing perfect compatibility with original equipment. This eliminates assembly gaps, reduces vibration and noise, and extends component service life.

• Sealing & Protection Design: Sealing components (mechanical seals, O-rings, seal half rings) feature multi-layer sealing structures to prevent fluid leakage and dust entry. Anti-corrosion coatings and heat-treated surfaces further enhance durability in harsh environments.

• Modular & Easy-to-Install Design: Most components (connectors, filter elements, gaskets) adopt a modular structure, making disassembly, assembly, and replacement quick and easy. This reduces maintenance time and labor costs, minimizing equipment downtime.

Applicable Working Conditions

Our spare parts are widely applicable to various industrial and drilling scenarios, including:

• Onshore & Offshore Oil Drilling: Suitable for ZJ30C/ZJ40/ZJ45 series drilling rigs, adapting to diverse geological conditions (sandstone, shale, limestone) and operating stably under high temperature (≤ 90℃) and high pressure (≤ 30MPa).

• Industrial Pump Operations: DW40C0608BZ000037 centrifugal pumps, SB3*4J-9 horizontal sand pumps, and SP40041A05 vertical sewage pumps are ideal for fluid transfer in factories, oil refineries, and wastewater treatment plants—handling clean water, slurry, and sewage efficiently.

• Harsh Environment Operations: Corrosion-resistant filter elements, sealed connectors, and heat-treated components (such as porcelain tube resistors, thermocouples) can withstand humid, dusty, and corrosive environments (desert oilfields, coastal industrial sites).

• Equipment Maintenance & Emergency Repair: All spare parts are interchangeable with original equipment, making them suitable for on-site emergency repairs and daily maintenance of drilling rigs, pumps, transmissions, and hydraulic systems.

Maintenance and Care Suggestions

Daily Maintenance Guidelines

• Regular Inspection: Check the wear status of key components (roller bits, brake shoes, filter elements) every 150 hours of operation. Inspect connectors (gooseneck fittings, end straight connectors) and fasteners (bonnet bolts, bridge bolts) for tightness to prevent loosening or leakage.

• Cleaning & Replacement: Clean filter elements (1R0726, 8193841, 1R-1807) every 250 hours of operation; replace them when the pressure difference exceeds 0.6MPa. Clean pump impellers and pipelines regularly to remove deposits and avoid blockage.

• Lubrication Maintenance: Apply high-quality lubricating oil (meeting API standards) to rotating components (drum shafts, cardan shafts, gear hubs) regularly. Ensure sufficient lubrication to reduce friction and wear, extending component service life.

• Storage Requirements: Store spare parts in a dry, ventilated, dust-free warehouse. Avoid direct sunlight and moisture. Precision components (signal isolation modules, thermocouples) should be stored in shockproof packaging to protect internal electronic parts.

Precautions for Replacement

When replacing spare parts, follow the original equipment operation manual and note the following:

• Confirm the part number and model (e.g., 1114804 bonnet bolt, 666001007 mechanical seal) to ensure compatibility with your equipment. Mismatched parts can cause assembly failure and equipment damage.

• Clean the installation area thoroughly before installing new parts to remove impurities and debris. Check the installation surface for flatness to ensure proper seating.

• For electronic components (signal isolation modules, electronic ballasts), cut off the power supply before replacement to avoid short circuits or component damage.

• After installation, conduct a test run to verify normal operation. Adjust parameters (pressure, flow rate) as needed to ensure the part meets operational requirements.

On-Site Fault Repair Cases

Below are 3 real on-site repair cases, demonstrating how our spare parts solve common equipment issues efficiently:

Case 1: Centrifugal Pump Leakage Due to Mechanical Seal Failure

Site: Industrial factory using DW40C0608BZ000037 centrifugal pump
Fault Phenomenon: Severe fluid leakage from the pump shaft, reduced flow rate, and increased noise.
Inspection Result: The 666001007 mechanical seal was worn and damaged, losing its sealing function.
Repair Solution: Replace the damaged mechanical seal with our 666001007 mechanical seal, clean the pump shaft, and re-align the pump assembly.
Effect After Repair: Leakage was completely eliminated, the pump flow rate returned to normal, and noise was reduced. The pump resumed stable operation, avoiding production downtime.

Case 2: Drilling Rig Brake Failure Caused by Worn Brake Shoes

Site: ZJ45 drilling rig using LT1070*200T ventilated clutch brake shoes
Fault Phenomenon: The rig’s braking performance decreased, and the drill string could not be held stably during hoisting.
Inspection Result: The LT1070*200T brake shoes were severely worn, with the friction material almost completely worn down.
Repair Solution: Replace the worn brake shoes with our LT1070*200T ventilated clutch brake shoes, adjust the brake clearance, and test the braking system.
Effect After Repair: Braking performance was fully restored, the drill string was held stably, and the rig could resume safe drilling operations.

Case 3: Hydraulic System Pressure Instability Due to Clogged Filter Element

Site: ZJ30C drilling rig hydraulic system using 1R0726 filter element
Fault Phenomenon: Hydraulic cylinder movement was slow, system pressure fluctuated, and the hydraulic pump made abnormal noise.
Inspection Result: The 1R0726 filter element was clogged with impurities, restricting oil flow and causing pressure instability.
Repair Solution: Replace the clogged filter element with our 1R0726 filter element, clean the hydraulic oil tank, and replace the hydraulic oil.
Effect After Repair: Hydraulic system pressure stabilized, the hydraulic cylinder moved smoothly, and abnormal noise was eliminated. The drilling rig’s hydraulic system operated normally.
