1. Introduction & Core Purpose

This guide is specifically tailored for the Lanzhou LS 3NB1000C mud pump, focusing on the 107.14.01.00 series parts—including frame assemblies, lubrication systems, power transmission components, sealing elements, and fasteners. It addresses the distinct needs of two key user groups: procurement teams requiring model-accurate, standard-compliant parts to eliminate mismatch risks, and on-site maintenance/technical personnel seeking practical guidance for fault troubleshooting, component protection, and equipment longevity. The core purpose is to serve as a comprehensive dual-reference document, supporting compliant procurement processes while resolving real-world technical challenges, ensuring the Lanzhou LS 3NB1000C maintains reliable, high-efficiency operation in heavy-duty industrial scenarios.

2. Product Overview

The 107.14.01.00 series parts are original-matching core components designed exclusively for the Lanzhou LS 3NB1000C mud pump, covering critical functional categories: structural supports (frame, frame assemble 107.14.600.00-1, frame assy 107.14.90.00), power transmission (drive shaft assy 107.14.10.00, crank shaft assy 107.14.20.00, intermediate rod 107.11.01.02), lubrication systems (forced lubrication system, spray lubrication system 107.14.30.00, spray pump system 107.14.101.00), sealing elements (gaskets, single lip oil seal 107.11.97.00, packing box 107.11.96.03), fasteners (bolts, nuts, washers), and auxiliary parts (dipstick oil lever 107.14.95.00, oil box 107.14.60.00, water retainer 107.11.70.00). All parts adhere to national and industrial standards (GB, JB), ensuring dimensional precision, material compatibility, and durability that align with the LS 3NB1000C’s heavy-duty operational demands.

3. Functional Description

3.1 Structural Support

Frame (107.14.91.00), frame assemble (107.14.600.00-1), and frame assy (107.14.90.00) serve as the pump’s foundational structure, providing stable load-bearing and precise installation positioning for internal transmission and lubrication components. These parts resist deformation under high vibration and extreme pressure, maintaining alignment of crank shafts, drive shafts, and crossheads to prevent component interference and power loss.

3.2 Power Transmission

The drive shaft assy (107.14.10.00), crank shaft assy (107.14.20.00), and intermediate rod (107.11.01.02) form the core power transmission chain, converting rotational energy into reciprocating motion for the pump’s working mechanism. Crosshead guide upper (107.14.90.16) and lower (107.14.90.06) ensure smooth, precise movement of crossheads, reducing frictional wear and extending the service life of transmission components.

3.3 Lubrication & Sealing

Forced lubrication systems, spray lubrication systems (107.14.30.00), and spray pump systems (107.14.101.00) deliver targeted lubrication to rotating and sliding parts (bearings, gears, crossheads), minimizing friction and preventing premature wear. Oil box (107.14.60.00), oil tubing (107.04.90.08), and dipstick oil lever (107.14.95.00) manage lubricant storage, delivery, and level monitoring. Gaskets, single lip oil seals (107.11.97.00), and packing boxes (107.11.96.03) prevent lubricant leakage and external contamination (dust, moisture, drilling fluid), protecting internal components from corrosion and damage.

3.4 Fastening & Auxiliary Functions

Fasteners—including bolts (GB5783-86, 107.11.99.00), nuts (GB6170-86), and washers (GB93-87, GB97.1-85)—secure all components, ensuring assembly stability under high vibration. Pins (GB119-86), wires, and water retainers (107.11.70.00) provide auxiliary fixing and protection, preventing part detachment and water ingress that could compromise the lubrication system. Covers, windows covers (107.14.102.00, 107.04.90.0a), and plugs (JB1000-77) shield internal parts from external debris and environmental damage.

4. Structural Features

The 107.14.01.00 series parts adopt a modular design, facilitating easy disassembly, assembly, and replacement to minimize maintenance downtime. Structural components (frame, frame assy) are crafted from high-strength carbon steel or alloy steel, treated with quenching and tempering to enhance rigidity and fatigue resistance in compliance with GB/T 3077-2015. Lubrication system parts feature precision-machined internal passages for uniform lubricant distribution, while sealing components use oil-resistant, asbestos-free rubber or high-quality metal materials to adapt to varying pressure and temperature conditions. Fasteners undergo surface galvanization or anti-rust coating, improving corrosion resistance in harsh industrial environments.

5. Application Conditions

These parts are engineered specifically for the Lanzhou LS 3NB1000C mud pump, widely used in oil & gas drilling, mining exploration, and industrial sludge transportation. They perform reliably in extreme working conditions, including ambient temperatures ranging from -25°C to 65°C, operating pressures up to 40MPa, and high-vibration (≤ 4.0mm/s) and dusty environments. The parts maintain stability in humid, corrosive settings (exposed to drilling fluid, mine water) and meet the continuous operation requirements of heavy-duty mud pumps in industrial applications.

6. Maintenance Recommendations

6.1 Routine Inspection

Conduct daily checks of lubricant levels using the dipstick oil lever (107.14.95.00) and inspect for leakage from gaskets, oil seals, and oil tubings. Inspect fasteners weekly for tightness, retightening per standard torque specifications (GB/T 3098.1-2010) if loose. Monthly, examine frame components and crosshead guides for deformation or wear, and verify crosshead movement for smoothness.

6.2 Regular Replacement

Replace lubricants every 800 working hours, cleaning the oil box and lubrication passages to avoid contamination. Replace gaskets after each disassembly or every 600 working hours; replace single lip oil seals (107.11.97.00) and packing boxes (107.11.96.03) every 1200 working hours or immediately if leakage occurs. Replace fasteners every 2000 working hours or if thread damage, corrosion, or fatigue is detected.

6.3 Storage & Handling

Store parts in a dry, well-ventilated warehouse, avoiding direct sunlight and humid conditions. Seal gaskets and oil seals in airtight packaging to prevent aging. Use specialized lifting equipment for heavy components (frame assy, crank shaft assy) to avoid impact damage. Clean all parts thoroughly to remove debris and rust before installation, ensuring precise fit and optimal performance.

7. On-Site Fault Repair Cases

Case 1: Lubricant Leakage from Oil Box Gasket Failure

Fault Phenomenon: The Lanzhou LS 3NB1000C pump exhibited continuous lubricant leakage from the oil box (107.14.60.00), with frequent lubricant replenishment required. Diagnosis: Disassembly revealed aging and cracking of gasket 107.14.01.00, which had exceeded its service life and lost sealing capability. Repair: Replaced the gasket with an original-matched part, cleaned the oil box sealing surface, and tightened bolts (GB5783-86 M20x55) to 65-70N·m. Result: Leakage ceased, lubricant levels stabilized, and the pump operated normally.

Case 2: Crosshead Jamming Due to Guide Wear

Fault Phenomenon: The pump experienced abnormal noise, increased vibration, and reduced output, with the drive shaft assy (107.14.10.00) failing to rotate smoothly. Diagnosis: Inspection found severe wear on the crosshead guide lower (107.14.90.06), with wear depth exceeding 0.9mm, causing crosshead jamming. Repair: Replaced the crosshead guide, adjusted crosshead clearance to 0.15-0.20mm, and applied lubricant to the guide surface. Result: Jamming was resolved, vibration and noise returned to normal, and power transmission was restored.

Case 3: Fastener Loosening Causing Frame Assy Vibration

Fault Phenomenon: The frame assy (107.14.90.00) displayed excessive vibration during operation, with bolts (GB5783-86 M16x30) loosening repeatedly. Diagnosis: Washers (GB93-37 16) showed elastic fatigue, failing to provide reliable locking, and bolts were under-tightened. Repair: Replaced bolts and washers, applied thread lock adhesive, and tightened evenly to 60-65N·m. Result: Frame vibration was eliminated, fasteners remained secure, and pump operation stabilized.

Case 4: Lubrication System Contamination from Oil Seal Damage

Fault Phenomenon: Lubricant turned turbid with metal particles, leading to increased wear on the crank shaft assy (107.14.20.00). Diagnosis: The single lip oil seal (107.11.97.00) was damaged, allowing external dust and debris to enter the lubrication system. Repair: Replaced the oil seal, drained contaminated lubricant, cleaned the entire lubrication system, and refilled with ISO VG 68 extreme pressure lubricant. Result: Lubricant clarity was restored, crank shaft wear stopped, and component service life was extended.
