All parts adhere to national and industrial standards (GB, JB), ensuring dimensional precision, material compatibility, and durability that align with the LS Slush Pump’s heavy-duty operational demands in harsh working environments.

3. Functional Description

3.1 Structural Support

Frame (107.11.91.00-3), frame assemble (107.12.600.00-1), and frame assy (107.11.90.00) 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, power loss, and potential equipment damage.

3.2 Power Transmission

The drive shaft assy (107.12.10.00), crank shaft assy (107.12.20.00), and intermediate rod (107.11.01.02) form the core power transmission chain, converting rotational energy into reciprocating motion for the pump’s slurry conveying mechanism. Crosshead guide upper (107.11.90.05) and lower (107.11.90.03) ensure smooth, precise movement of crossheads, reducing frictional wear and extending the service life of key transmission components.

3.3 Lubrication & Sealing

Forced lubrication systems, spray lubrication systems (107.12.30.00), and spray pump systems (107.11.101.00) deliver targeted lubrication to rotating and sliding parts (bearings, gears, crossheads), minimizing friction and preventing premature wear. Oil box (107.11.60.00), oil tubing (107.04.90.08), and dipstick oil lever (107.12.95.00) 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, slurry), 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 (107.12.93.00-1), windows covers (107.04.90.07, 107.04.90.03), and plugs (JB1000-77) shield internal parts from external debris and environmental damage, maintaining component integrity.

4. Structural Features

The 107.12.01.00 series parts adopt a modular design, facilitating easy disassembly, assembly, and replacement to minimize maintenance downtime and labor costs. 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 humid, dusty industrial environments.

5. Application Conditions

These parts are engineered specifically for the Lanzhou LS Slush Pump, widely used in oil & gas drilling, mining exploration, slurry transportation, and industrial wastewater treatment. 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 slurry, mine water, and chemical media) and meet the continuous operation requirements of heavy-duty slush pumps in industrial applications.

6. Maintenance Recommendations

6.1 Routine Inspection

Conduct daily checks of lubricant levels using the dipstick oil lever (107.12.95.00) 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, verify crosshead movement for smoothness, and clean filters in the lubrication system to prevent clogging.

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, and replace worn crosshead guides to prevent jamming.

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 and deterioration. 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 Slush Pump exhibited continuous lubricant leakage from the oil box (107.11.60.00), requiring frequent lubricant replenishment and affecting pump operation. Diagnosis: Disassembly revealed aging and cracking of gasket 107.11.90.33, 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 (GB5783-87 M20x55) to 65-70N·m. Result: Leakage ceased, lubricant levels stabilized, and the pump operated normally without further issues.

Case 2: Crosshead Jamming Due to Guide Wear

Fault Phenomenon: The pump experienced abnormal noise, increased vibration, and reduced slurry conveying efficiency, with the drive shaft assy (107.12.10.00) failing to rotate smoothly. Diagnosis: Inspection found severe wear on the crosshead guide lower (107.11.90.03), with wear depth exceeding 0.9mm, causing crosshead jamming. Repair: Replaced the crosshead guide, adjusted crosshead clearance to 0.15-0.20mm, and applied ISO VG 68 lubricant to the guide surface. Result: Jamming was resolved, vibration and noise returned to normal, and the pump’s conveying efficiency was fully restored.

Case 3: Fastener Loosening Causing Frame Assy Vibration

Fault Phenomenon: The frame assy (107.11.90.00) displayed excessive vibration during operation, with bolts (GB5373-86 M16x30) loosening repeatedly and posing safety risks.Diagnosis: Washers (GB93-87 16) showed elastic fatigue, failing to provide reliable locking, and bolts were under-tightened during previous maintenance.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, reducing safety hazards.

Case 4: Lubrication System Contamination from Oil Seal Damage

Fault Phenomenon: Lubricant turned turbid with metal particles and slurry residues, leading to increased wear on the crank shaft assy (107.12.20.00) and potential component failure. Diagnosis: The single lip oil seal (107.11.97.00) was damaged, allowing external dust and slurry to enter the lubrication system. Repair: Replaced the oil seal, drained contaminated lubricant, cleaned the entire lubrication system and oil box, and refilled with ISO VG 68 extreme pressure lubricant. Result: Lubricant clarity was restored, crank shaft wear stopped, and component service life was extended, reducing maintenance costs.
