3. Functional Description

3.1 Structural Support

Frame (107.11.91.00-1), frame assemble (107.11.600.00-1), 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—key challenges in mud pump operation—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 (107.11.10.00), crank shaft assy (107.11.20.00), and intermediate rod (107.11.01.02) form the core power transmission chain, converting rotational energy from the motor into reciprocating motion for the pump’s mud 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, which are critical for consistent pump performance.

3.3 Lubrication & Sealing

Forced lubrication system (107.11.40.00), spray lubrication system (107.11.30.00), and spray pump system (107.11.101.00) deliver targeted lubrication to rotating and sliding parts (bearings, gears, crossheads), minimizing friction and preventing premature wear—essential for reducing maintenance frequency. Oil box (107.11.60.00), oil tubing (107.11.90.08), and dipstick oil lever (107.11.95.00) manage lubricant storage, delivery, and level monitoring, ensuring the system always has sufficient lubrication. Gaskets, single lip oil seals (107.11.97.00), and packing boxes (107.11.96.03) prevent lubricant leakage and external contamination (dust, moisture, mud), 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 (107.11.93.00-1), windows covers (107.04.90.07, 107.04.90.03), and plugs (JB1000-77 M60x2) shield internal parts from external debris and environmental damage, maintaining component integrity. Rubber washers (D3-4-67) enhance sealing performance for plugs and covers, further preventing leakage.

4. Structural Features

The 107.11.01.00 series parts adopt a modular design, facilitating easy disassembly, assembly, and replacement to minimize maintenance downtime and labor costs—critical for maximizing pump availability in continuous operation scenarios. 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, ensuring no critical components are under-lubricated. 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.
