- Reliable Power Transmission: The 4KW YB112M-4 motor and precision coupling drive the centrifugal liner washer stably, delivering sufficient flushing fluid without power loss.
- Leak-Proof Pipeline Sealing: Custom rubber gaskets and sealed joints realize zero fluid leakage, resisting long-term vibration and fluid erosion.
- Smooth Fluid Circulation: Standardized flanges, tees and elbows ensure unobstructed fluid delivery, avoiding pipeline blockage and pressure fluctuation.
- Stable Fixed Installation: Reinforced supports and high-strength fasteners fix the spray pump firmly, reducing vibration displacement and component damage.
Structural Characteristics
These spray pump parts feature optimized structures suitable for oilfield field maintenance and long-term durable operation:
- Modular Integrated Design: The base, motor and centrifugal washer form an integrated module, enabling quick disassembly and replacement, simplifying maintenance operations.
- Detachable Pipeline System: Independent rubber hoses and threaded joints facilitate quick replacement of damaged pipelines, reducing repair time.
- Multi-Specification Sealing Configuration: Gaskets of different thicknesses and sizes meet sealing needs of various interfaces, ensuring tight fit and long service life.
- Protective Cover Structure: The special protective cover isolates internal components from dust and mud, prolonging the service life of motor and transmission parts.
- Standardized Fastener System: Unified national standard bolts, nuts and washers ensure high compatibility, making spare parts preparation more convenient.
Maintenance and Upkeep Suggestions
To ensure stable operation of the electrical liner washer spray pump and prolong service life, follow these field-proven maintenance protocols:
- Daily Inspection: Check the pressure gauge reading for normalcy (0.3-0.8MPa), inspect hose and joint for fluid leakage, monitor motor operating temperature (normal ≤70℃).
- Weekly Maintenance: Clean impurities at the pipeline inlet, retighten all fasteners, check hose aging and clamp tightness.
- Monthly Inspection: Check coupling wear and alignment, inspect gasket sealing performance, clean the centrifugal liner washer interior.
- Regular Replacement: Replace aging rubber hoses and gaskets every 6 months, check motor insulation performance annually, replace severely worn joints.
- Storage Requirements: Store rubber sealing parts in a cool, dark and dry environment, avoid sun exposure and extrusion deformation.

On-site Fault Repair Cases
Case 1: Motor Burnout Caused by Overload Operation
The spray pump failed to output flushing fluid normally, and the motor generated abnormal heat and stopped running. The motor winding burned out due to long-term overload and poor heat dissipation. Maintenance staff replaced the YB112M-4 4KW motor, calibrated the coupling alignment, and the spray pump resumed normal operation after debugging.
Case 2: Fluid Leakage Due to Damaged Rubber Gasket
Obvious flushing fluid leakage occurred at the flange joint of the spray pump, leading to insufficient spray pressure. The rubber gasket was aged and damaged by fluid erosion. Workers replaced the matching gasket, retightened the fastening bolts, and completely eliminated the leakage fault.
Case 3: Pressure Abnormality Triggered by Pipeline Blockage
The spray pump pressure gauge showed abnormal fluctuation, and the liner flushing effect was greatly reduced. Impurities accumulated in the centrifugal liner washer and pipeline, causing blockage. Technicians cleaned the pipeline and washer, replaced slightly worn hoses, and restored normal spray pressure.
