Withstands high-pressure liquid pressure and is the core component of the pressurization system. Ceramic Plunger: Responsible for liquid pressurization, featuring wear and corrosion resistance.
Crankshaft & Connecting Rod: Converts rotational power into reciprocating piston motion, ensuring stable operation.
Valve Assembly: Controls unidirectional liquid flow, improving suction and drainage efficiency.
Water Seal & Oil Seal: Isolates water passages and the lubrication system, improving sealing reliability.
Bearing: Supports the transmission system, reduces friction, and improves operational smoothness.
Manufacturing Capability
Precision Machining: Employs CNC machining centers, CNC grinding, and honing processes to ensure dimensional accuracy and assembly consistency of key components.
Standardized Assembly: Key components undergo standard torque assembly and pressure and seal testing to ensure stable product performance.
Stable Supply Capability: Mature production lines support mass production, and stable delivery times can be arranged according to project requirements, meeting long-term supply needs.
Quality Control
Raw Material Inspection: Inspect the dimensions, material properties, and appearance of major metal materials.
Parts Machining Inspection: Inspect key dimensions, tolerances, and coaxiality to ensure component consistency.
Assembly Process Control: Complete assembly according to standard processes and confirm torque at key components.
Pressure Performance Testing: Perform pressure and operational tests on each product before shipment to verify its performance.
Sealing Inspection: Test the pump body's sealing performance to reduce leakage risk.
Final Finished Product Inspection: Shipped only after completing appearance, performance, and packaging inspections.
