Charge pumps are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
It supplies low-pressure oil to the closed-loop system, maintains charge pressure, and compensates for internal leakage.
It is typically a gear-type hydraulic charge pump known for stable performance and simple structure.
They are commonly used in excavators, loaders, agricultural machinery, and hydrostatic transmission systems.
The differences mainly relate to system compatibility, configuration, and specific application requirements.
Charge pressure prevents cavitation, ensures lubrication, and maintains efficient system operation.
Low pressure, abnormal noise, overheating, and reduced machine performance are typical indicators.
Yes, as long as the replacement matches the original specifications such as mounting size, pressure rating, and displacement.
Use clean hydraulic oil, replace filters regularly, inspect seals and gears, and maintain proper oil levels and temperature.
Charge pumps are manufactured in compliance with international standards, ensuring high performance and reliability:
ISO 9001: Certified for quality management systems.
CE Certification: Ensures compliance with European safety, health, and environmental protection standards.
RoHS Compliance: Ensures the pump does not contain hazardous materials.
Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
