Product Description
K3SP36B Charge Pump functions as an important low-pressure oil supply unit in hydraulic systems. It is installed on the K3SP36B main hydraulic pump and is designed to provide stable charge flow and charge pressure for the main pump. The pump operates based on the principle of volumetric hydraulic transmission. Through the meshing rotation of external gears, the volume of sealed working chambers changes, enabling continuous suction and discharge of hydraulic oil.
The charge pump helps maintain favorable suction conditions for the main pump, supplies oil for hydraulic control circuits, and provides necessary lubrication and cooling for key internal components. When the hydraulic system operates under long-term heavy-load conditions, the charge pump ensures a stable charge pressure supply, helping prevent cavitation and insufficient oil supply. This effectively reduces wear and potential damage to critical components inside the main pump, such as pistons, bearings, and valve plates, ensuring stable and efficient operation of the entire hydraulic system, extending equipment service life, and reducing maintenance costs.

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.
The K3SP36B Charge Pump is a voltage conversion circuit designed to increase or invert voltage using capacitors as energy storage elements instead of inductors. It is commonly used in applications where compact size, low noise, and simple design are required.
The K3SP36B Charge Pump is typically used in:
LCD bias voltage generation
Gate driver circuits
Portable electronic devices
Power management systems
Low-power voltage boosting or inversion applications
Key advantages include:
No need for inductors, which reduces PCB size
Low electromagnetic interference (EMI)
Simple external component requirements
High efficiency for low-power applications
The K3SP36B usually requires a small number of external components, including:
Flying capacitors
Input/output capacitors
Optional resistors for control or feedback
The exact values depend on the operating voltage and load requirements.
Efficiency can be improved by:
Selecting low ESR capacitors
Using recommended capacitor values from the datasheet
Minimizing PCB trace resistance
Operating within the recommended load current range
When designing the PCB:
Place capacitors close to the IC pins
Use short and wide traces for power paths
Ensure proper grounding to reduce noise
Follow the layout recommendations in the datasheet
The K3SP36B Charge Pump is designed to operate within a specified input voltage range defined in the datasheet. Operating within this range ensures stable voltage conversion and optimal performance. Exceeding the recommended input voltage may cause reduced efficiency or potential damage to the device.
The K3SP36B Charge Pump works by periodically switching capacitors between different circuit configurations. During each switching cycle, the capacitors store and transfer charge, allowing the circuit to either boost the input voltage or generate a negative voltage relative to ground without the use of inductors.
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.
