Discover the Power of the Kobelco SK200-10 Excavator’s Gear Pump
The Kobelco SK200-10 is a high-performance excavator, and one of the core components of its hydraulic system is the gear pump. A gear pump (Gear Pump) is a key component in a hydraulic system used to transfer power and pressure, and it pushes fluid from a low-pressure area to a high-pressure area through the engagement of two meshing gears. In the SK200-10 excavator, the specific configuration of the gear pump includes two variable displacement pumps and one gear pump, ensuring stable and efficient hydraulic power is provided under various working conditions.
Gear Pump Description: A gear pump is a positive displacement pump that moves fluid through the engagement of two gears. One gear is driven by the drive shaft, and the other gear rotates with it. The pump’s suction chamber is formed between the gear teeth and is enclosed by the pump housing and end plates. As the gear teeth disengage at the inlet, a partial vacuum is created, allowing fluid to flow in and fill the space, which is then carried to the periphery of the gear. As the gear teeth reengage at the outlet, the fluid is forced out.
Gear Pump Details: The gear pump in the SK200-10 excavator consists of three main parts: a pump housing with inlet and outlet ports and two gears. The design of this pump is simple and robust, with only two moving parts, which makes them highly reliable in high-pressure applications. The maximum displacement flow rate of the gear pump is 1 x 20 L/min, working in conjunction with two variable displacement pumps (maximum displacement flow rate of 2 x 220 L/min) to provide efficient hydraulic power [6†source][8†source].
Gear Pump Example: The configuration of the gear pump in the Kobelco SK200-10 excavator exemplifies its adaptability to complex working environments. The engine model is HINO J05ETG-KSSG, with an engine power of 114 kW / 2,000 min-1, and a bucket capacity of 0.93 m³, these specifications highlight the high efficiency and versatility of the SK200-10 excavator [6†source].
Conclusion: The gear pump in the Kobelco SK200-10 excavator is an integral part of its hydraulic system, improving the operational efficiency and performance of the excavator through precise fluid control. Understanding the working principle and characteristics of the gear pump can help operators better maintain and optimize the excavator’s performance. By supplementing these technical details and application background, we can gain a deeper understanding of the importance of the gear pump in the Kobelco SK200-10 excavator and its role in the field of heavy machinery.
