What Is a Kabota K-170l Kh-28 Excavator Drive Pump？

In an automatic transmission, the gear that primarily drives both the hydraulic pump and the lubrication pump is typically the torque converter. The torque converter is connected to the engine’s crankshaft, and it spins at the same speed as the engine. As the engine runs, the torque converter uses fluid dynamics to transmit power to the transmission gears and also drives the transmission’s pumps. Specifically, the impeller within the torque converter is what drives the pumps, supplying the hydraulic pressure required to shift gears and providing lubrication to various transmission components. This centralized system ensures synchronized operation and is crucial for the transmission’s performance.

A normal water pump is designed to move water through a system, ensuring a consistent flow. On the other hand, an oil suction pump is engineered to extract oil from a reservoir or engine, employing a suction mechanism to handle the thicker viscosity of oil.

To achieve 120Nm torque with an EATON 74318 hydraulic motor, a pump is required that can provide around 29.56 MPa pressure, considering the motor’s 40.6 cm³/rev displacement. Consultation with system designers or manufacturers is advisable for precise pump sizing, as system conditions and desired flow rate will impact the selection.

The question is asking about the specific type of hydraulic pump that is used in JCB machinery. JCB, which stands for J.C. Bamford Excavators Ltd., is a British multinational company known for manufacturing heavy equipment like backhoes, excavators, and loaders. These machines commonly employ hydraulic systems to operate various functions such as lifting, digging, and moving. Knowing the type of hydraulic pump used in JCB equipment could be valuable for understanding its performance characteristics, maintenance requirements, and potential for retrofitting or upgrading.
