The main function of the excavator water pump is to pressurize the coolant and circulate it within the cooling system.
The excavator water pump plays a crucial role in the cooling system through its specific structure and function. Specifically, the functions of the excavator water pump include the following:
1. Pressurizing and Circulating Coolant: The water pump is driven by gears and operates at a speed 1.5 times that of the diesel engine. As the pump impeller rotates, the coolant is carried along with the impeller and is pushed to the edge of the pump casing by centrifugal force. It then reaches the outlet pipe or radiator through the tangential outlet of the impeller, ensuring that the coolant circulates throughout the entire cooling system.
2. Collaboration with the Thermostat: The thermostat automatically controls the flow and circulation path of the coolant based on the engine’s operating temperature. When the temperature is low, the main valve and auxiliary valve of the thermostat partially open to adjust the temperature of the engine coolant, switching between large and small circulation to ensure that the engine operates stably within an appropriate temperature range.
3. Faults and Maintenance: Common faults that may occur with the excavator water pump include water leakage, insufficient pump flow, inadequate pump pressure, and unusual noises or vibrations from the pump. These issues may be related to the wear of sealing components, blockages, or unreasonable structural design, and timely repairs are necessary to ensure the normal operation of the pump.
In summary, the excavator water pump not only maintains the normal operating temperature of the engine by pressurizing and circulating coolant but also ensures that the engine remains within the optimal working temperature range under various working conditions through its collaboration with the thermostat. Regular inspection and maintenance of the water pump are also essential for ensuring the normal operation of the excavator.
