What is the function of the excavator water pump?

The excavator water pump is generally installed in the front of the engine. The water pump is under the tank (radiator). Excavator water pumps generally use hydraulic pumps.

What is the function of the excavator water pump?

① Function and structure The function of the water pump is to pressurize the cooling water, so that the cooling water circulates in the cooling system. Centrifugal water pumps are widely used in automobile engines, which are composed of water pump casings, water pump shafts, impellers, and inlet and outlet pipes. The transmission mode of the water pump is gear transmission, and the speed of the water pump is 1.5 times the speed of the diesel engine. water pump installation and maintenance parts.

②Working principle When the impeller of the water pump rotates, the coolant in the water pump is driven by the impeller to rotate together, and is thrown to the edge of the water pump casing under the action of centrifugal force, and then is pressed to the water outlet pipe on the casing that is tangential to the impeller. Inside the engine water jacket. At the same time, the pressure at the center of the impeller is reduced; the coolant in the radiator is sucked into the pump cavity through the water inlet pipe, so that the coolant in the entire cooling system circulates.

What is the definition of excavator water pump?

Excavator water pump is a hydraulic component that provides pressurized liquid for hydraulic transmission, and is a type of pump. Its function is to convert the mechanical energy of power machines (such as electric motors and internal combustion engines) into liquid pressure energy. There are many factors affecting the service life of the hydraulic pump, in addition to the design and manufacturing factors of the pump itself, the selection of some components related to the use of the pump (such as couplings, oil filters, etc.), and the operation during the commissioning process are also related.

The working principle of the excavator water pump is that the movement brings about a change in the volume of the pump cavity, thereby compressing the fluid so that the fluid has pressure energy. , the necessary condition is that the pump cavity has a change in the sealing volume

Does the excavator water pump burn affect the engine?

A broken water pump will affect the cooling system of the engine itself, resulting in high water temperature. The engine dissipates heat through the cooling system. The negative impact of the failure of the cooling system is that the entire engine runs at high temperature, which will affect its normal function.

90% of the high temperature of the excavator is the problem of the water tank, but it is necessary to check the belt tension, fan blades, thermostat, water pump, and air duct circulation, as well as the engine cylinder head gasket, which may cause high temperature.

Seeing this, do you also want to order a water pump? If necessary, you can contact Guangzhou HERUI, they will provide the water pump of the best quality.
