The working principle of the automobile mechanical pump is to send the coolant pump to the cooling water channel of the engine through the rotation of the impeller, taking away the heat generated by the engine to ensure that the engine works at a suitable temperature. When the impeller rotates, the coolant is driven by the impeller to rotate together, and is thrown to the edge of the impeller under the action of centrifugal force, and then sent to the engine water jacket through the outlet pipe pressure. At the same time, the pressure at the center of the impeller is reduced, and the coolant in the radiator is sucked into the center of the impeller through the inlet pipe, forming a continuous cycle
Maintenance precautions :
troubleshooting : if the packing of the pump shaft is worn out, it should be added in time. It will leak gas and affect the energy consumption of the motor and the life of the impeller
bottom valve leakage treatment : When the bottom valve leaks, do not fill the water inlet pipe with dry soil. It should be repaired or replaced with a new
maintenance after use : after using the pump to put the water clean, it is best to remove the water pipe to rinse with clean water. The tape should also be removed and cleaned to dry. It should not be stained with oil or coated with sticky things
Check the impeller and bearing : carefully check whether there are cracks on the impeller and whether the impeller is loose when fixed on the bearing. If there are cracks and loose phenomenon to timely maintenance
