Cooling water pump of automobile engine

By test, the fuel consumption reduce the centrifugal clutch slip zone, in the model test, by the vehicle speed and engine speed determined ratio, and found some ratio is less than the minimum ratio, assumed that this is due to the slipping clutch caused. When the clutch is combined for a long time, it will seriously affect the fuel consumption and service life. In order to enable the two to take into account, the use of the computer, including clutch and other all movement of the simulation.
Automotive engine cooling water pump is to prevent heated engine overheating of components, an important component for ensuring the normal work of the engine and test its performance is the product, but also essential for automotive products quality assurance. Due to the special working condition of the automobile, the cooling water pump also has complex working condition and the national standard GB1882-89 requirements to test its performance to 40%-120%n range (n for pump rated speed), spaced evenly take four or four more speed, each kind of speed measurement test 6 (or above) the flow of data in and test every need and measured its head, flow and shaft power and calculate the instantaneous efficiency. The traditional test bench adopts manual adjustment and reading. However, due to the different pump in the head, flow load is different, resulting in the speed of the pump also produce fluctuations, and the pump test system with a large hysteresis. Therefore, by manual adjustment, reading test methods, both time-consuming and more than adults for the error. Development of computer testing system is to eliminate human error and improve the test accuracy and automation level of the automobile engine cooling water pump, and reduce the labor intensity of testing to ensure the quality of products.
