Problems solved by technology

The wet cylinder liner is in direct contact with the coolant, and is inevitably gradually corroded by cavitation; while the dry cylinder liner is not in direct contact with the coolant, but the cylinder liner seat is also subject to cavitation, and the cylinder liner seat is gradually corroded into through holes or After the crack, it will further damage the dry cylinder liner

Embodiment Construction

[0019] With reference to accompanying drawing 1,2 and 3, engine coolant anti-vibration cavitation performance evaluation device of the present invention comprises a tested solution heating device 1 (being an electric heating plate), and tested solution is placed on tested solution heating device 1 and carries out heating. A cavitation test device and a temperature control device 2 are placed above the test solution heating device 1 . The temperature control device 2 is integrated with the test solution heating device 1 through a fixed bracket. The temperature control device is equipped with a temperature sensor 3 , the temperature sensor 3 senses the temperature of the test solution, and transmits the temperature signal to the temperature control device 2 . The temperature control device 2 converts the temperature signal into a digital signal for processing. When the test solution was heated to 80 degrees by the test solution heating device 1, the temperature control device ...

Description

technical field [0001] The invention relates to a chemical experiment device, in particular to a device capable of evaluating the anti-vibration cavitation performance of engine coolant. Background technique [0002] Cavitation means that the surface of the engine wet cylinder liner in contact with the coolant is destroyed into some needle-shaped holes, which gradually expand and deepen, and finally form deep holes or cracks; the holes are generally clean without corrosion products. The wet cylinder liner is in direct contact with the coolant, and is inevitably gradually corroded by cavitation; while the dry cylinder liner is not in direct contact with the coolant, but the cylinder liner seat is also subject to cavitation, and the cylinder liner seat is gradually corroded into through holes or After the crack, it will further damage the dry cylinder liner. It is generally believed that cavitation is caused by high-frequency vibration of the cylinder liner. Mechanical vibra...
