Abstract
Description
Technical Field
[0001] This utility model relates to a testing device, and more particularly to an offline testing device for a crystallizer used in aluminum alloy casting, belonging to the field of equipment testing technology. Background Technology
[0002] In aluminum alloy casting, the crystallizer is a critical piece of equipment, and the performance of its cooling water system directly affects the quality of the castings and production efficiency. The main function of the crystallizer is to rapidly cool the liquid aluminum alloy through the circulation of cooling water, forming a strong outer shell within the crystallizer to ensure the shape and dimensional accuracy of the castings. Therefore, the stability and reliability of the crystallizer's cooling water system are fundamental to the stability of casting process parameters. However, in actual production, the following problems may occur with the crystallizer's cooling water system:
[0003] ① Cooling water leakage: Poor sealing of the cooling water channel of the crystallizer, or wear and corrosion after long-term use, may lead to cooling water leakage; this will not only waste water resources, but may also cause safety accidents, or even lead to casting quality defects.
[0004] ② Cooling water channel blockage: During the circulation process, the cooling water may carry impurities or cause scale buildup due to water quality issues, thus blocking the cooling water channels. This will affect the flow rate and velocity of the cooling water, resulting in uneven cooling, which in turn will affect the cooling effect and quality of the casting. Utility Model Content

[0014] 2. This utility model can perform comprehensive testing on the cooling water system of the crystallizer, including pressure testing, flow testing, and leakage inspection. By setting flow valves and water pumps, the size and pressure of the water flow can be precisely controlled, ensuring the accuracy and reliability of the test results and reducing downtime caused by equipment failure.
[0015] 3. This utility model uses water pipes to distribute water from the water tank to various branch water pipes via a water pump, which can verify whether the cooling water channels inside the crystallizer are unobstructed and whether the water flow distribution is uniform; it can prevent production interruptions caused by cooling water leakage, blockage or uneven cooling when the crystallizer is put into use, improve the continuous operation time and efficiency of the production line, and ensure the smooth progress of construction.
