Not long ago, with the first batch of 50 heavy-duty engines smoothly off the assembly line, it was announced that the current domestic heavy-duty diesel engine test line with world advanced level was officially put into operation in Guangxi Yuchai.
The heavy-duty diesel engine test line with an investment of 220 million yuan has an area of ​​more than 16,000 square meters. It costs only 140 million yuan to import equipment. The major equipment is imported from Europe. The production line has extensively used online measurement, online collection, dynamic information management system, PMS (production management system), QDM (quality management), and PMS system to realize the entire process monitoring from production to production.
This test line innovatively uses a number of advanced process designs, introduces four advanced assembly lines from Germany, uses the current world's popular internal and external assembly lines, and is equipped with advanced on-line inspection, semi-automatic assembly equipment, quality and production management systems, and adopts advanced semi-finished product spray paints. The process, ABB robot automatic spray paint, not only to improve the working environment of the operator, but also to improve the appearance of the product quality; AGV car for the first time the introduction of transport, to improve safety and save equipment space, but also greatly improve the transport efficiency. The pre-assembly line of the trial machine bears the installation and inspection of related tooling and auxiliary parts before the test machine, realizes centralized management, reduces the auxiliary time of the gantry crane, and improves the utilization rate of the gantry up to 30%.
In addition, in every post of the assembly, the system automatically presents the station information, such as the online detection of the protruding height of the cylinder sleeve, the accurate positioning and measurement of the crankshaft, the automatic reversal, the automatic camshaft, the automatic tightening, and the on-line measurement integration. The stability of parts and quality is controlled. The automatic and semi-automatic degree of the entire production line has reached more than 50%, which will greatly reduce the labor intensity of workers and increase production efficiency. It is currently the most advanced heavy-duty diesel engine test production line in China. Its successful production has accelerated Yuchai's determination to lead the development of heavy machinery and is a new growth point for Yuchai to accelerate its development.
Tungsten Carbide Grits
Tungsten carbide grits are small particles or granules of tungsten carbide, a compound made up of tungsten and carbon atoms. They are extremely hard and have a high resistance to wear and abrasion, making them useful in a variety of industrial applications.
Tungsten carbide grits are often used as abrasives in cutting tools, grinding wheels, and sandpaper. They can also be used as an additive in metal alloys to improve their hardness and wear resistance. Additionally, tungsten carbide grits are used in the mining and drilling industry for rock drilling and excavation.
These grits are available in different sizes and shapes, such as spherical or irregular particles, depending on the specific application. They are typically produced through a process called sintering, where Tungsten Carbide Powder is heated and compressed to form a solid material.
Overall, tungsten carbide grits are highly valued for their hardness, durability, and resistance to wear, making them essential in various industries where high-performance materials are required.
