A concrete limited company located in Guangzhou is a key pre mixed concrete production enterprise in the region, with an annual output of over one million cubic meters of high-quality concrete. It supplies C30, C50, and even C80 high-grade concrete to surrounding municipal roads, high-rise buildings, industrial parks, and other engineering projects year-round. With the continuous increase in business volume, the number of concrete test blocks that need to be tested in the laboratory of this station has significantly increased every day, which has put forward higher requirements for the tonnage, efficiency, and stability of the testing equipment.
With the increasing number of large-scale engineering projects undertaken, the original 200 ton pressure testing machine of the mixing plant is gradually becoming inadequate
1. Insufficient measuring range: When testing high-strength concrete test blocks above C60, the data accuracy is difficult to guarantee due to approaching the upper limit of the equipment, and long-term full load operation affects the service life of the equipment.
2. Efficiency bottleneck: The testing task of dozens of sets (3 blocks per set) of test blocks per day, traditional equipment can only hold one block at a time, frequent sample changes, repeated pressurization, and the testing personnel often accumulate test blocks even after "continuous rotation".
3. Data management lag: manual recording and manual calculation of reports are not only inefficient, but also difficult to meet the strict requirements of quality traceability for large-scale projects.
In response to the above pain points, technicians from Jinan Xinguang recommended the YAW-3000 300 ton microcomputer controlled electro-hydraulic servo pressure testing machine to the station. This device perfectly matches the upgrading needs of the mixing plant with its large tonnage, high precision, and intelligent characteristics:
1. With sufficient tonnage margin, high-strength concrete can easily cope: the equipment test force reaches 3000kN (300 tons), and the range fully covers the compressive strength testing of C30-C80 and even higher grade concrete. There is no need to worry about overloading, and the testing data is more accurate and stable. At the same time, sufficient space has been reserved for future projects involving ultra-high strength concrete.
2. Electric screw adjustment, doubling the efficiency of batch testing: The equipment uses an electric screw to adjust the compression space, without the need for manual shaking of the handwheel, making specimen placement faster. In response to the demand for batch test block detection in mixing plants, the equipment supports continuous loading and automatic return, greatly reducing the single block detection cycle. Combined with a 370 × 370mm large-sized pressure plate, it can easily accommodate various standard test blocks.
3. Fully automatic intelligent control, data traceability: equipped with a microcomputer control system and Lenovo brand computer, it can achieve automatic completion of constant stress loading tests. Each experiment data is automatically collected, stored, and standardized test reports are generated, supporting data upload and meeting the requirements of modern laboratory information management. Simultaneously equipped with safety protective covers to ensure the safety of operators during high-intensity testing.
4. Stable and reliable, fearless of high-intensity continuous operation: using high-precision sensors and electro-hydraulic servo technology, the loading rate can be digitally set (such as 1500N/s), and the loading process is smooth and controllable. The host weight of around 1800kg ensures the stability and durability of the equipment under high-frequency and high-intensity continuous operation.
Customer testimony: "Since I started using this 300 ton press machine from Xinguang, I have been able to handle as many high-strength test blocks as possible. More importantly, the efficiency has been significantly improved with electric adjustment and automatic constant loading. With the same amount of manual labor, the number of test blocks processed per day has nearly doubled, and the data is directly reported. Even when the owner came to inspect, they said that our laboratory has been upgraded
