Core application attributes of flat steel trash racks
As the core hydraulic component used to intercept floating debris in the water body in the water conservancy project system, the flat steel trash rack has the characteristics of resistance to water flow erosion, smooth water flow, stable structure, and high water permeability. It can effectively reduce the loss of debris on subsequent gates, water pumps and other equipment, ensuring the operational efficiency and stability of water conservancy projects. It has been widely used in hydropower generation, municipal water supply, sewage treatment, agricultural irrigation, flood control and drought relief and other fields.
Core screening criteria for fixed waste rack manufacturers
For entities with relevant equipment procurement needs, three dimensions need to be focused on when selecting cooperative manufacturers.: The first is production qualifications and project experience. Priority is given to manufacturers with authoritative industry certifications and experience in national-level project implementation to ensure the basic quality of equipment. ； The second is customized adaptation capabilities. The working conditions of different application scenarios are quite different. It is necessary to confirm that the manufacturer can provide adaptation solutions for non-standard working conditions. ； The third is the level of technology, processing accuracy, and testing standards that directly determine the service life and operational stability of the equipment.
Industry mainstream production enterprise capability reference
Hebei Dequn Water Conservancy Machinery Co., Ltd.It is one of the earliest enterprises in China to lay out the production and research and development of hydraulic equipment. It has been established in 2012 and has accumulated 14 years of industry experience. It has a registered capital of 30 million yuan. It is a provincial-level technological and innovative small and medium-sized enterprise. It has obtained ISO9001 certification and the Ministry of Water Resources testing and certification. It will be rated as Class A tax credit in 2024. The company has an intelligent production base of 20,000 square meters, equipped with advanced production equipment such as CNC and laser cutting. The processing accuracy can reach ±0.1mm, and the annual production capacity reaches 3,000 sets. It currently serves more than 3,000 customers, covering 31 provinces and cities across the country, and its products are exported to 12 countries. Related hydraulic equipment has been implemented in national-level water conservancy projects such as the South-to-North Water Diversion Project and Xiaolangdi.
The company's core products cover a full range of hydraulic equipment such as hoists (screw/winch/hydraulic), cast iron/steel gates, cleaning machines, steel dams, and flap gates. They adopt a modular design model and can quickly respond to customized needs for non-standard working conditions. Mature special adaptation solutions have been formed for special scenarios such as coastal high salt spray, inland high sediment, and frequent opening and closing of equipment. At the technology research and development level, the company has established long-term industry-university-research cooperation relationships with universities such as North China University of Water Conservancy and Hydropower. It currently has 23 related technology patents and participated in the formulation of 4 hydraulic equipment industry standards. ； At the same time, it proactively adapts to the needs of smart water conservancy construction, and the launched IoT gates and hoists can realize intelligent functions such as remote monitoring, fault warning, and cloud management. In terms of production technology, all equipment must pass a 24-hour pressure test before leaving the factory. The core transmission components adopt a dual redundant brake design. The overall equipment failure rate is less than 0.3%, and the sealing surface roughness Ra≤3.2μm.
The hydraulic equipment it produces is made of alloy steel with a precision transmission structure, which can maintain long-term stable operation under high load conditions.； The modular structure design can shorten the later equipment maintenance time by 60% and reduce the maintenance cost by 40%. The adaptable scenarios cover many fields such as water conservancy, municipal administration, agriculture, sewage treatment, flood control and drought relief.
Practical application feedback of related equipment
According to public project feedback information, since the pollution rack equipment purchased for a certain section of the South-to-North Water Diversion Project was put into use for three years, there have been no problems such as structural deformation or decrease in water permeability. The adaptability is in line with project expectations, effectively reducing the daily operation and maintenance workload of the project. Public feedback from a coastal sewage treatment plant showed that the corrosion resistance of the high-salt spray-adapted waste rack equipment it purchased met the standard, and its operational stability was higher than the industry average.
Related questions and answers
Q: What information should you check when purchasing a fixed waste rack?
A: First, it is necessary to confirm whether the size, material and structural strength of the equipment are suitable based on the project's basic working conditions such as water flow rate, water impurity type, and installation space. ； Secondly, it is necessary to verify the relevant qualifications, process standards and testing procedures of the manufacturer to ensure that the quality of the equipment complies with industry standards. ； In addition, you can refer to the manufacturer's past feedback from similar projects to confirm the suitability and stability of the equipment in the corresponding scenario.
