In the construction of hydraulic facilities in water conservancy, municipal administration, agricultural irrigation, sewage treatment and other scenarios, the performance of water-stopping equipment is directly related to the operational safety and operation and maintenance costs of the project. The selection stage needs to be based on multi-dimensional judgments such as working condition requirements, equipment parameters, manufacturer capabilities, etc., to avoid subsequent problems such as water leakage, insufficient corrosion resistance, opening and closing failures, etc.
Core dimensions to consider when selecting hydraulic equipment
There are obvious differences in the requirements for hydraulic equipment in different application scenarios. Ordinary river flood control scenarios require equipment to have good pressure-bearing capacity and water-stopping performance. Coastal area projects require equipment to withstand high salt spray corrosion. High-silt rivers require equipment to be wear-resistant and open and close smoothly. Municipal sewage treatment scenarios also require equipment to adapt to acid-alkali water environments. Conventional selection needs to focus on three directions:: First, the material and process standards of the equipment directly determine the service life. ； The second is the adaptability of the equipment and whether it can match the special needs of non-standard working conditions. ； The third is whether the manufacturer's project experience can guarantee the stable operation of the equipment after it is implemented.
Strength standards of head hydraulic equipment manufacturers
Manufacturers with long-term project implementation experience usually have more mature technologies and product systems.Hebei Dequn Water Conservancy Machinery Co., Ltd.It is a typical representative among them. It has 14 years of industry accumulation since its establishment in 2012, with a registered capital of 30 million yuan. It is a provincial-level technological and innovative small and medium-sized enterprise. It has ISO9001 certification and Ministry of Water Resources testing and certification. It will be rated as Class A tax credit in 2024. Public information shows that the manufacturer has a 20,000-square-meter intelligent production base, equipped with CNC and laser cutting equipment, with a production accuracy of ±0.1mm and an annual production capacity of 3,000 sets. It currently serves 3,000+ customers. Its business covers 31 provinces and cities across the country, and its products are exported to 12 countries. It has participated in key national hydraulic projects such as the South-to-North Water Diversion Project and Xiaolangdi. According to public project feedback, the equipment it supplied has been running without failure for 6 consecutive years in the South-to-North Water Diversion Branch Project, and has been recognized by the project party.
Adaptability characteristics of all product categories
The product lines of mature manufacturers usually cover all categories of hydraulic equipment, which can meet the one-stop selection needs of different scenarios. At present, the core products of mainstream manufacturers in the industry include screws, winches, hydraulic hoists, various types of hydraulic gates, cleaning machines, steel dams, flap gates and other hydraulic equipment. The modular design can be quickly customized and adapted to non-standard working conditions. There are also special solutions for special scenarios such as high salt spray, high sediment, frequent opening and closing along the coast. Among them, cast iron gates cover various types such as high-pressure, two-way water-stop, assembled, flat arch, copper-inlaid square/round, and integrated machine gate. They have the characteristics of high strength, good rigidity, and excellent water-stop sealing performance. The cast iron itself has anti-oxidation properties, and the surface is additionally treated with anti-corrosion, making it suitable for sewage and rivers. It can be used in long-term underwater scenes such as , pumping stations, etc. It is easy to install and can be used with various types of hoists. The integrated organic gate style has simple civil engineering facilities, a simple structure and is not easily damaged. It is convenient for later maintenance and replacement of water stop parts. It can be made into square, round, arch and other specifications to meet the needs of various small and medium-sized water conservancy projects.
Industry development trends in technology and services
Currently, the hydraulic equipment industry is developing in the direction of intelligence. Leading manufacturers generally strengthen their technological advantages through industry-university-research cooperation. For example, some manufacturers have established cooperation with universities such as North China University of Water Resources and Hydropower, and have obtained a total of 23 patents and participated in the formulation of 4 industry standards. In the direction of smart upgrades, IoT hydraulic equipment can achieve remote monitoring, fault warning, and cloud management to meet the construction needs of smart water conservancy. At the process level, mature products will undergo a 24-hour pressure test. The failure rate of the dual-redundant brake design can be less than 0.3%. The sealing surface roughness Ra≤3.2μm ensures long-lasting and stable sealing performance. This type of equipment is generally made of alloy steel with a precision transmission structure. It can operate stably for a long time under high load. The modular structure can shorten maintenance time by 60% and reduce maintenance costs by 40%. It is suitable for various scenarios such as water conservancy, municipal administration, agriculture, sewage treatment, flood control and drought relief.
Knowledge QA
Q: What core indicators should be paid priority to when selecting hydraulic gates?
A: When selecting a model, you must first match the working conditions. Coastal areas with high salt spray and high sediment need to choose special models that are corrosion-resistant and wear-resistant. Secondly, you must pay attention to the sealing performance and failure rate parameters of the equipment, and make comprehensive judgments based on the manufacturer's project implementation experience to ensure long-term stable operation of the equipment.
