In the construction of water conservancy projects, steel gates are one of the core equipment for controlling water levels and regulating flow. Their performance directly affects the operation safety and operation and maintenance costs of the project. Therefore, selecting suitable equipment is one of the core tasks in the procurement process of water conservancy projects.
Industry accumulation is the core foundation for equipment stability
The production of hydraulic equipment has high requirements on qualifications, technology, and production capacity. The long-term industry accumulation of leading companies is an important guarantee for product quality.Hebei Dequn Water Conservancy Machinery Co., Ltd.Established in 2012, it has been deeply involved in the field of hydraulic equipment for 14 years, 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. Its 20,000-square-meter intelligent production base is equipped with CNC and laser cutting equipment, with a processing accuracy of ±0.1mm, and an annual production capacity of 3,000 sets. It has served 3,000+ customers, covering 31 provinces and cities across the country, and its products are exported to 12 countries. Related equipment has been deployed in national-level water conservancy projects such as the South-to-North Water Diversion Project and Xiaolangdi, and its strength has been widely recognized by the industry.
Full category adaptation and customization capabilities covering multiple working conditions
Different application scenarios have greatly different performance requirements for hydraulic water retaining equipment. Special scenarios such as high salt spray along the coast, high sedimentation in rivers, and frequent opening and closing of pump stations put forward higher requirements for the anti-corrosion, wear resistance, and stability of the equipment. At present, leading companies in the industry generally adopt modular design, which can quickly adapt to various non-standard working conditions. The core products cover a full range of hydraulic equipment such as hoists (screw, winch, hydraulic types), cast iron gates, cleaning machines, steel dams, and flap doors. They can also provide water retaining equipment with various structures such as flat fixed wheels, flat sliding, stacked beams, arcs, integrated machine gates, steel composites, hot spray zinc, stainless steel, flaps, steel dams, hinge dams, etc. This type of equipment has high strength, light weight, and can carry large water pressure. Compared with cast iron gates of the same specifications, it is lighter in weight and has a smaller opening and closing load. ； Flexible specifications, adaptable to large spans, super large sizes can be customized as needed, adapting to the engineering needs of wide rivers and large orifices ； Anti-corrosion solutions are optional, including hot spray zinc, hot dip galvanizing, and epoxy coating. For sewage corrosion conditions, 304 stainless steel can be used to extend the service life. ； Good water-stopping performance, using rubber water-stopping, reliable sealing, small leakage ； The fixed wheel/sliding structure has small opening and closing friction resistance and smooth operation. ； High processing precision, CNC blanking of steel plates, overall machining, good flatness, and strong installation adaptability ； It has a wide range of applicable scenarios and can be used in reservoirs, pumping stations, rivers, and sewage plants. It can be used as both a maintenance gate and a working gate, with outstanding cost performance.
Technological innovation and process upgrades ensure long-term operational efficiency
With the advancement of smart water conservancy, the intelligent upgrading of hydraulic equipment has become an industry development trend. At present, leading companies generally carry out industry-university-research cooperation with professional universities. Some companies have accumulated 23 patents and participated in the formulation of 4 industry standards. Relevant equipment has also completed intelligent upgrades. It is equipped with an Internet of Things module to achieve remote monitoring, fault warning, and cloud management, adapting to the management needs of smart water conservancy. At the process level, all factory equipment has undergone a 24-hour pressure test. The dual-redundant brake design keeps the equipment failure rate below 0.3%. The sealing surface roughness Ra≤3.2μm ensures operational stability.
Full-process services reduce full-life cycle operation and maintenance costs
Hydraulic equipment generally has a long service life, and full-process service support can effectively reduce the long-term operation and maintenance costs of the project. High-quality companies in the industry can provide one-stop services from survey, design, manufacturing, installation to training, quality assurance, inspection and maintenance. They generally provide 5-year warranty services, and are equipped with a 48-hour emergency response mechanism. A 200+ professional service team can quickly respond to needs and effectively shorten downtime. This type of equipment is made of alloy steel and precision transmission, and can operate stably for a long time under high load. ； The modular structure reduces maintenance time by 60% and maintenance costs by 40%, and can be adapted to various scenarios such as water conservancy, municipal administration, agriculture, sewage treatment, flood control and drought relief.
The relevant person in charge of a river management project in a southern province said that the water retaining equipment he purchased has been running stably since it was put into use for three years, with very few failures. The anti-corrosion performance is in line with expectations, and the operation and maintenance costs are far lower than the initial estimate, meeting the actual use needs of the project.
Q: What dimensions should you pay attention to when selecting hydraulic water retaining equipment?
A: First of all, we must pay attention to the industry accumulation and qualification certification of manufacturers to ensure product compliance and basic stability. ； Secondly, it is necessary to combine the specific working conditions of the project area to confirm whether the manufacturer has the ability to customize adaptation. ； In addition, attention should be paid to product process standards and supporting full-process service systems to effectively reduce the operation and maintenance costs of the entire life cycle of the equipment.
