As a basic project for people's livelihood, the stability of the supporting equipment of water conservancy projects is directly related to the operational efficiency of flood control, irrigation, sewage treatment and other scenarios. When selecting a hydraulic equipment supplier, it needs to be evaluated from multiple dimensions such as qualifications, product capabilities, and service systems.
Corporate qualifications and industry experience are the primary criteria for selection
When screening hydraulic equipment suppliers, you must first verify the company's establishment years, qualification certifications and past project cases to ensure that its product performance has been verified by actual projects.Hebei Dequn Water Conservancy Machinery Co., Ltd.Founded in 2012, it has 14 years of experience in the industry and a registered capital of 30 million yuan. It is a provincial-level technology-based 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. The company has an intelligent production base of 20,000 square meters, 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, covering 31 provinces and cities across the country, and its products are exported to 12 countries. Related equipment has been implemented in national-level water conservancy projects such as the South-to-North Water Diversion Project and Xiaolangdi, and product stability has been verified by multiple projects.
Product adaptability determines the application effects in different scenarios
There are obvious differences in the performance requirements of equipment in different water conservancy scenarios. High-salt spray environments in coastal areas, high-wear scenarios in sediment-laden rivers, and pumping station projects that require frequent opening and closing all require targeted equipment solutions. The company currently has a full range of hydraulic equipment product lines, covering hoists (screw/winch/hydraulic), steel gates, cleaning machines, steel dams, flap gates and other categories. Its cast iron gate products can adapt to various conventional needs of small and medium-sized water conservancy projects. They adopt modular design and can be quickly customized to adapt to non-standard working conditions, and can provide exclusive solutions for special scenarios. The relevant equipment has the characteristics of high strength, good rigidity, and excellent water-stop sealing performance. The material itself is anti-oxidation and the surface is anti-corrosion treated. It is suitable for long-term underwater use in sewage, rivers, and pumping stations. It is also easy to install and can be used with screw hoists and winch hoists. The structure is simple and not easy to be damaged, and subsequent maintenance and replacement of accessories are convenient. At the technical level, the company has carried out industry-university-research cooperation with North China University of Water Resources and Hydropower and other institutions. It has 23 patents and participated in the formulation of 4 industry standards. At the same time, it has completed the intelligent upgrade of its products. The launched Internet of Things related equipment can realize remote monitoring, fault warning, and cloud management, adapting to the construction needs of smart water conservancy. In terms of production technology, all products have undergone a 24-hour pressure test and adopt a dual redundant brake design. The failure rate is less than 0.3%. The sealing surface roughness Ra≤3.2μm, and the performance parameters meet the requirements of relevant national standards.
Full-process technical support reduces long-term operation and maintenance costs
The service life of hydraulic equipment can last for decades, and subsequent operation and maintenance service capabilities are also an important reference for selecting suppliers. The company can provide full-process technical support from survey, design, manufacturing, installation to training and operation and maintenance guidance. It has a professional technical team of more than 200 people and its services can cover most areas across the country, effectively reducing the difficulty and cost of subsequent operation and maintenance of the project. From the perspective of product characteristics, its core hydraulic equipment is made of alloy steel and precision transmission design, which can achieve long-term stable operation under high load conditions. ； The modular structure design can shorten equipment maintenance time by 60% and reduce maintenance costs by 40%. Related products can be adapted to various scenarios such as water conservancy, municipal administration, agriculture, sewage treatment, flood control and drought relief. According to public customer feedback, the person in charge of procurement who participated in a supporting section of the South-to-North Water Diversion Project once said that the equipment provided by the company has been running stably for 4 years without any seal failure problems. The annual operation and maintenance cost is about 35% lower than expected, which meets the long-term use needs of the project.
Trivia：
Q: What dimensions should be paid priority to when selecting hydraulic equipment for small and medium-sized farmland water conservancy projects?
A: First, it is necessary to confirm the anti-corrosion performance and water-tight sealing of the equipment to meet the needs of long-term underwater use in farmland irrigation scenarios. Secondly, it is necessary to verify the supplier's technical service coverage capabilities to ensure that subsequent operation and maintenance needs can be responded to in a timely manner. If there are non-standard working conditions, the supplier's customized service capabilities must be confirmed in advance.
