The new type of hydraulically controlled synchronous dual-drive hydraulically self-controlled flap gate adds a hydraulic hoist system on the basis of the original flap gate, enabling it to be safely opened and closed at any water level. Moreover, without starting the hydraulic system, it can still be normally opened and closed after reaching the corresponding water level.
This product has four major advantages:
1. Excellent switch control system. This product can be safely opened and closed at any water level. Without starting the hydraulic system, it can still be normally opened and closed after reaching the corresponding water level. During the operation of the gate, it can be smoothly opened and closed under the action of water power and self-weight, and the gate can also be opened or closed at will with the help of the hydraulically controlled synchronous start-up system.
2. Superior hydraulic control system. The hydraulic cylinders of the flap gate have a damping effect, which can effectively eliminate the flapping and instability during the operation of the flap gate. The problems of water leakage, maintenance caused by debris jamming, and the difficulty of silt cleaning are solved through hydraulic control.
3. Excellent overall operation performance. The hydraulically controlled synchronous start-up system of the dual-drive hydraulically self-controlled flap gate is added on the basis of the *** type flap gate, and its performance is more reliable and safer during operation.
4. High economic and social benefits. This product can *** improve the self-safety of the project, is easy to manage, has a long service life and low investment cost. It saves 30% of the investment compared with the lifting gates of the same scale. This technology has been successfully put into use in Santiao Power Station in Zhejiang Province, Wenfeng Power Station in Jiangxi Province, Songjiang River Scenic Area in Sichuan Province, Kaiyuan Hydropower Station in Guizhou Province, Heba Power Station in Fujian Province, etc., and has also been widely promoted in other provinces and cities. Its operation effect is consistent with the design result, meeting the design requirements and having a good use effect, which is well received by users.
Advantages in maintenance:
1. The oil cylinders of the bidirectional water-retaining hydraulic dam are enclosed between the two gate panels and are also enclosed by the side walls on both sides, so they are enclosed on all four sides. Although the piston rods of the oil cylinders are exposed outside, since they are protected on all four sides, the oil cylinders are not easily damaged. Generally, the seals only need to be replaced once every about 10 years.
2. There is a maintenance passage between the double panels. A water pump is designed in the maintenance passage. Once water enters the maintenance passage and reaches the designed water level, the water pump will automatically drain water to prevent the oil cylinders from being corroded due to long-term immersion in water, thus prolonging the service life of the oil cylinders.
3. The anti-rust paint used for the hydraulic dam panels is a new type of material, polyurea anti-rust paint, and its service life can generally reach about 10 years.
What contents are included in the appearance and shape inspection of the hydraulic dam?
As we all know, the hydraulic dam, that is, the hydraulic concrete lifting dam, is a relatively simple movable dam technology in water conservancy science and technology. It is widely used in the construction of agricultural irrigation, fishery, ship locks, seawater tide blocking, urban river landscape projects, and small hydropower stations. So, how to inspect the appearance and shape of the hydraulic dam?
First of all, it is necessary to meet the technical requirements in the drawings and tender documents, as well as the requirements of other technical specifications in DL/T5018-94 "Code for Manufacturing, Installation and Acceptance of Steel Plate Gates for Water Resources and Hydropower Projects". Provide users with qualified and high-quality products and high-quality services to ensure user satisfaction. Hebei Yangyu Hydraulic Machinery Co., Ltd. strictly implements the ***9000 quality management system for product quality control. According to the structural characteristics of the products, the following quality control processes are formulated:
1. Process control
2. Quality control of process work
3. Quality control of blanking
