Description

Technical Field

[0001] This invention originates from fluid mechanics and Bernoulli's principle, and relates to the field of automatic "liquid-gas energy" lifting technology. Specifically, it is a group water hammer pump water lifting system with adaptive flow regulation function and a multi-stage, multi-layer circulating water lifting device system. Background Technology

[0002] A water hammer pump is a device that utilizes the water hammer effect, created by a certain drop in elevation, to lift water from a lower elevation to a higher one by alternating valve closures. It has applications in water conservancy projects and agricultural irrigation. However, traditional water hammer pumps are mostly single units or simple combinations, resulting in low installation space utilization, insufficient water lifting efficiency, and inconvenient maintenance. To solve these problems, there is an urgent need for a structurally optimized, highly efficient, stable, and high-flow-rate method using a cluster of water hammer pumps. Summary of the Invention

[0003] The purpose of this invention is to provide a group water hammer pump water lifting scheme, which changes the original single water hammer pump to a multi-level, multi-layer group array, with adaptive adjustment of water flow circulation and water hammer effect to achieve the water lifting effect of single-layer array installation unit modules, multi-layer three-dimensional installation modules, and group large flow output. It can effectively improve space utilization and operating efficiency, and facilitate maintenance and replacement.

[0004] This invention employs a five-layer stacked installation, with each layer consisting of 33 interconnected pump arrays forming a unit module. Each unit water hammer pump module is equipped with a high-pressure energy storage tank on its upper part, totaling 165 sets of water hammer pump unit modules. After a single water hammer pump generates a water hammer effect, the outlet of the upper high-pressure energy storage tank connects to the interface of the top main high-pressure energy storage tank. The outlet of the main high-pressure energy storage "liquid-gas energy" tank continuously delivers water to the high-altitude reservoir.

Detailed Implementation

[0031] 1. Power input stage: Water flows into the bottom channel through the high-level inlet at a flow rate of 0.5-2m / s, which drives the hydraulic drive valve A to open and form the initial flow path.

[0032] 2. Water hammer generation stage: When the flow velocity reaches the critical value of 0.8m / s, the water flow impact force overcomes the spring preload, causing the hydraulically driven valve A to close instantaneously, resulting in a sudden increase in pressure in the pipeline, with a peak pressure of up to 1.2MPa.

[0033] 3. Energy conversion stage: High-pressure water flows through the hydraulically driven valve B in one direction (opening pressure 0.8MPa) and enters the high-pressure energy storage tank. The air inside the tank is compressed to 1 / 3 of its initial volume, corresponding to a pressure of 3.6MPa. The kinetic energy of the water is converted into the internal energy of the air, with a conversion efficiency of 75%±7%.

[0034] 4. Water output stage: Once the pressure inside the tank stabilizes, the water output pipe opens (opening pressure 3.2MPa), achieving a pumping distance of 30-60 meters. When the pressure inside the tank drops to 0.8MPa, the hydraulically driven valve B automatically closes, completing one work cycle.
