8-inch diesel engine pump for flood control materials

Gasoline (diesel) engine pumps are used for drainage tasks in emergency rescue operations. Flow rate ≥ 100m3/h, head ≥ 20m, power ≥ 15kW, gasoline and diesel drive, outlet hose ≥ 100m, including accessory package.

Self suction principle of suction pump: Due to the special design of the pump casing. Its sealing performance is higher than that of ordinary centrifugal pumps, and the water in the pump casing will not automatically drain after the motor is stopped. The motor drives the turbine to rotate at high speed, quickly creating negative pressure (vacuum) inside the pump. Utilize atmospheric pressure to pressurize the pump casing, and then centrifuge the head. So, the suction stroke of the self-priming pump will not exceed one atmosphere

1、 In the summer of 2023, the 'Steel Guardian' in flood control and rescue operations experienced historic heavy rainfall in North China. In an industrial park in Zhuozhou, Hebei Province, three high-power diesel self-priming pumps worked continuously for 72 hours, with a cumulative drainage volume of over 150000 cubic meters, successfully preserving production equipment worth billions of yuan. This typical case confirms the irreplaceability of diesel self-priming pumps in flood control. Compared with traditional electric pumps, diesel engine driven self-priming pumps have significant advantages: they do not require an external power source and can still operate normally in disaster areas with power outages; The self-priming height can reach 4-6 meters, and it can quickly extract accumulated water from deep pits; The flow range varies from 20m ³/h to 800m ³/h, which can meet the drainage needs of different scales. In recent years, the diesel self-priming pump has played an important role in the '7.20' extremely heavy rainstorm in Zhengzhou and the floods in the Yangtze River basineffect. 2、 Core technology analysis: Why it has become the core competitiveness of flood resistant diesel self-priming pumps lies in its unique working principle. Adopting a combination design of centrifugal pump and vacuum assisted system, only a small amount of water needs to be injected into the pump body before starting. When the diesel engine drives the impeller to rotate at high speed, a vacuum is formed in the inlet pipeline, and atmospheric pressure is used to inject water into the pump body, achieving rapid self-priming. The actual test data of a 6-inch caliber diesel self-priming pump from a certain brand shows that it only takes 30 seconds from start-up to water discharge,The biggestLift of 28 meters, processing capacity of 400 cubic meters per hour. This efficient performance makes it particularly suitable for emergency drainage in basements, tunnels, underground garages, and other scenarios after floods.
