In recent years, due to climate reasons, large and medium-sized cities across the country have experienced heavy rainfall in flood seasons. Heavy rainfall or continuous rainfall exceeds the design standards of urban drainage systems or water accumulation in urban streets due to blockage of drainage system networks. Flooded disasters have emerged, and the flood control departments of various cities are also on the rise in demand for flood control pumps.
In the rainy season,flood control dewatering pump is indispensable. It belongs to a subtle combination of submersible motor and double suction pump, which not only has the function of submersible electric pump, but also has the special performance of double suction pump with high efficiency and stable operation. Applicable to low-lying drainage in the community, puddle drainage in the plant area, sewage discharge, river water extraction. The flood control drainage pump adopts the diesel engine to drive the axial return external mixing type, and through the unique design of the pump body and the impeller flow passage, it is not necessary to install the bottom valve and the irrigation water when using. The pump unit can absorb and contain large particle solids and long fiber impurity liquids, and can be widely applied to municipal sewage and flood control projects, agricultural irrigation and the like.
The flood control drainage pump is flexible and maneuverable, and the equipment is integrated with driving power. It can be used for emergency rescue and rescue in power-free areas. When the equipment is on the scene, use the control system installed to start the engine to drive the pump to pump the fluid, which is convenient and quick. Each piece of equipment is independently movable, without any auxiliary engineering, maneuvering, and arriving at any time. The flood control drainage pump can be installed and operated in a short time by a single person, without additional power supply and lifting equipment, and no complicated maintenance.
1. There is a water leakage probe in the oil chamber. When the mechanical seal on the water pump side is damaged, the water enters the oil chamber, and the probe sends a signal to protect the pump.
2, can meet the requirements of high lift applications, because the mechanical seals are operating under negative pressure, with higher stability. The mechanical seal adopts double-channel series sealing. The material is hard and corrosion-resistant tungsten carbide. It has the characteristics of durability and wear resistance, which can make the pump run safely for more than 10,000 hours.
3. The double lower water absorption structure has low water absorption position. Because of the double suction type double flow channel single volute structure, the motor has no axial pulling force, which reduces and balances the light direction force, greatly improves the service life of the pump by 3 times and improves the life. The use efficiency is 15%.
4, the use of large flow channel anti-blocking component design, greatly improve the ability of dirt to pass, can effectively pass shorter fiber material and smaller diameter solid particles.
5, compact structure, small size, easy to move, easy to install, no need to build a pump room, can work in submerged water, greatly reducing the project cost.
