Heavy rainfall drainage pump_Zhonglan rainfall drainage axial flow pump

Heavy rainfall drainage pump_Zhonglan rainfall drainage axial flow pump The characteristics of axial flow pump and mixed flow pump: belong to medium and large flow, medium and low lift. The lift of axial flow pumps is generally about - meters. In water supply and drainage projects, axial flow pumps and mixed flow pumps are widely used in urban rainwater pumping stations and large sewage pumping stations.
It can be built as an underground pumping station to maintain the environmental appearance of the ground. The use of submersible electric pumps is a thorough solution to the problems of building pump stations and flood control in areas along rivers and lakes where water levels fluctuate greatly. It eliminates the need for long shafts between pumps and improves operational safety and reliability.
The impeller is converted using the current advanced hydraulic model and has excellent, stable and mature performance. Choose a smaller D value to ensure better cavitation resistance and smooth operation. Two independent sets of mechanical seals isolate the motor and pump seals and are installed in series up and down to provide multiple insurances and improve reliability.
The oil chamber uses oil to lubricate and cool the seal to isolate the motor from the transported medium. The remaining volume can slow down the increase in pressure in the oil chamber. The reaction torque of the motor's starting torque at the moment the unit starts often causes the entire unit to rotate in the opposite direction. The anti-rotation device can solve this problem.
The bearing adopts rolling bearing which can bear all axial and radial loads and is completely separated from the medium transported by the pump. The pump and motor have a compact coaxial structure and the shaft extension is shortened as much as possible to reduce deflection due to design, minimize vibration during movement, seal and extend bearing life. High performance squirrel cage induction motors specially designed and manufactured to standards for submersible pumps. The insulation level is the highest and the operating temperature can reach ℃
