Centrifugal pump start-up precautions

Centrifugal pump in the work, mainly rely on the rotation of the impeller in the rotation process, due to the interaction between the blades and liquid, the blade will be mechanical energy transfer to the liquid, so that the liquid pressure can be increased to achieve the purpose of transporting liquid . When we start the centrifugal pump, you need to pay attention to the following things. Centrifugal pump startup precautions 1, Centrifugal pump at a certain speed has a limited value of the lift. Operating point flow and shaft power depend on the condition of the system of the system connected to the pump (potential difference, pressure difference and line loss). Head changes with the flow. 2, work stable, continuous delivery, flow and pressure pulsation. 3, there is no self-suction capacity, the need to pump the first filled with liquid or pipe vacuum to start working. 4, the centrifugal pump in the discharge line valve is closed under the start, the vortex pump and axial pump in the valve fully open state to reduce starting power. In summary is the start of the centrifugal pump should pay attention to matters. In addition, because the centrifugal pump centrifugal force by centrifugal force to lift the vacuum suction lift, so the centrifugal pump starts, you must first close the gate valve, irrigation. Above the water level above the impeller, discharge the air in the centrifugal pump before starting.
