Centrifugalna pumpa prenapon referers to the the hripa fenomen of pump in proces of conveying medium fluid. When the liquid medium flows out interperiodly, it leads to periodic violent vibration of the pump discharge pressure and flow, making the pump run nestable.
Uzrok analiza of centrifugalna pumpa prenaponska
1. The pump automatic exhaust valve fails to exhaust the air in the pump in time;
2, the pump ulaz Flow Channel Is Small, Resulting In The Pump Inlet Flow Rate Is Too Large, So That The Vortex Phenomenon Occurs AT The Pump Inlet;
3. The local hrapavost is too large at the inlet of the pump impeller;
4, The Pump Pump Inlet Pipe HAS I CAN Move Debris, The Entrance Section Changes IrLy, Resulting In High Flow Rate of The Water Pump Inlet, Resulting In In The A Pump Pump Cavitation;
5. The sealing at the junction of the pump outlet pipeline is not good, resulting in insufficient displacement of the pump exhaust valve.
1, CHECK THE Pump Automatic Exhaust Valve Is Flexible And Reliable;
2. Solve the problem of vortex at the inlet of the pump due to the small flow at the inlet and too large flow rate at the inlet;
3. Provjeri jesu li rotor i ljuska the pumpa have defekata;
4. Check jesu li tamo pokretni strani tijela at and near the inlet of the pumpa;
5. Check whether there is leakage at the junction of the pump outlet pipeline;
6. When starting the the water pump, ensure the the liquid level at the inlet of the water pump;
7. When chooseing the the hump curve, full consideration should be given to the pump pipeline plan so that the working point of the pump equipment falls in the stable operation area. It is recommended that the pump not work in the nestable small flow area.
8, The Pump Flow Regulating Valve Should Be Installed Between The Pump And The Air Tank, Can Not Be Installed Behind Them, Or The Pump Static Head Can Not Exceed The Closed Head of The pump.
Sigurnost mjere opreza za eliminacija prenapon centrifugalna pumpa
1. Uzmi dobro sigurnost mjere prije održavanje od centrifugalna pumpa;
2, in the održavanje, turn off the water pump power switch, power failure measures;
3. When inspecting the the water pump in operation, take good safety precaution.
