Vertical axial flow pump pump body pipe system basically can be divided into two types: one is the length of the pump is fixed, the water pipe is also fixed to 60 degrees. The transmission device of the pump is separated from the chestnut body and is connected with the intermediate transmission shaft. The other is a pump body length of pipe is according to the head of the need to design, between the pump and the power machine using a direct drive. To improve the pump inlet conditions, reduce water loss, improve the anti cavitation performance, small vertical shaft tube often made of streamlined flow pump suction bell, bell is generally made of cast iron. The suction tube of the large and medium-sized chestnut and the foundation of the chestnut stand are poured into the whole by the reinforced concrete, and the elbow shaped water inlet pipe is made. Run time also need the following several points:
1.Try to run, should check the link parts, ensure that the connection parts no loosening phenomenon.
2.Electrical, instrument work is normal, oil, gas, water, the system pipeline must not leak; pressure, hydraulic normal.
3.Check whether there is floating near the water inlet, water inlet to prevent clogging.
4.Axial flow pump rolling bearing temperature should not be greater than 75 degrees.
5.At any time to pay attention to the sound and vibration of the pump, found abnormal immediately stop inspection.
6.The gear box oil temperature should be normal.
