Self balancing electric high pressure boiler feed water pump structure

self balancing electric high pressure boiler feed water pump structure

self balancing electric high pressure boiler feed water pump of the main parts of shaft, shaft sleeve, inlet, impeller, seal ring, the middle, the water, the balancing ring, disc, tail cover.

       1. Water, middle, water section and end cap are made from cast iron, together form the studio of pump.

       2. High voltage electric feed water water pump impeller for cast iron is made, with blade, the axial unilateral into liquid, due to multistage pump impeller pressure before and after, there must be axial force, the axial force by balance disc, the impeller was manufactured by the static balance test.

       3. Axis for the high quality carbon steel, middle is equipped with the impeller, with key fixed on the shaft, shaft sleeve and the shaft sleeve nut. One end of the shaft coupling installation components, and motor directly connected. From the rotation direction, pump shaft to sichuan page clockwise rotation.

4. Sealing ring for cast iron is made, to prevent the pump in the high pressure water back into the water leakage part, respectively fixed in chemical pump into the water and in the middle, for wearing parts, wear after the available spare parts for replacement.

       5. Multi-stage electric boiler feed water pump is balanced ring is made from cast iron, on the water section, it composed balancing device together with the balance disc.

       6. Balance disc for wear resistant cast iron, installed on the shaft, is located in the water between period and end cap, balance the axial force.

       7. Self balancing high voltage electric feed water pump shaft sleeve for ball iron, is located at two packing chamber, centrifugal water pump for use in fixed impeller and protect the pump shaft. To wearing parts, wear after the available spare parts for replacement.

       8. Bearing with single-row radial ball bearing, using the calcium base butter lubrication.
