The assessment IS spot supply, ISR80-50-315 - c water centrifugal pump

IS a centrifugal pump of pump body and pump cover, from dissection of the impeller, known as the open structure. Its advantage is simple maintenance, overhaul pump body, when the suction pipe, the discharge line and motor, simply remove the lengthened coupling in the middle of the connection piece, can exit the rotor parts, for maintenance.

Of the pump shell (i.e., pump body and pump cover, impeller, pump studio axis and rolling bearing as the pump rotor. Suspension bearing parts supporting the pump rotor parts, rolling bearing radial force and axial force of pump.

To balance the axial force of pump, most of the pump impeller have before and after sealing ring, and is equipped with balance on impeller HouGaiBan hole, because some pump axial force is not big, the impeller did not set a seal ring and balance holes on the back.

Pump axial sealing ring is composed of packing gland and packing and so on, in order to prevent the air intake or a large number of leaking. Pump impeller balance, if any, is equipped with soft packing cavity and impeller inlet are interlinked, if at the entrance of the impeller liquid in the vacuum state, then it is easy to along the inlet shaft sleeve surface, therefore in the packing chamber with a packing ring through the small hole on the pump cover indoor pressure water pump to packing ring seal. Pump impeller, such as no balance hole, because the liquid pressure is greater than the atmospheric pressure on the back of the impeller, so there is no leak problem, so don't put packing ring. To avoid axis wear, at the site of the shaft through the packing chamber with a collar protection, between the shaft sleeve and the shaft is equipped with type sealing ring, in order to prevent the surface along with air intake or leaking.

Pump transmission way is through the extended elastic coupling and motor coupling. The direction of rotation of the pump, look from the driving end, to turn clockwise.
