The chemical structure of the axial flow pump plan features

chemical characteristics of axial flow pump

1, chemical axial-flow pump large total flow, low pump head. Chemical axial flow pump impeller generally immersed in a liquid, and thus do not need to take into account the cavitation, launched without irrigation pump.

2, the practical area of high power category, in two head high power rating point.

3, with the centrifugal water pump, chemical axial flow the less traffic, the greater the shaft power, and therefore should be starting open valve.

chemical structure of the axial flow water pump plan

1, the motor cooling

( 1) The cooling medium of the motor can be pump transporting by liquid or other cooling medium.

( 2) Was transporting pump liquid such as cooling medium and external piping, piping system produced by the pump manufacturer supply, and put them completely assembled in pump, piping system planning and equipment can be removed for cleaning and repairing. Piping material transport liquid and environmental conditions caused by corrosion resistance.

2, motor sealing

chemical axial flow pump cavity sealing between the inner cavity pump cavity with a motor and motor set between inner cavity and reliable sealing devices, to prevent the pump delivery by the liquid into the motor chamber.

3, critical speed

under the condition of operation, all the rotor pump at the top of the practice of lateral critical speed of at least 10% higher than that the rotational speed of motor line

4, sealing ring

sealing ring after the equipment is reliable to determine without tumbling, fitted with the sealing ring is replaceable.

5, impeller

choose closed impeller, open or half open structure, according to use planning into a single port or multistream way; When the pump delivery by the medium fit the rules, the structure of the impeller can maintain jams, solid particles to prevent rotation when the circumferential and axial direction of movement.

chemical axial-flow pump hydraulic type blade scheduling organization is the result of hydroelectric generating set scheduling structure, with the advantages of large output torque, but sometimes oil system software, the blade installation Angle of scheduling due to scheduling organization omissions credibility relative weaker, is gradually replaced by a variable speed than scheduling, speed is very high, if the motor power, impeller diameter, large pipe diameter, flow can be very big.

1, the chemical structure of axial flow pump is compact, integration, pump and small volume. Its vertical structure has the equipment cover an area of an area small, smooth operation, equipment do not need to adjust.

2, planning into the same flange pump imports and exports, and in the same center online, facilitate pipeline layout, equipment for lunch.

3, pump and motor coaxial, short axial dimensions, make the pump work more stable, low noise.

4, to prevent the chemical axial-flow pump transporting medium leakage, thus has obvious characteristics of completely without leakage.
