  • What are the characteristics of axial flow pumps?

    Axial flow pump centrifugal impeller is equipped with 2 to 7 leaves and rotates in a round steel pipe-shaped pump body. The pump body at the upper end of the centrifugal impeller is equipped with a fixed guide vane, which is used to remove the rotating motion of the liquid, so that it becomes a radial fitness exercise, and changes the mechanical energy of the rotating fitness exercise into working pressure energy. & nbs

  • Features and applications of axial flow pump

    1. Use and management Axial flow pump is a kind of pump with high specific speed. Generally, the specific speed is 500 ~ 1000. Because the faster, the lower the head, the greater the flow. Because the QV-H performance curve of the axial flow pump is very steep, the valve in the discharge pipeline should not be closed when starting, otherwise the starting power will be too large, which will cause overload and damage to the motor. The axial flow pump uses an adjustable vane pump to regulate the flow.

  • Points to note when installing an axial flow pump

    The working area of the axial flow pump is also its design parameters, which are all within this design range. Therefore, pay attention to the following points when installing the pump: 1) The installation position of the pump should meet the requirements of the allowable suction height. The foundation must be level and stable to ensure that the rotation direction of the power machinery is consistent with the rotation direction of the pump. 2) When the water pump and power machine are connected by shaft, the shaft must be ensured.

  • Introduce the starting operation of axial flow pump

    Axial flow pump starting operation: 1. Start the oil pump. Pay attention to whether the steering of the pump shaft is correct. 2. Pay attention to the readings of the pressure gauge and vacuum gauge. After starting, when the readings of the pressure gauge and vacuum gauge are stable after a period of fluctuation, it means that the pump has been turned on.

  • How to maintain the axial flow pump everyday?

    Axial flow pumps must be filled with water when they are started, and have long-term contact with water during operation. Due to the influence of water quality, the working conditions of Dalian axial flow pumps are worse than that of fans. Therefore, the inspection and maintenance work has more content than fans. Higher than the fan. It is necessary to regularly check the Dalian axial flow pump and pipelines.

  • How to solve the problems that occur in the ultra-high lift operation of axial flow pumps?

    At present, small and medium-sized axial-flow pump stations (generally managed by towns and villages) with a large number and wide distribution in the country, with diameters below 1 meter, are weak in technical power, and it takes time and effort to adjust the angle (half-adjustment). Therefore, after the pumping station is put into operation, the normal operating range of the pump is rarely reviewed and adjusted according to the changes in operating conditions, resulting in waste of energy and unavailability of the pumping station.
