  • 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

  • Installation steps of vertical axial flow pump

    Axial flow pumps are usually upright, and the centrifugal impeller is submerged under water, and it is also a vertical or side axial flow pump. The leaf-type axial flow pump has two types of structure: movable and adjustable. The application load (the key is the total flow rate) of large and medium-sized axial flow pumps often needs to be changed greatly during operation. Adjusting the installation angle of the leaves allows the pump to maintain high efficiency operation under different loads. Small and medium pump

  • How to maintain and repair the mixed flow pump?

    So that you can apply mixed flow pumps more strongly, our company will bring you some professional knowledge about maintenance and repair of mixed flow pumps. In the first place, how to maintain a mixed flow pump that is not used. When your mixed-flow pump is not at the service life, you should immediately protect the mixed-flow pump from water resources. The price of the mixed-flow pump exhausts the water stored in the pump, especially in winter, and then put it in a dry place.

  • Basic knowledge of mixed flow pump

    Mixed flow pump is a kind of pump between centrifugal pump and axial flow pump. As far as its working principle is concerned, it relies on the dual effects of axial thrust and centrifugal force on the liquid by the impeller rotation. The liquid flows into the impeller in the axial direction and flows out of the impeller in the form of oblique flow. Therefore, the mixed flow pump is also called an oblique pump. The characteristic of mixed flow pump is that the flow is larger than that of centrifugal pump, but smaller than that of axial flow pump; the lift is higher than that of centrifugal pump

  • Three directions for the development of China's water pump industry

    In this era of rapid development of science and technology, pump products must also have a certain development path and direction. (1) Development of the integration of machinery, electricity, and instrumentation. Metering pump products, whether they are general-purpose pumps such as small household pumps, construction pumps, or process pumps for large-scale petrochemical, electric and other industrial installations, are moving towards machinery, The continuous development of electricity and instrument integration makes pump products more efficient

  • Axial flow pump running trajectory

    The operation of the axial flow pump includes filling, starting, running and stopping. Compared with the centrifugal pump, the axial flow pump is different in structure. The axial flow pump has its special place. Today, Xiaobian introduces the running trajectory of axial flow pumps: medium and small axial flow pumps, especially horizontal axial flow pumps or small vertical axial flow pumps, are mostly installed above the water surface, so it should be installed before starting. ,Pump

  • How to install horizontal axial flow pump

    1. Check whether the pump shaft and transmission shaft are bent due to transportation, and straighten if necessary. 2. The installation elevation of the horizontal axial flow pump must be as specified in the installation diagram to meet the requirements of cavitation margin and starting. 3. Before the water enters the pool, a pollution barrier should be provided to prevent debris from being brought into the horizontal axial flow pump. The velocity of the water passing through the pollution barrier should not exceed 0.3 m / s. 4

  • Causes of water leakage from the pump

    Reasons for water leakage of the pump (1) When the water pump is installed, the water seal seat assembly is not installed in place, causing the pump to continue to leak water. Because the pump shaft corresponding to the inspection hole has a water blocking (flicking) ring, when the water seal leaks, the cooling water will be thrown out and dripping out of the pump's viewing hole when it encounters the water blocking ring along the pump shaft. Cooling water flows into the bearings to damage lubrication. Also, do not pay attention when changing the water ring

  • How to improve pump corrosion protection

    The anticorrosion and heat preservation of the pump are very important for the work of the pump. Everyone knows that most of the pump's delivery medium is corrosive, and the temperature of the medium is different, and the degree of corrosion is different. How to improve the anticorrosion and heat preservation effect of the pump? Anti-corrosion is the primary problem of the pump. During the use of the fluoroplastic pump, it must be carried out according to the operating rules. This can improve the working efficiency and service life of the pump.
