  W ater P ump W holesale Pumps are usually used to lift liquids, to transport liquids or to increase the pressure of liquids, that is, the mechanical energy of the original motive can be changed into liquid energy to achieve the purpose of pumping liquid.   The technical parameters of water pump performance are flow, suction, lift, shaft power, water power, efficiency, etc. According to different working principle, it can be divided into volume water pump, vane pump. The volumetric pump uses the change of its studio volume to transmit energy; Vane pump is used to transfer energy through the interaction of rotary blades and water, with the centrifugal pump, axial flow pump and mixed flow pump.   Precautions for installation of best water pump 1. The basic coordinates, elevation, dimensions and reserved holes shall meet the design requirements. The basic surface level and concrete strength shall meet the installation requirements of the equipment. The plane size of the water pump founda

  Pump Wear Plate For users, the maintenance of daily use is more important to prolong their life, so the following two points must be done:   tighten the wear-resistant plate (ring) of the nut regularly. After the use of a period of time, there is a little wear on the wear-resisting layer due to the existence of abrasive wear in the braided concrete cylinder, so that a small amount of wear is made on the wear-resistant layer, and the loosening of the locking nut will appear. The thrust ring is not compressed without producing elastic force. There will be a certain gap between the wear plate and the wear-resisting ring. At this time, the fine particles in the concrete will enter the wear plate and the wear-resisting ring, forming a low-stress abrasion wear.   As the speed of wear is accelerated, the gap between the wear plate and the wear-resistant ring will become larger, making the large particles of concrete into the room, quickening the wear and scratch of the wear-resistant layer,

  S pare P art W ater P ump   Pump body: including suction chamber and the pressure chamber. Suction chamber: its function is to allow the liquid to flow evenly into the impeller. Pressure chamber: its function is to collect liquid and send it to a lower impeller or guide discharge pipe. At the same time, reduce the velocity of the liquid, so that the kinetic energy becomes pressure energy. The pressure chamber has two forms: volute and guide wheel. The volute is named for the spiral shape of the runner. The liquid flows along the spiral line. With the increase of the flow section, the velocity decreases and the kinetic energy becomes pressure energy.The guide wheel is commonly used in the segmented multistage pump. In order to make the structure simple and compact, the guide wheel is used to transform the energy between the primary impeller and the secondary impeller, and the liquid flows along the flow path specified by the guide wheel to the inlet of the secondary impeller.   Impell

  Classification of booster pump spare parts Generally, there are the impeller, bearing, sealing device, sealing material, main shaft, key, inducing wheel and other materials.   A pump is a machine that carries liquid or pressurizes the liquid. It transfers the mechanical energy of the original motive or other external energy to the liquid to increase the liquid energy. It is mainly used for conveying liquids including water, oil, acid lye, emulsion, suspension-emulsion and liquid metal, etc., it also can transport liquid, gas mixture and liquid containing suspended solids. The technical parameters of pump performance include flow, suction, lift, shaft power, water power, efficiency, etc. According to different working principles, it can be divided into volume water pump, vane pump type. The volumetric pump uses the change of its studio volume to transmit energy; Vane pump is used to transfer energy through the interaction of rotary blades and water, with the centrifugal pump, axial fl

  A multi-stage centrifugal pump is a collection of two or more centrifugal pumps that have the same functions. In the fluid channel structure, the performance in the first level of medium pressure mouth and second-level imports are interlinked, the second level of medium pressure and the third level of imports are interlinked, so formed multistage centrifugal pump parts   series of institutions. The significance of multi-stage centrifugal pump is to improve the setting pressure.   The structure of a multistage centrifugal pump assembly The multi-stage centrifugal pump is mounted on the same pump shaft with several impeller, and the outer part of the impeller is the liquid diversion device and the pump shell. According to the assembly method, there are two kinds: the horizontal split-type multi-stage centrifugal pump, which divides the pump body and the guide device along the axis of the pump shaft, making it into the upper and lower parts. The sectional multi-stage centrifugal pump cu

  The magnetic pump china  is a branch of the pump, and is a new product that applies the working principle of the permanent magnet coupling shaft to the centrifugal pump. In the production process of petroleum, chemical industry, pharmaceutical, printing and dyeing, electroplating, food, environmental protection, etc., it is used to transport corrosive liquid with no iron scrap.   The composition of magnetic pump Magnetic pump mainly consists of pump head, magnetic actuator (magnetic cylinder), motor, base and other parts. The magnetic actuator consists of an outer magnetic rotor, an internal magnetic rotor and a non-conductive isolation sleeve.   Working principle of magnetic pump When the motor drives the external magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic material, and drive the inner magnetic rotor connected with the impeller to rotate synchronously, realize the non-contact transmission of power and transform the dynamic seal into a sta

  Chemical centrifugal pump is widely used in various fields of chemical industry. Compared with other kinds of pumps, it has the advantages of simple structure, easy to wear, smooth operation, small noise, uniform water discharge, convenient adjustment and high efficiency. It is used sewage discharge in industrial, commercial, medical, environmental protection and other fields.   Classification of chemical centrifugal pump The impeller of the chemical centrifugal pump can be divided into the closed impeller, semi-closed impeller, open impeller and semi-open impeller. The flow direction can be divided into the radial flow, axial flow and mixed flow according to shape and liquid flow.   The working principle of the chemical centrifugal pump Before the start of the chemical centrifugal pump, the pumped liquid is filled in the pump shell. After start-up, the impeller is driven by the shaft and the liquid between the blades turns. Under the action of centrifugal force, the liquid is ejecte
