    Description

    Introduction

    IR horizontal single stage single suction water centrifugal pump, IS the national joint design of energy saving pump, it IS the BA type, BL type and other single stage water centrifugal pump more new.  The advantages are: the whole series of hydraulic performance layout is reasonable, the user choice range is wide, convenient maintenance;  Efficiency and suction reach the international average advanced level.  This type of pump is suitable for industrial and urban water supply, drainage, also can be used for agricultural drainage and irrigation and supply and transport of water or physical and chemical properties similar to water of other liquids, the temperature is not high 80℃.

    Head: 3.6-133 - m

    Traffic: 3-460 - m after/h

    Inlet diameter: 50-200mm

    Speed: 2900r/min and 1450r/min

    Medium temperature: IS "80℃, IR" 104℃

    Feature

    • IS type horizontal single stage single suction water centrifugal pump according to the international standard ISO2858 stipulated performance and size design, mainly by the pump body, pump cover, impeller, shaft, seal ring, shaft sleeve and suspension bearings.
    • IS, IR type horizontal single stage single suction water centrifugal pump pump body and pump cover part, IS divided from the back of the impeller, which IS usually referred to as the rear door structure form.  Its advantage is convenient maintenance, maintenance does not move the pump body, suction line, discharge line and motor, just remove the lengthening coupling of the middle connector, you can exit the rotor part for maintenance.
    • The pump shell (that is, the pump body and pump cover) constitute the pump studio.  Impeller, shaft and rolling bearings for the rotor pump.  The suspension bearing component supports the rotor part of the pump, and the rolling bearing is subjected to the radial and axial force of the pump.
    • In order to balance the axial force of the pump, most of the impeller of the pump are provided with a sealing ring before and after, and a balance hole is arranged on the back cover of the impeller. Because some axial force of the pump is not large, the back of the impeller is not equipped with a sealing ring and balance hole.
    • The axial seal ring of the pump is composed of packing gland, packing ring and packing, in order to prevent air intake or a lot of water leakage.  If the impeller of the pump is balanced, the cavity with soft packing is communicated with the impeller inlet. If the liquid at the impeller inlet is in a vacuum state, it is easy to enter the air along the surface of the sleeve. Therefore, the packing ring is installed in the packing chamber through the hole on the pump cover, and the pressure water in the pump chamber is led to the packing ring for sealing.  If the impeller of the pump has no balance hole, because the liquid pressure on the back of the impeller is greater than atmospheric pressure, there is no leakage problem, so you can not install the packing ring.
    • In order to avoid shaft wear, the shaft through the packing chamber part is equipped with shaft sleeve protection.  There must be an O-ring between the bushing and shaft to prevent air intake or leakage along the mating surface.
    • The transmission mode of the pump is connected with the motor by lengthening the elastic coupling. The rotation direction of the pump is clockwise from the driving end.
