Vertical axial flow pump installation steps

axial flow pump is commonly pillar type, centrifugal impellers immersed in water inside, is vertical or lateral type axial flow pump. Pillar type axial flow pump leaves mobile and two kinds of structure can be adjusted. The use of large axial flow water pump load (key) refers to the total flow At run may have to make bigger changes, adjust leaf installation Angle can keep pump under different load running in high efficiency area. The leaves of small and medium-sized pump installation Angle is usually fixed.

( 1) The centrifugal water pump pump shell to install the pump manufacturer. For speakers is leaking, closed type centrifugal pump layer ( Do try) When installation should be basically ring ( Built-in parts) With centrifugal pump, axial flow pump manufacturer basically ring layer embedded parts in accordance with the relevant provisions basically is not leaking, the centrifugal water pump link between surface needs to be placed between the sealing gasket ( Circle) To prevent leaking water seepage centrifugal pump layer. ( 2) Pipe installation. Centrifugal pump selection of pipe installation lifting chain, lifting chain support for embedded at the bottom of the site casting pieces of thick steel plate. The hexagonal end of the anchor bolt installation, hex bolt and flange surface layer, placed special anchor bolt sealing washer, prevent water layer by the anchor bolt to the centrifugal water pump leaking. Motor support plate installation. Motor base is installed on its axis, elevation and smoothness control method are with centrifugal pumps basically ring installation. Sound card rack installation service but not more than 2 mm deviation, sound card frame arrange ushering oil bearing or the standard deviation of less than 0. 07 mm / 1500, elevation deviation value not to exceed the cathode is 3 mm. For three-phase electric motor column type motor, motor with centrifugal pump according to the drive gear coupling. Installing a drive gear, base level effect is pump drive gear smoothness, pump shaft and the axis of rotation needs to be installed on the same lead, the tolerance value less than 0. 02mm/m。 After installation of the motor, after the commissioning, barring degrees with a dial indicator ( Between 800 azimuth dial indicator) Inspection, need to meet: motor axis of upper and lower guide roller bearing in motor shaft and the connecting shaft device of relative degree of pendulum is: 0. 03mm/m; The centrifugal water pump shaft bearing in motor shaft relative degree of pendulum is: 0. 04mm/m。
