IH Type Single Stage Centrifugal Chemical Pump
IH model chemical pump is single-stage end-suction (axial suction)
cantilever type centrifugal pump, which is used to transport
corrosive liquid with viscosity similar to water and without solid
particles. The marked and rated performances and dimensions adopt
ISO2858 international standard. It has such characteristics as wide
range of performance, high efficiency, high mechanical, chemical
and physical level and convenient maintenance etc. It is energy
saving type product recommended by the nation with its efficiency
being 5% greater than that of F model pump.
Structure Description
1. IH model pumps are the series of products designed according to
ISO international standards in all industries in China. It is
mainly composed of pump body, impellers, seal rings, impeller nuts,
pump cover, seal parts, intermediate support, spindle, suspended
parts and so on. 2. Structural features: the pump cover is fixed on
the intermediate support, and the pump cover is clamped in the
middle by coupling between pump body and intermediate support. On
the pump body, water is input axially and output radially. Support
feet can be fixed on the base directly. The suspended parts are
fixed onto the intermediate support through the rabbet, and are
supported onto the base by suspended frame. To make it convenient
to disassemble, the prolonged coupling is designed, so that it is
unnecessary to disassemble the coupled input & output pipes
during check and maintenance. To pump body and motor, only by
disassembling theintermediate coupler of the prolonged coupling,
users are able to screw out rotor part for check and maintenance,
which is a conventional structural pattern in the world. 3.
Rotation direction: the pump is driven by motor directly through a
prolonged coupling, seen from the side of the motor, it rotates
clockwise. 4. Spindle seal patterns: spindle seal patterns of pump
are of two types such as stuffing seal and mechanical seal. The
stuffing seal is that on stuffing case in pump cover, with software
stuffing for sealing, input water of a certain pressure into the
stuffing case, for cooling, lubrication and cleaning on seal;
mechanical seal is of two types such as single-surface mechanical
seal and double-surface mechanical seal, input water of a certain
pressure into the seal chamber, for washing and cooling on the
abrased surfaces.
