√ AYG series Chemical Inline Centrifugal Pump Characteristics of Structure Pumps of this series are single-stage single-suction redially split vertical pipeline centrifugal pumps. The pumpcasing is in redial split and the place between the pump casing and cover is sealed by a limited sealing gasket; the pump casings of an aperture over 80mm is in dual-volute design, for the purpose to reduce the waterpower caused radial force and the pump vibration; a connector for residual liquid drain-out is set on the pump casing. Both suck-in and drain-out flanges of the pump casing are available with connectors for measuring and seal flushing.
Both inlet and outlet flanges of this pump hold same pressure class and nominal diameter and the vertical axis is presented in a linear layout. The linking type of the inlet and outlet flanges and the executive standard can be varied in accordance with the required size and pressure class of users and either GB, DIN or ANSI can be chosen.
The pump cover features insulation and cooling function and can be used to transport the medium which has a special requirement on temperature. On the pump cover an exhaust cork is set, used to exhaust both pump and pipeline before the pump is started. The size of the sealing cavity meets with the need of the packing seal or various mechanical seals, both packing seal and mechanical seal cavities are interchangeable and equipped with a seal cooling and flushing system. The layout of the seal pipeline cycling system complies with API 682. AYG series Chemical Inline Centrifugal Pump uses a rolling bearing to bear the pump load, which includes the pump load, the rotor weight and the instantaneous load caused at the pump start. The bearing is set in the incorporated bearing frame and lubricated with grease.
The impeller of this series pump comes as a single-stage single-suction closed impeller and is mounted on the axis with one key and one impeller nut with a steel screwed sleeve, whose self-lock function makes the impeller safely and reliably mounted; all the impellers have been balancing processed and, when the specific value between the maximum outer diameter and the width of the impeller is less than 6, dynamic balance
is needed; the waterpower design of the impeller makes the cavitation property of the pump enhanced to the maximum.
The axial force of the pump is made balanced by means of the front and back wearable rings and balancing holes of the impeller and the pump can be kept at a higher waterpower efficiency by replacing either the pump s or the impeller's wearable ring. A lower NPSH value will leave a lower pump installation height and a reduced installation cost.
Viewing from the motor, the pump moves clockwise.
Drawing and Advantage
A bearing frame is set in between
its motor and pump, so it can be used in a place of a higher temperature or in an important case (see the sectional view).
Compared with the horizontal pump, the vertical pipeline pump of the same property features a less land area and a simpler pipeline link, saving the basis investment.
MODEL SLECTION
the approximate property range
of it can be decided by means of the model spectrum upon the corresponding speed and the final selection needs to think of the pump's NPSH value, efficiency and maximum allowed torque (power of the motor) and use the individual performance curve .
