20 hp Horizontal Centrifugal Pump

20 hp horizontal centrifugal pump with 32.5m³/h maximum flow, 82m maximum head, and 65mm diameter of inlet and outlet.

Features:

1. The centrifugal pump has a horizontal structure. The diameter of the inlet and outlet are the same. If a protective cover is added, it can be used in the open air.
2. It is easy to install and maintain. There is no need to dismantle the pipeline system, just lift off the conjunction flat nut of the vertical pump. Then, all the rotor parts can be taken out.
3. A horizontal centrifugal pump can operate in series and parallel connection according to the requirements of flow and head.
4. The installation angle of the pump outlet can be 0°, 90°, or 180° to meet different connection occasions.

Specifications:

Horizontal centrifugal pump dimension (unit: mm):

Tips: Centrifugal pump troubleshooting - serious vibration of pump and abnormal noise

1. If the centrifugal pump foundation is stale
   When vibration occurs, please first check if the anchor bolts of the centrifugal pump are tight. If they are not tightened, it will cause the centrifugal pump to vibrate. Please also consider whether the foundation strength of the foot is sufficient. Sometimes, due to design reasons, the soft foundation can also cause vibration.
2. Coupling alignment
   Many centrifugal pumps are driven by couplings, and there are many types of couplings. The alignment of the normal three-paw coupling directly affects the normal operation and service life of the coupling, shaft, bearing, and machine seal.
3. Alignment
   Improper alignment is also a common reason causing vibration. The alignment should be regulated in the specified range according to the standard strictly.
4. Bearing inspection
   Check if the bearing is correctly installed or damaged.
5. Adjustment of the rotor central position
   The water pump rotor must be concentric with the stator, otherwise, friction will be generated in the water pump operation, thus causing variation.
6. Shaft curving and rotor measurement
   If the cause of the variation can not be found externally, the pump can only be disassembled. Please firstly measure and correct the bending of the shaft. After confirming that there is no problem, the rotor will be mounted, and the overall sway and scoring will be measured. If it exceeds the standard, it must be corrected.
7. Inspection of the dynamic and static balance
   After the centrifugal pump is disassembled, to avoid vibration when the pump is turned on, the impeller should also be conducted with the static balance test.
8. Influence of external conditions on the water pump
   When all the problems of the pump itself are eliminated, if the vibration problem still cannot be solved, the influence of external conditions on the pump should also be considered. For example, the resonance caused by the natural frequency of the pump base is similar to the vibration frequency, the vibration of the pump caused by the failure of the prime motor, and the strong counterpart used for the connection between the pipeline and the pump will also probably cause abnormal vibration of the pump.
