PUMPING SYSTEMS ASSESSMENT

Low effcient pump system evidences. Why pump has low effficiency.

Pumping system assessment. Pump system assessment steps.

Collection of information about a pumping system. Information about pump electric motor, hydraulic system

Measuring pump parameters at the site. Field test of the pump. Pump pressure measurment. Pump flow measurment. Pump power mwasurment.

Pump with bigger parameters than necessary. Pump is oversized.

Analysis of measured parameters Analysis of information about pump and system.

Shutoff test of a pump. Shut off test is used to define the real pump curve, the diameter of an impeller, the direction of rotation.

ASME ISO (14414) Pumping system energy assessment standard

1. Evaluation of the efficiency of a pumping system.

- Technical condition of installed pumps. The degree of wear and tear of installed pumps,

- Operating modes.

- Control methods and algorithms.

- Evaluation of the level of maintenance and control of parameters.

2. Developing methods of increasing pumping system efficiency.

- pump and electric motors replacement

- application of pumps control - speed control, parallel installation, a combined method of control

- upgrading of pumps (trimming of impellers, installation of new impellers

- replacing of the throttle or bypass controls

- developing control algorithms.

3. Conditions of implementation

- the acceptable cost

- the acceptable payback time
