- 8 to 10 people maximum per session.
Contents :
09:00 - 10:30
OPERATION
- Characteristic curves and performance of a centrifugal pump: flow, power and efficiency
- Operating limits: cavitation, zero flow
10:30 - 10:45
Break
10:45 - 12:15
OPERATION
- Starting a centrifugal pump
- Principles of flow control :
o System pressure drop
o Flow control: control valve, by-pass, variable speed
- Operating point and operating limits:
o Minimum flow, cavitation, vibration.
o Best efficiency point versus flow
- Operation of 2 pumps in parallel and in series:
o Advantages, disadvantages
o Performance curves
12:15 - 13:15
Lunch
13:15 - 15:15
TROUBLESHOOTING
- On-site performance checks: hydraulic and electrical balances.
- Causes of efficiency losses :
o Abnormal load losses :
Suction filter clogging
Suction pressure drop
Foreign bodies
o Abrasion, erosion, cavitation, wear and tear
- Behavioral anomalies :
o Abnormal vibration
o Abnormal heating of bearings
o Sealing leaks
o Pump bypass: role of the non-return valve
- Excessive energy consumption: causes and remedies
15:15 - 15:45
Break
15:45 - 17:00
INSTALLATION
General principles of pump assembly
- Common base: pump, coupling / drive machine.
- Pipe coupling: principle and tolerances.
- Bends and flow stabilizers.
- Position of suction pipes.
Implementation / working method :
Interactive, one-day, face-to-face course. Powerpoint support will be shared at the beginning of the course in paper and digital formats.
A questionnaire will be sent to trainees prior to the course in order to adapt the course content to participants' expectations as far as possible.
A course evaluation questionnaire will be distributed to participants at the end of the course.
