The main purpose of speed testing is to conduct tests on pump characteristics, pump cavitation, and series/parallel connections of pumps. Product Features:
1. The piping system is made of ABS pipes
2. Centrifugal water pump adopts low-noise, rust free and environmentally friendly type
3. The basic performance parameters of the water pump are measured using an imported differential pressure sensor, and the water temperature is measured by an imported digital temperature sensor (DS18B20)
4. Digital orifice flowmeter for measuring water flow rate of water pump
5. Variable frequency drive controls the speed of the water pump
Precautions for heart pump performance testing experiment:
Preparation before the experiment:
Pump exhaust: Before starting, it is necessary to fill the pump with liquid and exhaust the air, otherwise the pump cannot deliver normally and the data will be distorted.
Check the equipment: Confirm that the power supply is not missing phase, the direction is correct, and avoid burning or damaging the pump; The pressure sensor should be installed in the straight pipe section, away from interference sources such as bends.
Valve operation: The valve should be opened and closed slowly to prevent damage to the instrument due to sudden pressure changes.
Experimental process:
Stable reading: Record data after the flow rate is stable to avoid fluctuations affecting the results.
Parameter control: Maintain a constant liquid temperature, as temperature changes can affect viscosity, which in turn affects head and efficiency.
Safe operation: Do not touch the spindle during operation, high-speed rotation is dangerous.
Post experimental processing:
Data recording: Complete recording of parameters such as flow rate, pressure, power, etc., to facilitate subsequent analysis.
Equipment maintenance: Drain the water from the device to prevent rust or frost cracking.
