Shenyang Pump Manufacturing Co., Ltd. develops various computer (water) pump test benches/performance test benches for professional pump units, pump users, and pump testing units, or refurbishes various unqualified pump test benches.

The development of the test bench fully complies with the corresponding international and national standards, and the system accuracy can reach the highest accuracy of the corresponding standards. The standard that meets is: ISO9906:2000 rotor power pump. Hydraulic performance acceptance test. First and second grade; GB/T 3216-2005 “Hydraulic Performance Acceptance Test for Rotating Power Pump”, GB/T 12785-2002 “Test Methods for Submersible Electric Pump”, GB/T 9064-88 “Test Methods for Screw Pump”, GB6245-2006 “Fire Pump”, GB/T 3216-89 “Test Methods for Centrifugal Pump, Mixed Flow Pump, Axial Flow Pump, and Vortex Pump”, JB/T 8092-2006 “Small Submersible Electric Pump”, JB 5118-2001 “Wastewater Submersible Electric Pump”, JB/T10601-2006 “Vortex Self suction Electric Pump”, and JB 8091-98 “Test Methods for Screw Pump”.

The developed test bench can test various types of pumps, including boiler feedwater pumps, centrifugal pumps, submersible pumps, mixed flow pumps, axial flow pumps, vortex pumps, submersible pumps, screw pumps, etc.

The developed test bench can test pump drive mechanisms, including single-phase AC motors, three-phase AC motors, DC motors, high-voltage motors, AC asynchronous motors, AC synchronous motors, 50Hz/60Hz AC motors (can use 40-65Hz), internal combustion engines, magnetic turbines, wind turbines, and solar motors.

Test scope: Motors of any power and pumps of any diameter. It can perform high-precision testing, from several watts of water pumps used in aquariums to thousands of kilowatts of water pumps used in power plants.

Test items: pump performance test, cavitation test, noise and vibration test, leakage test, bearing temperature rise test, operation test, as well as motor no-load test, load test, temperature rise test, and locked rotor test.

Measurement parameters: three-phase AC voltage, current, power, grid frequency, speed, pump inlet pressure, outlet pressure, flow rate, motor winding resistance, temperature, vibration, noise, torque (when using torque method), shaft power (when using torque method), etc.

Test medium: various liquids: clean water, seawater, lubricating oil, gasoline, diesel, heavy oil.

Software environment: Chinese and English interface, C++development, running Windows 98/ME/2000/XP, querying all tested pumps in the database, querying, generating curves, and printing at any time. The printing format can be freely formatted using Word. The pump station/pump unit testing management software is written using LabView, with a luxurious interface.

Pump performance and cavitation tests can calculate parameters such as head, flow rate, pump efficiency, unit efficiency, shaft power, and cavitation margin; Analyze indicators such as flow rate at rated head, head at rated flow rate, performance measurement intersection point, measurement flow deviation, measurement head deviation, and measurement pump efficiency deviation; Draw the head flow rate (H-Q) curve and efficiency flow rate（ η- Q) Curve, power flow rate (P-Q) curve, head NPSH (H-NPSH) curve, etc.
