High-performance test system for pump

Abstract

The invention discloses a high-performance test system for a pump. The system comprises an incoming power supply cabinet, a frequency conversion system, an outgoing power distribution system and a test console. The outgoing line power distribution system is connected with a motor; the motor is connected with a pump; the inlet wire power supply cabinet is connected with the frequency conversion system through a cable. The frequency conversion system is connected with the outgoing line power distribution system through a cable, the incoming line power supply cabinet, the frequency conversion system, the outgoing line power distribution system, the motor and the pump are connected with the test console through cables and communication lines, and the test console is used for detecting signalsof the incoming line power supply cabinet, the frequency conversion system, the outgoing line power distribution system, the motor and the pump and feeding back the signals. The invention provides a high-performance test system for a pump, which not only can complete a conventional function test and a performance test of the pump according to the requirements of a pump test working condition, butalso can meet the test requirements of a pump with a wide capacity range and multiple voltage classes, and is low in cost and small in space occupation ratio.

Description

technical field [0001] The invention relates to the technical field of industrial pump testing, in particular to a high-performance testing system for pumps. Background technique [0002] With the acceleration of the development of water treatment, petrochemical, electric power, oil and gas, agriculture and other industries, as well as the construction of projects, the demand for pumps continues to expand, and pump factories build more and more pump test stations in order to improve the function and performance of pumps , Frequency conversion technology and industrial automation are the trend and trend of the current industrial control technology development. It can greatly improve the control performance, service life and personnel safety of the test site of the pump. Therefore, a large number of variable frequency power supply and remote control are used in the construction of the pump test station. The test bench is used to complete the test of the whole bench.

AI Technical Summary

Problems solved by technology

Although these two frequency converter methods are feasible, they both have disadvantages. The first method requires multiple frequency converters to meet the demand, which occupies a large area and requires a large investment in equipment. Although the second method only has one frequency converter According to the highest voltage and current selection, the capacity of a single unit is large. When the capacity exceeds a certain limit, a high-power water-cooled inverter is required, and the investment in equipment is also high, and the size is large.
