Abstract

The present invention relates to a hardware system of a high-pressure pump performance test bench using PXI bus technology, including a control host based on the PXI bus structure, two NIPXI-6238M series data acquisition cards and a NIPXI-6514 industrial-grade IO card; The control host based on the PXI bus structure uses the AI ​​channel of the data acquisition card to collect the pressure, temperature, torque, and speed signals of the pump under test, and uses the CTR counter to collect the flow pulse signal of the pump under test. The channel controls the proportional relief valve, frequency converter, and electric control valve in the hydraulic system; the industrial-grade IO card is used to collect the motor running status of the pump under test, the filter is blocked, and the oil tank liquid level switch signal is collected and output at the same time. The switch signal controls various valves and motors. The invention has simple hardware structure and reasonable design, and can efficiently and accurately complete the performance test of the high-pressure pump.

Description

technical field [0001] The invention relates to the technical field of high-pressure pump performance testing, in particular to a hardware system of a high-pressure pump performance testing platform using PXI bus technology. Background technique [0002] As the power component of the hydraulic system, the hydraulic pump has a very important position. Its performance has a huge impact on the performance of the entire hydraulic system. Whether the hydraulic pump can work normally and stably is related to whether the whole system can meet the design and operation requirements. Therefore, it is of great significance to accurately test the performance of hydraulic pumps. At present, hydraulic transmission systems are developing towards high pressure, high speed, large flow and high power. Therefore, it is necessary to develop high-power pumps with certain test accuracy and automation. High pressure pump performance test bench is particularly important. [0003] With the continuo...
