The invention relates to a water pump test method, aiming at providing a water pump type test method. The method comprises: inputting basic data and test parameters of a water pump to be tested into a PLC control system; determining whether the system is normal and whether each parameter satisfies a starting condition by the PLC control system automatically; equally dividing test flow points according to the minimum flow point, the maximum flow point and test points number of the water pump to be tested; adjusting a fluid control valve of water pump outlet; adjusting flow to a designated flow point; recording parameters of each flow point; calculating to obtain pump lift, motor input power, effective power of the pump and shaft power parameter of the pump; and generating a performance curve of the performance test. According to the invention, various performance tests of the water pump type test are automatically completed independent of manual intervention, with the method, test time can be greatly shortened. The method has the advantages of high accuracy test device, accurate and reliable result, visual process and rapid response to abnormal cases.
Description
Technical field [0001] The invention relates to a water pump type inspection method, to be precise, to a remotely operated automatic control water pump type inspection method. Background technique [0002] With the rapid development of science and technology, water pumps can no longer be regarded as high-tech products. However, water pumps have always played a very important role in the development of the national economy. They are only used in energy, petrochemical, aviation, and There are a large number of applications in important fields such as aerospace, steel, and military industry. [0003] The performance parameters of water pumps are related to the safe operation of the process. Some water pumps used in key processes must be tested before leaving the factory. A set of high-precision and easy-to-operate fully automatic test system can not only improve the detection efficiency of the pump factory, but also avoid errors caused by manual operation. It is an important sign of ...
