Submersible pump testing device and submersible pump testing method

Abstract

The invention discloses a submersible pump testing device and a submersible pump testing method, and belongs to the technical field of water pump detection. The submersible pump testing device comprises an overflow pool, a lifting platform and a testing device for detecting the performance of a water pump, the testing device comprises a flow testing unit, a pressure testing unit, an electronic megger, an electrical performance testing unit, a noise testing unit and a vibration testing unit. The submersible pump testing method comprises the following steps: controlling a lifting platform to move to a target depth position in a first pool of an overflow pool; starting the water delivery pump and the test pump, and acquiring water pump performance data by the test device; and comparing the performance data with a standard parameter range, and if the performance data is not within the standard parameter range, judging that the submersible pump has a problem. According to the invention, the environment during the river test is simulated comprehensively, and the fault of the water pump can be found or the fault generated during the river test can be reproduced comprehensively and accurately.

Description

technical field

[0001] The invention belongs to the field of water pump testing, in particular to a submersible pump testing device and a submersible pump testing method. Background technique

[0002] The physical model test of river engineering is an important means to predict the movement of water and sediment and the evolution of the river bed. Using the knowledge of fluid dynamics, the prototype landform is scaled into a model according to a certain scale, and the influence of the flow field change on the terrain or structures is simulated in the model to reverse the inference. Or predict the impact of prototype flow field changes on terrain or structures. The water flow needs to be simulated in the model, and the water flow power is generally provided by a submersible pump. The most commonly used one is the QS500 series submersible pump produced by Taifeng Water Pump Factory, which has a suitable volume and a moderate flow rate. The overall river engineering model is ba...
