Description

technical field [0001] The invention relates to a testing method and device for a motor of a submersible pump with a self-filling and pressurizing system, belonging to the technical field of submersible pumps. Background technique [0002] The submersible pump is an important equipment used to transmit the water source of the water source to a longer distance or to a higher position. It is widely used in many life and production fields such as groundwater mining, mine operations, and landscape fountains. Because the submersible pump During operation, it needs to be soaked in water for a long time, and there are often a large amount of minerals dissolved and a large number of hard particles suspended in natural water bodies, especially in the chemical industry, etc. This phenomenon is more prominent, so the water body often presents Different acidity, alkalinity and sediment content.

[0002] The submersible pump is an important equipment used to transmit the water source of the water source to a longer distance or to a higher position. It is widely used in many life and production fields such as groundwater mining, mine operations, and landscape fountains. Because the submersible pump During operation, it needs to be soaked in water for a long time, and there are often a large amount of minerals dissolved and a large number of hard particles suspended in natural water bodies, especially in the chemical industry, etc. This phenomenon is more prominent, so the water body often presents Different acidity, alkalinity and sediment content. At the same time, submersible pumps often need to be located in deep underground water layers, so submersible pumps need to bear a certain pressure during operation. Combining these factors, it is easy to cause the motor shell of the submersible pump to be damaged during use. The body, seals and insulation properties are damaged due to corrosion. At the same time, the submersible pump and motor casing, connecting shaft and submersible pump blades are damaged due to solid particles in the water, which seriously affects the stability of the submersible pump. And service life, and currently in view of this problem, in the actual production and use of submersible pumps, there is a lack of an effective testing equipment and testing method for the operation status of submersible pumps and the resistance of submersible pump motors to water erosion, and It is only through simple data accumulation and inference after long-term use of the submersible pump, which on the one hand causes inaccurate test data of the submersible pump, and on the other hand causes serious loss of the submersible pump and a large waste of electric energy and water resources At the same time, it is extremely difficult to operate and implement. At the same time, due to the great variability and flexibility of natural water bodies, the accuracy of traditional data accumulation and inference to obtain detection data cannot effectively meet the requirements of submersible pump testing. For this At present, there is an urgent need to develop a professional testing equipment and testing method that can efficiently simulate the operation of submersible pumps in a natural environment, which can meet the requirements of improving the test accuracy of submersible pumps and simplifying the test operation of submersible pumps
