This way of immersing the measured object in water one by one and observing the formation of bubbles usually takes a long time and has high labor intensity, and the detection efficiency is low.

[0031] In addition, if the terms "first", "second" appear, these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implying the number of technical features indicated. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise specifically limited.

[0034] It should be noted that if an element is referred to as "fixed to" or "provided on" another element, it can be directly on another element or there can be a middle element. If an element is considered to be "connected" to another element, it can be directly connected to another element or there can be a middle element. If present, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in the present application are only for illustrative purposes and do not represent the only implementation.
[0035] The submersible pump is usually in a liquid environment during operation, and the sealing test can ensure that the seal of the pump does not leak under liquid pressure, thereby ensuring the normal operation of the pump. In addition, the medium transported by the submersible pump can be corrosive or otherwise dangerous, and the sealing insulation test can detect the integrity and reliability of the seal to prevent leakage of the medium and avoid damage to the environment and equipment. Therefore, the sealing insulation test is an important part of the maintenance and management of the submersible pump, and is of great significance to the normal operation and safety of the equipment.
[0036] At present, when the sealing insulation test of the submersible pump is carried out, the submersible pump is usually completely immersed in the sealing test water tank, the outer discharge port is connected to compressed air, the pressure reaches 0.6MPa, and the pressure is maintained for 5 minutes to check whether there is any bubble overflow at any position. At the same time, pressure test is carried out by filling water or air into the pump and gradually increasing the pressure to check whether there is leakage or weakness at the sealing position. However, this method mainly relies on visual observation of the formation of bubbles to judge the leakage, so the detection accuracy is greatly affected by human factors, and for small leaks, the bubbles may be very small and difficult to detect, which may lead to missed detection or misjudgment. In addition, the observation of bubbles is easily affected by factors such as light and observer experience, and different operators may draw different conclusions. In addition, due to the problems of bearing capacity and easy observation of bubbles, the existing test device can only accommodate one submersible pump for detection at a time. This way of immersing the measured object in water one by one and observing the formation of bubbles usually takes a long time and has high labor intensity, and the detection efficiency is low, which cannot meet the rapid and efficient detection demand on large-scale production lines.
[0037] Therefore, the application provides a sealed insulation testing device, which can simultaneously perform soaking and detection operations on multiple pump bodies, improves detection efficiency while ensuring detection effect.
[0038] Referring to Figure 1 An embodiment of the application provides a sealed insulation testing device, which comprises a testing container 1 and a partition 2. The testing container 1 is used to contain detection liquid and pump bodies to be detected, so that the pump bodies can be soaked in the detection liquid for detection. The partition 2 is used to separate a containing cavity 3 in the testing container 1, so that multiple pump bodies soaked simultaneously are not easily interfered with each other.
[0039] Specifically, the testing container 1 is internally provided with the containing cavity 3, which is used to contain the detection liquid and the pump bodies to be detected. The testing container 1 is a steel container, which has high bearing capacity, so as to simultaneously contain multiple pump bodies to be detected.
[0040] Referring to Figure 1 and Figure 2 The partition 2 is arranged in the testing container 1 and separates the containing cavity 3 into a first chamber 31 and a second chamber 32, so as to facilitate an operator to place multiple pump bodies while preventing the multiple pump bodies from interfering with each other after being placed. The first chamber 31 and the second chamber 32 are communicated, so as to ensure that the detection liquid in the first chamber 31 and the second chamber 32 has the same temperature, pressure, chemical composition and other states, thereby providing the same testing environment for each pump body. The consistent testing conditions help to improve the accuracy and repeatability of the detection results, and ensure that the performance test results of each pump body are comparable. The testing of multiple pump bodies in the same testing container 1 improves the testing efficiency and reduces the testing cost.
[0041] It can be understood that the testing container 1 and the partition 2 of the application are combined through physical isolation and environmental communication, which effectively solves the interference problem of multiple pump bodies during simultaneous testing, ensures the consistency of the testing conditions, and improves the detection effect and efficiency.
[0042] In summary, the sealed insulation testing device can first inject the detection liquid into the containing cavity 3 of the testing container 1, and then place the pump bodies to be detected in the first chamber 31 and the second chamber 32, and immerse the pump bodies in the detection liquid for detection. One or more pump bodies can be placed in the first chamber 31 and the second chamber 32. The sealed insulation testing device is made of steel, which ensures that the testing container 1 for containing the detection liquid and the pump body has high bearing capacity, so that the testing container 1 can contain multiple pump bodies to be detected at the same time, and the multiple pump bodies can be soaked and detected at the same time, improving the detection efficiency. The containing cavity 3 in the testing container 1 is separated by the partition 2, so that the multiple pump bodies soaked at the same time are not easy to interfere with each other. The first chamber 31 and the second chamber 32 separated by the partition 2 are communicated, which ensures that the detection liquids in the first chamber 31 and the second chamber 32 are consistent, thereby ensuring the consistency of the test conditions and the detection effect.
[0043] In one embodiment, the sealed insulation testing device further comprises a resistance detector for connecting the pump body in the containing cavity 3 to detect the sealed insulation of the pump body. The resistance detector can be provided on the testing container 1 for use at any time. It can also be placed separately to reduce the probability of damage. By using the resistance detector to detect the sealed insulation of the pump body, the problems of limited detection accuracy, strong subjectivity, time-consuming and low efficiency of the method of relying on naked eye observation of the formation of bubbles to judge leakage can be avoided, and the detection effect is guaranteed.
[0044] Specifically, in the embodiment of the application, the resistance detector is a multimeter. The multimeter probes are connected to different winding connection ends of the pump motor to measure the insulation resistance between the windings. Under normal circumstances, the resistance value should be between tens of ohms and thousands of ohms. If the resistance value is too low or zero, it may indicate that there is a short circuit between the windings, and the pump body has a sealed insulation problem.
[0045] Referring to Figure 1 and Figure 2 In one embodiment, the volume of the first chamber 31 and the volume of the second chamber 32 are consistent, which can effectively eliminate the factors of inconsistent test conditions caused by volume difference, thereby improving the accuracy and repeatability of the test results and ensuring the reliability of the detection effect.
[0046] It can be understood that when the volumes of the two chambers are the same, the same volume of detection liquid is injected, which can make the liquid in the two chambers more evenly distributed. In this way, the liquid height, pressure and flow state and other conditions in each chamber are more similar, thereby providing similar test environment for the pump body immersed therein. In addition, the heat capacity of the liquid is related to the volume, and the same volume means that the heat capacity of the liquid is similar, and the temperature change of the liquid in the two chambers will be more synchronized, avoiding the deviation of the test results caused by the temperature difference. And if the detection liquid contains specific chemical components, the consistent volume can ensure that the concentrations of these chemical components in the two chambers are more consistent.
[0047] Referring to Figures 1-3 , specifically, the test container 1 includes a bottom plate 11, two first side plates 12 and two second side plates 13, the two first side plates 12 and the two second side plates 13 are arranged on the same side of the bottom plate 11, and the first side plate 12 and the second side plate 13 are connected vertically, the two first side plates 12 are arranged in parallel and opposite to each other, and the two second side plates 13 are arranged in parallel and opposite to each other. The partition 2 is a partition plate, the two ends of the partition plate are connected with the two first side plates 12 respectively, and the distance between the partition plate and the two second side plates 13 is consistent. The partition plate has a gap with the bottom plate 11, so that the first chamber 31 and the second chamber 32 separated by the partition plate are communicated.
[0048] In one of the embodiments, the material of the test container 1 is 316L stainless steel. Among them, 316L is a kind of ultra-low carbon austenitic stainless steel, and the carbon content is at most 0.03%. This low carbon content helps to reduce the precipitation of carbides in the welding process, thereby improving the corrosion resistance of the welded part. It can be understood that the corrosion resistance of ordinary steel is relatively poor, and it is easy to rust in humid or corrosive environment. The detection liquid used in the sealing and insulation test is mostly salt water, which will cause corrosion to the test container 1. Therefore, the application utilizes the significant advantages of 316L material steel in corrosion resistance and welding performance, so that the test container 1 can be suitable for harsh chemical environment.
[0049] In one of the embodiments, the material of the partition 2 is consistent with the material of the test container 1, so as to carry out the welding operation. That is, the material of the partition 2 is 316L stainless steel. Due to the low carbon content of 316L, it can maintain excellent corrosion resistance after welding without subsequent heat treatment, and the welding performance is superior.
[0050] Referring to Figure 1 and Figure 4 , in one of the embodiments, the sealing and insulation test device further comprises a drain faucet, which is arranged on the test container 1 and communicates with the containing cavity 3, so as to discharge the detection liquid in the test container 1 after the detection is completed. Specifically, the test container 1 is provided with a drain port communicating with the containing cavity 3, and the drain faucet is arranged on the drain port.
[0051] In one of the embodiments, the sealed insulation testing device further comprises a roller assembly 5 arranged on the testing container 1 to assist the movement of the testing container 1. Specifically, the roller assembly 5 comprises four moving wheels arranged on the four corners of the bottom plate 11 of the testing container 1 to realize the transfer of the testing container 1, thereby improving the convenience of the transfer of the testing container 1.
[0052] In one of the embodiments, the testing container 1 is provided with reinforcing members 6 arranged on the side of the testing container 1 to reduce the bottom stress and improve the load. Specifically, the reinforcing members 6 are a plurality of reinforcing ribs arranged on the two second side plates 13 of the testing container 1. It can be understood that the partition plate is connected with the two first side plates 12, and thus the load at the two first side plates 12 has been improved. Therefore, the reinforcing members 6 only need to be arranged on the two second side plates 13 to improve the load at the two second side plates 13, thereby saving the cost.
[0053] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.
[0054] The above embodiments only express several implementation manners of the present application, and the description is specific and detailed, but it should not be understood as the limitation of the patent application scope. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
