Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic suspension, and in particular relates to a flow characteristic detection device for a high-purity magnetic suspension pump. Background Art

[0002] High-purity magnetic levitation pump is an advanced pump technology that uses magnetic levitation technology to achieve contactless bearings, avoiding the friction and wear of traditional mechanical bearings and improving the reliability and efficiency of the pump. In order to study the flow characteristics of high-purity magnetic levitation pumps, corresponding flow characteristic test devices are usually designed to obtain performance data of the pump under different working conditions.

[0003] The existing flow monitoring device has a complex structure and a long transmission chain, which is easy to cause cumulative errors. During assembly or maintenance, the process is cumbersome, and there are many weak parts. In actual engineering applications, it is costly and laborious, and very inconvenient. Therefore, a solution is needed to solve the above problems.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to provide a high-purity magnetic levitation pump flow characteristic detection device which changes the flow characteristics by spiral blades so that the infrared counter can convey the flow characteristics of the flowing liquid to the outside world according to the rotation characteristics of the spiral blades.

[0006] To achieve the above-mentioned purpose, the utility model proposes a high-purity magnetic levitation pump flow characteristic detection device, which is characterized in that it includes a threaded connecting pipe, and an input end fixing plate and an output end fixing plate arranged outside the two ends of the threaded connecting pipe, the input end nut is threadedly connected to the input end fixing plate, the output end nut is threadedly connected to the output end fixing plate, an infrared counter is threadedly connected inside the output end nut, and a spiral blade is arranged in the cavity of the threaded connecting pipe along the extension direction of the threaded connecting pipe.

[0007] In one example, the input end and the output end of the threaded connection pipe are respectively provided with a first elastic washer and a second elastic washer.

[0008] In one example, a filter element is disposed in the threaded connection pipe, and the filter element is located at one end of the input end nut.

[0009] In one example, a support rod is provided between the input-end fixing plate and the output-end fixing plate, and the support rod is connected to the input-end fixing plate and the output-end fixing plate by bolts.

[0010] In one example, the threaded connecting tube is made of transparent material.

[0011] In one example, the support rod is sleeved on the threaded connection pipe.

[0012] The high-purity magnetic levitation pump flow characteristic detection device proposed by the utility model can bring the following beneficial effects: through the bolt connection between the input end fixing plate, the output end fixing plate and the support rod, a barrier can be formed between the detection device and the outside world, reducing the possibility of collision with the threaded connecting pipe during use and improving the service life. At the same time, a filter element is arranged in the input end nut, which can filter foreign particles and prevent them from entering the cavity of the threaded connecting pipe and colliding with the spiral blades, thereby improving the safety of the spiral blades. Elastic gaskets are arranged inside the input end fixing plate and the output end fixing plate, which improves the sealing of the flow detection device. Through the built-in infrared counter in the output end nut, when the spiral blade rotates, a signal can be sent to the outside world, thereby calculating the flow characteristic of the flow monitoring device.

[0028] Working principle: The spiral blades set in the threaded transparent connecting tube can transform the flow characteristics of the flowing liquid into the rotation characteristics of the spiral blades, so that the infrared counter in the output end nut can convey the flow characteristics of the flowing liquid to the outside staff according to the rotation characteristics of the spiral blades, so as to obtain the performance data of the pump under different working conditions.
