As an indispensable part of the rotating cutter head, its air tightness is very important for the safe use of the mixer. If the air tightness of the cutter head is poor, the use efficiency of the mixer will be low.Therefore, air tightness will be tested before leaving the factory.Hairis Technology has always done a lot of research on the air tightness testing of mixer parts. This time we will use the air tightness testing of the rotary cutter head of the steam mixer to share it. We hope it can be helpful to you.

Air tightness tester for mixer rotating cutter head

1. Appearance display of the mixer rotary cutter head

1. The shape of the rotary cutter head of the mixer is relatively special. The head is in the shape of a hollow bowl with a straight blade in the middle. The middle of the cutter head is a long cylinder, which is highly precise.

2. The detection of this device needs to meet its appearance and non-destructive, accurate and precise detection, so the conditions for detection are relatively high.Due to its special shape, it cannot be fixed during inspection, so it is more difficult to inspect its air tightness;

2. Demonstration of the air tightness testing process of the mixer rotary cutter head

1. In view of the shape of the rotating cutter head of the mixer, Haireisi customized a special mold for it (as shown below). The upper and lower parts of the mold have special clamping positions to fix it, and the upper part is a bowl-shaped device specially designed to hold the cutter head. When the tool is inspected, the shape of the mold is in a fixed state. During the inspection, when the tool is put on the mold, the bowl-shaped device of the cutter head will be closed to form a closed space;

2. After placing the mixer rotary cutter head into the tooling mold, we need to set the program first, and then press the start button after the connection is made.At this time, the upper and lower molds begin to close, and the instrument will fill clean gas without impurities into the inside of the mixer's rotating cutter head through the upper mold. The instrument display will judge the degree of air tightness based on the gas saturation inside the mixer's cutter head.

3. Air tightness detector parameters of the mixer rotary cutter head

1. High-sensitivity pressure sensing and adjustment unit, combined with advanced differential pressure software algorithm, the minimum resolution can reach 0.1Pa. This algorithm has obtained a national patent.

2. The patented technology independently developed by Hairuisi, "IVT pneumatic sealing valve island", greatly improves the test accuracy, ensures the stability of the instrument, and greatly improves the inflation speed.

3. Multiple test functions: The instrument integrates two pressure forms, positive and negative, and 8 test methods: two pressure forms and five test methods can be programmed into more than 20 test functions.

4. It has more than 200 groups of subroutines. Each group of subroutines can be programmed independently, single selected and combined to meet various complex testing requirements.

5. Full-touch large-screen intelligent operating system, graphical UI design based on the detection process, the operation interface is simple and clear, easy to teach and learn.

6. A variety of pressure adjustment components and ranges are optional, with a wide air pressure range (-80KPA&-1MPa) optional.The optional electronic pressure regulating valve can realize multiple sets of pressure sequential tests.

7. Multiple communication interfaces: built-in RS232 serial port, RJ45 network port, USB communication interface, LTP external I/O control port, supporting multiple communication protocols.

8. Optional barcode scanning function and printer are available to facilitate product data management and quality traceability. The instrument history record can reach up to 200,000 items and can be exported to the computer in batches.

9. The standard volume identification function can automatically identify the volume of the sample to be tested, and measure and judge the leakage rate in a volumetric manner.

10. Ultra-high stability and ease of use have passed the rigorous test of the market.

11. A variety of accessories are available, including inflatable bypass, quick connector, and standard leak hole. At the same time, the instrument supports third-party calibration and can issue a calibration report.
