Display of tooling and die for rotating cutter head of air tightness testing mixer

As an essential part of rotary blade, its air tightness is very important for the safe use of blender. If the air tightness of rotary blade is poor, it is easy to cause low efficiency of blender. Therefore, the air tightness test will be carried out when they leave the factory. Hermes technology has been doing a lot of research on the air tightness test of mixer parts. This time we will share the air tightness test of the rotary blade of the steam mixer, hoping to be helpful to you.

Air tightness detector of mixer rotating cutter head

1、 Appearance display of mixer rotary blade

1. The shape of the rotary cutter head of the mixer is special. The head is a bowl with hollowed out all around, the middle is a straight blade, and the middle of the cutter head is a long column, which has a high degree of precision.

2. The detection of the device needs to meet its shape and nondestructive, accurate and precise detection, so the detection conditions are relatively high. Because of its special shape, it can not be fixed in the detection, so it is difficult to detect its air tightness;

2、 Demonstration of air tightness testing process of mixer rotating cutter head

1. According to the shape of the rotary cutter head of the mixer, Harris has customized a special mold (as shown in the figure below). There is a special clamping position on the top and bottom of the mold to fix it, and a bowl shaped tool to hold the cutter head is on the top. Because the shape of the mold is fixed during the inspection, the mold on the tooling will close the bowl shaped tool of the cutter head, Forming a closed space;

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

3、 Parameters of air tightness detector for mixer rotating cutter head

1. High sensitivity pressure sensing and regulating unit, combined with advanced differential pressure software algorithm, the minimum resolution can reach 0.1pA, which has won the national patent.

2. The patented technology of "IVT pneumatic sealing valve island" independently developed by Harris 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 positive and negative pressure forms and eight test methods: two pressure forms and five test methods can be written into more than 20 test functions.

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

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

6. A variety of pressure regulating components and ranges are available. Wide range of air pressure (- 80kPa & amp; mdash; 1MPa) optional. Selecting electronic pressure regulating valve can realize multi group pressure sequence test.

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

8. Bar code scanning function and printer can be purchased to facilitate product data management and quality traceability. Up to 200000 historical records of the instrument 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 the way of volume.

10. Ultra high stability, and ease of use, after a rigorous test of the market.

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