The mixer also needs to do the seal test, you can use the hermetic tester to do the seal test

Blender is a kind of blender which can realize the mixing of a variety of fruits and vegetables. Under the action of water flow, the food is broken repeatedly. It is inevitable to produce water splashing everywhere, so a good mixer, its sealing requirements are particularly important, so we need to do a sealing test, to do a good sealing test can be usedAir tightness testing equipment.

The company has many years of experience in sealing inspection. For more than ten years, it has been committed to the waterproof inspection of various products and the R & D and production of sealing inspection equipment. We have rich experience in the sealing test of mixer, which overcomes the sealing test requirements when the mixer is rotating. We can use the sealing test to test the static sealing requirements of mixer, so as to determine the dynamic sealing degree of mixer according to the test data.

1、 Sealing test principle of mixer

The compressed air with a certain pressure and a certain volume is used to inflate the product. If the product has air filling holes, the air is directly supplied to the air filling holes. After a certain period of time, the air supply source is cut off, and the pressure sensor inside the instrument is used to monitor the pressure change of the product after inflation; If there is no air hole in the product, the mold is designed to package the product, and then the product surface is inflated quantitatively through the mold, the air source is cut off, and the pressure sensor of the internal instrument department is used to monitor the pressure change of the product after inflation

The parameters of Harris seal detector are as follows:

Air supply pressure: 0.4 ~ 1.2MPa

Power supply voltage: 220 V / 50 Hz or 110 V / 60 Hz

Pressure regulation range: - 40 ~ - 0.5kpa, 5 ~ 150kPa

Pressure regulation accuracy: 0.1kpa

Pressure test range: - 80 ~ 150kPa

The minimum resolution of pressure attenuation test is 1pA

Minimum resolution of leakage flow test: 0.01ml/min

This kind of sealing test equipment is not only suitable for the sealing test of mixer, but also suitable for the sealing test and air tightness test of other products, as shown in the figure below
