Description
Technical Field
The utility model relates to an environmental simulation test measures technical field, in particular to online automatic checkout device of weighing type salt fog settlement rate.
Background
The salt spray test equipment is test equipment for simulating temperature and salt spray climate environmental conditions. The salt spray test equipment mainly comprises a box body, a spraying system, a heating system and a control system. In the working space of the salt spray box, the compressed air of the spraying system atomizes the salt solution to form salt spray and the salt spray is settled freely. The salt spray test is mainly used for checking the salt spray corrosion resistance of the material and the protective layer thereof, comparing the process quality of similar protective layers and checking the salt spray corrosion resistance of products.
The salt spray temperature and the salt spray sedimentation rate in the salt spray test box are important technical parameters for judging the corrosion resistance, and the accuracy of numerical values of the salt spray temperature and the salt spray sedimentation rate is related to the product test result, so that the value tracing of the salt spray temperature and the salt spray sedimentation rate of the salt spray test box is very important. According to the requirements of GB/T5170.8 and GB/T2423.18, the salt mist sedimentation rate in the salt mist test box in the salt mist test is (1.0-2.0) mL/(h.80 cm) 2 )。

In gbj150.11a-2009, it is even required to measure the salt spray settling rate every 24 hours during spraying. However, the existing visual measurement method has the following defects:
1. because the salt spray sedimentation rate test time in the salt spray test reaches 16 hours or even 24 hours, it is difficult for field detection personnel to control the salt spray sedimentation condition in real time, and the problems of possible spray tower nozzle blockage and the like are difficult to find in time.
2. The salt spray settlement rate data is collected by the detection personnel working for a long time, so that the working efficiency is reduced, and social resources are wasted.
3. When the existing manual visual measurement method is used for reading the numerical value of the measuring cylinder, certain personnel errors can be caused, and if no vertical reading exists, the manual reading causes reading deviation. Especially for a large walk-in salt spray laboratory, the detection personnel need to perform exploration operation under the condition of extremely low visibility, which also brings certain reading error to the measurement result.
4. The salt spray environment will also harm the health of the examining person, such as the lung mucosa, skin and eyes.
Therefore, the automatic real-time measurement and inspection of the salt spray sedimentation rate of the salt spray test equipment are necessary.
