Structure and material of JZY-800 sand dust test chamber:

1. The inner tank is made of SUS304 stainless steel plate, and the shell is electrostatic sprayed with cold rolled plate. The door of the test chamber is a toughened transparent glass door, and the lower part of the door is an electrically controlled area. Talc powder simulating sand dust is placed in the hopper at the lower part of the test chamber. The circulating fan and automatic jar are used to blow talcum powder into the upper part of the working chamber through a 75 μ m square hole mesh to promote the formation of high-density dust mist in the test space, and the test object is tested< br />
2. Visible glass door with dust scraper, convenient for observing the condition of the tested sample in the test chamber

3. High quality fixed PU movable wheels are used at the bottom of the test chamber

JZY-800 sand dust test chamber circuit control system:

1. The imported programmable controller is used to effectively ensure that the test runs according to the standard< br />
2.、“ Chint” Executive components< br />
3. The time of the dust blower automatically alternates< br />
4. The time of vibration and vibration stop is automatically alternated< br />
5. The programmable controller has four output points to execute four programs at different times simultaneously< br />
6. Each output point of the programmable controller is controlled by two time periods (i.e. start time and stop time)< br />
7. The programmable controller can control the time of dust blower, dust vibration and total test time separately or collectively< br />
8. The test time * is 99 hours and 59 minutes< br />
