7, with the power failure time memory function, so that after the call continue to complete the remaining time of the test work according to the original time, with double overtemperature protection, insufficient water level warning, to ensure the safety of use.

6. Spray method

1. Bernoult principle absorbs salt water and atomizes it. The atomization degree is uniform through the salt spray disperser formed by standard mold, and the test results at different points in the laboratory are more average and accurate.

2. The nozzle is made of tempered glass, which can adjust the spray amount and spray Angle and ensure no crystal blocking for 4000 hours.

3. The measuring cylinder adopts built-in installation, with beautiful and tidy appearance, convenient operation and observation, reducing the installation space of the instrument.

Vii. Air supply system

Air pressure of 1Kg/cm2 is adjusted in two stages to ensure stable and reliable spray pressure.The first section is roughly adjusted 2Kg/cm2, with imported air filter and drainage function.The second stage is precision adjustment of 1Kg/cm2, showing precision and accuracy.

Viii. Safety protection device:

1. The pressure saturation barrel in the laboratory is made of SUS304# stainless steel, which is more resistant to pressure and corrosion;

2. When overtemperature occurs, automatically cut off the power supply of the heater, and the safety warning lamp device displays dynamically.

3. When the test drug (saline) water level is low, the safety warning lamp device will display dynamically.

4. Leakage protection function to prevent personal injury and instrument fault caused by circuit leakage or short circuit.

5. Safety protection: liquid expansion safety temperature controller 0~120℃ (Italian EGO) is adopted for the heating tank of pressure saturation barrel in the laboratory.Automatic and manual water adding systems are adopted to replenish the pressure barrel and the water level of the laboratory automatically or manually, so as to prevent the ultra-high temperature of water shortage from damaging the instrument.

Ix. Advantages of intelligent touch screen salt spray testing machine:

1. Remote SMS alarm and management: this testing machine can be equipped with SMS alarm module. When water shortage, brine shortage and overtemperature in the laboratory occur on the testing machine, SMS alarm information can be automatically sent to the management personnel in time to prompt the operator to timely supplement the corresponding water level or deal with emergency.The management personnel can also send inquiry instructions to the equipment at any time. The equipment will automatically summarize the current test situation and give feedback to the equipment management personnel by SMS.In addition, when managers wish to suspend the test, they can send the suspension information to the equipment, and the salt fog testing machine will automatically suspend the operation to avoid any unexpected situation.

2. The touch screen comes with standards and instructions: salt spray test standards and salt spray test instructions can be checked at any time at the "help document" of the main interface, without users searching for standards and various test methods.The content basically covers all the basic operation of the salt spray testing machine.The test is guaranteed to proceed safely at any time.

3, low-pressure start solenoid valve: all solenoid valve low-pressure start, service life can reach the ordinary solenoid valve 3 to 4 times the time.

4, reliable touch screen: industrial touch screen, easy to touch and sensitive, can normally touch more than 400,000 times.

5, closed circuit design: completely closed circuit design, any fine salt fog particles can not enter the main circuit box, compared with the ordinary salt fog box open circuit box, has a fairly strong anti-corrosion function, at the same time, the whole machine life will be greatly extended.

6, modular design: the whole machine adopts modular design, each function module adopts plug and pull wiring, maintenance and repair is not only very convenient, but also more cost saving.

7, water shortage automatic protection: automatic low water level protection, when there is a water shortage, if there is access to the water pipe, the corresponding water filling solenoid valve will automatically open;If the user is not connected to the water pipe, the salt spray testing machine will be in automatic standby state (stop the current test to protect the machine from dry burning test), and the machine will continue to run after the user manually fills the corresponding water level.

8. One-key energy saving function: this salt fog testing machine has the function of "one-key energy saving". During the test, if the user chooses the function of "one-key energy saving", the machine will adjust the output in time according to the situation.

9. Setting of "temperature zone" to improve the test accuracy: this testing machine can set the test temperature zone. For example, we conduct neutral salt spray test.So only when the temperature of the laboratory is stabilized at 33℃~37℃,

At the same time, when the pressure barrel temperature is stable between 45℃ and 49℃, the salt fog testing machine will automatically conduct the test, otherwise the equipment will not be timed and sprayed because the temperature is outside the test range.This setting can greatly reduce the test error and improve the test reliability and accuracy.

10, type of test setup: this salt spray tester can be commonly used NSS (salt spray), AASS (acid salt fog) and CASS (speed copper salt fog) test, each test are preset in the main interface of the "test Settings", and only requires the user to choose any kind of test, the corresponding test type interface has the test solution formula of the current test profile and related matters needing attention, at the same time, the default temperature and test time, the test time can be modified by the user, including users decide whether to carry on the continuous experiment or circular.

Of course, if users need to set the required temperature, they can set the relevant temperature value and time in the "custom test".

At the same time, the test device can also carry out salt spray test of more complex programs. Each group of tests can carry out 20 stages of salt spray type test, and each stage can be set with different laboratory and saturation bucket temperature values (which need to be set within the specified range), and different periods of time and spray switch conditions can be set.

The rich type design can meet the requirements of the increasing number of salt spray test types of users. Compared with the traditional salt spray machine, an intelligent touch screen salt spray testing machine can completely replace the test requirements of several ordinary salt spray testing machines.Help customers save cost and improve test efficiency.

11. Password protection: this salt fog testing machine has the function of password management. Only after the management personnel of this salt fog machine input the correct password can the normal management and operation of this equipment be carried out, to avoid unnecessary trouble caused by the wrong operation of the salt fog testing machine by unrelated personnel.
