Product Details

Intelligent salt spray testing machine

Intelligent salt spray testing machine is designed for surface treatment of various materials, including coating, electroplating, organic and inorganic film, anode treatment, antirust oil

After anti-corrosion treatment, the corrosion resistance is tested to determine the quality of the product.

characteristic

  • Two kinds of spray are continuous / indirect spray. Programming automatic operation, write once, no need to be on duty
  • The nozzle is atomized by the brnot principle, and no crystal salt is produced.
  • Touch button setting of the control system, LCD control and operation interface are all on the same machine board, humanized vertical operation, all detection data are clear at a glance
  • According to the international salt spray test operation requirements, automatic mode and manual mode can be selected at will.
  • Power failure memory function, double over temperature protection, design and function are in line with world standards.

Box material:

  • The test box is welded with light gray PVC plate, and the temperature resistance is 85 ℃ and the structure is firm.
  • The cover of the test chamber is made of imported transparent acrylic impact resistant plate, and the edge is thickened inside and outside to prevent distortion due to high temperature for a long time.
  • It is easy to clean and operate.
  • The pressure air tank adopts sus ා 304 stainless steel high pressure and high temperature resistant reagent, which has the best heating, humidification and heat preservation effect.
  • The test sample rack is of plane dividing type, and the angle can be adjusted arbitrarily at 15 ° and 30 ° with uniform fog falling on all sides and consistent fog receiving. The test results are accurate and the number of test samples is large.
  • Unique watertight structure, no salt spray overflow.

technical backstopping

  • According to JIS, ASTM, CNS, GB standard parameter operation setting.
  • Brine spray test: NSS
  • Test chamber: 35 ℃± 1 ℃, pressure air barrel: 47 ℃± 1 ℃.
  • Corrosion resistance test: CASS
  • Temperature: 50 ℃± 1 ℃
  • Pressure air barrel: 63 ℃± 1 ℃.
  • Defogging method: use air to squeeze fog

Air supply system:

The air pressure of 1kg / cm2 is adjusted in two sections. The first section is roughly adjusted to 2kg / cm2, and the imported air filter is used with drainage function; the second section is precisely adjusted to 1kg / cm2, and the pressure gauge display is precise and accurate.

Spray mode:

  • Bernoult principle absorbs salt water and then atomizes. The atomization degree is uniform and there is no blocking crystallization phenomenon, which can ensure the continuous operation of the test;
  • The nozzle is made of tempered glass, and the spray volume and the ejection angle can be adjusted.
  • The spray volume can be adjusted by 1~2ml/h (ml/80cm2/h standard requires 16 hours for average). The measuring cylinder is embedded in installation, with beautiful appearance, convenient observation and reduced installation space.
  • Programmable spray with adjustable time of 1S-9999H (including continuous spray and interrupted spray).

Heating system:

It adopts steam direct heating mode, which has fast heating speed and reduces standby time; when reaching the specified temperature, it can automatically switch to constant temperature state, with accurate temperature control and low power consumption; pure titanium heating pipe has acid and alkali corrosion resistance and long service life.

Control system:

  • Touch button setting, LCD control and operation interface are in the same machine board, humanized vertical operation; all monitoring data are clear at a glance.
  • Siemens PLC, 32-bit automotive extremely high processor, stable and reliable performance.
  • The timing mode can be quickly changed, which is convenient to observe the test time. It can be adjusted to 0.1s ~ 99999h (h, m, s can be adjusted), and the power failure memory function is provided.
  • According to the international salt spray test operation requirements, the automatic mode and manual mode can be selected at will. Under the full-automatic mode, the machine will not work automatically (except for human factors) if the operating temperature of the machine fails to meet the test requirements.
  • The water level control system adopts DC low voltage input to ensure the safety and service life of the equipment.
  • Dual channel PID temperature control, error ± 0.5, convenient for calibration and measurement.
  • After the test, it is equipped with automatic mist eliminator, which can clearly observe the samples in the laboratory.
  • Pure silver relay with long service life
  • All day monitoring operation, no need to stay;
  • It has the function of programmable test, adjustable, high accuracy of test;
  • The upper cover of the test tank of the larger model is opened and closed automatically by the pneumatic cylinder, which is easy to operate and has good safety.

 Safety protection device:

  • When the water level is low, the power supply will be cut off automatically and the safety warning light will be on.
  • When the temperature is too high, the power supply of the heater will be cut off automatically, and the safety warning light will be on.
  • When the water level of test drug (brine) is low, the safety warning light device will light up to display and give an alarm.
  • Leakage protection function to prevent personal injury and instrument failure caused by line leakage or short circuit.

Water adding system:

Two kinds of water adding systems, automatic and manual, are used to supplement the water level of pressure drum and laboratory automatically or manually, so as to prevent the instrument from being damaged by water shortage and ultra-high temperature.
