Here is a very detailed and standardized installation guide for Cyclic Corrosion Test Chambers. Please be sure to follow it strictly, as correct installation is fundamental for the long-term stable operation of the equipment and the accuracy of test results.Important Safety Warning:

  • ••Before starting installation, carefully read the accompanying "User Manual". There may be slight differences between brands and models.
  • ••Installation and operation must be performed by trained professionals.
  • ••Ensure all power, air, and water supplies are turned off.

Step 1: Pre-Installation Preparation

1.1 Site Selection and Environmental Requirements

  • ••Space Requirements:​ Reserve at least 60-80cm of space around the equipment for heat dissipation, maintenance, and cabling. Ensure adequate ceiling height.
  • ••Floor Requirements:​ The floor must be level, solid, and capable of supporting the weight of the equipment (weight increases significantly when filled with water). Use a level to check.
  • ••Environmental Conditions:
    • ••Temperature:​ Install the chamber in a well-ventilated room with an ambient temperature between 15°C and 30°C. Avoid direct sunlight.
    • ••Humidity:​ Relative humidity ≤ 85% to prevent condensation.
    • ••Air Quality:​ Avoid strong vibrations, strong electromagnetic interference, high concentrations of dust, and corrosive gases.

1.2 Utility Preparation

Cyclic chambers typically require three utilities: Electricity, Water, and Air. Prepare these before installation.

  • ••Electrical Power:
    • ••Confirm the required voltage (e.g., AC 220V or AC 380V) and frequency (50/60Hz) match the site power supply.
    • ••A dedicated circuit breaker or leakage protection breaker is essential. Do not share the circuit with other high-power equipment.
    • ••Use copper core cables with sufficient wire gauge according to the equipment's power requirements and ensure proper grounding​ (grounding resistance ≤ 4Ω). This is critical for safety.
  • ••Compressed Air:
    • ••Pressure Requirement:​ Typically 2 ~ 4 bar​ (approx. 0.2 ~ 0.4 MPa). Refer to the equipment nameplate or manual.
    • ••Quality Requirement:​ Crucial for stable operation, especially for chambers with drying functions. Must be clean and dry compressed air.
      • ••Solution:​ Must be equipped with an Air Compressor, Refrigerated Air Dryer, and Three-Stage Precision Filtration System​ (including oil-water separation, particulate removal, and activated carbon oil removal). Ensure the air supplied to the chamber is oil-free, water-free, and dust-free.
  • ••Water Supply:
    • ••Salt Solution Tank / Humid Water Tank:​ Requires Deionized Water (DI Water) or Purified Water​ with a conductivity of ≤ 20μS/cm. Never use tap water directly to prevent scaling and clogging.
    • ••Saturation Barrel (Pressure Vessel):​ Used for heating and humidifying air, also requires deionized or purified water.
    • ••External Chamber Cooling Water (Specific Models Only):​ For water-cooled models, prepare a cooling tower and circulating water system. (Air-cooled models do not require this).

Step 2: Equipment Positioning and Initial Inspection

  1. 1.1.Unboxing Inspection:​ Carefully remove the packaging. Check the equipment and accessories (e.g., V-shaped sample racks, rods, funnels, measuring cylinders, sealing water tank, exhaust pipe) against the packing list for completeness and any transport damage.
  2. 2.2.Moving into Position:​ Use a forklift or hydraulic pallet truck to move the equipment smoothly to the predetermined location. Never drag the equipment directly on the ground, as this may damage components underneath.
  3. 3.3.Remove Shipping Secures:​ Inspect the interior and remove any straps or foam used to secure movable parts like the chamber body or spray tower during transport.
  4. 4.4.Leveling:​ Use a spirit level to check if the chamber is level. If not, adjust the leveling feet or casters (if equipped with locks) to ensure the chamber is stable and does not rock.

Step 3: Pipe and Cable Connection

3.1 Air Line Connection

  • ••Connect the prepared clean, dry compressed air line to the chamber's designated inlet (usually located on the back or side).
  • ••It is advisable to install a manual ball valve​ before the inlet for easier maintenance.
  • ••After connection, open the air supply slightly and check for leaks at all connections by listening or using a soapy water solution. Ensure connections are secure.

3.2 Water Line Connection

  • ••Salt Solution Replenishment:​ Connect the DI water pipe to the auto-fill valve interface of the salt solution tank.
  • ••Humid Water Tank / Saturation Barrel Replenishment:​ Connect another DI water line to the corresponding replenishment interface.
  • ••Installing a manual valve before each water inlet is recommended.
  • ••Note:​ For initial use, you will need to manually add a certain amount of DI water to the salt solution tank, humid water tank, and saturation barrel until the water level reaches the middle or high mark of their sight glasses.

3.3 Drain Pipe and Exhaust Pipe Connection

  • ••Drain Outlet:​ The chamber typically has one or more drain outlets. Use the provided hose or purchase PVC pipes to connect the drain outlet to a floor drain. Important: The drain pipe must have a U-trap (water seal) to prevent salt mist from escaping.
  • ••Exhaust Outlet:​ Connect the exhaust outlet on the top of the chamber to the outdoors using the provided exhaust pipe. The pipe should slope downward to prevent condensation backflow. The exhaust terminal should be away from people and flammable materials.

3.4 Power Connection

  • ••A qualified electrician should connect the prepared power cable to the equipment's terminal block, strictly following the "L-Live, N-Neutral, PE-Ground"​ wiring scheme.
  • ••After connection, ensure all terminations are tight.

Step 4: Post-Installation Check and Preliminary Debugging

Conduct a final check before turning on all utilities.

  1. 1.1.Seal Check:​ Inspect the chamber door gasket for damage and ensure the door closes tightly.
  2. 2.2.Internal Check:​ Inspect internal components like heaters, sample racks, and nozzles for any abnormalities.
  3. 3.3.Utility Activation Sequence:
    • ••Step 1: Turn on the water supply.​ Open the valves, observe if all tanks fill to the set water level normally, and check for any leaks.
    • ••Step 2: Turn on the air supply.​ Slowly open the air valve, observe if the pressure gauge reaches the set value (e.g., 2.5 bar), and check all air connections for leaks using a soapy water solution.
    • ••Step 3: Turn on the electrical power.​ Switch on the main circuit breaker.

Step 5: Initial Startup and Functional Testing

  1. 1.1.Power On:​ Turn on the main power switch of the chamber. The touchscreen or control panel should illuminate normally.
  2. 2.2.Parameter Setting Test:
    • ••Salt Spray Mode Test:​ Set a simple salt spray program (e.g., 35°C, 1 hour). Observe if the heating and spraying systems activate normally. Visually check if the spray is even, and use the measuring cylinder to check if the沉降量 (sedimentation rate) is within the standard range (e.g., 1~2 ml/80cm²/h).
    • ••Drying Mode Test (Core Cyclic Function):​ Set a drying program (e.g., 60°C, 20% RH). Observe if the heater and blower work correctly and if the chamber temperature rises quickly and stabilizes.
    • ••Humid Mode Test:​ Set a humid program (e.g., 60°C, 95% RH). Observe if the humidification system (usually steam humidification via a boiler) works and if temperature and humidity can reach and maintain stability.
    • ••Condensation Mode Test (if applicable):​ Set a condensation program and observe if the function simulating natural humidification works correctly.
  3. 3.3.Safety Device Test:​ Test safety features like over-temperature protection and low water level protection to ensure they are sensitive and effective (refer to the manual for testing methods).

If all the above steps are completed successfully and all chamber functions operate normally without leaks or alarms, the installation is complete.

Follow-up Recommendations

  • ••Routine Maintenance:​ Regularly clean the salt solution tank, change water in the saturation barrel, and clean the nozzle to prevent scaling and clogging.
  • ••Operator Training:​ Ensure operators are fully trained on the equipment's capabilities, operating procedures, and safety precautions.
