Proper cleaning and maintenance of dip spray washing machines are essential to ensure consistent performance, prolong equipment life, and maintain hygiene standards in industrial or commercial settings

These machines are commonly used in applications ranging from automotive parts cleaning to precision component degreasing, and their effectiveness depends heavily on how well they are cared for

Failing to perform regular servicing may result in blocked spray heads, diminished fluid output, dirty rinse baths, and expensive production halts

Start every shift with a visual check for dirt accumulation, chemical deposits, or fluid seepage

Remove any accumulated dirt or particles from the spray chambers, conveyor belts, and drain areas

For optimal hygiene, use a microfiber cloth or gentle brush to remove residues and prevent inter-cycle contamination

Ensure the machine is fully powered down and depressurized prior to any manual maintenance to guarantee worker safety

The spray nozzles are among the most sensitive parts of the system and demand consistent maintenance

Accumulated contaminants—such as hard water scale, paint fragments, or固化 chemical films—can obstruct flow paths and disable nozzle function

Check every nozzle each shift and purge buildup with a soft-bristle tool or manufacturer-approved cleaning agent

When clogs persist, immerse nozzles in a diluted pH-balanced solution recommended by the maker, then rinse extensively with pure deionized water

Metal tools, pins, or drills must never be inserted into nozzle openings, as they will irreversibly compromise spray accuracy

Filtration units must be reviewed on a consistent basis

Most dip spray machines are equipped with inlet and outlet filters to trap contaminants before they reenter the cleaning bath

Follow the vendor’s recommended interval—usually 100–200 hours—or replace filters immediately if flow or pressure declines

Blocked filters impair cleaning performance and force the pump to work harder, accelerating mechanical degradation

Daily evaluation of cleaning and rinse liquid states is mandatory

Regularly measure solution strength using calibrated test strips or refractometers, adjusting or replacing based on readings

Solutions must remain clear and free of visible particles, discoloration, or suspended contaminants

Empty and rinse the tanks on a weekly basis—or after each heavy-load cycle, particularly when changing materials or chemicals

All spent fluids must be captured and discarded in compliance with regional environmental and hazardous waste laws

Regular service of the pump and drive motor is vital for long-term reliability

Lubricate moving parts as recommended in the equipment manual, and listen for unusual noises such as grinding, whining, or knocking, which may indicate bearing wear or misalignment

Inspect hoses and seals for Tehran Poshesh cracks, swelling, or leakage, and replace any that show signs of deterioration

Keep the pump intake free of obstructions to prevent cavitation, which can damage the impeller over time

Periodic calibration of digital controls and sensors is necessary to guarantee accurate thermal, pressure, and timing parameters

Incorrect system settings can result in substandard cleaning or unnecessary waste of cleaning agents

Use a certified technician for calibration if the machine has digital controls or programmable logic systems

Keep a comprehensive maintenance log that documents all preventive actions, replacements, and service events

This not only helps track equipment history but also supports compliance with safety and quality standards

Train all operators on basic cleaning procedures and encourage them to report anomalies immediately

Consistent application of these procedures ensures peak system performance, minimizes breakdowns, and certifies that every output adheres to the highest standards of hygiene and precision
