Equipment Description:

The pre-treatment equipment for fire-fighting equipment is a key device used for surface cleaning, rust removal, anti-corrosion, spraying and other pre-treatment of fire-fighting equipment (such as fire extinguishers, fire hydrants, sprinkler heads, etc.), ensuring that the equipment is corrosion-resistant, durable and meets safety standards. Its core functions include: surface degreasing, phosphating treatment, passivation, drying and preparation before spraying.
Typical technological process
‌ degreasing cleaning ‌, ‌ washed ‌, ‌ derusting ‌, ‌ secondary water ‌, ‌ watch/phosphating ‌, ‌ passivation ‌, ‌ dry ‌, ‌ spraying
This equipment, through modular design, takes into account both efficiency and environmental protection, and is a core device in the manufacturing and maintenance of fire-fighting equipment.

Main structures and components:

Main structure and core components
I. Main Structure
1. Pretreatment tank ‌
Function ‌ : To hold cleaning agents, rust removers, phosphating solutions and other chemical agents, and to complete immersion or spray treatment.
Material ‌ : Acid and alkali resistant stainless steel (e.g. 316L) or PP plastic, strong corrosion resistance.
2. Conveying system ‌

Function ‌ : To transport the equipment in the process sequence to each processing stage to ensure continuous operation.
3. Sprinkler system ‌
Make up ‌ : high-pressure nozzle, circulating pump, pipe.
Function ‌ : Perform high-pressure flushing on the surface of equipment to remove oil, rust and residue.
4. Drying system ‌
Equipment ‌ : hot air circulation device or infrared drying box.
Objective ‌ : To quickly remove surface moisture and provide a dry substrate for subsequent spraying/anti-corrosion treatment.
Ii. Core Functional Components
1. Filter device ‌
Type ‌ : magnetic filter, bag filter.
Function ‌ : To remove impurities from the treatment solution and extend the service life of the liquid.
2. Heating device ‌
Form ‌ : Electric heating tube, steam heater.
Application ‌ : Maintain the temperature of the treatment bath solution (e.g., the phosphating solution needs to be kept at a constant temperature of 40-60℃).
3. Control system ‌
Hardware ‌ : PLC controller, touch screen.
Function ‌ : Automatically adjust parameters such as processing time, temperature, spray pressure, etc.
4.‌ Environmental-friendly components ‌
