As parts become more complicated, the cleaning process necessitates specialized equipment and unique cleaning methods.
Every parts cleaner manufacturer has a team of experts dedicated to providing solutions for a wide range of cleaning challenges. The various methods include parts cleaners equipped with baskets, CNC programming, back and front loading systems, trays, conveyors, rack systems, and rotary tables. The primary types of parts washers are water or aqueous-based, which are distinguished by the types of solutions they use in the cleaning process.
Despite the wide variety of parts washers available, they all share certain common components, including a water heater, filtration system, pumps, scrubbers, brushes, power nozzles, and an enclosure to contain the cleaning process.
Water heaters in parts washers can be powered by gas, electricity, or steam. They play a crucial role in enhancing the chemical reaction between detergents, chemicals, and solvents, which is vital for effective cleaning. Timing is critical in industrial production, as the parts washing process must align seamlessly with other production stages. To meet this demand, the parts cleaning process needs to be both quick and efficient. The water heater contributes by accelerating the chemical reaction between the solvent or cleaner and water, thus speeding up the cleaning process.
The filtration unit is positioned between the cleaning tank, where the parts are cleaned, and the storage tank, where the cleaning solution is stored for reuse. During the cleaning process, burrs, particles, and dirt are removed from the parts and absorbed into the cleaning solution. To maintain the efficiency and productivity of the cleaning process, these absorbed contaminants must be filtered out of the solution. This crucial task is handled by the filtration unit or system, ensuring the cleaning solution remains effective for repeated use.
Like all parts cleaners, various filtration systems are available, which may include a single filter or multiple filters depending on the design. The specific filters used in these units can take different forms, tailored to meet the requirements of the parts cleaner's process.
The pump transfers the cleaning solution from the storage tank to the cleaning tank, operating continuously to circulate the solution. Given the harsh conditions of the cleaning process, parts washer pumps are constructed from durable materials to withstand various environments and harsh chemicals. They function effectively at extreme temperatures and high flow rates to ensure efficient cleaning. Typically, parts cleaner pumps move 115 gallons per minute (GPM) at a pressure of 65 PSI, which is crucial for the successful operation of the parts cleaner.
Scrubbers in parts washers can be either spray nozzles or sets of brushes, depending on the design and the types of parts being cleaned. As the pump circulates the cleaning solution between the storage and cleaning tanks, part of the solution is directed to spray nozzles that apply the solution forcefully to the parts. Scrubbers play a crucial role in removing dirt and grime, especially from hard-to-reach angles and blind holes.
Nozzles are a key component in the scrubbing process of a parts washer and come in various designs depending on the washer's configuration.

What are some common accessories for parts washers, and how do they enhance the functionality of different types of parts washers? Are these accessories necessary from the beginning, or are they typically added after extended use?
Solvent filters are designed to extend the life of cleaning solvents by removing oil, grease, and other contaminants from them. This filtration process allows solvents to be reused multiple times, reducing costs and ensuring a continuous supply of clean solvents.
Parts washers are typically equipped with containers such as baskets and racks to organize and separate parts during cleaning. However, these containers can wear out or become damaged with extended use. Fortunately, manufacturers offer a wide range of replacement baskets and racks to ensure continued effective operation.
Work shelves serve multiple purposes in parts washers, including the storage of parts, providing extra space in certain models, and acting as replacements for worn shelves. Constructed from heavy-gauge steel, these shelves feature a robust metal frame for durability.
Sludge trays are designed to collect and contain residue such as grime, oil, and grease that settles at the bottom of the washing tank. This keeps the sludge away from cleaned parts, ensuring a more efficient cleaning process.
A degreaser is a powerful solvent cleaning system used with parts washers to effectively cut through grease and oil buildup. The term "degreaser" encompasses a range of products, including precision cleaners, maintenance cleaners, and carb cleaners, all designed to remove contaminants quickly and efficiently without mechanical devices or scrubbing. While petroleum-based degreasers are common, water-based degreasers are often preferred for their safety and ease of use. Degreasers are suitable for use with immersion cleaning systems and batch cleaners. Specialized types, such as ultrasonic and vapor degreasers, offer automated, repeatable cleaning processes ideal for critical applications like medical equipment and aerospace components.
A wastewater evaporator transforms water into vapor, leaving contaminants behind. This process utilizes thermodynamics by heating the wastewater to convert it into vapor. A blower then removes the water vapor from the system. Wastewater evaporators are used with parts washers to effectively separate water from contaminants collected during the cleaning process.
In modern industrial processes, which often involve lubricants, oil, grease, and other substances, cleaning parts is essential. After production, it's crucial to remove these residual materials. Parts washers provide a safe and efficient solution for this task by utilizing water, heat, agitation, and environmentally friendly chemicals.
Parts washers eliminate the need for manual labor in the cleaning process. Typically, human involvement is required only after the cleaning is finished. The entire process—handling, cleaning, rinsing, and drying—is carried out safely and efficiently by the parts washer.
Parts washers are capable of cleaning any type of part or component, no matter its size or complexity. Their diverse solutions and cleaning systems can access the most remote and intricate areas to remove contaminants. The primary limitation of parts washers is the size of the enclosure needed for the parts being cleaned.
