Getting a right parts washer- a machine where dirty parts can be cleaned, components and equipment can be washed – is not an easy task. As with all store equipment, not all washers are evenly created.
Also, parts washers are available in a range of cleaning solutions, specifications and hygiene levels, with a variety of options. There are also different environmental concerns for different types of parts washers.
1. Most common cleaning methods used by the parts washers:
The most common methods of cleaning the parts are manual and automated methods of ultrasound and immersion.
– Manual cleaning. Usually sinks in a battery style or VAT style.
The best hand washers are suitable for low volume cleaning – less than 45 minutes per day. They are pretty much good for smaller parts, where the pollutants can be removed with a low-pressure brush, and the parts do not require a high level of cleaning.
– Automated cleaning. Automated parts washers are designed for operations where the parts are cleaned more than 45 minutes per day. In this case, as a rule, the transition to a mechanical process will save money.
Other considerations for automated cleaning:
- The number of cleaned parts daily requires a more automated approach.
- The parts being cleaned have a unique design where they cannot be effectively cleaned by manual processes (such as blind holes).
- The level of hygiene required in manual operation cannot be achieved.
The most common cleaning methods are:
High-Pressure Spray: These are machines similar to the CRF, which works like a dishwasher where the parts are cleaned by the high-pressure pump to exhibit different angles while rotating parts of the type washing rotating disks for thorough cleaning. Usually, heated and hydrated chemicals are used.
The water-based solvent is a water-based solution which may be comprised of detergents, alkaline chemicals, microbes or any combination thereof. Instead of dissolving fat or solids, water-based solvent using heat, stirring, the manufacture of soap and the time required to break down into smaller particles of powder.
“High-pressure spraying parts washers are ideal for the “harder-to-get-off stuff” which might be overheated onto a part with the help of heavier greases and oils, and are most effective for cleaning exterior surfaces”.
“The best part is that these modules are highly customizable and you can add conveyor systems, drying cycles, rinse cycles, etc.”
Ultrasonic Cleaning: With these mass-style units of bath coupling cleaner and battered portions powered by ultrasonic to produce high energy vibration bubbles contaminating exterior surfaces to a high level of cleanliness. This is the preferred way to clean holes, blind cracks and small parts.
“Although this method is more expensive than other techniques, this method is generally chosen because the process, requirements, or properly designed parts require cleaning.
Immersion Agitation: With these types of parts cleaners, and also the VAT form, the parts are immersed in the bath and agitated up and down or side by side in the tray, or sprayed with high-pressure spray in the assistance of immersion or a combination of both.
Immersion agitation of “perfect” exterior and interior cleaning, which is only sprayed, and cannot access the acoustic countertop, and to remove contaminants that require marinating to degrade effectively to remove.
“Depending on what parts you remove, simple shaking cannot provide enough action or effect to remove the contaminants, and the addition of a spray can help to dominate.”
2. What factors should be considered when choosing the best cleaning method for the application?
- Considerations include:
- Form the material for the part that needs to be cleaned.
- Design of the part(s).
- Size of the part(s).
- Parts of soil that you want to remove.
- Level of cleanliness required.
3. What cleaning chemistry to be used in the parts washer?
The most tested cleaning chemistries are organic-based solvents and petroleum, and speciality solvents.
Organic-based solvents and petroleum clean by dissolving or breaking down the contaminants. These solvents are not used in ultrasonic applications and high-pressure spray.
Speciality solvents are used to address niche cleaning applications and operations outside of routine repair and maintenance (i.e., solvents made to strip paints and inks). There are also speciality solvents designed to entertain industry specifications, like food industry and military specs.
