Project Purpose:
- Determine cause of frequently clogging nozzles of the automatic parts washer
- Develop procedures to resolve clogging issue and restore productivitySlide3
Automatic Parts Washer Information:
- Spray nozzles frequently clog with particles
- Time delays due to clogged nozzles
- All parts required to be washed in parts washer
- Only alternative available due to EPA regulationsSlide4
Brainstorming List of Potential Causes:
- Excess calcium deposits in water system
- Incompatible detergent used in parts washer
- Hard water being used
- Small chips from parts
- Dirt in water supply system
- Paint chips from washer parts
- Possible chemical reaction during use Slide5
Cause and Effect Diagram:

Cause and Effect Diagram Analysis:
Soap Build-up in Bottom of Tank
Main Problems
- Improper tank cleaning procedures
- Increased concentration of soap-water solutions due to water evaporation
- Improper tank heating causing solution to not properly dissolve
Secondary
Problems
- Lack of filtration allowing particles to reach nozzlesSlide7
Possible Actions to Take:
1. Clean tank properly after during soap-water solution changing
2. Change soap-water solution mixture when topping off tank after evaporation
3. Monitor water temperature to ensure proper heating
4. Add filtration system to prevent particles from reaching spray nozzles
Driving Forces
Restraining Forces
Restore
productivity -
Reduce maintenance downtime - Elimination of time delays - - Cost to add filtration system- Additional time to clean tank properly
Force Field Analysis:
Parts Washer Process ModificationsSlide8
Follow up Actions:
Task personnel responsible for parts washing to immediately implement options 1 and 3 of actions to take which are:
1
. Clean tank properly after during soap-water solution changing
3
. Monitor water temperature to ensure proper heating
Monitor these actions for 1 week to determine if this resolves the problem.Slide9
Evaluation of Corrective Actions:
If it is determined that the parts washer nozzle clogging is not resolved after the 1 week monitoring period, the following steps will need to be implemented and monitored for an additional week.
2. Change soap-water solution mixture when topping off tank after evaporation
4
. Add filtration system to prevent particles from reaching spray
nozzles.Slide10
Plan of Action:
- All involved will need to monitor the results of the of all steps as they are implemented.
- Detailed tracking will need to occur to ensure only the steps required are implemented.
- If situation is resolved after implementation of steps 1 and 3 then no further action will be required.
- If not, implement steps 2 and 4 and monitor.
- If it is determined that steps 2 and 4 resolved the nozzle clogging, no further action will be required.
- If problem still isn’t resolved begin the entire process over taking all previous actions into consideration.Slide11
Follow Up:
- After implementation of steps 1 and 3, it was determined that there were still nozzle clogging issues and productivity was still slowed up because of it.
- Steps 2 and 4 were then implemented and the nozzle clogging issue was resolved. The filtration system and soap-water mixture cured the problem.
- The parts washer system will be closely monitored for an additional month to ensure the implementation of the 4 steps continue to work.Slide12
