Definitions
- the invention relates to a method for low-pressure spray cleaning and residual dirt analysis of components using a low-pressure spray module.
- cleaning stations are also used for cleaning, in which cleaning medium is pumped through the component in a closed circuit using an adapter at high pressures.
- a low-pressure spraying module that solves the above task is that particle-free pressure generation without a pump is carried out with a storage container that is pressurized with compressed air and an exchangeable spray lance with variable diameter, shape and length is attached to the outlet side of the storage tank, which is coupled to a metering diaphragm valve can be;
- nozzles external cleaning of the components is also possible, and that the particle-laden rinsing medium which arises during spray cleaning is also collected in a collecting container in which a
- Analysis filter is installed, which filters out the particles from the rinsing medium and stores them for subsequent analysis.
- a method for low-pressure spray cleaning and residual dirt analysis of components working with such a low-pressure spray module has the following steps: A: Provide one filled with a flushing medium
- Analysis filter, and H residual dirt analysis based on the particles filtered out by the analysis filter.
- the filtering out of the particles is assisted by suctioning off the flushing medium by means of a vacuum pump arranged on the outflow side of the collecting container downstream of the analysis filter.
- the residual dirt analysis of the filtered particles can be carried out using light microscopy or scanning electron microscopy.
- FIG. 1 shows the components essential to the invention on the basis of a process flow diagram, an exemplary embodiment of the method according to the invention for low-pressure spray cleaning and residual dirt analysis, and a low-pressure spray module used therefor.
- a low-pressure spraying module is used according to the invention, the main components of which consist of a supply container Bl which is pressurized with compressed air from a compressed air source (line 1) and which is filled with a flushing medium (via a line 2), on the output side of the supply container Bl a pre-filter F1 connected and via lines 3 and 4 in rinsing medium communication with the supply container Bl spray lance S1, a collecting container B2, an in-line analysis filter F2, which is connected to the collecting container B2 via a line 5, and that from the after Flushing the component from the particle-loaded rinsing medium collected in the collecting container B2 filters out particles and stores them for their subsequent analysis, and there is a vacuum pump connected (not shown) connected via a line 6. All system parts are preferably made of stainless steel and are optimized for dead space.
- the reservoir B1 is filled with filtered rinsing medium via line 2. It can be operated as a compressed air source with a maximum pressure of about 6 bar by connecting to a factory compressed air network (line 1). The supply pressure is controlled or regulated by a valve VI located in the compressed air supply line 1. Via the injection unit Sl with
- Lance can also be used to feed the flushing medium into long through holes. So that the necessary mobility of the flushing lance S1 is ensured, the flushing lance S1 is connected to the prefilter F1 via a flexible hose 4. Between prefilter Fl and the
- Storage container Bl is located in line 3, a second control / control valve V2 for needs-based control / adjustment of the pressure and / or the amount of flushing medium to the prefilter Fl or to the flushing lance S1. Due to the exchangeable spray lance Sl, whose
- Diameter and length can vary depending on the component, and the flexible line 4 can also be used to design complex components, i.e. also through holes and blind holes drilled into the component from different sides, i.e. be sprayed out.
- the rinsing medium loaded with particles is collected in the collecting container B2 after the components have been sprayed out.
- the upper opening of the collecting container B2 advantageously widens upwards in the shape of a funnel.
- the particle-laden medium collected by the collecting container B2 is removed using the in-line analysis filter F2 the vacuum pump (not shown). The generated filter can then be examined immediately and evaluated for residual dirt determination.
- An alternative that is not covered by the invention would be the generation of pressure for the flushing medium by means of pumps, which necessitates a complex filter technology for the flushing medium in order to guarantee its high purity. Furthermore, there is a higher pressure loss, which is kept in the pump capacity.
- the process used according to the invention uses an open circuit in which the pressure can be varied in a simple manner and no complex filter technology is necessary.
- the proposed method for low-pressure spray cleaning and residual dirt analysis of components and the low-pressure spray module used for it have so far been successfully tested on components with clean-critical interior areas, e.g. Tried and tested on high-pressure pumps for diesel injection systems, injection nozzles, hydraulic units for ABS systems and on other components of motor vehicle injection systems.
