Usually cleaning steps

1. Ultrasonic cleaning

Please refer to the installation instruction of the ultrasonic cleaning machine connect the temperature control sensor signal line, the ultrasonic driving line, the heater control line between the electric control cabinet and the main machine, and connect the 380VAC power supply, install the upper pipe, drain pipe and overflow drain pipe of the washing machine.

2. Ultrasonic cleaning tank water

Add appropriate amount of water to the cleaning pool, the liquid level to immerse the parts to be cleaned as the standard, not more than three-quarters of the pool.

3. Ultrasonic cleaning and heating

Start the electric heating switch, the water temperature adjustment knob on the white scale bias moderate temperature (should be about 40 ° C) . The highest temperature of the detergent should not exceed 70 ° C in the use of the washing machine.

4. Add detergent to the ultrasonic cleaner

When the water temperature rises to 40 ° C or so, add the parts detergent into the cleaning pool (usually about 5kg at a time) , slowly stir the water to make it fully dissolved (at this time can also start the ultrasonic or gas equipment to start mixing) .

Preparation of ultrasonic cleaning machine

Before cleaning the most appropriate to do the first part of the surface of the stain (such as dust cover on the outside surface will have some dust, cylinder-type parts in the shell curve changes will accumulate a lot of thick and easy to remove the oil and dirt) a simple cleaning, in order to extend the service life of the cleaning fluid.

Ultrasound can be used for precise cleaning, but the amount of Waste treatment in the sludge is poor. Therefore, yellow or watery sludge should be removed as far as possible during the preparation process.

Ultrasonic cleaning machine parts placement

Put the spare parts in the reinforcing bar basket and put them into the cleaning basin gently. When many spare parts are put into the basket at one time, they should be distributed evenly in the basket as far as possible.

7. Turn on the ultrasonic cleaning machine

When the ultrasonic cleaning machine is working normally, the ultrasonic wave is emitted from three directions at the same time. Press the down side to start the ultrasonic wave, and the two sides of the ultrasonic wave are already started. Turn the power adjusting knob to the right and press the down side to start the ultrasonic wave. And turn it to the appropriate power, at this point in time LED display display at the bottom of the current stage of ultrasonic power values.

8. Turn off the ultrasonic cleaning machine

In order to turn off the machine in the cleaning process, the power knob must be set to the lowest. Press stop bottom ultrasound again. Cleaning time according to the status of the surface cleaning grasp.

9. Ultrasonic cleaning machine overflow

If there is too much oil slick on the liquid level of the cleaning pool, it is reasonable to open the overflow equipment of the cleaning machine to remove it, in order to avoid re-contamination of the cleaning work piece.

The steps are as follows: open the overflow valve and fill the sink with water or cleaning fluid until the cleaning fluid gradually overflows (it is recommended to use a scraper-type device to cut the oil in the direction of the overflow outlet to facilitate its rapid flow) , maintain overflow drain valve always closed to prevent accidental overflow from causing ground damage.

10. Preparation of ultrasonic cleaning machines

Remove the cleaned parts and use the Compressed air to completely clean the remaining cleaning fluid in the holes of the parts and to dry the surface layer (a blowtorch is recommended for Air compressor applications) . If possible, in the washing machine around the best equipped with a sink. In order to take out the spare parts for rinsing.

11. Ultrasonic cleaner solution

When the washing machine washed too many parts, cleaning agents in the content of oil and dirt will be very high, so the ultra-ultrasonic emulsifying effect. Cleanser will be too dirty because of sticky and weak cavitation ability, not suitable for normal use. It is suggested that the user set up a water storage bucket to be used with a washing machine to precipitate dirty detergent and to recycle it again to control the cost.

12. The immersion promotion of ultrasonic cleaning machine

Many parts, such as cylinder heads, pistons, connecting rods, turbocharged turbines, intake and exhaust pipes, carry carbon deposits on these parts, and some are lighter and can be cleaned easily, but some are very heavy, in which case the necessary soaking-softening process for the workpiece will result in better cleaning practices.

Pressure cleaning

1. High pressure cleaning

Cleaning pressure in 1 mpa (about 10 kg force/cm 2) and above is called high-pressure cleaning, it is usually relying on high-pressure water column (or cleaning liquid column) impact energy to achieve the effect of scale cleaning. Because the impact energy is relatively large, the usual stains can be cleaned down, and the blind area of the parts to be cleaned, blind holes and lumen can be cleaned very clean. If the cleaning fluid is used for high-pressure cleaning, a large number of foam will be formed when the high-pressure washing parts, so that less foam recycling system, which affects the increase of cleaning pressure. Therefore, the majority of high-pressure cleaning water (hot water) ; if you need to clean the parts with heavy oil stains, then choose the temperature of 80 ° C or so of hot water. Occasionally should not be used according to the demand of low concentration of cleaning fluid.

The common domestic high-pressure cleaning pressure is about 1.5 ~ 2.0 mpa, in such a pressure under the actual cleaning effect and economy are very good. High pressure cleaning at home and abroad used by the cleaning pressure is relatively high, up to about 5 mpa; if the application of hot water for high pressure cleaning, cleaning pressure is higher (5-7 mpa) .

High pressure cleaning is the practical application of high pressure jet technology in cleaning. It has been widely used abroad, and the basic theory of high pressure jet and its application have been studied a lot. High-pressure cleaning has been widely used in China to remove rust from ships and remove marine organisms from the outside of their hulls, and rolling stock repair departments have started to use high-pressure cleaning to clean bogies and car bottoms, the actual effect obtained is very good, in addition to the stain can be removed, rust, old paint layer can be cleaned down.

In order to reduce the pollution to the environment and save the water, according to a set of waste water recycling treatment device will be used after the sewage purification. The cost of high-pressure water flushing is not very high.

High-pressure cleaning for the liquid supply system (mostly for the pump and its driving mechanism) and the infusion system (mostly for the high-pressure pipeline and its connection device) requirements are very high. In addition, it must be pointed out that high-pressure liquid column or water column in close proximity to human health hazards, but in the actual time to pay attention to safety precautions.

2. External pressure cleaning

Cleaning pressure in the range of 300-1000 KPA pressure cleaning called external pressure cleaning. The cleaning effect of external pressure cleaning is also very good. The main features are low cleaning pressure and no requirement for flushing equipment. Therefore the equipment is concise and clear, the manufacture is simple.

Common external pressure cleaning pressure of 400-600 kpa, usually using alkaline cleaning solution and metal cleaning solution as a cleaning medium. Pressure cleaning of diesel locomotive parts and components, mostly external pressure cleaning.

3. Low-pressure cleaning

Cleaning pressure in the following 300 kpa pressure cleaning called low pressure cleaning. Because the cleaning pressure is relatively low, and the impact energy of the liquid column is also relatively small, so sometimes called low-pressure cleaning for washing or rinsing.

Low pressure cleaning is mainly used for parts with light stain levels, outside of the production process for products such as bearings, or as the last step of the cleaning process, rinse with low pressure water to clean the residual cleaning fluid on the part. The final category of the premise, usually using hot water cleaning, easy to eliminate the dry after cleaning.
