The casting multi-way valve is the control element of the main engine of the construction machinery, and one of the main parts is the casting valve body. The cleanliness of the casting valve body is the key to the manufacturing of the casting multi-way valve, and it is also one of the processing difficulties. However, the shape of the casting valve body is complex. There are many types and quantities of blind holes, deep holes, oblique holes, and cross holes. After machining, there are more iron filings in the holes and undercut grooves. At the same time, there are sticky sand on the surface of the castings, Oxide scale, rust, etc. should be cleaned up.
Common cleaning methods such as ultrasonic cleaning, low-pressure water flushing, low-pressure spray cleaning, dipping, and rinsing cannot be cleaned thoroughly, and cleanliness is one of the important factors that cause the failure of the hydraulic system. Therefore, improving the cleanliness of the casting valve body is of great significance to improving the working performance and service life of the casting multi-way valve and improving market competitiveness.
The high-pressure cleaner uses water as the working medium. Usually, the power-driven pump completes a suction and discharge process of water to convert ordinary water into high-pressure and low-velocity water, and then delivers it to the high-pressure pipeline to give it a certain amount of energy When the nozzle reaches the nozzle, the nozzle can convert the high-pressure and low-velocity water into a high-pressure water jet; when the impact force of the high-pressure water jet is greater than the adhesion force of the dirt and the surface of the object, it will peel off the dirt and wash it away, and finally achieve precision cleaning. Purpose, at the same time, it can remove some small flashes and burrs after machining.
