Change of water jet velocity during water jet cutting and maintenance of intensifier pump

The water jet is used by the water jet to cut and break the object. In the cutting process of the water jet, when the water jet contacts the object, its speed will change, but I don't know in what way. And for the water jet, how to maintain its high-voltage generator?

When the pressure in the water jet reaches a certain height, the water will flow out of the nozzle of the water jet and shoot on the object at an ultra-high running speed, thus impacting it. However, when the impact occurs, it will also cause sudden changes in jet velocity, which will lead to sudden changes in the internal pressure of water droplets and the internal stress field of the material at the contact point, and will damage the object.

In other words, the water jet droplets of the water jet interact with the object. When the droplets act on the surface of the object, the jet can remain flat only in the stage, and free radial movement will occur once it contacts solid substances. Therefore, the speed of the water jet changes at the moment it contacts the object.

Since the water jet is a tool with very strong cutting ability, it can be used in the cutting of various materials. In addition to the important accessories such as abrasive nozzle, the intensifier pump is also an indispensable important part of the water jet. To ensure the safety of water cutting process, the normal operation of high-voltage generator is one of the conditions, and one of the measures to prevent problems is to pay attention to maintenance.

The specific work to be done includes frequently checking whether the cooling device of the wwaterjet intensifier pump starts automatically to keep the cooling water temperature within the specified range; At the same time, it is also necessary to regularly observe the liquid condition and replenish the hydraulic oil in time according to the actual situation. If the intensifier pump is disturbed by dust, it will also be damaged. Therefore, dust-proof devices must be set at all parts to keep it in good working condition.

In addition, it is often necessary to check the oil filter signal light of the high pressure of the water jet, so that its corresponding role can be played smoothly. In short, if there is no problem with the intensifier, the failure probability of the water jet will also be significantly controlled.
