Waterjet Is The Use Of Water Jet To Cut And Crush Objects.
Waterjet is the use of water jet to cut and crush objects.
The waterjet is to cut and crush the object by the action of the water jet. In the cutting procession of the waterjet, when the water jet contacts the object, its speed will change, but it is not known exactly. The way to make changes. And for the waterjet, how should its high pressssure intensifire be maintained?
When the pressure in the water jet reaches a certain height, the water will flow out from the nozzle of the water jet and hit the object at an ultra-high running speed, thereby causing an impact on it. However, when the impact is generated, it also causes a sudden change in the jet velocity, which causes the internal pressure of the water droplet state and the internal stress field of the contact point material to be abrupt and damage the object. In other words, the water jet droplets of the water jet interact with the object. When the droplet acts on the surface of the object, the jet can only remain flat in the first stage, and free radial motion occurs when it comes into contact with the solid matter. . Therefore, the water jet of the water jet changes the speed at the moment of contact with the object.
Since the waterjet is a tool with very powerful cutting ability, it can be used in the cutting of various materials. In addition to important accessories such as sand pipes and nozzles, the high voltage generator is also not available in the waterjet. An important part missing. In order to ensure the safety during the water cutting process, the normal operation of the high voltage generator is one of the conditions, and one of the measures to prevent the problem is to pay attention to maintenance.
The specific measures include frequently checking whether the water knife high-pressure generator cooling device is automatically started, so that the cooling water temperature is kept within the specified range; at the same time, the liquid condition should be observed frequently, and the hydraulic oil should be replenished in time according to the actual situation. If the high voltage generator is damaged by dust, it will be damaged. Therefore, dustproof devices must be installed in all parts to keep it in good working condition. In addition, it is often necessary to check the oil filter signal light generated by the water jet high pressure, so that the corresponding action can be smoothly performed. In short, if there is no problem with the high voltage generator, the probability of water knife failure will also be clearly controlled.
