High pressure water knife cutting machine maintenance process

High pressure water knife cutting machine is a kind of cutting equipment commonly used in industrial production, after a long time of operation and use, there may be a variety of problems, affecting its normal work. Therefore, regular maintenance is necessary. The following will introduce the maintenance process of the high-pressure water knife cutting machine to ensure its long-term stable operation.

Step 1: Clean the equipment: Turn off the power and clean the surface and internal components of the machine with a clean cloth. Special attention should be paid to the removal of waste residue and sediment, so as not to affect the normal operation of the equipment. You can use a colorless transparent cleaner to wipe, but be careful to avoid detergent dripping into electrical parts.

The second step, check the hydraulic system: check the fluid level of the hydraulic tank to ensure that it is in the proper position. Suitable hydraulic oil can be added if necessary. Check the tubing for wear or leakage and replace it if necessary. Check the working pressure of the hydraulic system to ensure that its normal operation is within the specified working range.

The third step, check the water system: check the water level of the tank to ensure that it is sufficient to supply the cutting work of the high-pressure water knife. Check the working status of the pump to ensure its normal operation. Check whether water pipes are worn or leaking, and repair or replace them if necessary.

Step 4, check the cutting head: check whether the fixing screw of the cutting head is tight to ensure that the position of the cutting head is stable. Check the wear of the cutting head, and replace the cutting head in time if necessary. Check the nozzle of the cutting head to ensure that the nozzle bore is correct and clean without clogging.

Step 5, check the electrical system: Check that the power connection of the electrical system is stable and not loose. Check the working status of the control panel to ensure that all indicators are on properly. Check all fuses to make sure they are in order. If necessary, electrical testing instruments can be used for more detailed inspection.

The sixth step, lubrication equipment: check the lubrication of the equipment, add or replace the lubricating oil in time. Check the lubrication of bearings and transmission parts to ensure that they are working properly.

Step 7, functional test: After completing the above maintenance work, restart the device and carry out functional test. Test the performance of the cutting machine under different working conditions to ensure its normal operation.

Principle of water knife cutting machine

Water jet cutting machine is a kind of advanced equipment that uses high-speed jet water to cut materials. It uses the impact and speed of the water flow to precisely cut various materials such as metal and stone into the desired shape and size. The principle of water knife cutting machine can be simply described as follows.

Water knife cutting machine through a water source, the normal pressure of water into the high pressure pump. High pressure pumps increase the water pressure to very high pressures, generally above 4000 bar. This high pressure water can reach very high speeds.

Next, the water, supercharged by a high-pressure pump, is fed into an accelerator. The accelerator is a closed system in which water forms a high-speed, rotational flow. This rotating stream of water passes through the narrow outlet of the nozzle, forming a high-speed water jet.

This high-speed water jet then hits the surface of the material being cut through the nozzle. With its high speed and impact force, the water jet crushes and breaks the intermolecular bonding strength on the surface of the material. In this way, the material is separated into small pieces or cuts are formed.

In the cutting process, in order to increase the cutting effect, some abrasive is often added to the water flow. These abrasives are sprayed onto the surface of the material with high-speed water flow, accelerating the cracking and cutting of the material.

With the impact of water flow and abrasive on the material, the cutting process will generate more heat. In order to cool the material and control the temperature, water knife cutters usually set up a cooling system. The cooling system continuously sprays coolant over the cutting area to reduce the temperature.

Waterjet cutting machines have many advantages. It does not create a heat-affected zone, that is, the area around the material during cutting is not affected by thermal deformation or discoloration. Water knife cutting machine can cut a variety of hardness and thickness of materials, including metal, stone, rubber and so on. Third, because there is no chemical reaction and combustion in the water knife cutting process, no harmful gases are produced, and the environmental protection is good.

Water knife cutting machines use the impact and speed of high-pressure water flow to cut various materials. The high-speed water jet formed through the nozzle can precisely cut the material into the desired shape and size. The principle of water knife cutting machine is simple and efficient, and it has been widely used in industry and manufacturing.
