Water hydro jetting machines are high-pressure water jet machines that can be used for industrial cleaning, surface preparation, and cutting. There are two types of water jet cutting machines: pure water jet cutting machines and abrasive water jet cutting machines. The former is for soft materials like rubber, foam, and gasket materials, while the latter is for hard materials like metal, ceramic, stone, glass, and composite materials. The main goal of a water jet cutting machine is to provide a precise, clean, and versatile way to cut a wide range of materials without heat-affected zones.
Another common type of water jet machine is the surface cleaning machine, which can be divided into a high-pressure water jet cleaner and an automatic water jet cleaner. The high-pressure water jet cleaner is a machine that uses a high-pressure water jet to remove dirt and other impurities from surfaces and objects. It can reach pressures up to 3000-4000 bars and is used for industrial cleaning, paint removal, and surface preparation, among others. The automatic water jet cleaner is a machine that features an automated system that controls the movement of the water jet nozzle and the workpiece. This machine is ideal for high-precision cleaning applications that require consistent results and automation.
Many industrial processes require hot water, which is why hot water jet machines are also common. The hot water jet machine uses a high-pressure water jet to cut, clean, or remove material while using hot water. These machines can reach pressures of up to 4000 bars and are used in a wide range of applications, such as industrial cleaning, degreasing, and paint removal. In some cases, the hot water jet machine can be used for cutting hard materials like metals and ceramics.
Steam jet machines are also a common type of water jet machine. They use high-pressure steam jets for cleaning, cutting, and other applications. Typically, the steam jet machine is used in cleaning, sterilizing, and degreasing, among others. The steam is under high pressure and temperature, which allows it to remove contaminants and kill bacteria and other microorganisms.
When purchasing a water hydro jetting machine, it is essential to consider its specifications as well as the recommended maintenance practices. Here is a guide on the specifications and maintenance of the water jet machine.
Pressure: The pressure of a water jet is usually measured in pounds per square inch (PSI). It varies depending on the type of machine and its application. Most water jets have a pressure of between 20,000 and 90,000 PSI. Higher pressure machines can cut through harder materials and also do a better job of cleaning and surface preparation.
Flow rate: This is the volume of water that the machine can deliver per minute. It is typically measured in gallons per minute (GPM). Flow rate works together with pressure to determine the cutting speed and overall performance of the water jetter. The GPM of water jets can also vary depending on the type of pump used. For instance, low-pressure water jets may have a flow rate of 0.5 to 1 GPM, while high-pressure water jets can deliver anywhere from 1 to 8 GPM.
Power: The power of a water jet machine is typically measured in kilowatts (kW). It is used to determine its cutting capacity. Low-power water jets may have a power of between 30kW to 50kW, while high-power water jets may have a power of 50kW and above.
Control system: Water jets are usually equipped with a control system that regulates the water pressure, flow rate, nozzle movement, and other operational parameters. The control system may also include software for programming the cutting paths and shapes. Some advanced water jets have a CNC (Computer Numerical Control) system that allows for high-precision, automated control of the machine.
Regular cleaning: One of the essential maintenance tips for a water jet machine is to ensure it is regularly cleaned. This helps to remove any debris, dirt, or abrasive residue that may have accumulated during the operation. The cleaning process also helps to safeguard the machine's internal components from damage and wear.
Lubrication: It is also essential to lubricate the critical components of the water jet machine. This includes the pump, cutting head, and motion system. Lubrication helps to reduce friction and ensure smooth operation of the machine. The lubrication process also helps to prevent premature wear and tear of the components.
Inspecting and replacing parts: Users should inspect the critical parts of the water jet machine regularly. This includes the cutting nozzle, seals, and hoses. Check for any signs of damage, wear, or leaks. In case of any issues, it is essential to replace the damaged parts immediately. Regular inspection and replacement of parts help to enhance the machine's performance and safety.
Proper storage: Users should ensure that the water jet machine is stored in a clean and dry environment when not in use. Proper storage helps to protect the machine from environmental damage and corrosion.
