There are some minor issues that need to be paid attention to in the process of using cold and hot water high-pressure cleaners, which are summarized as follows:
1. When operating the hot and Cold Water Pressure Washer: Always wear proper goggles, gloves and masks.
2. When the Spray Gun of the hot and cold water pressure washer is not used, the setting trigger must always be locked in a safe state.
3. Always check all the electrical connections of the hot and cold water pressure washer.
4. Frequently check all the hot and cold water high-pressure cleaner fluids.
5. Always keep hands and feet away from the cleaning nozzle.
6. Before disconnecting the hose, always release the pressure in the washing machine.
7. Always use low pressure to work as much as possible, but the pressure must be sufficient to complete the work.
8. Never start the equipment before turning on the water supply and allowing proper water to flow through the spray gun stem. Then connect the required cleaning nozzle to the spray gun stem
superior.
9. Always drain the water in the hose after each use.
How to extend the life of ceramic valve method
Ceramic valve initially used two-piece structure, in order to more rational structure of the valve into the now commonly used three-piece structure, this structure due to the dual seat, it also has a double seal characteristics. At the same time, the choice of ceramic ball valve attention to choose a ramp transition design of the valve, this valve can reduce the impact of the fluid. First, the cleaning pipe to extend the life Pipe in the welding slag, rust, solidified slag, wire, cloth, etc. in the throttle, circular arc polishing machine caused by blockage or stuck to the valve core fragmentation, often occurs in the new Put into operation system and overhaul after the initial investment. This is the most common failure. In this case, you must uninstall for cleaning, remove debris, such as the sealing surface is also damaged should be ground at the same time the bottom plug to open to wash away the debris, and the pipeline to be washed. Put into operation, let the control valve fully open, let the medium flow for a period of time and then into normal operation. Second, increase the opening work to extend the life of At the beginning of the use of ceramic valve to maximize the opening on the work, such as 80%. In this way, the initial impurities in the pipeline erosion, wear and other damage occurred in the spool outside the damaged part of the clearance of impurities in the pipeline, and then adjust the opening of the valve to the normal opening slightly larger , With the fluid damage to the spool, the flow increases, the arc polishing machine to reduce the corresponding opening, so constantly damaged, and gradually closed, so that the entire spool fully take advantage of until the valve core and sealing surface damage, can not be used until now . Third, increase the caliber to increase life expectancy CV value of the formula we calculate the correct CV to select the appropriate valve diameter (standard). In the case of the same flow, the smaller the diameter of the valve, the faster the fluid flow rate, the more aggressive the media will be to the spool and seal. Users are advised to be able to freely adjust the opening range, the appropriate increase in the diameter of the valve, which played a role in reducing wear. Fourth, to change the structure of circular arc polishing machine to improve life Ceramic valve initially used two-piece structure, in order to more rational structure of the valve into the now commonly used three-piece structure, this structure has a double valve seat, it also has Double sealed features. At the same time, the choice of ceramic ball valve attention to choose a ramp transition design of the valve, this valve can reduce the impact of the fluid. Fifth, transfer damage to improve life expectancy The place of serious damage transferred to the secondary location to protect the valve seat sealing surface and throttle face. Ceramic ball valve erosion is usually the most serious, the fastest fluid place is the fluid inlet of the lower part of the ceramic ball valve for the current three-piece structure, you can use the ball to the core, so a core can be used at the entrance of the four Times, the valve life to extend 4 times. The rational use of ceramic valves, to maximize its maintenance, to extend its service life, the use of ceramic valves is the primary problem.
