The cleaning process of the high-pressure cleaning machine includes four basic elements, these four elements are respectively: pollutant, medium, matrix and cleaning force. However, we are concerned about what is the high pressure water jet cleaning effect of —— high pressure cleaning machine? Because it directly affects our work efficiency. So what directly affects the cleaning effect of the high-pressure water jet? In fact, the cleaning effect is the force of —— on the cleaned object. In addition, the factors that affect the cleaning effect include the following aspects, which are:
(1) The hydraulic parameters also have a huge impact on the cleaning effect.
(2) The choice of the working parameters of the high pressure water jet played by the high pressure cleaning machine directly affects the cleaning effect.
(3) the material properties of the cleaned object also affect the effect of cleaning.
(4) the degree of grinding and cavitation also has a significant effect on the cleaning effect.
(5) the cleaning effect of the high pressure water jet itself, the speed obtained through the nozzle, the impact force of the kinetic energy conversion on the cleaned object, and the sum of the combined force generated by the interface flow of the fluid on the cleaned object, etc.
From this point of view, in fact, there are many factors affecting the cleaning effect of the high-pressure cleaning machine, but this does not directly affect the possibility of improving our work efficiency. As long as we can grasp the crux of the problem, then our cleaning effect is bound to improve a lot.
During the actual operation of the high pressure washer, always maintain hands and soles of the feet, not directly contact these cleaning nozzles, and always check all electrical connections, check all internal inside and check their hoses. Is there a crack or a leak? If the gun is not used, these devices must be placed in * * * locked state.
What should I pay attention to when using a high-pressure cleaning machine?
Before use, you should check the pump. If not, you should add oil before use. Before use in winter, check whether the machine is frozen. If there is ice, the ice will melt before turning it on; after the use, drain the water in the pump and put the machine in the heated room to prevent the machine from freezing.
1. When using the equipment, the power supply shall be equipped with leakage protection switch and grounded * * *, and must match the socket with good grounding wire; the input (input) voltage should ensure its stability, too low or too high voltage will cause damage to the equipment. In general, the voltage of single power should be between 220V-240V, and three power should be between 380V-400V.
2. Input (input) power line diameter should not be too thin, not too long. General cleaning equipment motor power is large, for the capacitor starting motor, starting current is large. Therefore, the selection of cable wire diameter section should not be less than 4 square, the length of the wire should not be longer than 25 meters. The wire shall be thick to 6 square meters; otherwise the electricity will cause heat, not start, and even burn out.
3. The high pressure pipe is strictly prohibited to be rolled over by heavy objects such as vehicles, so as to avoid the bursting of the high pressure rubber pipe.
4. During the use of the machine, it is strictly prohibited to send high pressure water to the position of the cooling fan, to prevent the leakage danger caused by the motor water.
5. ① In addition to paying attention to the power voltage problem but also consider the diesel * * * to choose good, and does not contain impurities, not allowed to mix water.②, diesel label should be selected according to the temperature change of the weather. The basic formula is as follows: the current ambient temperature is subtracted from 15. For example, when the current ambient temperature is zero, the selected diesel label is minus 15 and minus 25.③ Water quality should be clean, as far as possible without impurities, and the water filter screen should be cleaned regularly. Every time the machine is used, the water in the pump should be discharged, and put the machine in the heated room, in case the cold weather will freeze the machine.
High pressure cleaning machine nozzle is crucial for the discharge of high pressure water, but we will find that the high pressure cleaning machine nozzle wear more problems. Damaged nozzle will disperse the high pressure water jet, which affects performance. So, what is the cause of the wear of the high-pressure cleaning machine nozzle?
1. High temperature intrusion on the nozzle: if the high pressure nozzle runs for a long time at high temperature or abnormal temperature, the nozzle may be damaged due to the softening of the material.
2. Corrosion damage of nozzle: when we use chemical materials to spray and clean objects, these chemicals usually cause corrosive damage to high pressure nozzle material, thus in * * * hidden danger.
3. Nozzle hazard: the continuous accumulation of chemicals and impurities inside and outside the high-pressure nozzle will cause the nozzle blockage. This usually affects the spray shape of the nozzle, in turn affecting the working pressure of the high pressure washer.
jetting machine
4. Accidental damage of the nozzle: For * * * consideration, although the opening of the high-pressure nozzle is usually designed as concave, if we cannot use it correctly and cannot timely maintenance and maintenance, the bias structure of the fan nozzle is very easy to suffer.damaged.
5. Corrosion damage of nozzle: the possibility of high pressure nozzle corrosion mainly depends on the working pressure of high pressure washer, the type of chemical material used, the hardness of liquid and its flow rate. In addition, the particulate impurities in the liquid can also corrode the nozzles. When the high pressure water jet flows through the metal surface of the nozzle hole, it will cause corrosion damage to the nozzle hole, which usually causes the pressure reduction and the spraying state becomes irregular.
When selecting the cleaning fluid, the following three factors should be considered.
Cleaning efficiency: Always test when selecting the cleaning solvent of * * *. If ultrasound is introduced during the existing cleaning process, it usually does not need to replace the solvent used;
Simple operation: the liquid used should be non-toxic, easy to operate, long service life;
Cost: The cost of using cheap cleaning solvents is not low. Considering the cleaning efficiency and * * * performance of the solvent, the amount of clean solvent and the high utilization rate of the workpiece. Of course, the selected cleaning solvent achieves the cleaning effect and should be compatible with the material to be cleaned. Water is a common cleaning solution, so the system using a water-based solution is easy to operate, low cost and widely used. However, many solvents are available for certain materials and soils that are not suitable for aqueous solutions.
Another consideration of the high pressure washer is the design of the upper and lower materials of the cleaning member or the tool for placing the cleaning member. When the cleaning unit is located in the ultrasonic cleaning tank, the cleaning unit and the cleaning basket shall not contact the bottom of the tank. The total cross-sectional area of the cleaning part should not exceed 70% of the ultrasonic bath cross-sectional area. Rubber and non-rigid plastics absorb ultrasonic energy, and therefore care should be taken when using these materials. Special attention should also be paid to the insulation and cleaning components. Even if the good ultrasonic cleaning system is much less efficient, the tool basket design is not appropriate, or the workpiece is too heavy. If the mesh is above 50 mesh, any material exhibits the physical properties of the ultrasound and reflects it. When the mesh is greater than 1 / 4 inch. Hgs, shelves and beakers can be used to support the cleaning components.
The high pressure spray gun of the high pressure cleaning machine is the core component of the cleaning machine and the main tool of direct crushing scale. The high pressure cleaning machine is composed of nozzle, nozzle, spray gun, spray rod and connecting joint and other components.
Working principle of the spray gun:
Spray gun is a more frequent action of a component, is a ball valve with a trigger operation as the core of the simple machinery. The nozzle valve bead is kept in the closed position or in the forward position under the action of water flow. Or close the passage of the water through the gun to the nozzle. When pulling the trigger, it pushes a piston against the bead, forcing the bead out of the seat to open the flow to the nozzle. When the trigger is released, the beads return to the valve seat and close the channel under the action of the spring, the gun shall be convenient to the operator. In general, front-in guns are used for low-pressure equipment and are cheaper. The rear-in guns are more convenient, they rarely last, and the hoses do not block the operator.
Common fault of spray gun:
High pressure cleaning machine does not water if the water, the air in the high pressure pump, repeatedly switch the air in the high pressure pump can be discharged water, or connected to the tap water after the self-imbibited water start equipment. If the tap water is connected, it may be that the high and low pressure valves in the high pressure pump are connected after placement for a long time, and the air compressor is injected to the equipment by the inlet. When the spray gun is ejected and connected to the tap water, the equipment can be started.
Working principle of the nozzle:
Nozzles affect pressure and efficiency, and a small injection area means greater pressure, which is why rotating sprinklers are becoming more popular. They don't actually increase the pressure, but they use zero injection angles in a moving way to cover larger areas faster than you use zero angles.
Common nozzle fault:
If the porous injection nozzle appears 1 or 2 holes are blocked, the nozzle or the nozzle injection force and the reaction force will tilt in one direction or to the rear, and the object will swing the dagger quickly, causing great damage to the operator. Therefore, it is necessary to test it with low pressure water before firing, and confirm that there are no holes to work.
Operating principle of the gun barrel:
Usually 1 / 8 or 1 / 4 inch diameter, there shall be sufficient length to prevent the operator from placing the hand in front of the nozzle at high pressure. The end allows you to get an angle, and the length means how far you are from being cleaned without being splashed. Cleaning efficiency may decrease with your distance from the cleaned object. For example, 12 inches will be half the 6 inch pressure.
Common barrel faults:
The nozzle and spray rod or high pressure hose are usually threaded or quick connection, if the connection is not strong, the nozzle will fall off, then the high pressure hose will be disorderly swing, hurt the surrounding personnel.
