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.
