Equipment Introduction
Megajet high pressure cleaning machine is water as the working medium, usually, the power drive pump through the water to complete a suction, discharge process, the ordinary water into high low flow rate of water, and then transported to the high pressure pipeline, so that it with a certain amount of energy to reach the high pressure nozzle. The aperture of the high pressure nozzle is much smaller than the diameter of the high pressure pipeline, so the water reaching the high pressure nozzle must be accelerated to pass through the nozzle. In this way, the nozzle can convert water at a high and low velocity into a low pressure and high velocity jet. The ejected high-pressure water jet tangentially or positively impacts the surface of the cleaned object, and constantly shocks the cleaned surface, making the dirt fall off. Therefore, the use of a high-pressure cleaning machine is a physical cleaning method.

The structure, function and working principle
Engine Parameter
Engine parameter and model number :WP10G360E341 Power:360 HP Max. Speed: : 2200 rpm
Three-pillar plug high pressure pump
The three-plunger high pressure pump uses the engine power to form the high pressure water output. The high-pressure pump is divided into two parts, the power end and the hydraulic end. The power end contains the components driving the pump, which is also known as the "crankcase" because it contains a crankshaft. The hydraulic end contains the components for use to determine the output pressure of the high-pressure pump, mainly including the pump head, combination valve, packing function, plunger, water seal, pressure regulating valve, pressure gauge, etc. Power end lubricating oil: 85W-90.
Filter
The filter is a series two-stage filtration, the first stage is no. 5 filter bag, the specification is 10 micron, the second stage is 4 core filter rod, 20 inches 5 or 1 micron, to provide clean water quality for the pump group. There is a pressure gauge above the filter to observe the water supply pressure of the equipment (the water pressure should be between 1bar and 3bar), and there is an air discharge outlet, where the operator should vent the air through the filter during startup.
Fuel Tank
The equipment is equipped with a fuel tank of about 560L, which ensures the continuous operation of the equipment for a long time. The oil tank is equipped with an oil level sensor.
Control Panel
The control panel has an emergency stop button, key switch and throttle control button. Real-time monitoring of engine speed, fuel oil volume, engine water temperature, engine oil pressure and other parameters
Battery
The equipment is equipped with a set of 24V maintenance-free batteries, and the main power supply switch is set on the circuit to open the main switch when starting the equipment and close the main switch when the equipment is disabled.
Booster Pump
The booster pump is used to provide sufficient water pressure for the equipment, connected to the engine by a belt at SPB-1340.
Regulating Valve
The pressure regulating valve is used to adjust the working pressure of the equipment in the range of 0~2800 bar. When working, the pressure is adjusted through the handle on the top of the valve body. The rear of the pressure regulating valve is used to export the excess flow. This return tube flows directly to a drain through a water pipe (it can also be connected to the inlet end of the equipment but not recommended).
Pressure Gage
The pressure gauge is used to display the system pressure in real time.
Safety explosion-proof Valve
Passive overpressure protection device, in the high pressure water jet equipment can prevent the system pressure is too high to protect the system safety, role, better guarantee the system and operation safety, when the system pressure over blasting pressure limit, blasting will implement blasting, so that the water flow from the explosion-proof base, makes the system pressure relief.
Turn off the equipment
1. Adjust the pressure regulating valve (if any) to reduce the system pressure;
2. Release the injection parts to keep the system in the pressure relief state;
3. Reduce the engine speed to idle speed;
4. Stop the engine after running for another 4-5 minutes, which enables the turbocharger of the engine to dissipate heat normally.
When the temperature displayed on the control panel decreases to about 80ºC, press the red stop button on the control panel to
turn off the engine;
5. Turn the key switch to the OFF position and turn off the main power switch.

At the end of use
★ pump group should gradually reduce the working pressure before stopping and run the empty load for 5-10 minutes before stopping.
★ When the ambient temperature is lower than 0ºC, if the pump leader is stopped, the residual water in the pump set and the pipeline must be drained to prevent freezing and components of the pump group.
★ Do not allow cleaning the parts of the pump unit with corrosive detergent.
★ In case of a major failure, the equipment operation should be stopped immediately.
