Operating steps of high pressure washer
1. Preparation before starting
Before starting, check whether the screws and nuts of all parts of the washing machine are loose. The 30 # or 40 # oil has been added to the pump eccentric shaft box, and the oil level needs to be checked (it is beneficial to spill over the oil mirror).
2.Inlet pipe connection
Put the water inlet hose on the water inlet connector of the pump body, then put on the throat card, and tighten the screws on the throat card to ensure that the connection is firm and airtight. Then put the other end on the tap or put it into the water supply tank according to the condition of the water source (the water inlet must be completely immersed in water), and the water inlet pipe requires a filter to prevent the high-pressure pump from being damaged by the impurities.
3.Outlet pipe connection
Connect the end of the high-pressure hose to the quick-connect joint on the outlet of the machine; connect the other end to the threaded joint on the trigger valve of the spray gun. Refer to the structure diagram for the connection method (connection method for quick-change joints: just push the knurled sleeve backwards, and then push the joints inward). Note: The high-pressure water pipe cannot be kinked, and it should be stretched and straightened as much as possible.
First of all, make sure that the power supply voltage is consistent with the requirements of the label. The connection of the fixed power supply used by the high-pressure cleaner should be performed by professionals and should meet the requirements of GB / T16895. If an extension power cord is used, the plug and socket should be waterproof. When connecting the socket, the switch of the washing machine must be set to the "off" position.
5, replaceable nozzle
High-pressure cleaner spraying qiang can adjust the spraying water flow by replacing the spray head. The short qiang head is a round hole beam flow, and the long qiang rod is a fan-shaped water flow.
①Beam-shaped water flow with round holes-This nozzle can produce a beam-like powerful jet for the surface with particularly serious dirt. Such as agricultural machinery, construction machinery, etc.
②Fan-shaped water flow——The spray head produces a fan-shaped jet with a large scattering angle and a small impact on the object to be cleaned. It can be used to clean a large area of dirt surfaces, such as cars, buses, trucks, tractors and other various vehicles. , Ships; vegetable and food processing plants, hotel kitchens; baths, swimming pools; barns and livestock fences, exterior wall cleaning of high-rise buildings, etc.
6.Start the machine
Check that the water inlet pipe and the high-pressure water outlet pipe are connected reliably, the power socket is connected, you can plug in the power, pull the trigger of the spray gun, and the high-pressure water can be ejected after the air in the standby tool is drained. When using for the first time, the air discharge is slow. You can remove the high-pressure water pipe first, and shut down when there is no water at the water outlet, and then connect the high-pressure pipe to the quick connector, and then use it again.
7. If water is supplied to the pump from the water tank, the pump should be filled with water from the water inlet pipe at the same time when the pump is turned on, and the trigger of the spray gun is half-pull to make the air in the pipeline exhaust. After the pump works normally, set the water inlet pipe Just put it in the water tank. At this time, a filter must be installed at the inlet of the water pipe to prevent foreign matter from being sucked in.
8. When cleaning with a bundle of powerful jets, the distance between the nozzle and the surface to be cleaned should not be too close, so as to avoid damage to the object being cleaned due to excessive pressure. When cleaning fragile surfaces, go from near to close and carefully observe the changes.
9. When the intermittent time is too long (more than ten minutes), the power switch should be turned off, and the spray gun valve should be opened to make the water spray pipe and spray gun in a non-pressure state, so as to avoid the heat generated by the water circulating in the pump body when the pump is unloaded to damage the pump Inside parts.
10. The working pressure of the cleaning pump has been adjusted to 6Mpa when leaving the factory. Users should not increase the pressure arbitrarily to avoid damage to the washing machine due to changes in working conditions. If you find that the pressure is insufficient, you can follow the tenth fault analysis and troubleshooting.
11. When in use, water leaks from the drain hole connected to the sandwich copper of the pump body, which does not affect the use, and it is normal operation.
12. Under normal circumstances, first turn off the power switch, unplug the power plug, turn off the water source (when tap water is supplied), trigger the spray gun to release the residual pressure in the pump.
13. When the machine is transferred, the high-pressure water hose can be pulled out through the quick-change joint to move it.
14. The nozzle and trigger of the spray gun are related to the performance of the washing machine. When not in use, it should be properly placed to avoid injury and use.
15. Use after the machine is on hold: Because the starting torque of a single-phase motor is small, if you press the start switch, the motor will make a buzzing sound (the motor does not rotate), you should immediately press the stop button and repeat it two or three times, the motor can run ; If the motor still fails to start, remove the motor fan cover, turn the fan by hand for two or three weeks, and then start the motor. After starting successfully, reinstall the fan cover in the off state.
The above is all about today ’s detailed explanation of the operating steps of the high pressure washer in accordance with the charter. I hope that it will be helpful to everyone in using this equipment in the future.
