Problems easy to occur in the use of hot water pressure washer
, we make a summary of this
1.Please check if the motor running direction is correct when starting up;
Inspection method: Put it on the exhaust vent of the vortex furnace with your hand and feel that it is discharged from the wind, that is correct; if there is no wind or feel that the air is drawn in, it means that the power supply is in the wrong direction, please replace the power cord sequence
Faults and causes caused by misconnection:
1) Cannot ignite: Because the motor shaft is connected with a blower impeller and a circulating oil pump.
2) No fuel injection: The circulating oil pump is reversed, the fuel cannot run normally, and the oil cannot be sucked; the long-term reversed rotation causes the machine to become non-lubricated and damage the ring;
2. Is the water in and out of the equipment normal? Is there any water shortage or leakage?
Inspection method: observe whether the water flow is sufficient; stop the water immediately and check the water source for water leakage or insufficient water supply;
Failures and causes caused by water shortage or insufficient water supply and leakage:
1) Damaged sealing ring: When the machine is running, the plunger can go back and forth 1000-2000 times per minute in the pump. Water plays a good role in auxiliary lubrication. Without water, each component is extremely easy to wear;
2) Water leakage in the pump body: After the sealing ring is worn, the pump leaks water; the pressure is reduced, and the machine cannot be shut down automatically.
3) Water leakage at the water outlet (high-pressure pipe, gun rod, and joints between them), which can't stop the gun when it is turned off;
3.After use, please depressurize the gun rod and high-pressure pipe;
Note: After using the machine, turn off the main power, hold the water release switch on the handle of the gun, and release the remaining high-pressure water; if there is no pressure relief habit for a long time, switch the thimble, high-pressure pipe and sealed valves everywhere.
Being under high pressure for a long time will greatly reduce the service life;
4. Please ensure that the fuel is free from pollution and impurities. Although there are several oil filtering devices in the equipment, excessive impurities will cause blockage and damage to the fuel injection pipeline and injectors.
5.Please use tap water as much as possible; there are two reasons: 1) the tap water is clean enough, the chemical composition is not complicated, the impurities are less, the corrosion, blockage and wear of the plunger pump are reduced, and the service life of the equipment is increased; 2) the tap water itself has pressure, It can assist in pressing water into the plunger pump to reduce the working pressure of the plunger pump, although the plunger pump of the hot water high pressure washer has a self-priming function;
The above are the problems that are easy to appear in the use of hot water high pressure cleaners today. We have summarized all of them and hope to help everyone in using this equipment in the future.
