1, first check whether the nozzle is worn: find the nozzle position, directly tilt the nozzle with a screwdriver, connect a small hose below, directly remove the nozzle from the hose, carefully put the newly bought nozzle into the installation hole, and press it down directly to install the nozzle in place.
2. Water seal damage and spring damage may lead to insufficient pressure: carefully check all parts of the high-pressure cleaning machine and replace the damaged parts.
3. Insufficient water supply: check whether the water source pressure is sufficient. Some high-pressure cleaning machines have no self-priming function. Add a booster pump and find a water container to store water, so that water is enough.
4. Foreign matter entering the high-pressure cleaning machine causes equipment failure and blockage: clean the water supply filter, and replace it with a new one if it is damaged.
Characteristics of car washing machine
1, water system
Multi-liquid proportional shunt instrument is the product of foreign patented technology, which realizes the function of discharging double water with one shot. One is clear water, and the other is thermal decomposition of steam. Water vapor combination, convenient operation.
2. Billing system
The charging methods are inductive IC cards and slot machines.
The advantage of using inductive IC card is to avoid the phenomenon of poor contact when contact IC card is used for a long time, and the use environment is demanding. Inductive IC cards are less affected by the environment and have low failure rate.
3, coin-operated system
Coin-slot machine is a coin-slot machine integrating mass, volume and light perception, which has high safety, does not eat coins and has high sensitivity in identifying counterfeit money.
4. Chassis shell
The car washer is made of galvanized steel plate with the thickness of 1.5mm, which is safer and firmer. The machine does not rust, the paint is not easy to fall off, and it is corrosion-proof.
5, fault self-inspection system
When the machine fails during operation, the control system can self-check the machine, and convert the test results into corresponding fault codes, which are displayed on the control panel. Through the fault code comparison table in the manual, it is easy to find the cause of the fault and eliminate it.
