After a long period of use, the engine of the cleaner will accumulate a layer of black dirt, which is composed of scales, dirt, dust and various oil stains. Don't underestimate these dirt. It also has a certain corrosiveness and is harmful to the plastic and rubber parts of the engine, which is known to us. After a long period of use, the engine of the dirt suction car will accumulate a layer of black dirt. These dirt is composed of dirt, mud, dust and various oil stains. Don't underestimate these dirt. It also has a certain corrosiveness, which is more harmful to the plastic and rubber parts of the engine. At the same time, these dirt will also hinder the heat dissipation of the engine of the dirt suction vehicle. So it is necessary to clean the dirt of the engine, so how to clean it?
First of all, the electrical components of the engine of the suction truck are waterproof and not afraid of water. Therefore, in many places, it is customary to wash the engine of the suction truck directly with a high-pressure water gun. Normally, repair factories will do so, and do not wash out the engine parts. But the following points should be paid attention to when cleaning high-pressure water gun:
1. Avoid washing with water when hot car is in condition
When the engine of the dung suction truck is cleaned at high temperature, the engine suddenly encounters cold, which may cause the cylinder body to deform and crack if it is serious. In addition, washing at high temperature will produce a large amount of water vapor, which may have an impact on the circuit.
2. Avoid engine safe box and driving computer as far as possible
Some suction trucks have tips on safety boxes in engine compartments to avoid high-pressure guns flushing here. Although there is waterproof treatment, general rain is no problem, but the pressure of high-pressure water gun is larger. Therefore, when cleaning the engine of the suction truck, we should try to avoid the area of the driving computer and the external safe box.
For "sensitive" areas, it is more appropriate to use wet cloth or soft brush to clean. If wet cloth and soft brush can not clean, you can use engine cleaning liquid. It is better to choose foam cleaner for bathing the engine of the suction car. Because foaming detergents stay long, they can effectively decompose oil molecules and some die molecules. Of course, this detergent can not be called terrific. After cleaning, it's better to rinse it again to prevent detergent from corroding the engine surface of the suction car.
