What are the measures to prevent the oil leakage of the cleaning suction truck?
In the application of many special purpose vehicles, common faults of oil leakage usually occur, such as cleaning and sucking vehicles. Cooperating with the manufacturer of the suction truck, it said that these problems immediately endanger the technical characteristics of the cleaning suction truck, cause the consumption of lubricating grease, gasoline and diesel, consume the driving force, endanger the clean and tidy appearance of the truck, and lead to air pollution. Then, we should pay more attention to the application. Next, we need to cooperate with Huaian city to clean and absorb the dirty car. According to our own work experience, we should teach you several aspects about the countermeasures to prevent the oil leakage of the cleaning and absorbing the dirty car
Measures to prevent oil leakage of cleaning and suction truck
１、Pay great attention to the effect of gasket. The gasket in the static position of the car (such as each close connection inner hole, each bearing end cover, cover shell, cover pad, and the back cover plate of the wire cutting enamel on the plan) plays a role of leakage sealing. If the raw materials, manufacturing quality and installation do not meet the technical standards, it can not have the sealing and leakage supplement effect, and even produce safety accidents. For example, the engine oil pan or cylinder block head will not be easily rammed due to the large area of the engine, which leads to oil leakage.
２、All kinds of nuts in the car should be tightened according to the specified torque. Cooperating with the sewage truck manufacturer, it is said that if the pressure is too loose, the gasket will also leak; If it is too tight, the metal material around the wire hole will protrude or the wire mouth will slip, causing oil leakage. In addition, if the oil drain plug of the engine oil pan is not tightened or loosened, it is very easy for the engine oil to flow out, which will lead to the safety accident of engine damage.
３、Replace the invalid oil seal immediately. Many moving positions (such as oil seal and O-ring) in the car will throw oil due to improper installation, different center between motor shaft and oil seal knife edge, and deflection. Some oil seals will lose their ductility due to the embrittlement of vulcanized rubber after being used for a long time. We cooperated with the manufacturer of the sewage truck to remind everyone that if they find water leakage, they should be upgraded immediately.
４、Prevent the product and valve from blocking. Thus, the temperature in the aluminum panel will rise, the gas will fill all the indoor space and cannot be discharged, the working pressure in the box will rise, and the time of grease lifting and replacement cycle will be reduced. After the software of diesel engine ventilation system is blocked, the friction resistance of fitness exercise of piston rod is increased, and the fuel consumption is increased. Because of the effect of the standard air pressure difference inside and outside the aluminum panel, it usually causes oil leakage at the sealing defect. Therefore, it is necessary to carry out regular maintenance, transportation and cleaning for the cleaning and suction truck.
５、Properly handle all kinds of high pressure hose seals. The coupling nut is often disassembled, so it is easy to slip and break, which will cause oil leakage. The union nut is disassembled and replaced, and the spherical seal is processed by grinding method, so that the nut is clamped and the seal is processed.
６、Prevent the rim from spilling oil. Too much grease in hub bearing and cavity, or improper installation of oil seal, poor quality and embrittlement are invalid; The wheel rim temperature is often too high due to the braking system; The looseness of the transmission shaft nut will cause the rim to throw oil. Therefore, it is necessary to use the internal cavity moistening method (i.e. appropriate moistening) to transport the ventilation port.
