United with the manufacturers of the suction truck to share with everyone the countermeasures to prevent 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. The United sewage truck manufacturer said that these problems immediately endanger the technical characteristics of the cleaning sewage truck, cause the consumption of lubricating grease, gasoline and diesel, consume the driving force, endanger the clean and tidy appearance of the vehicle, and lead to air pollution. Then, we need to pay more attention to the application. Now, we will work with the manufacturers of the suction truck to teach you how to prevent the oil leakage of the cleaning suction truck according to their own work experience.
Countermeasures to prevent oil leakage of sanitation garbage truck in sludge treatment
１、Attach great importance to the function of gasket. The gasket in the middle of the parts in the car's static position (such as each tight connection inner hole, each bearing end cover, cover shell, cover pad, flat wire enamel back cover plate, etc.) plays the role of leakage repair and sealing. If the raw materials, manufacturing quality and installation do not meet the technical standards, it can not have the effect of sealing leakage, and even produce safety accidents. For example, the engine oil pan or cylinder cover is not easy to tamp because of the large total area, which leads to oil leakage.
２、All kinds of nuts in the car should be tightened according to the specified torque. The manufacturer of the United suction truck said that if the pressure is too loose, the gasket will 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 engine oil pan is not tightened or loosened, it will easily lead to the outflow of engine oil, 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. The manufacturer of the United sewage truck reminds us that if we find water leakage, we should upgrade it 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 very easy to slide, break and loosen, which will cause oil leakage. Remove and replace the union nut, and use grinding method to deal with its spherical seal, so that the nut is clamped tightly to deal with the seal.
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 loose nut of the transmission shaft 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.
