Hot and hot seasons are gradually on the right track. This weather is not only a test for people, but also one of the sewage suction trucks. In such weather, to prevent the sudden appearance of spontaneous combustion, it should be the vehicle. The oil circuit, the line, the lubrication system, the tires, the cooling system, etc. must all be carefully inspected.
First, the oil system cleaning
Sewage sewers , when used cross-regionally when necessary, will have a mixture of different brands of vehicle oil. In the case of unmatched vehicles, the oil circuit will become very dirty. Under such use conditions, it is necessary to periodically clean the fuel-added system and maintain the cleanliness of the oil circuit, the fuel tank, and the fuel injector.
Second, the brake system inspection
Under high temperature conditions, the brake oil will be prone to expansion, which will reduce the effect of the brake on the suction truck. In addition, the vehicle will suffer from serious gravel environment for a long time and long-term braking will damage the brake pads. of. If the degree of wear of the brake pad is already beyond the factory's lower limit scale, or if there is an abnormal noise when the brake is depressed, then it directly indicates that the brake pad needs to be checked and replaced immediately. There is the need to pay attention to the adequacy of the brake fluid, it is necessary to select qualified brake fluid, and those fake and inferior brake fluids that are boiling too low are more likely to lose their effectiveness in the summer. Once a brake failure occurs, it will result in The consequences are not conceivable.
Third, air conditioning maintenance
For air conditioning maintenance of sewage suction trucks, the most important work is the need to work on sterilization and dust suction sewage truck air conditioning in the summer. In addition, when the sewer truck is driven at a relatively high temperature and lime causes some impurities or leaves blowing into the air-conditioning inlet system, unpleasant odor will occur when the air conditioner needs to be turned on. In the end, when alternating between the spring and summer seasons, the vehicle's air condensers and pipelines will be more prone to breeding maggots and germs. It will also become a breeding ground for these things, so you can just use this time to absorb the dirt. The car's air conditioning is a good cleaning.
Fourth, sewage suction circuit inspection
The temperature of the ignition coil will also become very high when the generator of the sewage suction truck is working. This will also make the insulating layer of the high-voltage ignition wire appear aging, cracking, softening, and ignition of high voltage electricity. Breaking through the insulation layer will cause short circuit, high voltage leakage, and even make the sewer truck appear spontaneous combustion. If the circuit is changed by oneself, it will cause the exposed power cord inside the vehicle. When it comes into contact with the metal material of the vehicle or other circuits, it will cause early short circuit or spark, which will also lead to spontaneous combustion of the suction truck.
Fifth, tire inspection
Because the summer temperatures are relatively high, the heat dissipation of the tires of the sewage suction truck will also be relatively slow, and the tire pressure will also become very high, making it easier to cause a puncture. Therefore, when the sewer truck is driven in a relatively high temperature environment, it is necessary to pay constant attention to the air pressure and temperature of the vehicle tire. In addition, due to the rain, the adhesion of the ground and tires will also be reduced due to rain, which is why the vehicles are slippery on rainy days. If the tire is worn out in rainy weather or if the tread pattern disappears, you need to replace it with a new one immediately. (Text / Sun Ni)
