Sewage suction truck common fault

If you do not pay attention to maintenance, you will often find this or that problem. The following Xiagong Chusheng (Hubei) Special Purpose Vehicle Manufacturing Co., Ltd. lists for you a number of problems often encountered by sewage bus drivers. Corresponding sewage vehicle problems to make some practical answers, hoping to let the friends to open sewage suction car less trouble!

The engine is not on fire when the suction truck starts

Reason: The start of the engine is driven by the electric current of the battery to promote the ignition of the spark plug. There may be two reasons why the engine suddenly fails to fire. First, it may be caused by the rust of the battery or the leakage of the battery. The second is the spark plug of the engine in the rainy weather. Caused by dampness.

Maintenance method: Check the battery liquid in the battery every two months. The liquid level is considered to be suitable if it is located between two upper and lower reticle lines during observation. At the same time, the liquid level difference in each tank should also be checked. If the liquid level is insufficient, you can unscrew the lid on the battery and pour distilled water to make up for the liquid level. Then also check the battery terminals, use the iron brush to remove the dirt on the terminal. If the wiring clamps are heavily insulted, you can use sandpaper to rub along the inner wall to remove dirt. If the spark plug gets wet, take it out and bake it with a lighter to evaporate the water as quickly as possible.

Sewage car exhaust noise increases exhaust emissions increase excessive

Reason: This reason may be due to the oxidation of the engine exhaust gas at high temperatures, resulting in leakage of the exhaust system.

Maintenance method: Regularly inspect the exhaust system's pipeline, interface (especially silencer, etc.) is corroded by the exhaust gas, the interface pad has not been damaged. If you find that the exhaust system leaks, you should promptly go to the 4S shop to repair or replace the leaked parts. Checking once a year will not only ensure the normal operation of the exhaust system, but more importantly, reduce the pollution of harmful substances in the exhaust gas to the environment.

Sewage truck fuel consumption increased inexplicably

Cause: There are many reasons for the increase in fuel consumption. But the most common and easily overlooked by owners is the inspection of tire pressure. Insufficient tire pressure not only leads to increased running resistance, resulting in increased fuel consumption, but also affects the service life of the tire.

Maintenance method: When driving, pay more attention to whether each tire has gas, and regularly check the tire pressure. Of course, remember not to forget the inspection of spare tires, so as to avoid the urgent need to replace the tires, only to find that the spare tire has no gas. When the temperature is high, the tire pressure will be higher than usual, so it is more accurate to measure the tire pressure in a cold or cool place. From time to time, every 10,000 km of tires must be interchanged, avoiding too much difference in front and rear wear. If it is necessary to replace tires that are heavily worn, it is best to replace them with two or four, and tires with the same pattern can be interchanged before and after. In addition, lined tires help save fuel.

Sludge truck engine performance decreased significantly with increased fuel consumption

Cause: This is probably due to problems such as the lack of replacement of engine oil, oil filter, air filter, and fuel filter caused by insufficient fuel combustion and increased engine carbon deposition.

Maintenance method: Oil and oil filter should be replaced every 5,000 kilometers. Air filters and fuel filters need to be replaced every 10,000 kilometers. Otherwise, impurities in air, fuel, and oil will be lost. Causes parts to wear out and block the oil circuit, thus affecting the normal operation of the engine.

Suction pump damage

Cause: Unreasonable behavior during refueling may cause damage to the pump.

Maintenance methods: When the car owner refuels the car, try not to wait for the fuel warning light to turn on and refuel. This will shorten the service life of the pump. Too little oil or exhausted fuel may burn the pump. If you are driving in the urban area and you are more convenient to add fuel, you do not need to top up once because it may cause oil buoys, sensor malfunction, oil gauge distortion, and increased fuel consumption. Therefore, it is recommended that owners refuel when their fuel consumption is almost the same.

Suction truck battery instability

Cause: Unusual changes in electrolyte can affect battery performance and reliability.

Maintenance method: driving in summer, the battery will appear overcharge phenomenon, the electrolyte evaporates quickly, the polar plate is easy to damage. Therefore, it is necessary to constantly check the liquid level of the battery and the specific gravity of the electrolyte (the specific gravity of the electrolyte should be smaller than in the winter). Always add distilled water to the battery. Avoid discharging the battery completely in winter and pay attention to whether the electrolyte is frozen.

Sewage suction wiper scraping glass is not effective

Cause: The wiper blade is broken and can cause scratching.

Maintenance methods: First of all, owners need to correct the bad habits of dry scratch, it is best to spray water and then open the wiper, which is conducive to protecting the wiper blade. Second, the wipers sometimes make a rattling noise. If the wipers are complete, then the owner should go to the 4S shop to correct the wiper angle. Finally, if the vehicle is parked for a long period of time, the owner can find small things such as foam strips or wooden sticks and place it under a wiper to separate the wiper blade from the windshield, which can extend the life of the wiper.
