Maintenance techniques for sewage (manure) suction vehicles

1、 The importance of maintaining suction trucks.

The main function of a sewage suction truck is to suck up sewage and dirt, and its work content is very important. Without the help of a sewage suction truck, it is 

difficult to treat the sewage in the city. In order to maintain the normal working condition of the sewage suction truck for a long time, it is necessary to carry out 

reasonable maintenance on the sewage suction truck, so that it can work normally and extend its service life.

2、 Maintenance techniques for the air conditioning system of a suction truck.

The air conditioning system of a sewage truck is a device that cools, heats, exchanges, and purifies the air inside the cabin. Maintenance of air conditioning system; 

Regularly replacing the air conditioning filter can not only make the intake system cleaner, but also prevent a decrease in cooling capacity caused by clogged air 

conditioning filters. Regularly clean the air conditioning radiator, as the effectiveness of heat dissipation directly affects the cooling effect and fuel consumption. 

Regularly clean the air conditioning evaporator box, which is prone to mold growth and odor in dark and humid environments. Regularly inspect the air conditioning 

refrigerant (observation hole) for leaks. The use of air conditioning systems; Do not use the air conditioning immediately after starting the sewage absorbing car that 

has been parked under the scorching sun for a long time. First, open all the car windows and start the external circulation to dissipate the heat. After the temperature 

inside the cabin drops, close the windows and turn on the air conditioning. The lower the temperature of the air conditioner, the better. Adjust it to a temperature 

suitable for the human body (23 ° C energy-saving and environmentally friendly). Do not smoke in the car. Do not use the inner loop for a long time. Do not park and 

use air conditioning. Before stopping the sewage suction, turn off the air conditioning and then turn off the engine.

3、 Tips for maintaining a suction truck:

1. Regularly check the oil level of the engine. The suction truck is parked on a flat road surface, and then a vernier caliper is taken out to check the engine oil level. When the oil level is within the range of the markings (F) and (L), then its oil level value is considered normal; If its oil level is below the (L) level, it is necessary to add the corresponding type of engine oil to the engine, but it is reminded that the increase in oil level must be below the (F) level and cannot exceed it.

2. The fuel tank must be fully filled. Not filling up the fuel tank can cause the upper part of the fuel pump to be unable to cool down, resulting in heating and burning that requires replacement. Even a small fuel pump costs several hundred yuan.

3. Lubricating oil should be able to be replaced regularly. When the driving mileage of a sewage absorbing vehicle exceeds 5000 kilometers, it is necessary to change the lubricating oil. When choosing lubricating oil, some car owners will look at its price, but in fact, they need to choose the corresponding model of lubricating oil according to the actual needs of the engine, so that it can have a better effect.

4. The filter should also be replaced regularly. The filter on the engine can affect the quality and purpose of lubricating oil use, and it also needs to be replaced regularly.

5. The tire should not be overfilled and the tire pressure should be checked regularly. It is recommended to schedule tire pressure checks in the morning as much as possible. What are the maintenance techniques for sewage suction vehicles?

In addition to paying more attention to maintenance during daily use, owners of sewage suction vehicles should also be able to drive them to the corresponding maintenance points and have professional personnel use relevant techniques, accessories, etc. to complete specific maintenance work.
