It is reasonable to know how to maintain the different working conditions. We have a forum card friend to post that the DeLong F3000 dump truck has an unstable speed. In the process of introducing the vehicle maintenance, we learned that the car was in September 2012. Purchased, driving 80,000 kilometers, the oil machine filter changed every 10,000 kilometers, the diesel filter was replaced at the end of last year, and the air filter was changed this year. So as a dump truck, is such a maintenance cycle correct? Below we briefly introduce the maintenance of Weichai http://Lanqing series engine as an example.
Lan Qing, the English word land king transliteration, taken the meaning: the king of land. It is a large displacement diesel engine jointly developed by Weichai Power Co., Ltd. and domestic and foreign R&D institutions. Since its launch in 2005, the Blue Engine has been recognized by the market for its energy saving, environmental protection and high efficiency. At present, the Weichai Lanqing series engines mainly based on WP10 and WP12 have a high market share in the heavy truck market.
â— Different maintenance conditions have different maintenance intervals
We all know that reasonable maintenance can effectively improve the service life of diesel engines, reduce the failure rate and reduce the cost of use. The standard of maintenance and maintenance of many card friends is often maintained according to the single standard of mileage. However, we know that the working conditions and working environment of the vehicle are very different, such as the cold or hot weather, the high dust content of the environment, the short-distance engineering transportation, the medium-long distance overload transportation and the long-distance standard-load transportation. The maintenance cycle of the vehicle is different in different environments.
So how to make the maintenance of the vehicle more reasonable, we can refer to the maintenance schedule of the Weichai Lanqing series engine, which gives different maintenance intervals according to different models and load conditions.
| Model | Road truck | Off-highway trucks (including cement mixers) | Construction machinery | ||
| Load situation | ≤ standard load | >standard load | ≤ standard load | >standard load | |
| First maintenance | Driving 3000km or 50 hours | Driving 3000km or 50 hours | Driving 3000km or 50 hours | ||
| Routine maintenance | 40,000 km or 500 hours | 30,000 km or 400 hours | 20000 km or 300 hours | 15,000 km or 200 hours | 10,000 kilometers or 200 hours |
Note: 1. The above maintenance mileage or time period is subject to availability. 2. Routine maintenance intervals should be appropriately shortened under severe conditions. | |||||

First maintenance: change the oil and oil filter, do not replace the diesel coarse filter, fine filter; adjust the valve clearance, check the belt tightness, check the tightness of each pipe clamp, check the tightness of the bolt, tighten the cylinder head bolt, check the core filter Water level. If no water removal filter is installed, it is recommended to install.
Routine maintenance: change the oil, oil filter, diesel crude filter, diesel fine filter, water removal filter.
â— Maintenance according to time, neglecting the harsh working conditions, shortening the cycle
We know that many construction machines on many construction sites are equipped with a working hour meter to calculate their working hours, and many maintenance and maintenance cycles are also used as an example. However, the dump trucks that are also operating on the construction site, especially the dump trucks with short pits and pans, have a large working intensity on the one hand, and the vehicles have high load, large load and low speed operation, and may even work day and night, but the mileage is not much. At this time, it is very unreasonable to carry out maintenance according to the driving mileage. It is relatively reasonable to carry out maintenance according to the working hours of the vehicle.
At the same time, the dust on the construction site is relatively large, which is a big test for air filtration with vehicles. In addition, many construction sites are equipped with their own on-site refueling vehicles in order to facilitate the refueling of vehicles. At the same time, in order to reduce costs, these oils are generally cheaper and the quality is uneven. Under such bad working conditions, in order to ensure the vehicle Reliable operation, the maintenance cycle needs to be shortened accordingly.
â— Compilation:
Reasonable maintenance can effectively improve the service life of the engine, reduce the failure rate and reduce the cost of use. The paper only introduces the maintenance and maintenance cycle of the Weichai Blue Engine series. Other models can refer to the vehicle and engine maintenance manual, and according to their own The actual use conditions are reasonable to adjust your maintenance cycle. (Text / Figure Yang Jianwei)
