Engine maintenance knowledge of dump truck


1, grinding: that is, running-in


This is the basis for prolonging the service life. Both the new dump truck and the overhauled engine must be run in accordance with the rules before they can be put into normal operation.


2, net: oil net, water net, air net and body net


Diesel and gasoline are the main fuel of the engine, if diesel, gasoline is not pure, it will make the precise matching block wear and tear, increase the matching gap, cause oil leakage, drop oil, reduce the pressure of oil supply, increase the gap. If there is a lot of dust in the air, the wear of cylinder liner, piston and piston ring will be accelerated. If the cooling water is not pure, the cooling system will be blocked by scale. If the body appearance is not clean, the surface will be corroded and the service life will be shortened.


3, foot: oil foot, water foot, air foot


If the supply of diesel, gasoline and air is not timely or interrupted, there will be some problems such as difficulty in starting up, bad combustion, low power, and the engine of dump truck can not operate normally, etc. If the supply of oil is insufficient or interrupted. If the cooling water is insufficient, the engine temperature will be too high, the power will be decreased, the wear will be aggravated, and the service life will be reduced.


4.To inspect the fastening position regularly.


The bolts and nuts are easy to be loosened due to the impact of vibration and uneven load during the use of diesel and gasoline engines. The adjustment bolts of the dump truck should be checked. To avoid causing loosening and damage to the body accident.


5.Adjust: adjust the valve clearance and other details


The valve clearance, valve phase, fuel supply advance angle, injection pressure and ignition timing of diesel engine or gasoline engine should be checked and adjusted in time to ensure that the dump truck engine is always in good technical condition. In order to save fuel and prolong service life.


6. Use: use the engine correctly


Before driving, lubricating parts such as bearing bush should be lubricated. After starting, water temperature should reach 40 ℃ -50 ℃ before putting into operation. Long time overload or low speed operation is strictly prohibited. After stopping in winter, the water temperature should drop to 40 ℃ -50 ℃, except for the engine where cooling water rW has been injected with antifreeze. The maintenance work of engine should be done regularly. Keep the machine in good condition at all times. Observe, check, find fault and troubleshoot in time.
