Owners and operators of construction machinery deal with equipment all the year round, and equipment is their “brother”! Therefore, it is indispensable to provide good protection for “brothers”. As the heart of engineering machinery, engine wear is inevitable during use, but some wear can be avoided through scientific verification.
The cylinder is the main wear part of the engine. Excessive cylinder wear will result in a significant decrease in the power of the equipment, resulting in an increase in equipment oil consumption, and affecting the lubrication effect of the entire system of the engine. Even the engine needs to be overhauled after the cylinder wear is too large, which is expensive and the owner suffers economic losses.
These tips to reduce engine wear, you must know!
1. The temperature in winter is low. After the engine is started, it should be preheated for 1-2 minutes to make the lubricating oil reach the lubrication points. After all parts are fully lubricated, start to start. Be careful not to increase the speed and start when the car is cold. Bouncing the throttle at the beginning to increase the speed will increase the dry friction between the cylinder and the piston and increase the wear of the cylinder. Do not idle for too long, too long will cause carbon accumulation in the cylinder and increase the wear of the inner wall of the cylinder bore.
2. Another main reason for a hot car is that after a long period of parking when the car is resting, 90% of the engine oil in the engine flows back into the lower oil shell of the engine, and only a small part of the oil remains in the oil passage. Therefore, after ignition, the upper half of the engine is in a state of lack of lubrication, and the engine will not send the oil pressure to the various parts of the engine that need lubrication due to the operation of the oil pump after 30 seconds of operation.
3. During operation, the engine coolant should be kept in the normal temperature range of 80～96℃. The temperature is too low or too high, it will cause damage to the cylinder.
4. Strengthen maintenance, clean the air filter in time, and prohibit driving with the air filter removed. This is mainly to prevent dust particles from entering the cylinder with the air, causing wear on the inner wall of the cylinder bore.
The engine is the heart of engineering machinery. Only by protecting the heart can your equipment provide better service. Pay attention to the above problems and adopt scientific and effective methods to reduce engine wear and extend engine life, so that the equipment provides you with greater value.
