1. Correct starting and starting: When the engine is started cold, due to low temperature, high oil viscosity, and poor fluidity, the oil pump may not supply enough oil. At the same time, the oil on the original cylinder wall flows down along the cylinder wall after parking, so it does not receive the same good lubrication as during normal operation at the moment of starting, resulting in greatly increased wear on the cylinder wall during starting. Therefore, when starting for the first time, the engine should be allowed to idle for a few turns until the friction surface is lubricated before starting. After starting, the engine should run at idle speed to increase the temperature. It is strictly forbidden to bang the oil port. Wait until the oil temperature reaches 40 ℃ before starting; At the beginning, you should stick to low gear and drive for a certain distance in each gear in sequence until the oil temperature is normal before switching to normal driving.
2. Proper selection of lubricating oil: It is necessary to strictly select lubricating oil with the best viscosity value according to the season and engine performance requirements. Poor quality lubricating oil should not be purchased at will, and the quantity and quality of lubricating oil should be regularly checked and maintained.
3. Strengthen the maintenance of filters: Keeping the air filter, oil filter, and fuel filter in good working condition is crucial for reducing the wear of the 3NB1300C/1600 cylinder liner of the Lanshi pump. Strengthening the maintenance of the "three filters" is an important measure to prevent mechanical impurities from entering the cylinder, reduce cylinder wear, and extend the service life of the engine, especially in rural and windy areas. It is wrong for some drivers to not install air filters in order to save fuel.
4. Maintain the normal operating temperature of the engine: The normal operating temperature of the engine should be between 80-90 ℃. If the temperature is too low and good lubrication cannot be maintained, it will increase the wear of the cylinder wall. The water vapor inside the cylinder is prone to condense into water droplets, dissolve acidic gas molecules in the exhaust gas, and generate acidic substances, causing corrosion and wear of the cylinder wall. Experiments have shown that when the cylinder wall temperature drops from 90 ℃ to 50 ℃, the cylinder wear is four times that of 90 ℃. Excessive temperature can reduce the strength of the cylinder and exacerbate wear, and may even cause the piston to expand excessively, leading to "cylinder expansion" accidents.
5. Improve warranty quality: During use, promptly identify and eliminate problems, and replace or repair damaged and deformed parts at any time. Strictly inspect and assemble the 3NB1300C/1600 cylinder liner of Lanshi pump according to technical requirements. In the warranty replacement operation, it is necessary to choose a piston ring with appropriate elasticity. If the elasticity is too small, gas will enter the crankcase and blow off the oil on the cylinder wall, increasing the wear of the cylinder wall; Excessive elasticity directly exacerbates the wear of the cylinder wall, or exacerbates its wear due to the damage of the oil film on the cylinder wall. The crankshaft connecting rod journal and the main journal are not parallel. The engine may deform the crankshaft due to severe impact caused by burning tiles and other reasons. If not calibrated in time and continued to be used, it will also accelerate the wear of the 3NB1300C/1600 cylinder liner of the Lanshi pump.
Now we all know that newly purchased cars must be well maintained in order to extend their lifespan. The same applies to the 3NB1300C/1600 cylinder liner of Lanshi pump, and maintenance work must be done on the 3NB1300C/1600 cylinder liner of Lanshi pump. What should be done specifically? Let's take a closer look:
Under normal driving conditions, the brake shoes should be checked every 5000 kilometers, not only to check the remaining thickness, but also to check the wear status of the brake shoes, whether the degree of wear on both sides is the same, and whether they can recover freely. Any abnormal situation must be dealt with immediately.
2. Brake shoes are generally composed of iron lining plates and friction materials. They must be replaced in a timely manner and should not be replaced before severe polishing. Some vehicles are equipped with brake shoe warning function. Once the wear limit is reached, the instrument will sound an alarm, prompting to change shoes. Shoes that have reached their usage limit must be replaced. Even if it can still be used for a period of time, the braking effect will decrease, affecting driving safety.
When replacing, the brake pads provided by the original factory accessories should be replaced. Only in this way can the braking effect between the brake pads and brake discs be optimal with minimal wear.
When replacing the brake shoes, tools must be used to push back the brake cylinder. Do not use other pry bars to press back, as this can easily cause the lead screw of the brake caliper to bend, resulting in the brake pads getting stuck.
After replacing the brake shoes, it is necessary to break in for 200km to achieve the best braking effect.
New shoes must be driven with caution. After changing shoes, it is necessary to apply the brakes several times to eliminate the gap between the shoes and the brake disc, which can cause the foot to not brake and increase the risk of accidents.
When driving, be sure to follow the instructions above to maintain the 3NB1300C/1600 cylinder liner of the Lanshi pump. This can be more convenient and practical, and reduce costs.
