Service HotlineWith the continuous improvement of our living standards, various industries have also developed, which has driven the development of Baoji Pump F1300/1600 cylinder liners. Now the F1300/1600 cylinder liner of Baoji Pump has won the trust of a large number of users, but there are also some precautions for Baoji Pump F1300/1600 cylinder liner that need to be understood by a large number of users. Today, we will provide a detailed introduction:
During the use of Baoji pump F1300/1600 cylinder liner, maintenance of the filter screen should be strengthened. Keeping the air filter, oil filter, and fuel filter in good working condition is crucial for reducing wear on the F1300/1600 cylinder liner of Baoji pump. Strengthening the maintenance of the "three filters" is an important measure to prevent mechanical impurities from entering the cylinder, reduce the wear of the F1300/1600 cylinder liner of Baoji pump, and extend the service life of the engine.
2. The F1300/1600 cylinder liner of Baoji pump should be lubricated with the correct oil during use. Viscosity lubricating oil should be strictly selected 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. Improve the quality of warranty. During use, promptly identify and eliminate problems, and replace or repair damaged or deformed components at any time. When installing the F1300/1600 cylinder liner of Baoji pump, strict inspection and assembly should be carried out according to technical requirements. In the operation of replacing the warranty ring, a piston ring with appropriate elasticity should be selected. If the elasticity is too small, it will cause gas to enter the crankcase, blow off the oil on the cylinder wall, and increase the wear of the cylinder wall; Excessive elasticity can directly exacerbate the wear of the cylinder wall or damage the oil film on the F1300/1600 cylinder liner wall of Baoji pump.
4. Maintain the normal operating temperature of the engine. The normal operating temperature of the engine should be 80-90 ℃. If the temperature is too low to maintain good lubrication, it will increase the wear of the cylinder wall. The water vapor in the F1300/1600 cylinder liner of Baoji pump is prone to condense into water droplets, dissolve acidic gas molecules in the exhaust gas, and generate acidic substances, resulting in corrosion and wear of the F1300/1600 cylinder liner wall of Baoji pump. Experiments have shown that when the wall temperature of the F1300/1600 cylinder liner of Baoji pump drops from 90 ℃ to 50 ℃, the cylinder wear is four times that of 90 ℃. Excessive temperature can reduce the strength and wear of the cylinder, and even cause the piston to expand excessively, resulting in "cylinder expansion" accidents.
Start and start correctly. When the engine is started cold, the low oil temperature, high viscosity, and poor fluidity cause insufficient oil supply from the oil pump. At the same time, the oil on the F1300/1600 cylinder liner of the original Baoji pump flowed down along the cylinder wall after parking, and could not be well lubricated at the moment of starting as it did during normal operation, greatly increasing the wear of the F1300/1600 cylinder liner wall of the Baoji pump during start-up. So when starting, the engine should idle a few times and wait for the friction surface to lubricate before starting. After starting, idle and preheat. It is strictly prohibited to forcefully tap the oil port. Wait until the standby oil temperature reaches 40 ℃ before starting. When starting, you should stick to low gear and drive a certain distance in each gear until the oil temperature is normal before switching to normal driving.
Analysis of wear of Baoji pump F1300/1600 cylinder liner The working environment of Baoji pump F1300/1600 cylinder liner is very harsh, and there are many reasons for wear. Normally, normal wear and tear is allowed due to structural reasons, but improper use and maintenance can cause abnormal wear and tear.
I. Analysis of Wear Causes of F1300/1600 Cylinder Liner in Baoji Pump
1. Long term low-temperature operation. Long term low-temperature operation is caused by poor combustion, with carbon deposits spreading from the upper part of the F1300/1600 cylinder liner of Baoji pump, resulting in severe abrasive wear on the upper part of the F1300/1600 cylinder liner of Baoji pump; The second is to cause electrochemical corrosion.
2. The high pressure in the upper part causes the cylinder to wear more than lightly. The piston ring is pressed against the cylinder wall by its own elasticity and back pressure. The greater the positive pressure, the more difficult it is to form and maintain a lubricating oil film, and the more severe the mechanical wear. During the power stroke, as the piston descends, the positive pressure gradually decreases, so the wear of the cylinder is heavier at the top and lighter at the bottom.
3. The entry of mechanical impurities will exacerbate the wear in the middle of the cylinder. Dust in the air, impurities in lubricating oil, etc. Entering between the piston and cylinder wall, causing wear. When dust or impurities move back and forth with the piston in the cylinder, the speed of movement in the middle of the cylinder intensifies the wear in the middle of the cylinder.
4. The filtering effect of the lubricating oil filter is poor. If the lubricating oil filter does not work properly, the lubricating oil cannot be effectively filtered, and the lubricating oil containing a large amount of hard particles will inevitably exacerbate the wear of the inner wall of the F1300/1600 cylinder liner of Baoji pump.
5. The filtration efficiency of the air filter is low. The function of an air filter is to remove dust and sand particles from the air entering the cylinder, thereby reducing wear on the cylinder, piston, and piston rings. Experiments have shown that if the engine is not equipped with an air filter, cylinder wear will increase by 6-8 times. If the air filter is not cleaned and maintained for a long time, the filtering effect will be poor, which will accelerate the wear of the F1300/1600 cylinder liner of Baoji pump.
Poor lubrication conditions have caused severe wear on the upper part of the F1300/1600 cylinder liner of Baoji pump. The upper part of the F1300/1600 cylinder liner of Baoji pump is adjacent to the combustion chamber, with high temperature and poor lubrication conditions. The erosion and dilution of fresh air and unevaporated fuel exacerbate the deterioration of the upper working conditions, causing the cylinder to be in a dry or semi dry friction state, which is the reason for severe wear on the upper part of the cylinder.
Correct selection of lubricating oil: Lubricating oil with viscosity values should be selected strictly according to the season and engine performance requirements. It is not allowed to purchase inferior lubricating oil at will, and the quantity and quality of lubricating oil should be regularly checked and maintained. Strengthening the maintenance of filters to maintain good working condition of air filters, oil filters, and fuel filters is crucial for reducing the wear of F1300/1600 cylinder liners in Baoji pumps. These methods can effectively maintain the F1300/1600 cylinder liner of the Baoji pump engine.
